[0029] To make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0030] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, this embodiment provides a microbial fermentation device for producing baked food, including a fermentation cylinder 1, a feeding pipe is provided on the top of the fermentation cylinder 1, a cylinder cover 101 that can be opened and closed is provided on the side wall of the fermentation cylinder 1 near the bottom, and also includes a stirring component and a driving mechanism:

[0031] The stirring assembly includes a box body 2 arranged at the bottom of the fermentation cylinder 1, a rotatable rotating tube 4 penetrating from the box body 2 into the fermentation cylinder 1, a rotating sleeve 3 penetrating from the box body 2 into the fermentation cylinder 1 and rotatably sleeved on the outer wall of the rotating tube 4, a first connecting rod 5 arranged on the side wall of the rotating sleeve 3 and located in the fermentation cylinder 1, a second connecting rod 401 arranged on the side wall of the rotating tube 4 and located in the fermentation cylinder 1, a blade 501 arranged on the rod wall of the first connecting rod 5, and a mixing plate 402 arranged on the rod wall of the second connecting rod 401;

[0032] The driving mechanism includes a motor 6, two driven bevel gears 7 and a driving bevel gear 601 connected to the output end of the motor 6.

The driving bevel gear 601 is meshed with the two driven bevel gears 7 to drive the two driven bevel gears 7 to rotate in opposite directions.

[0033] When the present embodiment is in use, food raw materials and microorganisms are first put into the fermentation barrel 1 through the feed pipe, and the two are allowed to contact and ferment; at the same time, the motor 6 can be started to drive the active bevel gear 601 to rotate, and the active bevel gear 601 will drive the relative reversal of the two driven bevel gears 7, so that the rotating sleeve 3 and the rotating tube 4 are relatively reversed, and finally the blades 501 on the rotating sleeve 3 and the mixing plate 402 on the rotating tube 4 are relatively reversed, so that the raw materials and microorganisms can be stirred in different directions, and the contact strength between the raw materials and the microorganisms can be increased, thereby increasing the fermentation reaction speed of the raw materials. Finally, the fermented food raw materials in the fermentation barrel 1 can be taken out and used by opening the barrel cover 101.

[0034] like Figure 3 and Figure 4 As shown, as an improvement, on the basis of the above embodiment, the inner wall of the fermentation cylinder 1 is provided with a gear ring 8 arranged in the circumferential direction, the tube wall of the rotating sleeve 3 is provided with a radially-arranged adapter hole, one end of the first connecting rod 5 is rotatably plugged into the adapter hole and the other end is provided with a gear 502 meshing with the gear ring 8, and the rotation axis of the first connecting rod 5 is along the radial direction of the rotating sleeve 3; in addition, the blade 501 on the first connecting rod 5 is preferably spiral-shaped;

[0035] The mixing plate 402 is horizontally arranged on the rod wall of the second connecting rod 401, and a baffle 9 is fixedly arranged on the inner wall of the fermentation cylinder 1 in the vertical direction, and a through groove for the mixing plate 402 to pass through is opened on the side wall of the baffle 9;

[0036] When the rotating sleeve 3 rotates, on the one hand, the first connecting rod 5 will rotate around the axis of the rotating sleeve 3 driven by the rotating sleeve 3, and on the other hand, since the gear 502 rolls along the gear ring 8 driven by the first connecting rod 5, the first connecting rod 5 will rotate around its own axis, and then the first connecting rod 5 can drive the blade 501 to rotate around the axis of the rotating sleeve 3, and can also rotate around the axis of the first connecting rod 5, so that the blade 501 can form a multi-directional composite motion, improve the effect of stirring and crushing the raw materials and microorganisms, and accelerate the mixing reaction speed; at the same time, when the rotating tube 4 rotates, the mixing plate 402 will continuously pass through the slot on the surface of the baffle 9, which is convenient for cutting and dispersing the raw materials, and further improves the mixing reaction speed of the raw materials and microorganisms.

