Description

Technical Field

[0001] This utility model relates to the field of food fermentation technology, specifically to a quantitative food fermentation device. Background Technology

[0002] In actual food processing, a large number of foods are pickled or fermented, such as some kimchi. Vegetables need to be placed in jars, and the common method is to seal them with water. Suitable temperature and closed environment are required. Usually, after the actual fermentation is completed, the introduction of bacteria from the air should be minimized.

[0003] The utility model patent with publication number CN221777842U discloses a quantitative food fermentation device, which solves the problems of current food fermentation devices, such as inconvenience in achieving closed quantitative supply, food exposure during fermentation, increased susceptibility to spoilage, poor internal liquid flow, and poor fermentation uniformity. It uses a supply drive motor to rotate a drive auxiliary wheel with a discharge groove on its surface to quantitatively remove food from the fermentation tank. While this method is structurally simple, in actual use, when the discharge groove opening faces downwards, food is discharged from the discharge groove, allowing air from the external environment to enter. As the drive auxiliary wheel rotates, this external air is drawn into the fermentation tank, making the food in the fermentation tank prone to spoilage during frequent handling.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1.

A discharge pipe 5 is fixedly connected to the bottom of the fermentation tank 1, and the quantitative discharge assembly 4 is located inside the discharge pipe 5. An electric heating plate 6 is fixedly connected to the inner wall of the discharge pipe 5. The number of electric heating plates 6 is several, and the electric heating plates 6 are evenly distributed in a ring on the inner wall of the discharge pipe 5. The bottom of the fermentation tank 1 is fixedly connected to a second vacuum pump 8. The air inlet pipe of the second vacuum pump 8 extends into the interior of the discharge pipe 5. The bottom of the discharge pipe 5 is connected to a discharge valve 9. The surface of the sealing cover 2 is provided with a liquid seal assembly 10. Valves are provided on the air inlet pipes of the first vacuum pump 7 and the second vacuum pump 8. The first vacuum pump 7 and the second vacuum pump 8 mentioned above are similar in principle to the suction vacuum pump mentioned in the utility model patent of CN221777842U, which is a quantitative food fermentation device, and achieve the same effect. This application will not elaborate on them in detail. The electric heating plates 6 mentioned above are existing mature technologies, and this application will not elaborate on them in detail.

[0022] refer to Figure 2 and Figure 4 The quantitative feeding assembly 4 includes a quantitative box 12 fixedly connected inside the inlet 11.

A first motor 15 is fixedly connected to the bottom of the fermentation tank 1. The output end of the first motor 15 is fixedly connected to the quantitative wheel 13.

[0023] As a technical optimization of this utility model, by setting up the quantitative discharge component 4, the operator can start the first motor 15 to rotate and drive the quantitative wheel 13 to rotate. When the opening of the quantitative groove 14 on the surface of the quantitative wheel 13 rotates to the top, the food in the fermentation tank 1 falls into the quantitative groove 14. The volume of the quantitative groove 14 is fixed, so the volume of food that the quantitative groove 14 can hold each time is basically fixed. The rotation of the quantitative wheel 13 drives the food in the quantitative groove 14 to rotate around the axis of the quantitative wheel 13. When the opening in the quantitative groove 14 is downward, the food in the quantitative groove 14 falls into the discharge pipe 5.

[0024] refer to Figures 1 to 3 The stirring assembly 3 includes a second motor 16 fixedly connected to the top of the sealing cover 2, and a stirring rod 17 rotatably connected inside the sealing cover 2. The output end of the second motor 16 is fixedly connected to the stirring rod 17.

[0025] As a technical optimization of this utility model, by setting the stirring component 3, the operator can start the second motor 16 to rotate and drive the stirring rod 17 to rotate, thereby stirring the food in the fermentation tank 1 and improving the fermentation effect of the food in the fermentation tank 1.

[0026] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 The liquid seal assembly 10 includes a first liquid seal frame 18 fixedly connected to the surface of the sealing cover 2, and a second liquid seal frame 19 fixedly connected to the surface of the fermenter 1.

[0027] As a technical optimization of this utility model, by setting up the liquid seal assembly 10, after the operator installs the sealing cover 2, the bottom of the first liquid seal frame 18 on the surface of the sealing cover 2 is inserted into the second liquid seal frame 19. There is a small gap between the bottom of the first liquid seal frame 18 and the bottom of the inner wall of the second liquid seal frame 19. Then, the operator adds water to the liquid seal cavity formed between the second liquid seal frame 19 and the fermentation tank 1. The water level is higher than the bottom height of the first liquid seal frame 18, but lower than the top height of the second liquid seal frame 19. The liquid seal prevents external air from entering the fermentation tank 1 from the gap between the sealing cover 2 and the fermentation tank 1, thereby improving the sealing effect of the fermentation tank 1.

[0028] refer to Figure 1 and Figure 2 A support ring 20 is fixedly connected to the surface of the fermentation tank 1, and a support frame 21 is fixedly connected to the surface of the support ring 20. There are several support frames 21, which are evenly distributed in a ring on the surface of the support ring 20.

The discharge pipe 5 is fixedly connected to the second bearing, and the outer ring of the second bearing is fixedly connected to the discharge pipe 5, and the inner ring of the second bearing is fixedly connected to the output shaft of the second motor 16. Both the first bearing and the second bearing are provided with sealing shaft covers.

[0031] As a technical optimization of this utility model, by setting the first bearing and the second bearing, on the one hand, it can facilitate the rotation of the stirring rod 17 and the output shaft of the second motor 16, and on the other hand, it can improve the sealing between the sealing cover 2 and the stirring rod 17 and the sealing between the discharge rack and the output shaft of the second motor 16.

[0032] The working principle and usage process of this utility model are as follows: During use, fermentation tank 1 can be used to pickle foods such as diced radishes. When the operator takes a quantitative amount of food from fermentation tank 1, the operator first closes the discharge valve 9, then starts the electric heating plate 6 to heat and sterilize the environment inside the discharge pipe 5, and then starts the second vacuum pump 8 to extract the air from the discharge pipe 5. This cools the environment inside the discharge pipe 5 and reduces the possibility of bacteria or viruses in the air inside the discharge pipe 5, thereby ensuring the cleanliness of the internal environment of the feed pipe. After the environment inside the discharge pipe 5 has cooled down, the operator uses the quantitative discharge component 4 to quantitatively transport the food from fermentation tank 1 into the discharge pipe 5. Then, the operator adjusts the quantitative groove 14 on the surface of the quantitative wheel 13 to rotate to the position with the opening facing upward. Then, the operator opens the discharge valve 9 to allow the food inside the discharge pipe 5 to be discharged from the discharge pipe 5. At this time, the environment inside the discharge pipe 5 comes into contact with the external environment. Then, the operator closes the discharge valve 9 and repeats the cycle to sterilize the environment inside the discharge pipe 5.

[0033] The operator can install temperature and pressure detectors inside the discharge pipe 5 to monitor the temperature and pressure inside the discharge pipe 5. Through external control components, it is easy to control the start and stop of the electric heating plate 6 and the second vacuum pump 8. Through the setting of the first vacuum pump 7, this device can extract the air in the fermentation tank 1, further reduce the bacteria in the air inside the fermentation tank 1, and further improve the preservation period.
