Description

Technical Field

[0001] This utility model relates to the field of bioengineering technology, specifically a multi-layer fermenter for fermenting plum enzymes. Background Technology

[0002] With the development of bioengineering, food science, and the health industry, people's demand for healthy drinks and functional foods is constantly increasing. As a health product rich in natural organic acids and enzymes, plum enzyme is becoming increasingly popular among consumers. In order to improve the production efficiency and quality of plum enzyme, traditional single-layer fermentation tanks often cannot meet the needs. The emergence of multi-layer fermentation tanks for plum enzyme fermentation is precisely to meet the multiple requirements of modern food industry for production efficiency, product quality, automation, and environmental protection. It not only meets the needs of large-scale production, but also optimizes the fermentation process, improves product quality, saves resources, and conforms to the trend of modern sustainable development.

[0003] According to Chinese Utility Model Publication No. CN214881375U, a fermentation tank for plum production is disclosed. By setting up a mixing mechanism and an assembly mechanism, the mesh frames can hold the plums, effectively preventing plum pulp residue from remaining in the tank after fermentation, which would be inconvenient to clean. The locking mechanism between the slots and the locking plates can initially lock and position the four sets of mesh frames. Simultaneously, the threaded connection between the threaded rod and the threaded sleeve can position the cross-shaped base plate, providing support and secondary limiting for the mesh frames. At the same time, the motor drives the rotating shaft to rotate, thereby synchronously rotating the four sets of mesh frames through the locking seats. This allows the plum pulp to be evenly mixed with yeast, effectively preventing uneven sugar distribution. This device, while preventing plum residue from remaining in the fermentation tank, can simultaneously mix plums and yeast, improving the yeast proliferation rate. The system features a combination of temperature control and heat dissipation, allowing for more even sugar distribution. Limiting blocks and slots enable quick engagement and positioning of the cross-shaped base plate with the mesh frame, facilitating unobstructed entry of the threaded rod into the threaded sleeve and improving work efficiency. Reinforcing columns enhance the stability of the cross-shaped base plate, thereby improving the overall stability of the four mesh frames. A solenoid valve controls the opening and closing of the discharge pipe, regulating its flow rate and preventing material from falling during fermentation. A circulation pipe and connecting pipe allow for the circulation of external condensate, controlling the temperature within the fermentation tank and preventing excessive heat from affecting fermentation. A square ring facilitates lifting the tank lid, enabling quick cleaning of plum residue within the mesh frame. A rotating handle allows for rapid rotation of the threaded rod, increasing assembly speed.

[0004] However, the following problems exist when implementing the above technical solutions: the fermentation tank of the device is a fixed structure, which does not make full use of space. The tank can only hold a limited amount of raw materials, and it cannot flexibly carry out production according to the required output, which reduces production efficiency and wastes time and costs.
