Abstract

Drying is one of the most important operations in the PADDY processing. In general, the method of drying and its precision level has a profound impact on product quality and amount of losses. For this reason, various methods were suggested to dry PADDY. Developing and using important factor in processing of rice. The control of the grain final moisture content is not necessarily implemented, excessive moisture extraction may cause in an increase of losses and reduction of quality. Lack of control in the drying process causes fissuring of rice in the dryer which results in rice breakage and loss of quality during the subsequent hulling and polishing operations. Hence, controlling the graing moisture content is a key factor in the drying process. Determination of the relationships between grain moisture content with temperature and relative humidity of the exhaust air from the dryer through the drying process is critical. The investigation was conducted in order to determine the relationships between the effective parameters in the INTERMITTENT DRYING process. In this study, grain moisture content as well as temperature and relative humidity of the exhaust air were measured. Analysing of the data enabled to develop a mathematical relationship between the parameters. Based on the results, temperature and relative humidity (RH) of the exhaust air had linear relationship with time, while the relationship between grain moisture content (M.C.) and time was a second order polynomial. Similarly, grain M. C. with exhaust air temperature and grain M. C. with RH relationships were second order polynomials. Using these equations and utilizing Lagranges polynomial interpolation method, a two-tier mathematical model was estimated to relate grain M.C. with temperature and relative humidity of the exhaust air. Based on the relationship, between the effective parameters, grain moisture content could be estimated at any time during drying by simply measuring temperature or relative humidity of the dryer exhaust air.
