Description: BACKGROUND OF THE INVENTION The present invention relates to a nozzle and a molding system for use in producing a solidified article, having a predetermined composite pattern, and a method for producing such a solidified article. PRIOR ART Solidified articles formed by molding and solidifying viscous fluids, such as solidified chocolates, have hitherto been produced by a method wherein the liquid chocolate to be molded is measured by a depositor (a volume regulating filling machine),while the liquid chocolate is stirred in a storage tank thereof for maintaining the homogenous state of the liquid chocolate, and charged into a desired mold. In this method, a molding system is adopted wherein a single kind of liquid chocolate is guided through a single discrete passage to a desired single unit mold for molding a single solidified chocolate (solidified article). On the other hand, for forming a composite pattern on the solidified chocolate, two kinds of liquid chocolates are stored together in a single tank, measured in the mixed state, and charged into a desired unit mold, since the two kinds of liquid chocolates are previously mixed prior to the measurement, the ratio of the liquid chocolates in each solidified chocolate to be produced is different, so that solidified chocolates having the same (uniform) composite pattern (solidified articles having a predetermined composite pattern formed of at least two kinds of viscous fluids) cannot be produced. Alternatively, there is proposed a method for producing a solidified article having a composite pattern, wherein a desired liquid chocolate is dotted onto the inner surface of the mold by a brush or the like, and another kind of liquid chocolate is charged by the depositor to form the composite pattern. However, this method requires a great amount of time and effort in the time-consuming dotting process. Further, each of the obtained solidified chocolates has a different composite pattern, as in the above case. US-A-4 184 613 discloses a product patterning means having an outlet and a plurality of inlet means. The patterning means includes a tubular pattering chamber which is subdivided into a plurality of tubular pattern conduits. All of the pattern conduits have only one outlet. JP 63 301747 A discloses a method for producing a molded chocolate using a mold and a separation mold, wherein one kind of chocolate is poured into a corresponding part of the mold, and when that kind of chocolate has solidified, another kind of chocolate is poured thereon. That is, this method includes repeated steps of pouring and solidifying chocolates in order to produce one solidified article. US-A-4 369 200 discloses a method for producing fatty confectionaries having three-dimensional decoration deposited thereon using a mold having recesses and a plate mold having through holes corresponding to the recesses. This method includes the steps of placing the plate mold on the mold, with the through holes in alignment with the recesses, spraying confectionary material through the through holes, removing the plate mold, pouring base material of different colour into the mold, and cooling and solidifying the material. EP-A-0 221 757 discloses a method for producing an ice cream product containing chocolate including the steps of issuing ice cream from an ice cream nozzle, and ejecting chocolate toward a stream of the ice cream so as to deeply penetrate the ice cream.

The present invention is made in view of the above objects. A nozzle according to the present invention is defined in claim 1. A molding system according to the present invention is defined in claim 5. A method according to the present invention is defined in claim 15. Further developments and modifications of the invention are defined in the depending claims. In the present invention, "at least two viscous fluids distinct from each other in color" means two kinds of viscous fluids which are different in strength of color, or thickness of color, or in tone, and additionally in other properties such as viscosity. The solidified article having a "composite pattern" include a solidified article having a pattern wherein the boundaries in a specific pattern such as striped or staggered pattern formed of at least two viscous fluids are mingled or mixed on at least a portion of the solidified article, or a solidified article having a marbled pattern on a portion of or entire body of the solidified article. The at least one discrete passage per each of said viscous fluids for separately guiding each of the viscous fluids may be an independent single passage, or a branched passage, and these may be employed in combination as desired. The discrete passage per each of said viscous fluids may be provided as follows: one discrete passage is provided for guiding one kind of viscous fluid so that the total number of the discrete passage is equal to the number of kinds of the viscous fluids; two or more discrete passages are provided for guiding each of the viscous fluids; two or more discrete passages are provided for guiding one kind of viscous fluid, and branched discrete passages are provided for guiding other viscous fluids; branched discrete passages are provided for guiding each of the viscous fluids; or other combinations of the discrete passages may also be employed as desired. In any case, two or more kinds of viscous fluids are not guided in a single discrete passage. The viscous fluids are never mixed in the discrete passage. The discrete passage outlets may be arranged in a plane facing a unit mold or a conveyer regularly or irregularly. For example, in the case wherein two kinds of the viscous fluids A and B are employed, the discrete passages for guiding the viscous fluids A and B may be arranged regularly such as "ABAB ·· ·", "AABAAB · · · ", or "ABAABBAAABBB · · · "; or irregularly such as "AABABBAB · ". The discrete passages may be arranged adjacent to each other or arbitrary. The configuration and number of the discrete passage outlets may be determined one by one, as a unit, or arbitrary. The unit mold means a mold for forming a single solidified article itself. The uniting passage means a passage for collecting the streams of at least two viscous fluids discharged through at least two discrete passage outlets When this uniting passage is configured so that the inner surface there of is tapered radially inwardly toward the flow direction of the viscous fluids, the streams of the viscous fluids discharged through the discrete passage outlets may be collected, merged, and/or mixed as desired. The uniting passage may be of any cross sectional shape or number, and a plurality of uniting passages are arbitrarily combined in parallel or in series in the flow direction of the viscous fluids as desired. The uniting passage may have a plate having at least one orifice therein, disposed in the middle of the uniting passage in a plane transverse to the flow direction of the viscous fluids through the uniting passage. With this embodiment, a predetermined composite pattern or a predetermined mingled composite pattern of the solidified article is suitably mixed to a desired extent depending on the combination thereof. A timing means may be, for example, means for setting and maintaining the discharge timing of each of the viscous fluids at a depositor for measuring each of the viscous fluids, or other known means may be used. In the present invention, "carry out the step of 'supplying said at least two kinds of viscous fluids separately' intermittently" means to measure each of the viscous fluids separately, and to supply each of the measured viscous fluids at every predetermined time. As a specific means for this process, a depositor (a device for charging predetermined amount) may be used. On the other hand, "carry out the step of 'supplying said at least two kinds of viscous fluids separately' continuously" means to supply each of the viscous fluids continuously at a predetermined ratio without stopping. As a specific means for this process, a pump for high viscosity fluids such as a gear pump or a snake pump may be used. Similarly, "carry out the steps of 'passing each of said separately supplied viscous fluids', 'discharging said viscous fluids from said at least one discrete passage', 'passing at least two kinds of said viscous fluids', and 'discharging said at least two kinds of said viscous fluids from the uniting passage' intermittently", and "carry out the steps of 'passing each of said separately supplied viscous fluids', 'discharging said viscous fluids from said at least one discrete passage', 'passing at least two kinds of said viscous fluids', and 'discharging said at least two kinds of said viscous fluids from the uniting passage' continuously" is interpreted in the similar manner as described above. The conveyer used for the present invention functions also as molds, and specific embodiments of the conveyer may include a conveyer having a simple plane surface (Fig. 1(c)), a conveyer having side walls on either sides of the belt (Fig. 11(a)), a conveyer substantially having molds (Fig. 11(b)), and a conveyer having a belt provided with desired configuration thereon (Fig. 11(c)). Specifically, when the conveyer having side walls on either sides of the belt (Fig. 11(a)), or the conveyer substantially having molds (Fig. 11(b)) is used, fluidization of the viscous fluids may be stopped within a desired area depending on the fluidizing degree (viscosity) of the viscous fluids. When the conveyer having a belt provided with desired configuration thereon (Fig. 11(c)) is used, solidified articles of a specific configuration having a predetermined composite pattern may be mass-produced. In the present invention, the solidified article to be produced and the viscous fluids may be a food material which is in a liquid state and can be solidified into a solid state by cooling or heating, for example, chocolate, ice deserts, jelly, butter, cheese and so on. When the present molding system, method for producing a solidified article, an apparatus, or a method for producing solidified articles is used with such food materials, solidified food articles having stabilized appearance and quality can be mass-produced easily and accurately.

