Design And Construction Of An Electrical Charcoal And Gas Oven
Complete Design And Construction Of An Electrical Charcoal And Gas Oven Project Materials (Chapters 1 to 5):
The aim of this project is to design and construct a portable combine Charcoal, Electric and Gas baking oven with a temperature regulator/sensor. The major reason for undertaken this project is to design and construct a portable combine oven with three mode of heating, and also to improve the performance of already existing ovens that have been crippled by lack of constant gas and power supply.
This study deals with the design, construction and performance evaluation of a charcoal, electric and gas oven. The components of the oven includes the oven cabinet, insulated wall, control box, electric heater, charcoal/gas burner unit, heating elements, electrical accessories and 1.5mm thick mild steel plate used for the design of the outer and inner cabinet of the oven.
In this work, test was carried out which shows the amount of heat supply by the three energy source at a specified period of time. The results obtained shows that gas produces greater amount of heat supply for a given time range of 22mins when compared to the other sources of energy. The heat transferred through the walls of the oven is 11.48Joules, and the number of loaves of bread that can baked in a given period of time at a constant temperature of 1450C.

INTRODUCTION
1.6 Background of the Study
In recognition of the fact that the country has been economically and technological under developed and has been economically dependent on the first world countries for survival and in an effort to proffer solution to these challenges, the Structural Adjustment Programme(SAP) was introduced by the Babangida administration in 1986. This place embargo on the importation of some goods as a means of inspiring our people to develop indigenous technology. On the part of our engineers and technologists, the need for our technological emancipation was brought to sharp focus and thus this fuel the zeal to bring about the much needed technological breakthrough.
It has been realized that no country of the world, most especially the advance countries of the world, are oblige to transfer their technology. This leads to technology dependency on these nations from time to time, when the need arises.
It is important therefore to point out, based on the realization of the above fact, significant achievement have been made in the technological field and the wide gap existing thereof has been greatly bridge. Engineers and Technologists have been able to put all their efforts mentally into research and engineering designs which facilitate productivity.
These underlying facts, have acted as an impetus towards the design and construction of a Charcoal, Electric and Gas baking oven with a temperature regulator. The fabrication of the baking oven makes use of available local materials.
One of the major developmental goals of a nation is to ensure that her inhabitants enjoy a good standard of living at relatively low and affordable cost. Undoubtedly, this goes a long way in creating a buoyant and vibrant economy. To achieve this entails embarking on the manufacture of products of good quality that satisfies basic home needs.
1.2 Statement of the Problem
The preservation of perishable commodities particularly food stuffs is one of the common use of an oven. The other uses are to effect heating, drying and baking of consumable materials. In order to serve the above function and meet the service needs of catering, schools, resort centers and the domestic home front, it becomes imperative more than ever before to design and fabricate a compact, functional and easy to maintain baking oven.
1.3 Aim and Objectives
The aim of this project is to design and construct a portable combine Charcoal, Electric and Gas baking oven with temperature regulator/ sensor. To achieve the aim of the project, the following objectives were employed:
1. To design and construct a portable combine charcoal, electric and gas baking oven with temperature regulator/sensor.
2. To design and construct an oven that could enhance the working conditions of the bakery staff that were previously exposed to dangerous smoke and intense heat emission from the existing baking oven.
3. To design and construct an oven that could improve on existing baking oven.
4. To design and construct an oven that could reduce the baking time and better quality.
1.4 Significance of the Study
The importance attached to the design/fabrication of a combine electric, charcoal and gas baking oven is to accomplish a fast heating and drying system without burning the bake food.
The design and construction of this baking oven affords the end – user, the use of alternative energy sources to bake various forms of confectioneries.
Lastly, the oven offers some unique features such as portability, ease of maintenance and reduced cost of purchased when compared with an imported oven.
1.5 Scope and Limitation
There are various types of oven dryer which are:
i) Industrial oven dryer
ii) Solar oven dryer
iii) Domestic oven dryer
The design scope of this heating and drying system is specifically for domestic use or application as well for petty – commercial purposes.
The limitation of the design of the equipment is based on its specification in terms of temperature, capacity and areas of need to this end, the equipment is not suitable for industrial used where a bigger volume of oven dryer with large specification are ideal.
