HG-PGZ-8/8/3 type beer bottle rinser-filler-capper 3-1 unit machine is designed combined with the actual situation in our country after the introduction and absorption. It adopts the bottle filling and capping technique of Germany technology. It has been specially used to microbrewery. It adopts isobaric filling principle and filling valve adopts high precision mechanical valve. It has advantages of fast filling speed, high precision in liquid level. 
Adopt Siemens automatic controlling system, realizing trinity of the machines, and control the washing, filling and capping process and realize that it only starts to filling when there is a bottle, otherwise it will stop filling and no broken bottles. The filling process is cleaner and pure due to it’s twice vacuum of bottles, and more stable because of isobaric filling operation.
Using vacuum pump and CO2 preparing pressure to realize a second vacuum ensure no air and bacteria in the bottle, guarantee the filling quality and warranty quality time. Filling cylinder braces use worm-gear box going up and down to satisfy bottles of different height. Float switches in the filling cylinder ensure a smooth liquid inlet. Therefore, this machine is the best ideal choice for beer or beverage factories.
When the filling parts locates between bottle-out and bottle-in star wheel, open the CO2 filling valves and close it after reach the fixed time. So that the CO2 in bottle will blow the remaining liquid.
Capping aprt
Characteristic:
a. The first Vacuumize
Open the Vacuum valve stem, in the bottle and vacuum channels forming a road. The air in the bottle will be discharged from bottle through this channel; in the bottle a vacuum will be formed. After reach the fixed time, Vacuum valve closed, then it will be finished.
b. CO2 injection
Open the filling valve, a pathway is formed between the bottle and the gas channel. The CO2 filling into the bottle through this channel till CO2 pressure in wine tank equals to the beer tank pressure.
c. The second vacuumizing
After CO2 injection into the bottles, little air will be concentrated on the top of the bottle neck. By the second vacuumizing, this part of resting air will be removed and generate a slight-vacuum state, which is better for the filling work.
d. Beer filling
Open liquid valve and form pathway between the bottle and the beer tank, the material will feed into the bottle from this channel, at the same time, the CO2 in bottle return back to the beer tank at the same speed through air-back pipe. Compressed CO2 in the bottle seal material to continue to run till the material in bottle rising over air-back pipe and form pressure balance
e. Close valve
After the bottle finish filling stand for long time, close the liquor valves and air filling valves, cut off the channel between wine tank and bottle.
f. Air discharge
Open the discharge valves and form a pathway between bottle and air. The pressure in bottle will release through this channel and don’t finish release until bottle separate from filling parts.
g. Blow remaining liquid
When the filling parts locates between bottle-out and bottle-in star wheel, open the CO2 filling valves and close it after reach the fixed time. So that the CO2 in bottle will blow the remaining liquid.
