Solar Box Cookers are ovens that use the sun to heat and cook food. These cookers can reduce farmer’s reliance on trees while still letting people make hot food.

Working of A Solar Box Type Cooker

Solar

The black surfaces on the inside of the oven capture and transforms the sun's energy into a form that cannot escape the oven chamber. When a Enolar Sun Oven is focused in the sun, the interior of the Oven is heated by the sun's energy. Direct and reflected sunlight enters the oven chamber through the glass door. It then turns to heat energy when the balck inner-shell and levelator absorb it. This heat input causes the temperature inside the oven to rise until the heat loss of the oven is equal to the solar heat gain. The light energy absorbed by dark pots and the oven's dark interior is converted into longer wavelength heat energy. Most of this longer-wavelength radiant energy cannot pass back out through the glass, ensuring more efficient cooking. The demands of massive population growth, and inefficient conversion of wood to charcoal, have outstripped the third world forests ability to regenerate. The ecological effect of wood fuel is burdensome and has a far-reaching negative global impact. These global trends will lead to environmental de-stabilization leading to deforestation, and global warming. Science strongly supports the fact that deforestation for agricultural and fuel use is changing weather patterns, causing soil erosion, and depleting plant and animal life. Sun Ovens offer a powerful solution to the effects of deforestation, and have an enormous positive impact on the every day life of millions of people in under-developed countries by improving their nutrition, health, and quality of life.

Features

Helps You Harness the Power of the Sun1234
One source of power that never fails is the light of the sun. Whether you're dealing with a power outage, or just plain conserving energy, the Enolar Sun Oven can cook anything that can be baked in a conventional oven. It lets you harness the power of the sun to cook without fuel.

Lets You Create Your Favorite Recipes
With the Enolar Sun Oven you can cook almost anything; breads, cakes, pizza, vegetables, poultry, fish, meats, casseroles, grains, just to name a few.

Provides High Cooking Temperatures
Sun Ovens reach temperatures of 360 F to 400 F, which is more than sufficient to bake, boil or steam your favorite food wherever you happen to take your Enolar Sun Oven.

Makes Food Taste Better
Sun-Baked foods stay moister and have less shrinkage than the food cooked using the conventional oven. Also, with the Enolar Sun Oven there is never any burning or scorching to ruin a meal.

Is Totally Safe
Because of the unique way the Enolar Sun Oven operates, there is never a danger of fire.

Is Ruggedely Built
The Enolar Sun Oven is not a toy. It is a serious appliance that is made for years of trouble-free use. Each Sun Oven is constructed with a strong Aluminium case that is both durable and easy to clean. It uses Aluminium Foiled reflectors and a tempered glass door to retain the sun's powerful heat. The Sun Oven features an easily adjustable, self-contained levelling leg to maintain the ovens maximum exposure to the sun, while a built-in levelator keeps foods level inside the oven to avoid spills.

Is a Great edge against Power Interruptions
With a Enolar Sun Oven, you will be prepared for any interruption to traditional power sources. You will be able to cook any kind of food as well as boiling water. You can enjoy the peace of mind of knowing that as long as there is sunshine, you will have all the power you need to cook your meals.

Description

These are usually concave disks that focus the light onto the bottom of a pot. The advantage is that foods cook about as fast as on a conventional stove. The disadvantage is that they are complicated to make, they must be focused often to follow the sun, and they can cause burns and eye injury if not used correctly. Some of these concerns have recently been reduced.

Major Components

The major components of the cooker will be as below :

Reflecting Bow : It is a parabolic dish made of reflecting sheets supported on suitable rings for holding them in a fixed position. The sheets are joined together in such a way that they automatically form the parabolic shape. The structure and frame of the bowl are made strong so that the reflectors do not get deformed while turning it in various directions.

Reflector Stand : The reflector stand is made of mild steel having powder coating for better durability. The stand is designed in such a way that the reflector could rotate 360 degree around the horizontal axis passing through the focus and the centre of gravity. It should also be able to rotate around the vertical axis so as to adjust the cooker in the direction of the sun.

Two Box Packaging – One Reflector and other steel members

This is a Solar Concentrator type solar cooker (aperture area 8 sq. m.). This is an efficient design of solar cooker, where temperatures of over 300°C can be reached. This contributes to speedy cooking. There is no need to wait for hours after keeping the utensils in the sun. Our cooker uses utensils containing thermic fluid so as to transfer the heat into the kitchen cooking area.

Our Solar Concentrator type solar cookers are easy to install, operate and maintain. This model is suitable for urban, rural, tribal areas for the use in households, community kitchens, hotels, hostels, remote campuses and the like.

This system is suitable for cooking food for 80 -100 persons daily.

Major Components

The major components of the Scheffler dish cooker will be as below:

Reflector : It is part of a parabolic dish made of reflecting sheets supported on suitable rings for holding them in a fixed position. The sheets are joined together and tied on the support in such a way that they automatically form the parabolic shape. The structure and frame of the bowl is made strong so that the reflectors do not get deformed while turning it in various directions.

Reflector Stand : The reflector stand is made of mild steel having proper painting for better durability. The stand is designed based on the latitude of the place where the cooker is to be installed. It supports the reflector and allows it to rotate around the polar axis. The polar axis is the axis parallel to the axis of rotation of the Earth.

Tracking Mechanism : The tracking mechanism works with the help of a counterweight, which is raised every morning as we manually make the reflector face the sun. Once the weight is raised, its downward motion is controlled with the help of a pendulum clock mechanism, which controls its angular speed to one revolution per day, which is the speed of rotation of the earth about its own axis.

Secondary Reflector : This is the reflector placed below the vessel inside the kitchen platform. It reflects the sunrays concentrated on to its surface by the main reflector, which is automatically tracking the sun. The secondary reflector is made of aluminum foil pasted over a structure, as we need to replace it every now and then since it gets dirty due to spilling of food while cooking.
