DESIGN AND CONSTRUCTION OF A SPIN DRYER

ABSTRACT

This work is aimed at designing and fabricating a spin dryer which can be used in drying spent grains after brewing. This will no doubt save considerable human labours and time wastage involved in conventional method of drying the spent grains by spreading on the ground. It also saves as a means of employments for our teaming population. This machine was designed after due consideration of its ease of production, maintenance and servicing. Chapter one gives account of the introductory background of the project. Chapter two was the literature review of the project. Chapter three was the synthesis of solution under which different alternatives, comparison of alternatives and choice were discussed. In chapter four, effort was made to discuss the Analysis and Theory of design. The details of construction, Maintenance, Procedures and testing and evaluation were discussed, In chapter five. After the testing, it was found to perform effectively and efficiently. Chapter six became the home for Material evaluation, machine and labour cost analysis. Finally was chapter seven, where we based our discussion on the project, possible recommendations and conclusion.

CHAPTER ONE

INTRODUCTION

IDENTIFICATION OF NEEDS

Machine design is the creation of new and better machines and improving the existing ones. A new or better machine is one which is more economical in the overall cost of production, operation and maintenance.

It is on these background that we came out with a design of a machine, which shall help in solving problems of drying spent grains in our breweries.

The major problem facing breweries in the country in how to utilize the spent grains after brewing. Though some breweries use these spent grains as aids by drying and burning them. We hence see this method of recognition as not being economical but wasteful.

There  propelled us to designing a new method of  drying these spent grains to the required moisture content through the use of a SPIN DRYER. When these spent grains are properly dried, it could be a major constituent in the production of  poultry feeds.

With this spin dryer, the unemployed masses could gain jobs by fabricating or buying  this machine for drying of spent grains, and recycling it to a useful feed for poultry.

It  is worthy  to note that the production of a spin dryer is designed in a way that even the unskilled workers could operate it, in fact, we are designing this project as our quota towards the  eradication of unemployment and poverty, which this present government is wedging war against.

Moreover, technology could be bought, borrowed or stolen. Our project is a borrowed technology from the western world, which was primarily used for drying of clothes, but we have expanded this scope to deal favourably with drying of spent grains to the desired moisture content.
