The basic principle of extrusion machine and extrusion

  DATE:2016/06/24
  Extrusion technology - continuous extrusion cooking process is the core equipment extruder. Extruder having a compression, mixing, kneading, melting, puffing, molding, and other functions.

    The cavity of the extruder can be divided into 3-5 areas, each may be heated by steam or electric, can also be heated by friction extrusion, so as to achieve the purpose of cooking materials, high-temperature material in the cavity, under the influence of high pressure, starch gelatinization, protein denaturation. When the material through the extruder cavity districts when soluble flavor and coloring materials can be injected into the cavity through the material being under the influence of high pressure. At the end of the extrusion cavity, the molten material by the action of high pressure through the extrusion die orifice of the template, because of a sudden drop in pressure, the rapid expansion and loss of water vapor, so that the product to form a porous structure, and then the material is extruded rotary knife cut to the size of the product.

      Breakfast cereal production in the most commonly used is a single-screw extruder and a twin-screw extruder, and a twin-screw extruder has more advantages compared with single-screw extruder, single screw extruder because the particle size of the material water requirements, demanding components and materials prone to back, screw easy to wear and other issues.
