Definitions
- the invention relates to a goods counter, in particular a refrigerated counter for light perishable foods, such as meat products.
- the goods are stored on a counter display.
- a circulating air flow is conducted around it.
- Such counters often display Filter through which the air flow passes and that for filtering out Hovering particles and microorganisms such as bacteria or the like. serves.
- the invention has for its object to improve the hygiene of such a counter in general.
- the solution to this problem is to arrange the filter at least partially in a static electrical or magnetic field.
- the advantage of this configuration lies in the fact that an electrical or magnetic gradient acts on charged particles or particles having a partial charge contained in the circulated air flow. As a result, a force greater than that caused by the flow can be exerted on the particles mentioned Entraining forces ". Charged particles are thus retained with the participation of the filter or the filter material.
- a preferred embodiment provides that the filter or the filter material forms the positive pole of an electric field. This will be convenient achieved in that there is a direct current source, the positive pole with the filter material and its negative pole with the carrier carrying the filter connected is.
- the filter material does not have to be completely electrical conductive material. It is sufficient if the filter material with a electrically conductive material, such as metallic wires, etc.
- the invention is based on the idea that about 80% of the bacteria are negative are charged or carry a negative partial charge on the outside.
- the counter includes a counter body 1 in which a counter trough 2 is inserted is.
- a shelf 3 is arranged on the Goods 4 lie on.
- an air flow 7 is generated in the fan 6 arranged in the counter pan, led over the goods support 3 or the goods 4 located thereon is.
- Via a drop chute 9 arranged on the customer side 8 the Air flow into the tub area below the shelf 10 and from there via an operator-side access shaft 11 and via a Exit opening 14 back into the goods area 12.
- a cooling device 13 is arranged in the flow direction in front of the fan.
- the Outlet opening 14 is completely covered by a filter 15.
- the filter is in an approximately box-shaped carrier 16 is arranged.
- the carrier 16 is on the negative Pole, the filter 15, however, is on the positive pole of a DC voltage source (not shown) connected.
- Negatively charged particles contained in the air flow in particular bacteria with a negative charge are from the positively charged material of the filter attracted and restrained due to electrical attraction.
- a Counter according to the invention is therefore overall improved hygiene, since even smallest bacteria are filtered out of the air flow.
- Convention Filtering would only be possible through a very small pore size of the filter material to reach.
- Such a filter would, however, greatly affect the circulated air flow oppose high resistance.
- the pore size are therefore reduced technical limits.
- a filter of the type described above is preferred designed as a reusable filter and detachable on a frame or Carrier attached. The filter can, for example, at predetermined maintenance intervals by washing at an elevated temperature and adding Cleaning agents are sterilized and reused.
- the filter in one example arranged magnetic field generated by a permanent magnet is, the field z. B. is directed so that negatively charged particles across Flow direction are deflected. Electrically negatively charged particles would thus in the area close to the positive pole of the magnetic field or in accumulate the area of the filter located there.
