With the in-depth study of the feed industry, more and more scientific research workers and manufacturers have improved feed processing technology as an important way to improve product quality while improving the quality of raw materials and optimization formula. The particle hardness of the particulate feed is an important indicator of the quality of the particle feed. During the feeding process of some pig farms, the particle hardness of the particulate feed has a certain impact on the production of livestock and poultry. Therefore, how to regulate the particle hardness of the particulate feed is a problem that some manufacturers and researchers are actively exploring. Throughout the whole process of particle feed processing, except for feed formulations, the processing process of particle hardness affecting the particulate feed is: the pulverization process of raw materials; the puffed and expansion process of the raw material; the mixing of the raw material, the water, the injector process; steam Warming process; the choice of mold during granulation; follow-up, post-spray process; dry cooling process.

P5H China Feed Industry Information Network – Bit Feed Serving livestock Factors of determining to particle hardness in the pulverization process are the pulverization of the raw materials. In general, the finer the raw material is pulverized, the more easily gelatinizing the starch during the conditioning process, the stronger the bonding effect in the particulate material, the less the particles are not easy to break, the higher the hardness, in practice, according to different The production performance of the animal and the size of the ring-molded aperture, the crushing granularity requires appropriate adjustment, the chicken duck material requires a thick particle size, the average particle size of the pulverization is 800 ~ 900 mu; m, the milk pigment requires fine, pulverized average particles The average particle diameter of 400 to 500 mu; m, fattening pigs pulverized at 600 ~ 700 mu; m, fish and special aquatic product pulverized particle diameter requirements, generally at 250 mu; m below. In avian feed, the particulate strength of the particulate feed is generally required, and the powder is low, and the waste of feed is reduced. To increase the particle hardness of the poultry particulate feed, the purpose of improving the hardness of the particle hardness can be achieved by regulating the roughness, neutralization of the raw material. The crude particles refer to the particle size at 900 mu; m or more requirements no more than 15%, and the medium particles refer to the particle size at 700 mu; m is about 35%, the fine particles refers to the particle diameter at 500 mu; M, M, below 50%, require more than 50% . Among them, the particle size is less than 250 mu; M powder is not less than 25%. This part of the starch in the fine powder can be fully gelatinated during conditioning, play an important bonding effect during the granulation process, bonding the particles of thick, medium and fine particles to a large particle, improve the particles. Hardness and reduced product powder. In the production of pigs, the hardness of the particles should generally be moderate, too hard to reduce the properness and production performance of the product, and the brittle product powder is improved, reduce production performance, and increase waste. In the production of pig materials, the pulverization particle size is generally required between 700 ~ 500 mu; m.Over 70%, 250 mu; m below 20%. Such particle size distribution facilitates particulate granulation and improves the quality of the particles, and ensures proper hardness and lower powder rate of the product. In the production of fish, in one aspect, the physiological characteristics of fish animals require the raw material pulverization particle diameter at 250 MU; M m below 85%; on the other hand, the particle size is advantageous for the formation of the particles and stability in water. However, the particle hardness of the fish is relatively large, which is due to the stability of the fish in the water, and the particles should be dense. The current produced fish is hard pellets, and should develop in the direction of soft granules.

Protein degeneration in the raw material, blend of starch. The impact of starch after gelation is significant. At present, puffed raw materials is mainly used in high-grade lactagns and special aquatic products. For special aquatic products, the raw material is increased by the expansion, and the hardness of the particles after the formation is also increased, which is advantageous to improve the stability of the particles in water. For milk pigs, the particles are required to be crispy, and they cannot be too hard, which is beneficial to the feeding of the pig. However, the plowed pig pork particles are large because the gelatin of the starch is large, so the hardness of the granulation particles is also large. The hardness of the particles should be reduced by other means. P5H China Feed Industry Information Network – Based on Feed, Serving Animal Husbandry

