Abstract: A method is described for enhancing mass and heat transport of fluids in a fine pore structure through an appropriate modulation of the fluid pressure. For example, in an air drying process for a porous material that contains liquid, the air pressure is modulated throughout the volume of the drying chamber.

As an example, this method can be used for rapid drying of any open porous substances ranging from small pored materials such as aerogels and xerogels, to larger pored substances or articles such as industrial articles, agricultural articles (e.g., densely stacked vegetables, coffee beans, hops and other grains), paper-based products, thin films, pharmaceuticals, cloth, and clothing.

Abstract: A first gas nozzle and a second gas nozzle are fixedly provided in the vicinity of the forward end of a nozzle arm. The nozzle arm is rotated along a locus R while a substrate rinsed with deionized water is rotated, for discharging nitrogen gas from the first and second gas nozzles. Visible moisture is loosely expelled from the upper surface of the substrate by spraying the nitrogen gas from the first gas nozzle, and moisture slightly remaining on a fine pattern or the like can also be completely removed by spraying the nitrogen gas from the second gas nozzle to the same region of the substrate as that sprayed with the nitrogen gas by the first gas nozzle. Consequently, the surface of the substrate can be stably and reliably dried. Thus, a substrate processing apparatus capable of stably and reliably drying the surface of the substrate is provided.

Abstract: A method and apparatus for coating and drying coated substrates without introducing significant surface imperfections while running at higher web speeds than known drying methods. The substrate is preferably coated within the drying enclosure or the coating bead may form a closure at the entrance of the drying enclosure. The substrate is moved through a first drying enclosure along a first axis. The first drying enclosure is substantially isolated from an external environment. A first low velocity, substantially laminar flow field of a drying gas is directed across the front surface of the substrate. The first flow field is generally parallel to the front surface and generally perpendicular to the first axis to minimize the formation of surface imperfections during the evaporation of the coating solvent. The substrate may then be moved to subsequent drying enclosures through transition enclosures that minimize surface imperfections due to high velocity interaction between the adjacent drying enclosures.

A plurality of linear actuators control the operation of the doors.

Abstract: By enhancing the natural instabilities in the boundary layer and in the free shear layer of a wall jet, the boundary is minimized thereby increasing the transport of heat and mass. Enhancing the natural instabilities is accomplished by pulsing the flow of air that creates the wall jet. Such pulsing of the flow of air can be accomplished by sequentially occluding and opening a duct that confines and directs the flow of air, such as by rotating a disk on an axis transverse to the flow of air in the duct.

Abstract: A continuous-flow grain steeping and slow grain cooling process and apparatus. The continuous charging of hot, partially dried grain from a heated-air dryer into the top of a grain container in a layer of approximately uniform thickness is accomplished by use of grain spreading equipment. The downward flow of grain through the grain container is regulated by thermostatically controlled sweep and discharge augers located in the bottom of the bin. The grain flows at a rate that allows the grain to remain in a top steeping zone for a predetermined period of time, typically from four to twelve hours. After the initially charged grain is held at the steeping temperature for a predetermined steeping time, a continuous upward flow of ambient air is provided by a fan to cool the grain in a bottom cooling zone. The air flow is controlled by a thermostat to provide air flow at a rate that allows grain to remain in the cooling zone for a predetermined cooling time which is dependent on the airflow rate in cfm/bu.

Abstract: A continuous-flow, slow grain cooling process including the charging of hot, partially dried grain from a heated-air grain dryer into the top of a grain container in an even layer. The downward flow of grain through the grain container is regulated at a rate that allows the grain to remain in a top steeping zone for from four to twelve hours. After the initially charged grain is held at the steeping temperature for a predetermined steeping time, a controlled upward flow of ambient air is provided to cool the grain in a bottom cooling zone. The air flow is provided at a rate that allows grain to remain in the cooling zone until it is cooled close to the ambient air temperature, but the upward flow is controlled such that it will not cool any grain until it has been properly steeped. Cooled dry grain from a layer near the bottom is then discharged from the bottom of the grain container.

A drying operation includes a drying step in which hot air is supplied into the drum and a cooling step in which the heater is deenergized. An intermittent operation is initiated upon completion of the drying operation. The intermittent operation is completed when the temperature sensed by the temperature sensor has reached a predetermined value set for preventing occurrence of creases in the clothes.
