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 flow is more uniform in the barrel, which can achieve a more accurate ratio and achieve the actual demand effect regardless of the addition of steam, water and other auxiliary processes.

(4) The internal and external quality of the product is better, which can achieve a very good homogeneous state and make the molecular structure of the material evenly arranged, the surface is smooth during the extrusion molding process, and the product particles have high uniformity and good uniformity.

(5) The effect of ripening and homogenization is better. Usually, the degree of starch ripening can reach more than 95%, so that the processed aquatic feed can remain stable in water and the nutritional content 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 can homogenize the heat obtained by the material in time, accelerate the ripening degree of the material, reduce the fluctuation of the material temperature, and increase the output of extruded products.

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

(8) The process operation is more convenient, 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 the equipment after each processing.

(9) The wearing parts of wearing parts are lighter. It is usually a misconception that the single screw has less wear. In fact, due to the stable material transportation and material flow characteristics in the twin-screw extrusion process, the material impact on the screw and barrel is determined. The wear of the inner sleeve is smaller than that of the single screw. Although there is one more set than the number of screws, the cost of accessories is still lower than that of the single screw.

(10) The production cost is lower. Due to the good operational stability of the twin-screw machine, in the process of feed processing, there is less start-up cost, less waste of water and air, less man-hours, high heat transfer efficiency, high yield, and kWh The output index is high, and the cost of accessories is also low, and its final production cost is still much lower than that of single screw.
