CHAPTER ONE

1.0 INTRODUCTION

The project titled fabrication of machine is used for grinding domestic food stuff like corn, pepper, beans, tomatoes, melon

e.t.c. The grinding operation was carried out in the olden days with the aid of grinding stone. This method is very tedious and unhygienic in nature. The particle of the grinding stone can easily be mixed with the grinding food items which may be hazardous to the food itself and also to the personnel undertaken such task by entering his or her body. It takes a lot of time and energy during operation (wwwcrushermachine.com).

Pepper grinding machine was fabricated purposely to overcome all the challenges which may be encountered when grinding using this primitive method. It can also be used for commercial purpose. Some of the machines were made to be operated manually. With this type of machine, series of labour is been done and a lot of energy been wasted in undergoing such task.
