Although many farmers call feed prices rising year after year, but also can not stop the feed industry profit trend. In the past year, even a lot of small and medium-sized feed enterprises have been forced to stop production. The reason is that raw material prices continue to rise, labor costs and other auxiliary costs have increased, the product homogenization is serious, and the competition is intensifying. In this situation, remove the above uncontrollable factors, it was suggested that in the production process to reduce costs, but also feed enterprises "winter" good plan. Perennial committed to feed processing technology and equipment research, supervision division of feed production management, design and implementation of livestock feed America of North Dakota State University professor KimKoch he, introduced American feed enterprises to reduce loss and cost saving method in the production process, lack of reference.
1, receipt of raw materials
Received raw materials into the plant is the first process for feed factory production, is important to ensure the continuity of production process and product quality. The material receiving capacity must meet the need of the production of feed factory, and the use of technology and equipment, advanced application, so as to timely receipt of raw materials, reduce the labor intensity of workers, saving energy, reducing production costs, protect the environment. In the United States, raw materials into the factory to receive this step has been fully mechanized, effectively ensure the efficiency of raw materials into the factory link. Take bulk corn as an example, 1 large trucks can carry 24t corn, and the big truck has two pipes at the bottom. The truck stops at the storage bin automatically and rapidly. The average speed is 3min unloading of 80t corn. In addition, the freight car will be unloaded at the same time, there will be a 360 degree sampler, on the one hand to ensure more reasonable sampling, comprehensive, on the one hand to ensure that "synchronous unloading, synchronous sampling", the domestic still can not do this. Feed factory raw material receiving workload is very large, so the receiving capacity of feed plant receiving equipment is usually 3~5 times of the production capacity of feed factory. But the domestic feed enterprise raw material storage storehouse mostly can not achieve this level, this also is a disturbance raw material receives, the storage one of factors.
2, crushing process
At present mill general mainly has two kinds: hammer mill and roller mill. Hammer mill is more common in China, and it can be divided into half screen type and full screen type. Most hammer mills are vertically rotating, and some are horizontal rotating. They work in a similar way, but the horizontal rotating hammer crusher requires more power. Manufacturers should crush the materials according to the needs of different animals. The principle is to digest and absorb the animals."
3, mixed process
Feed factory mainly rely on mechanical mixing to mixed purpose, therefore, Professor KimKoch introduced the use of foreign mainstream mixing machinery. The most prominent advantages of the horizontal biaxial slurry mixed leaf machine is fast mixing speed, mixing with 1/100000 of the total group trace the feed, each batch only mixed 1min, the degree of uniformity of mixture can achieve uniform quality requirements of the full price of feed. This mixing time is only about 1/3 of the time required for the horizontal screw mixer. Because of the short mixing time, the power consumption per unit output is also low. In addition, the model of the mixing uniformity coefficient of variation is less than 5% CV; the maximum amount of liquid is added up to 20%; full coefficient can be adjusted in the range of 0.4~0.8.
The 4 part, granulation
In granulation process, Professor KimKoch stressed the material moisture content and vapor saturation. He believes that the highest moisture content of materials is 17.5%, to no less than 13% is appropriate. The higher the saturated vapor, the better, but because of the objective conditions, if the saturation can be controlled at 90%, it is the best. However, the current saturated steam in general can only reach 60%~80%. He said, if you can control these two indicators, then the gelatinization of starch will be better, the less anti nutritional factors in feed, feed palatability increased, the meat to meat ratio decreased.
5, storage and transportation links
Pellet durability index PDI (Pellet Durability Index) is one of the indicators to reflect the quality of pellet feed, the most important also, in this part, Professor KimKoch highlighted the problem of moldy feed. He suggested that in addition to control the moisture content of feed bin (such as the moisture content of corn grain classes should be controlled below 13%, moisture content of cake should be controlled below 8%), must also control the relative humidity of not more than 70%, the temperature does not exceed 10 degrees. Once aflatoxin is found in the feed, it should be removed immediately so as not to spread. In short, the entire feed production process, manufacturers should try to achieve effective allocation of resources, in order to achieve the purpose of reducing consumption and cost savings. It mainly includes 3 points, one is to complete the steps in feed production to achieve the ultimate goal, there is no waste; two is to ensure the production effectiveness, no additional loss; three is to ensure the effectiveness of production machinery, manufacturers should have a variety of detailed production data such as tons of machinery. Power consumption, cost reduction is from every seemingly simple and small aspects to the subtle benefits.
