An electrohydrodynamic (EHD) drying apparatus includes a non-uniform electric field resulting from an electric field source operable for a high potential, and an electric field source operable for a low potential. A power source is connected to the electric field sources for producing the non uniform electric field for inducing dielectrophoresis (DEP) in an article within the uniform electric field. In particular configurations, the applied non-uniform electric field is for separating a vapor phase being formed during drying from the liquid phase. The electric field source defines a polarizer adapted to produce dielectrophoresis, and the electric field induces coupled electrostatics and momentum for disposing liquid towards the high electric field for drying.

The invention relates to a drying method for polyglycollide warp-knitted support meshes for artificial skin, specifically comprising: pre-drying, deep drying, and fabric stress relaxation, which are performed sequentially. The drying method can completely remove water in polyglycollide warp-knitted support meshes as well as solvents left during the cleaning process, and can effectively maintain the properties such as tensile strength, pore size, and weight of the polyglycollide warp-knitted support meshes, thus being of great significance for the application of the polyglycollide warp-knitted support meshes in the field of medical artificial skin.

Microwave dryer of a print system with modulation of the microwave source using FSK. In one embodiment, a microwave dryer includes a microwave source coupled with a waveguide. The waveguide transports electromagnetic energy to dry wet colorant applied by a printer to print media. The microwave source provides the electromagnetic energy at an operating frequency. The microwave dryer also includes a processor coupled with an FSK modulator that modulates the operating frequency of the microwave source. The processor determines a modulating signal with a modulating frequency based on a period of time for the print media to traverse the waveguide, and applies binary values that represent the number of frequencies to an input of the FSK modulator to cause the FSK modulator to output the series of discrete frequencies over the period of time to vary intensity positions of the electromagnetic energy across the width of the print media.

To perform a flame-resistant treatment on a precursor fiber strand by sending hot air to a heat treatment chamber (2) through a hot air blowing nozzle (4) in a direction parallel to a running direction of a precursor fiber strand (10). The hot air blowing from the hot air blowing nozzle (4) passes through a porous plate and a rectifying member that satisfy the following conditions (1) to (4), wherein the conditions are set as follows: (1) A/B≧4.0; (2) 0.15≦α≦0.35; (3) 0≦B−d≦20; and (4) 80% or more of an area of one opening of the porous plate when causing facing surfaces of the porous plate and the rectifying member to overlap each other is included in one opening of the rectifying member, A indicating a hot air passage distance (mm) of the rectifying member, B indicating a horizontal maximum distance (mm) of one opening of the rectifying member, α indicating a rate of hole area of the porous plate, and d indicating an equivalent diameter (mm) of the porous plate. Accordingly, it is possible to provide a parallel stream type flame-resistant heat treatment furnace having exhibiting the uniform heat transfer performance throughout the inside of the heat treatment chamber by preventing the blockage of the nozzle caused by a silicone compound generated inside the heat treatment chamber even in the hot air blowing nozzle having a simple structure.

The liquid ink comprises a solvent portion and a dry content. The arrangement comprises at least one nozzle configured to generate a stream of gas over said area with a gas stream velocity and/or gas stream shape, such that an evaporation rate of the solvent portion of the liquid ink is increased and a rate of change of velocity of the gas stream propagation increases with a distance normal to a direction of a gas flow and is maximized over the surface of the substrate and the deposited ink.

A method of drying print agent is disclosed. The method comprises blowing hot air onto an absorbent printable medium that bears water- and/or solvent-based print agent to reduce the viscosity of the print agent and to promote absorption of at least some water and/or solvent in the print agent by the printable medium; and, subsequent to the blowing of hot air, irradiating the printable medium with ultraviolet radiation to dry the unabsorbed portion of print agent on the printable medium. A printer ink drying apparatus and a print apparatus are also disclosed.
