The company has a complete range of manufacturing equipment, diverse products, and complete supporting series. Customers can purchase all the equipment they need in one stop. At present, it is the main professional manufacturer, manufacturer and R&D manufacturer of extrusion puffing equipment and its supporting equipment in China.

Twin screw advantage

1. The raw material has a wider adaptability and can be adapted to the processing of high viscosity, low viscosity, high oil content, high moisture or viscous, oily, very wet and other materials that will slip in a single screw (SSE).

2. There are fewer restrictions on the particle size of raw materials, and it 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 a particle size outside the specific range of single-screw processing.

3. The material flow is more uniform in the barrel, which can be more proportional to the actual demand regardless of the addition of steam, water and other auxiliary processing processes.

4. The internal and external quality of the product is better, it can achieve a very good homogeneous state and make the molecular structure of the material evenly distributed, the surface is smooth during the extrusion process, and the product particle has high uniformity and uniformity.

5. The effect of ripening and homogenization is better. Usually, the starch ripening degree can reach more than 95%, so that the processed aquafeed can be kept stable in water and the nutrient components of the product will not be lost, and it is easy to digest and absorb.

6. The output is higher under the same power, and the good mixing performance makes the heat obtained by the material uniform in time, which speeds up the maturation of the material, reduces the fluctuation of material temperature, and improves the output of extruded products.

7. The product diversity and adaptability are wider, and it can process particulate aquatic feed, high-oil formula, high-moisture, high-cohesion products and multi-color, sandwich, and special-shaped products.

8. The process operation is simpler, and the spindle speed can be adjusted according to the needs of the processed products. Due to the self-cleaning feature, the cleaning is very convenient, and there is no need to disassemble and assemble the equipment after each processing.

9. The wearing parts are lighter. Usually a misconception thinks that the wear of the single screw is less. In fact, during the twin-screw extrusion process, due to the characteristics of stable material conveying and material flow, it determines the impact of the material on the screw and barrel. The wear of the sleeve is smaller than that of the single screw. Although there is more than one set of screws, the cost of the accessories is still lower than that of the single screw.

10. The production cost is lower. Due to the good operation stability of the twin-screw model, in the feed processing process, the startup cost is less, the waste of water and gas is less, the labor cost is less, the heat transfer efficiency is high, the yield is high, and the electricity output is high. With high indicators and low cost of accessories, the final production cost is still much lower than that of a single screw.
