Description

Technical Field

[0001] The utility model relates to the technical field of solid fermentation, and particularly relates to a solid fermentation reactor. Background Art

[0002] Solid-state fermentation refers to a biological reaction process in which one or more microorganisms are used in a water-soluble solid matrix with a certain humidity in the absence or almost absence of free water. Considering the essence of the biological reaction process, solid-state fermentation is a biological reaction process with a gas phase as the continuous phase. Solid-state fermentation has the advantages of simple operation, low energy consumption, easy control of the fermentation process, relatively low requirement for sterility, and less likely to cause large-scale contamination.

[0003] A simple and efficient solid fermentation device disclosed in Chinese Patent CN215050210U includes a tank body. A connecting plate is fixedly connected to the upper end of the tank body. A support plate is fixedly connected to the right end of the connecting plate. A first motor is fixedly connected to the upper end of the support plate. When the first motor rotates clockwise, it can drive the first output shaft and the gear to rotate clockwise. Then, the gear can drive the tooth column, the connecting ring, the water pipe and the spray head to descend. When the first motor rotates continuously counterclockwise and clockwise, it can drive the spray head to rise and fall repeatedly. The repeated rising and falling of the spray head can increase the disinfection area of the circular groove and prevent bacterial mixing.

[0004] When the above-mentioned existing solid fermentation equipment is in use, the second motor rotates to drive the second output shaft and multiple blades to rotate. The rotation of the multiple blades can stir the raw materials in the circular groove. However, the concentration of the water-soluble solid matrix is relatively high, so the fluidity is poor. Only relying on the agitation of the blades cannot efficiently stir the water-soluble solid matrix, resulting in a low mixing efficiency and thus affecting the fermentation effect.

[0005] To solve the above problems, the utility model proposes a solid fermentation reactor. Summary of the Utility Model

[0025] Rotating grooves are respectively provided at the tops of the fermentation chambers inside the reaction tank 1. Sleeves 8 are rotatably sleeved on the outer sides of the connecting rod 4 at positions corresponding to the two fermentation chambers. The tops of the sleeves 8 rotatably penetrate into the corresponding rotating grooves.

[0026] A plurality of stirring rods 9 are fixedly connected to the outer bottom ends of the sleeves 8.

[0027] Linkage components are provided between the tops of the sleeves 8 and the connecting rod 4.

[0028] The linkage components include third bevel gears 7. The third bevel gears 7 are fixedly installed at the tops of the sleeves 8. First bevel gears 5 are fixedly installed on the outer sides of the connecting rod 4 at positions corresponding to the third bevel gears 7. Second bevel gears 6 are rotatably installed inside the rotating grooves. The second bevel gears 6 are respectively meshed with the first bevel gears 5 and the third bevel gears 7.

[0029] Inside the reaction tank 1, water tanks 13 are fixedly installed corresponding to the tops of the fermentation chambers. Rotary nozzles 14 are rotatably installed at the bottoms of the water tanks 13. A water injection pipe 15 is fixedly connected to the water tank 13. The other end of the water injection pipe 15 extends to the outside of the reaction tank 1.

[0030] On the side walls of the reaction tank 1, feed pipes 2 are fixedly connected corresponding to the tops of the fermentation chambers. The feed pipes 2 are inclined.

[0031] On the side walls of the reaction tank 1, discharge pipes 12 are fixedly connected corresponding to the bottoms of the fermentation chambers.

[0035] Working principle:

[0036] During use, different raw materials are poured into the two fermentation chambers through the two feed pipes 2 respectively. The motor 3 is started to drive the connecting rod 4 to rotate. The rotation of the connecting rod 4 drives the rotating cylinder 10 to rotate. At the same time, the connecting rod 4 drives the first bevel gear 5 to rotate, and then drives the third bevel gear 7 to rotate in the reverse direction through the second bevel gear 6, and then drives the sleeve 8 and the stirring rod 9 to rotate in the reverse direction, so that the stirring rod 9 and the rotating cylinder 10 rotate simultaneously and in opposite directions, making the stirring of the raw materials more uniform.

[0037] It should be noted that a brake is installed on the motor 3. The brake pads of the brake cooperate with the braking components on the motor shaft. Through the action of the brake, after each stop of the motor 3, the output shaft of the motor 3 stops at a fixed position; thus, the connecting rod 4 stops at a fixed position; thus, when the motor 3 stops, the through hole 11 corresponds to the discharge pipe 12; after fermentation, the motor 3 is stopped; the valve in the through hole 11 is opened; so that the fermented solid raw materials flow out from the discharge pipe 12.

[0038] The rotary nozzles 14 are opened, and the water in the water tank 13 rotates and sprays out from the rotary nozzles 14, increasing the flushing and disinfection area of the rotating cylinder 10.
