    • A method for controlling a drying machine which includes a drum, a fan to circulate air within the drum, and at least one heater to heat air provided to the drum, and uses the motor and the at least one heater as a load, includes, upon receiving a drying process command from a user, receiving power rate information for each hour from an energy management system (EMS), recognizing current power rates on the basis of the power rate information for each hour, determining whether the current power rates are higher than reference power rates by comparing the current power rates with the reference power rates, and adjusting the operation rate of any one of the motor and the at least one heater when the current power rates are higher than the reference power rates. The drying machine changes the load operation rate before the power rates exceed the reference power rates, resulting in reduction in power consumption. Furthermore, as the drying machine can prevent total power consumption from being rapidly increased, the power plant need not be additionally driven to generate more electricity. As a result, the drying machine reduces environmental impact and prevents power rates from being increased.
    • 一种干燥机的控制方法,其特征在于,包括:滚筒,使所述滚筒内的空气循环的风扇;以及至少一个加热器,用于加热设置在所述滚筒上的空气,并使用所述马达和所述至少一个加热器作为载荷; 从用户接收到干燥处理命令,从能量管理系统(EMS)接收每小时的功率率信息,根据每小时的功率率信息识别当前功率,确定当前功率是否更高 通过将当前功率率与参考功率比进行比较,并且当当前功率率高于参考功率时,调整电动机和至少一个加热器中的任何一个的运行速率。 干燥机在功率速率超过参考功率之前改变负载运行速率,从而降低功耗。 此外,由于干燥机能够防止总功率消耗快速增加,所以不需要额外地驱动发电厂以产生更多的电力。 因此,干燥机可以减少环境影响并防止功率增加。
