Systems and methods for drying or bonding materials are described. A material to be dried or bonded may be passed through a through air dryer (TAD) or through air bonder (TAB). Some of the air output by the TAD/TAB may be recirculated to be passed back through material. As the air is recirculated, it is heated and mixed to a desired uniform temperature distribution. As heated air of the desired uniform temperature distribution is passed through ducting for transport to the material, the desired uniform temperature distribution deteriorates due to heat loss experienced at the walls of the ducting. Heating tape is implemented with respect to particular locations of ducting and selectively operated to maintain air traveling through the ducting at the desired uniform temperature distribution. Heat generated by the heating tape is used to counteract heat loss experienced by air traveling through the ducting.

An air blowing device is numerically controllable. An air blowing device includes a feed base, a nozzle base arranged at a distal end of the feed base, a spindle housing arranged in the nozzle base, a spindle rotatable about a rotation axis, a nozzle block including a first nozzle, and a first fluid channel for feeding dry air to the first nozzle and including a first main pipe, a first annular channel, a first connecting tube, and a first communication channel communicating with the first annular channel and the first nozzle.

A dryer device for drying plastics pouches, the device comprising a main air admission pipe having a plurality of dryer heads including outlet orifices, each outlet orifice forming an air knife, the dryer heads being associated in pairs so as to define a plurality of passages for plastics pouches, each passage being adapted to dry plastics pouches passing therethrough by applying two opposing air knives.

A water extraction facility comprising a suction box having a suction opening and a chamber (9) arranged above the suction opening by means of a connector (21) and a perforated sheet metal element (24) creating head loss is mounted in the connector (21).

Apparel drying assemblies including a housing having an internal passage, at least one outlet, and external mounting members, projections mounted to the external mounting members and having an inlet, at least one outlet, and positionable to receive an apparel; a valve element positioned between the internal passage of the housing and the inlets of the plurality of projections; and a source of pressurized air in the housing. The projections are adapted to contact and deflect the valve element when the projections are pivotally rotated so that the pressurized air passes through the projections to dry the apparel mounted on the projections. The projections may be elongated, extendable projections. Methods of drying apparel, apparel dryer supports, dryer nozzles, dryer nozzle assemblies, and apparel drying activation mechanisms are also disclosed.

A seed drying system for positioning a manifold in a seed treater includes a seed treater that contains a plurality of seeds that have been coated with a liquid treatment. A manifold is positioned within the seed treater and a fan is provided to selectively urge air. The fan is fluidly coupled to the manifold to direct the air over the seeds thereby facilitating the liquid treatment to dry on the seeds. A mounting unit is provided and the manifold is coupled to the mounting unit such that the mounting unit retains the manifold in a horizontal orientation. The mounting unit is releasably coupled to the housing such that the manifold is retained in the drum. Moreover, the mounting unit centrally positions the manifold in the aperture.

Provided are a surface drying device for a sheet-like non-permeable base material with enhanced drying efficiency on a surface of a sheet-like non-permeable base material having a liquid adhering to a surface thereof, and a printing apparatus and a printing method using the surface drying device. The surface drying device for a sheet-like non-permeable base material includes: a loading port for loading a sheet-like non-permeable base material with a liquid adhering surface; an air nozzle configured to spray high-temperature air; an unloading port for unloading the sheet-like non-permeable base material; an air shield zone forming portion, which is formed between the loading port and the unloading port, and is configured to form a heat-insulating air shield so as to cover the liquid adhering surface of the sheet-like non-permeable base material; and a retained air exhaust portion configured to exhaust retained air retained on the liquid adhering surface of the sheet-like non-permeable base material to outside of the air shield zone forming portion through use of a Coanda effect, to thereby replace liquid adhering surface air on the liquid adhering surface of the sheet-like non-permeable base material.

A method for producing a flame-proofed fiber by performing a flame-proofing treatment on a carbon-fiber precursor fiber bundle with a heat treatment furnace including a gas supply blowout nozzle, including: a nozzle body including an inclined plate that guides a gas flowing straightly from a gas inlet port to a rectification board; and the rectification board which rectifies the flow of the gas to blow out toward a yarn from a gas outlet port, where a gas introduction direction in the nozzle is different from a gas blowing out direction, a gas guiding zone is between the inclined plate and the rectification board and includes a guide plate in a space between the gas inlet port and the rectification board and divides the gas supplied from the inlet port into two or more streams, and at least one of between the inclined plate and the guide plate or between the guide plates, an upstream passage width W1 perpendicular to a gas flowing direction inside the gas passage and any downstream passage width W2 satisfy W1W2.

A substrate processing apparatus includes a substrate rotating unit 11 configured to hold and rotate a substrate 3; a processing liquid supplying unit 13 configured to supply a processing liquid to the substrate; and a replacement liquid supplying unit 14 configured to supply, to the substrate, a replacement liquid with which the processing liquid supplied from the processing liquid supplying unit is replaced. While the replacement liquid supplying unit 14 supplies the replacement liquid to the substrate, the processing liquid supplying unit 13 supplies the processing liquid to a position on the substrate positioned at an outer peripheral side thereof than a supply position of the replacement liquid to form a liquid film of the processing liquid. It is possible to maintain a state in which the entire surface of the substrate is covered with the liquid film without increasing consumption amount of the replacement liquid.