PREFERRED EMBODIMENTS OF THE INVENTION The present invention will now be explained in more detail with reference to Examples, but the present invention is not limited thereto. Example 1 The molding system of the present invention is used for producing a solidified article, for example, a solidified chocolate, having a predetermined composite pattern formed of two kinds of viscous fluids, for example, liquid chocolate A and B. As shown in Figs. 1 and 2, the molding system includes a porous nozzle 10 having a plurality of discrete passages 11, 12 (Figs. 2(a), 2(b)) penetrating therethrough for separately guiding predetermined amount of each of the liquid chocolate A and B which has been measured separately in advance by a depositor (not shown), and a uniting nozzle 20 (Fig. 1(b)) communicating with outlets 11a' to 11h' and 12a' to 12h' of the discrete passages 11, 12 for collecting streams of the liquid chocolate A, B together which have been guided by the discrete passages 11, 12 to further guide the same to a unit mold 30. The plurality of discrete passages 11 (Fig. 2(b)) penetrating the porous nozzle 10 guide the liquid chocolate A to the unit mold 30, and each of the discrete passages 11 has an inlet 11a to 11h for receiving the liquid chocolate measured by the depositor, and an outlet 11a' to 11h' for simultaneously discharging the liquid chocolate A received through the inlet 11a to 11h to the unit mold 30. On the other hand, the plurality of discrete passages 12 (Fig. 2(a)) penetrating the porous nozzle 10 guide the liquid chocolate B to the unit mold 30, and each of the discrete passages 12 has an inlet 12a to 12h for receiving the liquid chocolate measured by the depositor, and an outlet 12a' to 12h' for simultaneously discharging the liquid chocolate B received through the inlet 12a to 12h to the unit mold 30. The outlets 11a' to 11h' of the discrete passages 11 and the outlets 12a' to 12h' of the discrete passages 12 are arranged alternately in circles in a predetermined plane facing the unit mold 30, through which outlets the liquid chocolate A and B are discharged separately and generally simultaneously in a predetermined state. The nozzle for separately guiding each of the liquid chocolate A and B to the unit mold 30 may be a nozzle wherein the liquid chocolate A and B are guided by additional discrete passages branched upstream of the discrete passages 11, 12, or a porous nozzle wherein the discrete passages 11, 12 themselves are branched (Figs. 3(a) and 3(b)) to be discussed later, in place of the porous nozzle 10. The uniting nozzle 20 communicating with the outlets 11a' to 11h' of the discrete passages 11 and the outlets 12a' to 12h' of the discrete passages 12 has a contour of a reversed truncated cone having a tapered surface as shown in Fig. 1(b). The uniting nozzle 20 receives the streams of the liquid chocolate A, B discharged through the outlets 11a' to 11h' of the discrete passage 11 and the outlets 12a' to 12h' of the discrete passage 12 via an inlet 21a, collects the received streams of the chocolate A, B together by a uniting passage 21, and discharges the chocolate A, b through an outlet 21a' provided at the lower end of the uniting nozzle 20, thereby guiding the chocolate A, B to the unit mold 30. The uniting nozzle for collecting the streams of the chocolate A, B together for guiding the same to the unit mold 30 may be other uniting nozzles 40 as shown in Figs. 4(a) to 4(c) to be discussed later, in place of the uniting nozzle 20. By the uniting nozzle, the streams of the liquid chocolate A, B discharged from the porous nozzle 10 in a predetermined state may be merged into a predetermined collected state, or into a predetermined suitably mixed state for discharging therefrom. As explained above, according to the molding system of the present invention, each of the liquid chocolate A, B measured in advance by the depositor (not shown) is received by the porous nozzle 10 through the inlets 11a to 11h of the discrete passages 11 and the inlets 12a to 12h of the discrete passages 12, and discharged through the plurality of outlets 11a' to 11h' and 12a' to 12h' arranged alternately in circles in the predetermined plane facing the unit mold 30. The streams of the discharged chocolate A, B are collected together by the uniting passage 21 of the uniting nozzle 20, and guided to an accommodating portion of the unit mold 30. For producing a solidified article, for example, a solidified chocolate, having a predetermined composite pattern formed of two kinds of viscous fluids, for example, liquid chocolate A, B, using the above molding system, first predetermined amounts of each of the liquid chocolate A, B are separately measured by a depositor (not shown), separately guided through the discrete passages 11, 12 of the porous nozzle 10, discharged through the outlets 11a' to 11h' of the discrete passages 11 and the outlets of 12a' to 12h' of the discrete passages 12 arranged alternately in circles in the predetermined plane facing the unit mold 30. The streams of the discharged chocolate A, B are collected together by the uniting passage 21 of the uniting nozzle 20, guided to the accommodating portion 31 of the unit mold 30, and molded and solidified in the unit mold 30, thereby producing the solidified chocolate (a solidified article) having a predetermined composite pattern. In molding and solidifying the chocolate A, B in the above process, a cooling machine may additionally be used, or a heating machine may also be used depending on the viscous fluid to be molded and solidified. According to the present invention, the uniting nozzle 20 of the present embodiment may be eliminated in practice. In this alternate embodiment, mingling of the composite pattern formed of the two liquid chocolate A, B may be reduced. In producing a solidified chocolate having a predetermined composite pattern with the molding system of the present invention which is not equipped with the uniting nozzle 20, like the process as described above, first predetermined amounts of each of the liquid chocolate A, B are separately measured by a depositor (not shown), separately guided through the discrete passages 11, 12 of the porous nozzle 10, and discharged through the outlets 11a' to 11h' of the