EMBODIMENT OF THE INVENTION

[0055] FIGS. 1 and 3 show a stuffed past food item 1 comprising a wrap 2; and a stuffing dose 3 comprising at least one of the following base ingredients: meat, fish, vegetables, eggs, cheese, and mushrooms.

[0056] In particular, the food item 1 is ravioli (or the like).

[0057] In the case shown in FIG. 1, the food item 1 has an oblong shape and extends along a longitudinal axis Al.

[0058] Generally speaking, the wrap 2 comprises one or two sheets 4 and 5 obtained through rolling of a dough comprising flour, salt and a component containing water (for example, water and/or eggs).

[0059] According to some embodiments, each one of the sheets 4 and 5 has thickness up to approximately 2 mm (more precisely, up to approximately 1.4 mm; in particular, equal to at least 0.4 mm), more precisely, usually around 1 mm.

[0060] In particular, the wrap 2 is made of pastry, more in particular fresh pastry.

[0061] According to some embodiments, the food item 1 has a length of at least 4 cm, in particular of at least 7 cm, more in particular of at least 9 cm (more precisely, up to 20 cm). In addition or alternatively, the food item 1 has a width of at least 2 cm, in particular of at least 4 cm, more in particular of at least 7 cm (more precisely, up to 20 cm).

[0062] More precisely, each rib 10 has a width (crosswise to the fold) ranging from 0.5 mm to 4 mm. In addition or alternatively, each rib has a length (substantially parallel to the fold) ranging from 0.5 mm to 20 mm.

[0063] In the case shown herein, the wrap 2 comprises two sheets 4 and 5, which have respective flaps 6 and 7 facing one another and joined to one another; and respective central portions 8 and 9, which face one another and are spaced apart from one another so as to define a housing for the stuffing dose 3.

[0064] The composition of the sheets 4 and 5 (in particular, made of pastry; more in particular, made of fresh pastry) allows the flaps 6 and 7 to be caused to adhere to one another through gluing by applying a light pressure on the flaps 6 and 7.

[0065] In particular, the wrap 2 is made of pastry, more in particular fresh pastry.

[0066] According to some embodiments, the wrap 2 has a humidity content of at least 23% (in particular, at least 24%) by weight (relative to the total weight of the wrap). In particular, the wrap 2 has a humidity content up to 30% (more in particular, up to 27%) by weight (relative to the total weight of the wrap).

[0067] More precisely, the sheet 4 (and/or the sheet 5) has a humidity content of at least 23% (in particular, at least 24%) by weight (relative to the total weight of the sheet 4and/or of the sheet 5). In particular, the sheet 4 (and/or the sheet 5) has a humidity content up to 30% (more in particular, up to 27%) by weight (relative to the total weight of the sheet 4and/or of the sheet 5)

[0068] The expression stuffing dose 3 defines a discrete portion of stuffing comprising one or more of the aforesaid ingredients, which are cut into small pieces or chopped and mixed together. The stuffing dose 3 is characterized in that it has cohesion forces which allow the stuffing dose 3 to gain a shape that remains stable for an amount of time of some seconds.

[0069] According to some embodiments, the stuffing dose 3 has a weight of at least 3 grams (in particular, at least 10 grams). More in particular, the stuffing dose 3 has a weight up to 150 grams.

[0070] The wrap 2 comprises ribs 10, which fulfil the function of stiffening the wrap 2 in the area of the central portion 8, which is rounded unlike the central portion 9, which is flat and substantially defines a support surface of the food item 1.

[0071] According to a variant which is not shown herein, the central portion 9 (in addition to the central portion 8) is rounded and has ribs 10, as well.

[0072] The food item 1 has a greater stiffness along the joined flaps 6 and 7 because, along said flaps 6 and 7, it has a thickness that substantially is twice the thickness of the central portions 8 and 9.

[0073] The rounded central portion 8 substantially is deep-drawn and has a thickness that is slightly smaller than the initial thickness of the sheet 4 following a stretching of the sheet 4 itself.

[0074] Each rib 10 originates from the flaps 6 and 7, extends towards the centre of the food item 1 and consists of two wrap portions 11 of the central portion 8, which face one another, form a fold 12 between one another and form respective folds 13 with the remaining part of the central portion 8.

[0075] With reference to FIG. 1, the ribs 10 are distributed in a relatively uniform manner along the wrap 2.

