[0037] The fermentation device further comprises a heating component, which comprises a heating tube 4 located in the air-avoiding area 3 , and the heating tube 4 rotates circumferentially around the inner tank 2 in the air-avoiding area 3 .

[0038] By providing an outer tank 1 and an inner tank 2 and providing an air avoidance zone 3 between the outer tank 1 and the inner tank 2, and providing a heating tube 4 in the air avoidance zone 3, the heating tube 4 is located outside the inner tank 2, and the air avoidance zone 3 formed between the inner wall of the outer tank 1 and the outer wall of the inner tank 2 can prevent the heat of the heating tube 4 from being lost, so that the heat is distributed in the air avoidance zone 3, thereby achieving effective heating of the inner tank 2. The heating tube 4 rotates circumferentially around the inner tank 2 to achieve uniform heating or heat preservation effect at various positions of the inner tank 2, which is beneficial to uniform temperature at various locations of the inner tank 2, thereby facilitating the fermentation quality of soybean paste.

[0039] In addition, since the heating tube 4 is arranged outside the inner tank 2, on the one hand, it does not contact the material inside the inner tank 2, thereby preventing the material from sticking to the heating tube 4 and affecting the heating effect, and at the same time preventing the material from not being cleaned in time and effectively and breeding bacteria on the outside of the heating tube 4; on the other hand, the heating tube 4 is in the air avoidance area 3, and the heating tube 4 and the inner tank 2 can be disassembled and assembled separately without affecting each other. Compared with the method of fixing the heating component on the inner wall of the heating chamber, the heating tube 4 is arranged in the air avoidance area 3, which has a large installation space, a simpler installation method, low operating difficulty, and is easy to disassemble and repair.

[0040] like Figures 1 to 3 As shown, in one embodiment, the heating assembly further includes a rotating disk 5 located at the bottom of the inner tank 2, the heating tube 4 is fixed to the top of the rotating disk 5, and the rotating disk 5 rotates circumferentially around its own central axis to drive the heating tube 4 to rotate.

[0041] The heating tube 4 is driven to rotate around the inner tank 2 by setting a rotating disk 5. The rotating disk 5 is located at the bottom of the inner tank 2, does not affect the structure of the inner tank 2, and is conducive to the stable rotation of the heating tube 4, avoiding displacement of the heating tube 4 and causing damage or collision noise.

[0042] It should be noted that the connection between the inner tank 2 and the outer tank 1 can be achieved by a detachable connection method in the prior art, and no specific limitation is made thereto. For example, a bracket facing inward is provided on the top of the outer tank 1, and a lug facing outward is provided on the outer wall of the inner tank 2. When the inner tank 2 is placed inside the outer tank 1, the lug abuts against the bracket, thereby achieving the connection between the outer tank 1 and the inner tank 2.

[0043] like Figure 2 , Figure 3 As shown, in one embodiment, the heating component further includes a base 6 having a connection port 62 , and the heating component further includes a drive motor 8 , and an output shaft 81 of the drive motor 8 passes through the connection port 62 and is transmission-connected to the bottom of the rotating disk 5 .

[0045] In addition, if Figure 3 As shown, in a preferred embodiment, the rotating disk 5 is arranged at a through hole corresponding to the connection port 62, the stirring assembly includes a stirring rod 7, and the output shaft 81 of the driving motor 8 passes through the connection port 62 and the through hole in sequence and is connected to the stirring rod 7. The output shaft 81 is sequentially connected to the rotating disk 5 and the stirring rod 7, and while driving the rotating disk 5 to rotate, the stirring rod 7 is driven to rotate to achieve the stirring function.

[0046] Furthermore, if Figure 2 As shown, the bottom wall of the outer tank 1 is provided with a through hole 12 aligned with the connecting port 62 , and the base 6 abuts against the inner bottom wall of the outer tank 1 , or the base 6 is fixed to the inner bottom wall of the outer tank 1 .

[0047] The base 6 abuts against the inner bottom wall of the outer tank 1 , further improving the overall force strength and stability of the device, which is conducive to achieving stable rotation of the rotating disk 5 .

[0048] Or, if Figure 2 As shown, the bottom wall of the outer tank 1 is provided with an air-avoiding opening 11 , and the base 6 is arranged at the air-avoiding opening 11 .

[0049] Preferably, the inner diameter of the air escape 11 is smaller than the outer diameter of the base 6 , and the outer bottom wall of the base 6 abuts against the inner bottom wall of the outer tank 1 , or the outer bottom wall of the base 6 is fixed to the inner bottom wall of the outer tank 1 .

[0050] The inner diameter of the air avoidance 11 is set to be smaller than the inner diameter of the base 6.

If the base 6 abuts against the outer tank 1, it can prevent the base 6 from being displaced and falling due to rotational vibration. If the base 6 is fixed to the outer tank 1, it is convenient to realize the connection of the base 6 in the outer tank 1 at the air avoidance 11.

[0051] like Figure 2 , Figure 3 As shown, in one embodiment, the diameter of the base 6 is larger than the diameter of the rotating disk 5. This is beneficial to strengthen the force strength of the base 6, ensure the rotation stability of the rotating disk 5, and prevent the rotating disk 5 from slightly deviating during the rotation process and sliding out of the base 6, resulting in skewness and instability during rotation.

[0052] like Figure 2As shown, in one embodiment, the base 6 is provided with a groove 61, the rotating disk 5 is located in the groove 61, the groove 61 is provided with an arc-shaped side wall, and the curvature of the arc-shaped side wall is the same as the curvature of the side wall of the rotating disk 5. The limiting effect of the base 6 on the rotating disk 5 is strengthened to ensure that the position of the rotating disk 5 is stable during rotation.

[0053] In one embodiment, a plurality of heating tubes 4 are provided, and the plurality of heating tubes 4 are evenly distributed along the circumference of the rotating disk 5. The plurality of heating tubes 4 is conducive to increasing the heating temperature rise rate, and the circumferentially even distribution is conducive to making the inner tank 2 evenly and stably heated as a whole during the rotation process.

[0054] In one embodiment, the heating assembly further includes a power cord connected to the heating tube 4 , and an outer wall of the outer tank 1 is provided with a control switch connected to the power cord.

[0055] Furthermore, a control switch is arranged on the outer wall of the outer tank 1 to facilitate switch operation, the interior of the rotating disk 5 is arranged to be hollow, the power cord is arranged inside the rotating disk 5, and an opening is arranged on the rotating disk 5 to allow the power cord to pass through, and an opening is arranged on the outer tank 1 to connect the power cord to the control switch.

[0056] Alternatively, a control system and a controller are provided, which are connected to the control switch and the heating component via electrical signals to achieve wireless control.

[0057] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0058] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0059] The above is only an embodiment of the present application and is not intended to limit the present application.
