1 Adopted highly efficient heat exchange technology Miller board Jacket, steam onflow technology, to achieve a maximum thermal conductivity, energy saving. At the same time, adopted automatic temperature control technology, ensure the speed of heating, the time of warm keeping during mash and boiler. 2 Adopted the advanced lift type speed control system, through frequency conversion or self-control to stir. Ensure the mixture is frequency conversion, can maximize get all kinds of enzymes have a good biological activity transformation, ensure the quality of the beer and output at the headstream.
