New Food Pharma Systems Spiral Jet Mill.
Combining Air Jets with Mechanical Classification.
Spiral jet mills offer a variety of advantages compared to other mixed air jet-mechanical technologies combining air jets with mechanical classification:
- Absence of moving parts, hence avoiding heat generation, friction, lubrication
- Clean micronisation effect generated by laminar air jet stream (no turbulences)
- Light-weighted equipment
- Easy-to-assemble-disassemble without special tools
- Easy-to-clean
- Short turn-around times
- High productivity
- Limited contact surfaces
- Very narrow particle size distribution
- 99.5% production yields
- Single collecting point (dimensional homogeneity)
- Low process gas and electrical consumptions
- Low capital investment
- Practically no maintenance required

For best results the basic and typical components of a spiral jet mill systems are indicated in the drawing you find hereafter, i.e.:
- feeding unit
- spiral jet mill
- cyclone separator with internal filtering system
- air control manifold and control panel
The system works with pressured gas (normally air or nitrogen) from 3barg (or less) up to 12barg. Pipings can be flexible food grade plastic or in stainless steel, valves can be of several types from manual ball valves to fully automated membrane valves, or other types. The micronisation system can be fully closed and EEx (10 bar resistant).
The system itself can be totally contained in isolators (glove-boxes), alternatively in Down-Flow or Down-Cross Booths, or simply in Clean-Rooms as you can see in the Containment section of this website. CIP, SIP, ATEX and many other executions and options are also available. Full automation via PLC, gravimetric feeding unit, inline analyser also possible.
