Description

Technical Field

[0001] The invention belongs to the technical field of fermentation tanks, and in particular relates to a fermentation tank for fermenting Pleurotus eryngii strains. Background Art

[0002] King Oyster Mushroom, also known as Pleurotus eryngii, is named for its almond fragrance and thick abalone-like taste. It is a rare new edible variety that combines edible, medicinal and therapeutic uses. In the production process of King Oyster Mushroom, King Oyster Mushroom strains are needed to cultivate and reproduce King Oyster Mushroom strains. In order to facilitate the cultivation and reproduction of King Oyster Mushroom strains, fermentation tanks are needed to ferment the King Oyster Mushroom strains.

[0003] For example, a Chinese patent document (CN217509551U) discloses a temperature-controlled device for a Pleurotus eryngii spawn liquid fermentation tank, which belongs to the technical field of fermentation tanks. The key points of the technical solution include a fermentation tank body, a motor is fixedly installed on the upper end surface of the fermentation tank body, the output end of the motor passes through the upper end surface of the fermentation tank body and is fixedly installed with a stirring rod, and an insulation shell is fixedly installed on the outer wall of the fermentation tank body, so that the Pleurotus eryngii spawn liquid is added to the fermentation tank body for fermentation. When refrigeration is required, the second water pump guides the cooling water in the refrigeration box to the serpentine pipe through the connecting pipe, thereby refrigerating the fermentation tank body. The body is cooled down. When heating is needed, the water heated by the heating rod flows into the serpentine tube to heat the fermentation tank body. At the same time, the stirring rod rotates to stir the culture liquid, so that it is heated evenly and the fermentation of the culture liquid is accelerated, thereby achieving the effect of facilitating the adjustment of the temperature in the fermentation tank, so that the fermentation tank has the performance of constant temperature fermentation. However, during the use of the device, the existing stirring structure can only stir vertically, and the Pleurotus eryngii culture and raw materials cannot be fully mixed with the sterile air, resulting in low fermentation efficiency of the Pleurotus eryngii culture and raw materials during fermentation. Therefore, certain improvements are needed. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the existing stirring structure in the prior art can only perform vertical stirring during use, and the Pleurotus eryngii spawn and raw materials cannot be fully mixed with sterile air, resulting in low fermentation efficiency of the Pleurotus eryngii spawn and raw materials during fermentation. A fermentation tank for Pleurotus eryngii spawn fermentation is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A fermentation tank for fermenting Pleurotus eryngii spawn, comprising a tank body, a feed port and a motor are arranged on the top of the tank body, a rotating shaft is arranged at the bottom of the motor, a cavity is opened inside the rotating shaft, a mixing component is arranged inside the cavity, and an air supply component is arranged on the bottom side of the tank body; The mixing assembly includes a fixed rod, two first bevel gears are fixedly connected to the outer peripheral side of the top of the fixed rod, second bevel gears are meshed on both sides of the first bevel gears, and the two second bevel gears are fixedly connected to a connecting shaft on the separated side. One end of the connecting shaft extends to the outside of the rotating shaft and is fixedly connected to a transmission shaft, and first blades are symmetrically arranged on both sides of the transmission shaft.

[0006] Furthermore, a second blade is arranged directly below the first blade, and one side of the second blade is fixedly connected to the rotating shaft.

[0007] Furthermore, the air supply assembly includes two piston boxes, the bottom of which is fixedly connected to the bottom side of the tank body. Furthermore, a spring is fixedly connected to the top of the inner wall of the piston box, and the other end of the spring is fixedly connected to the piston.

[0008] Furthermore, the piston is slidably connected inside the piston box, and a plurality of one-way through holes are provided around the outer surface of the piston box.

[0009] Furthermore, an air guide pipe is provided on the bottom side of the tank body, one end of the air guide pipe extends to the outside of the tank body and is connected to an external inflation device, and the other end of the air guide pipe is connected to the bottom of the piston box.

[0010] Furthermore, the bottom end of the fixing rod is fixedly connected to the inner side of the bottom of the tank body, the fixing rod is arranged inside the rotating shaft, and the top end of the rotating shaft is rotatably connected to the top center of the tank body through a third bearing.

