Beer is a fermented liquor with carbon dioxide, fizz and low alcohol  concentration, which is made of malt and water as the main raw materials, hops (including hop products), and fermented by yeast.

Brewing Process

The brewing process of beer can be roughly divided into wort manufacturing, wort processing, wort fermentation (also known as beer fermentation), beer filtration, and other production processes.

Wort Making

The production process of wort production includes the crushing process of raw and excipients for beer production – barley malt and rice (used domestic excipients); gelatinization and liquefaction process of excipients, saccharification process of raw materials and excipients, mash filtration and wort washing process, wort boiling process And the hop addition process, the separation of the hot coagulation of the boiling wort – swirling process; the wort processing and production process, including the wort cooling process; the wort oxygenation process.

Wort Processing

THis wort production follows the batch production method. The equipment for making wort is composed of pots and tanks, supplemented by pumps, pipes, and heaters. The combination of pot and tank, it can be roughly divided into:

  • The combination of the two vessels, can brew 2-3 batches per day;

  • The combination of the three vessels,(mash tun, lauter tun, kettle/whirlpool tank; mash/brew kettle, lauter tun, whirlpool tank) can brew 3-5 batches per day;

  • The combination of the four vessels can brew 5-6 batches per day;

  • The combination of the four vessels & staging slot can brew 6-7 batches per day;


Wort Processing

In the early stage of the beer fermentation process, aerobic respiration, yeast cell proliferation, anaerobic fermentation at a later stage,By using the nutrients in the wort to generate alcohol, fusel oil, organic acids, etc. Traditional fermentation is generally divided into two stages: main fermentation and post-fermentation. To shorten the fermentation cycle and improve the use rate of the equipment, the cone-type fermentation tank one-pot fermentation method is now used. which is currently the best choice for beer brewing production. The investment is low, the fermentation cold consumption is low, the operation is simple, and it is suitable for brewing different types of beer, and the quality of the brewed beer is also the best.

Beer Filtration

Beer filtration can use various forms of diatomite filter (plate and frame type, candle type (commonly used), disc type). It can effectively remove suspended solids, improve the appearance of beer; improve the colloidal stability of beer; improve the stability of biology; small wine loss, less carbon dioxide loss; not easy to pollute, not absorb oxygen,does not affect the flavor of the beer.

Beer Filling

The basic principles of beer filling are to cut the contact of oxygen; cut the loss of carbon dioxide; strict aseptic operation. The filling forms are bottled (glass, polyester plastic), canned (canned), and barreled. The filling method is divided into pressure filling method, vacuum filling carbon dioxide filling method, secondary vacuum filling and so on.

Refrigeration equipment, steam production equipment, compressed air production equipment, etc. required for beer brewing production have a large choice according to the production scale and investment scale. The initial investment scale is large, energy-saving production equipment is configured, and the later production and operation costs are low; the initial investment scale is small, the configuration of cheap production equipment, and the later production and operation costs are high. This requires the designer, according to the production scale, to calculate the investment recovery period of energy-saving production equipment, consider, select the configuration design scheme with high cost performance of the equipment, and select and design the auxiliary equipment.
