How To Improve The Brewhouse Utilization

Improving brewhouse utilization just means faster brewhouse turnaround. Attempt to reduce the time spent in each tank, such as brew kettles, lauter tanks, etc.

(1) Minimize brew kettle holding time
In general, the brewing kettle is the one with the longest holding time, which is almost equal to the holding time of the Lauter tank plus the boiling time of the wort, even though the effective working time does not exceed 90-120 minutes. Therefore, it is very important to control the process conditions. In addition, a wort storage tank with preheating function can be added after saccharification. It can be used to save the next batch of wort when the reactor is busy boiling, so that the holding time of the reactor can be shortened to 160-190 minutes, with nearly 7.5-9 turnarounds per day.

(2) Minimizing wort drainage time
Considering that wort excretion may be affected by several factors, the total time may reach 4-5 hours if the wort cannot be excreted smoothly. If the holding time of the distiller does not exceed 180 minutes, it can be turned over 8 times a day. In addition, with the help of a wort filter, fermentation takes only 120 minutes, which will greatly improve the daily feeding time.

(3) Speed up the turnover of rice paste pot and mash pot
Increase the feed temperature of the auxiliaries at around 65-70°C and use thermostatic bacterial amylase instead of malt liquor. The mash can be heated directly at high temperature, saving heating time.
Adopting one-time decoction, rapid saccharification or infusion saccharification can save some time of heating up or boiling. Of course, the quality of malt will be better.
Reduce the amount of auxiliary ingredients appropriately or add some protease or dextranase to make the resting temperature of protein lower. This will minimize the resting time and the total saccharification time of the protein.

Then, it is possible to make the saccharification cell turn over 8-9 times per day.
