Lyophilization. Means "made solvent loving", that's what the books say anyway. This is a long time since your question, but I only found this site today.
Freeze dryers usually have a two-stage rotary vane vacuum pump to reach about 0.1 torr or better at final vacuum when the product is dry.
The condenser should be at about -30 deg C and the product at about -50 deg C. The condenser grabs the water vapor to prevent it from contaminating the pump.
Hope your project is still going forward.
