[0039] In this embodiment, during use, the material to be fermented is discharged into the inner cavity of the fermentation tank body 1 through the feed pipe 4. During this process, the material can be stirred by the stirring mechanism, thereby effectively improving the uniformity of the material during transportation. At the same time, the material at the bottom of the inner cavity of the fermentation tank body 1 is guided to the upper part of the inner wall of the fermentation tank body 1, and the inner wall of the fermentation tank body 1 is scraped, thereby effectively preventing impurities generated by fermentation from adhering to the inner wall of the fermentation tank body 1.

[0040] At this time, through the stirring mechanism, sterile air can be evenly discharged into the inner cavity of the fermenter body 1 by the gas supply pipe 6, and the thrust generated when the sterile air is discharged will scrape the bottom of the inner wall of the fermenter body 1. This can provide sufficient oxygen to the microorganisms while avoiding the precipitation of impurities during the fermentation process, thereby further improving the efficiency of mass and heat transfer of materials during the fermentation process, and effectively reducing the energy consumption required during the use of the fermenter body 1.

[0041] When the material has finished fermenting, the electric valve is opened by an external controller, so that the fermented material can be transported to the subsequent device for further processing through the discharge pipe 5.

[0042] In one embodiment, such as Figures 1-5 As shown, the stirring mechanism includes: a first stirring component disposed on the fermenter body 1;

[0043] The first stirring assembly includes: a stirring rod 203 disposed inside the fermenter body 1, the stirring rod 203 extending to the outside of the top of the top cover 3, the stirring rod 203 being located below the gas supply pipe 6, the stirring rod 203 being rotatably connected to the top cover 3, and multiple sets of stirring plates 202 being fixedly connected circumferentially at equal intervals to the outer wall of the stirring rod 203.

[0047] In one embodiment, such as Figures 2-4 As shown, the second stirring assembly includes: a connecting cylinder 205 disposed below the stirring rod 203; multiple arc-shaped scrapers 204 are fixedly connected to the outer wall of the connecting cylinder 205 at equal intervals around the circumference; the outer walls of the multiple arc-shaped scrapers 204 are in contact with the inner wall of the bottom end of the fermentation tank body 1; gas delivery grooves 209 are opened inside the multiple arc-shaped scrapers 204; the gas delivery grooves 209 are interconnected with the inner cavity of the connecting cylinder 205; multiple nozzles 206 are installed at one end of the multiple arc-shaped scrapers 204; exhaust holes are opened at the ends of the arc-shaped scrapers 204 located at the nozzles 206; the inner cavities of the exhaust holes are interconnected with the inner cavities of the nozzles 206 and the gas delivery grooves 209, respectively.

[0048] A conveying assembly is provided on the connecting cylinder 205;

[0049] The conveying component is a connecting pipe 2012 fixedly connected to the top of the connecting cylinder 205. The connecting pipe 2012 extends to the outside of the top of the stirring rod 203. The connecting pipe 2012 is rotatably connected to the stirring rod 203. The inner cavity of the connecting pipe 2012 is in communication with the inner cavity of the connecting cylinder 205.

[0050] A support assembly is provided on the connecting pipe 2012;

[0051] The support assembly includes: a support ring 2010 fixedly connected to the outer wall of the connecting pipe 2012, the support ring 2010 slidably sleeved on the outer wall of the limiting ring 7, and a plurality of balls 2011 rotatably connected to the bottom end of the support ring 2010 at equal intervals in the circumference. The plurality of balls 2011 are in contact with the upper surface of the stirring rod 203. Through the cooperation of the second stirring assembly, the conveying assembly and the support assembly, the inner wall of the bottom end of the fermenter body 1 can be scraped by the thrust generated when sterile air is discharged, thereby effectively preventing the sedimentation of impurities.

[0052] A transmission assembly is provided on the stirring rod 203;

[0053] In one embodiment, such as Figures 1-5 As shown, the transmission assembly includes: a bevel gear ring 2013 fixedly connected to the outer wall of the stirring rod 203, the bevel gear ring 2013 being located above the top cover 3, and a bevel gear 2014 meshing with the outer wall of the bevel gear ring 2013;

[0054] A drive assembly is provided on the top cover 3;

[0055] The drive assembly includes a support plate 2015 fixedly connected to the top of the top cover 3. The support plate 2015 is located at the end of the bevel gear 2014 away from the stirring rod 203. A motor 201 is installed at the end of the support plate 2015 away from the bevel gear 2014. The output end of the motor 201 is fixedly connected to the bevel gear 2014. Through the cooperation of the transmission assembly and the drive assembly, rotational power can be provided to the stirring rod 203.

[0056] The above embodiment discloses a fermenter with anti-sedimentation effect. In use, the material to be fermented is discharged into the inner cavity of the fermenter body 1 through the feed pipe 4. During this process, the motor 201 drives the bevel gear 2014 to rotate. At this time, the bevel gear ring 2013 drives the stirring rod 203 to rotate under the meshing of the bevel gear 2014. At the same time, multiple sets of stirring plates 202 can stir the material under the drive of the stirring rod 203, thereby effectively improving the uniformity of the material during transportation. Meanwhile, the two fixed frames 208 drive multiple spiral scrapers 207 to move under the drive of the stirring rod 203. In this way, the material at the bottom of the inner cavity of the fermenter body 1 can be guided to the upper part of the inner wall of the fermenter body 1 through the multiple spiral scrapers 207, and the inner wall of the fermenter body 1 can be scraped. This can effectively prevent impurities generated by fermentation from adhering to the inner wall of the fermenter body 1.

[0057] At this time, sterile air is supplied to the inner cavity of the connecting pipe 2012 through the gas supply pipe 6. At the same time, the sterile air in the inner cavity of the connecting pipe 2012 can be discharged into the inner cavity of the gas supply trough 209 through the connecting cylinder 205. At this time, the sterile air in the inner cavity of the gas supply trough 209 can be discharged into the inner cavity of the fermenter body 1 through the exhaust port. During this process, the thrust generated by the nozzles 206 when discharging sterile air can cause the nozzles 206 to push the arc scraper 204 to move. At this time, the connecting cylinder 205 rotates in the opposite direction to the stirring rod 203 under the push of the multiple arc scrapers 204. At the same time, the multiple arc scrapers 204 scrape the bottom of the inner wall of the fermenter body 1. This can provide sufficient oxygen to the microorganisms while avoiding the precipitation of impurities during the fermentation process, thereby further improving the efficiency of mass and heat transfer of materials during the fermentation process, and effectively reducing the energy consumption required during the use of the fermenter body 1.

[0058] Meanwhile, under the drive of the connecting tube 205, the connecting tube 2012 drives the support ring 2010 to rotate along the outer wall of the limiting ring 7. At this time, multiple balls 2011 roll along the upper surface of the stirring rod 203 under the drive of the support ring 2010, thereby effectively reducing the friction between the support ring 2010 and the stirring rod 203.

[0059] When the material has completed fermentation, the electric valve is opened by an external controller, so that the fermented material can be transported to the subsequent device for further processing through the discharge pipe 5.

[0060] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
