Title: Method and apparatus for the concentration of liquid substances
Inventor: JR HARRY AUBREY TOULMIN
IPC: F26B5/06
Filed: 1952-10-29
Abstract: 727,918. Concentrating fruit juices &c. COMMONWEALTH ENGINEERING CO. OF OHIO. Oct. 29, 1952, No. 27197/52. Class 49. Concentration by freeze dehydration of liquid substances containing solids, especially fruit juices, is effected by supplying the liquid in the form of a thin layer on to the upper part of a moving refrigerated surface and collecting the concentrate at the lower part of the surface, the ice forming on the refrigeated surface being periodically removed. The liquid may be supplied over a series of the surfaces refrigerated to progressively decreasing temperatures. With the apparatus of the drawing, fruit juice is sprayed at 32 into the. top of a rotating, vertically-disposed drum 12 having a jacket 22 through which refrigerant fluid is passed to chill the inside walls of the drum to 25‹F. subjection of the juice to the freezing action of the drum walls being attained by adjustment of the rate of delivery of the juice and of the speed of rotation of the drum. The juice from the discharge opening 36 falls on to an inclined perforated plate 38, ice being deflected thereby into a tank 43 and concentrated juice flowing through the perforations into a tank 42. Juice from the drum 12 is pumped from'the tank 42 to a drum 12a, similar to the drum 12 but operating at 10-15‹F. for further ice removal, and juice from the drum 12a is pumped to a drum 12b, similar to the drum 12 but operating at 3-5 ‹F. for still further ice removal. Periodically the ice depositing in each drum is removed, the drum being quickly warmed to cause the ice to fall off, or to be easily cracked off.
