摘要:
[Object] To provide a freeze-drying apparatus and a freeze-drying method, which are capable of increasing a collection rate of a raw material without a need for providing a member such as a baffle plate or the like. [Solving Means] The freeze-drying apparatus 100 includes: a container 4 to store a raw material fluid F a freezing chamber 10 being a vacuum chamber a vacuum pump 1 to exhaust the freezing chamber 10 and an injection mechanism 25 to inject the raw material fluid F stored in the container 4 into the freezing chamber 10. The cold trap 20 is arranged within the freezing chamber 10, and hence a phenomenon that the raw material is discharged to the outside of the vacuum chamber together with a vapor as in the past can be prevented. With this, the collection rate of the raw material can be increased. Further, it becomes unnecessary to provide the baffle plate or the like for preventing the phenomenon in vicinity of an exhaust port of the vacuum chamber.
