Abstract
A drying process is commonly used in industry. Textile, glass, ceramic, dye
and food could be accepted as leading sectors where the drying process take
parts. During the drying process the aim is to remove water or solvents from
the structure of material which is needed to be dried. For most cases, drying
occurs between production steps and the effectiveness of the drying is quite
important for the coming steps of relevant production processes. Not only are
the properties of material which are needed to be dried, but also the method
of drying is important regarding both effectiveness of drying and energy cost.
Today in industry, besides the importance of first investment cost of systems the
running costs of the systems, have a highly increasing importance. It is wellknown
that the energy cost is a considerable part of running costs. In this study,
concerning the above mentioned reasons, we aim to create a mathematical way
to optimise the drying process concerning “effectiveness of drying” and “energy
cost”. Basically the drying process is a “mass transfer” phenomenon. In this
study, by means of mathematical statements of mass transfer phenomenon, the
drying speed of a liquid with well-known physical properties has been calculated
in a theoretical way and the calculations have been tested by experimental ways.
The results obtained from both mathematical and experimental ways have been
evaluated. A new method is reached by means of a combination of theoretical
calculation and experimental studies to determine the partial pressure of liquids
whose physical properties are not well-known. At the end, experimental studies
have been done to understand the drying properties of glass colours and results
have been evaluated.
