Document Type and Number:
WIPO Patent Application WO/2017/121260
Kind Code:
A1
Abstract:
A drying system combining hot air drying and cold air drying comprises a solar greenhouse (1), an air condenser (2), a water-bath deduster (9), a heat source, an air heater (4), a smoke refrigerating device, an air cooler (8), pipes connected to the devices, and valves (13.1-13.5) and a fan (7.1-7.6) disposed on the pipes. The solar greenhouse (1) is a sealed structure, and the air condenser (2) is a cylindrical structure. The heat source is connected to the air heater (4). An air inlet of the solar greenhouse (1), an air outlet of the air condenser (2) and an outlet of the air heater (4) communicate with one another by means of the pipes. An air outlet of the solar greenhouse (1) communicates with an air box (2.1) above the air condenser (2) by means of the pipe. A smoke outlet of the air heater (4) is connected to the smoke refrigerating device. Energy is utilized at multiple levels on the system, thereby improving the thermal efficiency of drying.
