The Working Principle Of The Extruder

The working principle of the extruder is actually relatively simple, in the overview of the extruder we have talked about, the extruder is the use of mechanical energy to heat energy to provide kinetic energy, usually the use of the extruder unequal non-standard spiral system extrusion propulsion, the gas in the material is discharged, and quickly filled by the material, the material is affected by the shear force and produces reflux, so that the pressure in the chamber increases, and then at the same time the mechanical energy is converted into heat energy through the friction of the material in the chamber, so that the material becomes a gelling state with fluidity. When the material is squeezed to the outlet, the pressure changes from high pressure to normal pressure instantaneously, from high temperature to normal temperature instantaneously, resulting in the rapid evaporation of water from the tissue structure, with the friction between the stack and the chamber to make the material fully mixed, extruded, heated, glued, gelatinized and produce organizational changes, the original structure is destroyed, so that countless microporous structures are formed inside, and then through the cutting device, the puffed food is formed by cutting and cooling.
