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.

Fat is a collective term for fats and oils, and is one of the main nutrients in pet food. The chemical elements contained in fats are mainly C, H, O, and some also contain elements such as N, P. 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.

As people's attention to pet health continues to increase, the pet food market is also becoming increasingly prosperous. As an advanced food processing technology, pet feed puffing can provide pets with a healthier and more delicious diet. This article will introduce the principles and advantages of pet feed puffing, as well as how to choose the appropriate puffing feed, to help you provide your pet with the best dietary experience.

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 cavity through the feeding port, and the screw is rotated and extruded to be transported forward. Under the action of thrust, friction, shear force and heat, a high-pressure and high-temperature difference is formed inside and outside the cavity. The moment the material is extruded, Instant expansion due to pressure difference.

Feed refers to feedable substances that can provide nutrients needed by animals, promote animal growth, production and health, and are safe and effective when used appropriately. According to product variety, feed can be divided into pig feed, egg poultry feed, meat poultry feed, ruminant feed, aquatic feed, pet feed and other feed.
