were adjusted at the beginning of the process. When the process is
complete an audible signal will be heard and the display will read “Complete”.
The following is a graphic representation of how the freeze dryer operates. The numbers to the left represent the
mTorr pressure and the amount of cycles are represented below. The amount of cycles will vary depending on the
moisture content and cellular structure of the food. Different foods will have more or fewer cycles than indicated.
Also, Cycle times will vary depending on the type of food that is being dried, age of vacuum pump oil and cleanliness
of vacuum pump. In order to achieve optimal freeze-drying, assure the vacuum pump is working properly.
*mTorr pressures may vary slightly from those in the graphic representation.
