Description

Title of the invention: Container decontamination device for winemaking or similar purposes and method of implementing this device

[0001] The present invention relates to the field of decontamination using containers for the production of wine or the like, such as barrels, stainless steel or concrete tanks, casks, amphorae, etc., by means of ultraviolet radiation, in particular pulsed light.

[0002] In the known prior art, several methods are used for decontaminating wine barrels. These methods employ, for example, steam, hot water under pressure, ultrasound, ozonated water, a mixture of sodium hydroxide and permanganate, and / or a sulfur wick. This last method is the most widespread for decontaminating wine barrels. However, the use of sulfur is not without risks to human health, which is why there is a need to find alternative solutions to this method.

[0003] Decontamination by ultraviolet radiation proves to be a more effective, more ecological and healthier solution than the aforementioned decontamination methods.

[0004] More specifically, it is known to use ultraviolet radiation lamps or UV-C lamps which are inserted into the container to be decontaminated.

[0005] Document ES 1265944 U discloses a container decontamination device for the production of wine or other alcoholic beverages using ultraviolet radiation. The device comprises a main body containing an ultraviolet radiation lamp, or UV-C lamp, and a retractable sleeve that can slide along the main body between: a rest position in which the UV-C lamp is fully inserted inside the main body, and an operating position in which the UV-C lamp extends out of the main body at a second lower end thereof. The device also includes actuating means for sliding the sleeve between the two positions. A spring holds the UV-C lamp in the rest position until the actuating means are activated.A means of retention is also described to compensate for the action of said spring and to hold said UV-C lamp in said container in its position of use.

[0006] This device requires the use of a support grid equipped with feet and resting against the container. The UV-C lamp is then held in position on the grid and subsequently inserted, through the grid, into the container. This configuration has the disadvantage of making the installation of the UV-C lamp in said container, long and tedious.

[0007] US2020 / 0230273 Al addresses this drawback by proposing a support in the form of a base fixed directly onto a retractable sleeve. More specifically, this document describes a portable ultraviolet radiation decontamination device for a container used in winemaking. The device comprises: a main body, an ultraviolet radiation lamp or UV-C lamp fixed to a second lower end of said main body, a retractable sleeve mounted to slide on said main body between an operating position and a resting position, and a means for gripping said device. This gripping means is fixed to a first upper end of said main body. When said UV-C lamp is inserted into said container, said retractable sleeve rests, via said base, against said container and slides along said main body.The retractable sleeve is then in a working position in which the UV-C lamp extends outside the retractable sleeve at its lower end. When the UV-C lamp is removed from the container, a spring exerts a restoring force, allowing the retractable sleeve to slide along the main body to cover the UV-C lamp, and the retractable sleeve then returns to its resting position.

[0008] Although this device facilitates the installation of the UV-C lamp, it presents drawbacks when the UV-C lamp is removed by an operator. Indeed, due to the spring force exerted during removal, the operator must apply resistance to prevent the device from being released too quickly, which could damage the UV-C lamp. Furthermore, the device's gripping mechanism consists of a tubular cap and does not allow for a secure hold by the operator, thus making the use of the UV-C lamp difficult and potentially damaging it if handled improperly. Therefore, there is a need to facilitate the installation, removal, and handling of the device.

[0009] Furthermore, the shrink sleeve described in US2020 / 0230273 is transparent; therefore, if the UV-C lamp is switched on before being inserted into the container, the operator is at risk of light exposure. Exposure to ultraviolet light can be very harmful to health.

[0010] Although document ES 1265944 U describes an opaque retractable sleeve to limit light exposure, it is nevertheless necessary, before inserting the UV-C lamp into the container, to switch it on and verify that it is indeed switched on. The operator is then exposed to the ultraviolet radiation from the UV-C lamp. Therefore, there is a need to improve the safety of operators handling such a device.

[0011] The present invention aims to remedy these various drawbacks by proposing a container decontamination device, for the manufacture of wine or similar, which is easy to install and handle and ensures the safety of operators.

[0012] To this end, the present invention relates to a decontamination device using ultraviolet radiation, in particular pulsed light, for a food container used in the production of wine or other alcoholic beverages, this decontamination device comprising: • A main body comprising gripping means fixed to a first upper end of said main body; • An ultraviolet radiation lamp or UV-C lamp fixed to a second lower end of said main body; • A retractable sleeve mounted to slide on said main body between a rest position in which said UV-C lamp is fully inserted into said retractable sleeve and an operating position in which said UV-C lamp extends out of said retractable sleeve at a second lower end of the latter against the action of elastic return means in the rest position; • A base located on said second lower end of said sheath.

