Abstract

739,288. Plate heat-exchangers. AKTIESELSKABET ATLAS. May 4, 1953 [May 3, 1952], No. 12367/53. Class 64 (3). Relates to a heat-exchanger as described in Specification 644,312, for heating or cooling viscous substances such as fatty emulsions &c., in which heating or cooling medium flows through stationary containers 1 while discs 12 bearing scrapers 23, Figs. 2, 3, rotate between the containers in spaces 11 through which the treated substance flows under pressure. In Fig. 2, three resilient scrapers 23 are indicated on each side of a disc 12. According to the invention, to avoid bending of the discs due to accumulation of viscous substance in front of the scrapers, there are projections 26 on one or both sides of the discs, the ends of which projections move very near to the walls 6 of the containers 1, and there are holes 25 in all or some of the scrapers. These holes and projections may be embodied in the upper discs 12 only where the viscosity has increased. The dished side walls 6 form the spaces 11 containing the discs 12. The heating or cooling medium enters an inlet on the lowermost container 1 and flows, by way of similar outlets and inlets 16, in series through the containers which are each divided into an upper and a lower compartment by a partition 14 having holes 15 near the middle and bearing ribs 18, e.g. forming spiral channels in which the medium flows. From the top container the medium flows out through a duct 17 formed by sections on each container. The viscous substance flows from an inlet 22 to an outlet duct 24 at the top, through each space 11 around each stainless-steel disc 12 and through central spaces in which rotate the hubs of the discs 12 where they are keyed to a shaft 10 driven by worm gearing 20. Cooling medium may be supplied to some containers 1 and heating medium to others.
