Les sortes, structures et configurations du mécanisme de puissance et du mécanisme de réduction de vitesse peuvent être choisies et disposées de façon appropriée selon l'art antérieur dans ce domaine, et ne seront pas décrites ici en détail. As can be seen in FIG. 1, the rotary member 10 is provided at its center with a rotation shaft whose lower end is connected to a power mechanism and a speed reduction mechanism, so that the rotary member 10 can be rotated. The remainder of the rotary member at the periphery of the rotary shaft can be mounted on the rotation shaft and can thus rotate synchronously with the rotation shaft. Of course, the rotary shaft and the peripheral portion thereof may be provided integrally. The kinds, structures and configurations of the power mechanism and the speed reduction mechanism can be selected and appropriately arranged according to the prior art in this field, and will not be described here in detail.
Comme on peut le voir sur la figure 2, qui représente schématiquement la structure entière de l'organe rotatif 10, l'organe rotatif 10 comporte un corps principal 1 1 , qui est dans son ensemble d'une forme de fuseau plus petite en partie supérieure et plus grande en partie inférieure, et un corps hélicoïdal 12 situé sur la surface extérieure du corps principal 1 1 et présentant une distribution hélicoïdale le long de la surface extérieure du corps principal 1 1 de haut en bas. As can be seen in Figure 2, which schematically represents the entire structure of the rotary member 10, the rotary member 10 comprises a main body January 1, which is as a whole of a smaller spindle shape in the upper part and larger in the lower part, and a helical body 12 located on the outer surface of the main body 1 1 and having a helical distribution along the outer surface of the main body 1 1 from top to bottom.
Tel que représenté sur les figures 1 et 3, le corps tubulaire 20 est d'une forme tronconique plus grande en partie supérieure et plus petite en partie inférieure, c'est à dire, la partie supérieure de la paroi latérale du corps tubulaire 20 s'incline vers l'extérieur d'un certain angle par rapport à sa partie inférieure. L'orifice de décharge 30 est prévu dans une position proche du fond de la paroi latérale du corps tubulaire 20. Dans la périphérie dudit orifice de décharge peut être en outre prévue une butée, qui est structurellement solidaire du corps tubulaire ou qui est montée sur le corps tubulaire. Pour faciliter l'illustration de la relation de coopération entre l'organe rotatif 10 et le corps tubulaire 20, une partie de la paroi latérale du corps tubulaire 20 est enlevée sur la figure 4. Comme on peut le voir sur la figure 4, l'organe rotatif 10 est agencé dans le corps tubulaire 20, et un faible écart variable est prévu entre le corps hélicoïdal 12 et la surface intérieure de la paroi latérale du corps tubulaire 20. As shown in Figures 1 and 3, the tubular body 20 is of a frustoconical shape larger in the upper part and smaller in the lower part, that is to say, the upper part of the side wall of the tubular body 20 s inclines outward from a certain angle with respect to its lower part. The discharge port 30 is provided in a position close to the bottom of the side wall of the tubular body 20. In the periphery of said discharge port may be further provided a stop, which is structurally integral with the tubular body or which is mounted on the tubular body. To facilitate the illustration of the cooperative relationship between the rotary member 10 and the tubular body 20, part of the side wall of the tubular body 20 is removed in FIG. 4. As can be seen in FIG. rotary member 10 is arranged in the tubular body 20, and a small variable gap is provided between the helical body 12 and the inner surface of the side wall of the tubular body 20.
