Hot Liquid Tank HLT
Also known as a hot liquid tank, it is a tank/container that heats the blow and sprays water to the desired temperature. HLT is essentially a water heater, and the size of HLT should be proportional to the size of your brew. For example, you'd better use 10 gallon HLT or 5 gallon batches or 15 gallon HLT for 10 gallon batches. Large-scale operations use industrial-grade HLT to heat large amounts of water.
Hot wine tanks are usually stainless steel, with capacities ranging from 10 to 1000 gallons depending on the size. Some breweries may use a hot wine tank/malt filter tank combination container, while other breweries may invest in two designated containers to speed up the process.
The mash barrel/filter barrel is a container used to mash grains and hot water to produce wort (unfermented beer). A masher is a container in which saccharification takes place and the wort (unfermented beer) is separated from the grain. Most home brewers use 10 or 15 gallon mash filter barrels to heat their spray water.
Depending on the scale of production, beer bars and breweries may use mash filter barrels with a capacity of 100 gallons or more. Most mash and filter barrel containers are stainless steel.
Brewing pot and whirlpool
Brewing pot, also called boiler, boiling pot or copper pot (if made of copper), is a container that boils mash to a specific gravity and adds hops and other flavoring agents. The boiling process allows various chemical reactions to occur, including sterilizing the wort, releasing the hop flavor, concentrating the wort, releasing bitterness and aroma compounds through isomerization, and stopping the enzymatic process.
For smaller operations, home brewers often improvise by boiling the mash in a saccharification vessel. However, in addition to the vortex that allows the wort to settle, more sophisticated beer bars and breweries also specify brewing pots for the boiling process. Regardless of your preference, cleanliness and hygiene are essential for the brewing kettle.
Brewing pots are usually made of stainless steel or copper (depending on the brand and manufacturer) because these materials are easier to clean. The price of brewing pots depends on their size, manufacturer (made in the United States and made in Germany or China) and quantity. Some brewing pots are sold in sets, providing multiple boilers for simultaneous brewing. The size of the brewing pot ranges from 50 liters to 1000 liters (or larger), usually measured by BBL production capacity, ranging from 1-7 BBL to more than 50 BBL.
Based on your estimated production capacity and the heating process you plan to use (electricity and steam, direct and indirect fire), you should talk to your supplier to determine which type and size of brewing kettle is best for your craft brewery.
The whirlpool causes the boiled wort, all soluble proteins and plant matter in the hops to settle and collect in the center of the kettle. By collecting in the center of the whirlpool, it is easier to remove unwanted residue from the wort. The clear wort is then pumped through the heat exchanger and into the fermenter. Many brewing pots are designed to be used as a vortex after the boiling process has occurred, and the wort may settle in the same container.
The heat exchanger, also called the wort cooler, allows you to cool the wort from boiling to yeast temperature in time. Immersion coolers, plate and counterflow wort coolers will exchange (or reduce) heat to help increase the overall transparency of the beer and reduce the chance of odor and contamination. In order to inoculate yeast and start the fermentation process, the wort must first be cooled to a temperature suitable for fermentation.
Modern breweries usually use plate heat exchangers, which contain ridge plates that form two independent paths. One path is for the wort, and the other path is for the cooling medium, usually water. Plate heat exchangers are usually made of stainless steel and brazed with copper. Depending on the brewing capacity, you will need a plate heat exchanger of the right size to properly cool the wort when it is transferred to the fermenter.
Fermentation tank is a kind of aging container, the yeast is injected into the wort, effectively turning it into beer. The wort is pumped through the heat exchanger into this container, and then added to the previously cast yeast, where it can begin to ferment. Some breweries designate aging containers to transfer the beer to the aging process.
The number of fermentation tanks required depends on your brewing output. Generally speaking, the more fermenters available, the more beer that can be brewed, fermented and aged at the same time. Similar to other containers, fermentation tanks are usually stainless steel, ranging in size from 5 BBL to 6,000 BBL. Depending on your floor layout and output, the storage tank may be open or closed, horizontal with manholes, or vertical with tapered bottoms. Unitank fermenters can be used for fermentation and storage. Today, most craft breweries use cylindrical fermentation tanks, which are designed with a conical bottom and a cylindrical top.
