HOT LIQUOR TANK (HLT) is a large, insulated tank that holds hot water for various purposes in the brewing process. It is used to heat water to specific temperatures for mixing with malt to form the mash, which is the step of converting starches into sugars. It is also used to provide hot water for sparging, which is the process of rinsing the sugar from the grains. Water is heated using steam but water can also be heated using a plate heat exchanger
where hot wort transfers temperature to the water. Hot liquor tank (HLT) can improve the efficiency, quality, and consistency of the brewing process, as it allows for precise control of water temperature and volume. Hot liquor tank (HLT) is an essential part of the brewing system for professional and home brewers alike, as it prepares the water that becomes the beer.