[0076] FIG. 4 shows a shaping mould 14 to give the shape of the food item 1 of FIG. 1. The shaping mould 14 comprises a polymer material body having a face 15, where an opening 16 is obtained, which, in this case, is defined by a slit. Alternatively, the oblong opening 16 could be defined by a groove.

[0077] The face 15 has a protruding part 17, which is adjacent to the opening 16 (having the shape of the flaps 6 and 7 of the food item 1) and is configured to exert the pressure needed for the adhesion of the flaps 6 and 7. The oblong opening 16 is laterally delimited by inclined faces 18 and by cuts 19, which extend from the opening 16 to the inclined faces 18. The inclined faces 18 converge as the depth of the opening 16 (starting from the face 15) increases, whereas the depth of the cuts 19 decreases as the depth of the opening 16 (starting from the face 15) increases.

[0078] In use, the shaping mould 14 is used to shape the food item 1 by compressing the wrap 2 against a striker element or counter-mould, which, in this case, is simply defined by a flat or cylindrical surface, so as to cause the flaps 6 and 7 to adhere to one another, whereas the cuts 19 help shape and house the ribs 10. With reference to FIG. 1, the wrap 2 has a large content of water and, for this reason, has a very high plastic deformability; hence, the central portion 8 assumes the shape of the mould 14 along the walls 18 and the cuts 19 (FIG. 4).

[0079] FIG. 5 shows a cutting mould 20 to cut out the edge of the flaps 6 and 7. The cutting mould 20 comprises a polymer material body having a face 21 where an opening 22 is obtained, which is (internally) delimited by a side face 23, so as to house the rounded central part 8 of the food item 1 (FIG. 1), and has a thin wall 24 with a corrugated profile, which extends at right angles relative to the face 21 and is coplanar to the side face 23.

[0080] With reference to FIG. 6, number 25 indicates a production line to mass-produce food items 1.

[0081] The production line 25 comprises a dough station 26, where a dough is prepared and blended, said dough being used to obtain two continuous sheets F1 and F2 from which the sheets 4 and 5 are obtained. The continuous sheets F1 and F2 are sized in width and adjusted in thickness in a rolling station 27. In a feeding station 28, stuffing doses 3 are placed on the continuous sheet F2.

[0082] Alternatively, the stuffing doses 3 are inserted between the two continuous sheets F1 and F2 while they are being placed on top of one another.

[0083] Each stuffing dose 3 is enclosed between the two continuous sheets F1 and F2 in a shaping station 29, which comprises two rollers facing one another, wherein the upper roller is equipped with a plurality of moulds 14 (FIG. 4), each shaping, in contact with the lower roller, a respective food item 1 and compressing the flaps 6 and 7 of each food item 1 so as to cause the flaps 6, 7 to adhere.

[0084] Subsequently, the food items 1 are detached from the remaining part of the continuous sheets F1 and F2 in a cutting station 30, which comprises an upper roller equipped with a plurality of cutting moulds 20 (FIG. 5), each cutting the food items 1.

[0085] The food items 1 are subsequently fed through a pasteurization station 31, a dehumidification station 32 and a packing station 33 by means of a belt conveyor or other similar devices.

[0086] The transportation causes the food items 1 to be subjected to significant mechanical stresses, which substantially depend on the total weight thereof.

[0087] In the pasteurization station 31, the food items 1 are subjected to high-temperature steam, whereas, in the dehumidification station, the food items 1 are subjected to the removal of water, which can cause a different shrinking between the stuffing dose 3 and the wrap 2 (FIG. 1). In this specific case and with reference to FIG. 1, the ribs 10 prevent the central portion 8 from deforming due to the aforesaid stresses.

[0088] Indeed, despite the numerous stresses to which the food items 1 are subjected, the Applicant surprisingly found out that the food items 1 provided with ribs 10, even the large-sized ones, can stand the physical and mechanical stresses to which they are subjected over the course of the manufacturing process.

[0089] For example, experiments have shown that the food item 1 of FIG. 1 manufactured with relatively large sizes (with a total weight of 23.5 g, a length of 110 mm, a width of 40 mm, and a percentage by weight of the stuffing dose 3 exceeding 40%, in particular exceeding 50% relative to the total weight of the food item) has proved to have a good resistance to mechanical transportation stresses and a good stiffness of the rounded central portion 8.

[0090] The invention evidently includes further variants which are not explicitly described herein, though without going beyond the scope of protection set forth in the following claims.
