    Abstract: 1,139,075. Filter cake demoisturing. FARBWERKE HOECHST A.G. 11 Feb., 1966 [12 Feb., 1965], No. 6163/66. Heading C4P. [Also in Division B1] Azo dyestuffs, in the form of cake from a filter press, are further demoistured by kneading in a container 3 having a pervious surface 2 on which a stationary layer of dyestuff is maintained 0À5 to 8 mm. thick by suitable spacing of roll 1, while maintaining a pressure difference across the said layer to expel liquid therethrough, the kneading consisting of alternate periods of fast and slow action with a speed ratio in the range 1/3 to 1/20 between them until no more liquid is obtained. The roll 1 describes a sun-and-planet movement round container 3, the two rotations being independently driven by variable speed motors (speeds given). Dyestuff is delivered by inlet 6, which may be subsequently used to apply pressure gas, and outlet 16 is connected to an air suction pump. Treated dyestuff is discharged by screw extrusion press 4, 5, whose tapered outlet may prevent discharge of excessively wet material. The apparatus may be used to treat the dyestuffs further, by adding washing water or other liquids able to displace the residual liquid, mixing therewith and again demoisturing. The spacing between roll 1 and fine mesh fabric (30 microns) or perforated surface 2 is adjusted by raising and lowering the drive-shaft 12, by nuts 14, 15.

    Abstract: The properties of dried microbial biomass are improved by a heat treatment at temperatures from 105 to 160 DEG C. When the lipids and nucleic acids are subsequently extracted, the products of the process show advantages in use, a reduced loss of protein, and a higher biological value.
