Description

Technical Field

[0001] This utility model relates to the field of fermented bean curd processing, and in particular to a pickling device for fermented bean curd production. Background Technology

[0002] Fermented bean curd, also known as tofu curd, is a condiment or side dish made from soybeans as the main raw material. It is processed by grinding soybeans into a paste, shaping the bean curd, cultivating bacteria, fermenting, and then marinating it with salt and various spices. In order to make the texture of fermented bean curd firmer, more delicate, and the taste more mellow, a marinating device is required during the processing of fermented bean curd.

[0003] A search revealed Chinese Patent Publication No. 202320068680.5, which discloses a pickling device for making fermented bean curd. The device involves rotating the top cover using a handle, causing the twisted thread to separate from the connecting thread. Pulling the top cover upwards moves the placement plate out of the pickling cylinder. Then, when the stress groove of the bottom plate and the through hole are at the same level, a support rod is pushed into the stress groove for support and fixation. This ensures that the raw materials on the top of the placement plate are fully observable, facilitating their removal or rearrangement, reducing damage caused by piling them together, saving working time, and increasing efficiency. Furthermore, the gas supply pipe and U-shaped pipe on the side wall of the pickling cylinder facilitate pressure relief during pickling, preventing excessive internal pressure.

[0004] In the existing technology, the above-mentioned device facilitates the subsequent observation of the fermented bean curd pickling process by moving the placement plate. However, in actual operation, it is necessary to twist the threads and separate from the connecting threads multiple times, which is cumbersome and makes it impossible to quickly move the placement plate out for observation. Therefore, a pickling device for fermented bean curd production is proposed to solve the above problems. Utility Model Content

[0035] Reference Figures 1-3This utility model provides an embodiment of a pickling device for fermented bean curd production, comprising a pickling barrel 1, a cover plate 2 detachably installed on the top of the pickling barrel 1, the cover plate 2 being installed on the top of the pickling barrel 1 using an existing installation method, a fixed shaft 3 fixedly connected to the inner wall of the top of the pickling barrel 1, the middle of the fixed shaft 3 being hollow to allow a moving plate 7 to move along the middle of the fixed shaft 3, a sleeve 4 inserted into the outer wall of the fixed shaft 3, a placement frame 5 fixedly connected to the outer wall of the sleeve 4, on which the fermented bean curd to be pickled can be placed, the placement frame 5 having through holes to allow air circulation, a guide rod 6 fixedly connected to the inner wall of the sleeve 4, the guide rod 6 ensuring that the moving plate 7 moves laterally without deviation of the movement trajectory, a limit mechanism provided on the outer wall of the guide rod 6, and a ventilation component provided on the outer wall of the pickling barrel 1.

[0036] The limiting mechanism includes a movable plate 7, which has a certain length and extends to and is fixed to the wedge block 9. The movable plate 7 is slidably connected to the outer wall of the guide rod 6. The left end of the movable plate 7 is elastically connected to the sleeve 4 through a return spring 8. The right end of the movable plate 7 is fixedly connected to the wedge block 9, which is inclined. When the inclined surface is squeezed, the wedge block 9 will move the movable plate 7 laterally along the inner wall of the sleeve 4.

[0037] Reference Figures 1-2 and Figure 7 A ventilation box 10 is fixedly connected to the outer wall of the pickling barrel 1. The lower plate of the ventilation box 10 has a slot, allowing air to enter the pickling barrel 1 through the slot to aid in the fermentation of the fermented bean curd. A baffle plate 11 is slidably connected to the inner wall of the ventilation box 10. A block 13 is elastically connected to the inner wall of the left end of the baffle plate 11 via a positioning spring 12. A filter screen 14 is installed on the inner wall of the ventilation box 10 to block dust and prevent dust from adhering to the fermented bean curd during ventilation. The inner wall of the left end of the baffle plate 11 is connected to... One end of the positioning spring 12 is fixedly connected. When the insertion block 13 moves to the right, it will stretch the positioning spring 12. When resetting, the reverse elastic force of the positioning spring 12 will bring the insertion block 13 back to its original position. The other end of the positioning spring 12 is fixedly connected to the left end of the insertion block 13. The insertion block 13 is slidably connected to the inner wall of the baffle plate 11. The insertion block 13 is inserted into the side wall of the ventilation box 10. The side wall of the ventilation box 10 has a slot corresponding to the insertion block 13, which can satisfy the limitation of the insertion block 13 and its insertion on the baffle plate 11.

[0038] Reference Figures 4-6The left end of the movable plate 7 is fixedly connected to one end of the return spring 8. When the movable plate 7 moves to the left, it will compress the return spring 8. When resetting, the return spring 8 will use its reverse elastic force to move the movable plate 7 back to its original position. The other end of the return spring 8 is fixedly connected to the inner wall of the left end of the sleeve 4. The movable plate 7 passes through and slides on the inner wall of the sleeve 4. The wedge 9 is inserted into the inner wall of the fixed shaft 3. The fixed shaft 3 has a slot corresponding to the wedge 9, which allows the slot to be inserted into the wedge 9 to limit the entire sleeve 4 in one direction.

[0039] Working principle: First, to observe the fermentation of fermented bean curd on the placement frame 5, move the placement frame 5 upwards from the pickling barrel 1. Simply hold the sleeve 4 and move it upwards. The sleeve 4 will move the placement frame 5 upwards. As the sleeve 4 moves upwards, it will also move the guide rod 6, the moving plate 7, and the wedge 9 upwards. The upward movement of the wedge 9 will cause the groove of the fixed shaft 3 to press against the inclined surface of the wedge 9, causing the wedge 9 to move to the left along the inner wall of the sleeve 4 and compress the return spring 8. When the wedge 9 and the next groove of the fixed shaft 3 coincide, the reverse elastic force of the return spring 8 will move the moving plate 7 upwards. Move to the right, allowing wedge 9 to insert into the next slot of fixed shaft 3, unidirectionally limiting the entire sleeve 4 and placement frame 5. This allows staff to observe the fermented bean curd on different layers of placement frame 5 one by one. After observation, hold the upper end of sleeve 4 with your hand and move the moving plate 7 to separate the moving plate 7, along with wedge 9, from the slot of fixed shaft 3. Then move your hand downwards to reset sleeve 4 and placement frame 5 to their initial state. Finally, release the moving plate 7 and use the elasticity of the return spring 8 to reset the moving plate 7 and wedge 9 to the right, allowing wedge 9 to be inserted into the slot of fixed shaft 3.

[0040] When the baffle 11 needs to be opened according to the ventilation conditions of the fermented bean curd, simply move the insert 13 to the right and stretch the positioning spring 12 to separate the insert 13 from the side wall slot of the ventilation box 10. Then, move the baffle 11 and the insert 13 upward to open the slot on the ventilation box 10. When a limit is needed, simply release the insert 13 and use the reverse elastic force of the positioning spring 12 to reset the insert 13, allowing the insert 13 to be inserted into the side wall of the ventilation box 10. The ventilation volume can be controlled according to the degree of opening. If it is necessary to reset the baffle 11 to the desired position, the baffle 11 can be moved to the desired position. Figure 1 In the initial state, simply follow the steps described above.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
