Many food manufacturers, flavor houses and toll blending companies rely on Ross Ribbon Blenders for their seasonings, spices and herb mixes. Dry ingredients are loaded into a U-shaped trough and mixed by a horizontal agitator consisting of inner and outer helical ribbons. Liquid additions are made by pouring or spraying into the batch as the agitator is running. The position and precise pitch of each ribbon produce a well-balanced axial and radial flow pattern, promoting fast and thorough mixing.
Maximum tip speeds are approximately 300 ft/min but with variable speed control, the blending action can be fine-tuned and optimized according to the characteristics of a particular recipe. Ground spices like cinnamon, cloves and ginger benefit from high rpm, short duration blending cycles. More fragile blends containing whole spices and leaves may require gentler mixing. In addition to speed control, a Ross Ribbon Blender can be equipped with an interchangeable paddle agitator to maximize the range of shear input.
In many plants, the multi-purpose Ross Ribbon Blender is not only used for seasonings and spices but also other blends like powdered beverages, sweeteners, baking pre-mixes, flavors, coffee, food additives and trail mixes. Even “wet” products like soups, cake batter and sandwich salads are also prepared in Ross Ribbon Blenders. This machine is easy to clean and wash down so product changeovers are quick and operator-friendly.
