Definitions

  • the invention which relates to a device for treating products under controlled atmosphere and temperature, in particular food products, relates more precisely to the inerting of the zone of production of said products as well as the particular means associated with it for the introduction of the product into the area and its extraction.
  • metabisulfite When metabisulfite is used in massive doses, it whitens the potato which is impregnated with it and which can then absorb oxygen which can eventually migrate through the wall of its packaging, which allows the use of a permeable packaging bag. oxygen, therefore thinner and less expensive.
  • metabisulfite treatment has the drawback of making the potato spongy when it comes to cooking, but also of releasing enzymes which affect the taste quality of the product consumed.
  • One of the merits of the invention lies precisely in that it makes it possible to very significantly limit the quantity of metabisulfite used before the treatment and packaging of the food product by the fact that it proposes to ensure the inerting of any the product development zone, zone towards which, in which and leaving from which the product is treated continuously to obtain a final product, which does not have the drawbacks mentioned above.
  • the device according to Swiss patent CH-A-331 721 relates to the processing and packaging of coffee under an inert atmosphere in several successive boxes. No temperature control is planned.
  • the device of the invention differs from this patent in that it treats non-fluid products, under controlled temperature and in a single box whose introduction lock forms a washing mechanism.
  • German patent DE-C-522,736 it allows the packaging under an inert atmosphere of solid or liquid products in a box having an introductory airlock forming a mechanism for washing the packaging containers arranged on a conveyor belt.
  • the device according to this German patent does not, however, provide for treatment or washing of the product to be packaged and does not include a temperature control.
  • the object of the present invention therefore consists of a device for treating non-fluid products under an inert atmosphere and controlled temperature, in particular food products such as potatoes, comprising a plurality of mechanisms capable of ensuring continuous washing, mechanical treatment and packaging of the treated product, in which the inerting takes place in an interior chamber of a single sealed box having an airlock formed by the washing mechanism and an airlock for extracting the box , the box containing at least the mechanisms capable of providing mechanical treatment.
  • a sealed box delimits a chamber filled with an inert atmosphere with low overpressure inside which there is a succession of treatment and transfer stations, the box being provided with an airlock. introduction and an airlock.
  • the introductory airlock is an immersion airlock consisting of a tank filled with a rinsing liquid, placed both outside and inside the box, which it through an opening provided in one of the walls, said wall at the edge of this opening plunging into the liquid and forming a barrier between the outside air and the inerted chamber.
  • a bagging machine of a type known per se, is associated with a hopper tightly connected to one of the last transfer devices provided in the production zone, and constitutes an airlock. extraction of the product outside the production area.
  • a zone 1 for developing the product essentially comprises a sealed box 2 of parallelepiped shape which rests on supports 3.
  • One end of the box, at its lower part, has an opening 4 in one of its side walls. This opening made it possible to position on the bottom of the box and inside thereof a tank 5 filled with a rinsing liquid 6.
  • the level of the liquid is such that the upper edge of the opening 4 on the wall side of the box, plunges into the liquid which then forms a barrier between the outside air, and the chamber 7, inside the box.
  • the bottom of the tank 5 has a pit 9 which serves as a housing for the lower end of a continuous belt elevator 10 returning to a lower drum 11 embedded in the liquid 6 and an upper drum 12 located inside and at the top of the box 2 and driven by an external motor 15.
  • the strip 10 carries buckets or pallets 13 which can extract the potatoes which have been poured into the tank 5 outside the box, as shown by the arrow in FIG. 1 and which, washed by the liquid 6, will be oriented by the guide plate 13 ′ towards the pit 9 to be taken up by said belt elevator 10.
  • To this latter is associated a fixed lower plate 17 for collecting the rinsing liquid and returning it to the tank 5.
  • a drip conveyor 14 also consisting of an endless belt with continuous unwinding 16 which is obviously formed of flexible meshes allowing the flow of the rinsing liquid, as can be seen more precisely in FIG. 2.
  • This liquid is advantageously recycled to the rinsing bath 6.
  • the drip conveyor 14 pours the drained potatoes into an inlet chute 18 to a cutting machine 19.
  • the band 21 develops upwards inside a waterproof cover 27 which communicates with the box 2.
  • the strip 21 is driven by a motor 28 external to the box 2 (FIG. 2).
  • the cut potatoes are, during their movement on the strip 21 subjected to a new rinsing by a spraying device 22 which projects a mixture of water and metabisulfite, or any other antioxidant product, all skilfully dosed. Potatoes thus cut and treated are discharged at the top of the lifting strip 21 and poured into a hopper 23 which is tightly connected to the cover 27 just below the upper end of the strip 21. This hopper orients the cut potatoes towards a tube 24 at the bottom of which they are collected in a packaging bag 25.
  • a bagging machine 26 of a type known per se which also acts as an airlock because the plastic film constituting the packaging bag, reconstitutes, after sealing, and by its shape, a supply tube identical to the tube 24 and a minimal laminar slot between the tube and the outside is created.
  • an inert atmosphere for example nitrogen
  • This relative overpressure is established in the tube 24 and prevents air ambient to enter the sachet subjected to the same nitrogen pressure, the end of the sachet having been previously sealed.
  • This extraction station which constitutes a final airlock also has the objective of keeping the product isolated during its transfer from the manufacturing enclosure to its packaging bag, before it is sealed at its upper part by the machine 26.
  • the treatment of the product in question is carried out continuously inside an enclosure inerted 7.
  • the inerting of the box for example as was said by virtue of a nitrogen atmosphere with low overpressure, is conventionally provided by a source of inerting using inlet and outlet pipes. flow of fluids provided with suitable valves, not shown.
  • maintaining the inert atmosphere of chamber 7 at a rigorously controlled predetermined temperature is ensured by conventional means not described or shown.
  • a certain number of mechanisms are also provided outside of the sealed box 2.
  • the drive motors 15 and 28 which have been mentioned previously, but also the motor mechanism 29 of the cutting machine 19 and its discharge belt 20, as well as the mechanism 30 associated with the operation of the bagging machine 26.
  • the movement transmission members and the various conduits which must connect the mechanism 29 and the machine 19 of course passing through the box 2 in a sealed manner.
  • the invention has been described on a preferred embodiment for the treatment of potatoes with a view to their freezing or refrigeration and their packaging. It goes without saying that the invention is not limited to this particular application, but also finds use for other products in the food sector and in particular for the treatment of food emulsions.
  • the product could be introduced into the inerted preparation zone using an entry airlock which would, for example, be placed upstream of a grinder.
  • An entry airlock for empty packaging as well as an exit airlock for filled packaging, that is to say pots or containers containing the product, would then be provided at the entry and exit from the zone d 'development which would contain, in addition to the crusher, the appropriate packaging machine.
  • the invention would also find use in fields other than the food industry, such as the chemical industry, pharmacy, cosmetology and for all applications which require continuous product treatment in an inert atmosphere, with airlock. 'entry and exit.
