CAN FILLING
VOLUMETRIC FILLER
The volumetric filling turret with electro-pneumatic spout consists of the following main elements:
1. Electric turret height adjustment
2. Motion transmission
3. Pneumatic can lifting pedestal with cam return and automatic lubrication
4. Dummy centralized can
5. Electro-pneumatic filling valve
6. Flow meter
7. Pressure annular tank (maximum pressure 4 bar)
8. Electro-pneumatic filling valve control
9. Gas and compressed air distribution
10. Electrical supply The volumetric filling valve avoids any return of the product into the tank, excluding any possible contamination and oxidation of the product inside the vessel. The filling volume is adjustable from the control panel without manual intervention, depending on the capacity of the container. Each valve is equipped with a dummy can for cleaning and sanitizing the machine. The dummy cans are mounted on the filler, with manual positioning and centralized unloading. All the circuits are canalized and the filler is prepared for a sanitizing CIP circuit. The valve can operate with a pressure up to 4 bar. The filler has an analogical level sensor suitable to administrate the feeder pump inverter. The gas pressure in all circuits is automatically handled by PLC. The filler is equipped with external washing of the filling valves.
VOLUMETRIC FILLING VALVE
STRENGTHS This filling valve with electro-pneumatic operation has important features and is integrated with the turret in order to optimize the washing cycle with the application of dummy cans. The main features, which determine the strengths of the entire construction, are the following:
1. FLEXIBLE FILLING All the working parameters, such as pre-flow and can flushing, working pressure (from 0.5 to 4 bar), volumetric filling and degassing cycle, are set on the control panel and can be modified without any manual intervention by the operator .
2. FLOW METER ADJUSTMENT The flow meter adjustment determines the amount of beer fed into the can. If the capacity of the can varies, simply set the new value on the touch-screen.
3. CENTRALIZED DUMMY CAN Manual and simultaneous positioning of all the dummy cans, always present on the machine.
4. SAFETY OF THE SANITIZATION CYCLE The electro-pneumatic actuated valves, together with the presence of dummy cans with discharge circuit, allow to create well defined sterilizing cycles for each filler circuit.
5. REPEATABILITY OF OPERATION The filling cycle, managed with timing phases, ensures the maximum working cycle repetition, leaving it unaffected to speed variations on the production line.
6. PRESSURE TRANSDUCER The pressure transducer, on the edge of every filling valve, allows checking in every moment the can pressure so to control that the filling cycle is carried out correctly and to find possible anomalies or malfunctions. These controls carried out allow for example to detect: damage to the shutter and cone centering gaskets, effectiveness of the pre-flow and fluxing, defective can, etc. Moreover, it is possible to check the efficiency of every single filling valve.
7. CONSTRUCTION WITH 4 ELECTROPNEUMATIC VALVES
Use of 4 electro-pneumatic valves to control separately the circuits of:
• GAS PREFLUXING AND RETURN FILLING
• FLUSHING
• GAS FLUX RETURN
• DEGASSING
8. STORAGE OF THE RECIPE
The filling cycle is set through the control panel and it does not require any manual intervention on the filler. Saving cycles and recalling them simplifies and speeds up the changing format operation, thus enabling a more uniform production.
