A draught beer machine is a device that delivers beer to a glass using the principle of pressure. Its operating principle is mainly divided into the following steps:
The beer keg is installed inside the draught beer machine, connected to the beer outlet via pipes. The draught beer machine is equipped with a compressed gas cylinder, typically a carbon dioxide cylinder, which can adjust the pressure of the compressed gas through a pressure regulating valve.
When a customer orders a drink, the draft beer machine activates, releasing the gas from the carbon dioxide cylinder into the beer keg, increasing the pressure inside. As the pressure builds, the beer is pushed to the tap.
Next, the operator opens the spout, and the pressure from the compressed gas pushes the beer out of the cask, through the pipes to the glass. During the pouring process, the draft beer machine typically regulates the speed and amount of beer dispensed to ensure the consistency of the beer's quality.
Once the beer is poured into the customer's glass, the operator closes the dispensing spout and simultaneously stops the supply of compressed gas. The beer dispensing process is then complete.
Through the series of operations of the draught beer machine, customers can conveniently and quickly enjoy fresh beer in bars or restaurants. This automated process not only enhances the efficiency of beer dispensing but also ensures the stability of beer quality and hygiene safety.
