The drain valve is located at the front, and is used for draining the ice condenser after de-icing.
5. Operation
The freeze drying process is a balance between the heat absorbed by the sample to vaporize the ice, and the
heat removed by the condenser to convert the water vapor into ice.
It is important to remember following factors when trying to obtain efficient utilization of the freeze dryer
system.
The efficiency of the freeze drying process depends upon:
The surface area and the thickness of the sample.
The temperature of the condenser and the vacuum obtained.
The eutectic point (melting temperature) and the concentration of the sample solution.
