Micro Powder Dry is the original and revolutionary technology of ULVAC for freeze drying (lyophilizing) that renders liquids completely dry, through spraying under vacuum.

ULVAC also has developed a fully packaged process system for sterile production, including powder filling and capping.

Homogeneous concentration of powder by freezing from the liquid droplet.

High-speed drying due to larger surface area of frozen material.
