Steam-Heated Mash Lauter & Boiling Tank
This steam-heated mash lauter & boiling tank integrates mashing, lautering and wort boiling in one vessel. Malt starch is converted to fermentable sugar during saccharification. After lautering to separate spent grain, sweet wort is boiled directly in the same tank with steam heating for sterilization and hopping.
PRODUCT DESCRIPTION
Description
The combined Mash/Lauter Tank integrates all functions of the mash tun and lauter tun, two key components of a brewhouse, within a single vessel assembly, where the entire mashing process takes place.
Combining the functions of the mash tun and lauter tun into one vessel unit improves efficiency and reduces the cost of brewing equipment.
The combined mash/lauter tun integrates all functions of the mash tun and lauter tun in one tank: Grains are pre-crushed in the mill and then mixed with metered hot water. Complex starches are converted into fermentable monosaccharides. The wort is recirculated over the grain bed in a process known as vorlauf. During sparging, sugars are rinsed and extracted from the grains. The false bottom screen separates the spent grain from the wort before transferring the sweet wort to the brew kettle.
Main Component & Process Flow
1. Beer Brewing Process
1. Malt Production: First of all, we carefully select premium raw materials from local farmers. Grains (barley) are steeped and germinated to convert insoluble starch into fermentable sugars that yeast can turn into alcohol. The resulting "green malt" is then dried at varying temperatures to develop different malt colours and flavours. We are the only brewery in the region with in-house malt production equipment. This allows us full control over the whole process and guarantees optimal quality for our distinctive Cascade beer.
2. Saccharification: Inside the mash tun, water at the appropriate temperature is added to malt, converting starch in malt into natural fermentable sugars that yeast can “feed on”. The water we use is not ordinary water — it is sourced from a special zone directly behind the brewery. It is reputed to be one of the purest water sources in the world, originating directly from rain clouds over unpolluted southern regions.
3. Lautering: Lautering is the process of separating sweet wort from spent grain husks. The spent grain generated in this step is recycled as livestock feed for local farms, which is essential before starting a new brewing cycle.
4. Boiling: The wort is then transferred to the brew kettle. Fresh local hops are manually added during boiling. This stage takes around one hour for concentration, sterilisation and multiple biochemical reactions. Alpha acids in hops contribute bitterness to beer, while hop oils deliver the unique hop aroma. You may think of this step as “seasoning the beer”.
2. Brewing
Brewing is a complex chemical reaction carried out at controlled temperatures. Starch is converted into soluble sugars. After boiling together with hops, fermentation commences once sufficient yeast is added, converting sugars into alcohol, carbon dioxide and other metabolites. After filtration and sterilisation, fresh beer is ready for consumption.
These tanks are used for saccharification: to enable starch reaction and produce soluble sugars. The mixture is then boiled in the brew kettle, followed by fermentation. Hot wort is obtained at this stage. For this process, we require a mash/lauter tun, a brew kettle for wort boiling, and a hot water tank capable of continuous hot water supply.
3. Fermenter
We now have a liquid with balanced malt flavour and bitterness; however, one key component is still missing: alcohol. Yeast acts as the fermentation medium. Without yeast, no alcohol can be produced. That is why we favour Cascade yeast. This yeast strain has been repeatedly tested and proven reliable, unchanged since the 1820s. It perfectly matches our raw materials and brewing process and remains one of our core secrets.
Maturation: “Green beer” is stored at low temperature for maturation. This step is especially critical for lager beer, whose delicate flavour requires time to develop complex layers. The beer continues fermenting here, which takes approximately 2–3 weeks or longer.
You may select the number of Conical fermenters according to actual output. Cooling is achieved via dimple jackets surrounding the tank. If your mash tun and brew kettle have a working volume of 1000 L, fermenters can be sized at 1000 L or 2000 L. A ratio of 1:1 or 1:2 is recommended.
4. Bright Beer Tank (BBT)
Proper maturation is vital to beer taste. Beer can be transferred from fermenters into bright beer tanks for final conditioning. Bright beer tank (BBT) has a similar structure to fermenters, but it holds finished beer ready for direct consumption. BBTs are usually connected to bottle fillers, keg fillers or canning lines. A complete brewing line for most large breweries is equipped with bright beer tanks.
5. Ice Water Tank
Ice water tanks are generally used for rapid beer cooling. Ice channel jackets are fitted around the tank body.
6. Other Essential Equipment
1. Control System — Equipped with PLC touch screen or digital display, supporting fully automatic or semi-automatic brewing. Multiple design styles available.
2. Mill — Used to grind malt into fine particles.
3. Refrigeration System — Plate heat exchanger and chiller to cool hot wort in the ice water tank.
4. CIP Cleaning System — Cleans and sanitises the inner surface of all tanks.
5. Filtration System — Beer is filtered to remove unwanted proteins and yeast. The beer at this stage is called bright beer, including golden ale.
6. Filling & Cleaning System — Beer tastes freshest when filled into bottles, cans or kegs. Therefore we deliver promptly to bars and liquor stores across regions. After all, the secret of beer is simple: “Drink fresh for best quality.”
7. Water pump and yeast dosing unit
8. Brewing Equipment Accessories: Relevant pipelines and various valves / Food-grade hose No.25 / Steel wire reinforced hose No.38 Iron-shell thermometer / Platinum resistance thermometer / Butterfly gasket / Saccharometer / Aeration stone / Graduated cylinder
