Development of Teak Wood Dryer and Optimization of Drying Condition by Mathematical Modeling

Abstract

The objective of research of development of teak wood dryer and optimization of drying condition by mathematical modeling has create and development teak wood dryer. It was for reducing various problems regarding the quality of teak wood does not affect the environment by designing and creating a combined teak wood oven. There are 3 parts to the working system: 1) Structure of the teak oven was designed to receive light throughout the day with a tunnel shape. There is an exhaust fan working to reduce the temperature in the oven. 2) Providing heat energy from hot air. It will provide heat energy to the oven. When the oven does not receive heat from the sun or the temperature is not as specified and 3) the controlling the teak wood oven system Inside the teak wood oven the temperature and humidity are controlled. It is used in editing the heating systems of both systems. The mathematical modeling using non–linear regression analysis of a combined oven for drying teak wood by using the value of the decision coefficient (R²), the chi–squared (X²), and the lowest square root of the mean square error (RMSE). It was found that the Diffusion approximation model is suitable to predict the moisture ratio of teak during drying for drying using a combined drying oven. The decision coefficient is equal to 0.9853, the chi–squared reduction value, And the square root of the mean square error is 0.0001 and 0.0112, having the lowest values.
