状である。In conventional devices of this type, the rotating blades rotate independently without interfering with each other, so if there is a cross-talk object attached to the blade or the surface of the rotating shaft (2), and the device is stopped for a long time, cross-talk may occur. As the material dries and solidifies, the surface of the blades and rotating shaft (the surface of the blades and rotating shaft becomes two pieces of log), which significantly reduces work efficiency, so it is necessary to clean it by scraping it off and washing with water after stopping.
The current situation is that its maintenance and maintenance requires a lot of time and effort.
