  • Patent number: 10724795
    Abstract: The object of the invention is a horizontal paddle dryer that is used for normal or vacuum drying of soaked substances that are in the form of dry powder mixtures or granulates in a manufacturing process and are soaked and mixed (normally with solvents) due to technological needs. Once drying is completed, the interior of the dryer needs to be washed due to various types of substances that differ from each other in content and properties. The construction of the horizontal paddle dryer of the invention allows simple and effective washing of the horizontal paddle dryer without an additional removal of washing heads during the washing of the dryer.

  • Patent number: 10633784
    Abstract: A heat pump clothes dryer comprising a circulating air path consisting of a drying drum and a drying air path for circularly flowing drying air; and a heat pump system consisting of an evaporator, a throttling device, a condenser and a compressor successively connected end to end for circularly flowing a refrigerant medium. The condenser and the evaporator are disposed on the drying air path, and perform heat exchange with the drying air. The compressor has independent suction compression chambers, each suction compression chamber being switchably connected in series or in parallel. When the dryer starts drying in a low-temperature environment, the suction compression chambers of the compressor operate in a parallel state, so that the air displacement of the compressor is increased to improve the flowing activity of the refrigerant medium in the heat pump system, so as to avoid occurrence of frosting of the evaporator.

  • Publication number: 20120073157
    Abstract: An apparatus for torrefaction of water containing cellulosic materials is performed in an inert atmosphere. The cellulosic material is cascaded through the apparatus between a plurality of rotatable trays vertically stacked within multiple processing zones. Steam being generated from heating of the cellulosic material is recycled back to the apparatus to provide an inert atmosphere. The steam may be superheated in a heat exchanger. Exhaust from the torrefaction zone of the apparatus has some moisture and other volatiles removed prior to being reheated in a burner. The heated exhaust is used in the heat exchanger to superheat the recycled steam.

  • Patent number: 8137440
    Abstract: A dryer and a drying apparatus attachable to a dryer are disclosed. A wheel having desiccant material is located in line and in close proximity with a heating element. The wheel includes a first portion positioned in an inlet air path and a second portion positioned in an outlet air path. The desiccant material removes water molecules from air within the inlet air path, and lowers the vapor pressure of the incoming air. In the outlet air path, heated air flows through the second portion to transfer energy to the desiccant material. The wheel rotates to change the desiccant material within the portions.

  • Patent number: 8133327
    Abstract: Provided is a substrate processing method that prevents generation of watermarks on a substrate and can be performed at a low cost. The method controls the ambient humidity around the substrate depending on the kind of the chemical liquid, when the substrate is processed with the chemical liquid. The control of the humidity is performed at least in a drying step that dries the substrate W. In one embodiment, the ambient humidity around the substrate is controlled when a fluid containing IPA as a drying fluid is supplied to the substrate W after processing the substrate W with the chemical liquid.

  • Patent number: 7765813
    Abstract: The present invention is an apparatus and process for cooling and de-steaming hot calcined stucco used in the production of gypsum boards or bagged plaster. The apparatus is a fluid bed stucco cooler and comprises a cooler housing having a plenum having a stucco inlet and stucco outlet. The stucco cooler includes a rotating disk in the plenum. The rotating disk includes nozzle for spraying fluid, and is attached to a rotable shaft extending from the side of the cooler also includes a fluidization pad and agitator to help to mix the air and the stucco powder to insure fluidization, prevent channeling, and prevent the stucco powder from building up on the various components. The air also forces steam from the hot calcined stucco out through an air outlet located at the top of the stucco cooler, thereby de-steaming the stucco. The stucco flows through the plenum and passes over the cooling coils, thereby cooling the stucco as it reaches the stucco outlet.
