Design And Construction Of An Electric Gas Cooker With Temperature Control Oven

ABSTRACT

This work is on an electric gas cooker with temperature control oven. An electric gas cooker is an electric and gas powered cooker for heating and cooking of food. An electric gas cooker has two different heating place, one for electric powering and the other for gas. An electric cooker  is powered by electricity, while gas cooker is powered by gas. A gas cooker uses natural gas, propane, butane, liquefied petroleum gas or other flammable gas as a fuel source.

An electric cooker used to incorporate with an oven. An oven is a thermally insulated chamber used for the heating, baking or drying of a substance and most commonly used for cooking. An electric cooker and oven operates with the same power source. There will be knobs to determine the temperature of the cooker and the oven. The temperature of the oven is to be controlled automatically using a temperature sensor known as thermostat or theorist.

1.0                                                        INTRODUCTION

The idea behind the design and construction of this system is to make available or alternative means of cooking food, baking and roasting food for household or industrial purpose. This goes a long way in helping to curb the problem frequently encountered problem-spoil food, which is cause as result of inadequate boiling and roasting of food.

An electric gas cooker is an electric and gas powered cooker for heating and cooking of food. An electric gas cooker has two different heating place, one for electric powering and the other for gas. An electric cooker  is powered by electricity, while gas cooker is powered by gas. In cooking, a gas cooker is a cooker/stove which uses natural gas, propane, butane, liquefied petroleum gas or other flammable gas as a fuel source.

An electric cooker used to incorporate with an oven. An oven is a thermally insulated chamber used for the heating, baking or drying of a substance and most commonly used for cooking. An electric cooker and oven operates with the same power source. There will be knobs to determine the temperature of the cooker and the oven. The temperature of the oven is to be controlled automatically using a temperature sensor known as thermostat or thermistor.

1.1                                                            OBJECTIVES

This project is undertaken to

(1)    Compare the various ways used in the construction of an electric gas cooker with temperature control oven.

(2)    Disclose the different types of process in the manufacturing of an electric oven and also an electric gas cooker in the past in comparison to the modern days method.

(3)    Exploit the local facilities available in the construction of the oven as against imported ovens.

(4)    To exhibit the usefulness of a oven in the economy and technology growth of the nation.

(5)    To know the convenience in the use of alternate power source for operation of ovens.

(6)    Discover the basic principle involved in the design, installation and maintenance an electric gas cooker and  oven.

1.2                                                IMPORTANCE OF OVENS

In actual analytical enunciation an oven is an enclosed chamber in which things are heated or cooked with various sources of power.
Its importance borders around its function, which are as follows;

(i)    It is used to meet the everyday basic need of cooking, (baking, toasting, gritting, toasting) of food materials for human consumption.

(ii)    Ovens are used for heat treatment of substance in laboratories and industries.

(iii)    Also as a means of preservation by heat application to perishable materials (organic and inorganic) in general.

(iv)    Sterilization of instruments and equipment for industrial use is done by heat application using oven.

(v)    Expelling of moisture content to a required measure in some substance is also done using oven.

(vi)    Early manufactured ovens where used as a source of room heaters during cold weathers in cold climates.

Other importance boarding around its energy source is that the use an alternative source of energy when either fossil fuel or electricity is not available.  This can be relatively save cost when necessitated.

1.3                                                 LIMITATIONS OF OVEN

Disadvantages in the use of ovens:

(i)    Cleaning and repair is a difficult and time- consuming endeavor.

(ii)    Expect for mass production singular construction is relatively expensive to produce.

(iii)    If precautions are not well carried out, it can result in fire hazard, which is dangerous to life and properties.

(iv)    Because an oven provides heat for one or more areas, the temperature may vary in different areas of the oven.

(v)    Oils and moisture collected on metal surface can end up trying to rust the metal coating if not clean regularly.

(vi)    It is expensive to operate in high volume operations.

(vii)    Speed seems to be the key factor and time taken to get to required constant temperature can be wastage of time.

(viii)    Access to internal component n case of adjustment and maintenance is tasking as it requires an entire disassembling.

(ix)    In case of mechanical faults resulting from shut down, an entire disassembling and requires is required.

(x)    Due to its function by heating, there is always a premature wear or mechanical failure of
