Drying process in most cases are accomplished by the open sun. Meanwhile, the environmental condition in solar tunnel drying is enclosure type and the product is protected from rains, dust, insects, and rodents. Solar tunnel drying, a widely used bulk dryer, facilitates faster drying than open drying by virtue of the greenhouse effect.

Ginger rhizomes were harvested and divided into three groups according to their age of 4-6, 7-9, and 10-12 months. The results revealed that as ginger rhizomes age, moisture content and density decreased, while fibre and 6-gingerol content increased. Therefore, ginger maturity with the age of 10-12 months was used in the drying process.
