A new sanitary Model RCM-60X20-SS Rotary Continuous Mixer from Munson Machinery (Utica, NY) blends primary bulk ingredients, minor ingredients and/or liquid additions uniformly in one to two minutes residence time (typical), at low cost per volume of material blended.
Unlike mixers that force agitators through stationary material, the Rotary Continuous Mixer design employs a 20 ft (6.1 m) long by 60 in. (152.4 cm) diameter rotating cylinder with internal mixing flights that impart a gentle tumbling action, distributing particles with each degree of drum rotation with no shear or heat generation, eliminating or minimizing degradation.
A 30 HP (22.4 kW) gear-reduced motor rotates the mixing drum at slow speeds on external trunnion rollers, minimizing energy consumption and eliminating the need for shaft seals.
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. Spraying of liquid additives onto a wide expanse of cascading material produced by the internal flights minimizes the time required to achieve uniform distribution.
