Main beer brewing progress
Technology, equipment and raw materials are the three major factors that affect the quality and taste of beer. As a fermented beverage, beer brewing requires four main raw materials: barley malt, hops, yeast, and water. The beer brewing vessels serves the beer brewing process. The manufacture of beer brewing vessels must follow and meet the basic requirements of beer brewing technology.
Before understanding the beer brewing vessels, we must first understand the main brewing process and process of beer!
Beer brewing vessels contains: 1. Malt crushing system. 2. Mashing system. 3. Fermentation system. 4. Cooling system. 5. CIP cleaning system. 6. Control system, 7. Filling equipment, 8. Steam, air pressure and other auxiliary systems.
The output of beer brewing vessels depends on the type and size of mashing equipment, the batches of mashing per day; the size and number of fermentation tanks, and the fermentation cycle of beer.
Beer mashing system/brewhouse
The mashing system is the core of the whole set of equipment and is responsible for the process of making malt into wort. Namely: “mashing-lautering-boiling-whirlpool” four main process steps. These four functional steps are completed by several tanks. The hot water tank is auxiliary equipment.
Each function is realized by a single tank.The mashing system with four tanks is called :Four-vessel mashing system. The four functions are realized with three tanks called: Three-vessel mashing system. The simplest combination of mashing system with two tanks is called: Two-vessel mashing system
- Two-vessel:mash/lauter tank+boiling/whirlpool tank;
- Two-tank three-vessel mashing system: mash/lauter tank& whirlpool tank(mash/lauter tank is above the whirlpool tank) + boiling kettle);
- Three-vessel: mash tank+lauter tank+boiling/whirlpool tank;
- Four-vessel :mash tank+lauter tank+boiling tank+whirlpool tank
- Hot water tank is an optional

Three vessels beer mashing system
Main types of beer mashing system for small and medium-sized beer equipment:
Mashing system, It will need 7-8 hours from malt crushing to wort entering the fermentation tank. Hotels, bars and restaurants usually use 2 vessels+hot water tank 500L or 1000L beer mashing equipment,so it can mashing 1-2 batches per day. Taking into account factors such as labor and labor intensity, actually one batch a day.
The size of the beer mashing system and the highest batch capacity of mashing determine the maximum capacity of the equipment.
For example 2000L mashing system:
- two vessels can achieve a daily output of up to 4 tons.
- three vessels can achieve a daily output of up to 6 tons
- four vessels can achieve a daily output of up to 8 tons
Investment suggestion: The size and type of mashing system should be based on individual site, capacity requirements and investment budget. The larger the mashing system is, the higher the energy consumption is and the higher the investment cost is. However, the cost of later reconstruction is relatively high. So you can think about early saccharification in one step.
Fermentation system-beer brewing vessels
The fermentation system is mainly composed of fermentation tanks. The wort is fermented into beer in the fermentation tank. The fermentation tank has the function of cooling and heat preservation. From the inside to the outside, the fermentation tank has: inner wall, cooling jacket, insulation layer and outer wall. The control system controls the temperature of the beer in the fermentation tank according to the set temperature.The refrigerant of the refrigeration system is a cooling medium.
The quantity and size of fermentation tank
The volume of the mashing system and the fermentation system can be 1:1, 1:2…The volume of the fermentation tank is a multiple of mashing system. Simply speaking, the wort entering one fermentation tank should occur in 24 hours.
The fermentation cycle of Ale and wheat beer is 1-2 weeks, and the fermentation cycle of barley and lagers is 2-4 weeks. The average fermentation period is 12 days.
Take 500L fermenter as an example.
Namely: daily output (250L) = volume of fermentation tank (500L) × number of fermentation tanks (6) ÷ beer fermentation time (12 days)
Investment advice: Small beer equipment mainly refers to the self-brewed beer equipment and craft beer equipment used in hotels, bars and restaurant. Fermentation tanks are mainly 500L and 1000L. The number of fermentation tanks in the early stage can be 6pcs. It is relatively easy to expand production and add fermentation tanks later.
