TECHNICAL FIELD
[0001] The utility model relates to the technical field of feed fermentation, in particular to a fermentation tank for biological fermentation feed. BACKGROUND
[0002] Feed is the general term for the food of all animals raised by people, and the general feed mainly refers to the food of animals raised in agriculture or animal husbandry. Feed fermentation is mainly natural fermentation and fermentation with inoculated commercial lactic acid bacteria. Feed treated by fermentation not only improves the nutrient absorption level of feed and degrades the toxins that may exist in feed raw materials, but also greatly reduces the use of antibiotic and other drug additives, and improves the health level of animals.
[0003] For example, a feed production fermentation device with the announcement number CN219689701U includes a fermentation barrel and a detachable cover plate arranged above the fermentation barrel, and further includes a hollow shaft, a stirring column, a liquid distribution cavity arranged in the stirring column, a liquid distribution cavity communicating with the hollow shaft, a liquid outlet hole communicating with the liquid distribution cavity, a check valve mechanism for preventing external liquid and impurities from entering the liquid distribution cavity through the liquid outlet hole, and a liquid inlet pipe for injecting fermentation agents or water into the hollow shaft. In this scheme, the fermentation agents are pumped into the hollow shaft, and the fermentation agents enter the liquid distribution cavity and are sprayed into the fermentation barrel through the liquid outlet hole, so that the fermentation agents can be mixed with feed at different depths and positions, thereby greatly avoiding the situation that the fermentation agents are concentrated in one place and do not fully contact and mix with the feed. Furthermore, the rotation of the stirring column further drives the fermentation agents discharged from the liquid outlet hole to fully and comprehensively mix with the feed, thereby improving the fermentation effect of the feed.
[0004] The above-mentioned patent can improve the fermentation effect of the feed. However, when the feed is subjected to anaerobic fermentation, a large amount of gas is generated during the fermentation between the feed and the microorganisms. Since the inside of the fermentation tank is a sealed environment, the gas pressure inside the device will continuously increase during the fermentation process. In a long-term fermentation process, the fermentation tank may explode, or when the sealing cover is opened, the sealing cover may be sprayed out due to high-pressure gas, which has a high safety risk.
[0005] Therefore, we propose a fermentation tank for biological fermentation feed to solve the above-mentioned problems. UTILITY MODEL CONTENTS
