vrieco-nauta conical vacuum dryer
heat energy is basically transferred into the product through a jacketed vessel wall causing solvents or moisture residues to evaporate. a rotating screw orbits along the vessel wall and helps the vapours to escape to the surface, at the same time providing a frequent exchange of particles in contact with the heated surface.
a vacuum system keeps the vessel under constant vacuum and removes vapours from the vessel. entrained dust particles are separated in a filter mounted above the dryer.
features / benefits
fast drying times as the mixing screw continuously circulates the product from the bottom to the top of the vessel improving heat transfer conditions.
final moisture after drying is possible down to 0%.
low energy consumption.
gentle to product.
quick and efficient removal of vapours.
recovery of pure solvents is possible.
dried solids are suitable for direct use.
easy to clean.
particularly suitable for final drying of powders, granules, pastes and slurries especially when they are brittle and/or temperature sensitive.
