1. Easy-to-operate thermostat, enabling operator to preset room temperature to meet process requirement（T≤65℃);
2. Multiple circulation fans, generating hot air at intervals to prevent the surface of plaster molds drying too fast and maintain an even temperature and humidity in all parts of the room;
3. Advanced control system, automatically controlling the ignition, heating and draining processes, requiring no manual operation. Shutting down burners and giving alarms automatically in case of a control system failure;
4. Walls made of quality thermal insulation boards( with a heat conduction rate（λ=0.0175 kilocalorie/meter·hour·degree), achieving a very low heat dissipation.

To save investment and manufacturing cost, the system can be further customized to exploit the remaining heat during the cooling of the kiln as heating source.
