The invention provides a drying apparatus and a method for a raw silk degumming process. The drying apparatus includes a drying oven in which a silk strand cover and an air supply unit are disposed. An upper opening and a lower opening are respectively provided at the top and the bottom of the silk strand cover. A silk strand to be dried passes through the silk strand cover. A convex portion is disposed on a sidewall of the silk strand cover, which is protruded toward an outer side of the silk strand cover. The air supply unit is used for providing an air supply flow into the silk strand cover to dry the silk strand. A falling point of the air supply flow is located at the convex portion of the silk strand cover. By means of the apparatus, silkworm silk can be endowed with special elasticity and fluffiness performances.
