Why do brewery equipment need larger capacity hot water tanks?

Brewing beer involves using hot water, usually at a specific temperature. “Flushing” is used to soak the grains at a specific temperature to release the sugars. The sugar is then rinsed away using a “squirt” of water. This is the stage where a hot water tank (HLT) is used. This is the source of the hot water that becomes beer. The hot water tank is an important part of ensuring stable beer quality. In this article, we’ll take a closer look at commercial breweries’ hot water tanks and why they are an important part of consistent quality beer.

What is a hot water tank?

A hot water tank is a large insulated container that stores and heats water to a specific temperature. These tanks are usually made of stainless steel and are available in a variety of sizes, depending on the needs of the brewery. Water tanks are usually equipped with heating elements and temperature controllers to ensure that the water is heated to the required temperature and maintained at that temperature for as long as required.
HLT heating capacity:
  • Steam heating
  • Electric heating
  • Direct heating
  • External steam heat exchange
Specifications of HLT
  • Liquid container with standard 10% headspace
  • SUS304 material
  • Inner shell: SUS304, thickness 3mm
  • Shell: SUS304, thickness 2mm
  • 80mm rock wool insulation layer
  • Single/double/three-zone corrugated steam jacket
  • TIG welding structure
  • CIP cleaning ball

What does a hot water tank do?

A hot water tank is used to maintain a specific temperature while soaking the grains. This is usually done by using heat exchange coils placed in the tank. In the brewing world, it’s known as a heat exchange recirculating mash system.
Mash thickness is considered a very important factor in the brewing world and I see many brewers paying a lot of attention to this.
Brewing beer in a consistent manner should always involve a procedure that can be repeated. Several factors should be considered throughout the brewing process, as they play an important role in the taste and quality of the beer. These factors include the amount and temperature of the grain, the amount and temperature of the impingement water, the air temperature, the temperature and size of the container used, and finally the degree of temperature loss due to poor mixing and insulation.

Does a brewery need a hot water tank?

If the brewer brews once a day, budget considerations may make it ok without a hot water tank. We can then recycle the hot water into the saccharification/filtration tank (the tank needs to be cleaned in advance). Hot water is available for use the next day. It will be cooler and colder after one night, but at least we saved water.

If the brewer brews twice a day, to save mashing time and turn cans, it is best to have a hot liquid tank to circulate hot water to start the second mashing of the day. Hot water can also be used for spraying.

Micet’s hot liquid tanks come standard with the same capacity as the brewery. Additionally, most brewmasters now prefer larger capacity hydrothermal tanks for breweries. It can usually be 1.5-2 times larger than a brewery. Using a hot water tank is a good thing in the long run.

Why do brewery equipment need larger capacity hot water tanks?

Larger capacity hot water tanks (HLTs) in breweries can provide a variety of advantages, depending on the size of your brewing operation and your specific brewing process. HLT is a key component in the brewing process, used to heat and store hot water for various purposes, for mashing and sparging.

  1. Batch size: If you are brewing larger quantities of beer, you need more hot water to mash and squirt the grains . A larger HLT ensures you have enough hot water to cover the entire batch.
  2. Mashing and sparging efficiency: A larger HLT helps maintain consistent temperatures during mashing and sparging, which is crucial for obtaining high-quality wort. It ensures you have enough hot water to reach your target mashing temperature and volume, converting starch into sugar more .
  3. Versatility: The water-to-grain ratio can be adjusted and different mash configurations achieved to create a wider range of beer styles.
  4. Consistency: With a larger HLT, the same brewing process and recipes can be repeated batch-to-batch, resulting in consistent beer quality.
  5. Time efficiency: Larger HLT can save time during the brewing process. Water can be heated and held in the HLT while other brewing tasks are performed, reducing downtime and brewing time.
  6. Energy efficiency: Reduces the need to reheat water during brewing. By heating large amounts of water and maintaining it at a constant temperature, you reduce heat loss and save energy costs.
  7. Brewery expansion: If the brewery capacity is expected to be expanded in the future, investing in a larger HLT as early as possible can save you the trouble of upgrading later.
  8. Water treatment: Some breweries must treated water for brewing. Larger HLTs can store larger volumes of process water, ensuring adequate water volume for each batch.
  9. Cut Thermal Shock: A larger HLT helps prevent rapid temperature swings during the brewing process. Rapid temperature changes can affect enzymes and the quality of your beer.

Why is a hot water tank important to a brewery?

  • Stable quality: To produce beer of stable quality, the brewing process must be controlled. This includes the temperature of the hot water used in various stages of brewing. With a hot water tank, a brewery can ensure that the water is heated to the right temperature and maintained at that temperature throughout the brewing process.
  • Efficiency: Hot water tanks enable breweries to heat large amounts of water . By heating and storing water in tanks, breweries can save the time and energy needed to heat water on demand.
  • Safety: Brewing beer requires high temperatures, which may be dangerous if not managed . Hot water tanks are designed to be safe to use and have built-in safety features to prevent overheating or other hazards.
  • Increased Capacity: With a hot water tank, breweries can increase capacity and brew larger batches of beer. This is especially important for breweries looking to expand operations and increase production.

Choosing the right hydrothermal tank for your brewery

Choosing a hot liquid tank is also an important decision. The following factors can be used for your reference:

  • Size: The size of your hydrothermal tank you need depends on the size of your brewery and the amount of beer you produce.
  • Insulation: The hydrothermal tank should be well insulated to prevent heat loss and ensure the water remains at the desired temperature. Look for tanks with high-quality insulation and construction. Micet has extensive experience here and can help you choose the right hydrothermal tank.
  • Heating Element: Consider the type of heating element you need for your hot water tank. Options include electric, gas, and steam-powered heating elements.
  • Temperature Control: Make sure the hot water tank you choose has a temperature controller so you can set and maintain your desired water temperature.
  • Durability: A hot water tank is an investment in your brewery, so choose one that is durable. Look for a tank that is made of high-quality materials, such as stainless steel, and has a sturdy construction.
  • Maintenance: Finally, consider the maintenance requirements of the hot water tank you choose. Look for a tank that is easy to clean and maintain and has accessible components that can be serviced as needed.
