Description

Technical Field

[0001] This utility model relates to the technical field of fermented bean curd production equipment, specifically a multi-layer three-dimensional culture rack device for cultivating Mucor mold in fermented bean curd. Background Technology

[0002] In the industrial production of fermented bean curd, the requirements for space utilization and flexibility of equipment in the Mucor cultivation process are becoming increasingly stringent. Traditional single-layer Mucor cultivation racks, due to their limited floor plan layout, require a large amount of factory space for large-scale production, resulting in high costs for equipment procurement and site rental. Furthermore, they are difficult to adapt to different sizes of cultivation containers, severely restricting the improvement of production efficiency.

[0003] While existing multi-layer culture racks offer some improvement in space utilization, the fixed spacing between layers fails to meet the diverse space requirements of Mucor culture at different stages. In the early stages of Mucor growth, the culture containers are relatively low, and excessively wide spacing between layers wastes space. In the later stages, when mycelial growth is vigorous, narrow spacing can hinder airflow and mycelial extension, and may even make it difficult to remove the culture containers, affecting subsequent procedures.

[0004] Furthermore, traditional culture racks often require rebuilding or replacing the entire rack structure when changing to different sized culture containers. This is cumbersome, time-consuming, and labor-intensive, increasing labor costs and potentially damaging equipment components due to frequent disassembly and assembly, thus shortening the equipment's lifespan. Therefore, developing a multi-layered culture rack device with adjustable shelf height is crucial for optimizing the cultivation process of *Mucor rotten* and promoting industrial upgrading. In light of this, we propose a multi-layered, three-dimensional culture rack device for *Mucor rotten* cultivation. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a multi-layer three-dimensional culture rack device for culturing Mucor rot.

[0006] The technical solution of this utility model is:

[0007] A multi-layer three-dimensional culture rack device for cultivating *Mucor* fungi in fermented bean curd includes a culture box and a culture rack installed inside the culture box. The culture rack includes several parallel placement plates. The outer ring wall of each placement plate is tightly fitted to the inner wall of the culture box. A temperature and humidity sensor is installed on the top of each placement plate. Two lifting rods are symmetrically arranged between two adjacent placement plates. Each lifting rod includes an outer rod, and a threaded rod is slidably installed inside the outer rod. A knob that is threaded to the outer wall of the threaded rod is rotatably installed on the top of the outer rod. The outer rod and the threaded rod are respectively fixed to the upper and lower placement plates. A mounting frame is fixedly connected to the bottom of each placement plate. Several heating rods are installed inside the mounting frame. Two doors are symmetrically installed on the front side of the culture box via hinges.

[0008] As a preferred technical solution, a guide rod is fixedly connected to each of the four corners of the incubation box. The guide rod passes through the placement plate and can ensure that the placement plate remains stable during the lifting and lowering process, preventing it from tilting or shaking.

[0009] As a preferred technical solution, the top of the incubator is fixed with the mounting frame, and several heating rods are installed in the mounting frame to provide heat to the incubator from the top, making the temperature inside the incubator more uniform.

[0010] As a preferred technical solution, a heating box is fixedly connected to the rear outer wall of the incubator. Several air outlet pipes are installed on the heating box.

Heated air can enter the incubator evenly through the air outlet pipes and the exhaust hood to promote air circulation.

[0011] As a preferred technical solution, each of the air outlet pipes is equipped with an air pump. The interior of the heating box is divided into several heating zones by several partitions. Each air outlet pipe is connected to each heating zone. The air pump can control the air velocity and flow rate. Different heating zones can heat the air in separate zones, thereby improving heating efficiency and temperature control accuracy.

[0012] As a preferred technical solution, each heating zone is fixedly equipped with several vertically arranged heating nets, which are used to heat the air.

[0013] As a preferred technical solution, the heating box has an air inlet on the outer wall away from the air outlet pipe, and a filter screen is fixedly installed on the outside of the air inlet. The filter screen can filter out dust and impurities in the air and prevent them from entering the incubator and contaminating the mold culture environment.

[0014] As a preferred technical solution, a support leg is fixedly installed at each of the four corners of the bottom of the incubator, and each placement plate has a downward recess on its top. The support leg can support the incubator and make it more stable, and the recess on the top of the placement plate can prevent the culture container from sliding.

