PROBLEM TO BE SOLVED: To provide a heat exchanger capable of improving production efficiency.SOLUTION: A heat exchange fluid supply pipe 3 connected to a heating vapor source is connected to a jacket part 2 of a reactor 1. A discharge pipe 19 is connected to a lower left part of the jacket part 2 of the reactor 1 to communicate a gas/liquid separator 20 with a steam compressor 6, and further a discharge pipe 21 is connected to the heat exchange fluid supply pipe 3. An upper discharge pipe 7 is attached to an upper left part of the reactor 1 to connect a gas/liquid separator 9 to a steam compressor 8, and further a discharge pipe 10 on the outlet side of the steam compressor 8 is connected to the heat exchange fluid supply pipe 3. By heating the reactor 1 and then sucking the inside of the reactor 1 through the upper discharge pipe 7, a heat-exchanged object in the reactor 1 can be concentrated and dried. |
