First, computer automatic control technology Foreign computer automatic control technology has already been applied to the processing of fish feed. In some large and medium-scale fishery feed processing plants, dozens of feed formulas are accurately controlled by computer automation. The automatic weighing and packaging of pellet feeds is also controlled by computers, with high accuracy. The entire feed processing process has evolved from a single computer control system to an advanced automatic control system. In the central control room, a color image, computer program control and machine operation communication network can be displayed. In the unmanned operation, all production can be completed. program. 2. Spraying Technology In order to formulate and process high-fat, high-quality pelleted feed for fish, liquid spray technology is used to spray fat and vitamins onto the feed. The commonly used method is: In a mixer of a mixer or a granulator, oil or the like is added or sprayed, and the raw materials are uniformly stirred and mixed. 2. An oil injection system is installed in the molding cavity of the granulator to spray grease on the surface of the pellets that have just been extruded, thereby improving the quality of the pelleted feed and improving the palatability. 3. When processing shrimp feed, a set of liquid spray equipment is used to spray oil and spray vitamins. Thus greatly improving the quality of shrimp feed. Third, the use of steam on the feed conditioning steam on the material conditioning the earliest applied to the granulator and extruder conditioning machine, the material can be aging softening, and can increase the production of granulation. Now, with the improvement of shrimp feed processing requirements, how to solve the problem of increasing the water stability of pelleted feed without adding a binder has become an urgent problem to be solved. Some foreign feed mills use a three-layer steam conditioner on the pelletizer to stabilize pellet feed water for more than 10 hours. The pellets have a smooth surface and good texture. Fourth, fish and shrimp seed opening feed processing technology Open feed is also called microparticle feed, it according to the seed's living habits, physiological function and nutritional needs of different growth period for processing, but also need to meet the microparticle feed suspension, water stability Sex, low solubility, easy digestion and absorption and different particle size requirements.
