PURPOSE: An air drier comprising plate heat exchanger in which separator is installed is provided to prevent loss of heat transfer, maximize discharge efficiency of condensate water and minimize and lighten a frozen air drier product by installing separator connected to an outer part of the heat exchanger by pipeline in the heat exchanger. CONSTITUTION: In constructing an air drier using an ordinary plate heat exchanger comprising a reheater(4) in which a plurality of creased heating plates(1) are stacked, and on which inflow hole(2) and outflow hole(3) having different compressed air channels in the reheater are formed; and a chiller(7) in which a plurality of the creased heating plates(1) are stacked, on which refrigerant inlet(5) and refrigerant outlet(6) connected by refrigerant channel are formed, and in which compressed air channel is formed, the air drier comprising plate heat exchanger in which separator is installed is characterized in that an adiabatic expansion chamber(8) is formed on a lower part of the chiller that is a pipeline through which compressed air cooled in the chiller is transferred to the reheater, and a cohesion mesh(9) is installed in a lower part of the reheater connected to the adiabatic expansion chamber, wherein a wall body pipe(10) is installed between the reheater and the chiller to divide them, and a hole(11) oppositely directed to the reheater in which the compressed air of the reheater is flown, a hole(12) oppositely directed to the chiller from which the compressed air is transferred to the chiller, and a through hole(13) for connecting the chiller to the reheater are formed on the wall body pipe.
