PROBLEM TO BE SOLVED: To provide a method for cleaning and drying machining chips, which efficiently removes a cutting oil depositing on the machining chips as much as possible, further is environmentally friendly, and reduces the waste of energy to be consumed.SOLUTION: This cleaning and drying method includes: making the machining chips stay in a furnace 4 for cleaning and drying, which is maintained at a predetermined temperature, for a predetermined period of time; heating a saturated vapor which has been generated in a vapor boiler 7 and has been heated to the first temperature range, to the second temperature range which has higher temperature than the first temperature range in a superheated-vapor-generating unit 8, to produce a superheated vapor; pressure-feeding the vapor into the furnace; and discharging the cutting oil depositing on the machining chips together with the superheated vapor to clean and dry the machining chips. |
