Sc01 1800 Watts Power on Sunny Day for Cooking Rice and Boil Water Parabolic Solar Cooker

Parabolic Solar Cooker SC01

Introduction

In areas where sunshine is plentiful and conventional fuels are expensive, like the
coast or the sierra of Peru, the solar cooker is an ideal complement to a regular stove.
It is cheap, easy to use and requires no fuel. The cooker works by concentrating the
power of the sun onto a small area in which a pot or other implement is placed. Under
strong sunlight, 5 liters of tap water can be brought to a rolling boil in about 20
minutes.

The solar cooker SC01 consists of 3 main parts. A parabolic reflector serves to
concentrate more than one square meter of sunlight into an area about 17 cm in
diameter. The control arm allows the reflector to be set facing the sun and holds the
pot at the focal point regardless of the reflector tilt angle. The stand holds the other
two components together and allows the cooker to be rotated to follow the sun as it
moves across the sky.

A parabolic is used quite differently than the solar box cooker or solar panel cooker,
mainly because it functions more as a stove top burner than an oven.
A solar parabolic cooker can reach extremely high temperatures, very quickly thus
producing the possibility of burning the food if left unattended for any length of time.
But if used properly the parabolic will produce great cooking results and replace the
need to turn on your stove top kitchen range burners.

Description

The "Solar Cooker SC01" is a mid size parabolic designed for most efficient
cooking results.
The solar stove SC01 has a diameter of I .5 meter, which produces a high output of
energy (heat) for very efficient cooking, yet is not too large in diameter that one
would have much trouble reaching the cooking plate.
The focus point of the sun's rays comes together at about thirty inches from, and
above, the middle of the parabola.
Each of the six rigid, molded steel panels that form the parabola is covered with an
adhesive backed reflective aluminize which is quite durable, yet easily repaired or
replaced if ever damaged or worn. The reflective film on this solar cooker is the key,
or means to the parabolic being able to concentrate the energy from the rays of the
sun.
The parabolic is supported by a circular stand (base) and has an easily adjusted crank
extension arm to move the elevation tracking of the parabolic up and down, and the
whole cooker swivels on its base, allowing for side to side tracking of the sun.
Unlike the solar ovens and panel cookers, there are no darkened pots that come
included with the "Solar Stove" parabolic cooker, because in reality there is no need for a "special"
pot or pan.

Installation
1. Select a open flat ground. Place the 6 pieces of steel plates facing ground(see the
picture). Assemble the plates together with the M6 screw and nut. Take care of
the reflecting film. The third hole of each plate is to assemble the circular stand
2.Install the circular stand to the plate by M6 screw (the third hole of each plate)
3. Assemble the all the bracket, pipes on to the circular stand

Daily use
1. Place the assembled cooker under the direct sunlight.
2. Use a cast-iron or some other type of black cooking pot pan. Any other color
might reflect the light and that's not what you want. The black absorbs the light
and brings the temperature up in the pot/ pan. Put in food to be cooked.
3. Put your food into the pot/pan.
4. Adjust the expansion pipe to let sunlight Focal spot fall just under the bottom of
the pot.
5. The solar cooker is turned towards the sun and left until the food is cooked.
Unlike cooking on a stove or over a fire, which may require more than an hour of
constant supervision, food in a solar cooker is generally not stirred or turned over,
both because it is unnecessary and because opening the solar cooker allows the
trapped heat to escape and thereby slows the cooking process. If wanted, the solar
cooker may be checked every one to two hours, to turn the cooker to face the sun
more precisely and to ensure that shadows from nearby buildings or plants have
not blocked the sunlight.

Daily Care
The solar cooker is very easy to take care of and maintain.
With most solar cookers the majority of maintenance will be keeping the reflective
panels clean, usually free of dust, which is easily accomplished by using a soft rag to
clear or wipe it clean with a parabolic solar cooker there is always the possibility of
splattering of food, liquids or grease on the reflective panels which is why one should
use deep pots or pans with lids to help limit splattering. If one should have
grease splatters it is best to clean the panels as soon as one has finished cooking, and
you can best accomplish this by heating a pot of water with a few drops of dish
detergent then softly wiping the panels with the rag and hot soapy water. After
doing this use some clean water to rinse the panels and then dry the unit with a soft
dry rag to prevent water spotting.
