Description

Technical Field

[0001] The utility model relates to the technical field of fermentation tanks, in particular to a lactic acid bacteria fermentation tank. Background Art

[0002] Lactic acid fermentation is actually the anaerobic respiration of lactic acid bacteria. In higher plants, anaerobic respiration is often called fermentation. This process does not involve molecular oxygen. When the incomplete oxidation product after oxidation is alcohol, it is called alcohol fermentation; when it is lactic acid, it is called lactic acid fermentation. Yogurt is one of the common foods made through fermentation. Yogurt, also known as sour milk, is made from milk as the main raw material and fermented by lactic acid bacteria. Under anaerobic conditions, the original natural lactic acid bacteria in milk or artificially added lactic acid bacteria can decompose the lactose in milk to produce a large amount of lactic acid, causing the pH value of milk to drop and the milk to become sour. The acidic conditions can cause the casein in the milk to coagulate and precipitate, so that the milk begins to thicken and becomes sour and thick yogurt.

[0003] When lactic acid bacteria are fermented, a fermentation tank is usually used for fermentation. The current lactic acid bacteria fermentation tank uses an internal stirring mechanism to mix milk and lactic acid bacteria. Since the internal stirring mechanism only relies on a stirring shaft for stirring, although the purpose of stirring is achieved, the yogurt at the bottom of the fermentation tank is difficult to be fully stirred, resulting in insufficient fermentation. Therefore, we propose a lactic acid bacteria fermentation tank. Summary of the invention

[0029] Reference Figure 1-5The utility model provides a lactic acid bacteria fermentation tank, including a tank body 1, a support frame 8 is fixedly connected to the circumferential surface of the lower end of the tank body 1, an end cover 6 is fixedly connected to the upper end of the tank body 1, a feeding port 7 is fixedly connected to the upper end of the end cover 6, a stirring mechanism 5 and a cleaning mechanism 9 are arranged inside the tank body 1, an auger 10 is rotatably connected to the lower end of the tank body 1, and the lower end of the auger 10 passes through the tank body 1, a plurality of auger 10 are arranged, and they are distributed in a circular array, a transmission assembly 2 is arranged at the lower end of the tank body 1, and the transmission assembly 2 is used to transmit power to the auger 10; a discharge pipe 3 is fixedly connected to the circumferential surface of the lower end of the tank body 1, and a valve 4 is installed on the discharge pipe 3.

[0030] Specifically, when in use, milk and lactic acid bacteria are added into the tank body 1 from the feeding port 7 in a certain proportion. After the materials are added, the feeding port 7 is sealed, and then the stirring mechanism 5 is operated to mix the milk and lactic acid bacteria in the tank body 1. At the same time, with the cooperation of the transmission component 2 and the auger 10, the milk and lactic acid bacteria at the bottom of the tank body 1 can be turned to the upper end, so that the milk and lactic acid bacteria in the upper and lower parts of the tank body 1 can be fully mixed, thereby improving the mixing efficiency and facilitating better fermentation of the milk; after the fermentation is completed, the valve 4 is opened, and the fermented yogurt is discharged from the discharge pipe 3; when cleaning is needed, the cleaning mechanism 9 can clean the inner wall of the tank body 1, thereby reducing the waste of yogurt.

[0031] In one embodiment, if Figure 2 As shown, the stirring mechanism 5 includes a motor 501, a rotating shaft 502 and a stirring rod 503. The end cover 6 and the inside of the tank body 1 are both rotatably connected with the rotating shaft 502. The circumferential surface of the rotating shaft 502 is fixedly connected with the stirring rod 503. The upper end of the end cover 6 is fixedly connected with the motor 501, and the output end of the motor 501 is fixedly connected with the stirring rod 503.

[0032] The motor 501 is working, and the stirring rod 503 can be driven to rotate under the action of the rotating shaft 502, and then the milk and the lactic acid bacteria can be mixed under the action of the stirring rod 503.

[0033] In one embodiment, if Figure 2-3 As shown, the transmission assembly 2 includes a protective cover 201, a first gear 202 and a second gear 203. The lower end of the rotating shaft 502 passes through the protective cover 201 and is rotatably connected to the protective cover 201.

[0034] As the rotating shaft 502 rotates, the auger 10 can be driven to rotate with the cooperation of the first gear 202 and the second gear 203. As the auger 10 rotates, the milk and lactic acid bacteria at the bottom of the tank body 1 can be turned to the upper end of the tank body 1, so as to facilitate the mixing of the milk and lactic acid bacteria in the upper and lower parts of the tank body 1, thereby improving the mixing efficiency and facilitating better fermentation of the milk.

[0036] When the fermentation tank needs to be cleaned, the electric telescopic rod 902 is extended, and the scraper 901 can be driven to move toward the inner wall of the fermentation tank under the cooperation of the moving rod 903, the connecting block 904 and the transmission rod 905. After the scraper 901 contacts the inner wall of the fermentation tank, the stirring mechanism 5 works to clean the inner wall of the fermentation tank, thereby reducing the waste of yogurt.

[0037] When cleaning is not needed, the electric telescopic rod 902 can be retracted to drive the scraper 901 away from the inner wall of the fermentation tank, so that during stirring, the scraper 901 is prevented from contacting the inner wall of the tank body 1 for a long time, thereby increasing the service life of the scraper 901.

[0038] Among them, Figure 4 As shown, a telescopic rod 11 is fixedly connected to the circumferential surface of the rotating shaft 502, and one end of the telescopic rod 11 away from the rotating shaft 502 is fixedly connected to the scraper 901. By setting the telescopic rod 11, the movement of the scraper 901 can be limited under the action of the telescopic rod 11, so that the scraper 901 can only move horizontally.
