Freeze drying is a 3-step process. It involves selecting the type of food that you want to dry and freezing it. Next, the food is placed in a strong vacuum (make use of a good vacuum food sealer). Here, the ice crystals in the food sublimate turn directly into water vapor rather than passing through the liquid state.

Choosing the right condenser - Chemistry Stack Exchange

In a Graham-type condenser (the right condenser in the picture below), the water flows around a tube (whether straight or coiled) that contains the vapor/condensed liquid. ( picture source) The Graham-type condensers clog (or flood) more easily since they have a more restricted path for the liquid to return to the pot.
