PRINCIPLES OF OPERATION
Microwaves are a type of radiation energy. Just like radio waves, visible light
and infrared, the microwaves are part of the electromagnetic spectrum, i.e., it
is a form of electromagnetic radiation. They are classified as non-ionizing
radiation, because, unlike x-rays, Alpha, Beta and Gamma rays, its effects are
strictly thermal and therefore do not alter the molecular structure of the item
that is being irradiated.
The basic principle of microwaves is to cook by molecular vibration. They
penetrate the food surface in a depth that ranges from two to seven
centimeters, heating the molecules of water and fat by making them vibrate.
The heat is transmitted to the interior of the food by thermal conduction,
demystifying the idea that the microwaves cook food from the inside out.
The
Copa Express
works through the association between microwaves and
hot air directed towards the food. The variables in the operation consists of:
a)
Operation time.
b)
Chamber temperature.
c)
Microwaves power.
d)
Air speed.
Each recipe operation can be programmed with up to eight steps and each of
them can have the variables mentioned above.
Temperatures
: The preparation times are short and so are the steps. The
temperature variation between steps will not be observed by the unit.
Normally, the temperature used is the same temperature as the preheating
set point.
