Abstract

952,920. Drying liquid foods. VICKERS-ARMSTRONGS Ltd. Nov. 2, 1962 [Nov. 10, 1961], No. 40342/61. Heading A2D. For drying foods ordinarily liquid or semi-liquid, e.g. fruit juice or egg, in frozen form there is employed the apparatus of Fig. 1 comprising a tower 1, vacuum equipment 12 for evacuating the tower, a hopper 2 at the top of the tower for supplying the material to be dried, an outlet 3 for the dried material, inclined plates 14 arranged one above the other in the tower so that material falls down the tower in a zig-zag course, and means for heating to evaporate water from the material as it falls, e.g. electrical heating of the plates 14. The plates may be vibrated to facilitate flow of material. A rotary valve 5 meters material from the hopper into the tower, and a rotary valve 7 the dried material from the tower into the outlet 3. Crushed or chipped blocks of frozen food are fed into the tower, or unfrozen food is introduced as droplets which freeze by evaporation under the reduced pressure in the tower. Alternatively, the apparatus of Fig. 2 is employed to prepare droplets of frozen food, the food from a supply tank 25 being fed through warmed jets 23 into the top of a tower 18 supplied by a pipe 20 with cold air (-40‹C.), and the frozen droplets so formed being delivered by a conveyer 27 into the hopper 2.
