The air containing this solvent evaporation and moisture is sent to the cooling chamber, where it is cooled and the solvent vapor is liquefied and separated along with the moisture.The cooled air is heated again in the heating chamber and sent to the drying chamber. Air is sequentially circulated through the heating chamber, drying chamber, and cooling chamber to recover the solvent, and when the concentration of solvent vapor increases, or when outside air is introduced during the solvent recovery and circulation process, or at the end of the drying process, etc. When the air in the drying room is released into the atmosphere, the exhaust air is cooled and released, so by cooling, the solvent vapor in the air is separated and recovered, increasing the solvent recovery efficiency, and some amount is released into the atmosphere. Even if it contains a lot of solvent, it has little odor because it is cooled.