Tel que bien visible sur la figure 1 , l'organe rotatif 10 comporte de haut en bas une partie de coupe 13, une partie de collecte 14, une partie de poussée 15 et une partie d'extrusion 16. La partie de coupe 13 est principalement constituée par une partie du corps hélicoïdal 12 et est destinée à couper des matières premières en une forme plus petite. La partie de collecte 14 est constituée par une combinaison d'une partie du corps hélicoïdal 12 avec une partie du corps principal 1 1 et est destinée à collecter les matières premières coupées et tombant de la partie de coupe 13. La partie de poussée 15 est constituée par une combinaison d'une partie du corps hélicoïdal 12 avec une partie du corps principal 1 1 et est destinée à pousser les matières collectées dans la partie de collecte 14 vers la partie inférieure du corps tubulaire 20. La partie d'extrusion 16 est principalement constituée par une partie du corps hélicoïdal 12 et est destinée à coopérer avec la surface intérieure de la paroi latérale du corps tubulaire 20 de manière à extruder les matières en une fine crème glacée. Dans une quelconque section verticale de l'organe rotatif 10 le long d'un axe de rotation, la longueur radiale maximale de la partie de coupe 13 est supérieure à la longueur radiale maximale de la partie d'extrusion 16 de manière à correspondre à la paroi latérale inclinée du corps tubulaire 20, la longueur radiale minimale de la partie de collecte 14 est inférieure ou égale à la longueur radiale minimale de la partie de coupe 13 de manière à former une partie concave dans la direction radiale pour obtenir un plus grand espace dans la zone de collecte, la longueur radiale minimale de la partie de poussée 15 est supérieure ou égale à la longueur radiale maximale de la partie de collecte 14, et la longueur radiale maximale de la partie de poussée 15 est inférieure ou égale à la longueur radiale minimale de la partie d'extrusion 16, de manière à se rapprocher graduellement de haut en bas de la surface intérieure de la paroi latérale du corps tubulaire 20, pour faciliter la poussée progressive des matières premières coupées dans la partie d'extrusion 16. As clearly visible in FIG. 1, the rotary member 10 comprises, from top to bottom, a cutting portion 13, a collecting portion 14, a thrust portion 15 and an extrusion portion 16. The cutting portion 13 is mainly constituted by a portion of the helical body 12 and is intended to cut raw materials into a smaller form. The collection portion 14 is constituted by a combination of a portion of the helical body 12 with a portion of the main body 11 and is intended to collect the raw materials cut and falling from the cutting portion 13. The pushing portion 15 is formed by a combination of a portion of the helical body 12 with a portion of the main body January 1 and is intended to push the collected material in the part of 14 to the lower part of the tubular body 20. The extrusion portion 16 is mainly constituted by a portion of the helical body 12 and is intended to cooperate with the inner surface of the side wall of the tubular body 20 so as to extrude the materials in a thin ice cream. In any vertical section of the rotary member 10 along an axis of rotation, the maximum radial length of the cutting portion 13 is greater than the maximum radial length of the extrusion portion 16 so as to correspond to the inclined side wall of the tubular body 20, the minimum radial length of the collection portion 14 is less than or equal to the minimum radial length of the cutting portion 13 so as to form a concave portion in the radial direction to obtain a larger space in the collection zone, the minimum radial length of the thrust portion 15 is greater than or equal to the maximum radial length of the collecting portion 14, and the maximum radial length of the thrust portion 15 is less than or equal to the length radial axis of the extrusion part 16, so as to approach gradually from top to bottom of the inner surface of the side wall of the tubular body 20, for example the progressive push of raw materials cut in the extrusion part 16.
Comme on peut le voir sur les figures 1 et 3, sur la surface intérieure de la paroi latérale du corps tubulaire 20 est agencée une pluralité de nervures 21 , qui sont d'une forme allongée et sont destinées à renforcer l'effet de pression entre l'organe rotatif 10 et le corps tubulaire 20. La pluralité de nervures 21 peut être distribuée uniformément sur la surface intérieure du corps tubulaire 20. De préférence, la pluralité de nervures est agencée au moins sur une partie de la surface intérieure du corps tubulaire 20 correspondant à la partie d'extrusion 16, renforçant ainsi l'effet de pression entre l'organe rotatif 10 et le corps tubulaire 20 lors de la rotation de l'organe rotatif 10. As can be seen in Figures 1 and 3, on the inner surface of the side wall of the tubular body 20 is arranged a plurality of ribs 21, which are of elongate shape and are intended to enhance the pressure effect between the rotatable member 10 and the tubular body 20. The plurality of ribs 21 may be evenly distributed on the inner surface of the tubular body 20. Preferably, the plurality of ribs is arranged at least on a portion of the inner surface of the tubular body 20 corresponding to the extrusion part 16, thus reinforcing the pressure effect between the rotary member 10 and the tubular body 20 during the rotation of the rotary member 10.
