This invention relates to a novel device for converting sunlight to heat, which is used to dehydrate solid organic material, which thereby is made useful as low - grade solid fuel or partly dehydrated foodstuffs.

The present invention provides an apparatus particularly useful for the dehydration of organic materials, and a process of dehydration using the apparatus of the invention. The apparatus includes a drying enclosure to receive and contain materials to be dehydrated, a cooling section with a first stage cooling coil and a second stage cooling coil to remove moisture from a drying fluid by condensation, a heating section with a first stage heating source and a second stage heating source controllab...

A material to be dehydrated wrapped in a semipermeable sheet is dipped in a dehydrating solution to cause part of water contained in the material to be absorbed into the dehydrating solution to dehydrate the material, and the water-absorbed dehydrating solution is cooled and concentrated to adjust its temperaure and concentration, and sterilized as needed, to be used repeatedly for the dehydration treatment, thereby dehydrating a large amount of material to be treated without changing the qualit...

A dehydration plant for dehydrating food products, including a microwave kiln (2), conveyor means (3) for conveying food products through the kiln (2), circulation means (21, 6) for circulating air through the kiln (2), refrigerated dehumidification means (7, 11) for dehumidifying the air to be circulated through the kiln (2), and heating means (12, 13, 14) for heating the air to be circulated through the kiln (2) such that food products conveyed through the kiln (2) are exposed to both microwav...

A method of dehydrating gases using N-alkyllactams is described. Included are steps for the recovery of any entrained vapors of the N-alkyllactams from the dehydrated gas streams and the recirculation of the recovered lactams thus reducing the operating cost of such process.

Dehydrated compositions are obtained by: combining a hydrous composition, e.g., a hydrous electrolyte salt, with inert fluorochemical liquid; heating the resulting mixture in a vessel to volatilize water and inert fluorochemical liquid therein until the water content of the mixture is reduced to a desired level; optionally treating the resulting dehydrated mixture with another chemical material, e.g., a polar organic solvent; and optionally subjecting the dehydrated mixture or the treated dehydr...

A dehydration device is provided which consists of a portable framework. Structures are for suspending from the portable framework various components of turnout uniforms that are used by fire and rescue personnel. A mechanism is coupled to the portable framework for removing moisture in an accelerated time interval from the various components of the turnout uniforms.

Novel prosthetic nuclear implants for insertion into vertebral discs are prepared by dehydrating hydrated bulky hydrogel discs under specific conditions so as to reduce the water content as low as possible (down to about 10% by weight) but without distortion of the implants, without the formation of concavities and sharp edges, and without changing the shape of the hydrated implant.

A dehydration machine includes a stuff tank, a stuff inlet provided at a lower portion of the stuff tank, a stuff outlet provided at an upper portion of the stuff tank, and a pair of drums each having a circumferential wall with a plurality of water passage apertures, the pair of drums being juxtaposed in the stuff tank. The pair of drums rotate adversely about its respective axis so as to introduce stuffs in the stuff tank therebetween from a lower side thereof. One of the drum is rotatable in ...

Dehydration catalysts for vicinal diols prepared by forming an intimate mixture of finely divided solid particles of at least one pyrophosphate and at least one acid orthophosphate of at least one metal belonging to the group consisting of lithium, sodium, strontium and barium into a formed mass which is thereafter calcined to transform the acid orthophosphate into pyrophosphate resulting in a catalyst having superior mechanical properties.
