Definitions

  • the present invention relates to an insulated container, in particular an itinerant trolley intended for the transport of fresh products, usable for example for the transport of meal trays.
  • the present invention relates in particular to trolleys for the transport of fresh products which can be used in particular for storing and transporting fresh products and for example meals before their distribution in planes, trains or hospitals and this at temperatures specific to the conservation of fresh products, that is to say close to 0 ° C.
  • the insulated containers are in this case slightly insulated, of light structure, for example only have a double wall, and are disposed or mounted integrally on displacement means, such as carts or castors or trains of casters for example.
  • the Applicant has demonstrated that in order to be able to carry out, for example long-term transport (30 hours) without freezing the products taking into account the doses of solid CO2 to be used, an additional device is necessary.
  • a container in particular an itinerant trolley, for the transport of fresh products, with isothermal walls of the type comprising a reservoir for refrigerant product in which the reservoir is arranged in the upper part of the container, and where a screen made of thermally insulating material, of dimensions slightly smaller than the internal section of the container and leaving at its periphery an annular space suitable for the free passage of gas is disposed horizontally below the tank, at a sufficient distance to delimit in the upper part of the container an area suitable for exchange by natural convection, and where the tank and the screen comprise means of attachment and / or support in the container, characterized in that it comprises at least one food compartment disposed in the container, below the screen plate, of dimensions substantially smaller than the internal volume of the container, a space remaining free around the co
  • solid carbon dioxide stored in the tank is used as the refrigerant.
  • the invention has the following advantages: . the products stored near the tank are protected from radiation and therefore from too low temperatures by the screen which forms a thermal barrier; . the sublimation gases can flow along the walls of the container, in the free space left between the screen and the vertical internal walls. During the initial sublimation, the cold gases descend to the bottom of the container, exchanging their frigories as they go. The hot atmosphere of the container rises by natural convection and passes into the area suitable for exchange by natural convection, in particular between the screen and the coolant tank where it cools.
  • the refrigerant is then a cooling agent for a radiant heat-conducting exchange surface which enables permanent cooling of the atmosphere by natural convection.
  • the food compartment may or may not be removable. There is free space around the compartment in the container.
  • the cold gas flowing along the walls of the container also flows along the walls of the compartment and cools it homogeneously.
  • the double envelope formed plays the role of a new thermal barrier with low insulation power, but compensated by the fact that the gas / solid exchange (without circulation) provides a low coefficient of thermal transfer.
  • the fresh products can optionally be stored on several trays arranged in the food compartment.
  • the food compartment can be opened, for example, at the front and / or rear to allow easy loading and unloading of fresh products, and in this case the refrigerant gases are in contact with fresh products during storage . It can also be airtight.
  • Carbon dioxide is however detrimental to the good conservation of certain fresh products. Therefore, in this case, the food compartment must be airtight.
  • cleats made of food-grade polyethylene permanently fixed to the walls of the container.
  • This internal structure makes it possible to load the products to be transported without particular precautions, its role being essentially to ensure the circulation of gaseous CO2 around the product whether or not the container is equipped with a double envelope.
  • the double envelope formed by a watertight metal box made of thin sheet metal will be deposited on the internal structure of the insulated container, that is to say on the lower battens and between the lateral battens, and its watertightness guaranteed on the front, loading side, by a metal door secured to the insulated door of the container.
  • the door can also be equipped with a plate fixed on its internal face, the plate being spaced from the internal face of the door to ensure the double envelope, the tightness of the compartment then being guaranteed by a seal at lips.
  • This seal makes it possible to seal the compartment even when the excess CO2 escapes through the door away from the container.
  • the containers according to the invention perfectly meet the conditions of temperature, temperature stability during storage and temperature uniformity for the preservation of fresh products.
  • the present invention also relates to the application of these containers to the storage of product at temperatures close to 0 ° C.
  • the rectangular container 1 consists of walls provided with insulating material 2.
  • a polyethylene plate 3 forming a screen is suspended by four suspension columns 4 from the upper wall 5 of the container 1.
  • This screen forming plate 3 delimits an area 6 suitable for exchange by natural convection where the hot gases which rise from the lower part of the container through the free space 8 between the screen 3 and the vertical walls 9 of the container cool in passing between the screen 3 and the reservoir 10 of coolant.
  • the containers further include in their lower part a grating 11 or cleats made of plastic material, for example polyethylene on which are arranged the fresh products to be transported.
  • FIG. 2 appears in section, and seen from the side, the same container 1 provided with the screen 3 suspended by the columns 4 and with the reservoir 10 placed in the zone 6.
  • Figure 3 appear in perspective the screen 3 and the tank 10 as they are arranged in the upper part of the container to form the natural convection zone.
  • the screen forming plate 3 is provided as described above with four suspension columns 4.
  • the reservoir 10 is a drawer made of 304L stainless steel provided with slides 12 capable of sliding in translation on slides 13 parallel to the drawer and themselves provided with pads of suspension 14 on the upper wall 5 of the container 1.
  • the studs 15 located at the end of the slides 13 on the side of the bottom 16 of the drawer 10 form a stop.
  • the drawer 10 is equipped, on the side opposite the bottom 16, with a handle 17 allowing the user to handle the drawer in translation when filling or checking the level of coolant.
  • the bottom 18 of the reservoir 10 is at a distance of a few centimeters from the screen 3.
  • a suitable convection zone is defined in the upper part of the container, for example if the bottom 18 of the drawer 10 is approximately halfway between the screen 3 and the upper wall of the container where the studs and suspension columns are fixed (4, 14, 15).
  • two superimposed plates can be provided, separated by washers.
  • expanded PVC is suitable as a material for the plate (s).
  • the tank 10 is a 304L stainless steel drawer with internal dimensions (in mm) 500 x 420 x 50 (thickness 12/10).
  • the screen 3 a 10 mm thick polyethylene plate, is suspended from 100 mm and the drawer is suspended from 10 mm from the wall 5.
  • the free space 8 is 30 mm at the front and at the rear and 55 mm on the sides.
  • the temperature between the reserve drawer provided with solid CO2 and the thermal barrier formed by the screen plate is at an average of -18 ° C. the temperatures measured in the container outside this zone have remained above -5 ° C., with a gap between the bottom and the top of the container of around 2 ° C. The tests lasted more than 5 hours at ambient temperatures of around 15 ° C. The products stored in the container remained between 0.5 and 2 ° C.