The uniformity of various particle size components can help keep the particle hardness basically consistent, improve product quality. In the mixer, water is still a problem that is actively exploring. In hard particle feed production, 1% to 2% of moisture is added to the mixer, which is advantageous to improve the stability and hardness of the particles of the particulate feed. However, due to the increase in moisture, the drying and cooling of the particles brings a negative effect. Also disadvantageous storage. In the production of wet particle feed, the powder can be added as high as 20% to 30%, and a moisture of about 10% is added to the mixing process, which is more easier than the addition during the conditioning process. The granules, hardness, wet soft, soft, and good premium, can improve the production performance of livestock and poultry. This wet particulate feed can be used in large aquaculture enterprises. Wet particles generally cannot be stored, generally requiring production, feeding. Adding oil during the mixing process is a grease-added process that is commonly employed in the feed production workshop. addAdd 1% to 2% of the oil fat to low particles, the hardness of the particles is not significant, and the hardness of the particles can significantly reduce the hardness of the particles when adding 3% to 4% of the fat.

is a key process in the process of granule feed processing, and the conditioning effect directly affects the internal structure and appearance quality of the particles. Steam mass and conditioning time is two important factors affecting the conditioning effect. High-quality dry saturation steam can provide more heat to increase the temperature of the material, make the starch amine, the higher the quasithry, the higher the starch demetrifier, the formation of the particle structure is more dense, the better the stability, the hardness The bigger it. For general livestock, by adjusting the amount of steam to be added, the conditioner temperature is maintained at 70 to 80 ¡ã C, and the conditioning time is controlled by changing the length of the plaster, the blade angle and the rotation speed control the conditioning time in 30 seconds. For fish, there are generally double or multi-layer jacket teshes to improve the temperature and prolong the tether. More conducive to improving the stability of the fish particles in water, the hardness of the particles is also increased accordingly.

Selecting a suitable compression ratio ring mold, which can produce particles suitable for hardness. The length of the particles has a significant effect on the pressure of the particles, the same diameter particles, the longer the particles length, the greater the hardness of the particles in the case where the particles have no defects. Adjust the position of the cutter, maintain a suitable particle length, so that the hardness of the particles can be substantially consistent. The particle diameter cross-sectional shape also has a certain effect on the hardness of the particles, and the 8-shaped cross section is stronger than the circular cross-section, the greater the hardness value of the measured. In addition, the material of the ring mold has a certain effect on the appearance quality and hardness of the particles. The pellets produced by ordinary steel ring and stainless steel ring mold have a more significant difference. P5H China Feed Industry Information Network – Best Feed, Serving Animal Husbandry

The post-spray process is relatively small in the production process of livestock and poultry feed production, while the fish material and special aquatic product production process are relatively widely used. Five maturing can make the particlesThe internal starch is fully pouring, making the internal structure of the particles more dense, preventing water from infiltration, facilitating the stability of the water feed particles in water while also improving the hardness of the particles. The rear spray process is in hot particle feed spraying techniques, the sprayed oil or other sprayed can penetrate inside the particles, so that the internal structure is loose, reducing the hardness of the particles, but can prevent the immersion of water, improve the stability of the particles in water.

In order to extend the storage time of the feed product, it is ensured that the quality of the product is required for a certain period of time, and the necessary drying and cooling treatment is required for the feed particles. In the test of the particle hardness, the hardness of the particles was discovered by the hardness of the particles, and the hardness of particles was not obvious, and the hardness of the particles was not obvious, and the hardness was more affected by the cooling time of the hardness of the particles. The large particles are reduced as the cooling time is long. This may be because the brittleness of the particles increases, affecting the hardness of the particles. At the same time, the weight of the particles (the wind door is all open) is quickly cooled (3 minutes in cooling time) and small air volume (the damper is closed to one-third) is slowly cooled (20 minutes by cooling time), and the former is discovered. The hardness is reduced, and the surface crack of the particles is increased. Further, it is worth mentioning that the large hard particles are broken, so that large particles become small grains, the hardness of the particles can be significantly reduced. During the processing of particle feed, the factors affecting the hardness of the particles are far from these. With more and more enthusiasm for the in-depth study of the scientific and technological workers of feed processing technology, more and more methods of regulating particle hardness are people Mastered, I believe that in the near future, we can processed a variety of animal preferences of granule feed.
