Nowadays, most of the beer brewery equipment are made by stainless steel. As we know the smoothness inside of the brewery equipment tanks is very important for beer brewing, which mostly shows by Roughness.
Especially the bottom of the tank and discharge arm, the roughness must be smaller, in case the bacteria survived. Generally the roughness of the welding line must to reach 0.4-0.5um after polishing.
The diameter of the yeast at about 6-10um, it cannot hide inside of the material. But for bacteria, its size is only 0.7-4um, it may survived inside of the welding line if we cannot make it smoothly, then the beer may be polluted.
So the polishing is very important during the manufacturing of beer brewery equipment. We Tiantai generally adopted acid pickling and passivation which will remove the welding oxygen firstly and then form a protection layer on the tank surface. The accuracy of the tank will reach 0.2-0.4um.
