AI Technical Summary
In the existing multi-layer fermented bean curd fermentation rack, the contact area between the bottom of the fermentation frame and the air is too small, resulting in uneven fermentation of the fermented bean curd. In addition, the soft fermented bean curd is easily deformed due to vibration, affecting the appearance and quality.
A multi-layer fermented bean curd fermentation rack was designed, which adopted structures such as sliding sleeves, sliding columns, connecting columns and shock-absorbing rubber rings to ensure that there is a gap between the fermentation frame and the supporting plate. The temperature and humidity were controlled by heaters and humidifiers, and the placement and removal of the fermentation frame were facilitated by limiting components.
The uniformity and efficiency of fermentation of fermented bean curd are improved, the impact of vibration on the fermented bean curd is reduced, and the appearance and quality of the fermented bean curd are guaranteed.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of fermented bean curd, in particular to a multi-layer fermented bean curd fermentation rack. Background Art
[0002] Fermented bean curd is a traditional Chinese fermented soy product made from soybeans through a series of processes, including refining, dough-making, incubation, and fermentation. It boasts a long history and a unique flavor, and can be enjoyed on its own or as a cooking condiment. Rich in protein, minerals, unsaturated fatty acids, and B vitamins, fermented bean curd is beneficial to human health, but consumption should be moderate, especially for those with hypertension and kidney disease. Fermented bean curd should be stored in a cool, dry place and kept tightly sealed.
[0003] When fermenting fermented bean curd, it is necessary to maintain appropriate temperature and humidity, for which a multi-layer fermented bean curd fermentation rack is required.
[0004] When the current multi-layer fermented bean curd fermentation rack is used, tofu inoculated with Mucor fungi is usually placed in a fermentation frame, and then the fermentation frame is directly placed on the horizontal frame of the fermentation frame. Although ventilation grooves are provided on the horizontal frame of the fermentation frame to ensure that the bottom of the tofu can also come into contact with air, in actual use, the ventilation grooves of the bottom of the fermentation frame and the horizontal frame of the fermentation frame overlap, resulting in an area that can be ventilated that is too small, so that the bottom of the tofu has less contact with moist air, resulting in uneven fermentation of the fermented bean curd, affecting the fermentation quality of the fermented bean curd. At the same time, fermented bean curd is generally relatively soft, and will be deformed after being impacted, resulting in poor appearance of the fermented bean curd. Therefore, a multi-layer fermented bean curd fermentation rack is proposed to solve the above problems. Utility Model Content

A sliding sleeve 12 is fixedly connected to the bottom of the bearing plate 6. Four groups of sliding sleeves 12 are provided, which are respectively arranged at the four corners of the bottom of the bearing plate 6. An annular groove 13 is opened on the inner wall of the side of the sliding sleeve 12. There are five groups of annular grooves 13, which are linearly and equidistantly arranged on the inner wall of the side of the sliding sleeve 12. A connecting column 14 is passed through and slidably connected to the top of the sliding sleeve 12. There is a certain gap between the inner wall of the sliding sleeve 12 and the connecting column 14. A shock-absorbing rubber ring 15 is fixedly connected to the outer peripheral surface of the bottom end of the connecting column 14. The shock-absorbing rubber ring 15 has a certain elasticity. When the shock-absorbing rubber ring 15 is squeezed, it can deform and generate elastic force. In a stable state, the outer peripheral surface of the shock-absorbing rubber ring 15 is clamped inside the inner ring groove 13 in the middle.
[0033] Reference Figures 2-4 The top of the connecting column 14 is fixedly connected with a connecting assembly, which is used to fix the fermentation frame. The connecting assembly includes a fixing plate 16 that plays a fixed connection role. The bottom end of the fixing plate 16 is fixedly connected to the top of the connecting column 14. A circular groove is opened on the front of the fixing plate 16 to facilitate fixing the fermentation frame by bolts. The bottom of the fixing plate 16 is fixedly connected to the top of the sliding column 17. The bottom of the connecting assembly is fixedly connected to a sliding column 17. The outer peripheral surface of the sliding column 17 passes through and is slidably connected to the inner wall of the bottom end of the supporting plate 6. The supporting plate 6 limits the inner wall of the sliding column 17 from sliding up and down. A buffer spring 18 is provided on the outer periphery of the sliding column 17. One end of the buffer spring 18 is fixedly connected to the bottom of the fixing plate 16, and the other end of the buffer spring 18 is fixedly connected to the inner wall of the bottom end of the supporting plate 6. When the fixing plate 16 is not under force, the buffer spring 18 will push the fixing plate 16 upward.
[0034] Reference Figure 1 、 Figure 4 and Figure 5The front of the carrying plate 6 is fixedly connected to the limit assembly, which is used to limit the position of the carrying plate 6. The limit assembly includes a limit seat 8, the back of the limit seat 8 is fixedly connected to the front of the carrying plate 6, and the limit seat 8 is provided with two groups, which are symmetrically arranged on the left and right sides of the carrying plate 6. A limit groove 9 is opened inside the limit seat 8, and the inner wall of the limit groove 9 is elastically connected to the limit card block 11 by a limit spring 10. When the limit card block 11 is not under force, the limit spring 10 will push the limit card block 11 outward. One end of the limit spring 10 is fixedly connected to the inner side of the limit groove 9, and the other end of the limit spring 10 is fixedly connected to the inner side of the limit card block 11. The outer periphery of the limit card block 11 is slidably connected to the inside of the limit groove 9. The limit groove 9 limits the limit card block 11 to slide left and right along the inner wall of the limit groove 9. The inner walls of the left and right sides of the cabinet 1 are provided with card slots 4, and the outer peripheral surface of the limit card block 11 is carded in the inside of the card slot 4, thereby fixing the carrying plate 6.
[0035] Working principle: when you want to ferment tofu, place the fermentation frame containing tofu inside the fixed plate 16 and fix it with bolts. At this time, there is a certain gap between the fermentation frame and the inner wall of the bottom end of the supporting plate 6, so that the water vapor of the humidifier 3 can pass through the ventilation groove 7 in the middle of the supporting plate 6 and contact the bottom of the tofu in the fermentation frame. At the same time, the water vapor can pass through the front and back of the gap between the fermentation frame and the inner wall of the bottom end of the supporting plate 6, so as to be evenly distributed inside the cabinet 1. At the same time, when the cabinet 1 is vibrated, the vibration is transmitted to the supporting plate 6, and the supporting plate 6 vibrates up and down, causing the supporting plate 6 to squeeze the buffer spring 18. The buffer spring 18 compresses to produce buffering and releases compression at the same time, generating rebound, and at the same time drives the connecting column 14 to slide up and down along the inner wall of the sliding sleeve 12. The connecting column 14 drives the shock-absorbing rubber ring 15 to slide up and down, and is squeezed by the annular groove 13, resulting in deformation and resistance, offsetting the vibration of the buffer spring 18, thereby reducing the impact of the vibration on the soft tofu and ensuring the complete shape of the tofu. When you want to take out the fermentation frame conveniently, push the limit block 11 inward, the limit block 11 moves inward, and squeezes the limit spring 10. At this time, the limit block 11 is out of contact with the card slot 4 and the lock is released. At this time, pull the supporting plate 6 outward, so that the fermentation frame can be easily taken out.
[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
