Lyophilizer

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.

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
