Abstract
Soap slurries, fruit juices and other liquids are concentrated by evaporation without foaming by feeding the material into a tortuous flow path of relatively narrow cross-section elongated in a direction lateral to the flow of the material, the flow path having preselected variations in its cross-section, passing the material through the flow path while supplying heat to release vapour from the material, the rate of feed and the heat supplied being so as to obtain a high rate of evaporation and a high velocity of the mixture through the flow path thus inhibiting deposition of concentrate upon the surfaces which defines the flow path. Reference is made to the removal of solvents from oils, and the separation of alcohol from water. In a preferred embodiment using a plate-type evaporator the material to be evaporated is pumped from a supply tank 10 via line 14 into the evaporator through an inlet 16. The evaporator is formed from a plurality of plates 17 arranged in spaced relationship by gaskets 18 held together in frame 15 by a compression means 19. The spaces between the plates alternately form flow channels for the liquid-to-be-evaporated and the heating-medium. The first plate of each channel for the liquid being evaporated has an inlet port 21 and the next adjacent plate thereto has an outlet port 22. The number of flow channels for the liquid increases, in the direction <PICT:0935542/III/1> of flow, from one to four. Preferably the ports increase in cross-sectional area towards the final outlet port which exits to a line 24 which conveys the product to a separator 25 which has a vapour overhead take-off line 26 and a draw-off pipe 27 for removing the concentrate product. In another embodiment, the mixture of liquid and vapour can be tapped off from an intermediate channel and led to a separate separator. The separated liquid can then be fed back to the next channel; and the separated vapour can be used to provide heat for evaporation in the second stage.
