Definitions

  • the invention relates to a device for cooling packaging.
  • this is cooling of packaging whose contents are filled in at high temperatures has been.
  • Such packaging is, for example Plastic bags in which, for example, food or other products such as chemical products at high temperatures be filled in.
  • the problem here is that the temperature of the filled products sometimes above the melting point of the plastic lies, causing it to be destroyed or damaged the packaging can come.
  • melting or softening of the plastic packaging causes it to stick together Packaging is coming. This is when packaging the individual Packing in a common box or similar adversely and can also destroy the packaging to lead. It is also possible that by the strong heating chemical substances in the packaging enter the product. This must be avoided especially when packaging food become.
  • a packaging device is known from EP 0 699 586 A1, with the high temperature products in a film tube be filled with the temperature of the product above the Melting temperature of the film tube is.
  • the film tube is welded together after filling the product Bag divided. This is used to cool the film tube sprayed with a coolant, especially water. in this connection sufficient cooling cannot usually be achieved, so due to the temperature of the product despite the Cooling can damage the bags.
  • An increase is the heat dissipation by spraying the bags heavily also not possible because the high Water pressure can be damaged.
  • thermoplastic material such as adhesive
  • a device is known through which thermoplastic material, such as adhesive, is molded to then easier to pack.
  • thermoplastic material such as adhesive
  • the thermoplastic material is made by a Cutting device cut into individual pieces, being too this time the outer layer of the thermoplastic Material has already hardened somewhat.
  • a paddle wheel-shaped device is provided for shaped pieces.
  • the coolant is in one Circulation in the area of the paddle wheel from the container removed, cooled in a heat exchanger and on the Paddle wheel opposite side of the container again fed.
  • the object of the invention is to provide a device for cooling To create packaging with which, in particular, at Food packaging has achieved adequate cooling can be.
  • the device according to the invention has a cooling channel, in the coolant is contained.
  • the packaging will moved through the cooling channel and out of the cooling channel through a Removed device. Moving the packaging can be done by creating a flow in the coolant, so the packaging through the cooling trough on the bottom the coolant flow are transported. Likewise it is possible to use rakes or other packaging To move conveyors through the cooling trough.
  • the cooling device according to the invention has a Spray device on.
  • the spray device will Packaging as it is transported through the cooling troughs are sprayed with coolant.
  • the spraying takes place preferably from above. While the packaging in the coolant will float, the bottom of the packaging of the coolant in the cooling channel and cooling the top by spraying it with coolant.
