Freeze Drying / Vacuum Drying System

MicropowderdryTM SystemμPD Series

Micro Powder Dry is original and revolutional technology of ULVAC for freeze drying(lyophilizing) that renders liquids completely dry, through spraying under vacuum. ULVAC Inc also has developed a fully packaged process system for sterile production, including powder filling and capping.

Features

  • Self frozen through rapid freezing process
  • Spherical shape powder by freezing in air under vacuum
  • Homogeneous concentration of powder by freezing from liquid droplet
  • High speed drying due to larger surface area of frozen material
  • Small particle sized freeze dried powder
  • High uniformity in particle size
  • Reduced process such as milling, classifying and others

Applications

  • Pharmaceuticals
  • Health care materials
  • Foods
  • Cosmetics
  • Electronic material
