collision between fermented feed bag and one way degassing valve

Wojin plastic production factory adopts the production technology of respiratory bag to produce fermented feed bag, which can achieve 100% exhausting effect of microbial feed products. In this way, it is easy to produce and maintain the active state of microbial feed in the process of production, usage and storage, so as to guarantee the activity of microorganisms to the maximum extent. It not only is a perfect solution to the problem of bagging technology in the packaging and transportation of microorganisms, but also allows the microbes to play a role in the greatest extent. At present, it is commonly used in fermented feed bag, breathing membrane bag, fermentation degassing bag, fermentation breathing bag.

The key technology of fermented feed bag is that the unity model relates to a life breathing device which ensures high activity of microorganism – respiratory membrane. Some people ask, what is a respiratory membrane? Actually respiratory membrane is fermented feed bag plus one way degassing valve. The device allows live (mainly lactobacillus and yeast) to remain naturally activity in the packaging bag for a long time. After inoculation, the raw materials are sealed in the packaging bag and the fermentation is carried out in the bag. When the gas produced by the microorganisms in the process of fermentation has reached a certain pressure, it will be discharged through the one way degassing valve, but the outside air can’t enter into the bag. What is more, it ensures that the environment in the bag is free from oxygen and living contaminants, which not only ensures the activity of the microorganism, but also ensures the long-term storage and transportation of the product. Obviously, this innovative technique of first packaging and then fermentation has solved the problem of heat dissipation, anaerobic control and packaging, storage, transportation and stability of microbial solid fermentation, greatly reducing the production, cost of microbial fermented feed.

High efficiency respiratory membrane solid fermentation technology has effectively solve the technical problems of temperature, humidity, and PH value control in the process of microbiological fermentation treatment of light industry by-products, like soybean residue, corn syrup, wine grains, vinegar residue, fruit residue, and agricultural by-products with high nutritional resistance, like cotton-seed meal, rapeseed meal. In this way, the aerobic fermentation and anaerobic fermentation can be carried out in the same environment. The combination of inoculated microorganisms can effectively inhibit and kill Escherichia coli and salmonella, and at the same time, it can promote the rapid growth of lactic acid bacteria.

By using microorganisms to treat the physical and chemical propertied of bulk feed raw materials such as fermentation, trace raw materials which are difficult to use can increase palatability, improve digestibility and nutritional value, or detoxify the material and accumulate beneficial substances. This category includes lactic acid fermentation (silage), coarse feed fermentation, basidiomycete fermentation, fecal fermentation, slaughter residue fermentation, detoxification of poisonous feed, detoxification of cake etc.

By adopting combined fermentation method of yeast, lactobacillus and bacillus, combined with respiratory membrane device, which can automatically adjust the pressure, the technology of producing high living bacteria biological feed by mobile solid fermentation has been successfully realized through repeated tests.

After the inoculation, the raw materials are directly put into the packaging bag which is attached with a balance membrane to regulate pressure and the fermentation is carried out at room temperature after sealing. No temperature adjustment is required, nor is it affected by ambient temperature in the fermentation process. The time required for fermentation maturation varies with ambient temperature and material composition. But the expiration date is not bound by time. As long as the packaging is excellent without damage, the shelf life can be up to 3 years. Air pressure balancing membrane device has creatively solved the technical problems of gas control and contamination with miscellaneous bacteria in the process of fermentation production.

The fermented feed bag has solved the problem of the cohabitation of the bacteria which has been troubled for a long time in the field of microbial fermentation. Generally, the Pichia pastoris and lactobacillus can’t coexist in the fermentation process. But the problem is easily solved by respiratory membrane device. Wojin fermented feed bag is made of PE composite PA material and seven layers of nylon co-extrusion composite film. It has the features of high transparency, good toughness, difficulty in breakage and good heat-sealing effect.
