Abstract
A drying apparatus, particularly suitable for disposing water-containing organic waste. The drying apparatus includes a drying chamber with a circular cross-section, where waste enters the drying chamber through a waste inlet and undergoes rotational movement within the drying chamber due to a negative pressure generated by an air pump. The air pump draws out airflow from the drying chamber through an air duct connected to the flow outlet, ensuring that the waste continues to rotate during the drying process. Additionally, the apparatus is equipped with a microwave generating device, which directs microwaves into the drying chamber either directly or via a microwave conduit to efficiently dry the waste. This design combines the cyclonic motion with microwave heating, significantly enhancing drying efficiency and ensuring that the waste is fully dried in a short time, making it particularly suitable for disposing organic residue that requires rapid drying.
