An apparatus for extracting a vaporizable substance, from a material containing such substance, comprises an irradiation chamber for irradiating the material with electromagnetic radiation to vaporize the substance. The substance may comprise water and the material is dehydrated. The electromagnetic radiation comprises microwaves. The irradiation is conducted in the near-field range of the electromagnetic radiation. In one aspect, the electromagnetic radiation within the waveguide evanescently couples with the material.

L'objet de l'invention est un procédé de traitement de graines de fruits à coques, notamment de cerneaux de noix, de noisettes, caractérisé en ce qu'il comprend une étape de dépelliculage comprenant un traitement thermique de la pellicule de l'amande concernée suivie immédiatement d'un traitement mécanique. L'invention couvre aussi le dispositif associé comprenant un bâti (10) avec un convoyeur général (12), un module (14) d'alimentation, un module (16) de traitement thermique et/ou texturant, un module (18) de traitement mécanique, et un module (20) de traitement aromatisant. L'invention couvre enfin le produit alimentaire obtenu constitué d'amandes de fruits à coques, dépelliculées et croquantes à coeur ou moelleuse à coeur, aromatisées ou non, grillées extérieur ou non, pour l'apéritif et le grignotage.
摘要:
Die Erfindung betrifft ein Verfahren zur Herstellung tiefgefrorener Kräuter. Grundsätzlich sind die Hersteller von Nahrungsmitteln und dgl. immer bestrebt, Verbesserungen ihrer Produkte zu erreichen. Bei Kräuter ist es immer wünschenswert, ihre Elastizität und Aroma zu erhalten, ihre Haltbarkeit zu verlängern und gleichzeitig die mikrobiologische Belastung der Kräuter deutlich zu reduzieren. Dieses erreicht das erfindungsgemäße Verfahren dadurch, daß die Kräuter in ein leicht kompaktes Gebilde mit einem speziellen Gewicht von 0,01-0,5 g/cm 3 gebracht werden und in der Mikrowelle ggf. unter gleichzeitiger Kühlung und Sauerstoffausschluß behandelt werden, und zwar in einem Temperaturbereich von - 20 bis
摘要:
A bulk material processor (10) includes a tray assembly (18) with a panel subassembly (78) having an upper panel section (80a) and a lower panel section (80d). The upper panel section (80a) is adapted to receive bulk material (12) and pass it to the lower panel section (80d) for discharge. A heater panel (12) is mounted over the tray assembly (18) for radiantly heating the bulk material (12) passing thereunder. A vibrator (20) is coupled to the tray assembly (18) for vibrating the bulk material (12) whereby it advances along the tray assembly (18). A control system (23) is provided for controlling the operation of the vibrator (20) and for controlling the output includes cascading the bulk material (12) from an upper panel section (80a) to a lower panel section (80d) by vibration and subjecting it to infrared radiation.

Die Erfindung betrifft ein Verfahren sowie eine Vorrichtung zum Quellen, Dämpfen oder Extrahieren und anschließenden Trocknen von schüttfähigen Stoffen in loser Form, unter Anwendung von Mikrowellenenergie. Die schüttfähigen Stoffe werden in einem geschlossenen Behälter (1) zunächst mit Dampf unter Überdruck zum Quellen bzw. Dämpfen, oder Lösungsmittel zum Extrahieren, ausgesetzt und anschließend in demselben Behälter unter Anwendung von Vakuum unter Mikrowellenenergie getrocknet, wobei die Stoffe durch ein Mischwerk (16) laufend umgewälzt werden.
摘要:
SUMMARY A device (100) is described for disinfestation and improvement of the preservability of foodstuffs of vegetable origin, a method for disinfestation of foodstuffs and a method for improvement of the preservability of foodstuffs. The device comprises a reverberating cavity (12) wherein the foodstuffs are made to pass, means (5) of generating electromagnetic waves at microwave frequency, radiation means (4) coupled to said microwave generating means (5) to beam the microwaves inside said reverberating cavity (12) and mode mixing means or stirrers (10) disposed inside said reverberating chamber (12) to mix the electromagnetic wave modes.
摘要:
Disclosed are methods for treating a ready-to-eat cereal base fabricated from an oat containing cereal composition to increase the stability of the product. The methods comprise the step of subjecting the cereal base to a high intensity microwave field (>150 V/cm) for about 5 to 45 seconds. The treated cereal pieces exhibit superior stability and also improved flavor resulting from 'interior' toasting of the cereal base.
