HEAT TREATMENT METHOD AND APPARATUS FOR GRAINS

摘要

A method for rapidly heat treating a cereal such as rice in at least two cyclones wherein the cereal is contacted for 10 to 15 seconds with hot gas at a temperature of 400 DEG to 600 DEG C. Substantially all the heat treatment occurs in the cyclones which provide conditions of extreme turbulence enabling the vaporization of water in the cereal to produce a substantially uniform microporous product. Quick cooking rice cookable in about six minutes may be produced very economically.
