Description
Technical Field
[0001] This utility model relates to the field of spicy strip puffing processing technology, specifically a puffing device for spicy strip production. Background Technology
[0002] An extruder is a device used to process puffed foods, such as rice, corn, soybeans, and wheat. Its main working principle is the conversion of mechanical energy into heat energy; the heat generated by the machine's rotation cooks the food. The most obvious characteristic of puffed food is its increased volume. Extruders are versatile and widely used in feed, food, and industrial fields. Commonly used extruders include dry-process, wet-process, single-screw, and twin-screw extruders. For example, twin-screw extruders are typically used for dough puffing in spicy snack processing.
[0003] Existing dough puffing equipment and processes often employ a continuous, segmented feeding and extrusion processing structure, consisting of a feeding section, a compression section, and an extrusion section. The dough is gradually fed and pressurized to achieve a high-temperature and high-pressure processing effect. However, if the temperature in the first section of the dough does not reach the predetermined requirements and the mixing effect is poor, the dough may become sticky or even partially burnt in the extrusion section. In addition, the high temperature and high pressure in the extrusion section in existing processes also present technical challenges in how to dissipate heat from the high-temperature processing parts.

The mixing chamber is located above the extrusion chamber, so the heat is dissipated and exchanged from bottom to top. The preheated and mixed dough is fed to the twin-screw extruder through the feeding device, where it undergoes high-temperature and high-pressure extrusion processing. The dough is then discharged through a specific discharge mold at the extrusion outlet and finally transferred to the next processing stage by the feeding device.
