Description

Descrizione “Modulo di riscaldamento a raggi infrarossi per apparecchi di riscaldamento, cottura e grigliatura cibi ed alimenti in genere.” Description "Infrared heating module for heating, cooking and grilling appliances and foods in general."

Il trovato è applicabile nelle apparecchiature per la cucina sia professionale che domestica, si prefigge di ottenere il massimo rendimento ed efficienza con un tempo breve per il riscaldamento, cottura e grigliatura di cibi e derrate alimentari di vario genere, mantenendo comunque il cibo non a contatto diretto con la fonte di calore, cioè cottura indiretta per irraggiamento del calore, ovvero con emissione di raggi infrarossi a onde corte e medie. The invention is applicable in both professional and domestic kitchen equipment, it aims to obtain maximum performance and efficiency with a short time for heating, cooking and grilling foods and foodstuffs of various kinds, while keeping the food out of contact. direct with the heat source, i.e. indirect cooking by radiation of heat, or with the emission of short and medium wave infrared rays.

I sistemi attuali adottano resistenze corazzate oppure resistenze a filamento di tungsteno che hanno una inerzia termica elevata, raggiungendo la massima temperatura di funzionamento in tempi abbastanza lunghi, ed anche l efficienza è bassa . Current systems adopt armored resistors or tungsten filament resistors which have a high thermal inertia, reaching the maximum operating temperature in a fairly long time, and also the efficiency is low.

Per ottenere tempi di accensione e messa in pieno regime rapidi si è adottato un sistema basato sul utilizzo di lampade alogene infrarosse, installate all’interno di un contenitore che in parte focalizza ma distribuisce e rende uniformi i raggi infrarossi emessi, utilizzando dei riflettori in alluminio, ai quali è sovrapposto uno strato isolante in materiale ceramico, inoltre nella parte inferiore dove vengono emessi gli infrarossi è posto una lastra in vetroceramica lavorata con un procedimento di sabbiatura. A system based on the use of infrared halogen lamps, installed inside a container that partially focuses but distributes and makes uniform the infrared rays emitted, has been adopted to obtain rapid ignition and start-up times, using aluminum reflectors. , to which an insulating layer of ceramic material is superimposed, furthermore in the lower part where the infrared rays are emitted there is a glass-ceramic plate worked with a sandblasting process.

Tutto il sistema è applicato in orizzontale, ma è anche possibile applicarlo in verticale, comunque con la distanza regolabile rispetto al cibo, per esempio nella parte superiore mobile di un sistema di cottura chiamata salamandra FIG.1, ma anche in forni grill, oppure in sistemi girarrosto e similari. The whole system is applied horizontally, but it is also possible to apply it vertically, however with the adjustable distance from the food, for example in the mobile upper part of a cooking system called a salamander FIG. 1, but also in grill ovens, or in rotisserie systems and similar.

In particolare nella FIG.1 si evidenzia 1 la parte mobile della salamandra che avvicinandosi o allontanandosi dalla parte inferiore dove è posto il cibo si ha una prima regolazione della intensità del calore, con 2 il vetroceramico sabbiato, con 3 la parabola concentratore , con 4 l'isolante ceramico, con 5 la scatola metallica che contiene e allinea il tutto e infine con 6 sonda termostatica di protezione. In particular, in FIG. 1 the movable part of the salamander is highlighted 1 which, approaching or moving away from the lower part where the food is placed, gives a first adjustment of the intensity of the heat, with 2 the sandblasted glass ceramic, with 3 the concentrator parabola, with 4 the ceramic insulator, with 5 the metal box that contains and aligns the whole and finally with 6 thermostatic protection probe.

Claims

Claims: 1 - Device in a single module characterized by the fact that it has a high efficiency, that it can be placed horizontally or vertically, due to the particular solutions of both the reflectors and the arrangement of the insulators and the protective glass ceramic. 2 - Device in a single module as in claim 1, with external metal container 1 provided with suitable holes for cooling and which acts as a support and containment of the internal components. 3 - Device in a single module as per claims 1 and 2, where in the lower part it is equipped with a glass-ceramic plate 2 sandblasted to reduce the glare effect and serves as a protection for the lamps, it also allows easy cleaning. 4 - Device in a single module as per claims 1 to 3, inside which are positioned one or more aluminum reflectors 3 equipped with a support 3a for fixing them, which can be covered with a further glossy aluminum film , these have the function of both a support for the lampholders, but above all they concentrate and uniform the infrared emission. 5- Device in a single module as per claims 1 to 4, in which an insulating layer of ceramic material 4 is placed in the upper part, which takes the shape of the rear part of the reflectors, obtaining the insulation function that further reflection infrared. 6 - Device in a single module as per claims 1 to 5, which in the upper part provides a thermostatic probe 5, which in case of excessive temperature disconnects the power supply to the halogen lamps, protecting the whole device from breakage. 7- Device in a single module as per claim from 1 to 6, device placed in a separate container or housing with the function of an electromechanical regulation of the power by switching the number of lamps powered; alternatively, an electronic board is provided that regulates the power by varying the on and off times of the power supplied to the lamps.
