Title: Improvements in the manufacture of margarine
Inventor: WILSON ARTHUR DACRE
IPC: A23D7/05
Filed: 1948-04-01
Abstract: 650,481. Margarine. LEVER BROS. & UNILEVER, Ltd. April 1, 1948, No. 9206. [Class 84] A continuous process for manufacturing margarine comprises the steps of cooling and agitating a stream of liquid fat so as to separate higher melting point glycerides therein as crystalline particles, mixing the fat with the aqueous ingredients in the desired proportions for producing margarine and subjecting the resultant mixture to continuous rapid chilling and emulsification. The cooling and agitating may be carried out prior to or after mixing the fat with the aqueous ingredients. As shown, liquid fat from a reservoir 1 is drawn into a cooler 35 consisting of four series of connected tubes 7 (two only shown) each surrounded by a water or brine jacket 8 and fitted with a shaft 9 carrying helical scrapers 10 and then through a pre-crystallizing cylinder 12 in which an axial shaft 13 carrying a row of radial rods 14 helically arranged through 120 degrees and intermeshing with rods 15 attached to the wall by a pumping device 17 and becomes mixed with the aqueous ingredients drawn by a pumping device 20 from the reservoir 2 in correct proportions and passes into a Votator 22 where it is rapidly chilled and emulsified after' which it passes into a large tube 24 fitted with wire-mesh screens 25 in which crystallization of the fat is completed. In a modification, Fig. 2 (not shown), arrangements are made so that part only of the fat passes through the cooler 35 and precrystallizing cylinder 12 whereafter this part is mixed with the uncooled part and passes through an additional precrystallizing cylinder 12<SP>1</SP> and continues as above. In a further modification, Fig. 3 (not shown), 'the.cooler 35 is dispensed with and the arrangement is such that some of the chilled and emulsified material from the Voltator 22 is bled off and fed to the uncooled mixture of fat and ingredients to cool it. The chilled and emulsified material before entering the tube 24 may be homogenized in any suitable manner, for example, by passing it through an apparatus as described in Specification 650,482. Examples of compositions are given. Specification 590,935, [Group XVIII], also is referred to.

Abstract: 1,104,625. Cyclone separators. ESCHER WYSS A.G. 5 March, 1965 [6 March, 1964]. No. 9554/65. Heading B2P. [Also in Division F4] A heat exchanger comprises two or more series-connected, superimposed cyclones 27, Fig. 7, in which, repeatedly, a gas stream is brought into contact with material in the form of dust or granules, e.g. raw cement meal, and then separated from it, a gas discharge pipe 6 of a preceding cyclone merging into a gas supply duct 5 of a succeeding cyclone. The material is first fed into the gas supply duct 5 of the uppermost cyclone through a pipe 26 having a lower portion 33 attached to an upper portion by means of a bellows 37 so that when there is sufficient material in the pipe the lower portion moves downwardly to uncover ports 36 for the material to enter the duct 5. The material is carried upwardly with gas discharging from the preceding cyclone and the mixture passes between non-radial, whirl-producing duct elements 10, Fig. 2, so as to be directed helically downwards in a separating zone 8. Clean gas leaves the zone 8 at 9 through passages 11 formed between the elements 10. The cyclone casing may 'be surrounded by a jacket 32 through which heat-exchange gas is fed under pressure to enter an annular chamber 29 and pass therefrom through a porous bottom plate 28 of the cyclone so as to keep the separated material which has collected thereon in a fluidized state to facilitate its discharge via another pipe 26 through which the material is led to the gas supply duct 5 of the preceding cyclone. Material is prevented from depositing in the pipes 36 by means of blasts of compressed air fed through pipes 38, 39 having opening at 40, 41. In a modification, Figs. 1 and 6 (not shown), the jacket around each cyclone is dispensed with and the porous bottom is replaced by a conical plane bottom having a material discharge pipe connection (7) which is connected via an external pipe (26) to the gas supply duct (5) of a preceding cyclone.
