In the production process of puffed food, uneven product discharge and spraying often occur, which affects the puffing degree and effect. Today, I will share with you some troubleshooting methods.

Wheat bran, also known as wheat husk, is a byproduct of wheat flour processing. It is wheat yellow, in the form of flakes or powder. At the end of the wheat husk, there are some embryonic buds (which are the part where the wheat sprouts), accounting for about 5-10% of the total amount of wheat husk. Some of them are about one-third to half of the flour, and the wheat husk is divided into six layers. The outer five layers contain more crude fiber, are less nutritious, and difficult to digest. Wheat husks contain a large amount of vitamin B. Rich in cellulose and vitamins, it is mainly used for food, medicine, feed ingredients, brewing, and other purposes.

The twin-screw feed puffing machine mainly consists of a barrel and rotating extrusion twin-screw components inside the barrel. When the equipment is in operation, the material enters the material chamber through the feeding port, and the screw rotates and squeezes it forward. Under the action of thrust, friction, shear force, and heat, a high-pressure and high-temperature difference is formed inside and outside the chamber. At the moment when the material is extruded, it expands due to the pressure difference.

The twin-screw extruder is a kind of multi-screw extruder. It is developed on the basis of the single-screw extruder. In the barrel of the twin-screw extruder, two screws are placed side by side. Therefore, it is called twin-screw extruder. According to the relative position of the screw, it can be divided into meshing type and non-meshing type. The meshing type can be divided into partial meshing type and full meshing type. According to the rotation direction of the screw, it can be divided into two types: co-rotating and counter-rotating. Counter-rotating It can be divided into two types: inward and outward.

The application of twin-screw extruder in the production of extruded feed The key to the production process of extruded feed lies in the extrusion process, and the twin-screw extruder is an important equipment to complete this process.

Large twin-screw extruder is an important equipment in the food processing industry, which plays an indispensable role in the food production process. This article will reveal the principles, applications and advantages of the large twin-screw expander, and let us explore this compelling industrial device.
