They are a kind of equipment for mechanical agitation and fermentation of materials. In the production, the cleaning of the fermenter is a big question, and the cleaning in the brewing and beverage industry usually takes a lot of automation.
The cleaning methods commonly used for cooling fermenters can be divided into physical cleaning and chemical cleaning. Physical cleaning refers to cleaning and pressure generated by cleaning equipment. Chemical cleaning refers to cleaning liquid cleaning. The chemical cleaning of the fermenter can be divided into cold cleaning and hot cleaning according to the cleaning temperature. Cold cleaning refers to cleaning at room temperature, and hot cleaning refers to heating cleaning. According to the type of cleaning agent, it can be divided into acidic cleaning and alkaline cleaning.
The cold cleaning method is usually used on large fermenters. The cleaning of large fermenter equipment is difficult. Although the hot cleaning method can save time and the use of cleaning fluid, large-scale fermenters are often used for cold cleaning method. The advantage of the hot cleaning method is that it can save the cleaning time and the use of the cleaning liquid. The residual dirt of the fermenter body at a higher temperature is also relatively clean and clean, and the hot cleaning method is usually applied to a small fermenter body.
