An apparatus for processing battery electrodes includes: a microwave applicator cavity with slots on opposite ends to allow a continuous sheet to move through the cavity in a first direction; a processing chamber constructed of microwave-transparent material, disposed within the applicator cavity and surrounding the continuous sheet, the processing chamber having slots to allow the continuous sheet to pass through it; a microwave power supply to deliver power to the applicator cavity; a source of heated gas providing a controlled gas flow through the processing chamber in a direction opposite the first direction; and, at least one non-contacting temperature measuring device positioned to measure a surface temperature at a selected location on the continuous sheet as it passes through the processing chamber. The apparatus is particularly suited for removing polar solvents from porous electrode coatings. A related method is also disclosed.

Disclosed is an acoustic head for indirectly drying a material, the acoustic head including at least one ultrasonic transducer facing the material, the material having a first side, and a second side, the second side opposite the first side, the second side defining a surface to be dried, the ultrasonic transducer positioned facing the first side; and an air delivery unit positioned facing the first side of the material.

A system and method is provided for drying for fibers or fibrous materials, such as flax, hemp, jute, sisal, banana and coir, among others by dehumidifying the fibers in a temperature and humidity-controlled environment. The dehumidification system does not detrimentally affect the fiber's properties (e.g., strength) by evenly drying the fibers and not subjecting the fibers to repeated high temperature environments, allowing the fibers to be used in more biocomposite applications, such as a reinforcement material. Also the dehumidification method reduces/prevents fiber discoloration, odor, and decomposition.

A modular furnace, in particular for the oxidative stabilization of a carbon fiber starting material comprising a cuboidal furnace chamber, on the upper face of which first deflecting rollers are arranged in a mutually spaced and parallel manner and on the lower face of which second deflecting rollers are arranged in a mutually spaced and parallel manner such that the carbon fiber starting material runs upwards and downwards in a laterally adjacent and slightly spaced manner so as to meander vertically in the area of the furnace chamber. A carbon fiber inlet locking device and a carbon fiber outlet locking device are provided on the upper face of the furnace chamber, and an air guiding device is connected to the furnace chamber. A supply air portion of the air guiding device is connected to a vertical air inlet side of the furnace chamber, and a discharge air portion of the air guiding device is fluidically connected to a furnace chamber vertical air outlet side opposite the vertical air inlet side. The air guiding device has an air drive device between the supply air portion and the discharge air portion.

Disclosed herein relates to an electrode sheet drying device including a guide roller having a plurality of perforated holes formed on the outer circumferential surface, and the guide roller is configured to vacuum cling an electrode sheet to prevent an electrode sheet from being lifted from the guide roller during a drying process, thereby having an effect of mitigating the occurrence of creases in a non-coated part and preventing lifting of a current collector and the occurrence of cracks.

Dryers (300) comprising a first surface (102) and a deflector (302). The first surface comprises at least one opening (104) through which air is forced during use to dry a printed media and the deflector comprises (302) a second surface to change the direction of airflow passing through the at least one opening. The deflector guides the direction of the airflow such that it flows substantially in a direction corresponding to the direction of travel (310) of the printed media.

A method for producing a wet-laid nonwoven fabric web includes the following steps: providing a fibrous web of industrially generated inorganic fibers, or fibers from synthetically generated polymers, and thermally drying the fibrous web in an alternating manner by infrared radiation and hot air, in order for the nonwoven fabric web to be generated.
