(1) Use 4-section speed for mixing; time and speed can be adjusted individually and the vacuums are kept inside of mixer. Also, to have the best flour strength by fully mixing when the air in the flour is removed and water is permeated into the center of flour due to the blades with a special design on dual spindle multiple blades. (2) Multi-nozzle high pressure atomization water adding is used as the water delivery method; the flour is unable to become the massive dough after mixing the flour when the flour absorbs the water fully and evenly in a short time. (3) The functions, which are designed for this machine, are variable frequency speed regulation, PLC programmable controller, human machine interface operation, abnormal failure self-diagnosis and simple operation. It can be operated either manually or automatically according to customers’ requirements. (4) Interlayer design is used for the whole machine body; either the hot water (for frigid zone) or icy water (for hot zone) can be passed through the machine; the best mixing temperature is kept at 25℃～30℃. (5) All parts, which contact flour, are made of SUS 304 material, mixing blades are treated with SUS304 precision casting surface polishing process.
