Provided is a supercritical drying method of a silica wet gel blanket and a method for producing a silica aerogel blanket including the same, the supercritical drying method preventing a salt from being accumulated inside equipment during supercritical drying. By preventing a salt from being accumulated inside equipment during supercritical drying, it is possible to improve the operational stability of the supercritical drying process. In addition, since only a line filter needs to be separated and is easily washed, the time required for washing and the total amount of ammonia wastewater generated therefrom can be reduced, thereby improving efficiency and reducing costs.
