Efficient recovery of Active Pharmaceutical Ingredients (APIs), chemical substances and 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. For the recovery of these sensible products, cyclone collectors are frequently irreplaceable equipments for being able to capture the powder directly, avoiding filter holdup. Cyclones also avoid contamination of filter bags, product cross contamination and product degradation with temperature. (see Figs. 1 & 2 below)
However, product losses due to cyclones’ low efficiency represents a high cost as a consequence of the value of APIs. Where applicable, cyclones have to be complemented with bag filter in order to avoid emissions to the atmosphere.
Hurricane Cyclones A completely new set of cyclone geometries
Numerically optimized Hurricane cyclones demonstrate impressive efficiencies in capturing inhalable powders with a Median Volume Diameter (MVD) of less than 3-5 m. (see Fig. 3).
Hurricane geometries maximize powder collection for each different application, while minimizing re-entrainment and keeping pressure drop at reasonable levels. A single Hurricane is more efficient than any other known cyclone available in the marketplace for the same pressure drop. Hurricanes have demonstrated efficacy in replacing cyclone and filter arrangement and complying with regulatory emission limits in chemical and food powder coating applications (< 30 mg/Nm3).
ReCyclone® Systems Introducing Mechanical and Electrostatic Recirculation
A ReCyclone is composed by a Hurricane and by a particle separator (mechanical or electrostatic recirculator), placed downstream of the cyclone.
The main purpose of the recirculation is to reintroduce the fine non-captured particles into the cyclone after those have been driven to the outer walls of the re-circulator by centrifugal or electrical forces. While this tangential gas stream is enriched in particles, the axial gas stream exhaust to the stack is practically invisible, comparable to bag filters. (see Fig. 4).
Efficiency increases due to recirculation and agglomeration of very small particles with larger ones coming directly from the process, reaching 99 % for many fine powders and assuring emission limits compliance.
