Description

Technical Field

[0001] This utility model relates to the field of fermented bean curd technology, and in particular to a ventilation device in the fermentation process of fermented bean curd. Background Technology

[0002] Fermented bean curd is a fermented soy product, beloved for its delicious taste and high nutritional value. It's a timeless delicacy. The processing of fermented bean curd involves using a fermentation device to ferment the starter culture. Currently, when using this fermentation device, the fermentation sieve containing the soy product is typically placed directly onto a support frame for natural fermentation.

[0003] A search revealed Chinese Patent Publication No. CN221344559U, which discloses a prefabricated fermentation device for fermented bean curd. This device features a fan installed in a rotating trough, air vents on the side wall of the outer casing near the loading drawers, and a filter box on the side wall of the outer casing near the air vents. The fan blows air into the outer casing, creating a more even airflow that circulates from bottom to top. This ensures that multiple loading drawers and fermentation sieves are within the circulating airflow, thereby improving fermentation quality. The airflow, after being filtered through the air vents and the filter box, prevents any odor from escaping. The entire device provides a favorable fermentation environment for the fermented bean curd culture.

The two end faces of the rotating groove 12 are mesh structures, and air circulation is achieved by blowing air into the interior of the device housing 1 through the internal fan.

[0032] Reference Figure 1 - Figure 2A bracket 2 is fixedly connected to the side wall of the device housing 1. The bracket 2 is used to provide support and a platform for the ventilation component 3. The ventilation component 3 is provided on the surface of the bracket 2. The ventilation component 3 includes a filter box 31. The filter box 31 is placed on the surface of the bracket 2. A guide rail 32 is fixedly connected to the inner wall of the filter box 31. A dustproof net 321 is fixedly connected to the side wall of the filter box 31. The dustproof net 321 is used to block dust and prevent dust from entering the filter box 31. A slot 33 is opened on the top of the filter box 31. An activated carbon filter plate 34 is inserted into the slot 33 and the guide rail 32. The slot 33 is used for inserting the activated carbon filter plate 34 into the filter box 31 and positioning the activated carbon filter plate 34 through the guide rail 32 to ensure that the activated carbon filter plate 34 is in a vertical state. The activated carbon filter plate 34 adsorbs the odor produced by fermentation of fermented bean curd and ensures that the outflowing air is fresh. The top of the activated carbon filter plate 34 is located on the outside of the filter box 31, which facilitates the replacement of the activated carbon filter plate 34.

[0033] Reference Figure 2 - Figure 3 A horizontal plate 35 is attached to the top of the activated carbon filter plate 34. A groove 36 is formed on the surface of the horizontal plate 35, and two sets of symmetrically arranged movable plates 37 are slidably connected inside the groove 36. The two sets of movable plates 37 are threaded together by a bidirectional threaded rod 38, which passes through and is rotatably connected to the side wall of the horizontal plate 35. A handwheel 39 is fixedly connected to the end of the bidirectional threaded rod 38. A handle is provided at the top of the horizontal plate 35. By rotating the handwheel 39, the rotation of the bidirectional threaded rod 38 is controlled, causing the two sets of movable plates 37 to move towards each other or away from each other, adjusting the distance between the two sets of movable plates 37. A clamping plate 310 is fixedly connected to the bottom end of the movable plate 37, and the clamping plate 310 is attached to the side wall of the activated carbon filter plate 34. The movable plate 37 drives the clamping plate 310 to move synchronously, so that the clamping plate 310 can clamp and fix the top of the activated carbon filter plate 34. Through the handle at the top, the horizontal plate 35 and the activated carbon filter plate 34 are pulled out together, and the clamping and fixing effect of the clamping plate 310 on the activated carbon filter plate 34 is released, so that the activated carbon filter plate 34 can be removed, making it easy to replace the new activated carbon filter plate 34.

[0034] Reference Figure 1 - Figure 2A cleaning assembly 4 is provided on the inner wall of the filter box 31. The cleaning assembly 4 includes guide rods 41, two sets of which are symmetrically arranged. Both sets of guide rods 41 are fixedly connected to the inner wall of the filter box 31. Connecting seats 42 are slidably connected to the outer wall of the guide rods 41. A fixing plate 43 is fixedly connected between the two sets of connecting seats 42. The guide rods 41 guide the connecting seats 42, allowing the connecting seats 42 to move vertically. The fixing plate 43 fixes the two sets of connecting seats 42 together, allowing the two sets of connecting seats 42 to move synchronously. A through hole is opened on the surface of the fixing plate 43, and a positioning rod 44 is slidably connected in the through hole. A cleaning brush 45 is fixedly connected to the end of the positioning rod 44. The cleaning brush 45 is elastically connected to the fixing plate 43 through a support spring 46. The positioning rod 44 is used to position the cleaning brush 45 and make the cleaning brush 45 move synchronously with the fixing plate 43. The support spring 46 supports the cleaning brush 45, making it fit tightly against the surface of the dustproof net 321. By moving the fixing plate 43 up and down, the cleaning brush 45 cleans the dustproof net 321 and maintains the ventilation effect of the dustproof net 321.

[0035] Working principle: The fan inside the rotating slot 12 blows air into the housing 1, achieving airflow. The ventilation component 3 filters the outflowing air. When the activated carbon filter plate 34 needs to be replaced, the handle on the top of the horizontal plate 35 is used to pull out the horizontal plate 35 and the activated carbon filter plate 34 together. By rotating the handwheel 39, the rotation of the bidirectional threaded rod 38 is controlled, causing the two sets of movable plates 37 to move towards each other or away from each other. Adjusting the distance between the two sets of movable plates 37 releases the clamping effect of the clamping plate 310 on the activated carbon filter plate 34, allowing the activated carbon filter plate 34 to be removed for easy replacement with a new one. Furthermore, the support spring 46 supports the cleaning brush 45, ensuring it is in close contact with the surface of the dustproof net 321. By moving the fixed plate 43 up and down, the cleaning brush 45 cleans the dustproof net 321, maintaining the ventilation effect of the dustproof net 321.
