Description

Dispositif d'épluchage automatique à l'aide d'une mesure par sonde à ultra sons Automatic peeling device using ultrasonic probe measurement
La présente invention concerne un dispositif d'épluchage automatique de fruits et légumes, de toutes tiges végétales ou de tubercules, dispositif applicable aussi bien dans l'industrie que dans le domaine domestique.The present invention relates to an automatic peeling device for fruits and vegetables, all plant stems or tubers, a device applicable both in industry and in the domestic field.
A la connaissance du demandeur, les technique faisant appel à des ultra sons ne sont pas utilisées pour l'épluchage des fruits et légumes.To the knowledge of the applicant, the techniques using ultrasound are not used for peeling fruits and vegetables.
Le dispositif selon l'invention est illustré sur les figures 1 à 3 annexées :The device according to the invention is illustrated in Figures 1 to 3 appended:
- La fïgur-e 1 illustre schématiquement ce dispositif ;- Figure 1 illustrates schematically this device;
- La figure 2 est un schéma explicatif de l'opération d'épluchage proprement dit réalisée sur une pomme de terre- Figure 2 is an explanatory diagram of the actual peeling operation performed on a potato
- Et la figure 3 est une illustration schématique d'un apparei avec système d'alimentation en continu de produits à épluc- And Figure 3 is a schematic illustration of an apparatus with continuous feed system for peel products
Conformément à l'invention, les produits à éplucher sont rendus solidaires d'un système qui leur fait subir, dans un milieu aqueux ou aérien, un mouvement (1) réglé de translation, de rotation, et d'ascension par des moyensélectro-mécaniques qui fait défiler la totalité de la surface de l'élément à peler devant un élément de pelage dont la profondeur de pénétration est réglée par l'indicatio d'une sonde à ultra sons (2) dont la longueur d'onde sera adaptée aux dimensions de la machine et qui pourrait se situ entre 2 et 7 MégaHertz. La sonde donne une mesure de distanc (3) par rapport à la peau de l'élément à peler ; à cette mesure, correspond un niveau électrique qui, par l'intermé¬ diaire d'un amplificateur différentiel (4) va agir par un moyen électromécanique ou hydraulique (5) faisant plus ou moins avancer l'élément de pelage (6). Un étalonnage et un réglage simple par rapport à un zéro virtuel de mesure de la sonde permettra de peler une épaisseur plus ou moins grande de peau.According to the invention, the products to be peeled are made integral with a system which makes them undergo, in an aqueous or aerial medium, a movement (1) regulated in translation, rotation, and ascent by electro-mechanical means. which scrolls the entire surface of the element to be peeled in front of a peeling element whose penetration depth is adjusted by the indication of an ultrasonic probe (2) whose wavelength will be adapted to the dimensions of the machine and which could be between 2 and 7 MegaHertz. The probe gives a measurement of distance (3) from the skin of the element to be peeled; this measurement corresponds to an electrical level which, by means of a differential amplifier (4) will act by electromechanical or hydraulic means (5) causing the peeling element (6) to move more or less. Calibration and simple adjustment relative to a virtual zero measurement of the probe will peel a greater or lesser thickness of skin.
Selon la vitesse de rotation du fruit ou du légume à peler, la sonde pourra être déplacée sur un arc de cercle plus ou moins grand afin que l'élément de pelage reçoive une information qui corresponde à la distance effective entre le zéro virtuel de l'élément de pelage et la zone de peau du fruit ou du légume à peler. Plusieurs couples éléments de pelage, sondes à ultra sons peuvent permettre un pelage plus rapide.Depending on the speed of rotation of the fruit or vegetable to be peeled, the probe can be moved over a more or less large arc so that the peeling element receives information which corresponds to the effective distance between the virtual zero of the peeling element and the skin area of the fruit or vegetable to be peeled. Several pairs of peeling elements, ultrasonic probes can allow faster peeling.
L'élément de pelage pourrait être une fraise ou selon une variante, une gouge, un racloir, un jet puissantThe peeling element could be a strawberry or, alternatively, a gouge, a scraper, a strong jet.
L'eau dans laquelle s'effectue le pelage est brassée par une hélice qui produit un courant débarrassant la zone de mesure et de pelage des multiples débris de peau, un système simple de filtres permettant de les éliminer.The water in which the peeling takes place is stirred by a propeller which produces a current ridding the measurement and peeling area of the multiple skin debris, a simple system of filters allowing to eliminate them.
Selon une variante, pour l'appareil industriel est prévu un système d'alimentation en continu des fruits et légumes pour arriver devant l'élément de pelage. Pour l'appareil domestique, un circuit circulaire (A) permettra de peler une douzaine de fruits ou de légumes. According to a variant, for the industrial apparatus there is provided a system for continuously supplying fruit and vegetables to reach the peeling element. For the domestic appliance, a circular circuit (A) will peel a dozen fruits or vegetables.
