Abstract

This method is characterised in that the piece of meat MC only partially occupies the volume of the bag S, in that the exudates EX are collected in the free part S2 of the said bag, in that an insulating operation is performed by leaktight welding SD and this part S2 is then separated from the rest of the bag containing the piece of meat, downstream of SD.

Description

L'invention se rapporte à un procédé d'étuvage et/ou de cuisson d'une masse carnée (jambon ou viandes salees par exemple) enfermée à itintérieur d'un sac etanche qui suit cette masse jusqu'à la commercialisation de celle-ci. The invention relates to a method of steaming and / or cooking a meat mass (ham or dirty meat for example) enclosed inside a waterproof bag which follows this mass until it is marketed. .

De cette manière, le produit emballé dans ce sac étanc-he n'est jamais en contact avec l'air libre après l'opération préservatrice que constitue 1 'étuvage ou la cuisson. In this way, the product packed in this waterproof bag is never in contact with the open air after the preserving operation which constitutes steaming or cooking.

On a neanmoins constaté que cette operation provoquait l'apparition d'exsudats formés de jus, de graisse, etc... qui après refroidissement, soit restent sous-forme liquide, soit constituent une gelée et parfois les deux ; leur presence dans l'emballage parait souvent suspecte à l'acheteur. It has nevertheless been observed that this operation causes the appearance of exudates formed from juice, fat, etc. which after cooling either remain in liquid form or constitute a jelly and sometimes both; their presence in the packaging often seems suspicious to the buyer.

I1 y a donc le plus grand intérêt à éliminer ces exsudats ou tout au moins à en diminuer l'importance. There is therefore the greatest interest in eliminating these exudates or at least reducing their importance.

L'invention vise donc un procédé tendant à cette fin. The invention therefore relates to a process tending to this end.

Ce procéde se particularise en ce que la masse carnée n'occupe que partiellement le volume du sac, que l'on recueille les exsudats dans la partie libre du dit sac, que l'on isole par soudure étanche et sépare ensuite cette partie du reste du sac contenant la masse carnée. This process is particular in that the meat mass occupies only partially the volume of the bag, that the exudates are collected in the free part of the said bag, which is isolated by sealed welding and then separates this part from the rest of the bag containing the meat mass.

D'autres particularites et avantages apparaitront à la lecture de la description et des revendications qui suivent, faites en regard des dessins sur lesquels
- la figure 1 est une vue en perspective d'une masse carnée au début de l'opération d'étuvage et/ou de cuisson ;
- la figure 2 montre le sac, exsudat recueilli
- la figure 3 est une vue identique apres soudure de la poche contenant l'exsudat.Other features and advantages will appear on reading the description and the claims which follow, made with reference to the drawings on which
- Figure 1 is a perspective view of a meat mass at the start of the steaming and / or cooking operation;
- Figure 2 shows the bag, exudate collected
- Figure 3 is an identical view after welding of the pocket containing the exudate.

Comme on le voit sur ces figures, on place la masse carnée MC dans un sac S en matière plastique thermosoudable d'un volume substantiellement supérieur à celui de la dite masse, on ferme le dit sac S d'une manière étanche, selon un moyen connu, on place la masse MC dans la partie S1 du sac
S de maniere à laisser libre une partie S2 de celui-ci afin d'y recueillir l'exsudat EX (jus et gelée) pendant ou après 1 'étuvage ou la cuisson, puis on isole par soudure étanche
SD cette partie S2 de celle S1 du sac S contenant la masse carnée, on sépare ces parties S1 et S2en- aval de s . As can be seen in these figures, the meat mass MC is placed in a heat-sealable plastic bag S of a volume substantially greater than that of the said mass, the said bag S is closed in a sealed manner, according to a means known, we place the mass MC in part S1 of the bag
S so as to leave a free part S2 of it in order to collect the exudate EX there (juice and jelly) during or after 1 steaming or cooking, then it is isolated by tight welding
SD this part S2 of that S1 of the bag S containing the meat mass, these parts S1 and S2 are separated downstream of s.

La concentration et la récupération des exsudats dans la partie S2 peuvent se faire tant que ceux-ci sont encore sous une forme liquide. Elles pourraient donc intervenir aussitôt après l'opération d'étuvage et/ou de cuisson. Concentration and recovery of exudates in part S2 can be done as long as they are still in liquid form. They could therefore intervene immediately after the steaming and / or cooking operation.

Si celle-ci s'effectue le sac S placé sur une grille
G (figure 1)1 il est facile de comprendre que les exsudats se concentreront dans les poches se produisant entre deux barreaux de la grille puis s'écouleront en direction de S2.If this is done the S bag placed on a grid
G (Figure 1) 1 it is easy to understand that the exudates will concentrate in the pockets occurring between two bars of the grid and then flow towards S2.

Evidemment, on peut faciliter ce transit en inclinant la surface d'appui, voire en plaçant sur la grille la masse
MC enfermée dans le sac S sur son extrémité voisine de la partie S2.Obviously, we can facilitate this transit by tilting the support surface, or even by placing the mass on the grid.
MC enclosed in the bag S on its end close to the part S2.

On peut imaginer pour faciliter la mise en oeuvre du procedé objet de l'invention, un sac comportant initialement deux enceintes communiquantes l'une pour la masse carnée, l'autre pour recueillir les exsudats. One can imagine to facilitate the implementation of the process object of the invention, a bag initially comprising two communicating enclosures one for the meat mass, the other to collect the exudates.

Le procédé objet des présentes est aussi utilisable dans le cas d'emploi d'un sac étanche dans lequel on a fait le vide. The process which is the subject of the present can also be used in the case of the use of a waterproof bag in which a vacuum has been created.

I1 est également -possible de produire un vide ou un nouveau vide après la récupération de la majeure partie des exsudats dans la poche S2 en pompant dans cette poche avant de pratiquer la soudure SD. Dans ce cas, la mise sous vide complète cette récupération. I1 is also -possible to produce a vacuum or a new vacuum after the recovery of the major part of the exudates in the pocket S2 by pumping in this pocket before practicing the welding SD. In this case, the vacuum completes this recovery.
