ABSTRACT:
A process and apparatus is provided for cooking or gelatinizing a material in an atomized state, so that there is obtained an easily dryable, uniform and finely-sized product. The material which is to be cooked is injected through an atomization aperture in a nozzle assembly to form a relatively finely-sized spray. A heating medium is also injected through an aperture in the nozzle assembly into the spray of atomized material so as to heat the material to a temperature effective to cook or gelatinize the material. An enclosed chamber surrounds the atomization and heating medium injection apertures, and defines a vent aperture positioned to enable the heated spray of material to exit the chamber. The arrangement is such that the elapsed time between passage of the spray of material through the chamber, i.e., from the atomization aperture and through the vent aperture, defines the cooking or gelatinization time of the material. The apparatus and process disclosed herein are particularly useful in preparing a novel uniformly gelatinized starch product, but also have utility in connection with cooking protein or other suitable materials.
