In recent years, puffed food has been favored by more and more consumers for its crispness and good taste. So, how are these delicious puffed foods produced? It turns out that the puffing machine is the necessary equipment for puffing in the food industry.

1. Principle and classification of extruder
An extruder is a device that uses high temperature and high pressure to expand, deform and sterilize substances. It is mainly composed of puffing pressure chamber, screw, electric control system and other parts. According to different fields of use, extruders can be divided into food extruders, chemical extruders, pharmaceutical extruders and feed extruders.
2. Application of puffing machine in food processing
puffed food
The most common puffed foods are rice crackers, popcorn, cheese balls, etc. In the puffing machine, through high temperature and high pressure, the processing raw materials such as corn and rice are expanded into a porous structure, so as to achieve the effect of crispness and good taste.
Puffed soy products
Puffed soy products refer to foods formed after processing soybeans and other beans, such as: textured soybean protein, vegetable silk protein, vegetarian meat protein, etc. The bean raw material can be matured and expanded by the puffing machine, making the food taste delicious, soft and delicious.
feed application
The extruder can also be used for various aquatic feeds such as floating, sinking, caching fish feed, crayfish feed, abalone and sea cucumber feed, ornamental fish feed, etc.