discrete passages 11 and the outlets of 12a' to 12h' of the discrete passages 12 arranged alternately in circles in the predetermined plane facing the unit mold 30 into the accommodating portion 31 of the unit mold 30. The liquid chocolate A, B poured into the accommodating portion 31 of the unit mold 30 is molded and solidified therein, thereby giving a solidified chocolate (solidified article) having a predetermined composite pattern. In the molding system of the present invention, other porous nozzles 10 as shown in Figs. 3(a) and 3(b) may be used in place of the porous nozzle 10 in Fig. 1(a). The porous nozzle 10 shown in Fig. 3(a) is provided with a surrounding wall 13 disposed radially outwardly of and surrounding the inlets 11a to 11h of the discrete passages 11 (corresponding to the discrete passages 11 in Fig. 2(b)), and a surrounding wall 14 disposed radially inwardly of the inlets 11a to 11h of the discrete passages 11 (corresponding to the discrete passages 11 in Fig. 2(b)) and radially outwardly of and surrounding the inlets 12a to 12h of the discrete passages 12 (corresponding to the discrete passages 12 in Fig. 2(a)). With the porous nozzle 10 (Fig. 3(a)), each of the liquid chocolate A, B may be separately introduced into areas defined by the surrounding walls 13, 14, respectively, so that the liquid chocolate A, B may be received through the respective inlets 11a to 11h and 12a to 12h of the discrete passages, and discharged through the outlets 11a' to 11h' and 12a' to 12h'. The porous nozzle 10 in Fig. 3(b) is provided with a discrete passage 11 (corresponding to the discrete passage 11 in Fig. 2(b)) branched in the middle and having a single inlet 11' and a plurality of outlets 11a' to 11h', and a discrete passage 12 (corresponding to the discrete passage 12 in Fig. 2(a)) branched in the middle and having a single inlet 12' and a plurality of outlets 12a' to 12h'. With the porous nozzle 10 (Fig. 3(b)), each of the liquid chocolate A, B may be introduced into the single inlet 11', 12' of each of the discrete passages, respectively, so that the liquid chocolate may be discharged in a predetermined state through the outlets 11a' to 11h' and 12a' to 12h'. In the molding system of the present invention, other uniting nozzles 40 as shown in Figs. 4(a) to 4(c) may be used in place of the uniting nozzle 20 in Fig. 1(b). The uniting nozzle 40 as shown in Fig. 4(a) is provided with a uniting passage 41 having a single inlet 41a and three outlets 41a', 41a", 41'", so that it functions to receive the streams of the liquid chocolate A, B (viscous fluids) discharged from the porous nozzle 10 through the inlet 41a, and merge the streams before they are discharged. Therefore, a solidified chocolate (solidified article) having a suitably mingled predetermined composite pattern may be produced. The uniting nozzle 40 in Fig. 4(b) is a modified embodiment of the uniting nozzle 40 in Fig. 4(a), wherein the uniting nozzle is provided with a plate 42 having an orifice 42a, disposed in the middle of the uniting passage 41 of the uniting nozzle in a plane transverse to a flow direction of the liquid chocolate A, B (viscous fluid) through the uniting passage. This uniting nozzle 40 functions to collect the streams of the chocolate A, B (viscous fluids) discharged through the outlets 11a' to 11h' and 12a' to 12h' of the porous nozzle 10 together, merges the streams, and wring out the merged streams of the liquid chocolate. Thus, a solidified chocolate (solidified article) having a predetermined composite pattern suitably mingled to a predetermined degree can be produced. The uniting nozzle 40 as shown in Fig. 4(c) is a modified embodiment of the uniting nozzle 20 in Fig. 1(b) wherein the uniting nozzle is provided with a plate 42 having a plurality of orifices 42a to 42c (three orifices are shown in the drawings), disposed in the middle of the uniting passage 41 of the uniting nozzle in a plane transverse to a flow direction of the liquid chocolate A, B through the uniting passage. The streams of the liquid chocolate A, B discharged from the porous nozzle 10 through the outlets 11a' to 11h' and 12a' to 12h' is received through the inlet 41a, collected together, passed through the orifices 42a to 42c disposed in the middle of the passage, and discharged through the outlet 41a' . Thus, the streams of the liquid chocolate A, B (a plurality of viscous fluids) discharged from the discrete passages 11, 12 through the outlets 11a' to 11h' and 12a' to 12h' may be merged to a desired extent and discharged in a predetermined state, thereby giving a solidified chocolate (solidified article) having a predetermined composite pattern suitably mingled to a desired extent. In this Example, the porous nozzle 10 has been described as having the discrete passages 11, 12 for separately guiding each of the liquid chocolate A, B integrally formed therein, but the porous nozzle of the present invention is not limited thereto. For example, the porous nozzle may be an assembly of a plurality of parts such as a nozzle provided with a discrete passage 11 for guiding mainly the liquid chocolate A, and a nozzle provided with a discrete passage 12 for guiding mainly the liquid chocolate B. With this embodiment, a solidified chocolate (a solidified article) having a predetermined composite pattern may be produced simply by arbitrarily combining each parts, and each parts may be detached easily for cleaning, thus being remarkably advantageous. Further, the number of the outlets of each passage (discrete passages 11, 12 and uniting passage 21) may be decided as desired; the configuration of the outlet may be decided as desired, such as triangle, rectangle, oval, or the like; and the arrangement of the outlets may be decided as desired, for example, the outlets may be arranged alternately in circles, or in a staggered pattern, regularly, or irregularly. The unit mold used in the present invention may have any shape, such as a shape representing a desired article. Further, the composite pattern to be formed with the solidified chocolate (solidified article) may also be controlled by changing the point in the unit mold 30 on which the liquid chocolate A, B (viscous fluids) falls which is finally discharged through the outlets disposed