Definitions
- the present invention relates to a process for ultra-clean continuous transport of products from point P to point P 'inside a bacteriologically controlled area by means of a conveyor, as well as the installation necessary for the implementation of the process.
- the object of the present invention is therefore to propose an ultra clean transport method as well as the installation implementing this method, the installation and the method making it possible to transport products or containers from point P to point P ' using a sterile or almost sterile conveyor.
- the invention relates to a method of ultra-clean continuous transport of products and / or containers from point P to point P 'inside a bacteriologically controlled area by means of a conveyor. , characterized in that the receiving surface of the conveyor is continuously covered upstream of point P with a solid coating, the face intended to come into contact with the products and / or the containers is sterile or almost sterile, point P inside the bacteriologically controlled zone the products and / or containers to be transported on said coating and the products and / or containers transported are recovered at point P 'inside said zone.
- the coating of the receiving surface of the conveyor is eliminated, recovered or recycled downstream of point P ′, by mechanical, chemical, thermal or other means.
- This film-forming coating can be either a multilayer coating of which at least one of the interfaces between two any adjacent layer is sterile or almost sterile, a coating consisting of a sterilizable film-forming solution.
- the invention further relates to an ultrapropr installation characterized in that it comprises a conveyor for the transport of products or containers from a point P to a point P ', an area with controlled atmosphere on the bacteriological pla arranged at least on the portion PP ′, of means for depositing a sterile solid coating or quasi-sterile coating arranged upstream from point P, optionally means for recovering said coating arranged downstream from point P ′, and means for depositing and recovering products and / or containers to be transported on the coating.
- FIG. 1 represents a simplified diagram of an installation in accordance with the invention using a coating consisting of a sterilizable film-forming material or solution;
- FIG. 2 represents a simplified diagram of another installation in accordance with the invention, in which the coating is a multilayer film produced under sterile conditions or close to sterility.
- the implementation of the process requires having a conveyor such as a conveyor belt 1, preferably refrigerated, which passes through a zone 2 controlled bacteriologically.
- This zone can, for example, be constituted by an enclosure or a laminar flow tunnel.
- a portion PP ′ is defined, the point P corresponding to the location d depositing the product (or container) on the receiving surface of the conveyor, the point P 'corresponding to the recovery of said product from the receiving surface of the conveyor belt.
- These products can be of any type, including food and can be free or placed in containers.
- "Products" also means the containers themselves, empty or full.
- a point is designated by 3 in FIG. 1 which designates the starting point for laying the covering.
- This coating can, in accordance with FIG. 1, consist of a film-forming solution, prepared under sterile conditions or close to sterility which solidifies quickly and can, almost instantaneously from the moment it is deposited on the receiving surface. of the conveyor, harden so as to form a film.
- film-forming materials or solutions include ice, microcrystalline waxes, methylcellulose and its derivatives, food proteins, etc.
- To obtain the shaping of this solution in the form of a film it is possible to deposit the liquid solution on the conveyor belt just at the entrance to zone 2 with a bacteriologically controlled atmosphere and to pass said solution under a roller. so as to obtain a uniform solution thickness.
- the deposition can be carried out by means of a pump and a flat die.
- the coating When the coating has passed point P ′, it is generally recovered at a location designated by 9 in FIGS. 1 and 2.
- the means for removing and recovering said coating will be different.
- the film In the case of a sterilizable film-forming material or solution, the film is preferably recovered in accordance with FIG. 1 by peeling, scraping or simple separation of the surface receiving the products from the conveyor, then cut or ground in a designated device. by 8 in Figure 1 before being refluidized or melted in a tank designated by 7 in Figure 1, then filtered according to step 6 of Figure 1 before being sterilized, in accordance with step 5 of Figure 1, to again form a sterilizable film-forming solution which, in a subsequent step, will be redeposited on the receiving surface of the conveyor. In this case, it is possible to operate in a closed circuit and to deposit the coating continuously without the need to use a large amount of material.
- the coating is originally presented in the form of a solid coating such as a multilayer film, at least one of the interfaces between any two contiguous layers is sterile or almost sterile.
- a solid coating such as a multilayer film
- the layer placed above the sterile or almost sterile interface is eliminated and recovered on the reel 13, while the other layer remains in position on the surface for receiving the products from the conveyor and will be eliminated in 9 by taking up said film on a reel 12 which can in turn be conveyed to a structure of reprocessing to recover all of the material.
- Zone 2 aseptic or bacteriologically controlled may consist of an enclosure or a tunnel whose atmosphere is controlled or microfiltered.
- This type of enclosure or tunnel is perfectly known to those skilled in the art.
- the conveyor 1 it can be constituted by a conveyor belt as shown in Figures 1 and 2, refrigerated or not, or by any other means of continuous transport. Thanks to this process and to the installation implementing this process, any contamination during the transport of goods or products or their containers from point P to point P 'is avoided.
