Problem background

The existing incubators have inconsistent temperature and will

increase the percentage of hatching failure. Thus, improvements mustbe made to overcome this problem.

Scope

Design and build various species of quail egg incubator with

automatic control of temperature, humidity and time of turningthe eggs using microcontrollers and parameters set by user.

Objective

To design experimental system for incubation and hatching eggs formore quality and effective.

To design turning egg system.

To design experimental machine that is able to control thetemperature and humidity in incubator automatically based on the

various types of quail eggs.

Continuation..

Types of incubator

Still air incubator Forced air incubator

No exhaust fan to circulate the air

flow

Reduce percentage of hatching

Some eggs did not get the right

/suitable temperature

Have exhaust fan to circulate the air

flow

Increase percentage of hatching

All the eggs are exposed to same

temperature

ContinuationEgg turning mechanism

Tilting tray Moving floor Rollers

Egss will be tilted at an

angle of 40 degrees Works fine for commercial

purposes

Suitable for chicken eggs

Eggs are laid in horizontal

floor conveyor where itwill move side by side

Widely used in small scale

incubator

Suitable for egg having an

axis of symmetry

Rollers rotated by a

moving floor Used in small scale

incubator

Suitable for egg having an

axis of symmetry

Project system


10/19

Start

Select the desired species

of eggs on display

Adjustment of temperature and

humidity be automatically

created

whether the

temperature

and humidity

consistent ?

Check hardware

No

Yes

Filling the eggs in the

incubator

Automatic control of temperature and humidity consistently

heating coil will work

depends on the temperature

conditions

Fan function depending

on humidity conditions

the motor will work 2-3

times a day

the system will be disabled until the reach ofthe incubation process

Analysis and discussion result

Egg turning system

Using pulleys and belts as power

transmission

Powered by low speed geared

motor

Eggs will be filled in the gap

barriers to prevent it overdrawn

from conveyor

15/19

Water filling system

This system will be designed automatically by using sensors

Water reservoir outside incubator will automatically supply the water at

water pan in the incubator

Ventilation system

Forced air will be streamed using exhaust fan The air will be fill the space inside incubator

convective air will flow from bottom to top

Circuit system This system will be controlled by the microcontroller

Sensor will give feed back to the controller in order to stabilize the system