[0028] like Figure 1 , Figure 3 and Figure 6As shown, a multi-layer three-dimensional culture rack device for cultivating *Mucor* fungus includes a culture box 100 and a culture rack installed inside the culture box 100. The culture rack consists of several parallel placement plates 101. The outer ring wall of the placement plate 101 is tightly fitted to the inner wall of the culture box 100, ensuring the relative sealing of the cultivation space. A temperature and humidity sensor 102 is installed on the top of each placement plate 101 to monitor the temperature and humidity of that layer in real time. Two lifting rods 104 are symmetrically arranged between two adjacent placement plates 101. The lifting rod 104 includes an outer rod 1040, and a threaded rod 1041 is slidably installed up and down inside the outer rod 1040. A knob 1042 is rotatably installed on the top of the outer rod 1040 and threadedly connected to the outer wall of the threaded rod 1041. By rotating the knob 1042, the threaded rod 1041 can be moved up and down inside the outer rod 1040, thereby adjusting the distance between adjacent placement plates 101. The outer rod 1040 and the threaded rod 1041 are fixed to the upper and lower placement plates 101 respectively. Each placement plate 101 has a mounting frame 105 fixedly connected to its bottom. Several heating rods 106 are installed inside the mounting frame 105 to heat the layer. Two doors 300 are symmetrically installed on the front side of the incubator 100 via hinges 500, which facilitates the placement and removal of culture containers.

[0029] like Figure 3 As shown, it should be added that a guide rod 103 is fixedly connected to each of the four corners of the incubator 100. The guide rod 103 passes through the placement plate 101 and plays a guiding and stabilizing role during the lifting and lowering of the placement plate 101.

[0030] like Figure 4 As shown, in a preferred embodiment, the top of the incubator 100 is fixed with a mounting frame 105, and a plurality of heating rods 106 are installed inside the mounting frame 105, which can heat the inside of the incubator 100 from the top, making the temperature inside the chamber more uniform.

[0031] like Figure 2 As shown, in a preferred embodiment, a heating box 200 is fixedly connected to the rear outer wall of the incubator 100. Several air outlet pipes 201 are installed on the heating box 200. An exhaust hood 203 is fixedly installed at the end of the air outlet pipe 201 away from the heating box 200. The exhaust hood 203 communicates with the interior of the incubator 100. The heated air can enter the incubator 100 evenly through the air outlet pipe 201 and the exhaust hood 203.

[0032] like Figure 5As shown, in a preferred embodiment, each air outlet pipe 201 is equipped with an air pump 202. The interior of the heating box 200 is divided into several heating zones 205 by several partitions 206. Each air outlet pipe 201 is connected to each heating zone 205. The air pump 202 can control the air velocity and flow rate. Different heating zones 205 can heat the air in separate zones, thereby improving heating efficiency and temperature control accuracy.

[0033] like Figure 5 As shown, in a preferred embodiment, each heating zone 205 is fixedly equipped with several vertically arranged heating meshes 204, which are used to heat the air.

[0034] like Figure 2 As shown, in a preferred embodiment, the heating box 200 has an air inlet on the outer wall away from the air outlet pipe 201. A filter screen 2001 is fixedly installed on the outer side of the heating box 200 outside the air inlet. The filter screen 2001 can filter out dust and impurities in the air and prevent them from entering the incubator 100 and contaminating the mold culture environment.

[0035] like Figure 1 and Figure 3 As shown, in a preferred embodiment, a support leg 400 is fixedly installed at each of the four corners of the bottom of the incubator 100, and each placement plate 101 has a downward recess at the top. The support leg 400 can support the incubator 100, making it more stable, and the recess at the top of the placement plate 101 can prevent the culture container from sliding.

[0036] In use, the multi-layer three-dimensional culture rack device for cultivating *Mucor* mold in fermented bean curd is first adjusted by rotating the knob 1042 on the lifting rod 104 according to the specifications of the culture container. Then, the door 300 is opened, and the culture container containing the *Mucor* culture medium is placed on the placement plate 101. After closing the door 300, the temperature and humidity of each layer are monitored in real time by the temperature and humidity sensor 102. When temperature adjustment is needed, the heating rods 106 at the bottom of the placement plate 101 and in the mounting frame 105 at the top of the culture box 100 can be activated. Simultaneously, the heating grid 204 and air pump 202 inside the heating box 200 are activated. The heated air enters the culture box 100 through the air outlet pipe 201 and the exhaust hood 203, promoting air circulation and making the temperature inside the box more uniform. When air enters the heating box 200, the filter screen 2001 filters out dust and impurities, ensuring a clean cultivation environment. During the cultivation process, the temperature and humidity can be adjusted at any time according to the actual situation to meet the optimal conditions for *Mucor* growth.
