Description

Technical Field

[0002] The feed treated by fermentation not only has the advantages of improving the feed nutrition absorption level and degrading the possible toxins in the feed raw materials, but also can greatly reduce the use of drug additives such as antibiotics, improve the animal health level, and thus improve the food safety of animal products.

[0003] Feed fermentation mostly adopts two methods: natural fermentation and fermentation by inoculating commercial lactic acid bacteria and other strains. The feed produced by natural fermentation generally has unstable quality and is easily infected by miscellaneous bacteria. The fermentation mixing device in the prior art adopts the artificial fermentation method, but the fermentation temperature inside it is not easy to control, and the heat cannot be quickly and evenly transferred to every part of the raw materials. Content of the Utility Model

[0004] The purpose of the utility model is:

[0005] To solve the problem that the heat transfer of the feed fermentation mixing device in the prior art is uneven, resulting in different fermentation temperatures at different parts of the raw materials and affecting the fermentation effect, a mixing device for preparing biological fermentation feed is provided.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A mixing device for preparing biological fermentation feed includes a device housing, an inlet pipe and an outlet pipe are connected to the device housing, a mixing motor is installed above the device housing, a mixing stirrer is connected to the bottom end of the mixing motor, the mixing stirrer extends into the device housing, a solid-liquid separation filter screen is installed at the bottom inside the device housing, a heating device is connected to the inner wall of the device housing, and the heating device is electrically connected to a temperature display and a temperature control button installed on the outer wall of the device housing.

[0008] Further, the heating device includes a support frame connected to the inner wall of the device housing, two rotating electrical connectors are connected to the support frame and arranged up and down, and a rotating electric heating wire is connected between the rotating electrical connectors.

[0009] Further, a sterilizing liquid storage tank is installed on the top surface of the device housing, a sterilizing liquid spraying mechanism is communicated with the bottom of the sterilizing liquid storage tank, and the sterilizing liquid spraying mechanism is installed at the top inside the device housing.

[0010] Furthermore, a fermentation liquid inlet pipe is installed on the device housing. One end of the fermentation liquid inlet pipe located inside the device housing is connected with a universal nozzle, and the end of the fermentation liquid inlet pipe located outside the device housing is connected with a fermentation liquid storage tank.

[0011] Furthermore, a drain pipe is connected to the bottom of the device housing. A switch valve is installed on the drain pipe, and a heat preservation jacket is sleeved outside the device housing.

[0012] To sum up, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0013] The present utility model uses a built-in heating device and a temperature control device that can display and control to precisely control the temperature inside the fermentation mixing device. Compared with the device in the prior art that uses the method of blowing hot air to heat and increase the fermentation temperature, the method of heating from the inside adopted by the present utility model is more convenient for temperature control. The heat is transferred evenly from the inside of the raw material to the outside, rather than from the outside to the inside, significantly improving the degree of uniform distribution of heat during the fermentation of the raw material, effectively enhancing the efficiency and effect of heat generation, making the fermentation of the raw material more thorough and the utilization rate higher.

After the sterilization is completed, the sterilizing liquid is discharged from the bottom drain pipe 18 through the solid-liquid separation net, and then the fermentation liquid storage box 17 sprays the fermentation liquid into the device through the universal nozzle 16. The mixing motor 4 is turned on to drive the mixing agitator 5 to fully mix the fermentation liquid and the raw materials. At the same time, the heating device 7 is turned on, and the temperature sensor of the heating device 7 transmits information to the temperature display 8 to observe the internal temperature, and the temperature control button 9 is used to adjust the heating power of the heating device 7, so as to adjust it to a suitable fermentation temperature. After the fermentation time is completed, the fermented product is discharged from the discharge pipe 3, and the fermented liquid enters the drain pipe 18 through the bottom solid-liquid separation filter 6 and is discharged by the switch valve 19.
