CP fillers are a series of counter-pressure fillers, suitable for filling of carbonated or still (cold or hot) liquids in to glass bottles. 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 bottles 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 bottle, minimizing the product agitation when being filled. The filling height is set by changing the filling tubes on the valve. The filling tubes are clicked on the position, no unscrewing or tools are needed when filling height needs to be changed. The sealing between filling valve and bottle neck, is with the help of pneumatically controlled bottle lifting cylinder.
The changeover between aluminum cans and glass bottle, require only changing the filling tubes and the centering bells, therefore the changing is fast, and no tools are needed. 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 vacuum circuit, CO2 circuit and the pressure release systems (snift). Despite a higher level of complexity, CP line of counter-pressure fillers are still user friendly.
- Product inlet
- Vacuum
- Injection gas
- Counter pressure gas
Method of operation Bottle filling:
Filling sequences consist of the following steps:
- Bottle double deaeration with vacuum and CO2 gas
- Bottle pressurizing
- Product filling
- Snifting- pressure releasing
- The bottle is transported to the filling position in the fillers turret with the help of a star wheel. The filling position consist of pneumatic bottle-lifting piston and the counter-pressure filling valve, mounted on the pressure tank. The piston lifts the bottle and makes a tight seal with the filling valve by pressing the bottle neck against rubber seat on the valve.
- When bottle is on filling position and sealed with the valve, the vacuum is activated to evacuate the air in the bottle. Vacuuming is activated by the cam mechanically pressing the vacuum button on the filling valve.
- The vacuumed bottles is than injected with CO2 gas. When filling in deaerated bottled, the product is exposed to the CO2 gas only, reducing the oxygen absorption. The vacuuming-CO2 injection of the bottle is repeated 2 times, in order to have complete evacuation of the air, the bottles have been double deaerated.
- After the bottle is pressurized with CO2 gas, the product pouring can start, the butterfly will be lifted and valve opened. Filler is equipped with “no-bottle, no-fill system”, which will not activated filling, if no bottle is detected on the filling position.
- When product pouring is completed, the butterfly is pressed and filling valve is closed.
- Filled bottle is carefully depressurized, via the snift button, preventing product fobbing.
- After the filling process is completed, the piston is lowered and the bottle transported from the turret with the help of a star wheel.
Method of operation cans filling:
Filling sequences consist of the following steps:
- Can double injection with CO2 gas
- Can pressurizing
- Product filling
- Snifting- pressure releasing
- The cans are transported to the filling position in the fillers turret with the help of a star wheel. The filling position consist of pneumatic bottle-lifting piston and the counter-pressure filling valve, mounted on the pressure tank. The piston lifts the can and makes a tight seal with the filling valve by pressing the can lip against rubber seat on the centering bell.
- When can is on filling position and sealed with the valve, the CO2 injection is activated by the cam mechanically pressing the injection button on the filling valve. The CO2 injection of the can is repeated 2 times, and pressure is released between them, to have complete evacuation of the air in the cans. When filling in deaerated cans, the product is exposed to the CO2 gas only, reducing the oxygen absorption.
- 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.
- After the filling process is completed, the piston is lowered and the filled can transported from the turret with the help of a star wheel.
Main features:
- Filler pressure tank with product infeed from the bottom, and with CO2 and vacuum ring chambers, which supplies the gases to the filling valve.
- Counter-pressure filling valve, with bottle centering bell, vacuum, CO2 injection and snift buttons.
- “no-bottle no-fill system”, if no bottle is not detected on the filling position filling will not start.
- Pneumatic bottle-raising pistons, operated with air trust and cam return. Externally mounted for easier cleaning and easy maintenance.
- Electrical height adjustment, without locking mechanism or tools 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.
Cleaning in place:
Filler consists of integrated CIP system, with CIP cups, which allows fast and thorough cleaning or sterilization of all the filler components, which are in contact with the product, as the vacuum circuit, CO2 circuit and the pressure release systems (snift).
