4. Project
Background
Preserving food is a common problem in society, which has
been around since ancient times.
Ancestors used various methods to preserve food such as
drying, salting, smoking, pickling, fermenting and chilling.
These methods slow microbial growth, allowing food to last
for several days.
Filipino ancestors preserved meat like tapa by smoking and
fish by salting.
Clay pots have natural insulating qualities and tiny pores
that allow for evaporation, which cools the water within the
pot and lowers its temperature.
The lid on a clay pot traps heat and moisture inside, helping
to maintain a steady temperature.
Overall, clay pots are an efficient way to cook food and
maintain a constant temperature due to their natural
insulating qualities, porous material, and the usage of a lid.
5. Project
Objectives
Create a system that will decrease the
temperature inside the “tapayan” to 4-10
degrees celsius using the idea of refrigeration
cycle.
Design a device that will give an access to
better preservation of foods and vegetables for
the people that can’t afford to buy a
refrigerator by incorporating the idea of
refrigerating process combining it with the
natural cooling characteristics of a clay pot.
Extend the shelf-life of food up to several days
by incorporating the refrigeration method and
pot cooling method.
7. Project and
Scope
Limitation
Develop an innovative pot cooling system for
food storage
People who cannot afford a refrigerator
Cost-efficient and practical cooling storage
solution
Up to 4 -10 degrees Celsius
Fresh food preservation for an extended period
in a clay pot.
Low cost material will be used in development
8. Project
Development
In order to come up with a specific and
correct answer to the problem at hand. The
researchers have followed a procedure.
First is thinking of a problem and gathering
information about the existing solutions
and studies that are connected to the topic.
Related articles and studies were gathered
to determine that the problem is still
existing despite existing solutions.
10. Historical
Background
Ancestors used clay pots to preserve food by burying
them near rivers, where the moist soil helped to
enhance the natural cooling characteristics of the clay
pot.
In Buenavista, Magdalena, Laguna, storage of food is
a problem for some people who cannot afford a
refrigerator or have no access to electricity.
Some people in specific areas like Sitio Sabarillio and
Sitio Chabengan use clay pots or tapayan to preserve
food and have cold water to drink.
Clay pots have natural cooling characteristics that
heps preserve food for several days.
11. Client
Requirements
Cost of the device should be ranging from Php
6,000-10,000
The device should not use an AC power, it should
use a DC power battery
The device should be easy to operate and will have
its own generating power to operate
The device should preserve the fruits and vegetable
for several days
17. Design
Options
Using the Tapayan as the main component, the
Researchers made 5 Design Options that will
put an innovation on the Tapayan to help the
natural cooling characteristics of Tapayan to
develop and preserve the food in a more
effective way.
