Protein aerosol powders
Freeze granulation, as opposed to spray drying, has been shown to produce protein particles with light and porous characteristics, which offered powders with superior aerosol performance due to favorable aerodynamic properties, suitable granulation technology for protein inhalation powders.
Granule homogeneity
Migration and segregation of the constituents that is common in other granulating processes such as spray drying is avoided in Freeze Granulation. By instant freezing of small droplets critical ice crystal growth is avoided. The freeze drying where the liquid medium is sublimated ensures homogeneity preservation, limited oxidation and soft bonds within the granules. This provides… Continue reading Granule homogeneity
Thermal spraying
Homogeneous thermal spray powders, for forming thermal spray coatings, can be made by Freeze Granulation. The homogeneity of the spray powders is very important, not only for composite spray powders and by using FG you will keep the homogeneity throughout the process.
Technical specification lab-scale freeze granulator (LS-2)
PowderPro AB provides equipment for Freeze Granulation in two versions, LS-2 (see photo) and LS-6. The maximum granulation capacity of LS-2 is 2 litres slurry per hour and for LS-6 6 litres slurry per hours that typically correspond to ca 2 and 6 kg dry powder respectively. LS-2 and LS-6 consists of a slip container… Continue reading Technical specification lab-scale freeze granulator (LS-2)

Deagglomeration of nanoparticles and other submicron powders
By applying Freeze Granulation on your agglomerated nanoparticles or submicron powders you will be able to deagglomerate them forming a homogeneous well-dispersed particles or mixture of particles. Please contact us and we will further discuss the opportunities with Freeze Granulation on your powder system and read more on technology and we propose a Granulation Test of your powder… Continue reading Deagglomeration of nanoparticles and other submicron powders
Can you make spherical granules?
Yes, with Freeze Granulation it’s possible to make spherical, homogeneous and dust-free granules with optimal flowability which is critical for automatic uniaxial pressing of for ex ceramics and metal powders. You can expect spherical and homogenous granules of powders in terms of distribution of particle size and other possible additives you want to use. The granules… Continue reading Can you make spherical granules?
