HEMF - Electronic mass meter filling system

HEMF - Electronic mass meter filling system

The filling machines of the renewed HEMF series, manufactured according to the new HYPER CLEAN characteristics, are suitable for the MASS filling of oil in PET bottles.

HEMF fillers are characterized by:

  • high precision mass flow meter (flow meter that uses the Coriolis effect to determine the exact quantity of product at each passage) installed for each filling valve;
  • simplified filling valve, with reduced number of gaskets, capable of managing two filling stages (slow filling and fast filling);
  • special NO DROP filling valve, specifically designed for filling oil in PET bottles, with specific anti-drip function at the end of filling;
  • no contact between filling valve and bottle during the filling;
  • reduction of costs and time dedicated to maintenance of the filling valve.

The machine is complete, in the basic version, also with the following features:

  • 7” HMI (15” HMI available as an optional);
  • Parameters of each format to be directly managed through HMI;
  • Quick changeover of the bottle guide equipment;
  • Product pump to maintain constant pressure during filling;
  • Compact frame for space saving in the filling line and reduced transport costs.

Available in various sizes to cover a wide range of production, the machines of the HEMF series are available in the filler/capper, rinser/filler/capper versions or in the innovative ECOBLOC® version where the ENOBERG filler-capper block is combined with the SMI stretch-blow moulder.

Advantages of filling with mass flow meters compared to filling by weight with load cells:

  • Fast measurement with greater repeatability;
  • No tare needed;
  • No moving parts, in other words, no maintenance costs related to the flow meters;
  • Valve monitoring and automatic compensation possible via PLC;
  • No volume limit (the size of the bottle is not limited by the type of load cells);
  • Greater stability and less calibration required on the flow meter lifecycle;
  • Less impact of environmental conditions on the functioning of the flow meter (mechanical vibrations, agitation, splashes, etc).

PET bottles are transported inside the machine through an air conveyor. The bottle flow is regulated using a pneumatically operated gate which, depending on the condition of plant production, enables or blocks the bottles transfer to the first star wheel.

Bottles coming from the air conveyor are transported towards the rinser. This transfer is performed through a rotating star wheel which receives the bottles from the air conveyor, handling them by the neck, and transports them towards the rinsing carousel.

The bottle coming from the star wheel reaches the rinsing turret where a rubber gripper grabs the bottle neck, and by using a mechanical cam system inverts the bottle (180 degrees) in order to have the bottle lip aligned with its rinsing nozzle. The nozzle is activated, dispensing water or air depending on the filling product and on the customers preference. At the end of the rinsing phase, the bottle is inverted again, coming back to the initial position. The bottle is ready to be moved to the rinsing carousel. Each rinsing turret is equipped with a “no bottle-no spray" system: a sensor placed close to the rinser inlet detects the presence of the bottle. In the event that no bottle is detected, the correspondent turret will not perform any rinsing operation.

Bottles coming from the rinser are moved towards the filler. This transfer is performed through a rotating star wheel which collects the bottles from the rinsing turret, handling them by the neck, and transports them towards the filling carousel.

The bottle coming from the star wheel reaches the filling turret where a gripper grabs the bottle neck keeping it lined up under the filling valve. This filling technology does not involve the contact between valve and bottle. The filling product is contained in an external tank from which, through a pump, it is conveyed to the filling valves. The filling system is electronic volumetric with magnetic flow-meters (EVF models for conductive products) or electronic by mass with flow-meters based on the Coriolis principle (EMF models for non-conductive products). A gauge is connected to each filling valve. Once the movement has started, the gauge measures the quantity of product going through the valve. The counting method is pulse-based: when the set value is reached, a closure sign is sent to the filling valve. The filled bottle is ready to be moved to the capping turret. Each filling turret is equipped with "no bottle-no fill" system: in the event that no bottle is detected in the filling turret, the filling operation will not start.

Bottles coming from the filler are moved towards the capper. This transfer is performed through a rotating star wheel which collects the bottles form the filling turret, handling them by the neck, and transports them towards the capping turret.

The bottle coming from the star wheel reaches the capping turret where a star shaped mould allows the bottle centering under the corresponding capping turret. The cap coming from caps feeding system is picked up by means of a star wheel called "pick and place". The capping head collects the cap from the star wheel and it applies the cap to the bottle. Depending on the cap to be applied (plastic screw cap or plastic pressure cap), the capping system may be rotating or by-pressure. The rinsed, filled and capped bottle is ready to be moved to the outlet conveyor. Each capping turret is equipped with "no bottle-no cap" system: in the event that no bottle is detected under the capping turret, the cap will not be applied.

The rinsed, filled and capped bottles are transported out of the machine through an air conveyor. This conveyor is equipped with automatic height adjustment which allows the bottle point of support to be tailored to the bottle height.



  • Modular structure which can be customized;
  • Compact filling module which minimizes the number of stars for bottle handling, while ensuring an easy access for maintenance and cleaning;
  • Modular framework which allows optimization of the shipping dimensions, cutting the transport costs and making the machine suitable for standard road transport;
  • Low operating and maintenance costs;
  • Low risk of contamination, high level of hygiene;
  • Excellent price performance ratio.