Tel que bien visible sur la figure 1 , la partie inférieure du couvercle supérieur 40 recouvre une ouverture supérieure du corps tubulaire 20, et la partie supérieure du couvercle supérieur 40 présente un tube d'alimentation vertical.

As clearly visible in Figure 1, the lower portion of the top cover 40 covers an upper opening of the tubular body 20, and the upper portion of the top cover 40 has a vertical feed tube. The tray 50 is disposed above the top cover 40, and the tray 50 is provided with an outlet port communicating with an inlet port of the feed tube of the top cover 40.
Tel que bien visible sur la figure 1 , le couvercle supérieur 40 vient en prise avec le corps tubulaire 20. Le couvercle supérieur 40 comporte en effet des languettes d'accrochage inférieures venant en prise sous un rebord du corps tubulaire 20. Le couvercle supérieur 40 peut ainsi être verrouillé par baïonnette sur le corps tubulaire 20. As clearly visible in Figure 1, the upper cover 40 engages the tubular body 20. The upper cover 40 has indeed lower attachment tabs engaging under a rim of the tubular body 20. The upper cover 40 can thus be locked by bayonet on the tubular body 20.
La figure 5 montre un dispositif de préparation de crème glacée selon un deuxième exemple de réalisation de la présente invention, qui diffère du dispositif selon le premier exemple de réalisation en ce que le corps tubulaire 20 est placé dans un séparateur 60, en ce que la partie inférieure du couvercle supérieur 40 recouvre une ouverture supérieure du séparateur 60, et en ce qu'un orifice de décharge 61 du séparateur 60 communique avec l'orifice de décharge 30 du corps tubulaire 20. Ainsi, le corps principal dudit dispositif peut être agencé dans un séparateur d'un appareil existant pour améliorer la polyvalence dudit appareil. FIG. 5 shows an ice cream preparation device according to a second embodiment of the present invention, which differs from the device according to the first embodiment in that the tubular body 20 is placed in a separator 60, in that the lower part of the top cover 40 covers an upper opening of the separator 60, and in that a discharge port 61 of the separator 60 communicates with the discharge port 30 of the tubular body 20. Thus, the main body of said device can be arranged in a separator of an existing apparatus to improve the versatility of said apparatus.
Tel que bien visible sur la figure 5, le couvercle supérieur 40 vient en prise avec le séparateur 60. Le couvercle supérieur 40 comporte en effet des languettes d'accrochage inférieures venant en prise sous un rebord du séparateur 60. Le couvercle supérieur 40 peut ainsi être verrouillé par baïonnette sur le séparateur 60. As clearly visible in FIG. 5, the upper cover 40 engages with the separator 60. The upper cover 40 indeed has lower hooking tabs engaging under a rim of the separator 60. The upper cover 40 can thus be bayonet locked on separator 60.
Un procédé de préparation de crème glacée au moyen du dispositif selon la présente invention est comme suit. Tout d'abord, la congélation des matières premières est effectuée, les matières premières étant telles que des fruits, de la crème ou d'autres matières alimentaires avec un certain rapport de mélange, de préférence des fruits. La congélation peut être effectuée par exemple dans un compartiment de congélation d'un réfrigérateur, habituellement dans un environnement de congélation à -18 °C pendant au moins 4 heures. Ensuite, les matières premières congelées sont placées dans un dispositif de préparation de crème glacée. Par exemple, ce dispositif peut être un dispositif de préparation de crème glacée selon l'un quelconque des exemples de réalisation précédents de la présente invention. En ce cas, les matières premières congelées passent successivement à travers le plateau 50 et le tube d'alimentation du couvercle supérieur 40, et entrent dans le corps tubulaire 20 à partir de l'ouverture supérieure du corps tubulaire 20. A method of making ice cream using the device according to the present invention is as follows. First, the freezing of the raw materials is carried out, the raw materials being such as fruits, cream or other food materials with a certain mixing ratio, preferably fruits. Freezing can be carried out for example in a freezer compartment of a refrigerator, usually in a freezing environment at -18 ° C for at least 4 hours. Next, the frozen raw materials are placed in an ice cream maker. For example, this device may be an ice cream maker according to any of the previous embodiments of the present invention. In this case, the frozen raw materials pass successively through the tray 50 and the feed tube of the top cover 40, and enter the tubular body 20 from the upper opening of the tubular body 20.
