[0002] Food microorganism fermentation is the process that food components are transformed into other substances by the metabolic activity of microorganism, so as to change the taste, flavor, texture, nutritional value and shelf life of food. Food microorganism fermentation device is a container that provides a good environment for the operation of a specific biochemical process of microorganism. Its principle is that through the rotation of the stirrer, the microorganism in the fermentation liquid and the nutrient substance are in full contact, and the sterile air is dispersed into small bubbles at the same time, so as to increase the gas-liquid contact area and improve the oxygen dissolution rate, meet the demand of oxygen for the growth and metabolism of aerobic microorganism, and promote the fermentation process.

[0003] In the solid state fermentation by using the fermentation device, the microorganism may only adhere to the surface of the substrate and is difficult to penetrate into the substrate to fully utilize the nutrient components. Since there is only stirring structure on the fermentation device but no extrusion structure, the contact between the microorganism and the fermentation substrate is not close enough, which will cause the growth and metabolism speed of the microorganism to be relatively slow, prolong the fermentation period, and extend the fermentation time and reduce the production efficiency.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0028] Reference Figures 1-8 The food microorganism fermentation device provided by the embodiment comprises a fermentation tank 1, a feed inlet 2 and a discharge outlet 3 are arranged at the top and bottom of the fermentation tank 1 respectively, a stirring assembly 4 is arranged at the top of the fermentation tank 1, a temperature control assembly 5 is arranged outside the fermentation tank 1, a pressing plate mechanism 6 for improving fermentation efficiency and cleaning the tank wall is arranged on the fermentation tank 1, a pressure relief pipe 7 is arranged on the fermentation tank 1, and a pressure relief valve 8 is arranged on the pressure relief pipe 7, the stirring assembly 4 comprises a motor 42 arranged at the top of the fermentation tank 1 through a support 41, and a stirring blade 44 located in the interior of the fermentation tank 1 is arranged on the output end of the motor 42 through a connecting shaft 43, the temperature control assembly 5 comprises a jacket 51 forming a cavity with the fermentation tank 1, and an inlet pipe 52 and an outlet pipe 53 are arranged on the jacket 51 and communicate with the cavity.

[0029] In this invention, when using a fermentation device for food microbial fermentation, the fermentation raw materials are fed into the fermentation tank 1 through the feed inlet 2. The motor 42 on the support 41 is started, driving the stirring blades 44 on the connecting shaft 43 to rotate. The rotating stirring blades 44 ensure that the microorganisms and nutrients in the fermentation liquid are in full contact, while simultaneously dispersing the introduced sterile air into tiny bubbles, increasing the gas-liquid contact area, improving the oxygen dissolution rate, meeting the oxygen requirements for the growth and metabolism of aerobic microorganisms, and promoting the fermentation process. During the fermentation process, a heat medium can be introduced into the cavity between the jacket 51 and the fermentation tank 1 through the inlet pipe 52, thereby heating the fermentation tank 1 and promoting the fermentation process. When the internal pressure of the fermentation tank 1 is too high, the pressure relief valve 8 is opened and the pressure relief pipe 7 is used to relieve the pressure. The pressure plate mechanism 6 inside the fermentation tank 1 is used to squeeze the fermentation material to promote the fermentation process. The fermented material can be discharged through the discharge port 3.

[0030] Specifically, such as Figures 2-5 As shown, the pressing plate mechanism 6 includes a mesh plate 61 disposed inside the fermentation tank 1. The mesh plate 61 moves along its height direction inside the fermentation tank 1 via a moving component 62. The moving component 62 includes a connecting frame 621 that passes through the top of the fermentation tank 1 and is connected to the mesh plate 61. A spring 623 that abuts against the top of the fermentation tank 1 is disposed on the connecting frame 621 via a limiting plate 622.

[0031] In normal use, the mesh plate 61 at the bottom of the connecting frame 621 is pressed against the inside of the fermentation tank 1 by the spring 623 on the limiting plate 622. At this time, the mesh plate 61 is higher than the feed inlet 2 and will not affect the addition of fermentation material. During the fermentation process, the operator can press down on the connecting frame 621 to squeeze the spring 623, causing the mesh plate 61 to descend in the fermentation tank 1 and squeeze the fermentation material, making the fermentation material more compact. In this process, the contact between microorganisms and fermentation substrate is closer, allowing microorganisms to penetrate deeper into the raw material. This helps the fermentation material to come into more full contact with oxygen, nutrients, etc., thereby accelerating the growth and metabolism of microorganisms and improving fermentation efficiency.

[0032] Specifically, such as Figure 4 and Figure 6 As shown, the pressure plate mechanism 6 also includes a cleaning component 63. The cleaning component 63 includes a positioning plate 631 set on the mesh plate 61. The positioning plate 631 is provided with a cleaning brush 632 that abuts against the inner wall of the fermentation tank 1. The mesh plate 61 is provided with a mounting nut 612 that abuts against the positioning plate 631 through a positioning end 611. The positioning plate 631 is provided with a positioning hole 633 that cooperates with the positioning end 611.

[0033] The positioning plate 631 on the net plate 61 is detachably connected with the net plate 61 through the mounting nut 612 on the positioning end head 611 and the positioning hole 633, so that the maintenance and replacement are facilitated, the cleaning brush 632 on the positioning plate 631 moves along with the net plate 61 during the movement of the net plate 61 and brushes and cleans the inner wall of the fermentation tank 1, removes the residues and dirt attached to the wall, keeps the fermentation environment clean and sanitary, helps to reduce the breeding and pollution of miscellaneous bacteria and guarantees the purity and stability of the fermentation process.

[0034] The above merely describes a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
