Customized Hot Water Tank Store Tank for Liqour Hot Liquor Tank with Heating
The hot liquor tank is a vessel used in beer brewing to store and heat water for mashing and sparging. It is also known as a hot water tank or HLT.
PRODUCT DESCRIPTION
Description
As the name suggests, a Hot Liquor Tank is a vessel used to heat and store the hot water used in brewing. This water is referred to as "liquor" in brewing terminology.
Its primary functions are:
1. Providing hot water for mashing:
Hot water at a specific temperature is mixed with crushed malt during the mashing process to convert the grain's starches into fermentable sugars.
2. Providing hot water for sparging:
After mashing, hot water is used to rinse the grain bed(sparging) to extract as much of the sugars as possible.
Core design points:
1. Heating Method:
-Electric heating element
-Steam heating jacket
-Direct gas fire heating
2. Insulation:
Must maintain water temperacture for extended periods to save energy and ensure stable mashing and sparging temperatures.
3. Temperature Control:
Must be equipped with a high-precision temperature probe and controller.
4. Material:
Food-grade 304 or 316 Stainless steel is the standard.
Corrosion-resistant, easy to clean, does not affect water quality.
5. Capacity:
Capacity should at least match the Mash Tun, often slightly larger, as it needs to hold both the mashing water and sparging water. (e.g., for a 500L batch, HLT capacity might be 1000L).
6. Sight Glass/Level Gauge:
Allows visual monitoring of water volume for precise control during mashing and sparging.
The Hot Liquor Tank is the "logistics commander" ensuring precise temperature control during the beer brewing precess. An efficient, well-insulated HLT with accurate temperature control significantly improves mashing efficiency,
leading to more consistent and higher-quality beer.
Aelt Professional Brewing Control System: push buttons control panel/PLC control panel (semi-automatic control/full-automatic control )
We also provides all auxiliary equipment for breweries, such as keg washing machines, bottle filler/cappers, Flash Pasteurizer, steam boiler, yeast brinks, hopgun, hops cannon, etc.
