The corn flake produced by the corn flake production line is a kind of brittle food, with good rehydration ability, non-rotten external flushing, smooth taste and rich grain flavor. Its main raw material is corn flour, and added sugar, a variety of vitamins, minerals mixed raw materials, after adding a certain amount of water is fully kneaded, ripening, molding, pressing and baking flavoring made of thin slices.
The corn flake production line adopts twin screw extruder, whose working principle is that under high temperature and high pressure, the water contained in corn kernels absorbs energy and vaporizes, and penetrates and cuts through the interior of corn molecules forcibly. Before reaching the homogenization stage, the corn flour gradually changes from solid state to viscous state. Viscous flow of corn protein molecule in the homogenization section to continue its protein denaturation process, and have been successively extrusion, when subjected to a sudden drop in temperature, swelling rapidly into protein molecules within the water molecules, vaporization, and “Fried” surrounded by its material, end finally degeneration process, make the goods together with many pores of porous material – puffed corn ball,
The expanded corn balls are then cooled and rolled into corn flakes.
Corn flake production line is not a single equipment, but by mixing powder – screw conveyor – twin screw extruder – vibration cooler – air feeder – tablet press – hoist – oven – sugar spraying – cooling – packaging and other equipment. Here I will introduce you one by one:
1, Mixing machine: mixing raw materials, auxiliary materials and water and other materials, moderate speed, uniform mixing
2, Screw conveying: the use of screw mechanism to lift the raw material to the twin screw host feeder.
Double screw extruder: this machine is composed of feeding system, extrusion system, rotary cutting system, heating system, transmission system and control system. Using screw extrusion technology, using high temperature and high pressure to mature the material and puffing molding, one-time completion. The host adopts frequency conversion speed regulation to ensure the stability of the production process.
3, Vibration cooling: used for the initial cooling of the product, the product out of the last equipment evenly distributed to the next equipment.
4. Air feeder: used to transport puffed food to the next equipment.
5. Tablet press: Used to press semi-finished products into sheet products.
6, Lifting machine: used to lift the product to the oven.
7. Oven: used to dry and dehydrate the semi-finished products produced by belt drying device. A certain number of heating devices are installed in the oven to dry the semi-finished products by electric heating.
It is a commonly used drying dehydration device for extruded products.
8. Sugar spraying machine: the corn chip production line is used to adjust the taste of the product, the front section roller is used for seasoning, and the rear section roller is used for oil spraying, so the seasoning and oil spraying are operated separately, and the seasoning quality of the product is improved a lot.
