Abstract

454,075. Solidifying liquids by cooling. GES. FUR LINDE'S EISMASCHINEN AKT.- GES., H÷llriegelskreuth, near M³nich, and KRAUSE, G. A., 16, Widenmayerstrasse, Munich, Germany. March 23, 1936, No. 8696. Convention date, March 26, 1935. Addition to 429,474. [Class 29] In the process according to the parent Specification in which a solution to be resolved by freezing one or more of its constituents is cooled in a mould until it is sufficiently frozen to be removed to a separator, such as a centrifuge, the optimum quantity of ice to be separated to give a resulting moulded body of ice and concentrate of sufficient mechanical strength to withstand centrifuging is determined from the relation Y=<n>#x,c where x and y are the percentage concentrations of the original solution and concentrate respectively, and n and c constants varying between 2 to 3À5 and 9 to 26 respectively. Solutions of low concentration are enriched by the addition of concentrate or dry substance prior to freezing out the water. The lower limit for the quantity of ice separated is determined by the stability of the ice skeleton and the upper limit by the pore dimensions in the skeleton which should not retard heat transference. Coffee extract, fruit juices and milk are referred to.
