Description

Food fermentation tank Technical Field The utility model belongs to the technical field of food fermentation, and particularly relates to a food fermentation tank. Background Food fermenters are biochemical reaction equipment specially used for microbial fermentation, and by providing proper temperature, humidity, ventilation and stirring conditions, strains are propagated in a liquid culture medium in a large quantity and required metabolites are secreted. Food fermentation tanks are generally composed of a tank body, a stirring system, a ventilation system, a temperature control system, a control system and the like. The tank body is generally made of stainless steel materials, and has good corrosion resistance and sealing performance so as to ensure the sterile environment in the fermentation process. The stirring system enables the culture medium and the strain to be fully mixed through rotation of the stirring paddles, and fermentation efficiency is improved. The ventilation system is responsible for introducing sterile air into the tank so as to meet the requirement of the strain on oxygen. The temperature control system maintains a suitable temperature range within the tank by heating or cooling the medium. In the process of food fermentation, a large amount of gases such as carbon dioxide and ammonia gas can be generated, the gas increases the air pressure in the fermentation tank, the tank body is easy to damage, the high-pressure environment is not suitable for survival of strains, the food fermentation is easy to fail, and the gas in the fermentation tank has pungent smell when being discharged, pollutes the atmosphere environment and also causes harm to the health of staff. Disclosure of utility model According to the defects in the prior art, the technical problem to be solved by the utility model is to provide the food fermentation tank, which is used for discharging gas in the tank body and purifying peculiar smell of the gas at the same time so as to avoid polluting the atmospheric environment. The food fermentation tank comprises a tank body, the mounting hole has been seted up at tank body top, is provided with the fixed section of thick bamboo of opening downwardly in the mounting hole, is provided with in the fixed section of thick bamboo and is used for carrying out the exhaust subassembly of discharging to the internal gas of tank, fixed section of thick bamboo lateral wall is provided with the purifying drum, purifying drum and fixed section of thick bamboo are connected through the connecting pipe and communicate with each other, are provided with the HEPA plywood that is arranged in the purifying drum and is used for dispelling the pollutant particle in the gas, HEPA plywood lateral wall is provided with the activated carbon sheet that is arranged in adsorbing the peculiar smell in the gas, the exhaust hole has been seted up to purifying drum lateral wall, exhaust hole department is provided with the blast pipe, installs the valve on the blast pipe.