Ensuite, les matières premières congelées sont coupées. Par exemple, la partie de coupe 13 de l'organe rotatif 10 peut être utilisée pour couper les matières premières congelées afin de former des formes plus petites. Then the frozen raw materials are cut. For example, the cutting portion 13 of the rotatable member 10 can be used to cut the frozen raw materials to form smaller shapes.
Puis, les matières coupées sont collectées et poussées vers le bas. Par exemple, la partie de collecte 14 de l'organe rotatif 10 peut être utilisée pour collecter les matières coupées. Avec l'accumulation continue des matières, la partie de poussée 15 pousse progressivement les matières vers la partie inférieure du corps tubulaire 20. Then, the cut materials are collected and pushed down. For example, the collection portion 14 of the rotatable member 10 may be used to collect the cut materials. With the continuous accumulation of materials, the pushing portion 15 progressively pushes the materials towards the lower part of the tubular body 20.
Enfin, les matières sont extrudées et finalement la crème glacée préparée est déchargée de l'orifice de décharge de la partie inférieure dudit dispositif. Par exemple, le petit écart entre la partie d'extrusion 16 de l'organe rotatif 10 et la surface intérieure (ou les nervures 21 ) de la paroi latérale du corps tubulaire 20 peut être utilisé pour extruder les matières sous forme d'une fine crème glacée, qui sont finalement déchargées à partir de l'orifice de décharge 30. De cette façon, les produits finis de crème glacée sont obtenus. Finally, the materials are extruded and finally the prepared ice cream is discharged from the discharge port of the lower part of said device. For example, the small gap between the extrusion portion 16 of the rotatable member 10 and the inner surface (or ribs 21) of the side wall of the tubular body 20 may be used to extrude the materials into a thin form. ice cream, which are finally discharged from the discharge port 30. In this way, the finished ice cream products are obtained.
En outre, l'orifice de décharge 30 peut se présenter sous différentes formes. Par exemple, la section d'extrusion de l'orifice peut prendre diverses formes (par exemple, circulaire, ovale, triangulaire, carrée et d'autres formes), de sorte que les produits finis de crème glacée des formes correspondantes peuvent être obtenus, améliorant ainsi le goût de dégustation. In addition, the discharge port 30 may be in different forms. For example, the extrusion section of the orifice can take various forms (for example, circular, oval, triangular, square and other shapes), so that the finished ice cream products of the corresponding shapes can be obtained, thus improving the taste of tasting.
Selon le dispositif et le procédé susmentionnés de la présente invention, les produits finis fins sous forme de crème glacée peuvent être obtenus en effectuant les étapes de coupe, de collecte, de poussée et d'extrusion des matières premières de manière séquentielle. L'existence des particules plus grandes et des résidus de glace dans la crème glacée peut être évitée et ainsi la sensation gustative de la crème glacée est améliorée. Le dispositif et le procédé de préparation de crème glacée de la présente invention sont décrits précédemment selon les exemples de réalisation, mais le dispositif et le procédé ne sont pas nullement limités aux pièces, aux relations de connexion et aux étapes décrites dans ces exemples de réalisation. Par exemple, la relation dimensionnelle entre la partie de coupe, la partie de collecte, la partie de poussée et la partie d'extrusion n'est nullement limitée aux exemples de réalisation représentés, à condition que les parties soient en mesure de remplir leurs fonctions respectivement. Les nervures peuvent être agencées sur toute la surface intérieure de la paroi latérale du corps tubulaire, peuvent être aussi agencées uniquement sur une partie de la surface intérieure correspondante à la partie d'extrusion. According to the above-mentioned apparatus and method of the present invention, the fine finished products in the form of ice cream can be obtained by performing the steps of cutting, collecting, pushing and extruding the raw materials sequentially. The existence of larger particles and ice residues in the ice cream can be avoided and thus the taste sensation of the ice cream is improved. The ice cream making device and method of the present invention are described above according to the exemplary embodiments, but the apparatus and method are not limited to the parts, connection relationships and steps described in these exemplary embodiments. . For example, the dimensional relationship between the cutting portion, the collection portion, the thrust portion and the extrusion portion is not limited to the exemplary embodiments shown, provided that the parts are able to perform their functions. respectively.
