The mashing system is divided into three parts, the first is the Mash+Lauter tank, the second is the Kettle/Whirlpool Tank, and the other is the HLT . The malt enters the Mash+Lauter tank from the milling system, and the wort is filtered out and enters the Kettle/Whirlpool Tank. Then enter the fermenter for fermentation. The HLT provides adequate hot water to this mashing system.
