The twin-screw feed extruder is mainly composed of a barrel and a rotating extrusion twin screw inside 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.

Before production, a comprehensive inspection must be conducted.

Fish feed is food for ornamental fish. Whether the fish feed is of high quality should be checked from multiple aspects such as color, smell, water resistance, and specifications. In addition, the inspection of high-quality fish feed should also take into account its nutritional formula additives, etc. If you keep fish feed for a long time, you will slowly form your own judgment criteria for the quality of fish feed.

Animal liver is well known as one of the ingredients added to commercial pet food. The collection, storage and processing of liver are also very difficult. The animal liver added to pet food can be unprocessed, that is, cooled or frozen, can be a dry powder after hydrolysis, or a component of the seasoning. Beef liver, pork liver and chicken liver are all common pet food ingredients; professional pet food manufacturers will indicate the source of the liver on the label of the sheep liver, chicken liver, duck liver or goose liver used; livers such as fish liver and other poisonous species are generally not used in commercial pet food processing. For pet food, liver has become an important component of pet food due to its rich nutrients and pet appeal.
