[0023] The working principle of the heat exchange component of the energy-saving flash dryer provided by this utility model is as follows: In use, the flash dryer heated by steam is connected to storage box 2. After the steam passes through the steam heat exchanger, it is heated to obtain high-temperature hot water at about 90°C for storage.

[0024] After the water pump 31 is started, the hot water inside the storage tank 2 is transported into the heating tank 41 through the delivery pipe 32, and then discharged through the drain pipe 33.

[0025] Meanwhile, fresh air enters the interior of the heating tube 43 through the input pipe 42 and is then discharged into the flash dryer through the output pipe 44.
