A first liquid level sensor is fixedly connected to the upper part of the inner wall of the tank body, and a second liquid level sensor is fixedly connected to the lower part of the inner wall of the tank body.

[0008] In a preferred embodiment of the present invention, a mixing mechanism is further included.

The mixing mechanism includes a fixing frame, the fixing frame is fixedly connected to the inner wall of the sealing cover, a limiting frame is fixedly connected to the lower part of the fixing frame, a swinging hopper is rotatably connected to the fixing frame, two placing grooves are arranged on the swinging hopper, one of the placing grooves of the swinging hopper is located below the first feed pipe and the second feed pipe, one side of the lower part of the swinging hopper contacts the limiting frame, two guiding thin rods are fixedly connected to each of the two placing grooves of the swinging hopper, the two guiding thin rods in the same placing groove are a group, and a gravity plate is slidably connected between the two guiding thin rods in each group. Two pressing rods are slidably connected to the sealing cover, and a return spring is connected between the pressing rod and the sealing cover.

[0009] In a preferred embodiment of the present invention, a stirring mechanism is further included. The stirring mechanism is arranged on the sliding frame and is used for stirring the fermentation raw materials. The stirring mechanism includes a fixing table, the fixing table is fixedly connected to the middle of the sliding frame, a rotating ring is rotatably connected to the lower part of the fixing table, a driving gear is fixedly connected to the rotating ring, two long magnets are fixedly connected to the inner wall of the rotating ring, and the two long magnets are symmetrically distributed. Several magnet blocks are fixedly connected to the threaded rotating rod. Four bent round rods are fixedly connected to the lower part of the driving gear. Driven gears are rotatably connected to both sides of the sliding frame, and a groove column is fixedly connected to the rotating shaft of each driven gear.

[0010] The beneficial effects of the present invention are as follows: 1. The rotation of the threaded rotating rod drives the sieve net to rise or fall. The sinking of the sieve net can make the raw materials mix better, and the rising of the sieve net can facilitate the operator to clean out the raw material residues.

[0011] 2. The raw materials added from Feed Pipe 1 and Feed Pipe 2 will first accumulate in one of the placement slots of the swinging hopper, so that the solid-liquid raw materials can be preliminarily mixed. When the solid-liquid raw materials in one of the placement slots of the swinging hopper reach a certain amount, due to gravity, the swinging hopper will tilt and swing, and pour out the solid-liquid mixed raw materials in one of the placement slots. At this time, the other placement slot of the swinging hopper will be located below Feed Pipe 1 and Feed Pipe 2 and receive the solid-liquid raw materials. When the swinging hopper swings and tilts to both sides and pours out the solid-liquid raw materials, the gravity plate will move horizontally along the inner bottom surface of the swinging hopper, scraping off the wet tea leaves that may adhere to the placement slot of the swinging hopper. The swinging back and forth of the swinging hopper can continuously preliminarily mix the solid-liquid raw materials, so that the tea leaves in the solid raw materials can be wetted first, making it not easy to float on the liquid surface and affect fermentation.

[0012] 3. When a sufficient amount of liquid raw materials is added to the tank body, the threaded rotating rod rotates to drive the sliding frame to move downward. The rotation of the threaded rotating rod will drive the magnet block to rotate together. Since the magnet block and the long magnet have opposite magnetic poles and attract each other, the rotation of the threaded rotating rod will drive the rotating ring to rotate together through the magnet block and the long magnet. At the same time, the downward movement of the sliding frame will drive the fixed platform to move downward together, so that the rotating ring rotates with the threaded rotating rod while moving downward with the sliding frame. Then the rotation of the rotating ring will drive the driving gear to rotate together, and then drive the driven gear and the groove column to rotate. The rotation of the groove column will drive the dome rod and the floating disk to quickly float up and down through the wave groove. Then, while the two floating disks move downward with the sliding frame, the rapid up and down floating in the fermenting raw materials can cause the liquid level of the liquid fermenting raw materials to fluctuate violently, so that some of the solid raw materials floating on the surface can be fully wetted. At the same time, the rotation of the driving gear will drive the four curved round rods to rotate, which can stir the solid raw materials sinking on the screen, making the distribution of the solid raw materials more uniform, and thus making the fermentation more sufficient.

[0023] Embodiment 1

[0024] A fermentation device for processing tea wine, as Figure 1-8As shown in the figure, it includes three support feet 1. A tank body 2 is fixedly connected between the three support feet 1.

A sealing cover 42 is rotatably connected to the support ring 41. A connecting ring 43 is fixedly connected to the sealing cover 42. The connecting ring 43 is bolted to the support ring 41. A first feed hole and a second feed hole are respectively formed in the sealing cover 42. A first feed pipe 44 is fixedly connected to the first feed hole on the sealing cover 42. A second feed pipe 45 is fixedly connected to the second feed hole on the sealing cover 42. A discharge valve 46 is fixedly connected to the lower part of the tank body 2. The discharge valve 46 communicates with the inside of the tank body 2. A material fishing mechanism is arranged inside the tank body 2. The material fishing mechanism is used to fish out the fermentation raw materials. A lifting mechanism is arranged on the sealing cover 42. The lifting mechanism is used to lift or lower the material fishing mechanism.

