Beer fermentation and fermentation tank

The art and science of brewing beer involve a fascinating process known as fermentation. This transformative stage is where the magic happens, converting sugars into alcohol and creating the distinctive flavors and aromas that beer enthusiasts savor.

The brewing process of craft beer basically has two important core steps: one is malt saccharification, and the other is wort fermentation. Among them, the wort fermentation process is mainly completed by fermentation tanks. For beer wort fermentation, beer fermentation tanks, configuration of fermentation tanks, fermentation processes, fermentation control and other related information, please continue to look down.

1. The basic principles of craft beer fermentation and fermentation tanks

In the beer brewing process, the malt passes through the saccharification system to prepare the wort, which is cooled, enters the fermentation tank, adds the brewer's yeast, and starts the fermentation. The traditional process is divided into pre-fermentation and post-fermentation, which are carried out in different fermentation tanks. The current popular method is to carry out one fermentation in one tank. The pre-fermentation mainly uses yeast to convert the maltose in the wort into alcohol (that is, the anaerobic respiration of yeast), and the post-fermentation mainly produces some flavor substances, removes the peculiar smell in the beer, and promotes the maturation of the beer.

2.Characteristics of beer fermentation and fermentation tanks

1. It should have a tight structure.

2. Good liquid mixing characteristics.

3. Good heat transfer rate of mass transfer phase.

4. It has matching and reliable detection and control instruments.

5. High reliability of fermentation process operation.

3. Configuration instructions of beer fermentation tank

1. The volume of beer fermentation tank is determined according to the customer's requirements; it is generally divided into two parameters, effective volume and total volume, because beer fermentation requires a certain amount of fermentation tank space, and the total volume is generally 1.2-1.3 times the effective volume.

2. The overall dimensions of beer fermentation tanks are generally designed flexibly according to the customer's site, but the basic height-to-diameter ratio is not less than 1.

3. The material of beer fermentation tank is mainly food-grade SUS304 stainless steel. SUS316L can also be used if the customer requires it, but the cost is much higher.

4. The polishing accuracy of the inner wall of the beer fermentation tank is not more than 0.6um.

5. The beer fermentation tank needs heat preservation. Generally, polyurethane is used as the heat preservation material.

6. Beer fermentation tanks are generally designed with lower cones, and they are usually designed with 60° and 72° taper pressure resistance.

7. Cooling method of beer fermentation tank: mainly use stainless steel Maitreya plate or hose jacket to cool down. The cooling medium is generally cooled by ice water circulating at minus 7 degrees.

8. Cleaning of beer fermentation tank: Mainly equipped with cleaning device, cyclic cleaning with water, alkaline water or disinfectant.

9. The beer fermentation tank is equipped with a top pressure manhole or a waist pressure manhole, which is convenient for observation or manual cleaning in the tank.

10. The temperature control of the beer fermentation tank mainly adopts PT100 temperature probe detection, and the solenoid valve controls the flow of ice water for automatic control.

11. The pressure control of beer fermentation tank mainly adopts mechanical pressure regulating valve to automatically control, and the pressure gauge shows.

12. Other pipe fittings and valves, such as sampling valve, butterfly valve, ice water valve, hops, etc., shall be prepared according to process requirements.

4.Description of the role of beer fermentation tank accessories

1. Wine receiving valve: If the wine is sold directly in the fermentation tank, it is recommended to configure a wine receiving valve, which can facilitate wine receiving.

2. Refrigeration system: It can accurately control the beer fermentation temperature, reduce the error of the fermentation temperature, and ensure the quality of beer brewing.

3. Manhole of the fermentation tank: It can add hops, and it is also convenient for everyone to observe the wine level, and it is also convenient for people to enter the tank for manual cleaning of the inside of the tank.

4. Pressure gauge: It is mainly used to display the pressure data of the fermentation tank, so that everyone can observe the pressure in the tank.

5. Fermentation temperature controller: used to adjust the beer fermentation temperature to ensure the stability of the fermentation temperature during the beer fermentation process.

6. Safety valve: The safety guarantee of the beer fermentation process can automatically discharge the pressure to prevent the air pressure from being too high due to operator errors and safety accidents.

7. Sampling valve: It is mainly used for sampling and testing of fermentation liquid during beer fermentation to prevent bacteria contamination during fermentation due to sampling.

8. Level gauge: If it is convenient to observe, you can configure a level gauge to know the quantity of beer in the fermentation tank at any time.

5. Fermentation process of beer fermentation tank

1. Beer fermentation temperature control: Controlling different fermentation temperatures has its own advantages and disadvantages. Using low-temperature fermentation, yeast produces fewer by-products during the fermentation process, which makes beer taste better and foams in good condition, but the fermentation time is long; Using high-temperature fermentation, the fermentation speed of yeast is faster, the fermentation time is short, and the utilization rate of the equipment is high, but there are more by-products and the beer taste is poor.

2. Control of beer concentration: The change of wort concentration is affected by fermentation temperature and fermentation time. If the fermentation is vigorous and the sugar reduction rate is fast, the fermentation temperature can be appropriately lowered and the maximum temperature retention time can be shortened; on the contrary, the fermentation temperature should be appropriately increased or the maximum temperature retention time should be extended.

3. The control of beer fermentation time: The fermentation time mainly depends on the change of fermentation temperature. If the fermentation temperature is high, the fermentation time will be short; if the fermentation temperature is low, the fermentation time will be long.

There are many types of fermentation tanks, as long as they are used in the fermentation industry, because of different uses, their requirements for fermentation tanks are also different. Beer fermentation tanks are also different according to the brewing of different beers. The above mentioned are the general contents of beer fermentation tanks for reference.
