Description

Technical Field

[0001] The invention relates to the field of liquid strain fermentation, in particular to a rapid fermentation tank for edible fungi liquid strains. Background Art

[0002] Liquid strains are edible fungi strains in liquid form produced by deep culture (liquid fermentation) technology in a biological fermentation tank using liquid culture medium. Liquid refers to the physical state of the culture medium, and liquid deep culture is a fermentation engineering technology. It is applied to the production of edible fungi. It is of great significance for the edible fungi industry to upgrade from traditional production that is cumbersome, complex, long-cycle, high-cost, based on experience, labor-intensive, and manual workshop-style to automation, standardization, and scale.

[0003] The liquid strain fermentation tank is a container for culturing microorganisms. A sterilized culture medium is added to the fermentation tank, and the culture medium is fully mixed with air by stirring or oscillating, so that the bacteria multiply in large quantities and produce carbon dioxide gas. The existing Chinese public patent document: CN217578867U discloses a rapid fermentation tank for edible fungi liquid strains. By setting an air supply pipe, a branch pipe, an inner pipe and a second spring, when oxygen needs to be transported to the fermentation tank, oxygen enters the surrounding branch pipes through the air supply pipe. The air pressure inside the branch pipe increases, which will push the inner pipe outward. During the outward movement of the inner pipe, the second spring will be squeezed through the retaining ring at one end. When one end of the inner pipe is pushed out of the branch pipe, the through hole on the surface of the branch pipe is opened, and oxygen will be discharged from the through hole. However, when oxygen is discharged from the exhaust hole, due to the buoyancy of the bubbles, it will be quickly discharged upward from the exhaust port, so that the oxygen cannot reach the edge of the inner side of the fermentation tank, resulting in uneven oxygen injection, which will reduce the fermentation speed of the liquid strain.

[0024] The heating mechanism includes a heating motor 24 fixedly mounted on the top of the mounting frame 17. The heating motor 24 is located directly above the rotating drum 14. An electric heating rod 25 extending to the inner side of the rotating drum 14 is fixedly mounted at the bottom of the heating motor 24. A heat-conducting pipe 26 is slidably sleeved on the outer side of the electric heating rod 25. The heating motor 24 can heat the heat-conducting pipe 26 through the electric heating rod 25. The outer side of the heat-conducting pipe 26 contacts the inner side of the rotating drum 14. A spiral heat-conducting coil 27 is arranged on the inner side of the spiral strip 21. A cavity for installing the spiral heat-conducting coil 27 is opened on the inner side of the spiral strip 21. Both ends of the spiral heat-conducting coil 27 are fixedly connected to the outer side of the heat-conducting pipe 26, so that the heat-conducting pipe 26 can conduct the temperature to the spiral heat-conducting coil 27. The rotating drum 14 and the spiral strip 21 are both made of heat-conducting materials, which is convenient for conducting the temperature on the heat-conducting pipe 26 and the spiral heat-conducting coil 27 to the liquid bacteria in the tank body 1, so as to comprehensively heat the liquid bacteria. When the heating motor 24 is running, the heat pipe 26 can be heated by the electric heating rod 25, and the heat can be transferred to the drum 14 and the spiral heat-conducting coil 27. The drum 14 can transfer the heat to the liquid bacteria in the middle position of the tank body 1. The spiral heat-conducting coil 27 heats the spiral strip 21, so that the spiral strip 21 transfers the heat to the liquid bacteria on the inner side of the tank body 1, thereby achieving rapid heating of the liquid bacteria, thereby increasing the fermentation speed of the liquid bacteria.

