Continuous gravimetric multi-ingredient feeder, designed to blend pellets in extrusion processes which require precise and consistent blending. Unaffected by vibrations, COMPO has been designed to be easily mounted directly onto the extruder throat to replace the conventional feed hopper.
Compo – Continuous gravimetric feeder and extrusion control
- COMPO is available in 12 models: 2, 3, 4, 5 or 6 ingredients, with throughputs of 150, 300, 600, 1000 up to 2000 kg/h.
- Inclined screw feeders to improve metering accuracy and to prevent undesired dribble. They are driven, with a wide range of speeds, by DC motors with long-life brushes and closed-loop speed regulation.
- Auger screws suitable for granules or free-flowing powders.
- All parts that come into contact with the ingredients are made of satin stainless steel, or of food-grade materials or finishes.
- The on-board control box does not require any floor space.
- Standard supplied integrated refill valve, slide gate type.
- Easily accessible auger screws for quick and thorough cleaning, no tools required.
- Reduced installation costs. Complete wiring of the dosing unit is carried out by the manufacturer.
- Drain spout for easy and quick hopper emptying.
- Manual slide gate for auger screw inspection without hopper emptying.
- Practical and easy access to all components.
- Feed hoppers with sight glass for visual level control and quick-release ring clamp for easycover removal.
- Self-supporting structure suitable for pre-storage hopper and/or vacuum loader installation without additional supports.
- Dedicated standard weights kit for load cells calibration.
CONTINUOUS GRAVIMETRIC FEEDER OPERATION
- Continuous loss in weight control:
- Weight loss of main ingredient is sensed.
- Weight loss of side ingredients is sensed.
- The side ingredients are simultaneously metered in the static mixer where they are mixed with the main ingredient flowing down, by gravity, from its feed hopper.
- The feeders of the side ingredients are individually controlled to achieve and maintain the preset blend ratios with the main ingredient. This means that the blending throughput is always aligned with that of the processing machine.
Integrated loading system control (SmartConvey)
Fully automated loading system control, easy operated by the same interface used for gravimetric blenders. One or more vacuum pumps to serve more than one receivers whose association can be set through configuration. All receivers linked to the same pump are served in turn, according to a priority sequence automatically assigned. Loading active control to reduce ingredient at minimum on changeover
Extruder throat adapter
- Extractable grate magnets on request
Extruder throat adapter
- Custom made with drain spout and manual slide gate as standard.
Low-level sensors
- Capacitive low level sensor
- Paddle low level sensor in case of regrind or flakes
Encoder kit
- Required when yield control is supplied, for line speed measurement
Pre-storage hoppers
- Also available for mezzanine mounting.
Side component dosing
- Volumetric feeder for additives designed to be mounted on a neck riser, between the processing machine feed hopper and the extruder throat.
Materials suction lances
- Different designs to ensure optimal suctioning regardless of the material bulk density.
