Purpose

For blending and homogenizing of any free flowing bulk material, within a hopper or silo.

Method of Operation

With its special geometry in the silo hopper, the ProBlend™ Zone Blender provides ten different flow zones in which the material passes through the silo at different velocities and residence times.  As a result, the discharged material contains a blend of material from throughout the silo or hopper.  The Zone Blender uses a combination of mass flow (first in – first out) with funnel flow (last in – first out) to provide a homogenous blend and eliminate the effects of segregation, even with dissimilar materials.

Applications and Benefits

·         May be used in a once-through or recirculating system design, to provide a homogenous blend of material from throughout the silo.

·         Appropriate for batch or continuous systems.

·         Allows re-use of off-spec or recycled material by blending it into the major component.

·         Suitable for mixtures of many ingredients.

·         For the compounder, the resulting homogeneity provides uniformity of color and uniformity of other desired material properties.

·         When installed above the process or packager, it reduces any chance of segregation at the use point – no more variability in the end product.

·        Continuous concept with no time delay required between material feed and blending.

·         In the Chemical industry, suitable for blending or preventingsegregation of any free flowing materials.

      Examples include meal, coffee, cereals, pet and animal food, spices, fertilizer, etc.
