摘要：PROBLEM TO BE SOLVED: To provide an injection device of an adhesion inhibitor in an asphalt plant which eliminates a stirring device for carrying out stirring and mixing in a tank when using the adhesion inhibitor with a separation property. SOLUTION: The injection device is provided with the tank 2 for storing a mixed liquid which is diluted by adding water to the mother liquid of the adhesion inhibitor. A supply pump 5 is arranged at a supply pipe 3 and an injection nozzle 7 is arranged at the end of the pipe through a solenoid valve 6 for injection. A returning pipe 8 for allowing the adhesion inhibitor to flow back to the tank 2 is connected with the supply pipe 3 between the supply pump 5 and the solenoid valve 6 for injection and a pressure relief valve 9 is arranged at the returning pipe 8. If the supply pump 5 is always driven during the operation of the asphalt plant, the adhesion inhibitor supplied from the tank 2 circulates back to the tank 2 through the pressure relief valve 9 and is stirred and mixed in the tank 2 without a stirring device when the solenoid valve 6 for injection is closed, so that the separation of the adhesion inhibitor is inhibited.
