CONSTRUCTION OF MOTORIZED MIXER

CHAPTER ONE

INTRODUCTION

1.1 Background of the Study

The construction of motorized mixers has gained significant attention in various industries due to the increasing demand for efficient and consistent mixing processes. Motorized mixers are essential in sectors such as construction, food processing, pharmaceuticals, and manufacturing, where they help achieve uniformity in the mixture of materials. Traditional manual mixing methods are often labor-intensive and can lead to inconsistencies in the final product. The advancement in technology has led to the development of motorized mixers that enhance productivity, reduce human effort, and ensure the homogeneity of mixtures. This study explores the construction of a motorized mixer, highlighting its design, functionality, and benefits.

1.2 Statement of the Problem

Despite the numerous benefits of motorized mixers, many small-scale industries and individual users still rely on manual mixing methods due to the high cost and limited availability of commercial motorized mixers. Manual mixing not only consumes more time but also poses physical strain on workers and often results in inconsistent mixtures. This study aims to address the gap by developing a cost-effective motorized mixer that can be easily constructed and maintained, thus providing a practical solution for small-scale applications.
