[0002] Fermented bean curd is a traditional food with rich nutrition and unique flavor. Its production process needs to go through a fermentation process. During the fermentation process, appropriate internal pressure is crucial to the quality and fermentation effect of the fermented bean curd. When fermenting, it is usually carried out in the corresponding fermented bean curd fermentation equipment. This type of fermented bean curd fermentation equipment is generally equipped with a pressure gauge and a pressure relief valve.
