Extruded food packaging machine is a special equipment for packaging extruded food, its working principle is to fill the food into the packaging bag through the feeding system, and then through the control system for automatic operation to complete the sealing and molding. It uses mechanical energy to heat energy to provide kinetic energy, usually using the extrusion of non-equidistant non-standard screw system to push the gas in the material to be discharged and quickly filled by the material. The material is subjected to shearing force in the bore and produces reflux, which increases the pressure, and then converts into heat energy through the friction of the material in the bore, making the material become a gelled state with fluidity. When the material is squeezed to the outlet, the pressure changes from high pressure to normal pressure instantly, and the temperature changes from high temperature to normal temperature instantly, resulting in the rapid evaporation of water from the organizational structure. With the friction between the screw and the bore, the material is fully mixed, squeezed, heated, glued and gelatinized, so that numerous microporous structures are formed inside, and then the puffed food can be formed by cutting and cooling through the cutting device.
Puffed food packaging machine has a wide range of applications in the production of puffed food, potato chips, nuts, candy, chocolate, frozen food, hot pot balls and other leisure food, while with the continuous upgrading and improvement of technology, it can also be used in medicine, chemical, pesticide and other industries of granular, flake, block and other solid materials packaging.
The advantage of extruded food packaging machine is high efficiency and fast, which can greatly improve production efficiency. However, please note that different types of puffed food packaging machines may have different characteristics and functions, and should be selected according to actual needs when purchasing.
