Description

Technical Field

[0001] This utility model relates to the field of fungal grinding technology, specifically to a grinding device for homogenizing Lactobacillus production. Background Technology

[0002] Grinding is a pretreatment step in the Lactobacillus homogenization process. Its core function is to solve the problem of unevenness in the bacterial sludge, preparing it for subsequent high-pressure homogenization. Specific purposes include: avoiding homogenization dead zones and ensuring homogenization effect: if bacterial sludge containing large bacterial aggregates is directly subjected to high-pressure homogenization, the bacteria inside the aggregates are difficult to contact the shearing and impact forces of the homogenizer, resulting in some bacteria not being fully processed and uneven bacterial dispersion in the final product; grinding refines the aggregates into small particles, allowing all bacteria to receive homogenization evenly; protecting homogenization equipment and reducing energy consumption: when large bacterial aggregates or hard impurities enter the high-pressure homogenizer, they may wear down the homogenization valve and increase the equipment load. Grinding can remove or refine these substances in advance, extending the equipment life and reducing energy consumption.

[0003] However, the mixture of lactobacillus after fermentation contains a large amount of water. This water not only affects the production quality but also increases the amount of grinding required. Therefore, it is necessary to process the mixture in advance by filtration to collect the bacterial sludge. The collected bacterial sludge is then fed into the grinding device. This step-by-step operation requires more time to process, which not only reduces the processing efficiency but also requires manual operation at each step, increasing the amount of manual labor.

[0030] like Figures 1 to 5 As shown, this utility model provides a grinding device for homogenizing Lactobacillus, characterized in that it includes a body 1, a centrifugal filtration component, an intermediate connecting component, and a grinding component;

[0031] The centrifugal filtration component and the grinding component are installed in the machine body respectively, with the centrifugal filtration component located above the grinding component;

[0032] The discharge end of the centrifugal filtration component is connected to the feed end of the grinding component through an intermediate connecting component.

[0033] Specifically, in combination Figure 2 Internal structure and Figure 3 The cross-sectional diagram shows that the centrifugal filter assembly includes an outer cylinder 21, an inner cylinder 22, and a first motor 23. The outer cylinder 21 is fixed inside the machine body 1 by a fixing bracket 211. The inner cylinder 22 is provided inside the outer cylinder 21, and the upper ends of both the outer cylinder 21 and the inner cylinder 22 are open. The top of the outer cylinder 21 is in contact with the inner wall of the machine body 1, and a sealing ring 212 is provided at the contact position between the outer cylinder 21 and the machine body 1. The sealing ring 212 increases the sealing performance at the contact position between the outer cylinder 21 and the machine body 1, preventing the mixture from entering the cavity of the machine body 1 and causing moisture inside the machine body 1, which would affect the internal equipment.

[0034] A rotating shaft 231 is fixed on the bottom wall of the inner cylinder 22. The upper end of the rotating shaft 231 passes through the machine body and is connected to the output end of the first motor 23. The rotation of the inner cylinder 22 is controlled by the first motor 23. Filter holes are arranged at intervals on the side wall of the inner cylinder 22 to complete the centrifugal dehydration operation of the mixture.

[0035] Depend on Figure 4From a top-down view of point A, it can be seen that the discharge port 221 is arranged in a ring around the bottom of the inner cylinder 22, and the discharge port 221 is located at the lowest point inside the inner cylinder 22, and is arranged around the outside of the connection between the rotating shaft 231 and the inner cylinder 22.

[0036] The first motor 23 is mounted on the top of the machine body 1 via a motor mount. The top of the machine body 1 is provided with a feeding port, which is connected to the inner cylinder 22. The mixture of lactobacillus fermented to be processed is fed from the feeding port 12 of the machine body 1. The material enters the inner cylinder 22 inside the machine body 1. A drain outlet is provided at the bottom of the outer cylinder 21, and a drain pipe 213 is installed at the drain outlet. The filtered water is discharged through the drain pipe 213.

