The Design And Fabrication Of A Manual Popcorn Frying Machine

ABSTRACT

The manual popcorn machine is a device for preparing especial popcorn for the human consumption. The device in produced to help the masses to be self valiance in this is of down trodden economy. This project work is divided into five chapters, chapter one; the introduction discusses the relevance of the project work, problems it is meant to address its importance, scope and limitation and definition of terms. Chapter two comprises the design and construction, component and fabrication. Chapter three brings to the assembly, principles of operation and control of the machine. Chapter four highlights about the various safety rules project cost evaluation and investment opportunity. Chapter five discussed on insertion and testing recommendation and conclusion together with references and bibliography.

CHAPTER ONE

1.1      INTRODUCTION

Popcorn is from a special type of maize unlike other types of corn which pops when heated. The popcorn preparation has long been in practice in Nigeria. It usually required a heating source (stove, fire wood), a frying pan with spoon as the stirrer. It was first discovered and used by the early Americans. Popcorn was introduced to the Western world by Christopher Columbus in the 15th century. The kind of popcorn most people pop in their microwave is the Zea mays. Zea mays everta has a certain amount of moisture content, a strong pericarp that does not allow moisture to escape very fast as other corn when heated. Consequently, a popcorn machine, which is generically used for the purpose of making popcorn for human consumption is essential. Most popcorn machines use gas, some use electricity, while some use the solar as sources of energy. The merits and demerits of these sources are observable in the production rate of the various machines, which in turn depends on the intensity of heat as well as the power source. The objective of the project, therefore, is to design and produce a manual popcorn machine that will enhance popcorn production, using local raw materials.

1.1 BACKGROUND OF THE STUDY

Nigeria’s economy has suffered a terrible setback over the year the common man finds it difficult to make for his livelihood, some people take pop-corn as one of their favorite food especially bachelors spinsters who can take pop-corn as super, breakfast and even lunch.

The University and Polytechnics graduate no longer find good employment thereby embarks on self-employment by constructing popcorn machine to meet their needs.

This unemployment constitutes the economic depression of our nations. The popcorn-making machine in constructed with locally made materials at a reduced cost. The design, construction and fabrication of the machine i.e. not in any known text at the moment, the project group therefore faced design, construction and fabrication problem.

1.2      PROBLEM STATEMENT

In most of the country such as Nigeria where electricity bill is of higher rate, consumers of electricity looks for means of reducing cost of bill by avoiding the use of some appliances on the electricity, one of the means is by using manually operated popcorn machines. However, this machine is designed and produced with the sole aim of solving the above problems thereby improving efficiency during operation.

1.3      OBJECTIVE OF THE DESIGN

1. To eliminate the use of electrical popcorn machine.
2. To build a simple pop corn maker

iii.        To achieve mass production.

1. To produce popcorn at a reduced cost.

1.4 SCOPE AND LIMITATION

This project covers design, construction fabrication and operation of the manual operated popcorn producing machine. A gas cylinder or kerosene stove can be used as the source of heat supply.

1.5 IMPORTANCE OF THE PROJECT

The project will serve as a means of employment to mechanical engineering graduates when properly carried out. Some government can longer guarantee her citizens already made employment. The present economic situation in this country calls for self-reliance. The young technological engineer can embark on the production of the manual operated popcorn-producing machine on low scale and when buoyant enough can embark on large-scale production. This project serves as a medium of enriching our knowledge of designs and constructions techniques, since it embraces practical and research operation. Thirdly, it will provide employment for the fulltime unemployment house covers. Young men and women who have attended the age of gainful employment from the government. Thus included graduates, young school leavers etc. This will provide means of revenue and livelihood, thereby helping to correct societal ills that is prevail our society.

Finally, this project is also relevant to the technology advancement of the nation. It could be exported to the neighbouring countries thereby serving as a source of foreign exchange earnings for the nation.

1.6 DEFINITION OF TERMS

Stirrer: This is the rod attached to the gear of the machine that is rotating and turning the corn in the pot.

Design Drawing: It is a drawing or outline from which something can be made.
