Operating characteristics: Low product shear, low product energy absorption, low thermal stress, high mixing accuracy, high turn-down, self emptying.

Bolz-Summix cone screw powder dryers are used for drying solvent or water wet powders.
The wet powder is charged in to the top of the dryer. The product is agitated and indirectly heated via the dryer jackets. Vacuum is pulled on the dryer vessel reducing the boiling point of the solvent, increasing the possible ΔT and allowing thermally sensitive product to be safely dried. The dryer’s agitation system produces a 3-dimensional mixing action, the mixing screw conveying the powder from the bottom to the top of the dryer while the orbit arm moves the mixing screw through the powder around the dryer periphery. The dryer’s mixing screw can be heated to reduce drying time and minimize product sticking to the flights.

Bolz-Summix cone screw blenders are used for batch mixing of powders or as a live hoper feeding downstream equipment such as dryers, mills etc. The mixing system allows gentle but complete blending of powders with similar or widely differing bulk densities, even powders with a tendency to segregate. The action of the mixing screw and orbit arm quickly homogenize the entire batch while minimizing particle attrition.
Powders are charged in to the top of the blender. The agitation system produces a 3-dimensional mixing action with the mixing screw conveying the powder from the bottom to the top of the vessel while the orbit arm moves the mixing screw through the powder around the blender's periphery.

Bolz-Summix pilot cone screw powder dryers are used for drying solvent or water wet powders.
The wet powder is charged in to the top of the dryer. The product is agitated and indirectly heated via the dryer jackets. Vacuum is pulled on the dryer vessel reducing the boiling point of the solvent, increasing the possible ΔT and allowing thermally sensitive product to be safely dried. The dryer's agitation system produces a 3-dimensional mixing action, the mixing screw conveying the powder from the bottom to the top of the dryer while the orbit arm moves the mixing screw through the powder around the dryer periphery. The dryer's mixing screw can be heated to reduce drying time and minimize product sticking to the flights. Results from pilot scale dryers can be scaled to provide data for production scale units.

To serve the specific requirements of the R&D market Bolz-Summix has developed the miniDRY® laboratory cone screw dryer blender: working volume of 150 ml to 1.5 litres.
At R&D stages, with only small product quantities available, the miniDRY® fills a growing market niche.
Developing the miniDRY® in collaboration with a premiere Swiss pharmaceutical manufacturer's R&D department, Bolz-Summix has brought together the best in equipment manufacturing with the most demanding of R&D companies. The result is a sophisticated, flexible lab dryer with interchangeable agitator options, range of ancillaries and full control, instrumentation and data logging. The unit is mounted in a mobile structure and can be installed in a laboratory walk-in fume cupboard.

Bolz-Summix and Heinkel ball segment valves are powder valves suitable for applications requiring powder or pressure/vacuum tight sealing. Typical applications are as feed and discharge valves for powder dryers and also reactor charge valves. A 90° rotation moves the ball segment from the fully closed to the fully open position. It allows obstruction free powder handling and guarantees re-sealing on closure when used with the unique Bolz-Summix inflatable seal.

Options: CIP connections, inspection ports,