facing the unit mold 30. Alternatively, the configurations of the porous nozzle provided with the discrete passages and the uniting nozzle provided with the uniting passage is not limited to the reversed truncated cone, and may be any desired shape such as a rectangular parallelepiped. Example 2 Another embodiment of the molding system of the present invention is now described with reference to Figs. 5 and 6. This molding system is used for producing a covered solidified chocolate (solidified article) wherein a liquid chocolate C is accommodated in the middle covered with two kinds of liquid chocolate A, B (viscous fluids) forming a predetermined composite pattern therearound. The molding system includes a porous nozzle 50 having a plurality of discrete passages 51 to 53 (Figs. 6(a), 6(b)) penetrating therethrough for separately guiding predetermined amount of each of the liquid chocolate A to C which have been measured in advance by a depositor (not shown), and a uniting nozzle 60 (Fig. 5(b)) communication with the outlets 51a' to 51h', 52a' to 52h', 53a' of the discrete passages 51 to 53. A unit mold 70 (Fig. 5(c)) for forming a single solidified chocolate is used with these nozzles. Timing for discharging each of the liquid chocolate A to C from each of the discrete passages is controlled at the depositor such that discharging of the liquid chocolate A and B from the discrete passages through the outlets 51a' to 51h', 52a' to 52h', respectively, start generally simultaneously, but discharging of the liquid chocolate C through the outlet 53a' starts later and stops earlier than the discharging of the liquid chocolate A and B, and this timing is maintained. The plurality of discrete passages 51 (Fig. 6(b)) penetrating the porous nozzle 50 guide the liquid chocolate A to the unit mold 70. The discrete passages 51 are provided with inlets 51a to 51h for receiving predetermined amount of the liquid chocolate A measured by the depositor in advance, and outlets 51a' to 51h' for discharging the liquid chocolate A received through the inlets to the unit mold 70. The plurality of discrete passages 52 (Fig. 6(a)) penetrating the porous nozzle 50 guide the liquid chocolate B to the unit mold 70 similarly to the discrete passages 51. The discrete passages 52 are provided with inlets 52a to 52h for receiving predetermined amount of the liquid chocolate B measured by the depositor in advance, and outlets 52a' to 52h' for discharging the liquid chocolate B received through the inlets to the unit mold 70. The outlets 51a' to 51h' of the discrete passage 51, and the outlets 52a' to 52h' of the discrete passage 52 are arranged alternately in circles in a predetermined plane facing the unit mold 70. The single discrete passage 53 penetrating the center of the porous nozzle 50 guides the liquid chocolate C to the unit mold 70, and is provided with an outlet 53a for receiving predetermined amount of the liquid chocolate C measured by a depositor in advance, and an outlet 53a' for discharging the liquid chocolate C received through the inlet 53a to the unit mold 70. With this structure, the liquid chocolate A and B are discharged through the outlets 51a' to 51h' and 52a' to 52h' arranged as desired into the unit mold 70 in a predetermined state, and the liquid chocolate C is discharged into the center of the unit mold 70. The nozzle for separately guiding each of the liquid chocolate A to C to the unit mold 70 may be a nozzle wherein the liquid chocolate A to C are guided by additional discrete passages branched upstream of the discrete passages 51 to 53 of the porous nozzle, or a porous nozzle wherein the discrete passages 51 to 52 themselves are branched (Figs. 7(a), 7(b)) as to be discussed later, in place of the porous nozzle 50. The uniting nozzle 60 communicating with the outlets 51a' to 51h', 52a' to 52h', 53a' of the discrete passages 51 to 53 has a contour of a reversed truncated cone having a tapered surface as shown in Fig. 5(b). The uniting nozzle 60 receives the streams of the liquid chocolate A to C discharged from the discrete passages 51 to 53 through the outlets 51a' to 51h', 52a' to 52h', 53a' via an inlet 61a, collects the received streams of the chocolate A to C together by a uniting passage 61, and discharge the chocolate A to C through an outlet 61a' provided at the lower end of the uniting nozzle 60, thereby guiding the chocolate A to C to the unit mold 70. The uniting nozzle for guiding the liquid chocolate A to C discharged from the porous nozzle to the unit mold 70 may be other uniting nozzles 80 as shown in Figs. 8(a), 8(b) to be discussed later, in place of the uniting nozzle 60. By the uniting nozzle, the streams of the liquid chocolate A to C discharged from the porous nozzle 50 in a predetermined state may be merged into a predetermined collected state for discharging therefrom. In molding the liquid chocolate A to C in the unit mold 70 in this Example, discharge of the liquid chocolate C is controlled to start later and stop earlier than the discharge of the liquid chocolate A and B, so that previously discharged liquid chocolate A and B first cover the bottom portion of the accommodating portion 71 of the unit mold 70 (the top portion when the article is demolded) and the vicinity thereof, and then the liquid chocolate C is discharged on and in the center of the previously covered portion. The liquid chocolate C is finally covered by the liquid chocolate A and B. As described above, according to the molding system of the present invention, the predetermined amount of liquid chocolate A to C measured by the depositor (not shown ) in advance are separately received through the inlets 51a to 51h, 52a to 52h, 53a of the discrete passages 51 to 53 of the porous nozzle 50, discharged through the plurality of outlets 51a' to 51h', 52a' to 52h', 53a' arranged alternately in circles in the predetermined plane facing the unit mold 70. The streams of the liquid chocolate A to C discharged from the porous nozzle 50 are then collected together by a uniting nozzle 60, and guided to the accommodating portion 71 of the unit mold 70. In producing a covered solidified chocolate (solidified article) having the liquid chocolate C accommodated inside and the predetermined composite pattern formed of