Disclosed is an apparatus for drying a component transferred in a reel-to-reel method. The apparatus for drying a component transferred in a reel-to-reel method includes an uncoiler and a recoiler, both for transferring the component, a drying chamber disposed between the uncoiler and the recoiler and drying the component, wherein the drying chamber includes an inner space, a transfer roller for transferring the component; an infrared drier for irradiating infrared light toward the component, and a hot air supplier for supplying hot air between the infrared drier and the component.

A feeding device is provided for a belt drying installation for dump or sewage sludge material dewatered down to a pasty consistency. In the conveying path of the sludge material, a first roller having transverse grooves that are set back relative to the outer diameter of the roller and a guide device are arranged relative to the outer diameter of the first roller such that when the roller is rotated the sludge material is drawn into the transverse grooves and is shaped to elongated extrudates. The first roller is associated with a comb which has teeth that rigidly engage the transverse grooves and which sweeps the extrudates from the transverse grooves, wherein the tips of the teeth which rigidly engage the transverse grooves define a line of engagement. The tooth tips which rigidly engage the transverse grooves are beveled towards the tooth neck.

In one example, a multi-stage hot air dryer in which each successive stage is configured to take in air discharged from a prior stage and discharge it on to an article moving through the dryer from the last stage to the first stage such that the article is exposed to higher humidity air first in the dryer and to lower humidity air last in the dryer.

The application relates to a method and apparatus for manufacturing a natural fiber based staple fibers. The application further relates to the staple fibers, staple fiber based raw wool and products comprising such. A method comprises providing a cellulose suspension (101, 310, 510) including water, refined cellulose fibrils and at least one rheology modifier, directing the cellulose suspension through a nozzle (102, 320, 520) onto a surface (300, 400, 500), drying the cellulose suspension onto the surface (103, 300, 400, 500) for forming a fiber (350, 550), and cutting the cellulose suspension on the surface for forming staple fibers (105).

Disclosed herein is a treatment unit for treating a continuously through-flowing elongate windable element, wherein said unit includes a substantially sealed enclosure for containing a gaseous environment, the enclosure having an inlet port for the continuous ingress of an elongate windable element and an outlet port for the continuous egress of treated elongate windable element, treatment apparatus located within the enclosure, for treating the elongate windable element therein, and a spatial loading system located within the enclosure, for continuous collection of the elongate windable element within the enclosure, and for conveying the elongate windable element from the inlet port to the outlet port.

A drying device includes a plurality of guide rollers and a heater. The plurality of guide rollers is configured to contact a liquid applied face of a drying target object that is conveyed with liquid applied to the liquid applied face, while the drying target object is dried. The plurality of guide rollers includes at least one guide roller having a surface roughness of from 2 to 8. The heater is configured to heat the drying target object while the plurality of guide rollers guides the drying target object. A printer includes a liquid application device configured to apply liquid to a drying target object, and the drying device.

Disclosed embodiments describe a reconstructed filament comprising natural protein fibrils and an additive. Disclosed embodiments also describe a wool comprising: a plurality of staple fibers formed of reconstructed filaments, wherein the reconstructed filaments comprise natural protein fibrils and an additive. Disclosed embodiments also describe a yarn spun from staple fibers, the yarn comprising: staple fibers comprising reconstructed filament, wherein the reconstructed filament comprises natural protein fibrils and an additive.

Microwave dryers and a method of fabricating microwave dryers are disclosed. The microwave dryers include a microwave source that generates electromagnetic energy to dry a wet colorant applied to a continuous-form print medium. The microwave dryers further include a microwave waveguide electromagnetically coupled to the microwave source that transports the electromagnetic energy between a first end and a second end. The microwave waveguide includes a passageway that is sized to pass the continuous-form print medium through the microwave waveguide. The microwave dryer further includes a plurality of microwave absorbing elements within the microwave waveguide that absorb the electromagnetic energy and heat the wet colorant.

Disclosed embodiments describe a method for manufacturing a staple fiber based on natural protein fiber. The method may include: providing a protein suspension, the protein suspension comprising fibrils of the natural protein fiber; directing the protein suspension through a nozzle onto a surface for forming a protein based fiber; drying the protein suspension on the surface; extracting the fiber from the surface; and providing the staple fiber. Disclosed embodiments may further describe a fiber based raw wool. The raw wool may include staple fibers, wherein the staple fibers are reconstructed on the basis of protein fibrils and are mechanically subdivided from natural protein fibers, wherein the protein fibrils are interlocked by hydrogen bonds, and wherein the raw wool comprises an unoriented, entangled, fluffy network of staple fibers.
