Munson Machinery’s new sanitary, high-intensity continuous blender, Model HIM-124-S316, provides low to high shear as required for high speed blending and/or homogenizing of dry solids, agglomerates, slurries or pastes when processing food, chemicals, pharmaceuticals or other contamination-sensitive materials. Homogeneous blends can be achieved in as little as 20 seconds residence time depending on material characteristics, at throughput rates to 200 cu ft/h (5.7 m3/h), according to the company. Liquids can also be added in small to large amounts through optional injection ports for de-dusting and agglomerating of dry materials, as well as for producing pastes, emulsions and slurries.
The unit’s horizontal, cylindrical vessel with a single high-speed rotating agitator is supported by externally-mounted bearings with sanitary type seals. Large radius welds joining the large-diameter, solid shaft to blending paddle stand-offs allow rapid cleaning and sanitizing. For wash down, water or cleaning solution can be introduced through the injection ports and retained by an optional gate at the outlet of the discharge chute before running the machine to dislodge any solids adhering to interior surfaces. A flanged outlet on the side of discharge chute allows draining of the liquid.
Constructed of #316 stainless steel and finished to USDA, FDA or pharmaceutical requirements, the blender is available with an insulated low-pressure jacket or high-pressure jacket constructed to ASME code that can be heated or cooled, as processes dictate. The blender and motor are mounted on a common support base. The standard blender drive is a multiple “V” belt and sheave arrangement. Agitator speeds range from 100 to 2500 RPM depending on the application, according to Munson. Optional gear drives are available for reduced speed, high-torque requirements. All drives are furnished with totally enclosed guards. For non-sanitary applications, threaded 180° adjustable paddles for varying degrees of blending intensity are offered as standard.
