This paper discusses some discussion for the powder of particle feed, and proposes some measures to reduce powder. Powder of the particulate feed refers to the phenomenon of phenomenon in which the particles depressed due to various reasons such as flow, transportation, cooling. For a long time, people have tried to reduce the powder because the resulting powder affects the formation rate of the finished product, and increases the energy loss of the granulation. There are many factors that cause particulate feed powder, such as physical and chemical properties of raw materials, pulverization particle size, granulation process and equipment and cooling process. Therefore, in order to reduce the powder, it must be studied from these aspects. W2Z China Feed Industry Information Network – Based on Feed, Serving Animal Husbandry
W2Z China Feed Industry Information Network – Bit Feed, Service Livestock Different raw materials composed of feeds have a large difference in granulation performance. Corn and soybean meal content have high granulation properties, and the amount of powder is small, and the formation rate is mostly 95%. W2Z China Feed Industry Information Network – Based on Feed, Service Animal Husbandry
The general material is just the opposite, the finished product is only about 90%, and often block the ring mode, resulting in discontinuation. Therefore, under the premise of not improving the cost, it should be as small as possible in the formulation of raw material.

1. A raw material having a higher starch content, during higher temperature and moisture, it can promote starch to grain, when granulation, improve granulation, and the particulate cooling is good, and the powder is low. .

2. Natural protein has a large capacity, heat-sensitive degeneration, which increases its plasticity and bonding, less fine powder produced during crushing, which is conducive to the improvement of granulation production.

3. Appropriate addition of grease will cause the particles to tend to be softized, reduce the resistance of the ring mold, reduce the degree of coefficient wear, increase granulation production, but the amount is not more than 3% W2Z China Feed Industry Information Network – Bit Feed , Service livestock
. The addition of glycans can not only improve the nutritional value, but also use the binder to improve the wear resistance and hardness of the feed. W2Z China Feed Industry Information Network – Based on Feed, Service Animal Husbandry
4. The material of the granulation performance can consider adding some of the glyphs, such as starch, lignin, gelatin, etc., can increase the granulation bonding, but will increase cost. When the granulation conditions are timed (the mass mixing temperature 75 ~ C, granulator rotational speed 250R / min, granulator current 150a, steamPressure 0.22 MPa), different formulations have the following relationship with the amount of feedback flow (sensory identification with ldquo; +, ++, +++, ++++).

W2Z China Feed Industry Information Network – Based on Feed, Service Animal Husbandry [ 123] The purpose of pulverization is to make a better proceed in the subsequent work segment, and also meet the requirements of livestock and poultry on feed particle size. Domestic and foreign influence on feed particle size and particulate powder rate has been a large number of research and trials. As shown in FIG. 1, when the same composition is granulated, the finer the particle size, the better the powder, the lower the powder. Many W2Z China Feed Industry Information Network – Based on Feed, Service Animal Husbandry
When the pulverization particle size is 0.4 to 0.6mm, the granulation effect, power consumption and powder rate are compared. Reasonable. W2Z China Feed Industry Information Network – Based on Feed, Service Animal Husbandry Information Network – Based on Feed, Serving Animal Husbandry
1. Temperature and steam addload W2Z China Feed Industry Information Network – Based on Feed, Serving Animal Husbandry
Starch Polated requires three major elements: moisture, temperature and time. When the moisture content in the material is relatively stable, the control of the steam addition amount adjustment temperature is a key factor. W2Z China Feed Industry Information Network – Based on Feed, Service Animal Husbandry
As the amount of steam is increased, the powder of particles decreases, which is the starch in materials. The results of adhesion were improved due to increased temperature rises and water increases. However, the amount of steam adds a series of problems such as particle deformation, too much moisture, high nutrients and destruction, and other problems. Therefore, it should be appropriately controlled, usually 5% to 6% of production, and the same conditioning time should also be controlled at 15 to 30s.

(1) The distance between the stamper and the pressure rolls should be controlled at 0.2 ~ 0.3mm. If the distance is too large, the extrusion pressure is too small, it is not easy to compact, the degree of maturation is reduced, and the powder is increased and the yield is affected. Generally, the new pressure magic distance should be small to increase the extrusion, forced particles, but the distance will accelerate the wear of the stamper.

(2) The selection of the pressure-mold hole hole is low, and the output is low. Generally, a standard molding of 4.5 mm is often produced. If a chicken material or a lartrum material is produced, it can be suppressed and then crushed, and the particle fine powder is small, and the light surface of the particles is also more.

(3) The adjustment of the knife is interrupted, not cut, not cut. The two ends of the particles are rough, and the particles are curved, resulting in an increase in the content of the finished product, so the cutter should be replaced. In order to avoid the cutter and the compactment phase, the cutter position should be adjusted so that the particle length is 1.5 to 2 times the diameter.

3. Scientific cooling
W2Z China feed industry information network – based on feed, service animal husbandry
The temperature of the particulate machine is approximately 65 ~ 85%, and the moisture is about 10%, so the It is necessary to obtain proper cooling after leaving the granules. However, if the cooling time is too long, it will affect the yield; the cooling time is too short, and the cooling requirements are often less cool, so that the feed moisture is high; and the cooling is too fast, which causes the particle surface shrinkage to spread out, blocking water outward diffuse The passage allows the moisture of the central part to volatilize, causing the undesirable condition of the coordinant, producing cracks on the surface of the particles, which reduces the hardness and wear resistance of the particles, and increases the powder in the product.

The quality of the particulate product is critical to selecting the appropriate cooling time. According to the production practice in the factory, for particles having a diameter of 3.0 mm, the cooling time should be 8 min, the cooling air volume is 1600 m / ht; for particles having a diameter of 4.5 mm, the cooling time is 9 min, and the air volume is 1700 m / h. T is more appropriate.

In short, the powder of particulate feed is inevitable in particle production, and its influencing factors are varied, but as long as The processing process is reasonable, the operation science and quality management can be greatly reduced, and the energy consumption can be greatly reduced, and the product quality can be reduced.
