Efficient recovery of active pharmaceutical ingredients (APIs), chemical substances or food powders after drying applications such as spray and fluid bed drying is frequently a problem. The same problem occurs in many milling and micronization applications.
The preferred way to recover these sensitive products is with cyclone collectors due to their direct powder capture. Unlike bag filters or wet scrubbers, cyclones minimize filter or product contamination and product cross contamination and can easily handle a wide range of operating temperature, pressure and moisture conditions.
The current problem with cyclones is their low efficiency. And therefore, when necessary, cyclones have to be complemented with expensive specialized bag filters or wet scrubbers to increase yield or to avoid emissions to the atmosphere.
Client's needs include a high efficiency cyclone system that dramatically increases powder yield, is easy to clean and is efficient enough to comply with regulatory PM emission limits, thus avoiding the use of secondary filters.
