The VACUPRESS machine is an apparatus for deaerating and compacting/densifying fine-grained, light powders to reduce their volume for packaging and transport.
The VACUPRESS has been successfully used in the bulk materials industry for more than 50 years. VACUPRESS machines serve as densifiers upstream from packaging systems to reduce the shipping volume and dust formation, as metering systems or as precompactors in combination with granulators.
Treatment in the VACUPRESS machine does not alter the properties of the product; what happens is that the particles form a denser arrangement. The products can easily be converted back to their original fine powdered state.
