Description

Fermentation tank structure Technical Field The utility model relates to the technical field of fermentation tanks, in particular to a fermentation tank structure. Background Fermentors are containers that provide a good environment for the operation of a particular biochemical process by microorganisms, and are commonly used for the production and preparation of fresh milk, sweet milk, yoghurt (pasteurized, reconstituted, fermented). For example, yogurt is taken as an example, when yogurt is produced, sterilized milk is pumped into a fermentation tank, and a particle starter (such as lactobacillus) is added, the starter breaks lactose in the milk into lactic acid, and simultaneously the temperature of the fermentation tank is adjusted to a range suitable for the growth of the lactobacillus and is kept for a period of time, so that the lactobacillus is fully fermented, an air distributor is one of main components in the fermentation tank, sterile air can be uniformly distributed into the fermentation tank, the microorganisms can be ensured to obtain sufficient oxygen for metabolic activity, fermentation efficiency is improved, growth of the microorganisms and accumulation of products are promoted, but a general air distributor does not have a clean structure, an air outlet is easily blocked by microorganisms, metabolites or other impurities in the use process, and the air distribution is uneven, so that the oxygen supply and fermentation effect of the microorganisms are affected. Disclosure of utility model The present utility model is directed to a fermenter structure for solving the problems set forth in the background art. In order to achieve the purpose, the fermentation tank structure comprises a tank body, a first rotating shaft, an air distributor and a discharge hole, wherein a feed inlet is formed in one end of the top of the tank body, a jacket is arranged on the outer side of the tank body, a temperature sensor is arranged at the top end of the inner portion of the tank body, the first rotating shaft is arranged at the central position of the inner portion of the tank body, second rotating shafts are arranged on two sides of the first rotating shaft, stirring pieces are uniformly distributed on the second rotating shaft, a driving motor is fixed at the central position of the top of the tank body, an output end of the driving motor is connected with the first rotating shaft, the air distributor is arranged at the bottom end of the inner portion of the tank body, an air outlet is uniformly distributed on the air distributor, an air inlet pipe is arranged at one end of the bottom of the tank body, the air inlet pipe is connected with the air distributor, a movable rod is arranged at the bottom end of the first rotating shaft through a connecting piece, a cleaning brush is uniformly distributed on the bottom surface of the movable rod, and the discharge hole is arranged at the central position of the bottom of the tank body.
