How to control the processing quality of feed

1. Best crushed particle size control. The key to this technology is to crush various Feed ingredients to the most suitable particle size for animal use, so that the compound feed product can obtain the best feeding efficiency and economic benefits. In order to achieve this goal, it is necessary to thoroughly study and master the optimal particle size of different feed ingredients for different animals. For aquafeeds, microcrushing and ultrafine crushing techniques must be used. 2. The accuracy of ingredients is controlled. The use of error-free computer dosing control technology enables precise control of the amount of ingredients for each ingredient in each ingredient. Pre-mixed trace additives can be pre-mixed and used with a high-precision micro-ingredient system. 3. Mixing uniformity control. This includes mixing uniformity control technology for compound feeds, concentrated feeds, additive premix feeds, and liquid feeds. Choosing the right mixer and the appropriate mixing time and method are the key to ensure the quality of mixing. 4. Granulation quality control. In this regard, the first step is to control the quality of the feed, that is, to control the tempering temperature, time, moisture addition, and the degree of gelatinization of starch, so that the state after conditioning is most suitable for granulation; the second is to control the hard pellet feed pulverization. Rate, cooling temperature and moisture, particle uniformity, consistency, water resistance. To achieve these requirements, it is necessary to provide a reasonable steam supply and control system and conditioning, granulation, cooling, screening equipment, and scientifically adjust the control parameters according to the different requirements of the product. 5. Extruded pellet feed or swollen feed quality control. The first is to control the quality of the feed, that is, to control the temperature, time, moisture addition and starch gelatinization, so that the state of quenched and tempered is most suitable for extrusion or expansion; second is to control the expansion pellet feed. Degree of maturation, density, chalking rate, cooling temperature and moisture, particle uniformity, consistency, and water resistance. To achieve these requirements, we must be equipped with a reasonable steam supply and control system and conditioning, extrusion, expansion, drying, cooling, screening equipment, and scientifically adjust the control parameters according to the different requirements of the product in order to obtain customer satisfaction products . 6. Liquid added quality control. With the continuous development of feed processing technology, many additives will be added in the form of liquid powdered, granular and extruded feed, and maximize the activity of these additives, reducing feed costs. One is to achieve precise control of the amount of liquid added, the other is to achieve a uniform distribution or coating of the liquid in the feed, and the third is to ensure the stability and validity of the liquid additive after spraying. This requires the use of high-performance atmospheric pressure liquid spray equipment, vacuum spray equipment and control technology. 7. Control of feed cross-contamination. The sites where feeds cross-contamination mainly include: spilled and mixed in the storage process; residues in transportation equipment lead to cross-contamination between different products; cross-contamination caused by residue in silos and buffer hoppers; and residues in processing equipment. Cross-contamination; cross-contamination caused by harmful microorganisms and insects. Therefore, it is necessary to adopt non-residual transport equipment, silos, processing equipment, and proper cleaning, sorting, and flushing technologies and independent production lines to meet the ever-increasing requirements for feed safety and hygiene. 8. Cleaner feed quality control. This control technology includes cross-contamination control techniques, and also includes the necessary heat treatment and sterilization of feeds. Heat treatment includes high-temperature cooking, extrusion, high-pressure treatment, ultraviolet irradiation and other process technologies, these technologies can usually be combined with ordinary processing technology, can also be implemented alone.
