摘要： A technology for protecting a valve seat inside a collection tank from the adherence of frozen particles in a vacuum freeze-drying apparatus and a frozen particle manufacturing method. The inside of a vacuum tank 11 and a collection tank 12 are vacuum evacuated, a raw material liquid is injected into the vacuum tank 11 to produce frozen particles, and the frozen particles are piled up on a surface of a heating/cooling shelf 17. After a first opening 22 of a main pipe 21 which is exposed inside the collection tank 12 is opened, an auxiliary pipe 31 inserted into the main pipe 21 is moved to a position where the bottom end of the auxiliary pipe 31 protrudes to the outside of the main pipe 21 through the first opening 22. When the frozen particles on the heating/cooling shelf 17 are transferred into the collection tank 12 through the inside of the auxiliary pipe 31, the frozen particles do not adhere to a valve seat 23 which surrounds the first opening 22. Next, the auxiliary pipe 31 is moved to a position where the bottom end enters the inside of the main pipe 21 through the first opening 22; the first opening 22 is blocked, and the frozen particles are carried out from the inside of the collection tank 12.

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.摘要翻译： 本发明提供一种不需要设置挡板等构件就能够提高原料的回收率的冷冻干燥装置和冷冻干燥方法。 [解决手段]冷冻干燥装置100包括：容纳原料流体F的容器4; 作为真空室的冷冻室10; 用于排出冷冻室10的真空泵1; 以及注入机构25，用于将容纳在容器4中的原料流体F注入冷冻室10中。冷阱20布置在冷冻室10内，因此原料被排出到冷冻室10的外部 可以防止真空室与过去一样的蒸气。 由此，可以提高原料的回收率。 此外，不需要设置用于防止真空室的排气口附近的现象的挡板等。

摘要： [Object] To provide a freeze-drying apparatus capable of achieving an increase of a processing capacity without causing a variation of a particle diameter.
[Solving Means] A freeze-drying apparatus 100 according to an embodiment of the present invention includes: a freezing chamber 10 forming a vacuum chamber; and an injector 25. The injector 25 includes a tube member 29 provided to the vacuum chamber, and a nozzle 9 including a plurality of injection holes 92 open to an inside of the tube member 29. The injector 25 injects a raw material fluid F, which is fed to the tube member 29, from the nozzle 9 into the vacuum chamber. The respective injection holes 92 are each formed so as to be open to the inside of the tube member 29, and hence the raw material fluid F is injected through the respective injection holes 92 at the same injection pressure. With this, it is possible to achieve the increase of the processing capacity without causing the variation of the particle diameter.摘要翻译： 本发明的目的在于提供一种冷冻干燥装置，其能够在不引起粒径变化的情况下实现处理能力的提高。 [解决手段]根据本发明实施例的冷冻干燥装置100包括：形成真空室的冷冻室10; 喷射器25.喷射器25包括设置在真空室中的管构件29和包括向管构件29的内部开口的多个喷射孔92的喷嘴9.喷射器25喷射原料流体F， 供给管件29的气体从喷嘴9进入真空室。 各注入孔92形成为向管部件29的内部开口，因此原料流体F以相同的注入压力从各注入孔92注入。 由此，可以实现处理能力的提高而不会导致粒径的变化。
