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.