[0025] The material fishing mechanism includes a cross frame 51. The cross frame 51 is fixedly connected to the lower part of the tank body 2. A threaded rotating rod 52 is rotatably connected to the middle of the cross frame 51. Two limiting rods 53 are fixedly connected to the inner wall of the tank body 2. The two limiting rods 53 are symmetrically arranged. A sliding frame 54 is threadedly connected to the threaded rotating rod 52. The sliding frame 54 is in contact with the two limiting rods 53 and the inner wall of the tank body 2. A screen 55 is fixedly connected to the sliding frame 54. The threaded rotating rod 52 passes through the screen 55.

[0026] The lifting mechanism includes a servo motor 61. The servo motor 61 is fixedly connected to the outer wall of the sealing cover 42. A rotating frame 62 is fixedly connected to the output shaft of the servo motor 61. The rotating frame 62 passes through the sealing cover 42. A transmission disk 63 is slidably connected to the lower part of the rotating frame 62. A number of protrusions are arranged on the lower part of the transmission disk 63. A return spring 64 is connected between the transmission disk 63 and the rotating frame 62. A clamping disk 65 is fixedly connected to the upper end of the threaded rotating rod 52. A number of grooves are formed in the clamping disk 65. The protrusions under the transmission disk 63 are located in the grooves on the clamping disk 65. A first liquid level sensor 66 is fixedly connected to the upper part of the inner wall of the tank body 2. A second liquid level sensor 67 is fixedly connected to the lower part of the inner wall of the tank body 2.

[0027] In actual work, tea wine needs to be brewed with raw materials such as tea leaves, water, sugar, and fermenting microorganisms. First, the operator needs to open the lids on the first feed pipe 44 and the second feed pipe 45, and then add the solid raw materials for brewing into the tank body 2 through the first feed pipe 44, and add the liquid raw materials for brewing into the tank body 2 through the second feed pipe 45. Initially, the solid raw materials added into the tank body 2 will fall on the screen 55. Then, when the liquid level of the liquid raw materials added into the tank body 2 reaches the position of the first liquid level sensor 66, the first liquid level sensor 66 is triggered. When the liquid level of the liquid in the tank body 2 reaches the position of the second liquid level sensor 67, the second liquid level sensor 67 is triggered. When both the second liquid level sensor 67 and the first liquid level sensor 66 are triggered, it will control the output shaft of the servo motor 61 to rotate. The rotation of the output shaft of the servo motor 61 will drive the rotating frame 62 and the transmission disc 63 to rotate together. Since the protrusion under the transmission disc 63 is located in the groove on the clamping disc 65, the rotation of the transmission disc 63 will drive the clamping disc 65 to rotate together. Then, the rotation of the clamping disc 65 will drive the threaded rotating rod 52 to rotate together. The rotation of the threaded rotating rod 52 will drive the sliding frame 54 to move downward through the thread. Then, the downward movement of the sliding frame 54 under the limitation of the limiting rod 53 will drive the screen 55 and the solid raw materials on it to move downward together, so that the solid raw materials are immersed in the liquid raw materials. Then, after the raw materials are mixed with each other, the lids on the first feed pipe 44 and the second feed pipe 45 are closed and the brewing starts. When the brewing is completed, the operator opens the discharge valve 46 again to export the brewed tea wine liquid. Due to the filtering effect of the screen 55, the raw material residues for brewing the tea wine will remain on the screen 55. Then, after all the liquid in the tank body 2 is exported through the discharge valve 46, and neither the first liquid level sensor 66 nor the second liquid level sensor 67 is triggered, it will control the output shaft of the servo motor 61 to rotate in the reverse direction. The reverse rotation of the output shaft of the servo motor 61 will finally drive the screen 55 to move upward to reset. The screen 55 drives the raw material residues to move upward. Then, the operator opens the sealing cover 42 again. The support frame 3 can support the opened sealing cover 42. Then, the operator clears the raw material residues on the screen 55. The sinking of the screen 55 can make the raw materials mix better, and the rising of the screen 55 can facilitate the operator to clean out the raw material residues.

