Feed pellet machine (also known as: pellet feed machine, pellet feed molding machine), belongs to feed pelletizing equipment. Is corn, soybean meal, straw, grass, rice husk and other pulverized material directly suppress grain feed processing machinery.
How to reduce the feed cost and meet the nutritional needs of livestock and poultry has become the primary problem for the majority of farmers and feed industry. Straw biochemical technology of protein feed is the crop straw through crushing, fermentation, granulation technology measures, such as lignin was softened, crude protein, crude fiber and crude fat degradation into livestock are easy to digest absorb substances, protein fermentation at the same time also produces large quantities of bacteria, fermentation become soft, sweet, granulation increased livestock palatability, Crude protein and amino acid levels will be increased by 40.6% and 95.8% on average, arginine, cystine and histidine levels have increased significantly, increase in sugar, fat, and produce B, D, E and other vitamins and growth factors, and then mixed with other raw material mixture full price feed by the particle feed machine pressed into nutritious feed particles, leading to a huge increase in livestock feed intake, Growth accelerated. Reducing grain input (each ton of straw feed is equivalent to 270 kg of nutritional value of grain feed) saves feed costs and increases farmers' income.
Classification of feed pellet machine
Feed pellet machine, is divided into ring mold feed pellet machine, flat mold feed pellet machine, feed pellet machine roller; According to the use can be divided into: small household pellet feed machine, poultry feed pellet machine, small poultry pellet feed machine, fish feed pellet machine, rabbit feed pellet machine, pig feed pellet machine, straw feed pellet machine; According to the production can be divided into: straw feed pellet machine, wheat bran feed pellet machine, soybean meal feed pellet machine, corn straw feed pellet machine, wood pellet machine and so on. A variety of different feed pellet machine, in appearance and production mode of different to the classification.
The scope of use of feed pellet machine
Feed pellet machine, widely used in large, medium and small aquaculture, grain feed processing plants, livestock farms, poultry farms, individual farmers and small and medium-sized farms, farmers or large, medium and small feed processing plants.
Feed pellet machine main performance characteristics
1. Simple structure, wide adaptability, small footprint, low noise.
2. Powder feed and grass meal can be pelleted without the addition of a little liquid, so the moisture content of pellet feed is basically the moisture content of the material before pelleting, which is more conducive to storage.
3. Chicken, duck, fish, etc., can obtain higher economic benefits than the mixed powder feed.
4. Dry material processing, the production of feed particles with high hardness, smooth surface, internal maturation, can improve the digestion and absorption of nutrition.
5. Grain formation can denaturate trypsin resistance factors in grains and beans, reduce adverse effects on digestion, kill various parasitic eggs and other pathogenic microorganisms, and reduce various insect and digestive system diseases.
Common faults and troubleshooting of feed pellet machine
The fault phenomenon
1. Low yield (even no grain)
The cause of the problem
1. Poor finish of die hole for first use of flat die;

New scheme of feed pellet adjustment technology
One: debugging process
1. First of all, we should understand the technological process of pellet feed production line and the function of each specific equipment in the technological process; 2. Before debugging, check the operation of a specific equipment one by one, and understand the crushing particle size of the crusher that matches the die hole of the granulator used. The particle size of raw materials should be fine, but not too fine, preferably coarse, medium and fine. A, more than 3.35mm particle size ≤1% B, more than 2.0mm particle size ≤5% C, more than 1.0mm particle size about 20%≥ < > D, more than 0.5mm particle size about 30% E, less than 0.25mm particle size not less than 20% F, more than 0.25mm particle size about 24% or so 3, before debugging to wash the warehouse, remove the stones and welding slag and other sundries left during installation; 4, before debugging, check whether the steam pipeline system used has good decompression function and hydrophobic function, in order to ensure the drying and saturated quenching and tempering steam required for granulation, and to ensure that there is always 0.058-0.4mpa steam after the pressure reducing valve; 5, before start the pelletizer should adjust the distance between the roller and ring die, generally for the rotating ring die when the roller turn not turn (i.e., roller and ring die spacing is 0.1 ~ 0.4 MM is best), don't make the ring die and a tuning roller spacing is too small, lead to direct friction, such not only can accelerate the ring die and roller friction losses, and to reduce the production of unit production. 6, start pelleting equipment should not make the feeding amount to reach the maximum instant, should add a little material, while adding a little steam about 5-10 minutes to make the feeding amount to reach the ideal value (that is, normal production motor current value is 85~95% of the rated current value).
Two: the prevention and corrective measures of undesirable phenomena.
