The freeze dryer is particular in that the gas transfer line (20), which comprises the cooling device (22), is separated from the gas pump (18) at least by the condensation chamber (16), the condensation chamber (16) providing a gas passage for the withdrawn vapor gas during the withdrawal in the first gas flow direction, and a gas passage and/or gas storage for the flushing gas during the conveying in the second gas flow direction.

A drying system for drying an agriculture product is disclosed. The drying system includes an enclosure having one or more wall structures and defining a chamber for receiving and storing the agricultural product. Each wall structure includes an inner wall having a plurality of wood panels and an outer wall. Each wood panel is a treated wood panel and is adapted to absorb moisture from an air circulating inside the chamber. Each wood panel is treated with a solution of calcium chloride to enhance a moisture absorbing capacity. The outer wall is disposed substantially parallel and spaced apart from the inner wall and defines a gap therebetween. The enclosure further includes one or more moisture absorbing materials disposed inside the gap to absorb moisture received from the inner wall.

Disclosed herein is a novel medical implement drying apparatus and a method for holding and drying certain medical implements during a reprocessing sequence. This is accomplished by forcing air through the apparatus. The apparatus and method disclosed herein is useful for many medical implements having a hollow casing. The medical implement drying apparatus is particularly well suited for use with a drying cabinet containing one or more of the medical implements during the drying process which will facilitate drying of the exterior of each medical implement, while the disclosed apparatus removes water and water vapor from the interior of each medical implement. Specialized holders, racks, and drying gas pumping systems are also disclosed.

A drying system and apparatus that includes a drying apparatus having a housing having opposite open ends, a plurality of sequentially spaced fans contained within the housing, and a cover member for covering an open end of the housing with the cover member containing a plurality of openings that are in communication with an interior of the housing. The drying system also includes a kit containing various components for drilling into cabinetry or similar enclosed structures and connecting the drying apparatus to the openings that are drilled into the cabinetry or similar enclosed structures.

The present disclosure provides a method for regulating an inert gas flow in a crystal pulling furnace, a method for preparing monocrystalline silicon, and monocrystalline silicon. The method for regulating an inert gas flow includes introducing the inert gas into a main furnace chamber of the crystal pulling furnace from an auxiliary furnace chamber of the crystal pulling furnace, and regulating a flow direction of the inert gas flow introduced into the auxiliary furnace chamber of the crystal pulling furnace.

A system and method for drying and utilizing spent grain includes an agitation device having an elongated semi-cylindrical mixing chamber with a motor-driven shaft and a plurality of agitators. A lid is hingedly positioned along the top end of the chamber and is connected to the dehumidification system by a pair of air ducts.
