Project Description
Increasingly, leading pharmaceutical manufacturers worldwide are developing continuous processes using hot melt extrusion (HME), considering this an attractive alternative to traditional batch production. BBA INNOVA, a Swiss company specialising in cooling/solidification/flaking and optional milling of the melt, has developed pharmaceutical «drum cooler» units, with FDA-approved materials and GMP design, providing full access to and inspectability of the parts in the process area and clear separation of this area from the «service» area. The molten product («hot melt»), discharged for example from an extruder, is conveyed between the two refrigerated cooling rollers and the belt presses the product against the main roller to optimise heat transfer; subsequently, the solidified product is reduced to flakes by the flaking unit (patented design).