1, the particles have axial crack or radial crack phenomenon, and the pulverization rate is high, the output is low, leading to the reason of this phenomenon can not reach the adjustable tempering temperature, the material curing degree is poor, should improve the tempering temperature, increase the amount of steam when tempering; It may also be that the cutter position is far away and blunt, so that the particles are short or torn rather than cut;
2. The particle surface is not very smooth, and the pulverization rate is high. It may be that the compression of the ring mode is relatively small, so the compression hole should be increased. Ring mode compression;
3, the particle surface is smooth, but the hardness is too high, may be the ring modulus compression ratio is large, should reduce the ring modulus compression ratio;
4, when the particle moisture is high, the production output is low, and often appear blocking machine phenomenon, which may be that the pressure reducing valve can not play the decompression effect or the trap can not play the role of hydrophobic, should adjust the pressure reducing valve, so that the steam pressure into the conditioner is 0.1-0.4mpa, and the trap can play the role of hydrophobic. The quenching and tempering temperature can also be increased accordingly, because the increase of temperature is conducive to the improvement of the degree of maturation of the material. Generally, the moisture content of the material increases about 1% when the temperature increases 11℃.
5, particle length is different, should adjust the cutter distance or adjust the material deflection scraping position;
6. If the current deviation of the two motors is large, the belt tension of the two motors should be adjusted to make the tension as consistent as possible.
According to authoritative data, in recent years, due to consumer demand and breeding structure changes, China's feed product structure has changed greatly, the price of small feed pellet machine so that China's aquatic feed output annual growth rate of up to 17%, much higher than the average growth rate of 8% with feed, pig feed, poultry feed proportion was a downward trend. Aquatic feed has become the biggest window in the development of feed industry. In 1991, China's aquatic feed output was only 750,000 tons, accounting for only 2.1% of China's total feed output. By 1999, however, production had surged to 4 million tons, or 5.8 percent of total feed production.
In order to make China's aquatic feed industry can develop along the road of science, from the "six five", the country to China's main breeding object nutritional demand and feed formula organized a national scientific and technological breakthrough, "six five" to "nine five" period, Small pellets machine price respectively carried out "the main nutritional requirements of farmed fish and fish feed formulation study", "main aquatic animal feed standard and testing technology research", "fish nutrition and feed preparation technology research", etc., it is to our country the main object of famous quality breeding of feed additives, premix etc were studied. The feed formula and additive premix formula of grass carp, black carp, megalobrama amblycephala, carp and Nile tilapia were put forward, and the feed standard of eel and Chinese penaeus chinensis (code names are SCL004-92 and SC2012-94, respectively) was promulgated. Work is currently under way on the development of feed standards for some major farmed fish. Research on feed and additives for turtle, river crab, grouper, large yellow croaker and other Marine and freshwater aquaculture objects has been carried out. At the same time, China's aquatic feed in feed raw materials, processing, machinery, additives and research and development conditions, test means, quality monitoring, scientific research team construction, talent training many aspects, have been the corresponding development, with further research and development and development of industrial production capacity.
In recent years, China's small feed pellet machine price aquatic feed industry advanced all the way, the direct reason is due to the domestic aquaculture industry has continued to grow. As is known to all, China is the largest aquaculture country in the world, and the only country in the world where aquaculture output exceeds fishing output. At present, the total production of aquatic products in China accounts for about 35% of the global total, among which the aquaculture output of aquatic products accounts for 2/3 of the global aquaculture output, ranking first in the world for 13 consecutive years. Aquaculture production accounts for such a high proportion, which is unique among the world's major fishing countries. China is the country with the largest aquatic feed market capacity in the world. It is because of the huge aquaculture market that aquatic feed industry in China has brought huge development space. What is striking is that after the 1980s, the aquaculture of famous and excellent aquatic products represented by prawns, eels and turtles developed rapidly, forming bursts of "aquaculture fever". Feed processing industry, one of the material basis of aquaculture development, has been developing rapidly, many famous enterprises have emerged, and some famous brand feed is favored by farmers.
According to the 2010 Food Development Program, China's per capita share of aquatic products will reach 44 kilograms in 2010, or 57.2 million tons, compared with 33.8 kilograms at present. Therefore, in the next six years, there will be a big increase in aquaculture output. And China's existing small feed pellet machine price aquaculture production of 25 million tons of products, only about 20% of feed production. According to the policy of our country, the sea and river fishing production keep zero growth, aquatic products of the total growth will largely by aquaculture production to provide, the forage breeding is expected to increase by more than 35%, the proportion of the market demand of aquatic feed in 2010 will reach 1500 ~ 20 million tons, will be on the basis of the existing production increased 1.5 ~ 2.5 times.
