ABSTRACT:
A process for simultaneously atomizing, cooking, and drying a mixture of starch and water in the exhaust gas stream from a sonic pulse jet combustion engine is described. The process consists of preparing a mixture of a granular starch with water (preferably a starch cake), feeding the mixture into the exhaust pipe of the jet combustion engine, maintaining the resulting mixture of atomized starch, water, and hot gas in the exhaust pipe for a time sufficient to gelatinize and substantially dry the atomized starch, and recovering the pregelatinized starch powder by exhausting the mixture into a collection chamber supplied with a flow of air.
