Abstract

Tubular skewer for skewer device intended for preparing meat brochettes (kebabs) and/or other food products such as vegetables, fruit or fish, in particular for skewer device of the type comprising a skewing cluster consisting of a plurality of tubular skewers 1, which are mobile axially and whose upper part is capable of receiving a small stick or spike, the said skewers being mounted so as to be slidable into a reception platform provided with holes allowing their passage and the skewing of slices or layers of meat or other product resting on the said platform, characterised in that the said skewer 1 is provided, externally, with sharp longitudinal ribs 1a forming blades. The invention also relates to the skewer device comprising a skewing cluster consisting of a plurality of skewers having the abovementioned characteristics.

Description

Tubular spit for skewer intended for the preparation of skewers of meat and 1or other food products.

The present invention relates to a tubular spindle for skewer or machine intended for the automatic skewering of slices or layers of meat and / or other food products such as fish * vegetables or various fruits, for the preparation of skewers of these products ready for cooking.

Advantageously, the invention relates to a tubular spindle intended to equip a skewer CFR-A-2 515 023) comprising a racking beam formed by a plurality of axially movable tubular spindles, the upper portion of which is capable of receiving a small stick or spike, said tubular pins being mounted with an axial sliding ability, in a receiving plate provided with holes allowing their passage and skewering of slices or layers of meat or other product resting on said plate. In addition, the latter is preferably constituted by the lower guide plate, of a skewer or cutting basket or basket whose side walls are, in known manner, provided with vertical slots for the passage of a or several sharp blades. A skewer of this kind allows automatic and rapid skewering of the stacks of slices of meat and / or vegetables, fruit or fish, intended for the preparation of skewers of these products whose preparation time is thus considerably reduced. .

When using this machine, it has been found that skewering the superimposed layers of meat required, in certain cases, a significant effort arising from the fact that the resistance to perforation of the latter by the tapered ends of the spikes and tubular pins is relatively large, while said plugged layers then do not slide easily over said tubular pins? because of the high number of these. Although these tubular pins are made of good quality stainless steel? it was found that the significant effort necessary for skewering the layers of meat could cause buckling of said tubular pins which it is then essential to replace.

The object of the present invention is to remedy this drawback.

According to the invention, this object is achieved thanks to a new embodiment of the tubular pins of the skewer according to which the latter are provided, externally, with sharp longitudinal ribs forming as many knives.

These sharp ribs or knives promote the penetration of the tubular pins into the superimposed slices or layers of meat or other food product and the sliding thereof on said tubular pins, during the skewering operation. As a result, these cutting ribs suppress the bending or buckling of said pins during this operation.

The invention also relates to skewers fitted with tubular skewering pins comprising the above characteristic.

The objects, characteristics and advantages mentioned above and others still will emerge more clearly from the description which follows and from the appended drawings in which:
Figure 1 is an elevational view with partial axial section of a tubular skewer spindle according to the invention.

Figure 2 is an enlarged view in section along line 2 - 2 of Figure 1.

Figure 3 is, on a larger scale, a view of the tapered end of this pin.

Figure 4 is a partial view of an automatic skewer equi-pe of tubular skewering pins according to the invention and shown in a position corresponding to an intermediate step of a skewering operation of a stack of wafers a food product.

Reference is made to said drawings to describe an interesting embodiment example, although in no way limiting, of the tubular pins and of the skewer according to the invention.

In the present description, it is AGREED for the sake of clarity, that the term "skewer" designates the finished article, for the preparation of which are intended the tubular pins and the skewer according to the inventton, this article being constituted by small skewered pieces of meat and / or vegetables, fruit, or fish, while the word "spade indicates the small spit or stick on which the said pieces are skewered at the end of the skewering operation.

The spindle 1 provided with the improvement according to the invention is, more particularly advantageously, intended to equip a skewer of the kind which is illustrated in the document FR-A 2 515 023 and comprising a skewering bundle constituted by a plurality of vertical tubular pins movable axially and whose upper portion is intended to receive a spike 2. These tubular pins which are, for example, fixed by their lower end, on a horizontal plate 3 vertically movable are also mounted with a suitability sliding, in a receiving plate 4 provided with holes with a vertical axis allowing their passage. According to the mode of use ~ tion illustrated in Figure 4, the pins 1 are, on the other hand, mounted with a sliding latitude on vertical rods 5 constructing the means for supporting and ejecting said spikes.

The receiving plate 4 is advantageously constituted by the lower guide plate of a skewering and cutting basket of which only the perforated bottom 6 is shown in FIG. 4, The receiving plate is, according to the exemplary embodiment filustrine, movable in vertical translation and supported by a plurality of mentally vertical drive cannons 7, axially movable and arranged, coaxially, around the tubular pins mounted with sliding ability in said drive cannons.

A skewer of this kind works in the following way: the slices of meat and / or other food product T, T ', T' ', etc., are successively arranged one above the other on the movable plate 4 and pressed downwards, which brings about the descent of said tray and of the canons which slide on the tubular skewering pins 1. During this downward movement, the slices T, T ', T' 'stacked on the tray are skewered on the tubular pins 1 which are immobilized. When the skewer basket is full, the tubular pins 1 are moved down and removed from the stack of slices which remain skewered by the spikes 2 previously housed in said pins and which are held in the skewering position by the rods 5 support and ejection of said spikes.

According to the invention, each tubular skewering spindle 1 comprises, externally, sharp longitudinal ribs 1a, forming as many knives. These cutting ribs are preferably equidistant. Each spindle is, for example, provided with four ribs 1a, the cutting edges of which are also spaced 900 apart.

Each cutting rib la has, advantageously, a triangular section or profile and its faces la 'form, between them, an angle which is, for example, of the order of 45.

The longitudinal ribs la extend from the upper end taper lob of the pins to the lower cylindrical end portion lc of the latter serving for their attachment to the movable horizontal plate 3. In their upper end portion the ", the the cutting ribs therefore have a height decreasing directly from the upper end of the spindle.
