The Munson Machinery rotary continuous mixer blends high volumes of primary bulk ingredients, minor ingredients, and/or liquid additions in 1 to 2 min of residence time. The sanitary Model RCM-60X20-SS mixer employs a 20-ft long by 60-in. diameter rotating cylinder with internal mixing flights that distribute particles with each degree of drum rotation. The mixer’s stationary inlet and outlet allow hard connections to upstream and downstream process equipment, while an internal stainless-steel spray line plumbed through the stationary discharge end permits liquid coating, de-dusting or perfuming of dry ingredients. A weir (dam) at the discharge end of the drum creates a residence bed of material that mixes as it travels through the unit, ultimately overflowing the weir and discharging at rates determined by the residence volume of the rotating cylinder and the rate of material inflow.
