Entering The Puff Snack Food Production Line

The raw materials for making puffed food are mainly: corn flour, wheat flour and other grain flours.

1.The first step is to mix a certain proportion of water and raw materials in a powder mixer.
2.The second step is to convey the mixed raw materials to the puffer through the spiral.
3.The third step is to produce puffed food under high temperature and high pressure.
    When the material enters the puffer, it will first come to the screw extrusion system. When the screw rotates at high speed, with the help of a special spiral structure, it pushes the material forward in the barrel like a pair of powerful hands. In this process, strong friction occurs between the material and the screw, the inner wall of the barrel and itself, and this friction is converted into a large amount of heat energy.  At the same time, the external heating device of the machine is also working together to further increase the temperature of the material to a specific high temperature condition.
    The material under high temperature and high pressure is like a huge energy sealed. When it is pushed to the die head, due to the special design of the die head, the material is instantly released from the high pressure state to the normal pressure environment. This drastic change in pressure is like the instantaneous explosion of suppressed energy. The water in the material quickly vaporizes and expands, forming countless tiny bubbles, just like popcorn popping at high temperature. The originally tight material structure is quickly stretched, and the volume instantly increases several times, thus completing the puffing process.
4.The fourth step is to transport the puffed product to the oven through the elevator for drying.
5.The fifth step is to use the oven to dry the water contained in the puffed food, making the puffed food more crispy.
6.The sixth step is to transport the dried puffed food to the seasoning system through the elevator.
7.The seventh step is to season the product through the double rollers.
8.The eighth step is to cool the seasoned puffed food for easy packaging
9.The ninth step is to package the cooled product.

This is the entire production process of puffed food. We have a deep understanding of the puffed food production line from three aspects: the raw materials of the product, the production process of the product and the final product.
