Case Study: The Prevention Of Segregation Caused By Uncontrolled Agglomeration During The Drying Of A Pharmaceutical Powder In A Bolz-Summix® Conical Screw Dryer

During start-up of a new Bolz-Summix® conical screw dryer, the bulk product agglomerated due to its sticky nature during a critical phase of the drying cycle. Down stream from the dryer, in the feed chute to the tabletting machine, segregation of the coarse product from the fine gave validation problems. This case study shows, that by slightly differing the process conditions during the drying stages, granulating could be eliminated, minimizing segregation.