[0037] Combination Figure 2 Internal structure and Figure 3 and Figure 5 The cross-sectional diagram shows that the grinding assembly includes a grinding box 31, grinding rollers 32, and a drive unit. The grinding box 31 is fixed on a support frame 311, which is connected and fixed to the bottom of the machine body 1 by bolts. Two sets of grinding rollers 32 are installed inside the grinding box 31 through bearings. Both sets of grinding rollers 32 are connected to the drive unit. Both sets of grinding rollers 32 are provided with grinding teeth 321, and the grinding teeth 321 on each of the two sets of grinding rollers 32 are arranged in a staggered manner. The grinding operation of the material is completed by the staggered movement of the grinding teeth 321.

[0038] The drive unit includes a second motor 331, a drive wheel 332, and a driven wheel 333. The output end of the second motor is connected to the drive wheel 332, and the drive wheel 332 meshes with the driven wheel 333. The drive wheel 332 and the driven wheel 333 are respectively fixedly mounted on the central shaft of the grinding roller 32. When the second motor 331 drives the drive wheel 332 to rotate, the meshing transmission between the drive wheel 332 and the driven wheel 333 causes the driven wheel 333 to rotate, thus realizing the opposite rotation of the two sets of grinding rollers and completing the grinding operation of the material.

[0039] The intermediate connecting assembly includes a transition pipe 41 and a conveying pipe 42. The feed end of the transition pipe 41 is fixedly connected to the bottom of the inner cylinder 22. The discharge port 221 of the inner cylinder 22 is connected to the feed end of the transition pipe 41. The transition pipe 41 is used to collect the bacterial sludge in the inner cylinder 22. The transition pipe 41 passes through the outer cylinder 21 and extends out. A bearing and a sealing ring are provided at the connection between the transition pipe 41 and the outer cylinder 21. The discharge end of the transition pipe 41 is connected to the conveying pipe 42 through a rotary joint. This rotary joint is a commercially available device. Its rotating end is connected to the transition pipe 41 and its stationary end is connected to the conveying pipe 42. It is a transitional connection between dynamic and static pipes. Therefore, its specific structure will not be described in detail in this application.

[0040] In addition, control valves are installed on the conveying pipe 42, drain pipe 213, and discharge pipe 312. These control valves are electrically connected to the control panel 11 fixed on the machine body 1. The control valves control the opening and closing of the pipes. Since the control valves are commercially available equipment, their specific structure will not be described in detail in this application. The first motor 23 and the second motor 331 are also electrically connected to the control panel 11, which controls the start and stop of the first motor 23 and the second motor 331.

[0041] The working principle and process of this utility model are as follows:

[0042] Feeding operation: During the grinding process, the control valves on the conveying pipe 42 and the drain pipe 213 are closed. The production line operator only needs to feed the mixture to be processed from the feeding port 12 on the machine body 1 so that the material enters the inner cylinder 22 of the centrifugal filter assembly.

[0043] Centrifugal filtration: Start the first motor 23, which controls the inner cylinder 22 to rotate, thus completing the centrifugal filtration of the mixture. The filtered water enters between the inner cylinder 22 and the outer cylinder 21 through the filter holes on the side wall of the inner cylinder 22, while the separated bacterial mud remains in the inner cylinder 22.

[0044] Material conveying: Open the control valves on the conveying pipe 42 and the drain pipe 213 to allow the filtered water to be discharged, and the separated bacterial mud enters the grinding box 31 from the conveying pipe 42;

[0045] Grinding process: Start the second motor 331, and through the meshing transmission of the drive wheel 332 and the driven wheel 333, the two sets of grinding rollers 32 rotate in opposite directions, and the grinding teeth 321 on the two sets of grinding rollers 32 move alternately to grind the fungal mud.

[0046] Finished product discharge: The ground material is discharged through discharge pipe 312 and transported to the subsequent lactobacillus homogenizing equipment.

[0047] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
