  • Patent number: 11732965
    Abstract: A freeze-drying device includes a controller configured to control depressurization of containers filled with a liquid including a raw material and a medium to freeze the liquid from a liquid surface. The freeze-drying device also includes a gas capture pump configured to exhaust a freeze-drying chamber accommodating the containers, and a positive-displacement pump configured to discharge gas from a space accommodating the gas capture pump. The controller executes an exhaust mitigation process that performs the depressurization at an exhaust capability that is less than a rated exhaust capability of the freeze-drying device. The controller uses a partial pressure value of the medium to determine when the exhaust mitigation process ends. The controller maintains an exhaust speed of the gas capture pump and decreases an exhaust speed of the positive-displacement pump in the exhaust mitigation process.

  • Patent number: 11723870
    Abstract: Herein described are an assembly, apparatus and method for lyophilization that utilizes a thermal block made from a conductive material, the block having multiple wells designed and dimensioned to receive containers carrying material to be lyophilized in situ. In preferred embodiments, a vented silicone pad covers the wells and secures the containers therein, and a similarly vented rigid plate in turn secures the silicone pad by fastening it to the thermal block. The assembly can be turned up to 90 degrees resulting in the turning of the containers from an upright position to a horizontal position, a position in which the distance through which sublimation must progress is drastically reduced so as to greatly enhance the efficiency of the lyophilization process.
