Beer Dispenser - Backpacks

A Beer dispenser system consists of one or more taps (usually a compensator tap) and fittings for connecting the storage containers, usually barrels, plus a pump or a pressurized gas container, also called a carbon dioxide or nitrogen bomb, with a pressure reducer suitable for this purpose.

  • For heating or cooling the beverages, the beer dispenser can be equipped with appropriate equipment. 
  • As a rule, continuous flow coolers are used here, which cool the beverage while it is being poured.

A distinction is made between wet and dry coolers, with the somewhat outdated wet coolers using a cold water basin, whereas the dry cooler uses a cold aluminum block through which cooling coils with the beverage run. 

  • Beer dispenser tap systems are typically used in the beer service industry or where beverages are dispensed in large quantities. 
  • The quantity to be filled can be dosed manually or automatically.
  • In the meantime, there are also beer dispensing systems where ready-to-drink beers are filled from canisters into drinking vessels at the push of a button.
  • Smaller home beer dispenser systems for small beer kegs and private use are also on the market.
  • A component of dispensing systems for beers, especially for draft beer, is usually a collecting device for the over foamed or skimmed beer foam.
  • It consists of a tub under the tap, usually covered with a perforated, grid or slotted plate, in which the liquid is caught and collected.
  • In the past, so-called leak beer was often served at a lower price to financially less fortunate customers.

Beer Dispenser equipment

  • Through technical dispensing controls associated with the system, the correct dispenser technique and the correct pressure on the pressurized gas line, the so-called dispensing loss can be minimized.
  • The CO2 content of the beer:
  • the more carbonating CO2 present in the beverage itself, the higher the corresponding back pressure must be to prevent the carbon dioxide from dissolving.

Tap pressure of the beer dispenser?

  1. A pressurized gas such as CO2 is used to move the beer from the storage container to the tap.
  2. This gas flows into the container and ensures the buoyancy of the beer via a riser tube and the maintenance of the carbon dioxide content of the beere in question.
  3.  A pressure reducer is connected to the pressurized gas container, as the pressure directly at the valve would be too high. 
  4. Setting the correct tapping pressure on this is essential for tapping.
  5. This should depend on the following factors:
  • The temperature of the beer: 
  • The higher the temperature of the beer in the container, the more easily the carbon dioxide dissolves and the higher the counterpressure must therefore be.
  • The difference in height from the container to the tap: the higher the beer has to be transported in the fittings, the higher the driving pressure must be.
  • The other portion is exclusively responsible for transport to the beertap.
  •  At the tap, the pressure is then reduced again to prevent carbon dioxide loss and to produce a moderate flow of the beverage. 
  • This is usually referred to as an adjustable " compensator tap" 

Cold Beer Dispenser

  •  In case of deviations from normal beer quality!
  • If a beer smells or tastes untypical, in the worst case a filtered beer comes out of the tap cloudy or flakes float in it, then the dispensing equipment most probably has a strong microbiological infection.
  • Also in this a basic cleaning is absolutely necessary, because the infection cannot be removed from the infection cannot be removed from the system with the normal weekly cleaning.
  •  In case of apparent abnormalities
  • A beer dispenser system should be visually inspected by the operator or a specialist at regular intervals.
  •  If during the inspection it is noticed that coatings have formed in the hoses, or that slime or mold stains appear in various places, or that sour smells are detected at the tap or dispensing head, or dull smells are detected at the tap or dispensing head, it is also urgently time to have a time to carry out a basic cleaning.
  • Beer Dispenser

  • With most models, precise pressure adjustment is not possible here, as the air flows directly from the beerpump.
  • As an alternative to pressurized gas, there are also beer dispenser systems with diaphragm pumps, which use a moving diaphragm to create a negative pressure that transports the beer into the line and to the tap instead of, for example, CO2.
  • Carrying out cleaning and disinfection?

  • The length of the line and its diameter: the longer the line and the smaller its cross-section, the higher the friction with the beer and therefore the driving pressure.
  • The portion of the pressure that is dependent on temperature and CO2 content is called the saturation pressure of the beer.
