aquatic starter

What do you think of the future of open-ended aquatic feed? Would you please introduce the open feed of aquatic products? -- this post was finally edited by s0311319 at 16:56 on 2009-11-30. At present, there is no really qualified opening material. Yang Baoqin recommended from "Animal Husbandry and Veterinary Science and Technology Information} 2001.12 Fish and Shrimp Open Feed, also known as particulate Feed." . it is processed according to the living habits of the seedlings. Physiological functions and nutritional requirements of different growth periods At the same time, it also needs to meet the requirements of particulate feed, such as strong suspension, high stability in water, low solubility, easy digestion and absorption and different particle size. The processing techniques of particulate feed commonly used in foreign countries are as follows: 1. In the feed processing technology, the large pellet feed to be extruded by the granulator is treated by the crusher, and then screened by the vibration of different mesh. Get the required different specifications of particulate feed. 2. Micro-particle processing. The formula raw materials needed for the seedlings were fully mixed and mixed with the mixture, and then machined into micro particles of different sizes by ultra-micro grinders, and the micro particles with different mesh numbers were obtained by vibration screening. 3. Microcapsule processing technology. This technology is the most advanced in Britain. After years of evolution, physical mechanical forming and chemical solidification forming have been formed. the former adopts spray drying and the latter adopts single condensation and complex condensation. This technology has the advantages of simple forming and low cost. There are many professional opening materials on the market, which can be used for reference.