[0013] The decontamination device according to the invention is characterized in that it includes actuation means configured to allow, when removing said device from said container, a progressive return of said retractable sheath from said position of use to said rest position.

[0014] According to an additional feature of the invention, the decontamination device includes a device for activating the UV-C lamp. The decontamination device also includes a means for detecting darkness, such as a light sensor. This feature ensures operator safety. Indeed, as long as the light sensor detects ambient light, the device for activating the UV-C lamp cannot be switched on.

[0015] According to another additional feature, the decontamination device includes means for detecting the position of the retractable sheath. Preferably, these position detection means may include a retractable sheath position sensor and an end stop, or alternatively, a mechanical lever switch. The position sensor is configured to detect the end-of-travel position of the retractable sheath in the operating position. The UV-C lamp ignition device cannot be activated until the position detection means have detected that the retractable sheath has reached the end of its travel.

[0016] This configuration ensures that the decontamination device is correctly inserted into the container to be decontaminated, more specifically, that the lamp UV-C is fully inserted inside the container and is no longer visible to an operator, in order to avoid their exposure to ultraviolet radiation.

[0017] Thus, the UV-C lamp can only be switched on when it is completely in darkness and the retractable sleeve has reached the end of its travel.

[0018] According to another additional feature, the device includes means for retaining the latter in the container to be decontaminated when the device is in the position of use.

[0019] According to another additional feature, the retaining means are located on a first upper end of the UV-C lamp.

[0020] According to another additional feature, the retaining means comprise at least three retaining tabs, preferably four retaining tabs. Said retaining tabs are preferably metallic.

[0021] According to another additional feature, the retaining tabs are configured to deploy after the device is inserted into an opening in the container to be decontaminated.

[0022] Thus, once the device is inserted into this container to be decontaminated, it is held in position and locked against the container to be decontaminated by means of the base and the retaining tabs.

[0023] According to another additional feature, the means for gripping the decontamination device preferably take the form of a handle. This feature makes it easier for an operator to grip the decontamination device.

[0024] According to another additional feature, the device includes means for positioning the device in a vertical or horizontal position. Advantageously, the positioning means are in the form of hooks.

[0025] According to another additional feature, the shrink sleeve includes air evacuation means which allow the heat dissipated by the UV-C lamp during its use to be evacuated, preferably formed by evacuation orifices.

[0026] According to another additional feature, the device includes means for measuring the radiation emitted by the UV-C lamp, preferably consisting of a photodiode. This feature makes it possible to detect the wear level of the UV-C lamp.

[0027] According to another feature of the invention, the decontamination device includes means for connecting a power supply to a power supply and control station. This station advantageously comprises a trolley equipped with a docking station for said decontamination device. This power supply and control station is also preferably equipped with means for movement and means for... nipulation, allowing the operator to move easily around the containers, thus facilitating the use of the decontamination device.

[0028] The power supply and control station also includes a control panel, advantageously equipped with a control screen preventing the operator from intervening directly on the decontamination device during its operation.

[0029] This power supply and control station can also be provided with auxiliary connection means for connecting other types of decontamination tools to this station, for example.

[0030] The power supply and control station includes means for connection to an electrical power supply network.

[0031] In a possible variant, it may, where appropriate, also accommodate an independent power supply, such as at least one rechargeable battery.

[0032] The invention further relates to a method of implementing a decontamination device according to the invention for the decontamination of a food container for the manufacture of wine or other alcoholic beverages, by ultraviolet radiation, in particular of the pulsed light type, this container having at least one opening.

[0033] The process is characterized in that it comprises: • a step of applying the base to the second lower end of the shrink sleeve above the opening of the container; • a step of engaging the UV-C lamp inside the container through said opening by pushing the retractable sleeve from its rest position into its position of use, against the action of elastic return means; • a step of attaching the decontamination device to the container; • a verification step including the verification of at least two safety conditions include the following: • the darkness detection means detects that the UV-C lamp is placed in darkness; • the retractable sleeve position sensor detects the end of its travel when it comes to a stop against the container; • a transmission step including the transmission to the power supply and control station and / or the UV-C lamp ignition device of information to verify safety conditions; • a validation step in which: • if at least one of the two safety conditions is not met then an alert is issued to the power supply and control station and / or to the ignition device of said UV-C lamp in order to control and / or repeating the previous steps; • If all safety conditions are verified, the UV-C lamp ignition device 4 can then be activated.