[0028] Example 2

[0029] Based on Example 1, as Figure 4-6As shown, a mixing mechanism is also included, which is arranged on the inner wall of the sealing cover 42, and is used to mix fermentation raw materials. The mixing mechanism includes a fixed frame 71, and the fixed frame 71 is fixedly connected to the inner wall of the sealing cover 42. The lower part of the fixed frame 71 is fixedly connected to the limiting frame 72, and a swing bucket 73 is rotatably connected to the fixed frame 71. The swing bucket 73 is provided with two placement grooves, one of which is located below the feed pipe 1 44 and the feed pipe 2 45, and the lower part of one side of the swing bucket 73 contacts the limiting frame 72. Two guide thin rods 74 are fixedly connected in the two placement grooves of the swing bucket 73, and the two guide thin rods 74 in the same placement groove are a group, and a gravity plate 75 is slidably connected between the two guide thin rods 74 in each group, and two pressing rods 76 are slidably connected to the sealing cover 42, and a return spring 77 is connected between the pressing rod 76 and the sealing cover 42.

[0030] The operator adds solid raw materials through the feed pipe 1 44 and liquid raw materials through the feed pipe 2 45 respectively, and then the raw materials added from the feed pipe 1 44 and the feed pipe 2 45 will first be accumulated in one of the placement slots of the swing bucket 73, so that the solid and liquid raw materials can be preliminarily mixed. When the solid and liquid raw materials in one of the placement slots of the swing bucket 73 reach a certain amount, due to gravity, the swing bucket 73 will tilt and swing, and pour out the solid-liquid mixed raw materials in one of the placement slots. At this time, the other placement slot of the swing bucket 73 will be located below the feed pipe 1 44 and the feed pipe 2 45, and receive the solid and liquid raw materials. When the swing bucket 73 is respectively When the swing bucket 73 is swung and tilted to both sides and the solid and liquid raw materials are poured out, the gravity plate 75 will move horizontally along the inner bottom surface of the swing bucket 73, and scrape off the wet tea leaves that may be adhered to the placement groove of the swing bucket 73. The swing bucket 73 swings back and forth to continuously mix the solid and liquid raw materials preliminarily, so that the tea leaves in the solid raw materials can be soaked first, making it difficult for them to float on the liquid surface and affect fermentation. When the operator stops adding raw materials, he presses the two pressing rods 76 one after another, and the return spring 77 is compressed. The pressing rod 76 moves downward to squeeze the inner wall of the swing bucket 73, causing the swing bucket 73 to swing, so that the remaining solid and liquid raw materials in the swing bucket 73 can be poured out.

[0031] Example 3

[0032] On the basis of Example 2, Figure 7-8As shown, it further includes a stirring mechanism which is arranged on the sliding frame 54 and is used to stir the fermentation raw materials. The stirring mechanism includes a fixed platform 81 which is fixedly connected to the middle of the sliding frame 54. A rotating ring 82 is rotatably connected to the lower part of the fixed platform 81. A driving gear 83 is fixedly connected to the rotating ring 82. Two long magnets 84 are fixedly connected to the inner wall of the rotating ring 82 and are symmetrically distributed. A number of magnet blocks 85 are fixedly connected to the threaded rotating rod 52. Four curved round rods are fixedly connected to the lower part of the driving gear 83. Driven gears 87 are rotatably connected to both sides of the sliding frame 54. A groove column 88 is fixedly connected to the rotating shaft of each driven gear 87. A wave groove is formed on the outer wall of the groove column 88. Four limiting vertical rods 89 are fixedly connected to the sliding frame 54. Two limiting vertical rods 89 are in a group. A floating disc 810 is slidably connected between the two limiting vertical rods 89 in each group. A number of round top rods 811 are fixedly connected to each floating disc 810, and each round top rod 811 is located in the wave groove of the groove column 88.

[0033] At first, the magnet blocks 85 and the long magnets 84 have opposite magnetic polarities. After a sufficient amount of liquid raw materials are added into the tank body 2, the threaded rotating rod 52 rotates to drive the sliding frame 54 to move downward. The rotation of the threaded rotating rod 52 will drive the magnet blocks 85 to rotate together. Since the magnet blocks 85 and the long magnets 84 have opposite magnetic polarities and attract each other, the rotation of the threaded rotating rod 52 will drive the rotating ring 82 to rotate together through the magnet blocks 85 and the long magnets 84. At the same time, the downward movement of the sliding frame 54 will drive the fixed platform 81 to move downward together, so that the rotating ring 82 rotates with the threaded rotating rod 52 while moving downward with the sliding frame 54. Then the rotation of the rotating ring 82 will drive the driving gear 83 to rotate together, and further drive the driven gears 87 and the groove columns 88 to rotate together. The rotation of the groove column 88 will drive the round top rods 811 and the floating discs 810 to float up and down quickly through the wave grooves. Then, while the two floating discs 810 move downward with the sliding frame 54, the rapid up and down floating in the fermentation raw materials can cause the liquid level of the liquid fermentation raw materials to fluctuate violently, so that some solid raw materials floating on the surface can be fully wetted. At the same time, the rotation of the driving gear 83 will drive the four curved round rods 86 to rotate, which can stir the solid raw materials deposited on the screen 55, making the distribution of the solid raw materials more uniform, and thus making the fermentation more sufficient.
