Description

Technical Field

[0001] The invention belongs to the technical field of bacterial strain fermentation, and in particular relates to a Pleurotus eryngii liquid bacterial strain fermentation system. Background Art

[0002] Pleurotus eryngii is an edible fungus that can be used as both medicine and food. The liquid strain is an edible fungus strain in liquid form produced by deep culture technology in a biological fermentation tank using liquid culture medium.

[0003] CN115747005A is retrieved and disclosed as a Pleurotus eryngii liquid spawn fermentation system, comprising a fermentation tank, an air filter device, and a liquid conveying device, wherein the fermentation tank is fixedly connected to the liquid conveying device, and the liquid conveying device is fixedly connected to the air filter device. The present invention injects water into the water injection pipe, and since the inner diameter of the water injection pipe is smaller than the inner diameter of the second fixed pipe, the second fixed pipe gradually moves downward under the impact of water pressure, and due to the impact of the water flow on the fan blade, the fan blade can drive the second fixed pipe to rotate through the first sleeve and the second connecting assembly, and when the water flow enters the interior of the limit assembly through the connecting pipe, it can impact the impeller, thereby driving the cleaning assembly to move up and down as a whole by driving the fixed plate, and the water flow can be discharged through the drainage hole to wash the inner wall, thereby achieving the cleaning effect on the inner wall of the fermentation tank body.

[0004] However, the inventors have discovered that this technical solution still has at least the following defects:

[0005] In the actual fermentation operation process, stirring the fermentation liquid only by the second fixed tube at a fixed position can easily lead to insufficient stirring, and the second fixed tube is driven to rotate by water flow, and the second fixed tube is placed inside the fermentation liquid, so the rotation of the second fixed tube has resistance, and the water flow cannot drive the second fixed tube to rotate well, affecting the stirring effect.

[0053] Embodiment 3:

[0054] The difference between the above embodiment and this embodiment is that: Figure 3 , Figure 5 and Figure 6As shown, slide plates 304 are installed on both sides of the limit slider 3031, and a plug rod 3041 is installed on the slide plate 304, and a limit plate 3043 is installed on one side of the plug rod 3041, and a mounting seat 3044 is welded on the other side of the plug rod 3041, and the mounting seat 3044 is installed on the inner wall of the end cover 102, and a return spring 3042 is sleeved on the plug rod 3041, and one side of the return spring 3042 is clamped on the mounting seat 3044, and the other side of the return spring 3042 is clamped on the slide plate 304.

[0055] like Figure 8 As shown, in a specific embodiment, four pairs of vertical plates 3061 are installed on the ring 306, and a sliding rod 3062 is installed on each pair of vertical plates 3061.

During the movement of the limit slider 3031, the back plate 4012 on the limit slider 3031 drives the top block 401 to move back and forth.

[0057] The implementation principle of the Pleurotus eryngii liquid spawn fermentation system of this embodiment is as follows:

[0058] When the device needs to be used, the operator needs to open the sealing cover 1041 and pour a certain amount of bacterial liquid and bacterial strains into the feed hopper 104. The input content can be displayed in real time through the observation window frame 103 and the scale line 1031 on the side wall of the fermentation tank 101. After a certain content is input, the sealing cover 1041 needs to be resealed to ensure the fermentation environment.

[0059] Next, the stirring motor 201 needs to be started, and the driving shaft 2011 is driven to rotate by the stirring motor 201. The driving shaft 2011 is equipped with a rotating shaft 202, and the rotating shaft 202 can drive the installation shaft 2021 and the stirring shaft 203 to rotate. The stirring shaft 203 is equipped with a stirring plate 2032 through a clamping plate 2031. The rotation of the stirring plate 2032 can fully stir the bacterial liquid inside the fermentation tank 101, ensuring that the bacterial species in the bacterial liquid can be evenly distributed to various positions.

[0060] During the rotation of the mounting shaft 2021, the mounting bracket 204 at the bottom can drive the scraper 2041 to rotate, and the scraper 2041 can move on the inner wall of the fermentation tank 101. When cleaning is needed later, the scraper 2041 can clean the bacteria attached to the inner wall, thereby improving the cleaning effect.

[0061] During the rotation of the transmission shaft 2011, the driving bevel gear 3013 on the transmission shaft 2011 drives the driven bevel gear 3012 to rotate, and the driven bevel gear 3012 can drive the adjusting roller 301 to rotate through the positioning shaft 3011, and the adjusting roller 301 is provided with a cylindrical cam groove 302, and a guide block 3021 is slidably provided on the cylindrical cam groove 302, and the guide block 3021 is provided with a limit slider 3031 which can drive the limit slider 3032 to slide in the limit slider groove 3032 to perform a limit operation, so the rotation of the adjusting roller 301 can drive the limit slider 3031 to reciprocate along the limit slider groove 3032.

[0062] During the reciprocating motion of the limit slider 3031, the slide plate 304 on the limit slider 3031 moves along the insertion rod 3041, and the limit plate 3043 and the mounting seat 3044 are installed on the insertion rod 3041 to ensure that the slide plate 304 will not be separated from the insertion rod 3041, and during the movement, the slide plate 304 can compress the return spring 3042, and the return spring 3042 facilitates the subsequent return operation.

[0063] When the limit slider 3031 moves outward along the limit slide groove 3032, the connection seat 3051 drives one end of the swing rod 305 to move outward, and the other end of the swing rod 305 is sleeved with a slide bar 3062, and the slide bar 3062 is installed on the collar 306, so that the collar 306 can pull the stirring shaft 203 at the bottom to move upward, and the stirring position of the stirring plate 2032 on the stirring shaft 203 changes, so that the bacterial liquid of different depths can be stirred, and the mixing effect is improved. When the stirring shaft 203 rotates, the stirring shaft 203 and the collar 306 are slidably connected to ensure that the stirring shaft 203 can move up and down during the process of controlling the rotation of the stirring shaft 203. In addition, when the swing rod 305 swings on the slide bar 3062, the torsion spring 3063 is twisted, and the torsion spring 3063 is used to facilitate the reset process later.

[0064] During the movement of the limit slider 3031, the back plate 4012 on the limit slider 3031 drives the top block 401 to move back and forth. When the ventilation groove 4011 on the top block 401 moves to the ventilation port 402, the gas generated by the internal fermentation of the fermentation tank 101 can move to the outside through the ventilation groove 4011, thereby achieving the purpose of discharging carbon dioxide and injecting fresh air into the interior, thereby ensuring the subsequent fermentation of the bacteria.
