Recommended Blending Equipment For Nutraceuticals

Source: Charles Ross and Son Company

Dry blending is an indispensable operation in the manufacture of multivitamins, sports supplements, herbal extracts, meal-replacements, green food powders and other nutraceutical products. Many supplement formulators and contract manufacturers accomplish this process on Ross Ribbon Blenders. Ingredients are loaded into a U-shaped trough and mixed by a horizontal agitator consisting of inner and outer helical ribbons. 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.
