The Excalibur® Commercial Dehydrator is an innovative, state-of-the-art dehydration unit.
Please take time to read this user manual before you attempt to use the dehydrator. There are several steps to
operating this unit properly and setting the sophisticated controls.
CAUTION OR WARNING
Failure to follow the instructions EXACTLY as outlined in the user manual will cause your unit to not work properly
or will cause your unit to not work at all.
Theory of Operation
Unlike an oven which maintains heat at a constant temperature, the Excalibur® Commercial Dehydrator is a
state-of-the-art dehydration unit, which utilizes the innovative technology of temperature cycling.
To begin a cycle, set a time/temperature prole on the computer controller. Start the prole. The fans and
heating elements are switched on. The fans will continue to run, until the prole is stopped.
The “AIR” temperature rises until the set point (temperature) you entered in the prole is reached. When the set
point is reached, the heating elements will switch off. The “AIR” temperature will continue to rise a few degrees
due to residual heat in the unit. and there is minimal effect on the internal food temperature by This is normal
this rise in “AIR” temperature.
The heating elements remain off until the “AIR” temperature drops several degrees below the set point, at
which time, the heating element will turn back on. The temperature will again begin to rise to the set point of
the prole. This cycling is called Hyperwave™ and is an important part of the drying process.
It is important to remember, the temperature shown on the controller is the temperature of the air at the back
of the unit. A temperature sensor can be used to check the internal temperature of the food/product being
dried if internal temperature is of concern. The food temperature and the controller’s set temperature may not
match.
CAUTION OR WARNING
All meat and poultry products should be heated to a minimum temperature of 160°-165°F prior to the
dehydration process to kill any bacteria that may be present.
