The electrical 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 are of down trodden economy using locally available material.
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 deign and construction, component and fabrication. The various types of heating elements and stirrer and then operation are discussed.
Chapter three brings to the assembly, principles of operation and control of the stirer.
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

1.0                                                        INTRODUCTION
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.

1.1                                         BACKGROUND OF THE PROJECT
popcorn maker is a machine used to pop popcorn. Since ancient times popcorn has been a popular snack food, produced through the explosive expansion of kernels of heated corn (maize). Commercial large-scale popcorn machines were invented by Charles Cretors in the late 19th century. Many types of small-scale home methods for popping corn also exist.
Commercial popcorn machines are commonly found in movie theaters and carnivals, producing popcorn in a pan of hot oil, which has approximately 45% of its calories derived from fat. Hot air popcorn poppers appeared for home use in the late 1970s, which produce popcorn with only 5% of its calories derived from fat. The majority of popcorn sold for home consumption is now packaged in a microwave popcorn bag for use in a microwave oven.
Part of the "design" of popcorn is the locally made method used to pop it. The dry method consists of putting the unpopped grain in a basket or wire cage, agitating it over a heat source like the campfire or coal stove, allowing the corn to pop, and seasoning it with butter and salt. In the wet-pop method, corn is placed in a container with a solid bottom. Oil is added (either before the corn or poured on top), and the oil helps to distribute the heat and cause more even and complete popping. Commercial popping machines use the wet-pop method, and coconut oil is used for its aroma and lightness. Microwave popcorn also uses the wet-pop method, although the moisture is present in a solidified form of oil, flavoring, and salt that melts when the microwaving process begins.

1.2                   DESIGN CONSTRUCTION AND FABRICATION PROBLEM
The problems associated with the design of the machine are discussed below.

1. Selection of stirrer : locally made  popcorn machine has a striver which turns the corn inside the cast opts as heating on. The striver, which rotates due to the rod connected to it from the housing, should rotate with a low speed to produce the desired effect. In our research, we were able to discover that only a low speed stirrer could give the desired turning effect. This stirrer is control manually
2. Heating Element: Another problem in the choice of heating element. There are various kinds of heater available in the market, for the sake of this work, a stove or gas cylinder was used as the heater.
3. Third Design Problem is Control and Safety: In the system we discovered that there is the need for the finance circuit to control the operation of the popcotrrn machine.
4. Construction and Fabrication of the Housing for the Machine: This is fourth problem, which involves the use of per pex holler rectangular aluminum bars in profile glasses and metal handle. With respect to safety. The machine was made to be safer for the users by incorporating the user of insulator in the design. 

1.3                                              OBJECTIVE OF THE DESIGN

1. To eliminate the use of electrical popcorn machine.
2. To save money as most of the work in now done by using electricity.
3. To use human energy in the production of popcorn.
4. To produce popcorn at a reduced cost.

1.4                                                SCOPE AND LIMITATION
This project covers design, construction fabrication and operation of the human operated popcorn producing machine using locally available.

   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 electrical 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 earning for the nation.
