Description

Extrusion forming device for puffed particles

Technical Field

The utility model relates to a popped production field especially relates to a be used for popped granule extrusion device.

Background

Puffing, a processing method. The raw material is suddenly decompressed and expanded under heating and pressurization. After the starch-containing material is heated and pressurized, the external force and the heat source are suddenly removed, so that the starch-containing material is rapidly expanded. The extrusion puffing is that the material is sent into an extrusion puffing machine, and under the pushing action of a screw and a spiral, the material moves forwards in an axial direction. Meanwhile, due to the mechanical friction action between the screw and the material, between the material and the machine barrel and inside the material, the material is strongly extruded, stirred and sheared, and as a result, the material is further refined and homogenized. Along with the gradual increase of the pressure in the machine cavity, the temperature is correspondingly and continuously increased, the physical properties of the materials are changed under the conditions of high temperature, high pressure and high shearing force, the materials are changed into paste from powder, starch is gelatinized and cracked, protein is denatured and recombined, fiber is partially degraded and refined, pathogenic bacteria are killed, and toxic components are inactivated. At the moment when the pasty material is sprayed out from the die hole, under the action of strong pressure difference, the water is quickly vaporized, and the material is puffed to form a puffed product with a loose structure, multiple holes and crisp texture, so that the purpose of extrusion puffing is achieved.

When the existing materials are stirred and placed in a hopper for expansion treatment, the feeding pipe is often blocked. Meanwhile, the device is inconsistent with the heat generated by the friction in the material extrusion process and the heat carried by the material, so that the quality of the puffing is easily inconsistent.
