  • Method and system for freeze-drying injectable compositions, in particular pharmaceutical compositions
    Patent number: 10670336
    Abstract: Methods and systems for freeze-drying injectable compositions, in particular pharmaceutical compositions, are provided whereby a freeze-dried composition may thus obtained by the method and systems. The systems for freeze-drying injectable compositions, in particular pharmaceutical compositions, make use of the method as described by storing a quantity of a dispersion of an injectable composition in an aqueous dispersion medium in at least one ready-to-use vial, cooling the vial to form ice crystals, applying a vacuum, and applying thermal heat to the dispersion while rotating the vial to homogeneously supply heat to the vial. The condition of the drying dispersion in the rotating vial is measured using an optical sensor using electromagnetic detection and adaptively controlling the amount of thermal heat.

  • Device and method for drying grain
    Patent number: 10591212
    Abstract: A device for drying grain includes a housing having an inlet port and an outlet port, a first passageway, a second passageway, a grain flow housing, a filter across the grain flow housing, a recovery column, an air supply, a recycle column, a filter cleaner in the recovery column, and a conveyor for moving the filter cleaner along the filter. The air supply pulls an air flow into the housing through the inlet port as a grain flow pours through the grain flow housing. The air flow passes through the grain flow in a first pass air flow from the passageways to dry the grain. The first pass air flow passes through the filter to remove particles, and a portion of that filtered first pass air flow is recycled back with the filter cleaner to dislodge particles clogging the filter. The other portion is vented through the outlet port.
