CP fillers are a series of counter-pressure fillers, suitable for filling of carbonated or still (cold or hot) liquids in to aluminum or PET cans. The fillers are mechanical type, where the individual filling steps are mechanical operated with cams. Filler consist of a rotary carousel, a pressure bowl, with set of filling valves, allowing filling of multiple cans at the same time in continues motion, without stopping. Product is feed to the pressure bowl from the bottom, minimizing product agitation, and allows better emptying of it. Product level in the filler bowl is controlled with capacitive sensor. The operator can precisely choose the starting and stopping point of the product inflow, as the minimum product level, which alarms the operator, or stops the filling sequence. All the settings are done on the touch screen control panel. Filler height adjustment is powered by electric motor, for simple and fast height adjustment, even in operation, no locking mechanism or tools are needed.
The pressure in the tank is computer controlled via a digital pressure sensor, the pressure is precisely maintained inside the tolerance of ±0,05 bar of set pressure, eliminating pressure spikes or drops when product is filled or infeed in the filler. Filling valves are built from machined stainless-steel parts, with no welds or threads in contact with the product. Thanks to our special design of the filling valve, liquid is gently poured on the side of the can, minimizing the product agitation when being filled, and same product level is obtained on all the cans. The sealing between filling valve and can lip, is with the help of pneumatically controlled centering bell. With low sealing pressures, and carefully designed contact seal, the can lip cannot be damaged, which could result in lid seaming problems.
Filling sequence consist of the following steps:
- Can flushing with CO2 gas
- Can pressurizing
- Product filling
- Snifting- pressure releasing
Filler consists of integrated CIP system, with CIP cups, which allows fast and thorough cleaning of all the filler components, which are in contact with the product, as the CO2 circuit and the pressure release systems (snift). Despite a higher level of complexity, CP line of counter-pressure fillers are still user friendly,
Method of operation:
- The aluminum can is transported to the filling position in the fillers turret with the help of a star wheel. The filling position consist of the counter-pressure filling valve, mounted on the pressure tank.
- When can is on filling position the CO2 injection will be activated, and can is flushed, to replace the air in the empty can with CO2 gas. When filling in inerted cans, the product is exposed to the CO2 gas only, reducing the oxygen absorption. At the same time of injection, the valve centering bell is lowered and tight fit is made between the can and filling valve.
- After the can is pressurized with CO2 gas, the product pouring can start, the butterfly will be lifted and valve opened. Filler is equipped with “no-can, no-fill system”, which will not activated filling, if no can is detected on the filling position.
- When product pouring is completed, the butterfly is pressed and filling valve is closed.
- Filled can is carefully depressurized, via the snift button, preventing product fobbing.
- The centering bell of the valve is being lifted with the help of a mechanical cam, and filled cans are transported off the turret, with the help of a star wheel.
Main features:
- Filler pressure tank with product infeed from the bottom, and with CO2 and pressurized air ring chambers, which supplies the gases to the filling valve.
- Counter-pressure filling valve with pneumatically controlled centering bell, CO2 injection and snift buttons.
- “no-can no-fill system”, if no bottle is not detected on the filling position filling will not start.
- Electrical height adjustment, without locking mechanism or tools are needed.
- Pressure sensors in the filler bowl for precise automatic pressure regulation.
- Analog pressure gauge on the filler bowl.
- Temperature sensor in the filler tank.
- Liquid level sensor in the filler tank for product infeed control.
- CIP cups for close system cleaning.
