Abstract
In apparatus for drying heat-sensitive, atomizable materials, e.g. milk, fruit juices, aroma-rich extracts, in particle form produced either by pre-freezing liquid material in apparatus described with reference to Fig. 4 (not shown), or by delivery through atomizer or sprayer means 18 into a compartment 1 evacuated by a pump 9 and having a heat radiating wall 2, the particles fall by gravity through the chamber and are prevented from contacting the wall 2 by a mesh cylinder 10 coaxially mounted within the compartment. A vortex is formed within the compart ment by an agitator 14 with vanes 141 so that the vapours sublimed or evaporated from the particles are caused to flow through a vapour conduit leading to the pump 9 and the dried particles separated therefrom are removed through a valved base 5. A temperature sensing device41 may control the quantity of radiant energy and/or the speed of delivery of the particles to the apparatus as a function of the temperature of the vapour stream. A portion of the vapours from the conduit or condenser 8 therein is delivered by a blower 12 to the annular compartment lb formed between the wall 2 and cylinder 10 and into the compartment 1 to prevent particles contacting the wall 2. In a modification, Fig. 2 (not shown) the agitator 14 is replaced by tangentially introducing the vapours from the blower 12 and the radiant walls in the embodiments of Figs. 2 and 3 may have areas at different temperatures.
