SI2995563T1 - Pneumatic apparatus for odorisation of a packaging, such as a food-preserving tray, containing a product, more particularly a food product, and corresponding method - Google Patents

Abstract

Apparatus (10) for odorising a packaging (CON), such as for example a food-preserving tray, wherein a product (PR), more particularly a food product, is packaged to be later consumed, wherein the apparatus (10) is suitable for producing and dispensing an odorising/aromatising substance (G1+G2+L, OD) in gaseous form in the packaging (CON) containing the product (PR), before the packaging is hermetically sealed and sent for consumption, and is characterised in that it comprises only mechanical parts and pneumatic devices (20, 30, 40) for producing, controlling and dispensing the odorising/aromatising substance (OD) in the packaging (CON) to be odorised, and therefore does not comprise electric and/or electronic devices which could be the source of risks for safety in the environment wherein this odorising apparatus (10) is installed. In addition to the advantage of not having electrical connections with the exterior and parts so as not to create safety problems, the odorising apparatus (10) of the invention also has that of having reduced dimensions and bulk so as to allow for example a wall attachment thereof and easy and problem-free integration in a packaging line.

Claims (10)

A pneumatic dispensing device such as, for example, a food preserving tray containing a product, more specifically a food product, and the associated process Patent claims A packaging device (10), for example, a food preserving tray in which the product is packaged and provided (PR), in particular a food product, wherein the device (10) is suitable for generating and transmitting the substance (G1 + G2 + L, OD) for gassing / flavoring in a gaseous form into a packaging (CON) that contains the product (PR) before the packaging is air-tightly closed, comprising: - a mixing system (20) for generating a gas mixture (G1 + G2) ; a oil mill or sprayer (30) for dispensing / flavoring the liquid (L) and mixing it with a gas mixture (G1 + G2) produced and supplied by the mixing system (20); and a container (40) where the mixture (G1 + G2 + L) of the dispersed liquid and gas is stored and where the molecular exchange occurs between this gas mixture supplied by the mixing system and the dispersed liquid, thus obtaining the substance (OD) for flavoring / flavoring for use in the odor of packaging (CON); characterized in that the device, including the mixing system (20), comprises only mechanical parts and pneumatic devices (20, 30, 40) which include pneumatic lines, various valves and similar devices for the production, control and emission of substances ( OD) for flavoring / flavoring in the package (CON), intended for odorisation, and therefore does not include electrical and / or electronic devices which could be a source of danger to safety in the environment in which the desalination device (10) is installed. A odor device (10) according to claim 1, characterized in that the oil mill or sprayer (30) is of such type that it comprises a Venturi hose for drawing (flavoring) aqueous liquid (L) and mixing it with a gas mixture ( G1 + G2) produced and supplied by the mixing system (20). A odor device (10) according to claim 2, characterized in that the oil mill is of such type that it is suitable for receiving a replaceable cartridge (CAR) containing a drier / flavoring liquid (L) for mixing with a gas mixture (G1 + G2) produced and supplied by the mixing system (20). The odor device (10) according to any one of the preceding claims, wherein the mixing system (20) is suitable for producing a gas mixture (G1 + G2) from nitrogen (N2) and carbon dioxide (CO2). The odor device (10) according to any one of claims 1 to 4, wherein the mixing system (20) is suitable for the production of the gas mixture (G1 + G2) from oxygen and argon. A smoothing device (10) according to any one of claims 1 to 4, characterized in that it uses the ternary or quaternary mixtures produced by the respective mixing system. 7. A scrubber (10) according to any one of the preceding claims, wherein the gases (G1, G2) used by the mixing system (20) for producing the gas mixture (G1 + G2) to be mixed with the liquid ( L) for sucking / flavoring, supplied in cylinders or in cryogenic containers or systems suitable for gas containment. The odor device (10) according to any one of the preceding claims, comprising, in the area at the exit of the mixing system 20, a three-way valve (25) suitable for controlling the flow of the gas mixture (G1 + G2) produced by a mixing system (20), towards an oil mill or dispenser (30), and against the storage container (28) of this gas mixture (G1 + G2). 9. A method for extracting a packaging such as a food preserving tray, wherein the product (PR), in particular the nutritional product, is packaged and secured, the method comprising the following steps: - providing a dewatering device (10) suitable for the generation and transmission of substances (G1 + G2 + L, OD) for ginning / flavoring in a gaseous form into the product (PR) packaging (CON) before the packaging seals sealably, the perfume device (10) : - mixing system (20) for generating a gas mixture (G1 + G2); a oil mill or sprayer (30) for dispensing / flavoring the liquid (L) and mixing it with a gas mixture (G1 + G2) produced and supplied by the mixing system (20); and a container (40) where the mixture (G1 + G2 + L) of the dispersed liquid and gas is stored and where the molecular exchange occurs between this gas mixture supplied by the mixing system and the dispersed liquid, thus obtaining the substance (OD) (a), wherein the odor device (10) including the mixing system (20) for the production of the gas mixture (G1 + G2) comprises only mechanical parts and pneumatic devices (20, 30 , 40) for the production, control and emission of OD (OD) for the odor / flavoring in the package (CON), intended for aeration, so that the device has a function that does not involve the use of electrical and / or electronic devices which may be a source the danger to safety in the environment in which it is installed (10). Desiccation process according to claim 9, wherein the oil mill or dispenser (30) is of such type that they comprise a Venturi hose for drawing the flavoring liquid (L) / flavoring and mixing it with a gas mixture (G1 + G2) which it produces and supplies a mixing system (20).
