COMBER at ACHEMA 2018: Supreme flexibility in use with maximum drying performance
COMBER is presenting select product highlights as well as the sophisticated functionality of its tried and tested Condry vacuum dryer at this year’s ACHEMA. Visitors to stand B8 in Hall 5.0 can experience the full expertise of the specialist for (nutsche) filters, filter-dryers, paddle dryers and pan dryers.
The agitated vacuum dryer of the COMBER Condry TDC series in a vertical arrangement with conical bottom in cGMP compliant design has been developed for the drying of valuable pharmaceutical ingredients (API’s) or intermediates. High drying efficiency, gentle product handling, prevention of product losses, excellent cleanability and inspection as well as outstanding operational reliability and exceptional cost effectiveness are integral characteristics of the Condry dryer.
Sophisticated shaft system
A unique agitator arm profile with teeth avoids excessive pressure onto the product and thus prevents changes or damage to the crystal structure of the product. At the same time, it allows effective and uniform mixing of the
entire product mass at low rotational speeds without forming agglomerates.Thus no choppers are required, whose shear action would cause damage to the product in addition to the excessive dust which would be created in the final drying stages. Large heating surfaces ensure optimal heat transfer for the best possible dryer performance in short cycle times. Narrow tolerances between the agitator and the vessel walls prevent adhering of the product to the walls and good emptying characteristics and permit the use of the dryer with small product volumes.
Elaborated Agitator
The agitator is supported from the top only, with simultaneous rotational and vertical agitator motions. An externally accessible double mechanical seal and a convoluted bellows provide sealing for the agitator motions. Product discharge is through a bottom mounted ball or segmented ball discharge valve. With the base lowered the internals of the machine are fully accessible for cleaning and inspection purposes. In addition, the flexible universal dryer is ATEX certified according to the EU directives 2014/34/EU.
COMBER, founded in 1960, is one of the leading manufacturers of (nutsche) filters, filter-dryers, paddle dryers and pan dryers for the chemical, fine chemical and pharmaceutical industry. They are used for discontinuous solid-liquid separation, efficient cake washing including suspension washing as well as vacuum drying of the product with all processes taking place in a single machine.
