Definitions
- the present invention relates to a cooling device according to the preamble of claim 1.
- FR 2 762 190 describes an installation for manufacturing fresh dough which includes a conveyor line along which are arranged pulp processing stations. Treatments include shaping, line cooling and cutting into pieces of the dough. The dough is cooled by the controlled deposit of dry ice on it.
- This deposition is carried out by a controlled carbon dioxide snow deposition device which comprises solenoid valves for expansion of liquid CO 2 arranged above the conveyor and connected to a source of liquid CO 2 . Cylindrical blows are connected to the solenoid valves in order to guide the jet of dry ice towards the dough on the conveyor.
- a protective cover open towards the bottom surrounds the blunderbusses and the solenoid valves in order to channel towards a device for CO 2 extraction, the gaseous CO 2 which is produced.
- a drawer is provided in order to close the lower opening of the hood, during the non-use phases of the device for depositing controlled dry ice.
- the spread out dough is transferred by the conveyor below the blast pipe openings, and the production of dry ice is triggered when the dough arrives.
- the dry ice production rate is mainly regulated depending on the speed of the conveyor and the thickness of the dough to ensure the desired cooling.
- Pulp production lines are often used in humid environments, which causes the deposition of water drops from condensation on the blunderbusses and the solenoid valves. As a result, the snow carbon dioxide becomes wet and no longer falls regularly on the dough, but falls into lumps.
- the blinkers are fixedly connected to the solenoid valves and that the attachment is difficult to release due to the slagging thereof, they are difficult to clean. Often it is necessary to wait until the fasteners are thawed.
- the invention aims to overcome these drawbacks and to propose a carbon dioxide snow deposition device which allows snow deposition carbon control better and more reliable.
- the invention relates to a device for cooling the aforementioned type, with the characteristics defined in the claim 1.
- Figure 1 shows schematically an installation of production 2 of food products to transform a product pasty 4 in kneader in pieces or individually conditioned portions 6 before packaging in batches and, if necessary, cooling in the chamber Cold.

It has, on its lateral side, a cover 87 in order to allow the mounting of the cover. It has two passage openings 88, 90 in its end surfaces.
- the protective cover 86 is connected via a gas sheath 92 to an extractor in order to extract the gaseous CO 2 in the direction of arrow 94 in FIG. 2.
- a sensor 96 for speeds of the conveyor line 8 and / or presence of product 14 is placed above the conveyor and fixed in the cover 86. Alternatively, it can be arranged on the side of the conveyor.
- the distribution cabinet 22 comprises, on the one hand, means for supplying CO 2 100% liquid, and, on the other hand, means for supplying CO 2 100 % gaseous.
- the liquid CO 2 supply pipe 52 of the cabinet 22 is connected to a conventional gas vent valve 120.

- the carbon dioxide snow deposition device according to the invention works as follows.
- the cabinet 22 When the distribution cabinet 22 is started and before the production of the food product 14 is started by spreading, the cabinet ensures a permanent production of gaseous CO 2 and introduces it via the CO 2 collecting pipe 66 gas and quick couplings 76 in the blunt pipes 78.
- the CO 2 has a temperature significantly below ambient temperature, preferably at most at 0 ° C., and contains no trace of humidity.
- the CO 2 gas fills the blinkers 78 completely and is evacuated through the lower orifices 79 thereof.

- the permanent inerting of the nozzles of the expansion solenoid valves 80 there is no risk of clogging thereof.
- the interior of blunderbouts 78 being completely free of moisture, the snowflakes carbon dioxide do not agglomerate.
- the amount of snow carbon dioxide is well controlled and precise, so that it deposits a layer of dry ice 100 regular without lumps on the dough 14.
- the permanent CO 2 gas sweep prevents the introduction of dust into the blinkers 78 and the orifices of the solenoid valves 80.
- the gaseous CO 2 has a maximum temperature of 0 ° C, frozen drops of condensed water which may be present on the external surface of the blobs do not thaw. Consequently, a drawer for closing the lower opening of the cover is not necessary, and no dripping occurs.
- the quick connectors 76 allow an easy and quick detachment of the blinkers 78 for maintenance and easy cleaning of the device.
- the actuation of the quick couplings 76 is easily possible and without the need to wait a long time thanks to the gel reduced quick couplings 76 compared to an arrangement of fittings on the solenoid valves. This leads to increased availability of the installation.
- the in-line cooler 20 can be installed on the production line in any place where a sufficient surface large conveyor is available.
- the production of carbon dioxide snow is timed so as to deposit a layer of carbon dioxide snow 100 on each cut piece 18.
