Abstract
A material to be dried is frozen and is efficiently freeze-dried in a short time, thereby increasing production efficiency. A freeze-drying apparatus includes a vertical tube () having an inner circumferential surface formed with a frozen surface (), a liquid-supply device () for supplying a liquid material to be dried () onto the frozen surface (), a freezing device () arranged around the vertical tube () and intended for cooling the frozen surface (), a pressure-reduction device () which puts an interior area of the vertical tube () into a state of vacuum, and an internal heating device () in the vertical tube (). The internal heating device () is arranged in the vertical tube () along a center axis thereof, and has an outer surface formed with a vertically long circular-cylindrical radiation surface (). The liquid material to be dried () supplied from the liquid-supply device () is sprinkled onto the frozen surface (), and the frozen surface () is cooled to freeze the dried material () into a shape of a pipe. Then, the interior area of the vertical tube () is pressure-reduced to supply radiation heat from the internal heating device () to the dried material () for freeze-drying the dried material ().