[0025] Working principle: First, the user opens the liquid inlet pipe 2 and injects the liquid bacteria and fermentation agents into the tank body 1. Then, the user starts the compressed air pump 7, so that the compressed air pump 7 inputs oxygen into the gas collecting cylinder 8 through the gas pipe 10. The oxygen enters the exhaust pipe 11 through the one-way valve 12 and is discharged from the nozzle 13 on the exhaust pipe 11, injecting oxygen into the bottom of the liquid bacteria in the tank body 1. At this time, the user starts the driving motor 18 and the heating motor 24. The driving motor 18 drives the rotating drum 14 to rotate synchronously through the synchronous belt 19, so that the rotating drum 14 drives the stirring rod 23 and the spiral strip 21 to rotate synchronously. The stirring rod 23 stirs the liquid bacteria located outside the rotating drum 14, and the spiral strip 21 stirs the liquid bacteria near the inner wall of the tank body 1 through the stirring bar 22. At the same time, the rotating drum 14 drives the docking socket 16 to rotate through the prismatic plug 15, so that the docking socket 16 drives the gas collecting cylinder 8 to rotate. The gas collecting cylinder 8 drives the four exhaust pipes 11 to rotate, so that oxygen can be evenly injected into the liquid bacteria. The rotation of the exhaust pipes 11 can be used to stir the bottom of the liquid bacteria to prevent the bottom of the liquid bacteria from sinking. As a result, the liquid bacteria are fully mixed with the fermentation agent and oxygen. At the same time, the heating motor 24 heats the heat-conducting pipe 26 through the electric heating rod 25, and transfers the heat to the rotating drum 14 and the spiral heat-conducting coil 27. The rotating drum 14 heats the liquid bacteria in the middle position of the tank body 1. At the same time, the spiral heat-conducting coil 27 heats the spiral strip 21, so that the spiral strip 21 heats the liquid bacteria at the inner side of the tank body 1, thereby realizing rapid heating of the liquid bacteria and promoting the fermentation of the liquid bacteria. Finally, the user opens the drain valve 3 to discharge the liquid bacteria in the tank body 1, thereby achieving the effect of uniform oxygen injection and rapid fermentation, and improving the fermentation efficiency of the liquid bacteria.

[0026] Example 2: Please refer to Figure 2-Figure 5 The present embodiment further explains Example 1. A positioning shaft 29 is fixedly installed on one end of the gas collecting cylinder 8 near the positioning cylinder 9 in the figure. An annular groove is provided on the inner side of the positioning cylinder 9 for the limited sliding of the positioning shaft 29, thereby improving the smoothness of the rotation of the gas collecting cylinder 8. The inner side of the gas collecting cylinder 8 is a rounded structure to provide a guide for the circulation of oxygen. The stirring rods 23 on both sides of the rotating drum 14 are distributed in a stepped manner to improve the comprehensiveness of the stirring of the stirring rods 23. A scraper 30 is fixedly installed on the side of the stirring bar 22 away from the spiral bar 21. The side of the scraper 30 away from the stirring bar 22 is in contact with the inner side of the tank body 1, so as to scrape out the liquid bacteria adhering to the inner side of the tank body 1 and facilitate mixing.

[0027] In this embodiment: when the drum 14 rotates, the scraper 30 on the stirring bar 22 can be driven by the spiral bar 21 to move along the inner side of the tank body 1, so as to scrape out the liquid bacteria sticking to the inner side of the tank body 1 and mix it with the fermentation agent. When the tank body 1 is cleaned, the scraper 30 can be used to clean the liquid bacteria remaining on the inner side of the tank body 1, so as to improve the convenience during mixing and cleaning. When oxygen enters the gas collecting cylinder 8, the rounded corners on the inner side of the gas collecting cylinder 8 facilitate the pouring of oxygen into the exhaust pipe 11, so as to facilitate the circulation of oxygen. When the stirring rod 23 on the outer side of the drum 14 rotates, the stepped distribution of the stirring rod 23 can improve the stirring efficiency of the liquid bacteria outside the drum 14, and there is no need to add too many stirring rods 23, so as to facilitate the later cleaning. The gas collecting cylinder 8 can move smoothly in the positioning cylinder 9 through the positioning shaft 29, so as to ensure the smooth rotation of the exhaust pipe 11.

[0028] Example 3: Please refer to Figure 1 and Figure 6 This embodiment further illustrates other embodiments. An elastic bracket 28 is fixedly installed at the bottom of the tank body 1 in the figure to provide shock absorption for the tank body 1. A temperature monitoring panel 31 is fixedly installed on the outer side of the heating motor 24 to adjust the temperature of the heating motor 24.

[0029] In this embodiment: when the liquid bacteria in the tank body 1 are stirred and mixed, the elastic bracket 28 can provide a buffering and shock-absorbing effect for the tank body 1 to ensure the stability of the tank body 1. The temperature monitoring panel 31 on the outside of the heating motor 24 can monitor the temperature of the heating motor 24 in real time, which is convenient for adjusting the temperature of the electric heating rod 25 to ensure the normal fermentation of the liquid bacteria.
