Description

Technical Field

[0001] The utility model relates to the technical field of fermentation equipment, in particular to a fermentation equipment for producing biological fermented feed. Background Art

[0002] Biological feed takes microbial fermentation technology as the core, and the feed substrate is prepared into animal feed or feed raw materials after biological fermentation. The prepared biological fermented feed improves the utilization rate of roughage and reduces the waste of feed raw materials; through the way of biological feed fermentation, not only can the anti-nutritional factors in the raw materials be removed, the palatability and digestibility of the feed be improved, but also unconventional raw materials can be converted into feed raw materials that animals can digest and absorb, effectively reducing or even replacing the application of antibiotics in the feed and breeding process.

[0003] When fermenting biological feed, the control of temperature is particularly important. If the temperature is too low, the fermentation effect is not good; if the temperature is too high, the fermentation bacterial liquid is easily inactivated. The existing heating devices are prone to cause too high local temperature while the temperature in other positions is relatively low, which is not conducive to the uniform heating and mixing of biological feed production, and extremely reduces its fermentation effect. And before fermentation, the materials need to be crushed. The existing crushing devices have poor crushing effects, and usually need to circulate the feed multiple times to reach the required fineness. To ensure the fineness and uniformity of the feed, the crushed feed often needs to be screened, which is very inconvenient to use. Summary of the Utility Model
