The box-type sludge low-temperature dryer uses a lifting forklift to fork the automatic unloading bucket filled with wet sludge into the equipment. After closing the equipment seal door, set parameters, start the equipment, and automatically stop the equipment after reaching the set running time or set humidity. Open the equipment seal door, the forklift will assist in forking the automatic unloading bucket, place it on the unloading platform, unload the sludge with one click, and then unload the sludge.
