Description
DESCRIZIONE Il presente trovato ha per oggetto una macchina per la tostatura e/o l'essiccazione di prodotti alimentari in grani, quali caffè, riso, nocciole, mandorle, arachidi, pistacchi, pinoli, caratterizzata dal fatto che comprende una camera di tostatura e/o essiccazione, DESCRIPTION The present invention relates to a machine for roasting and / or drying food products in grains, such as coffee, rice, hazelnuts, almonds, peanuts, pistachios, pine nuts, characterized in that it comprises a roasting chamber and / or drying,
un corpo allungato ad asse verticale disposto entro tale camera ed avente una pista elicoidale destinata ad essere percorsa dai grani di prodotto, an elongated body with vertical axis arranged within said chamber and having a helical track intended to be traversed by the product grains,
mezzi per far vibrare il corpo intorno al suo asse, cosi da provocare l'avanzamento dei grani lungo la pista, means for vibrating the body about its axis, so as to cause the grain to advance along the track,
un'apertura superiore per l'alimentazione del prodotto entro la camera, ed un'apertura inferiore per la fuoriuscita del prodotto dalla camera, an upper opening for feeding the product into the chamber, and a lower opening for the product to escape from the chamber,
un primo ventilatore per far circolare l'aria entro la camera ed un secondo ventilatore per espellere aria, umidità e fumi dalla camera, e mezzi per provocare un riscaldamento dei grani entro la camera. a first fan for circulating the air inside the chamber and a second fan for expelling air, humidity and fumes from the chamber, and means for causing a heating of the grains inside the chamber.
Un vantaggio principale derivante dalla struttura sopra descritta consiste nel fatto che la lunghezza del percorso lungo il quale il prodotto è soggetto al riscaldamento può essere anche notevole senza per questo comportare un rilevante ingombro della macchina. A main advantage deriving from the structure described above consists in the fact that the length of the path along which the product is subjected to heating can also be considerable without thereby entailing a significant encumbrance of the machine.
Un ulteriore vantaggio risiede nel fatto che i grani di prodotto sottoposti al trattamento, nel loro avanzare lungo la pista elicoidale, sono soggetti ad una continua rotazione su sè stessi per cui il trattamento di cottura e/o essiccazione viene eseguito uniformemente nelle varie zone dei grani. La miscelazione del prodotto in lavorazione è inoltre preferibilmente favorita mediante pareti deviatrici e/o scalini disposti lungo la pista elicoidale. A further advantage lies in the fact that the grains of the product subjected to the treatment, in advancing along the helical track, are subject to continuous rotation on themselves so that the cooking and / or drying treatment is carried out uniformly in the various areas of the grains . The mixing of the product being processed is also preferably favored by means of diverter walls and / or steps arranged along the helical track.
Secondo una forma d'esecuzione del trovato, i suddetti mezzi di riscaldamento sono costituiti da almeno una sorgente di raggi infrarossi e, preferibilmente, da una pluralità di lampade a raggi infrarossi portate da una struttura di sostegno all'interno della camera. Le lampade a raggi infrarossi vengono collocate negli spazi compresi fra le varie spire della pista elicoidale portata dal rotore vibrante, cosi da coprire con i loro raggi tutta la pista percorsa dal prodotto. According to an embodiment of the invention, the aforesaid heating means consist of at least one infrared ray source and, preferably, a plurality of infrared lamps carried by a support structure inside the chamber. The infrared lamps are placed in the spaces between the various turns of the helical track carried by the vibrating rotor, so as to cover with their rays the entire track traveled by the product.
Grazie alla suddetta caratteristica, si ottengono tempi brevissimi di torrefazione e nello stesso tempo si realizza, grazie all'adozione del corpo vibrante con pista elicoidale, un procedimento continuo. Thanks to the aforementioned characteristic, very short roasting times are obtained and at the same time, thanks to the adoption of the vibrating body with helical track, a continuous process is achieved.
Secondo un'ulteriore caratteristica di una preferita forma d'esecuzione del trovato, sono previsti mezzi per la regolazione del moto vibrante del corpo recante la pista elicoidale, il che permette di sottoporre all'azione dei raggi riscaldanti il prodotto nel tempo voluto, secondo le necessità di trattamento. According to a further characteristic of a preferred embodiment of the invention, means are provided for regulating the vibrating motion of the body bearing the helical track, which allows the product to be subjected to the action of the heating rays in the desired time, according to the need for treatment.
