The invention discloses an intelligent hot-air drying control device which comprises a heat exchange box and a drying chamber, wherein he heat exchange box is separated into multiple spaces, and the drying chamber is connected with the heat exchange box through an air supplying main pipe and a general air return pipe. A heat pump dehumidifying and heating system, a heat pipe return heat exchange system, a hot air circulating system and an intelligent control system are arranged in the heat exchange box. The heat pump dehumidifying and heating system which is composed of a compressor, a drying filter, a dehumidifying evaporator, a throttle valve and a heating condenser. The heat pipe return heat exchange system is composed of a heat pipe evaporator and a heat pipe condenser. The hot air circulating system is composed of a high-pressure refrigerant liquid connecting pipe, a low-pressure refrigerant return gas connecting pipe, a high-pressure refrigerant gas connecting pipe, a liquid refrigerant connecting pipe, a gas refrigerant connecting pipe, an air exhaust regulating valve, a mixed air box, a fresh air regulating valve, a secondary air flow regulating valve and an air blower assembly. The intelligent control system is composed of the a temperature sensor, a humidity sensor, a hot air temperature sensor and a hot air humidity sensor, wherein the temperature sensor, the humidity sensor, the hot air temperature sensor and the hot air humidity sensor are connected in the various systems. The intelligent hot-air drying control device can regulate the temperature and the humidity of drying air automatically and improve the material drying efficiency.