[0037] like Figure 1 and Figure 2As shown, as a further improvement, on the basis of the above embodiment, it also includes a support assembly, which includes a support frame 14 and rotating columns 15 respectively connected to both sides of the support frame 14 in a horizontal rotation manner, and the fermentation cylinder 1 is connected between the two rotating columns 15. A torsion spring 1501 is sleeved on the rotating column 15, and the torsion spring 1501 is arranged between the fermentation cylinder 1 and the support frame 14 and is used to push the fermentation cylinder 1 to reset; a fixing bolt is provided on the support frame 14, which acts on the rotating column 15 to limit the rotation angle of the rotating column 15, and the fixing bolt is preferably a bolt, and a vertical screw hole is provided on the outer peripheral wall of the rotating column 15. When the fixing bolt is screwed to the screw hole, the rotation angle of the rotating column 15 can be locked, and the fermentation cylinder 1 is kept in a state where the axis is along the vertical direction;

[0038] In addition, the bottom of the fermentation cylinder 1 may be further connected to a weighted ball 1601 via a hanging rope 16;

[0039] When the raw materials and microorganisms in the fermentation cylinder 1 are stirred, the bolt is rotated to separate it from the rotating column 15. At this time, the fermentation cylinder 1 can be pushed back and forth to allow the fermentation cylinder 1 to swing back and forth around the rotating column 15 on the support frame 14; and the torsion spring 1501 applies a torsional force to the fermentation cylinder 1 to facilitate the reset of the fermentation cylinder 1 after the swing back and forth; in addition, the counterweight ball 1601 can be set to make the fermentation cylinder 1 automatically swing for a longer time under the action of gravity, so that the raw materials and microorganisms in the fermentation cylinder 1 can be shaken, and the mixing reaction speed of the two can be further improved; after the stirring operation is completed, the fermentation cylinder 1 can be fixed relative to the support frame 14 by straightening the fermentation cylinder 1 and screwing the bolt into the screw hole of the rotating column 15 again.

[0040] like Figure 4 and Figure 6 As shown, as a further improvement, on the basis of the above embodiment, an air supply assembly is further provided inside the fermentation cylinder 1, the air supply assembly includes an exhaust pipe 10 and an air intake connector, the air intake connector is connected to the rotating pipe 4 and supplies air to the rotating pipe 4, one end of the exhaust pipe 10 is connected to the rotating pipe 4 and the other end passes through the rotating sleeve 3 and extends into the fermentation cylinder 1, and a plurality of exhaust heads 1001 distributed along the axial direction are provided on the lower side of the exhaust pipe 10;

[0041] The air inlet connector includes an adapter sleeve 12 rotatably sleeved outside the rotating sleeve 3 and an air inlet pipe 11 having one end connected to the adapter sleeve 12 and the other end extending outward through the fermentation cylinder 1. A ventilation groove 1201 is provided inside the adapter sleeve 12, and air inlets 13 are provided at positions of the rotating sleeve 3 and the rotating tube 4 corresponding to the ventilation groove 1201.

[0042] When in use, sterile air is introduced into the ventilation groove 1201 inside the adapter sleeve 12 through the air inlet pipe 11, and the sterile air continues to flow into the rotating pipe 4 through the air inlet 13, and then blown into the fermentation cylinder 1 from each exhaust head 1001 through the exhaust pipe 10. The rotating sleeve 3 will drive the exhaust pipe 10 to rotate, so that the sterile air can be evenly discharged into various positions inside the fermentation cylinder 1, which is convenient for more uniform contact between the sterile air and the raw materials, thereby increasing the reaction and fermentation speed of the raw materials. Moreover, because the adapter sleeve 12 is rotatably connected to the rotating sleeve 3, the rotating sleeve 3 will not drive the adapter sleeve 12 and the air inlet pipe 11 to rotate when rotating, so it will not affect the air intake.

[0043] Among them, a filter cover is provided at the bottom of the exhaust head 1001; the filter cover can prevent the raw materials in the fermentation cylinder 1 from entering the exhaust head 1001 and causing air path blockage.

[0044] Although the disclosure is as above, the protection scope of the disclosure is not limited thereto. For those skilled in the art, various changes and modifications can be made without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the protection scope of the utility model.
