In recent years, with the rapid development of the grain-saving animal husbandry, various kinds of microbial treatment of straw products have appeared in various places. To produce high-quality microbial strains, the following processes are generally required: Breeding of strains: Because there are hundreds of millions of species of microorganisms, it is necessary to breed fertile straw from these complicated microorganisms, which is beneficial to improve animal milk production, meat production, non-toxic and non-pathogenic. The dominant species is the primary prerequisite for the entire production and the key to the quality of the product. Breeding of strains is a technology with high technology content. Fermentation culture: This section has triangular flask culture, seed tank culture, fermenter culture, and stabilization treatment. High-speed centrifugation: After sealing fermentation and stabilization, in order to collect the concentrated product, the water and the bacteria must be separated by a high-speed centrifuge, and then the separated species are stabilized. Freeze-drying: Freeze-drying is used to ensure the activity of microbial strains. Therefore, the drying of strains cannot be naturally dried, as this will infect other microorganisms and cause a decline in product quality. In order to ensure the activity of microbial strains, it cannot be produced. The milk powder is dried by thermal spray. In general, a freeze-drying device with good performance is expensive and consumes a lot of energy. The costs incurred in this segment account for about 60-70% of the production cost of the entire strain. Viable cell count and biochemical activity test: The number of viable cells and biochemical activity of microbial products should reach a certain amount, in order to ferment in straw fermentation, a large number of bases will be propagated from the beginning, and the added microbial strains will be The entire fermentation process has an absolute advantage. Therefore, the number of live bacteria and biochemical activity is one of the key factors to measure the pros and cons of this product. Compatibility of strains: The compatibility of microbial strains in the same product is also very important, and it is not as simple as blending multiple microbial strains together. Combine several strains together, whether it can be symbiotic, whether there will be no-resistance between various microbial strains, can interact in the straw fermentation process, complement each other, produce the best effect, and at the same time can act on various straws . This is a consideration for the compatibility of microbial strains. In order to enable the majority of users to understand and use this kind of products objectively and rationally, we compare the effects of several types of products on the market from the type and process flow to the use: 1. Liquid product: Because it is not subjected to high-speed centrifugal collection and freeze-drying in the process, such products are liquid. Packaging is generally in the form of plastic drums or plastic bottles. Because it is liquid, there are many problems in the transportation process. It can only be transported by special car or sent to the LTL. The cost of transporting the special car is higher, and the LTL transportation cost of the liquid product is also higher than 20-50% of the general product. The goods are on the road for a long time, and the high temperature and cold will have an adverse effect on the activity of microorganisms. Therefore, the price of liquid products is generally higher than that of solid products, and the higher part is not caused by the technical content of the product and the production process. In addition, because the microorganisms in such products are always in the liquid, it is active and has been continuously breeding and dying, but when the product is in a harsh environment or is left for a long time, the bacteria die. When the quantity exceeds the quantity of reproduction, the product will quickly fail. Therefore, the shelf life of the liquid product does not have a long shelf life of the solid product. In order to reduce transportation costs, some manufacturers build small factories in various places and sell them nearby. It is difficult to guarantee the quality of the product. Second , bran or grass powder as a carrier of solid products: such products due to production process restrictions, can not be microbial collection, concentration, drying, generally use bran or grass powder as a carrier, will contain microorganisms liquid Stir in bran or grass powder, then dry the bran or grass powder and then pack. More than 99% of these products are bran or grass powder. Because of the relatively large packaging volume of these products, they are generally packaged in a separate package of 500-600 grams to process one ton of straw. Because of the special nature of straw feed, the amount of straw processed per treatment is large. When processing silage seasons every year, it is necessary to distribute the products in advance, which is used for a long time in logistics distribution and storage, and the cost is higher. . Therefore, the sales price of such products is not low. In addition, due to the shape of such products, it is not advisable to add to the larger farms and straws Xi'an Jmlai Bio-Tech Co., Ltd. , https://www.jmlaisarms.com