the two kinds of liquid chocolate A, B (viscous fluids) covering the liquid chocolate C with the molding system described above, first predetermined amounts of each of the liquid chocolate A to C are separately measured by a depositor (not shown) . Then each of the predetermined amount of the liquid chocolate A and B is guided by the discrete passages 51 and 52, respectively, so that the liquid chocolate A and B are discharged through the outlets 51a' to 51h', and 52a' to 52h', respectively, arranged alternately in circles in the predetermined plane facing the unit mold 70, into the inner surface of the accommodating portion 71 of the unit mold 70, and the predetermined amount of the liquid chocolate C is guided by the discrete passage 53, so that the liquid chocolate C is discharged through the outlet 53a' surrounded by the outlets 51a' to 51h' and 52a' to 52h' and placed in the center thereof into approximately the center of the accommodating portion 71 of the unit mold 70. In this process, the discharge of the liquid chocolate C is controlled to start later and stop earlier than the discharge of the liquid chocolate A and B. The streams of the liquid chocolate A and B discharged through the outlets 51a' to 51h' and 52a' to 52h' arranged alternately in circles and the stream of the liquid chocolate C discharged through the outlet 53a' surrounded by the outlets 51a' to 51h' and 52a' to 52h' are collected together by the uniting nozzle 60, and guided to the accommodating portion 71 of the unit mold 70 to mold and solidify the liquid chocolate A to C, thereby producing the covered solidified chocolate (covered solidified article) having the predetermined composite pattern. In molding and solidifying the liquid chocolate A to C in the above process, a cooling machine may additionally be used, or a heating machine may also be used depending on the viscous fluid to be molded and solidified. In the molding system of the present invention, the porous nozzle 50 (Fig. 5(a)) may be replace by other porous nozzles 50 as shown in Figs. 7(a) and 7(b). The porous nozzle 50 as shown in Fig. 7 (a) is provided with a surrounding wall 54 disposed radially outwardly of and surrounding the inlets 51a to 51h of the discrete passages 51 (corresponding to the discrete passages 51 in Fig. 6(b)), a surrounding wall 55 disposed radially inwardly of the inlets 51a to 51h of the discrete passages 51 (corresponding to the discrete passages 51 in Fig. 6(b)) and radially outwardly of and surrounding the inlets 52a to 52h of the discrete passages 52 (corresponding to the discrete passages 52 in Fig. 6(a)), and a surrounding wall 56 disposed radially inwardly of the inlets 52a to 52h of the discrete passage 52 (corresponding to the discrete passage 52 in Fig. 6(a)) and radially outwardly of and surrounding the inlet 53a of the discrete passage 53. With the porous nozzle 50 (Fig. 7(a)), each of the liquid chocolate A to C may be separately introduced into areas defined by the surrounding walls 54 to 56, respectively, so that the liquid chocolate A to C may be received through the respective inlets 51a to 51h, 52a to 52h, and 53a of the discrete passages, and discharged through the outlets 51a' to 51h', 52a' to 52h', and 53a' The porous nozzle 50 as shown in Fig. 7(b) is provided with a discrete passage 51 (corresponding to the discrete passages 51 in Fig. 6(b)) having a single inlet 51' and a plurality of outlets 51a' to 51h' and branched in the middle, a discrete passage 52 (corresponding to the discrete passages 52 in Fig. 6(a)) having a single inlet 52' and a plurality of outlets 52a' to 52h' and branched in the middle, and a discrete passage 53 (corresponding to the discrete passage 53 in Figs. 6(a) and 6(b)) having a single inlet 53a and a single outlet 53a'. With the porous nozzle (Fig. 7(b)), each of the liquid chocolate A to C may be introduced through the single inlet 51', 52', 53', respectively, of each of the discrete passages, and discharged through the outlets 51a' to 51h', 52a' to 52h', and 53a', respectively. Further, in the molding system of the present invention, the above mentioned uniting nozzle 60 (Fig.. 5(b)) may be replaced by other uniting nozzles 80 as shown in Figs. 8(a) and 8(b). The uniting nozzle 80 as shown in Fig. 8(a) is provided with a uniting passage 81 defined between two coaxially disposed inner and outer cylinders having radially inwardly tapered surfaces, and communicating with the outlets 51a' to 51h', 52a' to 52h' of the discrete passages 51, 52 of the porous nozzle 50 in Figs. 5(a), 6(a), and 6(b), and a discrete passage 82 defined by the inner cylinder, and communicating with the outlet 53a' of the discrete passage 53 of the porous nozzle 50. The uniting passage 81 receives through the inlet 81a streams of the liquid chocolate A and B discharged through the outlets 51a' to 51h', 52a' to 52h' of the discrete passages 51, 52 of the porous nozzle 50, collects them, and discharge the same through the outlet 81a'. On the other hand, the discrete passage 82 receives through the inlet 82a a stream of the liquid chocolate C discharged through the outlet 53a' of the discrete passage 53 of the porous nozzle 50, and discharge the same as it is through the outlet 82a'. As mentioned above, timing for discharging each of the liquid chocolate A to C from the outlets 81a', 82a' is controlled such that discharging of the liquid chocolate C via the discrete passage 53 of the porous nozzle 50 through the outlet 82a' of the discrete passage 82 of the uniting nozzle 80 starts later and stops earlier than the discharging of the liquid chocolate A and B via the discrete passages 51, 52 of the porous nozzle 50 through the outlet 81a' of the uniting passage 81 of the uniting nozzle 80. With the uniting nozzle 80 (Fig. 8(a)), the liquid chocolates A to C can be poured into the unit mold so that the liquid chocolate C is accommodated inside and surrounded by the liquid chocolate A and B, while the streams of the liquid chocolate A and B are collected together into a predetermined state. Accordingly, the covered solidified chocolate wherein the liquid chocolate C is accommodated in the middle covered with two kinds of liquid chocolate A and B forming a predetermined composite pattern therearound can accurately