Gun Puffer

A grain puffing machine is a portable, non-flammable machine that removes impurities and potential from the grain. It is used to expand cereal grains and expandable semi-finished products. The machine works by placing whole grains under high pressure with steam in a containment vessel. When the vessel’s seal is suddenly broken, the entrained steam then flashes and bloats the endosperm of the kernel, increasing its volume to many times its original size.
