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.
