Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fermentation, in particular to a ton bag used for feed fermentation. Background Art
[0002] Fermentation with breathing bags is a major production method for fermented feed. The key technology for producing fermented feed with this method is the breathing valve set on the breathing bag. The characteristic is that the gas in the fermentation bag can be discharged from the bag through the breathing valve, while the gas outside the fermentation bag cannot enter the fermentation bag, which effectively avoids the contamination of the fermented material caused by external bacteria entering the fermentation bag. However, the microorganisms are tiny, mostly measured in microns. In order to effectively block the microorganisms, the pore size of the breathing valve filter membrane is mostly around 0.45um. The problem caused by this is that the resistance to gas discharge is large, so that the fermentation gas in the fermentation bag cannot be discharged smoothly and fully, and remains in the fermentation material. The gas produced by fermentation is part of the microbial metabolites, and the metabolites have a feedback inhibitory effect on the microorganisms. In particular, the CO2 produced by fermentation cannot be effectively discharged. It accumulates in the fermentation system and turns into carbonic acid. Carbonic acid can inhibit the growth of microorganisms and even cause the death of microorganisms. In this way, the microbial strains in the fermentation system cannot fully grow, reproduce and metabolize, resulting in the obstruction of the fermentation activity of the fermentation bacteria and the lack of effective metabolites, which affects the quality of the final fermented feed.
[0003] In order to reduce the discharge resistance of gas generated by fermented feed when using the breathing bag process to produce fermented feed, ensure that the fermentation gas in the fermentation bag can be discharged smoothly, and thus ensure that the quality of the final fermented feed is not affected, it is very necessary to develop a ton bag for feed fermentation.

[0070] The utility model discloses a method for using a ton bag for feed fermentation:
[0071] The first bag opening 301 of the first bag body 1 and the second bag opening 302 of the second bag body 2 are opened in sequence, and the liquid 12 (the liquid 12 can be clean water or an alkaline solution or a gas absorption liquid, etc.) is introduced into the interior of the container 10, so that the air outlet of the air guide tube 9 is immersed below the liquid level of the liquid 12 in the container 10, and the fermented feed that has been inoculated with the microbial fermentation liquid is loaded into the interior of the second bag body 2 from the second bag opening 302 of the second bag body 2, and the second bag opening 302 of the second bag body 2 is directly or indirectly fastened by the fastener 4 to prevent the gas inside the second bag body 2 from leaking out of the second bag opening 302 of the second bag body 2; if there is a need for transportation, the first bag body 1 can be lifted and transported more conveniently by the sling 26, and then the second bag body 2 therein can also be transported and transported, so that the ton bag for feed fermentation of the utility model can be transported to a designated site.
[0072] The ton bag for feed fermentation of the utility model which has been filled with the feed to be fermented is subjected to static fermentation treatment. Since the connection contact surface between the exhaust connection device and the bag wall of the second bag body 2 is sealed stably and firmly without air leakage, the airtightness of the second bag body 2 is guaranteed. When gas is generated during the fermentation process, the air pressure in the second bag body 2 increases, and the gas generated by the fermented feed can only pass through the exhaust connection device and the air duct 9 into the liquid 12 in the container 10. The air duct 9 and the liquid 12 in the container 10 form a water seal structure, and the liquid 12 can also be used as an absorption liquid to absorb the discharged gas. The production staff can judge the state and degree of feed fermentation by observing the state changes of the liquid 12 in the container 10 (for example: color changes, bubbling changes, turbidity changes and other sensory changes visible to the naked eye); the air outside the second bag body 2 cannot enter the second bag body 2 from the air duct 9. The inside of the bag body 2 ensures that the fermented feed inside the second bag body 2 is not contaminated by external bacteria, and the gas generated during the fermentation process can be discharged outside the second bag body 2 without resistance, thereby avoiding the metabolic gas feedback inhibiting the metabolism and growth and reproduction of microorganisms during the fermentation process of the fermented feed. In particular, there is no inhibition or damage to the microbial strains by carbonic acid caused by the accumulation of CO2, which can ensure the sufficient growth, reproduction and metabolism of the microbial strains in the fermentation system of the fermented feed in the second bag body 2, and finally the number of microbial strains and their metabolites in the fermented feed product can be effectively increased, thereby improving the quality of the fermented feed.
[0073] After fermentation is completed, the fastener 4 can be unfastened, and the first bag opening 301 of the first bag body 1 and the second bag opening 302 of the second bag body 2 can be opened in sequence to take out the fermented feed product in the second bag body 2.
