The influence of feed processing technology on the safety of feed
Effect of feed safety are the major factors to feed raw materials, feed raw materials, formulation of safe storage of various additives quantity control, process control, artificial feed processing technology and reasonable design parameters, appropriate selection of operation process management after processing feed storage management etc.. Only by strictly controlling every link of the processing process can the safe feed be produced.
Control and safe storage of feed raw materials 1, raw material is the first control point safety of feed production, some feedstuffs in the growth process due to the extensive use of pesticides and pest control, greatly exceed the standard of pesticide residues caused by cereal products, feed factory should strengthen the determination of pesticide residues in the receiving of raw materials. In addition, the pollution of waste water and waste gas from industrial production is very serious.
At present, due to the limitation of testing equipment, most of the feed manufacturers do not detect the pesticide residues and industrial pollution raw materials. This is a major hidden danger for safe feed production. Feed producers should pay enough attention to them. Feed raw material moisture is the key to safe storage. Especially for some newly harvested plant materials, moisture is generally not up to the standard of safe storage. During storage, raw materials are highly susceptible to mold contamination, resulting in a large number of mycotoxins, resulting in deterioration of feed quality. Therefore, we need to improve the storage conditions of raw materials and control the moisture content of feed raw materials (less than 12% of safe water), and minimize the contamination of molds, which is the most effective and active way. Many raw materials are not likely to be quite dry due to economic reasons. The mildew fungicide control is an effective measure, but can not remove the existing mildewcide mycotoxins in raw materials, so it must be before the mold pollution as soon as possible mildew control measures.
At present, due to the shortage of feed raw materials, the adulteration of raw materials is very serious, and adulteration of feed raw materials has brought trouble to the production of safe feed. Therefore, when receiving raw materials, we must pass strict tests to confirm whether it is in conformity with the quality standards and resolutely eliminate the unqualified raw materials into the factory.
Most of the ingredients in feed corn, usually stored in silos, especially steel silo, due to easy to cause a big temperature difference between day and night storage of raw material water evaporation and vapor condensation, the silo wall near the part of the raw materials of high water content, such as long-term storage easy to make the raw material to produce mildew. Therefore, the management of the raw materials in the silo should be strengthened, and the moisture of the raw materials can be reduced to ensure the safety of the storage materials.
2, the cleaning of raw materials in feed processing, people often pay attention to the cleaning of large impurities and magnetic impurities in feed raw materials to ensure the safety of feed processing equipment, and the cleaning of small and medium-sized impurities in feed is often neglected. These small impurities are complex, and are the breeding places for all kinds of harmful microbes. When the moisture and temperature of raw materials are suitable for their growth, the nutrition of raw materials is also their medium, making them grow rapidly and produce a lot of harmful substances, which pose a threat to feed safety. Therefore, in the feed production, the small impurities should also be cleared to help the safety of the feed and ensure the quality of the products.
