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 rotates and squeezes forward to be transported. 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.

Advantages of twin-screw extrusion extruder(1) The adaptability of raw materials is wider, and it can adapt to the processing of raw materials with high viscosity, low viscosity, high oil content, high moisture or viscosity, oily, very wet and other slippery materials in single screw (SSE).(2) There are fewer restrictions on the particle size of raw materials, which can be adapted to the processing of raw materials with a wide particle size or from fine powder to coarse powder particles and raw materials with particle sizes outside the specific range of single-screw processing.(3) The material

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.

Decryption of Large Twin-Screw Extruder1.Principle and working processThe large twin-screw extruder is an important piece of equipment in the food processing industry and plays an indispensable role in the food production process. This article will reveal the principles, applications and advantages of large-scale twin-screw extruders, and let us explore this eye-catching industrial device together.2. ExtruderThe large twin-screw extruder uses advanced extrusion technology to process ingredients under high temperature and high pressure. It is mainly composed of two rotating screws.

The kinds of fish feed have long long past through a technique from uncooked to cooked, from shallow processing to deep processing, from the original fish and shrimp overwhelmed right now to feeding, to the later matured pellet feeding, to the modern nutrient ratio clinical feeding. the extruded fish feed equipment and tool production line specializes in the production of severa sorts and specifications of extruded aquatic fish feed for small and medium aquaculture farms and person fisheries.

First of all, we take the production of aquatic feed as an example, according to the material and purpose of the expansion from the structure of the single screw extruder and twin screw extruder,In general:--- Single screw extruder: suitable for processing all kinds of raw materials and common livestock and poultry compound feed.--- Twin-screw expander: The final product requires good molding and beautiful appearance, uniform maturation and adjustable density of compound feeds (aquatic food and pet food) and high value-added raw materials (alpha starches and histones), etc.

The moisture content of pellet feed is a very important quality index, which directly affects the quality of pellet feed and the economic benefits of feed enterprises. Effective control of it is one of the key technologies to ensure the quality and safety of feed products. If the moisture content exceeds the specified standard, the pellet feed is prone to mildew and deterioration, which is not conducive to preservation, and will also reduce the content of nutrients. The moisture content also causes unstable product quality and affects the brand reputation of the product.

Advantages of Twin Screw Square Barrel ExtruderTwin-screw square barrel extruders are mainly used to produce various snacks and foods. Including puffed snacks, fried snacks, artificial rice, macaroni, etc.

Twin Screw Fish Feed ExtruderOn April 5, the twin-screw fish feed extruder purchased by the Indian agent was successfully shipped. So, why do more and more customers choose twin-screw extruders? Let's analyze it.Advantages of twin-screw extruder：The function of the extruder screw is to push the material forward in the screw groove, convert the material from solid to molten, and form shear on it, and supply material to the die of the machine head in a fixed and quantitative manner according to a certain compression ratio.

Daily Troubleshooting of Twin-screw ExtruderThe 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.
