The Ribbon Blender is well-proven technology for cost-effective and accurate mixing of baking mixes. Dry ingredients are loaded into the U-shaped trough and mixed by a horizontal solid-shaft 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 even of very minor ingredients. If present, liquid components are sprayed into the powders at a controlled rate to evenly coat the solid particles as they are being mixed vigorously.
Maximum tip speed of the ribbon agitator is around 300 ft/min. Utilizing a Variable Frequency Drive (VFD), the blending action can be fine-tuned according to the characteristics of a particular recipe, i.e. its density, flowability, tendency to dust, presence of large or fragile particles, etc. The advantage of electronic speed control is significant especially for plants that batch multiple products in one blender. Designed to handle fast-paced and frequent changeovers, Ross Ribbon Blenders are also extensively used for mixing flour blends, spices, sweeteners, bread improvers and other baking ingredients.
As the world’s largest manufacturer of Ribbon Blenders, Ross supplies to hundreds of food companies, flavor houses, toll manufacturers, commercial bakeries, gourmet food stores, food laboratories and raw material suppliers.
