How does a solar cooker work?
Takes advantage of solar thermal energy
and that generated by biomass. That is, it
has components capable not only of
directing and focusing the sun's rays by
means of reflecting surfaces, but also of
employing the biogas resulting from the
anaerobic digestion of biomass to
increase heat or produce heat as a
complementary mode of thermal energy
generation.
The operation of a solar cooker depends
on two basic actions:
The reflective surface directs the sun's
rays to a vanishing poin where the heat
is concentrated.
A container is placed at the vanishing
point, where it absorbs the concentrated
heat of the sun.
Apart from that, there are several details that
are taken into account and that are essential
for the proper functioning of the solar stove.
The power of solar cookers depends on the
quality of the materials, the weather
conditions, the appropriate design and the
correct placement.
The more reflective the material, the more
power the stove will have.
RADIATION DRYING AND STOVES
The design of the container is important. It
can be made of thin aluminum and painted
black, so that it absorbs quickly the heat that
comes to it. Or it can be a dark pot inside
another glass container (for example a
transparent pan), so that the heat is trapped
inside the glass and absorbed by the dark pot.
Other elements can be added as required by
the conditions. For example in cold places or
windy days, you can wrap the pot in a plastic
bag to avoid heat loss.
STUDY APPROACH
ADVANTAGE
1 Ease of use, they do not pollute, since they
are very ecological because they do not need
electricity or fuel. There is high availability of
manufacturing materials.
2 Encourages the use of renewable energies,
which saves money in the cooking of food. It
is very accessible.
3 As manufacturing materials are often
synthetic and waterproof, the solar cooker has
a high degree of cleanliness.
4 It is a good solution in places where the
climate allows its daily use.
It is a benefit in countries and places where
energy resources for cooking are scarce or
costs too high.
ADVANTAGES OF A HYBRID SOLAR
STOVE:
11 It is used efficiently even if the sky is not
completely clear, since when using biogas as
an alternative energy system, the cooking
time is equivalent to a gas or electric stove.
12 Your parabolic solar cooker design gives
you high efficiency and energy loss.
13 It does not depend on the weather
conditions to be able to cook. it is possible to
cook during the most cloudy months or
periods of heavy rain when using the
complementary biogas system.
14 It can be used at night, either with the use
of an insulating basket which allows the
bonfires to be prolonged for cooking several
hours
COMPLEMENTARITY BETWEEN THE SOURCE OF
HEAT AND AN AIR FLOW,
The temperatures inside a solar stove can
reach up to 200 to 250 ° C. This is hot
enough to cook food, but it is a lower
temperature than conventional ovens can
reach. It takes more time to cook food
using a solar stove, so the food is brought
to the stove well before serving time. Large
pieces of food, such as roast meats, can be
cut into smaller pieces to help them cook
faster on a solar stove.
A solar stove can:
Cooking food without the need for
electricity, wood, oil or other fuel.
Pasteurize water to make it drinkable,
preventing many diseases.
Save trees and / or other resources.
Avoid contamination and have to
breathe smoke while cooking (lung
diseases).
Using the free energy of the sun is a
renewable energy.
Cooking food without having to pay
much attention or none without
burning.
Kill insects in the grains (of cereals).
Dehydrate fruits, etc.
Make refrigerator at night to cool and
even freeze water (with the same
stove).
