What do you mean by drying?

Sun drying is a traditional food processing method, which means drying raw materials in the sun or other warm environment. In ancient times, especially in the era when there were no modern preservation technologies such as freezing and pickling, drying in the sun was the main way for people to preserve ingredients. Sun drying can not only increase the shelf life of food, but also make the ingredients more sweet and delicious. Although there are more ways to preserve food now, in some places, such as rural areas, people still use natural resources for drying.

Sunlight can be used not only for processing raw materials, but also for dyeing textiles. In ancient times, people used the sun's irradiation to dry dyes and fabrics together to realize dyeing. Compared with modern dyeing methods, sun dyeing process is complicated, but it can maintain the natural texture of dyes and has unique color.

Although sunbathing is used less frequently in modern life, sunbathing is still a very basic way of life in some rural areas. For example, in some places, people will use natural wind to dry crops for storage and use. At the same time, in some areas that still maintain traditional agricultural methods, in order to save energy, people will choose drying in the sun as a simple and natural way to preserve food.
