Principle and Operation

The Rospen Flavour Coating System has been designed to continuously weigh the flow of products such as snack foods, extruded products etc to ± 1% and accurately add flavourings, coatings or colourings in exact pre-set ratio.

Consisting of a standard Rospen weigh belt, sized to suit the required product throughput the flavour coating system continuously and accurately measures the product process flow rate and through the Rospen PLC is displayed in kg/hr. The flow signal is then used to modulate the speed and product output rate of a Rospen metering feeder complete with spreader tray, in direct ratio, which then adds flavourings or coatings to the main flow of product by the use of a coating drum, which tumbles the product for a controlled period of time ensuring a perfectly even and effective coating.

Alternatively, the ratioed coating can be applied in liquid form via a metering pump and sprayed directly onto the product within the coating drum.
