To improve sun drying: Spread the grains in thin layers of ideally 2–4 cm. Very thin layers tend to heat up very quickly with a negative effect on head rice recovery. If layers are too thick, a large moisture gradient develops with dry grains on the top and wet grains on the bottom, which reabsorbs moisture after mixing, resulting in cracked ...
