After mixing and molding the binder in the fiber, the moisture contained in the binder is dried to prepare a cover.

As a method of drying the moisture, in addition to the hot air circulation method, a drying method by high frequency heating disclosed in Republic of Korea Patent Publication No. 10-0407828 (Nov. 19, 2003) is mainly used, and Republic of Korea Patent Publication No. 10-0407828 (2003.11.19) The high frequency drying device of the method disclosed in Fig. 1) requires high drying temperature in order to dry the moisture within a short time since the drying of the moisture is carried out in a single step when the sludge or the waste is continuously supplied and discharged from the outside by the conveyor belt. Therefore, the amount of energy consumed by the high frequency generator is increased to increase the temperature inside the drying device, and the time required for heating the water contained in the sludge or garbage up to the set temperature is increased, thereby reducing the efficiency of drying. There is this.
