Description

Technical Field

[0001] This utility model relates to the field of food processing, specifically a lactic acid bacteria fermentation device. Background Technology

[0002] Lactic acid bacteria are a collective term for a class of bacteria that can utilize fermentable carbohydrates to produce large amounts of lactic acid. These bacteria are widely distributed in nature and have rich species diversity. Most of them are essential bacteria in the human body and have important physiological functions. When processing lactic acid bacteria, a fermentation chamber is usually required. Lactic acid bacteria fermentation chambers usually have a precise temperature control system to maintain a constant growth temperature, which is crucial for the activity of lactic acid bacteria and the fermentation effect.

[0003] Chinese utility model patent CN211005361U discloses a lactic acid bacteria fermentation incubator with uniform heating. By pressing down on the support rod, the fixing plate installed on the lower side of the fixing rod fits tightly with the connecting block with a semi-circular cross-section, and pushes the connecting block to slide outward on the middle handle. The connecting plate slides and connects with the side handle slot, which can adjust the opening area of ​​the incubator door as needed. It is easy to operate, has a stable structure, and is highly flexible.

[0004] When the plate containing the petri dishes is placed inside the fermentation chamber, the patent describes a process where several plates are typically placed vertically inside the fermentation chamber. The space between adjacent plates is limited. Due to the lack of a mechanism to increase the operating space above the plates, workers need to pull the entire plate out of the fermentation chamber to retrieve the petri dishes located behind the plates. Based on this, we propose a lactic acid bacteria fermentation device. Utility Model Content

[0005] The purpose of this invention is to provide a lactic acid bacteria fermentation device to solve the problem mentioned in the background art, which is that the lack of a mechanism to increase the operating space above the placement plate makes it difficult for workers to access the culture dishes located behind the placement plate.

[0006] The technical solution of this utility model is: a lactic acid bacteria fermentation device, comprising several sets of concave blocks, a placement plate, an adjustment mechanism, and a moving mechanism arranged inside a fermentation chamber. Two concave blocks in each set are fixedly connected to both sides of the inner wall of the fermentation chamber. A placement plate is slidably arranged between each set of concave blocks. The adjustment mechanism is arranged at the bottom of the placement plate. A connecting plate is slidably arranged on the adjustment mechanism. A concave seat is fixedly connected to the bottom of the connecting plate. A rotating plate is rotatably connected to the bottom of the concave seat. A support rod is fixedly connected to one side of the rotating plate. The moving mechanism is arranged at the bottom of the concave block. A guide hole is opened at the bottom of the concave block. A support spring is arranged inside the guide hole. A limiting block is fixedly connected to one side of the support spring. A stop rod is fixedly connected to the bottom of the limiting block. The outer wall of the support rod contacts the outer wall of the stop rod.

[0007] Preferably, each set of concave blocks has a threaded cylinder fixedly connected to its top, a screw is connected inside the threaded cylinder, a connecting rope is fixedly connected to the top of the screw, and one end of the two connecting ropes is fixedly connected to the top of the same placement plate.

[0008] Preferably, the adjusting mechanism includes a contraction spring, a set of rotating rods are rotatably connected to both sides of the placement plate, a pulley is fixedly connected to one end of each rotating rod, two sliding grooves are opened at the bottom of the placement plate, the two sliding grooves are symmetrically arranged, a fixed rod is fixedly connected inside each of the two sliding grooves, a slider is slidably connected to the outer wall of the fixed rod, the top of the connecting plate is fixedly connected to the bottom of the two sliders, two contraction springs are fixedly connected to the bottom of the connecting plate, the two contraction springs are symmetrically arranged, and the top of the rotating plate is fixedly connected to the bottom of the two contraction springs.

[0009] Preferably, it also includes a T-shaped sliding plate, wherein a T-shaped groove is provided on one side of the inner wall of the placement plate, and a plurality of T-shaped sliding plates are slidably connected inside the T-shaped groove.

[0010] Preferably, the moving mechanism includes a storage groove, a storage groove is provided on one side of the guide hole and a positioning groove is provided on the other side, one end of the support spring is fixedly connected to one side of the storage groove, the outer wall of the limiting block is slidably connected to the inside of the storage groove, and a limiting hole communicating with the inside of the storage groove is provided at the bottom end of the concave block.

