Abstract

1448762 Drying materials SINTAB SWEDINVENTOR AB 17 Jan 1974 [18 Jan 1973] 02144/74 Heading F4G The invention relates to a method of and apparatus for drying material in liquid, granular, powder or plastic form. The method comprises the steps of feeding a plurality of heated heating elements 55 of high specific heat, e.g. 0À9 cals./grm.‹ C. and the material 25 to be dried together into a tank 1 set under subatmospheric pressure, e.g. 10 mm. of mercury, discharging the mixture of material and elements when the material is dry and separating the material from the elements. As shown the elements 55 are fed from a hot water heat exchanger 5 to a compartment of a primary tank 2 while the material 25 is fed to another compartment thereof through respective valves 58, 26. Before the mixture is fed through a valve 16 to the tank 1 the primary tank 2 is evacuated. In the tank 1 water vapour driven from the material is condensed by sprays 65 of cold water in a compartment at the upper end of the tank. The dried material and elements pass into a secondary tank 3 in which they are separated by a vibrating screen 74.
