In a press area, a wet paper is pressed against a heating surface to heat the wet paper with a conveying surface to conveying the wet paper to form a pressure regulating gap between the heating surface and the conveying surface. The pressure regulating gap is provided in a size less than a thickness of the wet paper and more than a thickness of recycled paper to be produced therefrom.

A process for combusting a high-moisture fuel to generate steam in which the high-moisture solid fuel is first dried by contacting with an oxygen-depleted gas stream while being heated by indirect heat exchange with a recirculating thermal fluid. The dried fuel is then combusted with a combustion air stream to produce a combustion products stream whose heat first is used to generate steam, and then to preheat the combustion air stream by indirect heat exchange in which a portion of the combustion air stream and/or a portion of the combustion products stream bypasses the heat exchanger. The combustion products stream also provides heat to dry the solid fuel via the recirculating thermal fluid.

A system can be used to process liquid materials, such as aqueous-based syrup solutions containing sugar molecules. In some examples, the system includes a processing vessel having multiple individually-controllable temperature zones arranged in series. In operation, an aqueous solution can be introduced into an inlet port of the processing vessel and passed sequentially through the series of temperature zones. Water from the aqueous solution can be evaporated within the initial stage(s) of the processing vessel to form a concentrated solution that is then cooled in subsequent stage(s). Accordingly, a supersaturated solution may be formed from the aqueous solution in the processing vessel that is then solidified to subsequently form a substantially dry solid material (e.g., sugar), still within the processing vessel. The substantially dry solid material can discharge through an exit port of the processing vessel.

The present disclosure relates to a towel maintenance device for storing and keeping a towel and for heating and drying the towel stored and kept therein. The towel maintenance device—provides a structure in which heated air flows in a first staying space formed in a heat transfer plate and heats the heat transfer plate, thereby allowing a textile product such as a towel and the like in contact with the heat transfer plate to be heated based on thermal conduction, and the heated air discharged through a communicating hole of the heat transfer plate is discharged while passing through the textile product such as a towel and the like or flows around the textile product such as a towel and the like, thereby allowing the product to be dried to be heated based on convection. The towel maintenance device according to the present disclosure enables entire objects to be dried to be rapidly heated and dried.

A freeze drying plant for drying products containing liquid has a vacuum chamber configured to receive the products. A reception device has at least one reception plate onto which the products can be applied. A cooling system has a fluid circuit configured to cool and/or to heat the products by a cooling fluid conducted in the fluid circuit. The reception plate has at least one closed fluid space that is connected to the fluid circuit and that cooling fluid flows through. At least one sound generator introduces ultrasound into the products during a drying phase, with the sound generator disposed in the fluid space and being able to be flowed around by cooling fluid.

Thermal energy is supplied to a fluid mixture on a substrate that has a first component, for example water, and a second component, for example cosolvent, such that the proportion of the second component in the fluid mixture is increased at relatively high temperatures of the fluid mixture. It may thus be reliably produced that an optimally small quantity of the second component is located on the surface of the substrate following the drying process.

The present disclosure provides a condensing plate. The condensing plate comprises a body. The body comprises a first face and a second face opposite to the first face. The first face is provided with a condensing part and a solvent storage structure. The solvent storage structure is configured to store a solvent and release, along a direction away from the second face, gas formed by the solvent after evaporation.

A substrate processing apparatus comprises: a first chamber; a liquid film former which forms a liquid film P of a solution containing a sublimable substance having sublimability on a surface of a substrate in the first chamber; a second chamber 30 which receives the substrate W having the liquid film; a plate unit 311 provided in the second chamber such that the substrate W is placeable on an upper surface thereof; a temperature controller 312, 335 which controls a temperature of the upper surface of the plate unit 311 to a predetermined temperature; and a heater 322 which heats and sublimates the sublimable substance precipitated from the solution on the substrate W placed on the plate unit 311.