[0011] Preferably, the concave blocks in each group are arranged in a linear array at equal intervals along one side of the inner wall of the fermentation tank, and the two concave blocks in each group are arranged symmetrically.

[0012] This utility model provides an improved lactic acid bacteria fermentation device, which has the following improvements and advantages compared with the prior art:

[0013] 1. This utility model pulls the rotating plate downwards onto the placement plate, causing the rotating plate to completely displace the support rod and the stop rod. This limiting block supports the pulley, allowing the staff to directly slide the placement plate into a set of concave blocks for placement. When the retraction spring retracts the rotating plate, the outer wall of the support rod contacts the outer wall of the stop rod, and the support rod can drive the stop rod to move, causing the stop rod to completely retract the limiting block into the storage groove. This releases the support on the pulley on the front side of the placement plate, allowing the front side of the placement plate to rotate downwards, thereby increasing the operating space at the top of the placement plate. This makes it easier for the staff to retrieve the culture dish located on the back side of the placement plate. The rotation angle of the placement plate can be limited by the connecting rope.

[0021] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0022] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0023] A lactic acid bacteria fermentation device includes several sets of concave blocks 2, a placement plate 3, an adjustment mechanism, and a moving mechanism disposed inside a fermentation chamber 1. Two concave blocks 2 in each set are fixedly connected to the two sides of the inner wall of the fermentation chamber 1. A placement plate 3 is slidably disposed between each set of concave blocks 2. An adjustment mechanism is disposed at the bottom of the placement plate 3. A connecting plate 9 is slidably disposed on the adjustment mechanism. A concave seat 10 is fixedly connected to the bottom of the connecting plate 9. A rotating plate 11 is rotatably connected to the bottom of the concave seat 10. A support rod 13 is fixedly connected to one side of the rotating plate 11. A moving mechanism is disposed at the bottom of the concave blocks 2. A guide hole 24 is opened at the bottom of the concave blocks 2. A support spring 15 is disposed inside the guide hole 24. A limiting block 16 is fixedly connected to one side of the support spring 15. A stop rod 17 is fixedly connected to the bottom of the limiting block 16. The outer wall of the support rod 13 contacts the outer wall of the stop rod 17.

[0024] With the coordination of the adjustment mechanism and the moving mechanism, when the support rod 13 is below the stop rod 17, it is convenient to place the placement plate 3 between a set of concave blocks 2. When the outer wall of the support rod 13 contacts the outer wall of the stop rod 17, the support rod 13 can drive the stop rod 17 to move, so that the stop rod 17 can drive the limiting block 16 to move, thereby releasing the restriction on the front side of the placement plate 3, making it convenient for the front side of the placement plate 3 to rotate downward, thereby increasing the operating space at the top of the placement plate 3, making it easier for staff to pick up the culture dish located on the back side of the placement plate 3.

[0025] Furthermore, each set of concave blocks 2 is fixedly connected to the top of a threaded cylinder 21, and a screw 22 is connected inside the threaded cylinder 21. A connecting rope 23 is fixedly connected to the top of the screw 22. One end of the two connecting ropes 23 is fixedly connected to the top of the same placement plate 3. Due to the limitation of the length of the connecting rope 23, the rotation angle of the placement plate 3 can be limited, so as to avoid the placement plate 3 located above from colliding with the placement plate 3 located below when rotating downward.

[0026] Furthermore, the adjustment mechanism includes a contraction spring 12, a set of rotating rods 4 are rotatably connected to both sides of the placement plate 3, a pulley 5 is fixedly connected to one end of the rotating rod 4, two sliding grooves 6 are opened at the bottom of the placement plate 3, the two sliding grooves 6 are symmetrically arranged, a fixed rod 7 is fixedly connected inside each of the two sliding grooves 6, a slider 8 is slidably connected to the outer wall of the fixed rod 7, the top of the connecting plate 9 is fixedly connected to the bottom of the two sliders 8, and two contraction springs 12 are fixedly connected to the bottom of the connecting plate 9, the two contraction springs 12 are symmetrically arranged, the top of the rotating plate 11 is fixedly connected to the bottom of the two contraction springs 12, and the force of the two contraction springs 12 facilitates the contraction of the rotating plate 11, so that the outer wall of the supporting rod 13 contacts the outer wall of a set of stop rods 17, which facilitates the subsequent movement of the stop rods 17 by the supporting rod 13.

