ULVAC Solutions for µPD (Micro-Powder Dry) system
|
"Leading Edge Process for Lyophilization" |
|
The powder that is obtained using conventional lyophilization technologies, such as a freeze-drying and a spray-drying, presents problems like differences in concentration, low solubility, and inhomogeneity.
We, ULVAC, have solved those problems, utilizing the technology that renders liquids directly dry. Then, we also incorporate a fully packagedprocess system for sterile production including powder filling andcapping. Apply to not only pharmaceuticals, but also food processing,fine chemicals and electrical materials.

Basic Principles of µPD

Advantages in Using µPD System
|
[1] Small particle sized and homogeneous powder production |
High speed drying due to larger surface
area of frozen material causes a very
sharp profile of particle size distribution
and no concentration gradient of
powder. It means that these particles
have high uniformity in particle size and
very homogeneous concentration of
powder by freezing from liquid droplet. |

Market
One of the most important application utilizing µPD is the sterile pharmaceutical production.
Turn key system of µPD has been constructed aiming at advance into Global Market.
Those technologies which contribute to novel pharmaceutical production using extremely small sized powder, are applied for not only conventional freeze dry processes(Lyophilization)but also general splay-dry and vacuum-dry ones.
The µPD technology is also applicable for Health care materials, Foods, Cosmetics, and Electronic material productions as well as pharmaceutical one.
