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.

After about two months of design and manufacturing process, a fully automatic fish feed production line with a capacity of 2t/h is ready to be loaded and shipped. The entire production line occupies 5 containers. After two days of hard work by the staff, it was successfully packed and shipped.

Single screw extruder has no gearbox, one shaft, motor direct start; twin screw dog food equipment, has gearboxl, two shafts, frequency conversion control. The twin-screw dog food equipment is more stable, and the feed/food made is smooth in appearance and has a good degree of ripening.

According to different varieties and growth stages, producing puffed floating fish feed that is suitable for their caliber and nutritional needs can well meet the feed needs of conventional aquaculture and special aquaculture, which not only facilitates aquaculture producers but also promotes production development.

In the aquatic feed industry, extruders are widely used. The reason is that the materials produced by extruders are diverse and their maturity is higher than that of pelletizers, which causes much less environmental pollution. Many manufacturers generally Only floating materials are produced.

Extruded aquatic feed can be suspended on the water surface for a long time. There is no need to set up a special feeding platform when feeding, just feeding at a fixed point. Fish need to float on the water surface when feeding, so they can directly observe the feeding situation of the fish, adjust the feeding amount in time, and understand the growth and health status of the fish in a timely manner. Therefore, the use of aquatic extruded feed is helpful for scientific feeding management, which not only saves a lot of time, but also improves labor productivity.

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.
