[0002] Autoclaved aerated concrete (AAC) products require curing in an autoclave during production. This curing process involves continuously filling the autoclave with large amounts of high-temperature, high-pressure steam. After curing, the vent on the autoclave lid is opened to release the steam, and then the lid is opened again, allowing a crane to lift the AAC product out of the autoclave. Each curing cycle requires the removal of a large amount of steam, wasting heat and water. Furthermore, the large amount of steam entering the production workshop can lead to excessive humidity, affecting the normal operation of other equipment and compromising worker safety.
