China stainless steel fermentation vessel conical beer fermenter WEMAC Y066

The included angle of the cone bottom is generally 60-80 °, and there are also 90-110 °, 

but this is mostly used for large-capacity fermentation tanks. 

The height of the cone bottom of the fermentation tank is related to the included angle. 

The smaller the included angle is, the higher the cone bottom portion is. 

Generally, the height of the cone bottom of the tank accounts for about 1/4 of the total height, and should not exceed 1/3. 

The outer wall of the cone bottom should be provided with a cooling layer to cool the yeast deposited on the cone bottom. 

The bottom of the cone should also be installed with inlet and outlet pipes, valves, sight glasses, temperature and pressure sensing elements.

In addition, the diameter to height ratio of the tank is usually 1: 2 to 1: 4, and the total height is preferably not more than 16m, 

so as not to cause strong convection and affect the sedimentation of yeast and coagulum.

 Cans can be made of stainless steel or carbon steel. If carbon steel is used, 

the inner wall of the can must be coated with a non-toxic coating that does not affect the taste of beer. 

The working pressure of the fermentation tank can be determined according to the working nature of the tank. 

Generally, the working pressure of the fermentation tank is controlled between 0.2 and 0.3 MPa. 

The inner wall of the tank must be smooth and flat, the inner wall of the stainless steel tank must be polished, 

and the coating of the inner wall of the carbon steel tank must be uniform, with no uneven surface and no granular protrusions.

The fermentation broth in the tank produces a CO2 gradient (ie, a density gradient) due to the liquid height. 

Through cooling control, natural convection of the fermentation broth can be achieved, and the higher the tank, 

the stronger the convection. Due to the strong convection, the yeast's fermentation capacity is improved, 

the fermentation speed is accelerated, and the fermentation cycle is shortened.

The top of the tank is a round arch structure. The central opening is used to place a detachable large-diameter flange 

to install CO2 and CIP pipes and their connectors. The top of the tank is also equipped with sight glass, anti-vacuum valve, 

overpressure valve and pressure sensor The tank is equipped with a washing device inside, 

and a platform and a channel for tank top operation are also installed. 

The fermentation tank should be equipped with a high-pressure spray washing device, 

and the spray washing pressure should be controlled at 0.39 to 0.49 MPa or higher.
