This application provides a wool product drying apparatus, method, drying equipment, and storage medium, relating to the field of household appliance technology. Initially, the drying module heats the air on one side of the air inlet of the drying cylinder at a first heating efficiency (e.g., operating at a high power or frequency), causing the air to carry a significant amount of heat. When this heated air is blown into the drying cylinder to dry the wool products, the wool products are relatively moist, with a large amount of moisture evaporating. The moisture has a strong ability to absorb heat from the air, thus most of the heat carried in the air is dissipated. This results in a rapid drying rate for the wool products, maintaining a relatively low temperature for both the wool products and the air, with a slow temperature rise. This allows for rapid dehydration of the wool products and prevents shrinkage, deformation, and pilling, ensuring the quality of the wool products.
