How to reduce the cost of feed and meet the nutritional needs of all kinds of livestock and poultry has become the most urgent problem for 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, Then mixed with other raw materials into the full - price feed by the pellet feed machine to suppress into nutrient-rich feed particles, so that the intake of livestock increased, growth accelerated. Reducing food input (the nutritional value of each ton of straw feed equals 270 kg of food feed) saves feed costs and increases farmers' incomes.

I. debugging process aj7 China feed industry information network - based on feed, serving livestock husbandry
 
 
 
 
1. First, understand the process flow of the pellet feed production line and the function of each specific equipment in the process flow;
 
 
2, debugging before should examine the workings of a specific device, and understand with hole that match the granulating tools used crusher in the crushing granularity, granularity of raw materials carefully, but unfavorable to go, best coarse, medium and fine, suggested that the ideal particle size distribution is as follows: A 3.35 mm above the granularity of 1% or less, B, C 2.0 mm above the granularity of 5% or less, 1.0 mm above the granularity of around 20% or greater < > D, 0.5 mm above the granularity of around 30% E, 0.25 mm below the particle size is not less than 20%, more than 0.25 mm F the granularity of about 24%
 
 
3. Wash the warehouse before debugging and remove the stones and welding slag left behind during installation;
 
 
4, debugging before steam pipeline system used to check whether has a good function of reduced pressure and hydrophobic function, to ensure that the required when the granulating dry saturated steam conditioning, and can guarantee the pressure reducing valve has 0.058 0.4 MPA steam;
 
 
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, when to start the granulating equipment should not make the feeding rate of instantaneous maximum, should add a little material, and add a little steam for about 5-10 minutes to make feed feed rate to achieve ideal value (that is, when the normal production of motor current value for 85 to 95% of the rated current value).

1, particle axial or radial crack phenomenon of crack, and pulverization rate is higher, the yield is low, the cause of this phenomenon the adjustable temperature reach, material aging degree is poorer, should improve the tempering temperature, increase the quality of steam; It may also be that the cutting tool is far away and blunt, so that the particles are touched short or torn rather than cut off.
 
 
2. The particle surface is not very smooth, and the powder rate is high.
 
 
3. The surface of the particles is relatively smooth, but the hardness is too high. It may be that the annulus mold compression ratio is relatively large, so the annulus mold compression ratio should be reduced.
 
 
4, grain moisture content on the high side when production is low, and often appear machine phenomenon, may be a relief valve can't decompression effect or cannot have hydrophobic effect of the drain valve, pressure reducing valve should be adjusted and made into conditioning unit steam pressure of 0.1-0.4 MPa, and the trap can have hydrophobic effect. Can also be a corresponding increase in tempering temperature because the temperature increase was beneficial to the improvement of the material aging degree, average temperature rise every 11 ℃ material moisture increase about 1%;
 
 
5. The length of granule material varies, and the cutting knife distance should be adjusted or the material deflection scraping position should be adjusted;
 
 
6. The position with large current deviation between the two motors shall adjust the belt tension of the two motors to make the tension as consistent as possible. Aj7 China feed industry information network - based on feed, services livestock husbandry
 
 
 
 
According to authoritative sources, in recent years, due to consumer demand and farming structure change, feed product structure in our country, great changes have taken place has small pellets machine prices make the production of aquatic feed in China an average annual growth rate as high as 17%, far higher than that of compound feed 8% of the average growth rate, swine, poultry, material proportion is on the decline. Aquaculture feed already became the biggest bright spot in feed industry development. In 1991, China produced only 750,000 tons of aquaculture feed, accounting for only 2.1 percent of China's total feed production. By 1999, however, its production had surged to 4m tonnes, or 5.8 per cent of total forage. Aj7 China feed industry information network - based on feed, services livestock husbandry
 
 
 
 
In order to make the aquatic feed industry in our country can along the road to scientific development, starting from the "purpose", the state of our country the main breeding objects of nutritional requirements and feed formula organized a national science and technology research, "the purpose of" to ", in the period of the small pellets machine price respectively for "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. Proposed the grass carp, black carp, megalobrama amblycephala, carp and Nile tilapia feed formulation and the additive premix formula, introduced the eels and Chinese prawn feed standard (code SCl004-92, respectively, SC2012-94); At present, a number of major fish feed standards are being developed. The feed and additives of turtle, crab, grouper and yellow croaker were studied. At the same time, our country in feed ingredients, processing, machinery, aquatic feed additives as well as the conditions of research and development, test means, quality monitoring, the scientific research team construction, personnel training, all get corresponding development, have the ability to further research and development and the development of industrial production.

In recent years, the price of small feed pellet machines has been advancing rapidly in China's aquatic feed industry, which is directly caused by the continuous high growth of domestic aquaculture industry. As is known to all, China is now the largest aquaculture country in the world, and the only country in the world that produces more aquaculture than fishing. At present, China's total production of aquatic products accounts for about 35% of the global total, among which, the aquaculture output accounts for 2/3 of the global aquaculture output, and has been the world's first for 13 consecutive years. Such a high proportion of aquaculture production is unique among the major fishing powers in the world. China is the country with the largest market capacity of aquaculture in the world. It is precisely because of the huge aquaculture market that China's aquaculture industry has brought huge development space. What is remarkable is that after 1980s, the rapid development of famous aquatic products represented by prawns, eels, turtles and so on has formed a blast of "breeding fever". As one of the material bases for the development of aquaculture industry, the feed processing industry has developed rapidly, and many famous and excellent enterprises have emerged.

According to the 2010 food development program, the per capita share of aquatic products in China will reach 44 kilograms (57.2 million tons) in 2010, but only 33.8 kilograms at present. Therefore, in the next six years, the output of the aquaculture will have a big increase. However, only about 20% of the 25 million tons of aquaculture products produced in China are fed with feed. 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.
