Extruder machine

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.

The twin-screw feed extruder is mainly composed of a barrel and a rotating extrusion twin screw in the barrel. When the equipment is running, the material enters the material chamber through the feeding port, and the screw rotates and extrudes forward to transport it. Under the action of thrust, friction, shear force and heat, a high pressure and high temperature difference is formed inside and outside the chamber. The moment the material is extruded, it expands instantly due to the pressure difference.

The fats in pet food provide fat for pets. For pets, fat is an important component of their body tissue. Fats are found in the skin, bones, muscles, nerves, blood, and internal organs of pets. Most lipids are important components of cell membranes, and they are also raw materials for cell proliferation, renewal, and repair. At the same time, fat also participates in the synthesis of certain metabolic regulatory substances in cells, such as sex hormones and bile acids. In pet dogs, fat accounts for 10-20% of their body weight. When the proportion of fat reaches a certain level, it will increase the palatability of cat food. In pet food, to meet its fat content requirements, the amount of fat added is usually about 10% of the formula.
