Twin Screw Extruder and Aquatic Feed Processing
Twin Screw Extruder and Aquatic Feed Processing
Expanded aquatic feed is a kind of high-quality environmental protection feed with low pollution, low waste and high efficiency, which has incomparable advantages compared with other feed processing technologies. Extrusion processing technology has unique advantages: wide range of raw materials, high gelatinization degree of starch, water stability is much higher than that of ordinary pellet feed, and because the structure of extruded particles is loose (density can be adjusted), it is conducive to the use of post-spraying technology, avoid the loss of heat-sensitive raw materials, and improve nutritional value. Reduce production costs. The application of extrusion technology in aquatic feed is developing rapidly, and the application of aquatic extruded feed in aquaculture is becoming more and more extensive and mature. Twin-screw extruder is the only way to produce feed with uniform ripening, high appearance ripening and floating in water.
According to the number of screw, it can be divided into single screw extruder and twin screw extruder. The single screw extruder is driven by belt and the twin screw extruder is driven by gear box. Both of them have great differences in manufacturing and transmission efficiency, so they will directly affect the performance of the extruder.
Twin-screw extruder fish feed has obvious advantages in quality control and processing flexibility, and can process viscous, multi-oil and high moisture raw materials, so it is widely used in feed processing, especially in aquatic feed processing.
