Several material delivery branch pipes 8 are respectively connected and fixed, and several material delivery branch pipes 8 are respectively provided with feed valves 9, several storage bins 1 are respectively opened with air inlets 10 on the right sides of the outer walls, several cover plates 3 are respectively opened with flow ports 11 on the top surfaces, and fans 12 are respectively fixed inside the flow ports 11, and the fans 12 are electrically connected to the PLC controller; several steam generators 13 are fixed on the rear side of the outer wall of the mounting frame 2, and the steam generators 13 are electrically connected to the PLC controller; and delivery pipes 14 are respectively connected and fixed between the several steam generators 13 and the several storage bins 1.

[0023] In use, the staff uses the exhaust fan 5 and the feed pipe 7 to suck the foam particles produced by the foaming equipment 4 into the storage bin 1 for storage. During the storage of the foam particles, the steam generator 13 is started to facilitate the delivery of steam to the interior of the storage bin 1, providing the necessary heat to promote the volatilization of the foaming agent and the expansion of the particles, and also to maintain the temperature of the entire processing environment stable.

In addition, the staff starts the fan 12 to allow external air to enter the storage bin 1 through the air inlet 10 and then be discharged from the circulation port 11 to promote air circulation, thereby controlling the humidity level in the environment. The fan 12 and the steam generator 13 facilitate the temperature and humidity treatment of the interior of the storage bin 1, which helps to prevent moisture accumulation and reduce the growth of mold and bacteria, provide a stable and suitable environment, and improve the storage conditions of the foam particles, thereby improving the quality of the foam particles, ensuring the smooth progress of the production process and the consistency of product quality.
