Nano ice in granules by Freeze Granulation The formation of nano ice in the Freeze Granulation process is a key factor for the unique homogeneity of particles and binders achieved in the resulting granules. This is especially important for nanopowders, fine particles and binders where migration of these could occur during conventional drying, like spray drying. Please contact us for… Continue reading Nano ice formation in granules

Freeze drying
Spray Freeze Drying for Soft Granules by Freeze Granulation Freeze drying is an important processing step in Freeze Granulation where we sublimate the solvent (ice if water) from our spray frozen (spray freezed) granules, resulting in a free-flowing and dust-free granulated material suitable for pressing of components. Please contact us for more information and a test-granulation of your powder system.
Freeze Granulation produce flowable and crushable (soft) granules
Freeze Granulation produce flowable and crushable (soft) granules suitable for die pressing applications. Spray drying yield flowable, but hard granules which are difficult to cruch during die pressing. Please contact us for more information and a test-granulation of your powder system.
Diamond powder processing
Freeze Granulation is today being used by market leaders in manufacturing of diamond tools like diamond wheels using PCD – Polycrystalline Diamonds. Homogeneous distribution of the active component, diamond particles, in diamond wheels is very important for the cutting performance and tool life. By using Freeze Granulation you will bring your slurry, with diamonds, in… Continue reading Diamond powder processing
Needle-free ballistic powder delivery
By applying Freeze Granulation you will be able to make microparticles with high insulin loading (nanosuspension) suitable for needle-free ballistic drug delivery. The resulting granules are homogeneous and robust with a diameter of around 50-150 µm, with a narrow size distribution and a high content of insulin.
LED photoluminescence granulation
Freeze Granulation is today used for commercial production of homogeneous granules for the production of oxides used as a ceramic phosphor plate for white illumination in LED Lighting. By using Freeze Granulation of the powder and binder mixture, compared with spray drying, it is possible to manufacture a homogeneous phosphor plate with optimal properties for… Continue reading LED photoluminescence granulation
How to avoid doughnut or donut shaped granules?
By using Freeze Granulation – Spray Freeze Drying – you will be able to avoid donut-shaped granules. — 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 system.
Powder Compaction of Freeze Granulated Powders
For optimal powder compaction in for ex uniaxial die pressing of metal or ceramic powders, it is important to have homogeneous granules where the binder and fine particles are well distributed in each granule. By using Freeze Granulation you can achieve this.
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?
What is the meaning of homogeneous granules?
Freeze Granulation for optimal granule properties compared with spray drying. Homogeneous granules with no void formation, no migration of fine particles or binders, and no formation of hard dry shell.
