Definitions

  • the invention relates to a fan for cold gas circulation in a food freezer, the fan having fan blades mounted on a hub.
  • the cold gas atmosphere can for example, by evaporation of a liquefied gas, eg. B. of liquid Nitrogen can be generated.
  • a liquefied gas eg. B. of liquid Nitrogen
  • fans for the necessary cold gas circulation are provided.
  • the food for example, placed on a conveyor belt, which conveys the food through a tunnel-like housing. By doing tunnel-like housing is maintained a cold gas atmosphere, wherein usually several fans provide the necessary cold gas circulation.
  • Object of the present invention is therefore to provide a fan for Provide cold gas circulation in a food freezer at the same time meets high hygiene requirements and has a high efficiency.
  • the stainless steel sheets are formed as a circular discs. In Near the circumference, the discs each have holes for attachment of the Fan blades on.
  • the stainless steel sheets can also be 5-, 6-, or 8-square Be formed discs. The fan blades are sandwiched arranged between the two discs.
  • the stainless steel sheets Cutouts that prevent a buildup of food particles. In addition, this is an all-round cleaning inside and outside of the Fan wheel allows.
  • the cutouts can be designed in different ways be.
  • the stainless steel sheets are preferably made by laser technology. in the Stainless steel plates can be used in contrast to the production of stainless steel hubs be manufactured inexpensively by laser. Alternatively, the stainless steel sheets also be milled
  • the fan blades exist advantageously made of plastic. But they can also be made of stainless steel.
  • the fan blades have an aerodynamically optimized profile (helicopter rotor) on.
  • the fan according to the invention can be used for all conceivable food freezers be used, where high demands on hygiene and efficiency be put.
  • the fan is suitable for cabinet, tunnel and Spiral freezer.
  • the fan according to the invention optimal for use in the Food technology suitable.
  • dispensing with corrosive materials can a chemical influence of the food can be excluded.
  • inventive design of the fan dead spaces Contamination of food by adhering contaminants can reliably prevented.
  • the fan can be inexpensive Way be made using laser technology.
  • FIG. 1 shows two identically constructed stainless steel sheets in the form of a disk, which make up the hub of the fan.
  • the implementation 5 for the fan shaft and the bores 2, 3 for receiving the fastenings for the fan blades are superimposed.
  • Through the recesses 4 is on the one hand reduces the mass of stainless steel sheets and on the other hand the Improved accessibility for cleaning purposes.
  • Figure 2 is on the left side a completely zusuümen composeer fan in shown in perspective from above, while on the right side of shown below.
  • Figure 2 In the middle is a detail view of the hub with the Stainless steel sheets 1 and 2 and the attached therebetween fan blades 8 shown.
  • the complete fan has a motor 6, which via a shaft 7 from the Stainless steel sheets 1 and 2 composite hub drives.
  • the fan blades 8 are each formed at one end in the stainless steel sheets 1 and 2 Inserted intermediate space and, for example by means of bolts or screws to the Stainless steel sheets 1 and 2 attached.
