Drying
ABSTRACT
In this experiment,we use a microwave dryer to dry the wet sand . We choose to use a mixture of sand and water because we believe that sand is a solid which possesess both regular and irregular crystal lattice structure , therefore making the movement of water particle easy and decrease faster ,leading to a short drying time.
The measurement of the moisture content is based on the weight sample which is inversely proportional with the temperature and time , though the temperatue is kept constant throughout the experiment .Thus we can determine the drying rate of the sample based on the data obtained from the experiment ,the mass and moisture content is decreasing with time whereas the drying rate is varying rapidly with time.

CHAPTER ONE
INTRODUCTION
Drying is a thermal process which involves the final removal of volatile constituent from a substance to reduce the content of the residual liquid to an acceptable low value .Drying of a material is often the final step in a series of operation in manufacturing process, carried out immediately prio to packaging or dispatch. Excluding the partial drying of a solid by mechanical means (e.g centrifuges) for example ,by squeezing all drying operation depends upon the application of heat to vaporize the volatile constituent either completely