[0011] Furthermore, the two piston boxes are symmetrically arranged on both sides of the rotating shaft, and the one-way through holes are located within the length of both sides of the piston.

[0012] Furthermore, an observation window is provided on one side of the top of the tank body, and a discharge port is provided on one side of the bottom of the tank body.

[0013] Furthermore, the motor is arranged on the top side of the outside of the tank body, and the motor is fixedly connected to the outer wall of the tank body through a support base.

[0014] Compared with the prior art, the beneficial effects of this solution are as follows: 1. This solution sets a mixing component. After the Pleurotus eryngii spawn and the raw materials are put in, the motor drives the rotating shaft to rotate, and the rotating shaft drives the connecting shaft and the second blade thereon to stir horizontally. At the same time, under the action of the first bevel gear, the second bevel gear drives the connecting shaft and the second blade to rotate in a circle, and performs multi-angle composite stirring on the inside of the tank, so that the first blade and the second blade can act on different depths of the material at the same time, so that the sterile air is fully mixed with the Pleurotus eryngii spawn and the raw materials, thereby improving the fermentation efficiency of the Pleurotus eryngii spawn.

[0015] 2. This scheme sets an inflation component. After the Pleurotus eryngii spawn and raw materials are put into the tank body, the inflation device inputs sterile air into the piston box through the air guide hole. When the pressure exerted by the sterile air on the piston exceeds the reaction force of the spring on the piston, the piston rises along the inner wall of the piston box. When some of the one-way through holes are connected to the inside of the piston box, sterile air enters the tank body through the one-way through holes to generate bubbles. If it is necessary to further increase the concentration of sterile air in the Pleurotus eryngii spawn and raw materials, the inflation device is adjusted to increase its inflation rate, so that the pressure of the sterile air on the piston is further increased. The piston continues to move upward until all the one-way through holes are connected to the inside of the spring box, releasing more bubbles, thereby effectively improving the inflation efficiency of the inflation component.

DETAILED DESCRIPTION

[0018] The invention will be further described in detail below with reference to the accompanying drawings and through specific embodiments. The following embodiments are merely illustrative and are not intended to limit the scope of protection of the present invention. Example 1

[0019] A fermentation tank for fermenting Pleurotus eryngii strains, such as Figure 1-Figure 4 As shown, it comprises a tank body 1: a feed port 2 and a motor 3 are arranged on the top of the tank body 1, a rotating shaft 4 is arranged at the bottom of the motor 3, a cavity 8 is opened inside the rotating shaft 4, a mixing component 5 is arranged inside the cavity 8, and an air supply component 6 is arranged on the bottom side of the tank body 1; The mixing assembly 5 includes a fixed rod 501, and two first bevel gears 502 are fixedly connected to the outer peripheral side of the top of the fixed rod 501, and second bevel gears 503 are meshed on both sides of the first bevel gears 502. The two second bevel gears 503 are fixedly connected to a connecting shaft 507 on the separated side. One end of the connecting shaft 507 extends to the outside of the rotating shaft 4 and is fixedly connected to a transmission shaft 504. First blades 505 are symmetrically arranged on both sides of the transmission shaft 504.

[0020] In actual application, after the addition of the spawn and the raw materials, the motor 3 drives the rotating shaft 4 and the connecting shaft 507 to rotate. The synergistic effect between the connecting shaft 507 and the second blade 506 enables the second blade 506 to rotate horizontally around the center of the tank body 1. At the same time, the first bevel gear 502 and the second bevel gear 503 mesh with each other and rotate. This meshing mechanism causes the second bevel gear 503 to rotate vertically. Then the second bevel gear 503 drives the transmission shaft 504 to rotate, thereby driving the first blade 505 to rotate, so as to mix and ferment the Pleurotus eryngii spawn, raw materials and sterile air inside the tank body 1. Example 2

[0021] A fermentation tank for fermenting Pleurotus eryngii strains, which is different from Example 1 in that Figure 2 As shown, a second blade 506 is disposed directly below the first blade 505 , and one side of the second blade 506 is fixedly connected to the rotating shaft 4 .

