The Ross Model 42N-36S Sanitary Ribbon Blender (pictured) has a 36-cu.-ft. maximum working capacity. Driven by a 25 HP inverter-duty gearmotor, the fabricated double ribbon agitator turns to up to 40 rpm within the U-shaped trough, producing a balanced lateral and radial movement of batch materials. Wetted parts are stainless steel 316 polished to 150-grit for ease of cleaning. The blender cover includes safety grating and a custom bag dump station. A 150-psig ASME code stamped dimpled stainless steel jacket is supplied around the trough for heating/cooling.
