Since the quartz crucible is fragile, in order to avoid the safety hazard of impurities to the quartz crucible under high temperature, the quartz crucible before use needs to be dried.

At this time, the temperature of the air flow transferred from the heat steaming box 160 to the exhaust fan box 120 will gradually decrease, so that the problem of cracks caused by sudden temperature drop after high-temperature drying of the quartz crucible 500 can be avoided.

[0071] Although the embodiments of the present application have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and purposes of the present application, and the scope of the present application is defined by the claims and their equivalents.
