Definitions

  • the present invention relates to the field of cryogenic freezing processes and equipment called “IQF” (this technical field speaks of freezing called IQF for "Individually Quick Freezing"), for the freezing of individual products such as fruits, seafood, meat products and vegetables.
  • IQF cryogenic freezing processes and equipment
  • IQF freezing is carried out in particular in liquid nitrogen baths or else in rotating apparatus of the drum or churn type.
  • This equipment is therefore characterized either by a high gas consumption or by a large space requirement.
  • One of the objectives of the present invention is then to propose a new technical solution to the problem developed above.
  • the present invention proposes a cryogenic treatment operating in "batch" mode, which implements a movement during the cooling / freezing phase in order to preserve the individual character of the products to be treated (and therefore avoid agglomerating them), the setting in motion being able to be carried out by vibration or else by rotation.
  • the system is modular, it allows both treatments on classic products and so-called “IQF” treatments (individual products).
  • the carriage is secured to the cell by any suitable means (floor guide, clipping system, etc.), and the cell includes means (for example 2 gear motor shafts in waiting to make contact with the loaded drum) to rotate the drum(s) once a freezing cycle is initiated.
  • suitable means for example 2 gear motor shafts in waiting to make contact with the loaded drum
  • an industrialist specializing in seafood products who wants to freeze fish, will use a classic trolley with shelves in the cell, while when he wants to freeze mussels (without shells) he will use a (or more) drum trolley(s) in its cell or will set the trolley in vibration after having loaded the molds into a shelf.
  • a farmer who wants to freeze meat will use a classic rack trolley in the cell, while when he wants to freeze his cut vegetables, he will use one (or more) drum trolley(s) in his cell, or else will vibrate the trolley after loading the cut vegetables into a shelf.
  • the drum(s) Once the drum(s) have been clipped, it closes the door and launches its freezing cycle, the shafts will then start to rotate (very slowly) which will allow the drums to rotate. The products will therefore be cooled while being in motion and will thus be able to be frozen while remaining individual.
  • the trolley and its drum(s) can be easily detached from the freezing cabinet in order to be emptied of the frozen products that they contain. If necessary, a device allows this operation (door, tilting of the drum(s), rotation in opposite directions, etc.).
  • FIG. 1 gives a partial schematic representation of a cell according to the invention, in an embodiment comprising two drums, and an example of such a drum is illustrated in Figure 2 .
  • FIG. 3 appended gives a partial schematic representation of a cell in accordance with the invention, in an embodiment comprising a system for vibrating the carriage which has been loaded into the cell (vibration system in the lower part).
  • the present invention is committed, in the same installation, to being able to process, according to what the user site produces according to the period in question, "normal" products when the production requires it, and IQF products (i.e individual, such as fruits, vegetables, meatballs, etc.) when production requires it.
  • IQF products i.e individual, such as fruits, vegetables, meatballs, etc.
