Definitions

  • the subject of the invention is a new installation for the transport and / or storage of products sensitive to variations in temperature and humidity.
  • the present invention has two main fields of application: storage and transport.
  • the invention allows the realization of various storage facilities, such as silos, stores, warehouses, etc. and transport such as large containers, non-standard containers, pallet boxes, bags, cartons, packaging boxes, etc.
  • the products capable of being stored and / or transported, within the framework of the invention are on the one hand powdered or granulated products, such as in particular food products such as cocoa, and on the other hand any object or material sensitive to humidity and requiring limited humidity.
  • the invention allows the transport of a very wide range of goods between two countries with very different local temperatures.
  • An installation according to the preamble of claim 1 is known from document FR-A-2 163 344. This installation comprises two refrigeration units and a fan for reaching and maintaining the load located inside the container at a constant temperature in an interval extremely reduced.
  • the present invention aims to solve the aforementioned drawbacks, by proposing an installation for the transport and / or storage of products sensitive to temperature and humidity variations, of a new design, which makes it possible to avoid any deterioration of the products even when these undergo significant variations in temperature and / or humidity over time.
  • the solution according to the invention to solve the technical problem posed, consists of an installation according to claim 1.
  • the present invention makes it possible for the first time to control and order the physical phenomena of air / product balance, while avoiding the loss of quality of the product stored or transported.
  • these processing means comprise a heat exchanger.
  • the aforementioned heat exchanger is arranged on the path of circulation of air or neutral gas, in the vicinity of the products, preferably in the lower part of said internal enclosure.
  • this cavity is arranged substantially vertical to the upper opening of the internal enclosure, so as to create a chimney for the circulation of air or neutral gas.
  • the aforementioned heat exchanger further comprises a removable partition for separation with the products contained in the internal enclosure, produced for example in the form of a grid possibly connected to a plate disposed at the bottom of said internal enclosure.
  • this grid and this plate are made of a thermally conductive material, thus providing a thermal bridge between the internal volume of the aforementioned cavity and the internal enclosure.
  • the water content and the temperature of the product are generally homogeneous and the ambient air quickly equilibrates with the product without significant variation in its water content, even if this air has a temperature and hygrometry different from the equilibrium conditions.
  • Alternating humidity transfers for example following a daily cycle comprising a night minimum and a day maximum respectively lower and higher than the humid temperature of the internal air (dew point), are tolerable and do not cause loss product quality.
  • This installation comprises an internal enclosure 1 intended to contain the products to be transported and / or stored.
  • the shape and dimensions of this enclosure 1 can be any and will be chosen according to the shapes and dimensions of the products to be transported and / or stored.
  • the internal enclosure 1 is thermally insulated, for example by means of insulating panels known per se, and comprises at least one opening in its upper and lower parts, allowing the circulation of air (or possibly neutral gas) through the Pregnant 1.
  • the enclosure 1 has an upper central opening 2 and a plurality of lower lateral openings 3 which will be described later.
  • This installation also includes an external enclosure 5 surrounding said internal enclosure 1 which, in the example shown has a generally parallelepiped shape.
  • the external enclosure 5 is thermally insulated with the exception of at least one part, for example the lower part "a" of its side walls.
  • the internal wall of the enclosure 5 is thermally insulated along its upper horizontal wall 6 as well as along the upper part 7 of its four vertical side walls.
  • the thermal insulation of the bottom wall 8 of the enclosure 5 is ensured by the panel insulating the bottom of the internal enclosure 1 which rests on the bottom 8 of the external enclosure 5.
  • the installation according to the invention finally comprises a heat exchanger which will be disposed on the path of circulation of the air or of the moving neutral gas, in the vicinity of the products, for example in the lower part of the internal enclosure 1.
  • this heat exchanger comprises an open cavity 9 opening on the one hand to its upper part in the internal enclosure 1 and on the other hand, via channels joining the openings 3, in the volume between the indoor 1 and outdoor 5 speakers.
  • the cavity 9 can be produced in the form of a channel, for example a parallelepiped, extending longitudinally in the middle part of the internal enclosure 1, and communicating via an assembly channels 12 extending parallel and transversely to said channel, with the space between the interior 1 and exterior 5 enclosures.
  • the cavity 9 and the channels 12 will be produced in the panel insulating the bottom of the internal enclosure 1.
  • the cavity 9 will preferably be arranged vertically, relative to the opening 2, so as to create a "chimney" in which the moving air will circulate.
  • This heat exchanger will further include a removable partition 10 for separation with the products contained in the internal enclosure 1.
  • This partition will for example be produced in the form of a perforated plate forming a grid possibly connected to a plate 13 forming a floor on which the products to be transported and / or stored rest.
  • the cavity-grid-floor assembly thus constitutes the heat exchanger.
  • the shape of the fins (shown schematically in Figure 1) will reduce any drops of condensation to the outside of the cavity 9 at the orifice opening into said cavity and outwards at the level of the orifice opening into the space between the internal 1 and external 5 enclosures.
  • the cavity 9 is accessible from its upper part and it is possible, for example, to introduce therein absorbent and / or adsorbent products and / or of a nature to increase the thermal mass of the exchanger.
  • the non-insulated part of the side walls cools the descending air and starts moving in the direction indicated by the arrows.
  • the air entering the cavity 9 is heated (for example to a temperature of 23/24 ° C) and its relative humidity decreases to a value lower than the relative humidity of air-product balance (for example 65 to 70%).
  • the air heats up on contact with the product (for example up to a temperature of 25 ° C) while being charged with humidity (tendency towards air-product equilibrium).
  • the air reaches a temperature and a relative humidity substantially equal to that of the product (for example a temperature of 25 to 26 ° C and a relative humidity of about 75%).
  • the homogeneity and progressiveness of the cooling and drying are obtained by the regulation of heat transfers and humidity transfers.
  • the invention allows the transport and / or storage of a wide range of products. These products can be transported both in bags and in bulk, which allows to take full advantage of the economic interest of the container.
  • the homogeneity and progressiveness of the cooling and drying guarantees the perfect preservation of the initial qualities and properties of the products.
  • the present invention is based on a static heat exchange between a product contained in a partially or completely enclosed volume and the ambient interstitial gas (possibly air).
  • One of the original features of the invention is not to use mechanical means to control the temperature and / or the hygrometric degree of a gas, but to use a static heat exchanger.
