Abstract
A freeze-dried product continuously manufactured by being dried while smoothly moving in a state of receiving a mechanical force in a freeze-drying apparatus. The freeze-drying apparatusincludes a freezing unitfor producing a frozen substance by spraying a raw material solution; and a drying unitfor drying the frozen substance. The drying unithas a tubular shape and includes a tubular memberkept in a vacuum state, and a spiral wall or groove portion is formed on an inner wall of the tubular membercontinuously in a longitudinal direction of the tubular member. A heat is transferred to the inner wall of the tubular memberand the spiral wall or groove portion. The tubular memberis configured to be rotated to transfer the freeze-dried product in the longitudinal direction of the tubular memberand sublimate or dry the freeze-dried product. A flow-start angle is less than 44 degrees or a repose angle is less than 55 degrees and larger than the flow-start angle, and a residual amount is 3 g or less with respect to 10 g of the raw material solution fed into freeze-drying apparatus when a length of the tubular memberis 30 cm in the longitudinal direction.
