Title: Improvements in and relating to the desiccation of solutions at low temperatures
IPC: F26B5/06
Filed: 1941-12-18
Abstract: 552,821. Drying solutions by freezing. McFARLANE, A. S. Dec. 18, 1941, No. 16326. [Class 29] In the drying of solutions, such as milk and other food, by freezing followed by evaporation of the ice therefrom under vacuum, the solutions are frozen on to metallic surfaces which are heated by warm refrigerant to assist in the evaporation of the ice without melting it, and the water vapour is condensed as ice on cold surfaces. In the system shown brine or like medium circulated by a pump through a pan P for freezing the solution 6 is cooled by the evaporated 5 of a compression refrigerating machine including a compressor 2, condenser 3 and expansion valve 4. Another machine comprises a compressor 9 and alternative condensers 8 and 18. When the frozen solution is to be heated the compressed gas flows through the condenser 8 in thermal contact with the brine and frozen solution, and through an expansion valve 10 to an evaporator 11 on which the vapour from the ice resolidifies. The refrigerant vapour may return from evaporator 11 direct to the compressor 9 or may first pass through an interchanger coil 13 to assist in cooling the brine. When a fresh charge of solution is to be frozen the compressor 9 delivers to the independent condenser 18, an expansion valve 19 and the coil 13, now serving as the evaporator. In a modification a single compressor is used, and diversion from one condenser and evaporator system to the other is effected by actuation of the valves by a solenoid controlled by a thermal element sensitive to brine temperature. In a further modification, the solution is frozen on to a hollow plate immersed in it in a pan having a jacket traversed by evaporating regrigerant, the plate being cooled by the brine. The compressed gas is condensed in a coil in the brine tank. Specifications 450,145 and 539,477 and U.S.A. Specifications 1,970,956 and 2,066,302 are referred to.

Title: Improved manufacture of pressed yeast
IPC: C12N1/18
Filed: 1923-06-26
Abstract: 203,300. Klein, E. Aug. 29, 1922, [Convention date]. Yeast; fermenting.-Yeast is cultivated in a medium which has been deprived of the substances most easily attacked by cultivating yeast therein and is then further cultivated in a medium containing these substances. At least 10 per cent of the sugars utilized should be used in the second stage. Fresh wort is added to the exhausted wort used in the first stage and the fermentation carried to the utmost extent, when the yeast is separated and placed in fresh wort, or fresh wort may be added to the mixture, though this is less efficient. The yeast is removed when in its best condition and the spent wort used for the first stage of the cultivation of another lot of yeast. In order to utilize both the carbon and the nitrogen of the wort, two worts may be used, one specially rich in carbon, such as corn heated under pressure and saccharified with a small amount of malt, and the other specially rich in nitrogen, such as extract of malt sprouts with ammonia compounds. These worts are supplied alternately to the yeast, the cultivation being pushed as far as possible between each addition and the next. Different modifications of the process are described for producing more or less alcohol in addition to the yeast. The more alcohol is required the more fresh material should be mixed with the spent liquid used in the first stage. The Specification as open to inspection under Sect. 91 (3) (a) states that in cultivating yeast phosphorus compounds may be added' before the conversion of the sugar and ammonia compounds after. This subject-matter does not appear in the Specification as accepted.
