Abstract
486,832. Solidifying liquids by cooling. CES. FUR LINDE'S EISMASCHINEN AKT.- GES., and KRAUSE, G. A. Aug. 27, 1937, No. 23526. Convention date, Sept. 25, 1936. [Class 29] In a process for concentrating aqueous solutions, e.g. fruit juices, milk, and meat extracts, by freezing out a part of the water and subsequently separating the ice from the solution, the freezing is effected at progressively diminishing temperatures. The temperature may be reduced in steps or continuously. Thus, orange juice having a 45 per cent concentration of dry or solid substance may be converted into a solution having a concentration of 60 per cent by pouring the solution into an annular cell, as described in Specification 429,474, and immersing the cell first in a brine bath having a temperature of about - 14‹ C., then in a bath at a temperature of - 20‹ C. and finally in one at a temperature of - 26‹ C. The freezing temperature may be reduced at a rate proportional to the fall in the ice precipitation temperature due to increasing-concentration.
