Selected copra is loaded into a hopper of capacity 10 tons. Hopper has a mesh at bottom to allow air to come inside but prevent copra from falling down. Hot air of about 75-80 degrees is generated using steam radiator and pumped into hopper using a centrifugal blower. Hot air is supplied continuously for about 10 hours. Moisture level reduces from initial 5% to 2.5%. After drying copra becomes hard and brittle. Moisture when present in oil causes rancidity, so when moisture is removed shelf life of oil increases. Oil extracted from moisture free copra can be finely filtered too.
