Popcorn Processing Machine

Popcorn processing machine is a commonly used processing technology in the food industry with a wide number of applications. It is a processing system that utilizes a single screw or a set of screws to force food materials through a small opening. While food is being forced through the extruder, foods are cooked by the high pressure, high shear, and high temperature environment created by the screws, encased in the barrel. Upon exiting, materials often puff due to the release of pressure and conversion of water into steam. The entire process is continuous and capable of happening in less than a minute. The most commonly used extruders in the food industry include single-screw and twin-screw systems, with twin-screw systems more widely used because of their flexibility. A brief overview of extrusion processing systems is provided in this publication, including applications of extrusion in the food industry, different parts of the extruder, and the concept of extrusion as a multiple input and multiple output processing system. This publication serves as an introduction to the understanding of food extrusion processing.

Foods can be structurally complex, incorporating emulsions and mixing solids, liquids and gels into a single product.
Food extrusion is an established and highly versatile technique for producing food, feed, nutritional additives and flavors.
Extruders with varying dies are used to design and shape foods with high starch content such as pasta, cereals or
snacks, analogue meat products, and pet food, and to determine their final texture. In addition, extrusion enables a costeffective, continuous means of production with precise control for maintaining high product quality.