[0022] In actual application, the first blade 505 rotates vertically while rotating horizontally, which enables the first blade 505 and the second blade 506 to fully stir the Pleurotus eryngii spawn, raw materials and sterile air at different depths, thereby improving the mixing efficiency of the spawn and raw materials during the fermentation process. Example 3

[0023] A fermentation tank for fermenting Pleurotus eryngii strains, which is different from Example 1 in that Figure 4As shown, the air supply assembly 6 includes two piston boxes 601, the bottom of the piston box 601 is fixedly connected to the bottom side of the tank body 1, the top of the inner wall of the piston box 601 is fixedly connected to a spring 603, the other end of the spring 603 is fixedly connected to a piston 602, the piston 602 is slidably connected to the inside of the piston box 601, and a plurality of one-way through holes 604 are opened around the outer surface of the piston box 601. An air guide pipe 7 is arranged on the bottom side of the tank body 1, one end of the air guide pipe 7 extends to the outside of the tank body 1 and is connected to an external inflation device, and the other end of the air guide pipe 7 It is connected to the bottom of the piston box 601, the bottom end of the fixing rod 501 is fixedly connected to the inner side of the bottom of the tank body 1, the fixing rod 501 is arranged inside the rotating shaft 4, and the top of the rotating shaft 4 is rotatably connected to the top center of the tank body 1 through the third bearing, the two piston boxes 601 are symmetrically arranged on both sides of the rotating shaft 4, the one-way through hole 604 is located on both sides of the piston 602, an observation window is opened on one side of the top of the tank body 1, and a discharge port is opened on one side of the bottom of the tank body 1, the motor 3 is arranged on the top side of the outside of the tank body 1, and the motor 3 is fixedly connected to the outer wall of the tank body 1 through a support seat.

[0024] In actual application, when in use, the Pleurotus eryngii spawn and raw materials are added to the tank body 1 through the feed port 2. After the addition is completed, the external inflation device injects sterile air into the piston box 601 through the air guide hole. When the pressure generated by the sterile air on the piston 602 exceeds the elastic force of the spring 603 on the piston 602, the piston 602 will rise along the inner wall of the piston box 601, gradually exposing part of the one-way through holes 604. At this time, sterile air enters the tank body 1 through these one-way through holes 604 to meet the amount of sterile air required during the fermentation process of the Pleurotus eryngii spawn. If it is necessary to increase the concentration of sterile air in the Pleurotus eryngii spawn and raw materials, the inflation rate of the inflation device is increased to further increase the pressure of the sterile air on the piston 602, and push the piston 602 to continue to slide upward until the one-way through hole 604 is completely exposed, so that it produces more bubbles, thereby effectively improving the inflation efficiency.

[0025] Working principle: When in use, add the Pleurotus eryngii strains and raw materials into the tank body 1 through the feed port 2. When the addition is completed, the inflation device inputs sterile air into the piston box 601 through the air guide pipe 7. When the pressure of the sterile air on the piston 602 is greater than the elastic force of the spring 603 on the piston 602, the piston 602 moves upward along the inner wall of the piston box 601, gradually exposing part of the one-way through hole 604. At this time, the gas will enter the tank body 1 through the one-way through hole 604 to provide the sterile air required for the fermentation process of the Pleurotus eryngii strains in the tank body 1. When it is necessary to increase the concentration of sterile air in the Pleurotus eryngii strains and raw materials, the inflation rate of the inflation device is increased. At this time, the pressure of the sterile air on the piston 602 is increased, so that the piston 602 continues to slide upward, gradually exposing all the one-way through holes 604, generating more bubbles, and improving the inflation efficiency; After the addition of the spawn and the raw materials is completed, the motor 3 is started, and the motor 3 drives the rotating shaft 4 and the connecting shaft 507 to rotate. The linkage effect between the connecting shaft 507 and the second blade 506 is used to transmit power to the second blade 506, so that the second blade 506 rotates horizontally with the center of the tank body 1, and the second bevel gear 503 meshes and rotates with the first bevel gear 502 to enable the second bevel gear 503 to achieve vertical rotation. The second bevel gear 503 drives the transmission shaft 504 to rotate, and the transmission shaft 504 drives the first blade 505 to rotate. The first blade 505 rotates vertically while rotating horizontally, so that the first blade 505 and the second blade 506 can fully mix the Pleurotus eryngii spawn and raw materials at different depths with the sterile air.
