  • Patent number: 9255732
    Abstract: A dryer includes a sealed drum, a heat pump system, a vacuum device and a steam generating device. The steam generating device connects with the interior of the drum to introduce hot steam into the interior of the drum. The vacuum device connects with the interior of the drum. The heat pump system is arranged external to the drum. Heat generated by the heat pump device is exchanged with the outer surface of the drum through a liquid medium so as to heat the wet clothes in the drum. Simultaneously, damp-hot air mixed with the water vapor in pumped from heating clothes in the drum by the vacuum device and the hot steam pumped into the drum and contacted with clothes are cooled and condensed into water. The water produced by damp-hot air is connected with water provided by the steam generating device.

  • Patent number: 9046206
    Abstract: A gas supply device has an air compressor, a liquid-gas separator, and a freeze-drying mechanism. The air compressor discharges high-pressure gas with a high temperature and containing a liquid to the liquid-gas separator. The high-pressure gas separated by the liquid-gas separator then enters the freeze-drying mechanism for cooling. The freeze-drying mechanism has a drainer for removing water in the high-pressure gas. The removed water goes through a drain line to the liquid-gas separator to be discharged. The liquid in the liquid-gas separator has a cooling effect.

  • Patent number: 8978265
    Abstract: A bandage/diaper drying device includes a gas inlet and channels formed between two layers of a very thin material (e.g. plastic). A spiral tube is positioned between the two layers to reduce occlusion of the layers and maintain flow of gas from the inlet to vents that are directed to a potential source of moisture. The vents are formed on a peripheral distribution channel that is in fluid communication with the gas inlet. In a preferred embodiment, each vent has a one-way duckbill valve allowing for the flow of gas from the peripheral distribution channel to dry a diaper/bandage in which the bandage/diaper drying system is mounted. The one-way duckbill valves reduce backflow of foreign matter into the peripheral distribution channel.

  • Publication number: 20150068055
    Abstract: A vertical plastic material drying apparatus having an initial dryer, a vacuum drying hopper and a storage hopper, which form a vertical combination. 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.

  • Patent number: 8756826
    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: 20140157619
    Abstract: Systems and methods are described for conductively heated vacuum-based drying of portable electronic devices. For example, a portable electronic device that has been exposed to excessive liquid is placed inside a drying chamber. The drying chamber is closed and a drying routine commences. During the drying routine, the chamber is pressurized to a vacuum level sufficient to gasify liquids inside the device, and the device is conductively heated at least to replace latent heat of vaporization lost during the pressurization. Some embodiments include techniques relating to payment processing, monitoring and feedback control, decontamination, and/or other functionality.

  • Patent number: 8745891
    Abstract: A vacuum kiln apparatus and method of using same are disclosed for use in drying corn, other grains, seeds and legumes. The vacuum kiln apparatus can include a support base, a wall, a vacuum pump system, a pressure valve, a top hatch, a machinery access hatch, an anti-overload baffle, a conveyor system, a motor, a chamber vent valve, an air outlet manifold and an air compressor. The wall defines an internal chamber for receiving the grain. The vacuum pump system is used to draw down the pressure within the internal chamber which drives moisture out of the corn while maintaining the integrity of the corn, i.e., drying the corn with little or no cracking. The air outlet manifold along with the air compressor are used to flush high pressure air through the piles of corn to strips off any residual water that may be clinging onto the exterior of the corn grains.

  • Publication number: 20140059879
    Abstract: This work is in simplifying the freezing and heating process required for a typical lyophilization process. From a liquid nitrogen supply tank called LIN tank, calculated quantity of vaporized nitrogen is transported the use point where a heater that uses heating media heats up nitrogen to a desired temperature and pass into the annular space of the steel plate where lyophilized solvent such as water of solvent is deposited on the outer surface of the plate. The heated nitrogen temperature will dictate the rate at which the solvent or water will be thawed. This unique process offer simplicity, safety and ease operation allowing the user to avoid heating oil as heating media, a common practice in the industry.