be produced. The uniting nozzle 80 as shown in Fig. 8(b) is a modification of the uniting nozzle 80 as shown in Fig. 8(a) wherein a plate 83 having orifices is provided in the middle of the uniting passage 81 in a plane transverse to the flow direction of the liquid chocolate A, B (viscous fluids) through the uniting nozzle 80. The streams of the liquid chocolate A and B discharged from the discrete passages 51 , 52 of the porous nozzle 50 through the outlets 51a' to 51h', 52a' to 52h' are received through the inlet 81a, collected together, and passed through the plurality of orifices (e.g. 83a, 83b) of the plate 83. Further, the streams of the liquid chocolate passed through the plurality of orifices are merged again, and discharged through the outlet 81a'. The timing of discharge of the liquid chocolate A to C is the same as formerly described with reference to the uniting nozzle 80 as shown in Fig. 8(a). With the uniting nozzle 80 (Fig. 8(b)), the liquid chocolates A to C can be poured into the unit mold so that the liquid chocolate C is accommodated inside and surrounded by the liquid chocolate A and B, while the streams of the liquid chocolate A and B are collected together into a predetermined state. Accordingly, the covered solidified chocolate wherein the liquid chocolate C is accommodated in the middle covered with two kinds of liquid chocolate A and B forming a predetermined composite pattern therearound can be produced easily and accurately. In the present Example, the porous nozzle 50 has been described as having the discrete passages 51 to 53 for separately guiding each of the liquid chocolate A to C integrally formed therein, but the porous nozzle of the present invention is not limited thereto. For example, the porous nozzle may be an assembly of a plurality of parts such as a nozzle provided with a discrete passage 51 for guiding mainly the liquid chocolate A, a nozzle provided with a discrete passage 52 for guiding mainly the liquid chocolate B, and a nozzle provided with a discrete passage 53 for guiding mainly the liquid chocolate C. With this embodiment, a covered solidified chocolate (a solidified article) having a predetermined composite pattern may be produced simply by arbitrarily combining each parts, and each parts may be detached easily for cleaning, thus being remarkably advantageous. Further, the number of the outlets of each passage (discrete passages 51 to 53, 82 and uniting passage 61, 81) may be decided as desired; the configuration of the outlet may be decided as desired, such as triangle, rectangle, oval, or the like; and the arrangement of the outlets may be decided as desired, for example, the outlets may be arranged alternately in circles, or in a staggered pattern, regularly, or irregularly. The unit mold used in the present invention may have any shape, such as a shape representing a desired article. Further, the composite pattern to be formed with the solidified chocolate (solidified article) may also be controlled by changing the point in the unit mold on which the liquid chocolate A to C (viscous fluids) falls which is finally discharged through the outlets disposed facing the unit mold. Alternatively, in the porous nozzle 50, the discrete passage 53 may be branched, and a portion of the liquid chocolate guided by the discrete passage 53 may be discharged for use as the viscous fluid for forming the composite pattern. Further, the configurations of the porous nozzle provided with the discrete passages and the uniting nozzle provided with the discrete passage and the uniting passage are not limited to the reversed truncated cone, and may be any desired shape such as a rectangular parallelepiped.

For example, the porous nozzle may be an assembly of a plurality of parts such as a nozzle provided with a discrete passage 11 for guiding mainly the liquid chocolate A, and a nozzle provided with a discrete passage 12 for guiding mainly the liquid chocolate B. With this embodiment, a solidified chocolate (a solidified article) having a predetermined composite pattern may be produced simply by arbitrarily combining each parts, and each parts may be detached easily for cleaning, thus being remarkably advantageous. Further, the number of the outlets of each passage (discrete passages 11, 12 and uniting passage 21) may be decided as desired; the configuration of the outlet may be decided as desired, such as triangle, rectangle, oval, or the like; and the arrangement of the outlets may be decided as desired, for example, the outlets may be arranged alternately in circles, or in a staggered pattern, regularly, or irregularly.

Alternatively, the configurations of the porous nozzle provided with the discrete passages and the uniting nozzle provided with the uniting passage is not limited to the reversed truncated cone, and may be any desired shape such as a rectangular parallelepiped. Example 4 Another embodiment of the apparatus of the present invention is described with reference to Figs. 10 and 6. First, an apparatus for producing solidified chocolates wherein a predetermined amount of each of the liquid chocolate is intermittently supplied is described with reference to the drawings. The apparatus for producing solidified articles may be used for producing covered solidified chocolates having the liquid chocolate C accommodated inside and the predetermined composite pattern formed of the two kinds of liquid chocolate A, B (viscous fluids) which are distinct from each other at least in color covering the liquid chocolate C. The apparatus is mainly composed of: a depositor (not shown) for intermittently supplying a predetermined amount of the liquid chocolate A to C; a porous nozzle 50 provided with a plurality of discrete passages 51 to 53 for separately guiding each of the liquid chocolate A to C; a uniting nozzle 60 provided with a uniting passage 61 communicating with the discrete passages 51 to 53, collecting the streams of the liquid chocolate A to C guided by the discrete passages 51 to 53, and intermittently discharging a predetermined amount of the liquid chocolate A to C; and a conveyer 30' for receiving and transferring the predetermined amount of the liquid chocolate A to C intermittently discharged from the outlet 61a' of the uniting passage 61.

