For each batch, an operator uses a drum lift to transfer ingredients from fiber drums into the mixer’s stationary inlet. As the vessel rotates, internal mixing flights tumble, cut, turn and fold the ingredients, achieving batch uniformity in four minutes––11 to 15 times faster than the company’s Vee-cone blenders.
The company also gained production flexibility, as the mixer is equally efficient from 100% down to 15% of rated capacity.
The blended batch is unloaded into GMP-compliant lined fiber drums while the vessel continues to rotate, ensuring a uniform product without segregation. Between batches, the large doors of the vessel allow unobstructed access for cleaning and visual inspection of all product contact surfaces.
According to the company, the Munson Rotary Batch Mixer delivered excellent results in product uniformity in only 4 minutes, compared to 50-to-60 minutes using a Vee Cone blender.
