  • Patent number: 9004079
    Abstract: Disclosed is a substrate processing apparatus capable of drying a substrate to be processed while suppressing the pattern collapse or the occurrence of contamination. A substrate is held in a liquid bath while being immersed in a liquid, and the liquid bath is disposed in a processing space of a processing vessel. A processing of drying the substrate is performed by replacing the liquid in the liquid bath with a supercritical-state fluid. A predetermined mechanism moves liquid bath between a processing location in the processing case and a stand-by location outside the processing case. A heater installed in the processing case changes the fluid to a supercritical state or maintains the supercritical state while cooling mechanisms cool down the liquid bath moved to the stand-by location outside the processing vessel.

  • Patent number: 7938271
    Abstract: This consists of the preparation of powdered still slops from concentrated liquid still slops dried and converted into a powder in a conventional dryer (1) and then fed to a powder collecting cyclone (4), featuring at the lower outlet aperture of the collecting cyclone (4) a circular or snail-shaped or logarithmic spiral-shaped device (7) fed with a cool, dry air draught which generates a downward suction effect counter to the upward suction effect of the collecting cyclone (4), bringing about the falling and separation of the powder from the draught of hot air which carries the same. The cool, dry air carries the powder to the exterior for bagging, and the hot air exits upwards via the collecting cyclone (4) towards the flue (6), using a device for the recovery of the heat which it still bears as much as possible.

  • Patent number: 7886457
    Abstract: An apparatus for cooling bulk material with a grate flowed through by cooling gas. The apparatus comprises a plurality of planks configured to move forward and back in the direction of conveyance and, between the planks, a sealing device having spatially separate outer and inner sealing elements. The sealing device has between the sealing elements a conveying duct, which runs along the length of the planks and on which a gas supply is configured to produce a gas stream along the length of the conveying duct. Bulk material which has infiltrated through the outer sealing element can be transported away before it can reach and migrate through the inner sealing element. The accompanying sealing effect can considerably reduce the undesirable material through-fall, while enabling the use of low-wearing seals, which provide excellent wear resistance.

  • Patent number: 6578287
    Abstract: A method and apparatus is disclosed for staging or cooling a substrate between high temperature thermal processing steps. In the disclosed embodiment, one or more cooling stations are located off-line within a wafer handling chamber, outside the thermal processing chamber. After thermal processing, a hot wafer can be loaded on to one station, where the wafer is subjected to forced convection cooling. In particular, the wafer is subjected to cooling gas from above and below through perforated upper and lower showerhead assemblies. The wafer can thus be cooled rapidly on a station while other wafers are transferred into and out of the processing chamber. Desirably, the wafer is cooled on the station to a point at which it can be handled by a low temperature wafer handler and stored in a low temperature cassette.

  • Publication number: 20030101617
    Abstract: An automatic clothes dryer has a drying cycle followed by a cool down cycle where the cool down cycle is terminated when the sensed output temperature of the dryer drum falls below a default temperature value preselected or altered by user. This permits the user to adjust the termination cool down cycle temperature to the user's preference and touch sensitivity to the warmth of clothing removed from the dryer. The user adjusts the setting of a user variable selection device on the dryer control panel to a preferred temperature signal representing the desired temperature of articles in the dryer when the cool down cycle is terminated. The dryer has a comparator that is connected to the outlet thermistor for receiving the sensed signal representing the temperature of the air leaving the drum and that is connected to the user variable selection device for receiving the user preferred temperature signal.

  • Patent number: 6560896
    Abstract: Apparatus, method and system for the treatment of a wafer. After a treatment at elevated temperature, a wafer is taken out of the reactor in question with the help of a mechanical transport apparatus which preferably grips the wafer around the circumference and on the under side and consists of a wafer surrounding ring. The wafer is then placed in a floating wafer reactor where it is cooled in a controlled manner. Transport for further action or treatment then takes place.

  • Publication number: 20030061729
    Abstract: A method and apparatus for drying long fibre hay. A first step involves providing round bales of long fibre hay. A second step involves separating the bales to form a loose mass of long fibre hay. A third step involves feeding the loose mass of long fibre hay into a rotary dehydration drum. A fourth step involves separating the loose mass of long fibre hay from air containing entrained moisture by passing the long fibre hay through a cyclone separator with a first stream of air passing to an exhaust and a second stream of the loose mass of long fibre hay passing into an air lock. A fifth step involves cooling the loose mass of long fibre hay. A sixth step involves passing the loose mass of long fibre hay through a hay baler, whereby the loose mass of long fibre hay is formed back into bales.

A wafer cassette configured for supporting multiple wafers is submerged in a first processing fluid within a container, which is installed on the base plate for insertion into the pressure vessel. Vessel inlet and outlet tubes extend vertically downward from the ceiling of the pressure vessel to nearly the base plate. Container inlet and outlet tubes extend vertically downward from the ceiling of the pressure vessel to inside the container and nearly to the bottom of the container.

    Abstract: A water-driven jet or venturi extraction means is used to remove, capture and cool the hot, highly humid air created within commercial dishwashers during a wash rinse or sanitization cycle. A cold water spray is used to create a pressure reduction zone which serves to draw in hot, highly humid air from the dishwasher. Water vapor cools and condenses on contact with the cold water spray within the venturi. The invention also serves to help vent the dishwasher. Cool, fresh air is drawn into the dishwasher while the hot air is drawn into the venturi.
