Haichuan Brand Mash Tun is stainless steel vertical, double-walled, insulated vessel with dished head insulated with polyurethane in the top portion and rock-wool in the steam-heating sections area.
Mash Tun has a 15° conical floor with inverted center for agitator seal. A bottom mounted mash agitator system incorporates offset paddles to ensure thorough mixing of the mash. Paddles are driven by geardrive-motor and are controlled by an AC variable frequency drive.
Mash hydration unit, into which enters an auger transporting malt from grist case, is mounted to the tank head and provides complete hydration of grain.

Vessel heating is provided by two independently controlled steam-heating section with heating capacity 1°C per minute and steam pressure of 4 bar at 150°C temperature. Inlet of steam into heating-sections is controlled from central control panel by electrically operated solenoid valves, depending on temperature and speed of heating. Temperature in the vessel is controlled by thermo-sensor installed in the lower cylindrical part and evaluated by the control system.

A 500 mm round man-way-cover and vent-chimney are placed on the top of dished head.
Tank is equipped in the dished-head with a rotating mechanical sprayball for thorough washing and sanitation.

Adopted high 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.

Adopted the advanced lift type speed control system, through frequency or self-control to stir. Ensure the mixture is frequently conversion, can maximize the biological activity transformation, ensure the quality of the beer and output .at the headstream.
