MULTI-PURPOSE DRYING APPARATUS WITH IMPROVED DRYING EFFICIENCY USING A HEAT PUMP SYSTEM AND A HEAT TRANSFER SYSTEM

摘要

PURPOSE: A multi-purpose drying apparatus with improved drying efficiency is provided to enable smooth circulation of dry air by preventing the inflow and outflow of wet air.;CONSTITUTION: A multi-purpose drying apparatus(1) with improved drying efficiency comprises a drying body(10), a heat pump system, and a heat transfer system(50). The drying body comprises a material input port(11), a material output port(12), a drying room(13), and an air circulation passage(14). The drying room is formed between the material input port and the material output port. The air circulation passage connects to one side and the other side of the drying room. The heat pump system comprises an evaporator(31), a condenser(32), a compressor(33), and an expansion valve. The evaporator and the condenser are installed in the air circulation passage of the drying body. The compressor compresses working fluid flowing out from the evaporator. The expansion valve expands the working fluid flowing out from the condenser. The heat transfer system heats and cools the air flowing in through the air circulation passage.;COPYRIGHT KIPO 2011
