Crisps / Snack Flavouring
Rospen Metering Screw and Vibratory tray feeders are the NUMBER 1 CHOICE for the application of Salt and Flavouring powders for Snack products and are installed worldwide, by leading Snack Food manufacturers, the line builders and equipment suppliers to the snack food industries. In these applications, Rospen feeders have demonstrated the precision and long term reliability demanded by modern manufacturing processes, and the ability to accurately dispense the full spectrum of these often difficult to feed powders. With the extent of Rospen Industries involvement worldwide, in fact on all the 5 continents, it is more of a question as to where Rospen have not supplied Flavour Powder Feeders. So, wherever you are in the world and you require further information or wish to discuss your plant requirements, please follow the link to our contact form and we will respond accordingly.
