What does a ROSS Ribbon Blender do? The batch-style ROSS Ribbon Blender is a proven workhorse in bulk solids processing. From seasonings and beverage mixes to pharmaceutical, chemical, plastic, and agricultural powders or granules, the wide range of applications that are efficiently and economically processed in a ROSS Ribbon Blender makes it a popular and versatile choice in various industries. This blender can heat, cool, or dry materials under vacuum. It can also coat solid particles with small amounts of liquid. In addition, it can mix wet applications such as soups, batters, slurries and certain pastes. How does a ROSS Ribbon Blender work? Ribbon Blenders consist of a U-shaped horizontal trough and a solid agitator shaft mounted with spokes that support outer and inner helical blades called ribbons. Powered by a gearmotor drive, the agitator rotates and produces a peripheral speed of up to approximately 300 fpm. The ribbons move material radially -- the outer ribbons move the ingredients in toward the blender’s center, and the inner ribbons move ingredients out toward the blender wall. The difference in the outer and inner ribbons’ speeds moves material laterally or axially (along the blender’s horizontal axis), in opposite directions. The radial and two-way axial mixing actions promote small-scale random motion (diffusion), large-scale random motion (convection), and shear resulting from particle-to-agitator, particle-to-wall, and particle-to-particle collisions. Design – ROSS Ribbon Blenders are fabricated from thick, high quality stainless steel wetted parts, in sizes ranging from ½ to 1000 cubic feet working capacity.
