[0003] During the traditional polyurethane controlled-release fertilizer coating process, the motor on the coating machine is first started to make the coating cylinder rotate, and then the controlled-release fertilizer particles, oily anti-caking agents, powdered anti-caking agents and other materials are added into the coating cylinder, so that the materials are swirled and mixed in the coating cylinder to complete the coating process. However, it is found in actual use that when the controlled-release fertilizer and other materials are swirled and mixed in the coating cylinder, some of the materials will adhere to the inner wall of the coating cylinder, thereby affecting the normal use of the controlled-release fertilizer or reaction materials. At this time, the staff needs to switch the equipment on and off from time to time to clean it, which reduces the working efficiency of the coating machine and affects the coating effect of the controlled-release fertilizer.
