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.

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.

This article introduces a new type of low starch puffed fish feed that can meet the nutritional needs of fish growth, while also improving the quality and taste of fish meat. Compared with traditional fish feed, low starch puffed fish feed has higher nutritional value and lower cost, making it a new choice for healthy aquaculture.

In 2022, a Korean customer purchased a 1.5-2 ton abalone feed production line. Now the production line has been put into use. The returned 2-ton abalone feed production line has also arrived at the customer's factory, and the new production line is being installed and debugged. By the end of this year, it is expected to place an order for a 3-ton shrimp feed production line.

Screw extrusion puffing, as an important hot processing method, is widely used in the maturation and aseptic treatment of feed. With the popularization of puffing technology in the feed industry, more and more manufacturers are entering the field of puffing equipment manufacturing. Due to the lack of relevant standards in puffing machines, many enterprises blindly imitate and produce without standards, resulting in low product quality. On the one hand, there are numerous puffing machine products in the market with varying quality, and on the other hand, users lack relevant professional knowledge, making it difficult to distinguish and do not know how to choose the suitable puffing equipment for themselves. As a professional manufacturer of puffing machines, we are willing to provide advice to our customers on puffing and related issues that everyone is concerned about.
