Definitions

  • the invention relates to a device for freezing and / or cooling of Articles with a cold room, with a transport device for conveying the items is equipped by the refrigerator and at least one Cold gas generating device for generating a cold gas atmosphere in the Refrigerator and at least one fan for distribution of the cold gas, wherein the fan is connected to a drive motor.
  • Such cooling devices are used, for example, for frosting foods used.
  • tunnel freezers for example, the food conveyed continuously through a tunnel-like cooling space on a conveyor belt.
  • a cold gas generating device for. B. in the form of a copessiggaseinsprühdüse arranged.
  • the liquid gas sprayed into the cold room is evenly distributed in the cold room by fans. This will be through the food transported through the refrigerated compartment is evenly cooled or frozen.
  • motors are used to drive the fans, which are arranged outside the refrigerator. In this way, the heat loss be removed from the engines easily.
  • Hygiene problems also arise through Cables and cable shafts as well as other units, which are on the tunnel freezer are mounted.
  • the present invention is based on the object, damage to the motors by preventing detergents and improving hygiene.
  • This object is achieved in that the drive motor in one housed separate from the refrigerator engine compartment. Due to the arrangement of the Drive motor and possibly other components in the engine compartment, these facilities do not pollute anymore.
  • the cowling of the engine compartment should be removable to allow one to Maintenance has access.
  • the cover is made of plastic made so that it is easily removable.
  • she can also use one Hinge hinged be mounted. It can also consist of stainless steel.
  • in the Case of a version of the panel in plastic are slightly different Dyeing possible, which can increase the optical attractiveness.
  • the panel is conveniently mounted with quick-release screws, so that it can be removed quickly.
  • the panel is advantageously with a circumferential seal mounted.
  • a Cooling air supply and an exhaust air discharge provided. It is advantageous to sucked in one end of the device room air, sucked through the engine compartment, wherein the waste heat of the drive motors is received, and finally via a Exhaust air discharge at the other end of the device derived.
  • the exhaust air discharge opens in a Suction shaft, which is provided with a suction device and exhaust gas from the Cold storage takes up.
  • a suction duct is usually in one Freezer that works with cold gas, anyway available.
  • Exhaust air removal is preferably taken care that no detergent from the refrigerator enters the engine compartment.
  • a filter used at least at the Intake side a filter used, so that no dust or the like is sucked in with.
  • a cryogenic tunnel freezer is run in reverse, d. H. of the Suction chute is located in the area of the product input. Unless in synchrony to be driven, the cooling air flow through the engine compartment can be easily turned and be sucked off at the product outlet.
  • a development of the inventive concept provides that the engine compartment a Has cold gas supply.
  • the drive motors in the engine compartment by slightly outflowing cold nitrogen gas, which in a tunnel freezer is available anyway, to be cooled.
  • the cold gas from a liquid gas source generated.
  • the resulting cold gas can also be used for other applications become.
  • the cold gas supply or the evaporator on a temperature-dependent control.
  • the invention can be used in all conceivable devices for freezing and / or cooling be used by objects where the objects in a refrigerator be exposed to a cold gas atmosphere by means of fans in the refrigerator is evenly distributed.
  • the invention in Facilities for freezing and or cooling food in so-called Freezers, especially tunnel freezers are used.
  • the arrangement of the drive motors in a separate engine compartment is the hygienic situation significantly improved.
  • the term of the Drive motors significantly extended, without requiring additional space inside the freezer is necessary. A simple replacement of the drive motors is guaranteed.
  • the figure shows a tunnel freezer for freezing food.
  • the Tunnelfroster has a tunnel-like refrigerator 1, through the food on a conveyor belt 4 are transported in the direction of tape 3.
  • the refrigerator 1 is at least one liquid nitrogen injection 5 attached, the liquid nitrogen the food is spraying.
  • fans 6 By means of fans 6, the evaporation of the liquid nitrogen nitrogen gas atmosphere in the refrigerator 1 evenly distributed.
  • the fans 6 are by means of drive motors 7, which in a separate Engine room arranged are driven.
  • a cooling air supply 9 are the Drive motors 7 cooled in the engine compartment 2.
  • a suction duct 10 In the entrance area of the tunnel freezer is a suction duct 10 attached.
  • the cold gas in the cooling chamber 1 flows in Opposite direction 8 to the transport direction 3 of the food and leaves the Tunnel freezer over the suction duct 10.
  • the engine compartment 2 has a Exhaust vent 11, which opens into the suction duct 10. In this way is achieved that by means of the suction device 12 room air over the cooling air supply. 9 through the engine compartment 2 and through the exhaust air discharge 11 in the Suction duct 10 is sucked. In the suction chute 10 mixes the from Engine compartment 2 withdrawn, heated by the waste heat of the drive motors 7 Cooling air with the exhaust gas withdrawn from the refrigerator 1 and is finally over blown an exhaust passage 13 into the open air.
