The steps to clean the stainless steel beer fermentation tank are as follows:

1. First, brush off the residual distiller’s grains and lees in the beer fermentation tank for subsequent cleaning.

2. Pour an appropriate amount of cleaning agent into the interior of the beer fermentation tank and let it fully soak. The selection of cleaning agents should be based on the materials and usage of the beer fermentation tank.

3. Use a soft brush or sponge to evenly apply the cleaning agent to all corners of the beer fermentation tank, allowing it to fully penetrate.

4. Thoroughly rinse the interior of the beer fermentation tank with clean water to ensure that the cleaning agent and residual dirt are removed.

5. Use a clean cloth or air gun to dry or blow dry the interior of the beer fermentation tank.

It should be noted that cleaning agents containing acidic and chloride ions should not be used during the cleaning process, as these substances can cause corrosion to stainless steel materials, affecting the quality of beer and the service life of fermentation tanks.

The stainless steel beer fermentation tank is an indispensable equipment in the beer production process, and the thoroughness of the cleaning process can directly affect the quality of beer and the service life of the fermentation tank. Therefore, it is crucial to develop a reasonable cleaning plan and use cleaning agents and methods correctly to ensure the quality and stability of beer production.
