Description

Technical Field

[0001] This utility model relates to the technical field of ergothioneine production equipment, specifically to an ergothioneine production fermentation device. Background Technology

[0002] Ergothioneine is an important bioactive substance with various biological activities such as anti-oxidation, anti-inflammation, and anti-cancer. Ergothioneine is widely found in microorganisms, plants, and animals in nature, especially in fungi. It is widely used in the fields of food, cosmetics, medicine, and health products. Ergothioneine fermentation tanks are used in the production process of ergothioneine.

[0003] In related technologies, ergothioneine fermentation devices often install heating jackets or heat tracing pipes inside the fermentation tank to improve fermentation efficiency and control the temperature within the tank. However, traditional heating jackets, due to the large tank volume, create temperature gradients during reheating, making it difficult to balance heat input. This results in uneven heating during internal stirring, leading to a reduction in fermentation efficiency. While using heat tracing pipes evenly installed on the inner wall of the tank can achieve uniform heating, the number of pipes required increases significantly, raising the equipment's manufacturing cost. To address these issues, an ergothioneine production fermentation device is proposed. Utility Model Content

[0004] In view of this, the present invention provides a fermentation device for ergothioneine production. The present invention uses a motor to drive the stirring shaft to rotate, which in turn drives the positioning ring to rotate, which in turn drives the stirring plate and hollow ball on the stirring assembly to rotate, thereby stirring the liquid in the fermentation tank and improving its mixing efficiency. Simultaneously, the heating power supply is used to power the heat-conducting block, thereby heating the spiral heating tube, which in turn heats the liquid in the stirring process uniformly, thereby improving the fermentation effect of the fermentation tank.

[0005] To solve the above-mentioned technical problems, this utility model provides a fermentation device for ergothioneine production, including a fermentation tank mounted on the upper part of a support frame, a motor mounted on the top of the fermentation tank, a stirring shaft connected to the motor inside the fermentation tank, a positioning ring mounted on the upper and lower parts of the stirring shaft, a stirring component symmetrically mounted on the surface of each positioning ring, and the stirring components being detachably connected to the positioning rings. A spiral heating tube is mounted on the outer side of the stirring component away from the stirring shaft, a pair of limiting rings are mounted on the left and right sides of the spiral heating tube, a heat insulation block is mounted on the side of each limiting ring away from the positioning ring, and a connecting block is mounted on the side of the heat insulation block away from the positioning ring, the connecting block being connected to the inner wall of the fermentation tank.

[0006] A heat-conducting block is installed at the top of the spiral heating tube. The heat-conducting block is used to connect the spiral heating tube to the conduit. The conduit is also installed at the top of the heat-conducting block. The conduit is used to run an electric wire, thereby connecting the heating power supply to the spiral heating tube.

The rotating shaft base is used to fix the stirring shaft, so that the stirring shaft is more stable when rotating. The rotating shaft base is connected to the bottom of the stirring shaft, and the heat insulation sleeve is connected to the upper surface of the cross-shaped positioning plate.

[0009] Each stirring component has a slot corresponding to the positioning ring. The slot is used to receive a pin, thereby connecting the positioning ring to the stirring plate.

One end of the fixing plate is connected to the positioning ring by bolts, and the other end of the fixing plate is connected to the stirring plate by bolts. A hollow ball is provided at the end of the stirring plate away from the stirring shaft. The hollow ball is used to change the flow field distribution at the end of the stirring rod and can also suppress the eddies formed by the stirring plate, thereby reducing the shear force during stirring and thus reducing damage to microbial cells.

[0010] An arc-shaped plate is provided on both the front and back sides of the mixing plate. The arc-shaped plate is used to reduce the deposition of particulate matter on the surface of the mixing plate, thereby suppressing local shear force and reducing damage to microbial cells.

[0011] The bottom of the fermenter is connected to a liquid outlet hopper, which facilitates the flow of liquid from the fermenter into the discharge pipe.
