Drying system

A drying system, comprising:

• a drying chamber configured to accommodate a material to be dried;
• a collecting apparatus connected to a material outlet of the drying chamber;
• and
• an air feed apparatus connected to an air inlet of the drying chamber and configured to feed air to the drying chamber,
• wherein the air feed apparatus comprises a first condensing mechanism, a first heating mechanism, and a first water content sensor, wherein along an air feed direction of the air feed apparatus, the first condensing mechanism is located upstream of the first heating mechanism;
• the first condensing mechanism is configured to reduce water content of gas entering the drying chamber;
• the first heating mechanism is configured to heat the gas entering the drying chamber;
• and the first water content sensor is disposed between the first condensing mechanism and the first heating mechanism and is configured to detect water content of gas discharged from the first condensing mechanism and generate a water content signal.
