The foam of draft beer is determined by temperature, pressure, residual sugar, and the higher the residual sugar, the more viscous the beer is, so the higher the temperature, the more carbon dioxide is released. However, more foam is not always better, especially when the bottle is opened and poured into the glass, a large number of bubbles appear to \"spray\
? One is that the brewing raw materials may be contaminated by some microorganisms, which destroys the formation of \"foaming proteins\
The third is due to improper storage of beer, too high temperature, or excessive vibration when moving.
Fourth, papaya alcohol was added to avoid beer turbidity during the production process. All of these factors can affect the taste and quality of beer.

1. Check the pressure of the gas gauge, and control the low pressure gauge within 0.2.
2. Check the refrigeration effect of the machine, there should be at least 3-4CM thick ice inside the water-cooled draft beer machine, and the thermostat will control the compressor to stop working at a certain temperature.
3. The speed of the wine should be moderate, and the flow rate of the wine head can be adjusted to control the speed of the wine.
4. The newly changed wine or the barrel is almost empty of wine when it is more foam, because there is air in the wine tube. It is recommended to drain the air from the wine tube before drinking.
5. Because yellow beer is easy to foam, the long wine pipe inside the machine must be connected to yellow beer.
6. Check whether the connected wine pipe or trachea has air leakage or wine leakage, and the place where there is air leakage or wine leakage is also easy to foam.

7. Often use CO2 gas or broom to clean the dust and debris on the condenser suction net to maintain a good heat dissipation effect.
If you use a very good draft beer machine, there are about several reasons for foam, 1. The machine is not plugged in or there is no ice in the water tank, 2. The carbon dioxide pressure reducing valve is too low to adjust, when the general ambient temperature reaches 30 degrees Celsius, the barometer is adjusted to more than 3 kilograms of pressure, and the gas meter pointer is above 0.3Mpa, the premise must be the aerobic meter, and many gas meters are automatically deflated when they are not 0.3Mpa.
3. There is air leakage in the wine selling system, check and deal with it.
4. There is leakage phenomenon in the wine sale system, check and deal with the general foam you said, more is to buy a relatively cheap domestic draft beer machine, due to a variety of reasons such as short wine pipe congenital cause, there is no good solution, if you want to better sell alcohol can choose a more high-end draft beer machine can solve the problem of continuous release of wine without foam. Suzhou and Joe Beer machine can solve all your problems
