work. Open the related valves and start the wort pump and pumped into the water, 290 kg
from bottom of lauter tun.

3）Feeding 55 ℃ (protein decomposition): first activate the filter tank mixing, malt powder into
lauter tun, after stirring uniform then stop it. starting time, for producing wheat beer, first
should put into barley malt and then stir them uniform and after that put wheat malt,
stir uniform; maintain the temperature of 55 ± 1 ℃, time 70 minutes;

warming up to 100 ℃, stop heating; open the related valves, ready to start wort pump and
ready for producing the mash water.

5）Producing mash water 66 ℃ (starch saccharification): Stirring the mash water of lauter tun,
while stirring pump into 100 ℃ hot water from the bottom of lauter tun. The temperature of
producing mash water kept as 66 ℃; After controled the temperature for black beer well, add
Coke-malt / empyreumatique malt and black malt powder, stirring evenly (3-5 minutes);
