A commercial beer brewing system works by controlling a sequence of physical and biological processes that convert malt, water, hops and yeast into finished beer.<\/p>\n
What happens first?<\/p>\n
The process begins with malt preparation.<\/p>\n
Malt is milled to expose the starch inside the grain while retaining enough husk structure for efficient lautering.<\/p>\n
The milled malt enters the mash tun.<\/p>\n
What happens during mashing?<\/p>\n
During mashing, malt is mixed with hot brewing liquor.<\/p>\n
Enzymes convert starch into fermentable sugars.<\/p>\n
Temperature control is important because different temperature ranges influence enzyme activity and wort composition.<\/p>\n
How does lautering work?<\/p>\n
After mashing, the liquid wort must be separated from the spent grain.<\/p>\n
The lauter system uses the grain bed as a filtration medium.<\/p>\n
The resulting wort is transferred to the brew kettle.<\/p>\n
Why is wort boiled?<\/p>\n
Boiling performs several functions.<\/p>\n
It helps sterilize the wort, concentrates the wort and enables hop utilization.<\/p>\n
Boiling duration and hop additions depend on the beer recipe.<\/p>\n
What happens in the whirlpool?<\/p>\n
After boiling, the wort can be transferred to a whirlpool vessel.<\/p>\n
Controlled flow creates a vortex that helps separate trub and hop material from the wort.<\/p>\n
The clarified wort is then sent through a heat exchanger.<\/p>\n
How is wort cooled?<\/p>\n
A plate heat exchanger is commonly used to rapidly cool wort to the appropriate fermentation temperature.<\/p>\n
Cold water and\/or glycol systems can be used depending on the brewery design.<\/p>\n
What happens after cooling?<\/p>\n
The cooled wort enters a fermentation tank.<\/p>\n
Yeast is added, and fermentation begins.<\/p>\n
Temperature and pressure can be controlled according to the beer style and fermentation process.<\/p>\n
Where does the finished beer go?<\/p>\n
After fermentation and conditioning, beer may be transferred to a bright beer tank.<\/p>\n
It can then be carbonated and sent to:<\/p>\n
Kegs
\nBottles
\nCans
\nOther approved packaging formats
\nWhat controls the process?<\/p>\n
Commercial systems may use manual, semi-automatic or fully automated controls.<\/p>\n
Sensors can monitor temperature, pressure, flow and tank conditions.<\/p>\n
PLC and HMI systems can coordinate pumps, valves and heating or cooling systems.<\/p>\n
