Definitions
- the present invention relates to the storage of a set of products in a storage cell comprising improved sealing means, with implementation of a flow of air flowing through the set of products, and in particular, but not exclusively, a reversible air flow. It finds particular application for the temporary storage of a set of food products, such as for example and non-exhaustive dairy products or not milk type fermented yogurts, farm yogurt, yogurt, dessert creams, cheeses, fruits, vegetables, prepared meals, with modification or maintenance of the temperature and / or humidity of the products by means of said air flow.
- storage cells such as that described in the international patent application WO99 / 11141 or in the French patent application FR2871222, for the temporary storage of a set of products.
- food products and in particular dairy or non-dairy products such as, for example, yogurts, yoghurts, cheeses, etc., packaged and positioned on a storage medium, in particular of the pallet, rack or trolley type, with the implementation of a feed of air conditioning through this set of products so as to adjust the temperature / and or humidity of the products.
- This air flow can for example be a cold air flow having a controlled temperature and optionally a controlled relative humidity rate, so as to allow the cooling or the low temperature storage of the products, such as for example yogurt fermented, yogurt, cheeses, if any with controlled moisture products.
- This air flow can also be a flow of hot air having a controlled temperature and optionally a controlled relative humidity rate, so as to allow the heating of the products, if necessary with a controlled humidity of the products.
- This type of hot air flow is for example used to store fermentable products, such as for example farm yogurt, by heating them so as to ferment during their stay in the cell with a controlled fermentation time.
- This air flow can also be a flow of air at the temperature of the products, where appropriate with a controlled relative humidity rate, so as to allow the products to be kept in temperature for the duration of storage in the cell, the case with controlled humidity products.
- the air flow is created by means of at least one fan which is positioned at the rear of the storage cell and which in operation makes it possible to blow a flow of air. from the back to the front of the cell.
- a seal on the top and on both sides of the set of products is achieved by means of three tarpaulins respectively. sealing, which inflate under the action of air pressures in the storage cell when the fan is running and which, by swelling, come to press against the set of products so as to seal on the top and on both sides of the set of products. Thanks to the implementation of this seal, the air flow is forced to flow from the back to the front of the cell through all products.
- French patent application FR2871222 describes a storage cell of the same type as that described in international patent application WO99 / 11141, but which has been improved by implementing for the upper sealing sheet a counterweight fixed to the rear end of the upper sealing sheet, a crossbar rotating supporting the rear portion of the upper sealing tarpaulin, and a movable bar which is integral with the upper sealing tarpaulin, being more particularly incorporated in a sleeve of the upper sealing tarpaulin.
- This movable bar rotates in rotation about a horizontal fixed axis.
- the seal being provided solely by the swelling of the sealing sheets under the action of the air flow back / front, there is a risk of loss of sealing more or less important, especially in in the event of a malfunction of the fan, for example in the event of an accidental drop in the fan's air flow or an inadvertent shutdown of the fan.
- This first disadvantage is aggravated in the case of the storage cells described in the French patent application FR2871222, because of the implementation of the counterweight in the rear portion of the upper sealing tarpaulin.
- the storage cells described in the international patent application WO99 / 11141 and in the French patent application FR2871222 also have the second disadvantage of being unidirectional, that is to say, to be designed and to be able to operate only with a flow of air flowing in the direction allowing the inflation of the sealing tarpaul a flow of air circulating in the storage cell from the rear to the front of the storage cell.
- the main object of the present invention is to propose a new storage cell, which is of the type described in the international patent application WO99 / 11141 or in the French patent application FR2871222, and which has been perfected so as to overcome the first disadvantage referred to above and / or the second disadvantage referred to above.
- the cell for storing at least one set of products and in particular a set of products arranged on at least one storage medium, and more particularly on at least one pallet, trolley or rack has the following specifications.

- the second sealing element of the invention does not have the function in its active configuration of blocking forward said first flexible sealing element, but conversely exerts on a portion of the first flexible sealing element a mechanical pressure, which is oriented towards the interior of the housing and in the direction opposite to said wall of the cell with respect to which said first flexible sealing element is able to inflate, and which allows to move said first flexible sealing element relative to said wall of the cell with respect to which said first flexible sealing element is able to inflate.
- This mechanical pressure which is directed towards a set of products positioned in the housing of the cell, allows to apply or maintain applied at least a portion of the first flexible sealing member corresponding against said set of products.