[0034] Other features and advantages will become apparent in the following detailed description of a non-limiting embodiment of the invention illustrated by the attached Figures 1 to 5, in which:

[0040] The present invention relates to a decontamination device 1 of a container 100 for the manufacture of wine or other alcoholic beverages by ultraviolet radiation and more particularly by pulsed light.

[0041] As illustrated in Figures 1 and 2, the decontamination device 1 comprises a main body 2, preferably cylindrical. This main body 2 has, at a first upper end, gripping means advantageously in the form of a handle 210. The decontamination device is also equipped with a UV-C lamp 4, preferably a pulsed light lamp. The main body 2 is extended by the UV-C lamp 4, which extends substantially along the longitudinal axis of the main body 2. More specifically, the UV-C lamp 4 is fixed to a second lower end of the main body 2.

[0042] The decontamination device 1 also includes a retractable sleeve 3 comprising a first upper end and a second lower end. The retractable sleeve 3 is provided with a base 5. This base 5 is located on the second lower end of the retractable sleeve 3.

[0043] In these figures 1 and 2, the retractable sleeve 3 is positioned in a rest position in which the UV-C lamp 4 is fully inserted inside the retractable sleeve 3.

[0044] Fig. 3 illustrates the retractable sleeve 3 in a working position in which the UV-C lamp 4 extends outside said retractable sleeve 3 at a second lower end of the latter.

[0045] More particularly, the retractable sleeve 3 is slidably mounted on the main body 2 between a rest position in which said UV-C lamp 4 is fully inserted into said retractable sleeve 3 and a working position in which said UV-C lamp 4 extends out of said retractable sleeve 3 at a second lower end of the latter.

[0046] The retractable sleeve 3 comprises a main portion 32 and a connecting portion 31. The main portion 32 extends from the second lower end of the retractable sleeve 3 to the connecting portion 31. The connecting portion 31 is continuous with the main portion 32 and extends from the main portion 32 to the first upper end of said retractable sleeve 3. The diameter of the connecting portion 31 is smaller than the diameter of the main portion 32. The retractable sleeve 3 slides on the main body 2 via the connecting portion 31.

[0047] The decontamination device 1 also includes elastic return means, preferably consisting of a spring 20. The spring 20 is fixed at the first upper end of the retractable sleeve 3. More specifically, the spring 20 is fixed to the connecting portion 31 and is positioned around the main body 2, which is preferably cylindrical. When the decontamination device 1 is withdrawn from the container, the elastic return means allow the retractable sleeve 3 to return to its resting position.

[0048] Furthermore, the decontamination device 1 includes actuation means configured to allow, when removing said device 1 from said container 100, a progressive return of said retractable sleeve 3 from said operating position to said rest position, ensuring throughout that the base 5 remains in contact with the opening 108 of the container 100. This avoids any risk of exposure to ultraviolet radiation if, as will be explained in more detail below, the lamp remained in operation despite the specific safety features provided by the invention.

[0049] Fig. 4 illustrates a power supply and control station 10 to which the decontamination device 1 is connected by power supply connection means 211.

[0050] It should be noted that these power supply connection means 211 are advantageously connected in such a way as to be able to be disconnected at the power supply and control station 10. In particular, said power supply connection means 211 may be equipped, at their end opposite the decontamination device 1, with a connection plug, preferably of the male type, designed to cooperate with a connection plug, preferably of the female type, equipping the power supply and control station 10. This configuration allows the possible connection of this power supply and control station 10 to other types of decontamination tools by UV-C radiation.

[0051] The power supply and control station 10 includes a trolley 101 equipped with means of movement such as, for example, wheels. The trolley 101 also includes means for handling, in particular in the form of handles.

More specifically, the retaining elements are formed by retaining tabs 411. These retaining tabs 411 are preferably metallic. The retaining elements are configured to deploy once the retractable sleeve 3 has reached its end of travel. Thus, the container 100 is gripped between the base 5, whose shape matches that of the container 100, and the retaining elements. This configuration allows the decontamination device 1 to be fixed to the container 100 and prevents its accidental removal. Removal of the decontamination device 1 is only possible by applying an external pulling force to it, for example, exerted by an operator, a pulling force greater than the holding force exerted by the retaining tabs 411 on the container 100.
