PURPOSE: A portable apparatus for drying an inorganic-based coating film of superior hardness is provided to coat the surface of a base material at low temperatures and to expand the life of the base material. CONSTITUTION: A portable apparatus(10) for drying an inorganic-based coating film of superior hardness includes a housing(110), a heating unit(120), and a controlling part(140). A handle(112) is arranged at the housing. The heating unit is arranged in the housing and heats air introduced by a blower at a temperature between 150 and 500 degrees Celsius. The heating unit is one selected from a microwave-based heater, a ceramic coil-based heater, and a gas furnace. The controlling part electrically controls the heating unit and operates the heating unit based on external power. The controlling part is a silicon controlled rectifier. |
