FR2540346A1 - Device for recovering flesh from a pre-cooked carcass - Google Patents

Abstract

The invention relates to a device making it possible to recover flesh from small carcasses which are pre-cooked in advance by means of a dry vapour oven. It consists of a dispenser 1 under which a conveyor 2 conveys the pieces of carcasses towards a conveyor 3 doubled by a conveyor 4. The pieces of carcasses are pinched between the two conveyors and entrained towards a double series of comb rollers 5 and 6 which, rotating on their axes, brush the pieces of carcasses and detach the meat which is sucked into a container 7 placed under the conveyors. The bones from the carcasses are recovered in a separate container 10. This device is driven by an incorporated hydraulic unit 11. It operates continuously or by means of manual intervention.

Description

Recovery of flesh from pre-cooked carcass.

The present invention relates to materials of the meat separator type intended for human consumption.

In known materials, two systems are applied.

The first separates the muscles of the bones by compression, the product obtained is a paste called surfine, for very specific use.

The second assigned to the recovery of pork for the preparation of rillettes works on the principle of a poultry plucker.

The two techniques do not allow pieces of meat to be recovered from small carcasses or small pieces of carcass - whose too fragile bones are either crushed or broken and adhere to the flesh.

The present invention shown in Figure 1 eliminating these drawbacks allows the recovery of flesh on small carcasses or pieces of carcasses; rabbits, sheep, goats, poultry, game birds and fur.

Beforehand, the carcasses are pre-cooked by dry steam oven (1200), the only cooking method maintaining the firmness of the meats and retaining all the organoleptic qualities, then stored in a dispenser-dispenser (1) under which a conveyor (2) conveys the carcasses to a second mesh conveyor (3). This conveyor is doubled by an upper conveyor (4) which clamps, without tightening, the piece of carcass.

The spacing between the two conveyors is adjustable to allow the passage of pieces of carcasses of different volumes.

Pinched between these two mesh conveyors, the carcass piece is driven towards a double series of comb rollers (5) and (6).

The upper series (5) is offset from the lower series (6).

The direction of rotation of the comb rollers (5) is reversed with respect to the direction of rotation of the series comb rollers (6).

The last comb roller of the upper series (5) rotates in the same direction as the comb rollers of the lower series (6), the last comb roller of the lower series (6) rotates in the same direction as the rollers - combs of the upper series (5).

The carcass pieces, held between the two conveyors (3) and (4), are brushed by the combs of the rollers rotating on their axis at variable speed. The comb rollers move laterally on their axis, causing a double brushing movement.

Figure 2, the teeth of the combs (1) pass through the meshes (2) of the conveyors.

 .the conveyors move at slow speed. This speed is variable, adaptable to the desired flow rate and according to the conformation of the pieces of carcass lésésitant brushing more or less long.

 brushed meat is sucked into a container (7) placed under the conveyor (3).

 7th bin is mobile, independent of the whole. After passing between the series of comb rollers, the conveyors (3) and (4) move apart.

A fixed comb (8) causes the pieces of carcass possibly retained to fall between the meshes of the conveyor (4). The conveyor (3) is freed from pieces of carcass which it drives to the receiving tank (10) by a fixed comb (9). The entire device is driven by an incorporated hydraulic unit (11).

 The equipment operates in continuous automatic mode or in operation by manual intervention.

Claims (8)

 1- Process for recovering meat from small cocasses. Characterized in that the carcasses are pre-cooked in a dry steam oven, then stored in a metering device (Ij under which a conveyor (2) routes the carcasses to a second mesh conveyor (3). This conveyor is doubled by a parallel conveyor (4) which clamps - without tightening - the piece of carcass. Held between the two conveyors, the carcass is driven towards a tunnel in which there is a double series of comb rollers (5) and (6), the upper series (5) is offset from the lower series (6) and the direction of rotation of the comb rollers (5) is reversed with respect to the direction of rotation of the rollers of the series (6), the last roller of the upper series (5) rotating in the same direction as the comb rollers of the lower series (6). The last comb roller of the lower series (6) rotating in the same direction as the comb rollers of the upper series (5). The carcass pieces are brushed by the combs of the rollers rotating on their axis.  2- Apparatus for the development of the process according to claim (1) characterized in that the meat recovery means consists of a double mesh conveyor (3) and (4) driving them by maintaining them carcasses to a double series of comb rollers (5) and (6).  3- apparatus for recovering flesh from small carcasses according to claim (2) characterized in that the series of comb rollers (5) and (6) brush the carcasses through the meshes of the conveyors (3) and (4) by turning on their axis while moving laterally on this axis.  4- apparatus for recovering flesh from small carcasses according to claims (1) and (3) characterized in that the teeth of the combs of the rollers (5) and (6) lift the flesh from the carcasses by rotary and lateral brushing .  5- apparatus for recovering flesh from small carcasses according to claims (3) and (4) characterized in that the combs of the rollers are of variable rigidity.  6- apparatus for recovering flesh from small carcasses according to claims (2-3-4) characterized in that the meat detached from the bones by brushing the comb rollers is sucked into a mobile container (7) located under the series rollers (5) and (6).  7- apparatus for recovering flesh from small carcasses according to all of the preceding claims, characterized in that the parallel conveyor (3) and (4) releases the bones from the carcass after combing these carcasses by the double series of rollers combs moving away and allowing the recovery of the bones in a tank (10) independent of the device.  8- Apparatus for recovering flesh from small carcasses according to all of the preceding claims, characterized by continuous automatic operation or operation by manual intervention.
