CHAPTER 1

INTRODUCTION

A. Background of the Study

Grilling is a form of cooking that involves dry heat

applied to the surface of food, commonly from above or

below. It is sometimes referred to as barbecuing but that

word can also mean a different cooking technique. Grilling

usually involves a significant amount of direct, radiant

heat, and tends to be used for cooking meat quickly. Food

to be grilled is cooked on a grill, a grill pan,

or griddle.  Heat transfer to the food when using a grill

is primarily via thermal radiation. Heat transfer when

using a grill pan or griddle is by direct conduction.

Proper grilling doesn’t come from propane or charcoal.

Either can be used to produce tasty results. The most

important aspect is high heat management. Getting your

grill hot enough to give that grilled flavour on your steak

without turning it to ash is an art. That’s why this new

solar powered grill has me weary. It’s not an electric

grill that runs on solar power, it’s literally a grill that

cooks with the sun. A solar heated grill can be built from

a cardboard box, tin foil, and poster board. Sunlight it’s

the reflective surface and focuses on the hot dog held in

the center. You’ll actually get some use out of it

afterwards. Some of the principles it demonstrates are:

1. Optics: focusing parallel rays of incident light through

theuse of a parabolic mirror.

2. Energy transformation: light to heat

3. Renewable energy: solar power

B. Statement of the Problem

The price of almost all commercialized or local

products continuously increasing.And this is a big

aspect to be considered in budgeting things. Some people

cannot afford to buy a grill to roast or to grill foods.

C. Significance of the Study 

This study aims to find out if an old shoe carton box

can be useful to make an alternative cooking machine. This

projectwill serve as an eye-opener for those who don’t

have a grillin their backyard who want to convert their

old shoe box carton into a hotdog grilling machine, provide

information to students and teachers with respect to

the recycling of cartonbox or old shoe box and it will

also serve as motivatingfactor for the schools or

institutions to direct their students and to further

strengthen their capabilities for developing old carton

box into a cooking grilland otherprocesses to maximize

the recycling of old carton box.Furthermore, the outcome

of the study will provideempirically based information

topolicy makers in Ecologicalrecycled Waste Management.

(RA 9003) junk cartons areusually stocked or thrown out

elsewhere .Converting these non-functional cartons doesnot

only support RA 9003 but italso opens an avenue to develop

technology in thecommunity.

D. Scope and Limitations

The study focus on grilling food through solar heat.

By using this, the people can grill food without buying

those expensive grillers. Our group want to propose a

product that is environmental friendly and can suit to the

budget that we have in our everyday life.This is a less

expensive project because all of the materials needed can

be seen inside our house. This project can really help

people who cannot afford to buy grillers.

E. Definition of Terms

For purpose of clarity, the following terms used in the

study are hereby defined.

Grill - Outdoor cooking appliance .To cook food above

Charcoal - gas or other means of heat.

Tin Foil - A wrapping substance to keep food.

Fresh Skewer - is a thin metal or wood stick used to

hold pieces of food together. They are used while

grilling orroasting meats, and in other culinary

applications.

Chapter IIREVIEW OF RELATEDLITERATURE

Proper grilling doesn’t come from propane or charcoal.

Either can be used to produce tasty results. The most

important aspect is high heat management. Getting your

grill hot enough to give that grilled flavour on your steak

without turning it to ash is an art. It’s not an electric

grill that runs on solar power; it’s literally a grill that

cooks with the sun. The Solar-Grill uses a flexible mirror

to aim the sun’s rays at the black “barbecue cup” to get it

nice and toasty. Since it’s light and easily transportable

this is a good solution for camping or even tailgating. No

need to worry about flames or smoke. Solar cooked food

makes up for that by being particularly tender and

succulent. Nothing ever burns or needs to be stirred.

Since, it uses no fossil fuels its carbon free. But it also

costs you nothing to use so you save money. A barbecue

grill is a device for cooking food by applying heat

directly from below. There are several varieties of such

grills, with most falling into one of two categories: gas-

fueled and charcoal. A small metal "smoker box" containing

wood chips may be used on a gas grill to give a smoky

flavor to the grilled foods. Although, barbecue purists

would argue that to get a true smoky flavor you have to

cook low and slow, indirectly and using wood or charcoal.

Chapter IIIMETHODOLOGY

 A. Materials/Equipment:

1. Cardboard box ( We used an old rollerblade box )

2. Aluminum foil.

3. Some masking tape. (Better touse magic tape.)

4. Grill rack and plastic wrap.

5. Pencil & Permanent Marker

6. Scissor & Black ConstructionPaper or Black Cloth

B.Procedure

1. Cut the top flap. Using the permanent marker trace a

square over the top of the box, leaving about a one to two

inch border. Cut out the box, leaving the back (top) end

attached so it becomes a flap.This top flap will become

our reflector for the sun light.

2. Line with aluminum and Black construction paper. Line the

bottom of the box with aluminum. Use nontoxic tape or glue

to secure the foil in place. Take the black cloth or black

construction paper and place it over the foil. Secure it

with nontoxic tape or glue.

3. Line lid with foil. Line the inside of the lid and

reflector with foil. Secure with nontoxic glue or tape.

4. Cover the square hole we cut earlier with the plastic

wrap and over the front of the box with the black cloth

or construction paper. This helps the box to absorb more

heat. Secure with nontoxic tape or glue.

5. Place over in the sun. Place the

grillin the sun. Angle the reflector to

where the most sunlight is reflected into

the box. Tape the pencil to where it

holds up the lid in place. Leave the box

in the sun for a half an hour to an hour

to warm up. It may take a little longer

depending on the heat and how clear the

sky is in your area.

6. Put in the food. Once it is pretty hot put the food in

that you want to cook. In researcher’s case, they

choose hotdogs. Let them cook for a couple of hours or

until they are a nice golden brown color. Check on

them every 15 minutes.
