4 COPA EXPRESS TECHNOLOGY
The Copa Express oven uses a combinaon of heang for high-speed forced
air convecon and microwave energy to heat forced food more quickly than
the convenonal methods.
The figure below illustrates the steps involving the technology:
12
Magnetrons generate energy through microwaves, which uniformly heat
the water molecules of the food;
Internal heang resistors transfer heat energy to circulang air;
The Srrer distributes the microwaves evenly;
Impinged air is directed toward food;
Inferior resistors help the heat transfer within the chamber;
The Catalyc Converter converts the volale organic compounds into
carbon dioxide and water (CO2 and H2O);
The blower motor makes the air circulate at high speed.

5 OPERATION PRINCIPLES
Microwaves are a type of radiant energy. As well as radio waves, visible light
and infrared, the microwaves are part of the electromagnec spectrum, i.e., it
is a form of electromagnec radiaon. They are classified as non-ionizing
radiaon, because unlike x-rays and 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 vibraon. They
penetrate the food surface in a depth that ranges from two to seven
cenmeters, heang the molecules of water, fat and sugar by making them
vibrate. The heat is transmied to the interior of the food by thermal
conducon, demysfying the idea that the microwaves cook food from the
inside out.
The Copa Express works through the associaon between microwaves and
hot air directed towards the food. The variables in the operaon consist of:
Each operaon recipe can be programmed with up to six steps and each of
them can have the variables menoned above.
Temperatures: The preparaon mes are short and so are the steps. The
temperature variaon between steps will not be observed by the unit.
Normally the temperature used is the same temperature as the cook cavity
set point.

Microwaves power.
Air speed.

c)
d)
14
Microwaves: The microwave is adjustable between 0% and 100% for each 30
second fracon. For example, the microwaves in a one-minute recipe with
microwave programmed at 50% will run for 15 and stop for 15 seconds. Then
they will energize for another 15 seconds and stop for the remaining 15
seconds. In 1 minute, they will act for a total of 30 seconds. The microwaves
heat the food internally and do not require a specific mean to propagate.
Microwaves are reflected by metals but will penetrate glass, plascs, and
ceramics. The microwaves penetrate food and become aracted to sugar, fat
and water molecules.
The use of plasc or paper containers is forbidden because they will burn
inside the oven because of the heat.
Operaon Time: The food heated by microwaves occur from the outside in
and the penetraon level will vary depending on the type of food. Therefore,
you should relate the preparaon me to the food composion, the quanty
of food processed, as well as its density and thickness. The larger the food
amount (quanty or density), the greater the me or percentage will be
needed for the microwave to take effect.
Hot Air Speed: The hot air can be adjusted between 10% and 100% speed.
The hot air is controlled by a blower motor which will envelope the food.
The higher the air speed, the more likely it will be to burn the product on
the outside.
The higher the air speed, the more it will affect the texture and crispness of
the product.

6 RECIPES CREATION
When creang a recipe, all the variables menoned earlier should be
considered. The microwaves and the air speed are the crical factors for a
successful preparaon.
To get faster results in the recipe creaon, we suggest beginning
programming at 1/10 of the total me of preparaon used in a convenonal
process.
The effect of microwaves is more efficient at the beginning of the processes.
For frozen products, create a recipe with two or three steps so the food will
thaw at the beginning and the desired crispness and product presentaon are
achieved toward the end of the process.
Later, combine the air speed variaons to reach the desired crispness and
color. Remember, the air also transmits heat to the food so keep that in mind
when seng blower percentage. The food's weight, size, and shape are
crical when seng the total cook me.
The following informaon is crical when creang a new recipe.
The inial temperature of the product will change the desired results if not
considered (e.g.; frozen, cold, or room temperature).
The size and/or weight variaon of the poron of product will also play a
crucial role in determining the correct sengs.
Only use containers approved for a microwave oven to prevent any
damage and that the product gets properly cooked.

9 CONCLUSION
We emphasize characteriscs necessary for the professionals that operate
these equipments: Responsibility, Iniave and Creavity.
Responsibility appears to be a tool that incorporates innovaon and
technology, and that is an investment that should give the return compable
with the needs of the instuon where both man and machine will work
together. Ovens must be operated with cauon and care to provide best
results.
Iniave is necessary when an opportunity is given to operate such a great
tool as a Práca oven. The operator can extract opmal equipment
performance and adapt to the oven.
Creavity must be possessed by the professionals who are willing to master
the oven as a tool. Nothing is beer than human creavity and those who
have it are beer prepared to develop their own skills and recipes. se who
have it are beer prepared to develop their own skills and recipes.
