The J-40 fluid jet micronizer has been designed on the basis of cGMP principles to mainly work with several types of pharmaceutical and food products. The plant is not foreseen to work with flammable products or products that can generate explosive atmospheres.

The J-40 works at a constant temperature (endothermic) and independently with just a nitrogen bottle. It can be installed in ambient conditions without explosion risks (non classified zones).  The unit is also built to be readily assembled/disassembled and easily cleaned with most common detergents and alcohols.  Furthermore, it offers a very high degree of resistance to powder penetration.

Thanks to its modular design concept, the standard J-40 can be upgraded, on request, to the J-50 or J-70 micronizing chambers with very few extra components.

•Productivity from 0.05 to 7.00 kg/hour
•One single collecting point bin, available in many different sizes
•Scalability of the process to bigger micronizers
•Very low product loss, typical yields are 99% of batch size
•Elimination of blow-back phenomenon
•Limited caking of sticky powders
•Quick and easy assembling and disassembling of the system with a limited number of clamped components
•Rapid cleaning and easy validation
•Simplicity of the whole unit
•Equipped with a skid-mounted 'Process Gas Generator' for feeding treated gas to the jet mill
•Every equipment is manufactured in AISI type 316L (EN 1.4404) stainless steel or in Hastelloy mirror polished to Ra 0.25 micron
•Special internal lining, Ptfe, Pur (Vulkollan), Ceramic, Titanium nitride, etc.

Ability to micronize very small batches/samples from 50 grams up to 7 kg/hour (J-70 model) for small production capacities with an extremely narrow Particle Size Distribution (PSD) of D99<3 micron. This is the main strength/innovation of the these machines.

Thanks to their modular design concept, these micronizers can be used for R&D as well as for small production with max. batch sizes of about 30 Kg.  These mills can very easily allow production of delicate molecules with high yields, requiring a significantly reduced amount of process gas supply to operate.

These compact and versatile units make micronization a much easier process with a low cost of operation and give your laboratory independence from third service contractors for the micronization process.  This family of micronizers has the lowest consumption of process gas compared to similarly sized units available on the market.