Further, timing for discharging each of the liquid chocolate A to C from each of the discrete passages is controlled at the depositor such that discharging of the liquid chocolate A and B from the discrete passages through the outlets 51a' to 51h', 52a' to 52h', respectively, start generally simultaneously, but discharging of the liquid chocolate C through the outlet 53a' starts later and stops earlier than the discharging of the liquid chocolate A and B, and this timing is maintained. The plurality of discrete passages 51 (Fig. 6(b)) penetrating the porous nozzle 50 guide the liquid chocolate A. The discrete passages 51 are provided with inlets 51a to 51h for receiving predetermined amount of the liquid chocolate A measured by the depositor in advance, and outlets 51a' to 51h' for discharging the liquid chocolate A received through the inlets. The plurality of discrete passages 52 (Fig. 6(a)) penetrating the porous nozzle 50 guide the liquid chocolate B similarly to the discrete passages 51. The discrete passages 52 are provided with inlets 52a to 52h for receiving predetermined amount of the liquid chocolate B measured by the depositor in advance, and outlets 52a' to 52h' for discharging the liquid chocolate B received through the inlets. The outlets 51a' to 51h' of the discrete passage 51, and the outlets 52a' to 52h' of the discrete passage 52 are arranged alternately in circles in a predetermined plane facing the conveyer 30'. The single discrete passage 53 penetrating the center of the porous nozzle 50 guides the liquid chocolate C, and is provided with an outlet 53a for receiving predetermined amount of the liquid chocolate C measured by a depositor in advance, and an outlet 53a' for discharging the liquid chocolate C received through the inlet 53a to the unit mold 70. With this structure, the liquid chocolate A and B are discharged through the outlets 51a' to 51h' and 52a' to 52h' arranged as desired into the unit mold 70 in a predetermined state, and the liquid chocolate C is discharged into the center thereof. The nozzle for separately guiding each of the liquid chocolate A to C may be a nozzle wherein the liquid chocolate A to C are guided by additional discrete passages branched upstream of the discrete passages 51 to 53 of the porous nozzle, or a porous nozzle wherein the discrete passages 51 to 52 themselves are branched (Figs. 7(a), 7(b)) as described above, in place of the porous nozzle 50. The uniting nozzle 60 communicating with the outlets 51a' to 51h', 52a' to 52h', 53a' of the discrete passages 51 to 53 has a contour of a reversed truncated cone having a tapered surface as shown in Fig. 5(b). The uniting nozzle 60 receives the streams of the liquid chocolate A to C discharged from the discrete passages 51 to 53 through the outlets 51a' to 51h', 52a' to 52h', 53a' via an inlet 61a, collects the received streams of the chocolate A to C together by a uniting passage 61, and discharge the chocolate A to C through an outlet 61a' provided at the lower end of the uniting nozzle 60, thereby guiding the chocolate A to C onto the conveyer 30'. The uniting nozzle for guiding the liquid chocolate A to C discharged from the porous nozzle onto the conveyer 30' may be other uniting nozzles 80 as shown in Figs. 8(a), 8(b) as described above, in place of the uniting nozzle 60. By the uniting nozzle, the streams of the liquid chocolate A to C discharged from the porous nozzle 50 in a predetermined state may be merged into a predetermined collected state for discharging therefrom. In molding the liquid chocolate A to C in the unit mold 70 in this Example, discharge of the liquid chocolate C is controlled to start later and stop earlier than the discharge of the liquid chocolate A and B, so that the liquid chocolate A and B accommodate and cover the liquid chocolate C, and the liquid chocolate C is finally covered by the liquid chocolate A and B completely on the conveyer 30'. As described above, according to the apparatus, the predetermined amount of each of the liquid chocolate A to C measured by the depositor (not shown) in advance is intermittently supplied, received separately through the inlets 51a to 51h, 52a to 52h of the discrete passages 51 to 53, discharged through the plurality of outlets 51a' to 51h', 52a' to 52h' arranged alternately in circles in a predetermined plane facing the conveyer 30'. The streams of the liquid chocolate A to C are collected by the uniting nozzle 60, and guided onto the conveyer 30'.

Then each of the predetermined amount of the liquid chocolate A to C intermittently supplied is guided by the discrete passages 51 to 53 of the porous nozzle 50, respectively, so that the liquid chocolate A and B are discharged through the outlets 51a' to 51h', and 52a' to 52h', respectively, arranged alternately in circles in the predetermined plane facing the conveyer 30', and the predetermined amount of the liquid chocolate C is guided by the discrete passage 53, so that the liquid chocolate C is discharged through the outlet 53a' surrounded by the outlets 51a' to 51h' and 52a' to 52h' and placed in the center thereof. In this process, the discharge of the liquid chocolate C is controlled to start later and stop earlier than the discharge of the liquid chocolate A and B. The streams of the liquid chocolate A and B discharged through the outlets 51a' to 51h' and 52a' to 52h' arranged alternately in circles and the stream of the liquid chocolate C discharged through the outlet 53a' surrounded by the outlets 51a' to 51h' and 52a' to 52h' are collected together by the uniting nozzle 60, and guided onto the conveyer 30' and solidify the liquid chocolate A to C, thereby producing the covered solidified chocolate (covered solidified article) having the predetermined composite pattern. In molding and solidifying the liquid chocolate A to C in the above process, a cooling machine may additionally be used, or a heating machine may also be used depending on the viscous fluid to be molded and solidified. In producing the covered solidified chocolates (covered solidified articles) with an apparatus of other embodiment of the present invention, the above procedure may be followed. Thus, the process is not described any further. In this apparatus, the porous nozzle 50 (Fig. 10(a)) may be replaced by other porous nozzles 50 as shown in Figs. 7(a) and 7(b) as described above. Details of the other porous nozzles as shown in Figs. 7(a) and 7(b) are as described above, thus they are not described any further.

