Abstract: The present invention is intended to artificially break pit membranes in cell membranes of cells constituting wood and then to readily attain dryness of the wood. In view of the fact that one pit or the other pit of pits in the form of a pair is blocked with the torus 1 in felled wood to cause poor removal of water in cells, it is intended to prevent the blockage of the pit membrane, i.e., to break the pit membrane per se, thereby facilitating easy escapement of water in cells after the breaking. In the present invention, wood fuel is burned, and subject wood is allowed to stand in a treatment chamber filled with smoky wood gas generated by the combustion for a predetermined period of time, to expose the subject wood to far-infrared radiation and components contained in the wood gas.

Abstract: Drying a coated substrate which includes magnetic particles includes a condensing surface spaced from the substrate. This creates a longitudinal gap between the substrate and the condensing surface. Liquid is evaporated from the substrate to create a vapor and the vapor is transported to the condensing surface without requiring applied convection. The vapor is condensed on the condensing surface to create a condensate which is removed from the condensing surface. Removal is performed, using more than gravity, without allowing non-uniformities of the condensate film to occur. The magnetic particles are oriented on the coated substrate by subjecting the coated substrate to a magnetic field created at a location outside of the dryer space.

Abstract: A material drying apparatus having a sealable chamber for receipt of wet material, such as clothing. In this embodiment clothing placed into the chamber is dried upon the evacuation of air from the chamber wherein moisture drawn from the clothes is condensed on a condensate coil placed in the chamber. Heating coils placed around the chamber elevate the temperature to enhance condensate operation providing an energy efficient material dryer requiring no make-up air. Condensed water is purged after the drying process although provisions provide for an interim purge should excess liquid be drawn from the material.

The openings in the gas distributor containing axially positionable bolt assemblies which may be alternately loosened or tightened to regulate gas flow into the fluidizing chamber without having to empty the reactor.

Abstract: A combination drying unit has a towel roll rotatably held within a housing. An air blower, powered by a motor, is also held within the housing. The motor provides a stream of air from the air blower through an opening in the housing. The motor also powers, via an appropriate transmission unit, a guide roller, which engages a towel stream and dispenses the stream through a second opening. A sensor detects a towel outage within the device and communicates, in appropriate fashion, the towel outage condition.

Abstract: A method and a facility for dehydrating plants, particularly for dehydrating forage. The method consists in introducing the forage to be dehydrated in a drier with a retention time and a temperature that are suitable to achieve the at least partial drying of the leaves of the forage. The forage, when it leaves the drier, is subjected to an operation for separating the leaves from the stalks, and the leaves and stalks thus separated are then subjected, separately from each other, to additional treatments that include at least one additional drying for at least one of the two components constituted by the leaves and the stalks.

Abstract: A dryer for drying dental models includes a solid base member, a top member, a variable plurality of modular drying units, each of which includes a frame and a slidable, foraminous tray, an air blower and an articulated support arm. In use, the modular drying units are positioned in an over-and-under stacked relation, such that the slidable trays therein form a column of trays. Each slidable tray contains a central aperture and a duct extending upward from the perimeter of the central aperture. The aperture and duct in the center of each tray collectively form a channel running through the center of the column of trays. The base member is fixedly connected to the articulated support arm, which supports the dryer. The top member, which is positioned on top of the uppermost modular drying unit, includes a central aperture with an inlet tube inserted therein and exhaust vents around the perimeter of its top surface for the release of air.

Abstract: A steam blast box for applying steam to a web of paper conducted over a roll of a paper machine. The box has a closed steam blast chamber which extends along the roll transverse to the direction of travel of the web and to which steam can be fed. The front wall of the box, which faces the roll, has a plurality of steam outlet openings. A steam propagation space is formed between the front wall of the steam blast box and the roll. For controlling the temperature and/or for regulating the amount of heat transferred to the web of paper in the steam propagation space, an air outlet channel, which extends transverse to the direction of travel of the web and is located at the web inlet end of the steam propagation space, is provided for the admixing of air in the steam. In this way, sensitive separate, zone-wise control of the heating of the paper web can be obtained. The steam propagation space can be cooled zone-wise by feeding air on the inlet side.

Abstract: The present invention provides a method and apparatus for separating volatile components from a base material. Specifically, the apparatus comprises a gas tight reactor, an induction heating vessel, a plate and evacuating means for evacuating volatile components from the reactor. The method comprises the steps of heating the material from which the volatile components are to be removed by induction heating in a gas tight vessel. More specifically, the area surrounding the object within the gas tight vessel is filled with metal filings which are then heated by induction heating. The metal filings thus inductively heat the object, causing any volatile components therein to be released. The volatile components are then evacuated from the gas tight vessel and the metal filings removed.

Abstract: Drying of a solid polymer is disclosed in which a solid polymer obtained by polymerization (or a product of modification of the solid polymer) is contacted with a drying gas so that any solvent and/or unreacted polymerization feed materials remaining in the solid polymer are removed to thereby dry the solid polymer, and in which a gaseous polymerization feed material is used as the drying gas and contacted with the solid polymer to thereby dry the solid polymer (step i), and the resultant solid polymer is contacted with a drying gas which contains an inert gas (step ii). The drying gas can be recovered from the step (i) and part thereof can be recycled through a polymerization step as it is or be recycled, after cooling the drying gas to thereby remove any condensed components, to the step (i). Not only can the solid polymer be efficiently dried but also the solvent and unreacted polymerization feed materials recovered from the solid polymer can efficiently be recycled by the disclosed method.

Abstract: A cooler/dryer includes a housing for storing bulk product including a bulk product inlet at the top of the housing and a grid structure adjacent the bottom of the housing for discharging bulk product. The grid structure is movable between open and closed positions and, in both positions, primary air flows upwardly through the grid structure to cool and/or dry the bulk product. Auxiliary air inlet ducts are located above the grid structure for flowing auxiliary air into the product bed. The primary air and the auxiliary air combine in the product bed to increase the cooling and/or drying effect without substantially increasing the velocity of the primary air through the grid structure which would otherwise affect the discharge rate of the product through the grid structure.
