  • Patent number: 11054185
    Abstract: A carrier for supporting containers such as syringes or cartridges in a lyophilization chamber during lyophilization of substances contained therein, comprises a base assembly with an array of holes for receiving the containers. Each hole includes a heat-conductive metal portion for engagement with lower parts of the container held therein and a relatively non-conductive polymeric portion surrounding a portion of the container above the lower portion for enhancing the vertical growth of relatively large ice crystals. An upper part of the carrier supported above the base assembly includes a plunger-holding plate for frictionally holding elastomeric plungers and a pusher plate movable toward the plunger-holding plate and having protrusions for pushing the plungers out of the plunger-holding plate and into the containers before the containers are removed from the chamber.

  • Patent number: 10907897
    Abstract: A device for drying organic substances under vacuum and altered temperature conditions, e.g. to extract particulates from the substance without significant damage to the substance. The device can contain a hollow vacuum oven to dry the organic substance. The substance is placed on the shelves in the vacuum chamber and the heaters below the shelves maintain the temperature uniformity to evenly heat the substance on the shelf. A vacuum feedthrough is connected on one side of the shelf for desired flow of the substance and the shelves themselves can be tilted for even drying. The vacuum pump, which can be used in high vacuum mode or gas flow mode then removes the particulates that evaporated from the substance and the condenser collects and condenses the unwanted or wanted particulates.

The storage hopper is connected to a molding machine. A control valve is disposed between neighboring two of the initial dryer, the vacuum drying hopper and the storage hopper and controls the falling amount of the granular or powdery plastic material. In addition, a hot air steam device is connected to the initial dryer and provides the high-temperature hot air to enter the initial dryer. A vacuuming device is connected to the vacuum drying hopper and vacuums the gas from the vacuum drying hopper. Because the initial dryer, the vacuum drying hopper and the storage hopper are combined into the vertical form and cannot be moved, the ground area occupied by the drying apparatus is smaller so that the optimization spatial availability is obtained.

The manual elevating mechanism couples with a basket for accommodating wastes by using a hanging rope, and the shielding cover is fixed below the suspension mechanism and in a moving path of the basket. The basket is moved to a storage tank containing water in which radioactive wastes are stored, and the radioactive wastes are pumped into the basket by means of a pump. The basket is then lifted above a water surface of the storage tank and received in the shielding cover, and then the shielding cover is moved into a water holder so as to drain waters in the basket. The basket is further moved onto a heating seat to be heated and a vacuum equipment is started to dry the radioactive wastes.

  • Publication number: 20140310975
    Abstract: A coalescing dryer passes air downwardly through items to be dried in a container. The air can be diverted to change direction following passage of the air through the items to be dried. The moving air causes liquid on the surface of items to be dried to coalesce and travel downwardly and from the items being dried. A vacuum dryer applies a vacuum to the container of items to be dried when placed in a vacuum chamber after pre-drying by the coalescing dryer so as to evaporate liquid in the items to be dried that has not been removed by the coalescing dryer.

  • Publication number: 20140283408
    Abstract: A vacuum assisted dehydration system including a vacuum chamber, a gas compressor, a heating coil, and a vacuum pump is provided. A sealing member removably attached to an opening of the vacuum chamber is opened to introduce one or more instruments into the vacuum chamber. The gas compressor, in fluid communication with the vacuum chamber, recirculates a pressurized gas into the vacuum chamber. The heating coil within the vacuum chamber heats the recirculating gas, which contacts the instruments positioned therein and transfers heat energy into interstitial cavities and to surfaces of the instruments or onto other moist components, for example, hands to vaporize moisture present therein. The vacuum pump, in fluid communication with the vacuum chamber, creates a negative gas pressure in the vacuum chamber to exhaust the vaporized moisture entrained in the heated recirculating gas from the vacuum chamber to dehydrate the instruments or the moist components.
