The dry powder
Granulator feeding structure plays a decisive role in the dry-roll forming of the drug. The domestic feed system generally adopts special-shaped unequal-distance screw to feed directly, and can give a certain pre-pressure to the feed screw during the feeding process, so that the hardness and thickness of the pressed material are ensured, so that the pressed medicine sheet meets the required requirements. The key to the dry powder granulation system is to crush and granulate the sheet formed by rolling. After obtaining the pellets with uniform particles and high yield, the company uses the first to break the pellets and then rolls it through the drum. The granulation structure is pressed onto the screen. Can greatly improve the production efficiency of the finished product. The use of dry powder granulation pellet feed has many advantages; 1. It can avoid animals picky eaters. Formulated feed has a variety of raw materials, nutrition, comprehensive, can prevent animals from the powder to choose their favorite, refused to intake of other ingredients phenomenon. Because the pellets of the dry granulator can maintain homogeneity during storage and feeding, it can reduce feed losses by 8% to 10%. 2. Avoid automatic classification of feed ingredients and reduce environmental pollution. In the process of powder storage and transportation, due to the different volume and quality of various powders, it is easy to produce grading. After the granules are made, there is no grading of the feed ingredients, and the granules are not easy to dust. In the feeding process, the granules are less polluted by air and water than the powder. 3. The feed rate is high. During the process of dry granulation, due to the combined action of moisture, temperature and pressure, some physical and chemical reactions occur in the feed to gelatinize the starch and enhance the activity of the enzyme, enabling the fed animal to digest the feed more efficiently and convert it into Increase in weight. Feeding poultry and pigs with pelleted feed can improve the feed conversion ratio (ie, return rate) by 10% to 12% compared to powdered feed. Feeding finishing pigs with pellets has an average daily gain of 4% and a feed-to-meat ratio of 6%. For broilers, the feed-to-meat ratio can be reduced by 3%-10%. 4. Good liquidity and easy management. Many powders, especially those with a small specific weight, feeds with added molasses or high-fat and urea, often adhere to the feed. Due to the good fluidity of the pelleted feeds, there is very little stickiness, and pelletized feeds are the most popular for farms that use automatic feeders to scale up dairy cows or poultry. 5. Storage and transportation are more economical. After granulation, the bulk density of the feed is generally increased by 40% to 100%, which can reduce the storage capacity and save transportation costs. 6. Kill Salmonella in animal feed. Salmonella is preserved in animal tissues when ingested by animals. People who eat this bacteria will get salmonella stomach disease. The method of re-granulation by steam high temperature quenching can kill Salmonella in animal feed.
