The PEGAS manual bottle fillers are designed for fast (1.5 liter within 15 seconds) and foam - free dispensing of carbonated beverages (e.g. beer) from pressurized vessels (kegs).
The PEGAS operation principle imitates an industrial bottle filling process.
It is characterized by:
• Fast filling of a bottle
• Absence of excessive foam
• Hygienic filling
• Beer saturation with CO2/preservation of beer quality
The technology of manual bottle filling through PEGAS is based on the isobaric dispensing using the backpressure method.
Isobaric dispensing means the creation of overpressure above the beer surface as compared with the carbon dioxide balance pressure in the beer.
Backpressure method consists of filling an empty bottle with gas (CO2 or beer gas) under the pressure equal to the pressure in a keg with beer. It requires CO2 of food grade with purity of 99.98%. One CO2 cylinder (25 kg) is sufficient to dispense the amount of fifty kegs (50 - liter each) or 25 hectoliters.
The dispensing procedure is the following:
1. A bottle neck is tightly fixed into the bottle fixing device
2. CO2 is supplied under pressure into the bottle in order to squeeze the air out of the bottle. As soon as the bottle feels solid by touch, CO2 supply stops.
3. The beer supply starts.
4. The bottle filling and the pressure release is regulated manually by adjusting beer supply rate and controlling the foam formation.
5. By the end of bottle filling the CO2 pressure shall be released so that there formed thick foam in the bottle neck in order to prevent beer from the oxygen penetration.
6. To keep beer quality the filled bottle shall be sealed with a cap as soon as possible after bottle unfixing.
The above described technology results in fast, practically oxygen-free dispensing with the preservation of beer quality and without excessive foaming while dispensing.
