In addition, because of the shape of these products, it is not appropriate to add larger farms and straws.
Comparison of Processes for Treating Straw Products by Several Microorganisms
In recent years, with the rapid development of the grain-saving animal husbandry, there have been various types of microbial treatment of straw products. To produce high-quality microbial strains, it is generally necessary to go through the following process: Breeding of strains: Since microorganisms have hundreds of millions of genera, it is necessary to select suitable cultivars of fermented stalks from the complex microorganisms to improve animals. The predominant bacteria producing milk, producing meat, non-toxic and non-pathogenic are the primary preconditions for the entire production and the key to the quality of the product. Breeding of strains is a technology with high technological content. Fermentation culture: This section includes the flask culture, seed tank culture, fermenter culture, and stabilization. High-speed centrifugation: After sealing the fermentation and stabilizing it, in order to collect the concentrated product, a high-speed centrifuge must be used to separate the water from the bacteria, and then the isolated bacteria should be stabilized. Freeze-drying: Freeze-drying is used to ensure the activity of microbial strains. Therefore, natural drying cannot be used for the drying of strains because it can infect other microorganisms and result in a decline in product quality. To ensure the activity of microbial strains, it cannot be produced as well. Heat spray drying is used for milk powder. In general, a good freeze-dried device has a higher price and consumes more energy. The cost incurred in this link accounts for about 60-70% of the total strain production cost. The number of viable cells and biochemical activity test: The number of viable cells and biochemical activity of the microbiological product should reach a certain amount, so that in the fermentation of straw, a larger number of bases can reproduce geometrically from the beginning, allowing added microbial strains to grow. The absolute advantage of the entire fermentation process. Therefore, the number of viable cells and biochemical activity is one of the keys to measuring the pros and cons of this product. The compatibility of strains: The compatibility of microbial strains in the same product is equally important and not as simple as blending multiple microbial strains together. By combining several strains together, whether or not they can coexist, no antibiotics will occur between various strains of microorganisms. They can interact and complement each other during the process of straw fermentation to produce the best results. At the same time, they can also act on various kinds of straw. . This is the compatibility of microbial strains to be considered. In order for the majority of users to objective and rational understanding and use of such products, we will be on the market several products from the more common patterns and the impact on the process used to make a comparison: First, the liquid product: As in the process flow, Without high-speed centrifugation and freeze-drying, these products are liquid. Plastic packaging or plastic bottles are generally used for packaging. Because it is a liquid, there are many problems in the transportation process. Only special vehicles can be transported or send a LTL. The cost of special vehicles is high, and the LTL transportation cost of liquid products is also about 20-50% higher than that of general products. The long time the goods are on the road, the high temperature and coldness will have adverse effects on the activity of microorganisms. Therefore, the price of a liquid product is generally higher than that of a solid product, 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. However, when the product is in a relatively harsh environment or a long period of time, the bacteria will die. When the quantity exceeds the number of reproductions, the product will quickly fail, so the shelf life of the liquid product does not have a long shelf life. In order to reduce transportation costs, some manufacturers built small factories around the country to produce and sell them nearby. This is difficult to ensure product quality. Second, the bran or grass powder as a carrier of solid products: Such products due to the limitations of the production process, can not be microbial collection, concentration, drying, generally use bran or grass powder as carrier, the liquid containing microorganisms Stir in wheat bran or grass flour, then dry the bran or grass powder and pack it. More than 99% of such products are bran or grass powder. Since the packaging volume of such products is relatively large, they are generally packaged separately in 500-600 grams to treat one ton of straw. Because of the special nature of straw feed, the amount of straw to be processed each time is large. To process the silage season each year, it is necessary to deliver products in advance. The time spent on logistics distribution and storage is longer and the cost is higher. . Therefore, the sales price of such products is not low.
