Abstract

Cutting machine, particularly for cutting blocks of meat, comprising a disc-shaped cutting blade 3 rotationally driven about its axis and means for moving the surface to be cut of at least one block of meat translationally over the surface of a support plate 2a located parallel to the blade at a small adjustable distance from the latter, so as to make the cutting edge of the blade penetrate the said block, characterised in that the said translation takes place along a circular path which is a secant with respect to the disc.

Description

SLICING MACHINE IN PARTICULAR FOR LAMINATING THE
MEAT.

The subject of the invention is a machine intended in particular, but not exclusively, for the manufacture of puff meat, that is to say divided into ultra-thin slices which will then be optionally reconstituted into roasts, cutlets, steaks or the like by shaping with a binder.

French patent application No 86 02793, filed by
Applicant on February 28, 1986 for: "Method for manufacturing roasts, cutlets, steaks or the like by shaping ultrafine meat sheets with a binder", describes a lamination process which involves kneading thick pieces of meat relatively weak, with injection of carbon dioxide snow or other refrigerant and, after stabilization of the temperature of the mixture obtained below OOC, its shaping with a binder to form blocks easy to cut into sheets.

These blocks, advantageously cylindrical, have sufficient resistance to cold (for example between -50C and 100C) to allow them to be sliced into ultra-thin sheets, that is to say having thicknesses between a few tenths of mm and 1 mm for example.

The invention makes it possible to produce a simultaneous high-speed slicing machine, in ultra-thin slices, of a plurality of blocks of meat of prismatic or, preferably, cylindrical shape.

The machine according to the invention comprises a cutting blade in the form of a disc driven in rotation about its axis and means for moving the surface to be cut by at least one block of meat in translation on the surface of a plate. support disposed parallel to the blade at a small adjustable distance from the latter, so as to cause said block to penetrate by the cutting edge of the blade and is characterized in that said translation takes place along a circular path intersecting with respect to the disc.

According to a preferred embodiment, a barrel defining at least one housing serving as a receptacle for a block of meat is rotatably mounted about an axis parallel to that of the disc.

According to a particular feature, the support plate has a portion of contour in an arc of a circle parallel to the circular cutting edge of the blade and at a short distance therefrom, so as to ensure the continuity of the support of the block which gradually leaves the support plate to rest on the blade.

Other features, as well as the advantages of the invention, will become apparent in the light of the description below.

In the attached drawing:
Figure 1 is a partial view of a
browse in accordance with a preferred embodiment of
the invention, in section along II of FIG. 2
Figure 2 is a schematic plan view and
partial of this machine.

We see in the drawing that the machine essentially comprises barrels la-lb-lc each associated with a support table 2a-2b-2c, a cutting disc 3 and a support table 4. The tables and the blade are horizontal in the preferred embodiment described, so that the blocks of meat descend vertically during slicing, in the cylindrical support and guide housings, such as 10a, which the barrels define, and the slices fall into a tray 5 placed on table 4 or on a horizontal conveyor belt.

There have been shown, by way of example, three barrels each comprising eight housings, making it possible to cut twenty-four slices by complete pass.

The disc 3 is rotated at high speed by a motor 30 around a fixed vertical axis 31, by means of a transmission 32.

Each barrel, such as the, is rotatably mounted about an axis which pivots in a bracket lla and driven at a lower speed than the disc and advantageously in the same direction by a motor 12a via a transmission 13a.

Each support table, such as 2a, is mounted at an adjustable height on the support table 4 by means of rigid columns such as 20a-20b on which sleeves slide, such as 21a.

It can be seen in FIG. 2 that the portion 22a of the contour of the support tables closest to the disc 3 is shaped in a parallel arc. to the cutting edge at a very short distance from it. The position of the upper plane of the support tables is adjusted at a distance from the lower plane of the disc equal to the desired slicing thickness.

The different support tables can be adjusted to different heights to obtain, for example, a first thickness of sheets, for example 0.3 mm, and a second thickness, for example, 1 mm: for white meats, the Applicant has found that the alternation of thicker leaves and thinner leaves in the reconstituted roast improves its resistance.

Cylindrical blocks of leafing meat having been introduced into the barrel housings, there is introduced into the central cylindrical chamber 14a of the barrel around which the housings are distributed, a pressing mass 15a to which a cover 16a which is pressed is attached. the top of the meat blocks.

A pressing force is thus exerted on the blocks of meat, perpendicular to the planes, offset in height, of the blade and of the support table, each block passing, without ceasing to be kept in support, from the table d support on the upper surface of the disc.

Certain blocks having, at a given instant in the operation of the machine, undergone more slicing than the others, will lose, as soon as they leave the disc, contact with the cover by falling on the support table of the very weak height which corresponds to the thickness of a slice, and they will not find the support of a cover until after all the others have in their turn undergone the last slicing.

The cut slices, located below the disc, fall into tray 5.

Claims  1. Slicing machine, in particular blocks of meat, comprising a disc-shaped cutting blade (3) driven in rotation about its axis and means for moving the surface to be cut by at least one block of meat in translation on the surface of a support plate (2a) disposed parallel to the blade at a small adjustable distance from the latter, so as to make said block penetrate by the edge of the blade, characterized in that said translation s' performs along a circular path intersecting with respect to the disc.  2. Slicing machine according to claim 1, characterized by at least one barrel (la) defining at least one housing (10a) serving as a receptacle for a block of meat, rotatably mounted about an axis parallel to that of the disc.  3. Machine according to claim 1 or 2, characterized in that the support plate (2a) has a portion of contour in an arc of a circle parallel to the circular cutting edge of the blade and at a short distance from it, so as to ensure the continuity of the support of the block which gradually leaves the support plate to take support on the blade.  4. Machine according to claim 2, characterized by a plurality of barrels (la-lb-lc) each provided with a plurality of housings distributed around a central chamber (14a) in which engages a mass (15a) of pressing of the blocks, of which a cover (16a) is integral which comes to press on the upper part of the blocks, said barrels being distributed around the disc (3).  5. Machine according to claim 4, characterized in that the support plates (2a-2b-2c) which cooperate with said barrels (la-lb-lc) are located in planes parallel to that of the disc and at distances adjustable independently of each other.
