Puffed Rice Making Machine

Puffed grains are grains that have been expanded ("puffed") through processing. They have been made for centuries with the simplest methods like popping popcorn. Modern puffed grains are often created using high temperature, pressure, or extrusion.

A puffed rice making machine, also known as a puffing machine, is designed to rapidly heat and expand rice grains, transforming them into a light, crispy, and puffed-up snack. These machines typically use a pressure vessel, hot sand, or extrusion methods to achieve this transformation.
High pressure puffed grain is created 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.
