HEAT PUMP DRYER USING WASTE HEAT OF MICROWAVE DRYER AND DRYING METHOD USING SAME

摘要

An embodiment of the present invention provides a dryer capable of saving energy and accurately controlling the drying temperature by using a heat pump capable of using waste heat of a microwave dryer as a heat source, a device forming a variable air flow path or the like and a drying method using the same. According to an embodiment of the present invention, a heat pump dryer using waste heat of a microwave dryer comprises a microwave generation device, a first dry chamber, a second dry chamber, a mixing device, a hot air generation part and a microwave generation device cooling water pipe. The microwave generation device generates a microwave. The first drying chamber dries the to-be-dried subject though heating by microwaves transferred from the microwave generation device. The second drying chamber secondarily dries the to-be-dried subject transferred after being dried in the first drying chamber. The mixing device allows air discharged from the first drying chamber and the second drying chamber to be introduced thereinto to mix waste heat of the first drying chamber with waste heat of the second drying chamber. The hot air generation part allows air discharged from the mixing device, performs a function to generate hot air to be supplied to the second drying chamber, and includes a heat pump part and a hot air duct capable of forming a plurality of variable flow paths. The microwave generation device cooling water pipe is included in the microwave generation device.;COPYRIGHT KIPO 2017
