The staff adjusts the temperature of the heating tube 20 to an appropriate temperature. The staff then pours an appropriate amount of asphalt into the processing barrel 2 through the feeding funnel 8 for stirring. At this time, the staff adds an appropriate modifier to the feeding funnel 4 (different feeding funnels 4 can add different modifiers), and then starts the third electronic valve 18. The modifier falls into the storage tank 17 along the feeding pipe 3. The hanging scale 25 (the hanging scale 25 is in a zero state before the modifier is added) accurately weighs the modifier in the storage tank 17 and visually displays the weight through the display screen 5. When the modifier reaches the appropriate weight, the third electronic valve 18 is closed, and the second electronic valve 15 is opened to allow the modifier to fall into the asphalt being stirred such as asphalt fusion, and finally discharged from the discharge pipe 10.

After the staff pours the modifier into the feed funnel 4, the third electronic valve 18 opens automatically, and the display screen 5 can visualize the weight on the hanging scale 25 to facilitate staff observation. The weight detection module in the hanging scale 25 will feed back information to the control main board of the control panel 11 when the modifier reaches the preset weight, and the third electronic valve 18 will be closed, and then the second electronic valve 15 will be opened to allow the modifier to fall into the processing cylinder 2.
