Feed additives are microbial additives added during feed production and processing to strengthen basic feed nutrition, ensure animal health, save feed costs, and improve animal production performance. The advantage of freeze-drying feed additives is to solve the problem of the retention of microbial active ingredients in additives, to preserve at room temperature, to enhance stability, etc. Feed freeze-drying machine (also known as feed freeze-drying machine) is widely used in probiotic freeze-drying, compound enzyme freeze Dry and other research and development and processing and production.
A large number of microorganisms in feed additives are heat-sensitive substances. Storage in a liquid state requires a specific environment and a short storage time. Other drying methods currently destroy the active ingredients of the substance. The experimental test of the freeze-drying technology shows that the freeze-drying of feed additives uses a feed freeze-drying machine to freeze the raw feed liquid into a solid at a low temperature, and then forms a vacuum environment in the freeze-drying machine chamber, so that the solid ice in the material is directly sublimated into a gas without being liquefied. Remove to obtain feed freeze-dried powder with a water content of less than 1%. During the whole processing process, the feed has been processed in a low-temperature environment and in a vacuum state. The heat-sensitive substances in the material are protected, the growth of the enzyme is restrained, and the oxidation reaction cannot be carried out in a vacuum with poor oxygen. The resolubility of the freeze-dried material is very good.
The freeze-drying of feed greatly preserves the active ingredients in the original material, which is convenient for storage and transportation at room temperature. At present, the feed freeze dryer is being vigorously promoted and applied to ensure the quality and value of feed. It provides choices from laboratory freeze dryers and large-scale production and processing biological product freeze dryers. It is freeze-dried in various feed additives, feed enzymes, Experimental research and development, processing and production of veterinary drugs such as freeze-drying.
