Description

Technical Field

[0001] The invention relates to the technical field of spicy strip puffing processing, and in particular to a puffing device for spicy strip production. Background Art

[0002] The extruder is a kind of equipment for processing extruded food, such as rice, corn, soybean, wheat, etc. in daily life. Its main working principle is to convert mechanical energy into thermal energy, and use the heat generated by the rotation of the machine to extrude and cook the food. The most obvious feature of the extruded food is that the volume becomes larger; the various functions of the extruder make it widely used in feed, food and industry. Commonly used extruders include dry method, wet method, single screw or twin screw and other main processing forms; among them, the dough extrusion used for spicy strips processing usually adopts twin screw extruder equipment.

[0003] For the existing dough puffing equipment and technology, a continuous whole-stage material transport and extrusion processing structure is often adopted, which is divided into a feeding section, a compression section and an extrusion section at a time. The dough achieves a high temperature and high pressure processing effect in the process of gradually feeding and pressurizing. However, once the temperature of the front section of the dough does not meet the predetermined requirements and the mixing effect is poor, it is easy to cause the dough to become sticky or even partially burnt in the extrusion section. At the same time, in the existing process, the high temperature and high pressure of the extrusion section will also bring about the technical problem of how to dissipate the high temperature of the processed parts.
