A nozzle box (7, 7) is arranged in a drying device in a transverse direction relative to a board (8) to be dried by means of drying air in the drying device. The nozzle box (7, 7) has a tapered shape in at least one direction perpendicular to the direction of flow of the drying air in the nozzle box (7, 7) and a drying surface provided with nozzles (18) and facing the board (8), wherein the drying air streams out of a plurality of nozzles (18) arranged in rows in the drying surface onto the board (8). The nozzle box (7, 7) is characterized in that the ratio of the sum of the openings of the nozzles (18) per square meter to the drying surface is less than 1.1%.

Drying device for drying hygroscopic material, for example wood, has a drying chamber for accommodating material to be dried, and air conditioning for setting a drying climate in drying chamber during drying process. Air conditioning sets drying climate, at least in part, as a function of moisture of material to be dried. There are bar-like support devices for storing material to be dried in drying chamber during drying process. At least one bar-like support device has scale for measuring weight of material to be dried that is stored on support device. Scale is in signal transmission connection with a control apparatus designed and programmed so that moisture of material to be dried is determined from weight measured by scale. Control apparatus is designed and programmed for controlling air conditioning so drying climate is set as a function of moisture of the respective material to be dried, as determined from the weight measured.

A locker includes a pair of upstanding sidewalls and at least one compartment defined between the upstanding sidewalls. A drying compartment includes upper and lower horizontal panels, at least one of the upper and lower panels being hollow and extending at least partially between the sidewalls. A pair of compartment sidewalls are connected to the panels, at least one of the compartment sidewalls being in fluid communication with the at least one hollow upper and lower panels. A perforated rear panel is connected to the compartment sidewalls and the upper and lower panels and is in fluid communication with an interior of the drying compartment. A fan is disposed in one of the compartment sidewalls. The fan draws air from at least one hollow upper and lower panels, directs it into the interior of the drying compartment, and the air is exhausted from the compartment though the perforated rear panel.

In one aspect of the present disclosure is a method of contactlessly urging, directly, or moving a substance on the surface of a substrate, the method employing a gas knife configured to produce a gas curtain having parallelogram flow.

The present invention relates to a dryer for treating a moving printing web in a rotary printing press with gas, having a nozzle body. The dryer according to the invention is characterized in that the nozzle body has at least one opening for the exit of heated gas and has at least one opening for recirculating the cooled gas.

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.

An air knife for discharging a stream of gas onto a sheet of material. The air knife includes a main body including an inlet portion and an outlet portion, and a plurality of inlet ports. The inlet portion defines a plenum. The outlet portion defines an exit orifice in fluid communication with the plenum. The inlet ports project from the inlet portion and each inlet port comprises a passageway in fluid communication with the plenum. In some embodiments, the inlet ports project from a rear, or trailing, wall of the main body. In other embodiments, the outlet portion terminates at an exit face in which the exit orifice is formed, with a tip region of the outlet portion forming a taper angle of not more than 90 degrees in extension to the exit face.

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 plurality of modular units are connected together on a slightly sloped drainage field with a perforated header pipe at the lower side conveying water away from the drainage system. An impermeable flexible liner cushioned on both sides is located below the modular units. The modular units are each made up of rigid boxes that have connecting cross slots at the bottom thereof and vertical perforations there through. The rigid boxes are lined with a drainage fabric that is site specific and have an expanded geosynthetic material therein, which is held in place when filled with porous granular material. High flexural strength mats are connected together over the tops of the modular units. An air inlet pipe connects air to the cross slots, down the sloped drainage field, to the header pipe to drain water from the bulk granular material resting on the high flexural strength mats. Some of the modular units have a pneumatic vibrator connected to a source of pressurized air. The entire system may be quickly disassembled, moved to a different location, and reassembled with the number of modular units being changed according to the circumstances.
