By deriving advanced design and fabrication technology from both at home and abroad, and combining the advantages of technological reformation and patented technology of our company, the special manufactured “four-kettle & three-tank” equipment made by us has the equal strength of turnkey project. Mash cooper and mash tun adopt hanging reducer transmission and frequency control. Agitation adopts advanced blade, which can evenly mix the mash. It will not produce shear force, as a result, the mash can realize the conversion sufficiently. Jacket heating part of the mash cooper and mash tun adopts cellular board, on the basis of incremental heating, the mash will not coking. As a result, we can save time and steam, drain off the water fluently in heating process.
