Optimization in rubber wood using a Combined Microwave, Hot Air and Continuous Conveying Drying Process by Energy and Exergy Analysis.

Abstract

This research was conducted to study the Optimization in rubber wood using a combined microwave, hot air and continuous conveying drying process by energy and exergy analysis. Three part of para wood, topper part, middle part and base part of the trunk. The chemicals included two types of chemical and diesel in the ratio of 50: 50 and baking moisture in hot air at temperature of 60 ° C and the baking moisture with microwave energy, the wattage 100 W oven to keep the moisture in wood to 15. % and are tested for resistance to compression. The study found that the base of the para through a chemical bath through a moisture with microwave energy spent nine hours, 40 minutes, receiving a compressive strength in the direction perpendicular to the grain maximum of 17.99 MPa, there was resistance increased 62% and para wood through a chemical to dissolve in . Solar Through baking, hot air moisture takes 24 hours to get a compressive strength in the direction parallel to the grain of 40.31 MPa maximum strength resistance increased 137% from the moisture baked with microwave energy. If the moisture content of the a-ttom of the oven with hot air. Which will take the total it takes time to bake moisture for up to 12-48 hours.