The apparatus for producing solidified articles wherein the liquid chocolate is intermittently supplied in a predetermined amount has been described. Next, an apparatus for producing solidified articles wherein the liquid chocolate is continuously supplied in a predetermined ratio will be described with reference to the drawings. This apparatus for producing solidified articles may be used for producing covered solidified chocolates having the liquid chocolate C longitudinally extending as a central axis and the predetermined composite pattern formed of the two kinds of liquid chocolate A, B (viscous fluids) which are distinct from each other at least in color surrounding the liquid chocolate C. The apparatus is mainly composed of: a pump for high viscosity fluid (not shown) such as a gear pump or a snake pump for continuously supplying the liquid chocolate A to C in a predetermined ratio; a porous nozzle 50 provided with a plurality of discrete passages 51 to 53 for separately guiding each of the liquid chocolate A to C; a uniting nozzle 60 provided with a uniting passage 61 communicating with the discrete passages 51 to 53, collecting the streams of the liquid chocolate A to C guided by the discrete passages 51 to 53, and continuously discharging the liquid chocolate A to C at a predetermined ratio; and a conveyer 30' for receiving and transferring the liquid chocolate A to C continuously discharged at the predetermined ratio from the outlet 61a' of the uniting passage 61. In this embodiment, there is also provided a mechanism for rotatably driving the porous nozzle 50 and/or uniting nozzle 60 in one direction such as clockwise as shown by the arrow X, or counterclockwise as shown by the arrow X', or in reciprocating rotation as shown by the arrow Y in Figs. 10(a) and 10(b), around an axis perpendicular to the plane wherein outlets 51a' to 51h' and 52a' to 52h' are arranged. The plurality of discrete passages 51 to 53 (Figs. 6(a) and 6(b)) penetrating the porous nozzle 50 separately guide each of the liquid chocolate A to C. Each of the liquid chocolate A to C is continuously supplied by a pump for high viscosity fluid at a predetermined ratio. Therefore, each of the liquid chocolate A, B is discharged in a predetermined state through the outlets 51a' to 51h', 52a' to 52h' arranged in a desired arrangement onto the conveyer 30', while the liquid chocolate C is discharged through the outlet 53a' so that it extends longitudinally as a central axis surrounded by the liquid chocolate A, B. The porous nozzle for separately guide each of the liquid chocolate A to C may be a nozzle wherein the liquid chocolate A to C are guided by additional discrete passages branched upstream of the discrete passages 51 to 53, or a porous nozzle wherein the discrete passages 51 to 53 themselves are branched (Figs. 7(a) and 3(b)) as described above, in place of the porous nozzle 50. The uniting nozzle 60 communicating with the outlets 51a' to 51h', 52a' to 52h' of the discrete passages 51 to 53 are the same as described above. The uniting nozzle 60 for guiding the liquid chocolate A to C discharged through the porous nozzle onto the conveyer 30' may be replaced by other nozzles 80 as shown in Figs. 8(a) and 8(b) as described above. With the uniting nozzle, the streams of the liquid chocolate A to C may be collected together and merged in to a predetermined state for discharging therefrom. In this embodiment, the liquid chocolate A to C is poured onto the conveyer 30' so that the liquid chocolate C is surrounded by the liquid chocolate A and B to finally surround the liquid chocolate C extending longitudinally as a central axis by the liquid chocolate A and B on the conveyer 30'. As described above, according to the apparatus of the above embodiment, each of the liquid chocolate A to C continuously supplied in a predetermined ratio by a pump for high viscosity fluid (not shown) such as a gear pump or a snake pump is received through the inlets 51a to 51h, 52a to 52h of the discrete passages 51 to 53 of the porous nozzle 50, and discharged through the plurality of outlets 51a' to 51h', 52a' to 52h' arranged alternately in circles in a predetermined plane facing the conveyer 30'. The streams of the liquid chocolate A to C are collected together by the uniting nozzle 60, and guided onto the conveyer 30'. For producing covered solidified chocolates (covered solidified articles) having the liquid chocolate C extending longitudinally as a central axis and a predetermined mingled composite pattern formed of two kinds of liquid chocolate A, B (viscous fluids) surrounding the liquid chocolate C, first each of the liquid chocolate A to C is continuously supplied at a predetermined ratio by a pump for high viscosity fluid (not shown), and guided separately through the discrete passages 51 to 53 of the porous nozzle 50. Then each of the liquid chocolate A to C continuously supplied is guided by the discrete passages 51 to 53 of the porous nozzle 50, respectively, so that the liquid chocolate A and B are discharged through the outlets 51a' to 51h', and 52a' to 52h', respectively, arranged alternately in circles in the predetermined plane facing the conveyer 30', and the predetermined amount of the liquid chocolate C is guided by the discrete passage 53, so that the liquid chocolate C is discharged through the outlet 53a' surrounded by the outlets 51a' to 51h' and 52a' to 52h' and placed in the center thereof. The streams of the liquid chocolate A and B discharged through the outlets 51a' to 51h' and 52a' to 52h' arranged alternately in circles and the stream of the liquid chocolate C discharged through the outlet 53a' surrounded by the outlets 51a' to 51h' and 52a' to 52h' are collected together by the uniting nozzle 60, guided onto the conveyer 30', solidified, and cut into pieces, thereby producing the covered solidified chocolate (covered solidified article) having the liquid chocolate C extending longitudinally as a central axis and the predetermined composite pattern formed of the liquid chocolate A, B surrounding the liquid chocolate C. In molding and solidifying the liquid chocolate A to C in the above process, a cooling machine may additionally be used, or a heating machine may also be used depending on the viscous fluid to be molded and solidified. In producing the covered solidified chocolates (covered solidified articles) with an apparatus of other embodiment of the present invention, the above procedure may be followed. Thus, the process is not described any further. In the apparatus of this embodiment, the porous nozzle 50 (Fig. 10(a)) may be replace by other nozzles 50 as shown in Figs. 7(a) and 7(b) as described above. Further, in the apparatus of this embodiment, the uniting nozzle 60 (Fig. 10(b)) may be replaced by other uniting nozzles 80 as shown in Figs. 8(a) and 8(b) as described above. In the above embodiments, the porous nozzle 50 has been described as having the discrete passages 51 to 53 for separately guiding each of the liquid chocolate A to C integrally formed therein, but the porous nozzle of the present invention is not limited thereto. For example, the porous nozzle may be an assembly of a plurality of parts such as a nozzle provided with a discrete passage 51 for guiding mainly the liquid chocolate A, a nozzle provided with a discrete passage 52 for guiding mainly the liquid chocolate B, and a nozzle provided with a discrete passage 53 for guiding mainly the liquid chocolate C. With this embodiment, a covered solidified chocolate (a solidified article) having a predetermined composite pattern may be produced simply by arbitrarily combining each parts, and each parts may be detached easily for cleaning, thus being remarkably advantageous. Further, the number of the outlets of each passage (discrete passages 51 to 53, 82 and uniting passage 61, 81) may be decided as.desired; the configuration of the outlet may be decided as desired, such as triangle, rectangle, oval, or the like; and the arrangement of the outlets may be decided as desired, for example, the outlets may be arranged alternately in circles, or in a staggered pattern, regularly, or irregularly.

The accommodating portion 72' may be a mold representing a desired article, or a mold of any configuration. Further, the composite pattern to be formed with the solidified chocolates (solidified articles) may also be controlled by changing the point in the accommodating portion 72' of the conveyer 70' on which the liquid chocolate A, B (viscous fluids) falls which is finally discharged through the outlets disposed facing the conveyer. Alternatively, in the porous nozzle 50, the discrete passage 53 may be branched, and a portion of the liquid chocolate guided by the discrete passage 53 may be discharged for use as the viscous fluid for forming the composite pattern. Alternatively, the configurations of the porous nozzle provided with the discrete passages and the uniting nozzle provided with the uniting passage is not limited to the reversed truncated cone, and may be any desired shape such as a rectangular parallelepiped.
