DRYING EQUIPMENT HAVING HEAT PUMP COMBINED THERMAL STORAGE TANK AND COOL STORAGE TANK AND DRYING METHOD USING THE SAME

摘要

The present invention relates to a drying apparatus having a drying copper (100) for receiving and drying an object to be dried, wherein the drying copper is provided with a blowing fan (60) and a cooling A cooling water heat exchanger (40) and a temperature elevating heat exchanging unit (50) are provided, and a cooling water heat exchanger (120) for supplying cold water to the cooling heat exchanging unit (40) And a heat pump 150 for generating cold water and hot water to supply the hot water to the axial cold water tank and the heat storage water tank, respectively. According to the present invention, the temperature of the air to be supplied to the drying chamber and the temperature of the inside of the drying chamber are controlled using the water in the heat storage tank (13) and the axial water storage tank (12) In particular, during the winter season, the drying step of the drying chamber is completed, the drying object is taken out from the drying chamber to the outside, and a new drying object in a low temperature state is placed in the initial state of drying and the high temperature air is immediately supplied to improve the drying function. It is possible to supply stable low-temperature air for a long period of time, so that it is possible to provide a high-quality dried product and an improved dry productivity.