Inoltre è previsto un sistema di regolazione dell'intensità di calore fornita dalle lampade a raggi infrarossi, il che permette di regolare il trattamento in funzione del quantitativo di prodotto da trattare. Ècosi possibile, ad esempio, regolare le lampade in modo tale da mantenere costante la temperatura che il prodotto deve raggiungere. È previsto in particolare l'impiego di sensori atti a misurare l'intensità della vibrazione, la temperatura nei vari punti della camera e nelle lampade infrarosse, nonché di un circuito elettronico a microprocessore per l'ottimizzazione del processo di trattamento. Furthermore, a system for regulating the intensity of heat provided by the infrared lamps is provided, which allows to regulate the treatment according to the quantity of product to be treated. For example, it is possible to adjust the lamps in such a way as to keep the temperature constant that the product must reach. In particular, the use of sensors designed to measure the intensity of the vibration, the temperature in the various points of the chamber and in the infrared lamps, as well as a microprocessor electronic circuit for the optimization of the treatment process is envisaged.
Il trovato verrà ora descritto con riferimento al disegno annesso, illustrato a puro titolo di esempio non limitativo, che si riferisce ad una vista schematica in sezione di una macchina secondo il trovato. The invention will now be described with reference to the attached drawing, illustrated purely by way of non-limiting example, which refers to a schematic sectional view of a machine according to the invention.
Il numero di riferimento 1 indica nel suo insieme un basamento di sopporto su cui è montato in modo da poter vibrare intorno ad un asse verticale 2 un corpo cilindrico 3 provvisto di una pista elicoidale 4 che è destinata ad essere percorsa dai grani di prodotto. Il corpo 3 è disposto all'interno di una camera 5 delimitata da una parete 6 costituita da pannelli termo-isolanti. Nel basamento 1 sono contenuti mezzi di comando (non illustrati) per impartire al cilindro 3 ed alla pista elicoidale un moto vibratorio interno al suo asse 2. In tal modo, i grani di prodotto che vengono alimentati all'interno della camera 5 tramite una tramoggia 6a ed un'apertura superiore di ingresso 7, vengono costretti ad avanzare lungo la pista elicoidale 4 fino ad arrivare ad un'apertura inferiore di scarico 8. Lungo il percorso, i grani di prodotto sono riscaldati da una pluralità di lampade a raggi infrarossi 9 (una sola delle quali è visibile nella figura) sopportate da una struttura di sostegno 10 disposta all'interno della camera 5 e situate negli spazi compresi fra le spire successive della pista elicoidale 4. La macchina comprende inoltre un ventilatore 12 per espellere aria, fumi ed umidità dalla camera 5, attraverso condotti 13, 14. The reference number 1 indicates as a whole a support base on which a cylindrical body 3 equipped with a helical track 4 which is intended to be traversed by the grains of product is mounted so as to be able to vibrate around a vertical axis 2. The body 3 is arranged inside a chamber 5 delimited by a wall 6 consisting of heat-insulating panels. The base 1 contains control means (not shown) for imparting to the cylinder 3 and to the helical track a vibratory motion inside its axis 2. In this way, the product grains which are fed into the chamber 5 through a hopper 6a and an upper inlet opening 7 are forced to advance along the helical track 4 until they reach a lower discharge opening 8. Along the way, the grains of product are heated by a plurality of infrared lamps 9 (only one of which is visible in the figure) supported by a support structure 10 arranged inside the chamber 5 and located in the spaces between the successive turns of the helical track 4. The machine also comprises a fan 12 for expelling air, fumes and humidity from chamber 5, through conduits 13, 14.
La macchina è inoltre preferibilmente provvista di almeno una resistenza elettrica aiettata 15 portata da un sostegno disposto all'interno della camera 5. Le resistenze elettriche 15 vengono utilizzate per essiccare il prodotto, quando non è necessario procedere alla tostatura tramite le lampade 9. Naturalmente, anche le resistenze 15 sono regolabili, in modo da consentire l'adattamento alle caratteristiche del prodotto. The machine is also preferably provided with at least one finned electric resistance 15 carried by a support placed inside the chamber 5. The electric resistances 15 are used to dry the product, when it is not necessary to proceed with toasting through the lamps 9. Of course, the resistances 15 are also adjustable, so as to allow adaptation to the characteristics of the product.
L'utilizzazione dei ventilatori 11, 12 consente di stabilizzare ad un livello uniforme la temperatura interna della camera 5 e The use of the fans 11, 12 allows to stabilize the internal temperature of the chamber 5 and at a uniform level