[0027] Furthermore, it also includes T-shaped slide plates 20. A T-shaped groove 19 is provided on one side of the inner wall of the placement plate 3. Several T-shaped slide plates 20 are slidably connected inside the T-shaped groove 19, which makes it easy to adjust the spacing between adjacent T-shaped slide plates 20 according to the specifications of the petri dish.

[0028] Furthermore, the moving mechanism includes a storage groove 14, a storage groove 14 is provided on one side of the guide hole 24, and a positioning groove 25 is provided on the other side. One end of the support spring 15 is fixedly connected to one side of the storage groove 14. The outer wall of the limiting block 16 is slidably connected to the inside of the storage groove 14. The bottom end of the concave block 2 is provided with a limiting hole 18 that communicates with the inside of the storage groove 14, so that the force of the support spring 15 can be used to drive one end of the limiting block 16 to be embedded in the positioning groove 25, thereby supporting the position of the limiting block 16.

[0029] Furthermore, each set of concave blocks 2 is arranged in a linear array at equal intervals along one side of the inner wall of the fermentation tank 1, and the two concave blocks 2 in each set are arranged symmetrically, so that the two sets of pulleys 5 on the outside of the placement plate 3 can be slid into the two concave blocks 2 respectively, thereby placing and supporting the placement plate 3.

[0030] Working principle: First, pull the rotating plate 11 downwards on the placement plate 3, causing the rotating plate 11 to rotate at the bottom of the concave seat 10. This causes the rotating plate 11 to stretch the two contraction springs 12, which in turn causes the rotating plate 11 to rotate the support rod 13 downwards on the placement plate 3. At this time, the support rod 13 is located below a set of stop bars 17. Due to the action of the support spring 15, the support spring 15 causes one end of the limiting block 16 to be embedded in the positioning groove 25. This facilitates the placement plate 3 driving the two sets of pulleys 5 to slide into the concave block 2. The two pulleys 5 located on the front side of the placement plate 3 are respectively located in two... The surface of the limiting block 16 is used to support the placement plate 3. Pull the screw 22 so that the screw 22 is screwed into the threaded cylinder 21. At this time, the rotating plate 11 is released. Due to the force of the contraction spring 12, the rotating plate 11 is driven to reset. The outer wall of the support rod 13 contacts the outer wall of a set of stop rods 17. Then, pull several T-shaped slide plates 20 so that several T-shaped slide plates 20 slide inside the T-shaped groove 19. This makes it easy to adjust the spacing between adjacent T-shaped slide plates 20 according to the size of the petri dish. Then, start the fermentation box 1 to facilitate the fermentation of the material inside the petri dish on the placement plate 3.

[0031] Next, when the staff member takes the petri dish, the staff member presses the front side of the placement plate 3 with their thumb, and holds and pulls the support rod 13 towards the front of the fermentation box 1 with the other four fingers. This causes the support rod 13 to move the connecting plate 9, which in turn causes the connecting plate 9 to move the slider 8 on the fixed rod 7. This causes the support rod 13 to move the stop rod 17, which causes one end of the limiting block 16 to separate from the positioning groove 25 and be completely stored in the storage groove 14. The stop rod 17 moves along the inside of the limiting hole 18, thereby releasing the support of the pulley 5 on the front side of the placement plate 3. With the support of the two pulleys 5 on the rear side of the placement plate 3 and the rotation of the two rotating rods 4, the front side of the placement plate 3 rotates downward, thereby increasing the operating space at the top of the placement plate 3 and making it easier for the staff member to take the petri dish located on the rear side of the placement plate 3. At this time, due to the limitation of the length of the connecting rope 23, the rotation angle of the placement plate 3 can be limited to avoid the placement plate 3 located above from colliding with the placement plate 3 located below when rotating downward.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
