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.
