[0002] Microbial fermentation refers to the process of using microorganisms to convert raw materials into products required by humans through specific metabolic pathways under suitable conditions. The production level of microbial fermentation mainly depends on the genetic characteristics of the strain itself and the culture conditions. The microbial fermentation process is divided into aerobic fermentation and anaerobic fermentation according to the requirements of fermentation conditions. The aerobic fermentation method includes several methods such as liquid surface culture fermentation, fermentation on the surface of porous or granular solid media, and aerobic deep fermentation. Anaerobic fermentation uses deep fermentation without oxygen.

The microbial fermentation device convenient for cooling of this invention drives the rotating shaft and the mixing rods to stir and mix the cooling fermentation material by starting the motor. The cooling effect is good, the cooling rate is fast. After excessive cooling, the first water pump and the heater can be used to pass the heated hot water into the rotating shaft through the first sealing frame, which can relieve excessive cooling.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1 to 5 , the embodiments provided by the present utility model:

[0026] A microbial fermentation external circulation water cooling device, comprising a cooling box 1, inside which a cooling pipeline 2 is assembled. The two ends of the cooling pipeline 2 are respectively provided with a water inlet 3 and a water outlet 4. The water inlet 3 and the water outlet 4 symmetrically penetrate through the surface of the cooling box 1. One end of the cooling box 1 is provided with a mounting frame 5. One side of the mounting frame 5 is provided with a baffle 8. An installation plate 6 is bolted between the inner walls of the mounting frame 5 and the baffle 8. A blowing mechanism 10 is assembled on the surface of the installation plate 6;

[0027] The blowing mechanism 10 includes a fixed seat 101, a fixed frame 102, a centrifugal fan 103 and a heat conducting fin 104. The fixed frame 102 is evenly welded on the surface of the fixed seat 101 in sequence. The fixed frame 102 penetrates through the surface of the installation plate 6 in an inserted manner. The heat conducting fins 104 are evenly arranged on the surface of the fixed frame 102 in sequence. The centrifugal fan 103 is installed on the surface of the fixed seat 101.

[0028] Threaded holes 7 are opened at both ends of the mounting frame 5. Mounting holes are opened at positions corresponding to the two threaded holes 7 at both ends of the baffle 8. The baffle 8 is fixedly connected to the mounting frame 5 through a locking screw 9 in cooperation with the threaded hole 7. By setting the baffle 8 structure, the mounting frame 5 has detachable structural components, which can be disassembled and assembled at any time according to needs, so as to facilitate the maintenance of the overall structure of the device. When in use, the staff needs to manually send the locking screw 9 into the mounting hole and finally screw it with the threaded hole 7 on the mounting frame 5 to achieve an effective shielding structure, so that the main surface of the cooling box 1 is fully protected. Slots are provided on the surface of the mounting frame 5 on one side of the two threaded holes 7. Plug blocks are provided on the surface of the baffle 8 on one side of the two mounting holes. The plug blocks are inserted and fixed with the slots. By setting the connection part with the slot to correspond to the connection part of the baffle 8 for insertion, it can play a certain auxiliary positioning role while achieving a good protection effect, and can be fully fixed before the assembly of the locking screw 9, which is beneficial to the subsequent assembly work, achieving the technical effects of reducing the installation steps and enhancing the installation stability.

[0029] The installation plate 6 includes a first outer shell 61, a second outer shell 62, a compressive layer 63 and a heat insulation layer 65. The compressive layer 63 is laid between the first outer shell 61 and the second outer shell 62. The heat insulation layer 65 is laid between the compressive layer 63 and the second outer shell 62. By setting the first outer shell 61, the second outer shell 62, the compressive layer 63 and the heat insulation layer 65 to realize a layered protection structure, it can provide a good supporting effect during the working process, ensure the safety and stability of the overall work, achieve the technical effect of ensuring the overall strength and stiffness, further guarantee the overall safety, and solve the problem of poor resistance of the box body.

[0030] The surface of the pressure-resistant layer 63 is successively and evenly provided with opening grooves 64, and the areas of the respective opening grooves 64 are the same. The pressure-resistant layer 63 is an integrated structure laid with rubber material, and the heat-insulating layer 65 is an integrated structure laid with fiberglass board. By providing the opening grooves 64, the pressure-resistant layer 63 can have a certain deformation space, and can extend along the position of the opening grooves 64 when being bumped by an external force, playing an auxiliary buffering role, and thus ensuring the overall pressure-resistant and earthquake-resistant effects.

[0031] Baffles are welded on the peripheral surfaces of the fixed seat 101. The four baffles are respectively bolted and fixed to the surface of the fixed frame 102. The four baffles are all in contact with the surface of the mounting plate 6, and one of the baffles is communicated with the air outlet pipe 11. By providing the baffle structure, the sealing performance between the fixed seat 101 and the fixed frame 102 can be ensured, enabling the fixed seat 101 and the fixed frame 102 to be assembled into a box structure on the surface of the mounting plate 6. Furthermore, it can effectively cooperate and assemble with the air outlet pipe 11 on the other side, achieving a good overall protection effect while solving the problem of inconvenient air supply. On one side of the surface of the heat conducting sheet 104, a buckle 105 is bolted. The heat conducting sheets 104 are all clamped and fixed to the surface of the fixed frame 102 through the cooperation of the buckles 105. By providing a plurality of heat conducting sheets 104, the heat conducting effect inside the cooling box 1 can be ensured, enabling the temperature inside the cooling box 1 to be fully diffused to the fixed frame 102 and the fixed seat 101, playing a sufficient cooling effect, so as to facilitate the centrifugal fan 103 to pump and send cold air. During specific use, cold water can be fed into the cooling pipe 2 through the water inlet 3, and then the water inlet 3 can be communicated with the water outlet 4 and circulated with a water pump, so that the inside of the cooling box 1 is fully cooled. Then, the centrifugal fan 103 is used to pump and send cold air out to the air outlet pipe 11, and the air outlet pipe 11 needs to be communicated with the microbial fermentation tank, so that the whole device can provide sufficient cooling treatment for the microbial fermentation tank according to requirements, solving the problem of too low cooling effect due to the small contact area between the rotating shaft and the internal air.
