Abstract: A dryer and a foreign material removing apparatus thereof are provided. The foreign material removing apparatus includes a case; a first filter housed in the case; and a second filter disposed downstream from the first filter based on a direction of air flow in the case, the first filter and the second filter performing a relative motion with respect to each other.

Abstract: A device for drying laundry by means of a current of air includes a drum to accommodate the laundry and a ducting system to direct the current of air. The ducting system has a section arranged downstream of the drum in which a filter is arranged to capture lint from the current of air. A scraper is movably mounted over the filter. This filter is a channel arranged in an approximately horizontal manner and in the form of an inverted arch. The scraper has a foil resting on the filter in a sprung manner, the scraper being curved in accordance with the shape of the channel. Moving the scraper along the longitudinal axis of the filter scrapes lint off the filter and into a collection reservoir.

Abstract: A hydrogen peroxide vapor generation unit (10) receives hydrogen peroxide and water solution at an interface (20) and interconnects with an air dryer (14) by way of nipples (72, 92). In one embodiment, the dryer includes a clamping assembly (42) which is latched (74, 94) with the nipples and which receives a disposable desiccant cartridge (40). In an alternate embodiment, a reusable desiccant cartridge (40?) is connected directly to the nipples (72, 92). When the desiccant cartridge (40?) is saturated, it is removed and placed in a regenerator unit (120). A regenerated cartridge is installed in its place.

Abstract: A device for holding substances during drying comprising a flask having a structure defining an opening. A pair of contiguous or juxtaposed filters is disposed in the opening. A freeze-drying assembly comprising a freeze-drying apparatus, and the device disposed in the apparatus for holding substances during freeze-drying processing. A method for processing a substance under sterile conditions comprising disposing a substance in a flask, positioning the flask in a drying apparatus, and passing a drying medium through a pair of juxtaposed filters for drying the substance.

Abstract: An air drying cartridge for use in an air drying system is disclosed. The air drying cartridge comprises a telescoping casing resiliently self adjustable in height which has an inner cylindrical apertured wall and an outer cylindrical apertured wall. The inner apertured wall has a facing surface, an upper end and a lower end. The outer apertured wall has a facing surface, an upper end and a lower end. The facing surface of the inner apertured wall is disposed to face the facing surface of the outer apertured wall thereby defining an opening therebetween. The air drying cartridge also includes a porous filter liner, a pair of sealing caps and a moisture absorbing material for extracting moisture from air flowing through the air drying cartridge. The porous filter liner is situated adjacent to each of the facing surfaces within the opening. One of the pair of sealing caps affixes to the upper ends of the apertured walls and another affixes to the lower ends of the apertured walls.

Abstract: A desiccant cartridge for use in a compressed air system comprising, a perforated stainless steel casing, a polyester felt support liner disposed against the inner surfaces of the perforated stainless steel casing, a pelletized moisture-absorbing material situated within the polyester felt support liner, and a pair of rubber cup-shaped end caps molded to the ends of perforated stainless steel case so that moisture vapor is extracted from compressed air passing radially the desiccant cartridge.
