PENGERINGAN REMPAH-REMPAH MENGGUNAKAN ALAT ROTARY DRYER (Determining the Rate of Drying Spices on the Rotary Dryer)

Abstract

Drying is a water process discharge of the material by using heatenergy so that the water content of the material is decreased. Drying process is usually accompanied by the evaporation of watercontaine in the materials. In this lab used a rotary dryer dryers to dry the spices. Rotary dryer consists of a horizontal cylindrical shell mounted on a roller bearing, so the cylinder can rotate and form a tilt angle position slightly. Feedin serted at the high end of the cylinder, and will come out as a dry product at the other end. As the heater can be used hot air or exhaustcombustion products still have a high temperature. In the drying of spices using rotary dryer can be concluded that the higher the temperature the higher the rate of drying is used and the more material used the lower the rate of drying. The rate of drying will decrease if the water layer that covers the material has a thin, waterin uapkan the less, so it needs a little heat.
