Abstract
A popcorn processing machine has a heating chamber into which a measured quantity of raw corn kernels are fed in each operational cycle to be heated, agitated, and thus popped by only a hot air supplied under pressure as a whirling rising vortex, without the use of an oil, whereby greatly expanded puffs of popcorn of uniform quality are produced in a high yield and in a short processing time. The bottom of the heating chamber can be opened by a simple mechanism, whereby the popped popcorn product can be quickly dumped and the chamber bottom rapidly reclosed, the operational cycle time thereby being extremely short.
