Spectrum Colour Change System

The Spectrum system extends extruder capability by enabling rapid colour changes to be made ‘on the run’ with minimal waste.

High productivity

The skid-based Spectrum system ends the inconvenience and cost of separate runs for each different coloured product, plus the waste, hygiene and shelf-life issues of cumbersome storage and mixing. A typical application continuously runs mixed fruit colours for a single pack; up to five variants are possible – one natural plus four colours.

Easy to use

A liquid feed system to pump water, oil and process colours from holding tanks is controlled from the extruder HMI. Simple, intuitive controls with touch screen interface help operators optimize efficiency.

Easy to clean and maintain

The one-piece stainless steel frame ensures excellent access, with hygienic components and materials used throughout.
