STIRRING DEVICE FOR COOKING POTS, ETC

Abstract: Easily manageable stirring device for cooking pots provided with a drive motor unit and stirrer means. The drive motor unit is supported by a beam structure diametrally disposed above the cooking pot (5) and intended to be secured to the upward-facing edge surface (6) of the cooking pot and supported along its two long edges by means of hinges (13, 14) two lid halves (10, 11) for the cooking pot.

Description: STIRRING DEVICE FOR COOKING POTS, ETC Mach ne-powered s rrers are nowadays generally used together with cooking pots for large catering establishments. Several different types of such stirrers, based on different principles, are currently available on the market. It has been found, however, that the stirr.ers have not actually been widely used in practice, probably because they have been d fficult and cumbersome to handle. In point of fact, it has been found that it is difficult to get at the interior of the cooking pot, the reason being that the stirring device has ' been in the way and/or that the lid of the cooking pot has been in the way. The present invention affords a simple and effective solution to problems of t is nature. In addition to the stirring device according to the invention being extremely practically supported, it also permits easy access to the interior of the coo ing pot. The characteriz ng features of the invention are evident from the accompanying patent claims. One embod ment of the invention w l l now be described in more detail and with reference to the accompanying drawings where Fig. 1 shows a section of a side view of a cooking pot arrangement in which the invention is appl ied and Fig. 2 shows the device according to Fig. 1 from above, wi h one of the covering l ids of he cooking pot partly cut away. The dev ce llustrated consists of two stands 1, 2, supporting a tiltable cooking pot 5 by means of journals 3, 4. Disposed diametrally across the cooking pot 5 on its upper, ring-shaped edge 6 s a beam structure 7 supporting , drive motor unit consisting of a gear housing 8 and a motor support one ssttiirrrreerr ppaarrtt JU,, 3 j1i.. T ihnee mmeeans JU and Ji are supported byy tthhee ccrroossss--bbeeaarr:s 27. They are detachable from cross-beams 3 "■> .2?, 33 b hyv m meoaannse- 0 f screw jo nts 35, 36. OMPI al so clearly evident fro F . 1 , the stirring means 30, 31 are elaborated as frame open ngs suppor ing crosswise- disposed plates 41 and 42 respectively. These plates a r e al so arranged offset so that each of them infl uences its ow portion of the mass during the rotation at the same time as turbulence s accompl ished. The said crosswise plates 41 a 42 can per se be positioned at an angle in relation to the direction of rotation n order to attain the desired direction co posant of the stirred mass . The adjustability can be performed so that they a re preset prior to each stirring task, depending on factors such as the viscosity o the mass . The device functions in the following manner. When the means 19 with its scraping means 21-25 moves in the direction of the arrow 39, a carrying force is exerted on th mass in the d rection of the said arrow 39. At the same time, a motional composaπt directed towards the i-.side of th pot will aris-e through the obliquity of the scraping means 21-25. Means 30 and 31, n contrast, move in the direc on of the arrow 40, i .e. in the opposite direction,, so that turbulence occurs when the flows of l quid in opposing directions meet. In practice, this means that the whole of the l quid mass, largely through the opposing d rect ons of the influencing forces of the two stirring means, will not part cipate n the rotation. The means 22, 23 and 24 acting along the bottom will , through the obl ique scraper means, cause mass contained therein to move upwards towards the central parts of the pot This internal motion is deflected by the means 30, 31 so tha a radial d rect on of mo on is i parted to the said part of the mass. The movement of the mass will thus take place essential ly in a radial plane in the cooking pot, so that mass located at the bottom w ll be pressed up towards the central sections and be thrown out by the means 30 and 31 towards the periphery of the pot, where they will be hit by an oppcsiπgly directed notional composant accompl ished by OMPI the means 19 with the scrapers 21-25, whereby turbulence is formed . This design demonstrates a plural ity of practical advantages. The fixed beam structure 7 across the pot serve in a stable manner as fastenings for the openable lids 10 ' an 11. Through the shown openabil ity, it is easy to get at the interior of the pot and also easy to get at the stirring means for inspection and dismantling. As evident from Fig. 2, the lid 10 is provided with a number of holes 43 along on peripheral edge for pouring off liquid from the cooking mass. In order to prevent this lid from opening, a locking arm 44 is provided • wh ch can mesh with the run-off flange of the pot . The gear house arrangement is appropriately such that the pinions incorporated therein can be altered so that different relative speeds can be obtained between means 30, 31 and 19-25. The gear housing is appropriately -.rovided with a variatcr for adjustment of the speed and an actuator for this is disposed on the gear housing and has reference numeral 46. In speed regulation, the speed o * f both stirring means will be regulated proportionally as the gear ratio is f xed . The entire cooking pot can be tilted to empty its contents around the journals 3, 4 in a known manner. It is not necessary for the stirring means to have the illustrated for * - ** within the inventive concept. These can be varied in numerous ways. "gJREX > OMPI
