Alcohol fermentation equipment made of steel plate alcohol fermenter made of steel plate, steel plate thickness varies depending on the volume of the fermenter, generally 4-8 mm thick steel plate made of cylindrical tank body, tank body diameter and height ratio of 1:1.1; cover and bottom of the conical dish; tank cooling snake tube, snake tube number generally take each cubic meter of fermentation mash with not less than 0.25 square meters of cooling area. Snake tube can be divided into two groups of upper and lower installation, and be fixed. There are also used in the top of the tank with a shower pipe or shower enclosure so that the water along the wall of the tank to flow down, to achieve the purpose of cooling the fermentation mash. For larger fermentation tanks, these two cooling forms can be used at the same time. Alcohol plant located in the south, because of the high temperature, it should strengthen the cooling measures. Some factories set up bubble blowers at the bottom of the fermenter to stir the mash and make the fermentation uniform. The top of the tank is equipped with CO2 discharge pipe and heating steam pipe, mash input pipe. However, the piping setup should be simplified as much as possible, so that one pipe can be used for multiple purposes, which plays an important role in reducing the dead space of the pipe and preventing contamination by stray bacteria. The top and side of the large fermenter should also have a manhole, so as to facilitate cleaning.
Cement alcohol fermentation tank is made of reinforced cement, the shape can be divided into two kinds of round or square. Some made of sealed, can also be made of open type. Because the cement fermentation tank is easy to corrode, escape wine and sterilization is not complete and other shortcomings, so the general plant is not used.
