PowderProAB provides equipment for freeze granulation in two versions, LS-2 and LS-6with a maximum granulation capacity of 2 or 6 litres slurry per hourrespectively. Possibilities to process up to 20 litres per hour exists with thePS-20 model to be customized upon request. We also provide the freeze dryerGT-2 with trays.
LS-2 PS-20 GT-2
Thelab-scale granulator LS-2 has a capacity of about 2liters/hour. consistsof a slip container with a stirrer, a pump for the slip, a spray nozzle, aregulator for compressed air and an insulated chamber for spraying and granulecollection.
The has the capacity of 20liters/hour corresponding to 50-100 kg/8h shift depending on the solids loadingin the slurry.
TheProduction Granulator, PS-20, has aproprietary spraying chamber with continuous liquid nitrogen flow and isadditionally equipped with an apparatus frame, a circulation pump for liquidnitrogen, a device for continuous removal of frozen granulate and regulation ofthe N2-liquid level.
Instant freezing ofsprayed suspension drops and subsequent freeze-drying preserve homogeneity. Nomigration, weak inter-particle bonding and minimum oxidation of metals ornon-oxides.
