Definitions

  • the invention relates to a drying oven referred to in the preamble of claim 1 Art.
  • drying cabinets are used, for example, to dry pharmaceutical or chemical products or foods such as milk, proteins, soups, fruits, vegetables and the like. In many cases, the drying takes place under vacuum, which is why the drying cabinets are designed accordingly.
  • a drying cabinet referred to in the preamble of claim 1 is known from DE-C1-198 08 408 known. Its upper wall has a vacuum-tight closable pipe socket, through which a cleaning device in the interior of the drying cabinet can be inserted. This powered by a motor cleaning device has nozzles through which cleaning fluid can be sprayed into the individual floors of the drying cabinet. From the nozzle, the jet of detergent comes out horizontally. The fact that the nozzle is horizontally pivotable, the corners of the interior of the drying cabinet can be achieved by the beam.
  • a drying cabinet which is equipped with a stationary cleaning device.
  • On both sides of the trays arranged tubes have a plurality of nozzles through which the detergent can be sprayed onto the individual trays.
  • an oven which has a device for supplying relaxed wet steam.
  • a flushing device is provided, with the wash liquor can be introduced through spray nozzles in the baking chamber.
  • US-A-4,732,172 is known a washing device for movable cars, from EP-A2-1 055 462 a device for cleaning germ strains.
  • EP-A2-1 055 462 a device for cleaning germ strains.
  • off US-A-6,158,146 a drying device known.
  • the invention has for its object to provide a drying cabinet with a cleaning device, the cleaning effect over the prior art is further improved.
  • a drying cabinet in its entirety. This consists of a housing cube 2 open on one side, which can be closed on the open side with a door 3. If the drying cabinet 1 is to be designed as a vacuum drying cabinet, then a seal, not shown here, is attached to the door 3.
  • the interior of the drying cabinet 1 is designated by the reference numeral 4. This interior 4 is subdivided by shelves 5 designed as trays, onto which product trays 6 can be placed. These product trays 6 are removable. They can thus be cleaned outside the drying cabinet 1 in a particularly effective manner. Shown is only one of the product trays 6 on the top of the heating plates 5. During the cleaning work for the drying oven 1 all product trays 6 are taken out of the oven 1, which is why the one product tray 6 only dashed lines to show their position. Also, the bottom of the - drying cabinet 1 may contain a heating plate 5.
  • a cleaning device 10 is inserted into the interior 4 of the drying cabinet 1. This is either stationary arranged in the drying oven 1 or can be used in an advantageous manner in the drying oven 1 and also removed again. This will be shown in detail. If the cleaning device 10 is removable, it can be used successively for a plurality of drying cabinets 1. This saves investment funds, because for a larger number of drying cabinets, only a single cleaning device 10 must be procured.
  • the cleaning device 10 consists of a carrier 11 to which a plurality of horizontal support arms 12 are attached.
  • the number of support arms 12 is as large as the number of spaces between the ceiling of the interior 4, the heating plates 5 and the bottom of the interior 4 of the drying cabinet 1.
  • a spray arm 13 is easily rotatably disposed around the vertical axis A rotates.
  • Each spray arm 13 is equipped with a number of nozzles 14. These nozzles 14 are in a known manner such that the liquid jet emerges obliquely to the longitudinal axis of the spray arm 13, thereby causing the spray arm 13 is caused to rotate about the axis A by the recoil of the spray.
  • a motor drive of the spray arms 13 can be omitted.
  • the carrier 11 has in its interior a channel 15 through which the cleaning medium reaches the support arms 12 and from there it passes through cavities 16 in the support arms 12 to the spray arms thirteenth
  • the carrier 11 is supported in the embodiment shown on the inner bottom of the drying cabinet 1 from. It can be fixed there or simply rest, so that it is removable. Other solutions are possible in the context of the invention, such as the support on one of the heating plates 5, for example, the top, or the support in guide rails on the two side walls of the interior 4 of the drying cabinet. 1
  • the carrier 11 has an opening 20 through which the cleaning medium can enter the channel 15.
  • the so supplied cleaning medium then passes through the channel 15 to the cavities 16 of the individual support arms 12 and from there into the Interior of the individual spray arms 13, through whose nozzles 14 it can be sprayed into the interior 4 of the drying cabinet 1.
  • DE-C1-198 08 408 known closable hole in the bottom of the drying cabinet 1, through which the cleaning medium can flow.
  • Fig. 2 is a horizontal section through the drying cabinet 1 with a top view of the cleaning device 10 is shown. Shown here is also a plan view of a support arm 12 connected to the carrier 11 and a thereto about the axis A rotatably mounted spray arm 13.
  • the spray arm 13 has nozzles 14. At one of the legs of the spray arm 13, the nozzles 14 are on the top so that they are in the Fig. 2 are drawn with solid lines, while they are arranged on the other leg on the bottom and are therefore shown with dashed lines.
  • the rotation of the spray arm 13 about the axis A is shown by an arrow.
  • a spray arm 13 is shown with its nozzles 14.
  • a flow channel 24 can be seen, which is in communication with the cavity 16 of the support arm 12. The cleaning agent can thus flow from the cavity 16 into the flow channel 24 and then through the individual nozzles 14 into the interior 4 (FIG. Fig. 1 ) of the drying cabinet 1.
  • approximately horizontally radiating nozzles 14 are present on the spray arm 13 at its radial ends, which serves for optimal distribution of the cleaning agent in the interior 4. This purpose is also served by a further nozzle 14 in the middle part 25 of the spray arm 13.
  • the optimum distribution of the cleaning agent is used also the measure that the two legs of the spray arm 13 are arranged offset in height. That leg with upwardly radiating nozzles 14 is arranged further down, while the leg is arranged with downwardly radiating nozzles 14 higher up.
  • the drying cabinet 1 is shown with the door 3 not shown here, and a device for transporting the cleaning device 10.
  • Dry barrier 1 for the chemical, pharmaceutical and food industries can certainly have considerable dimensions, for example about 2 x 2 x 2 m. Accordingly, the dimensions of the cleaning device 10 are corresponding, and this also results in a considerable weight.
  • a transport device 40 is advantageous. This is by means of wheels 41 on the surface 42 on which the drying cabinet 1 is movable.
  • the transport device 40 has coupling means 43, by means of which the cleaning device 10 can be frictionally connected to the transport device 40.
  • the Fig. 1 and 2 let recognize that it is not possible because of the shape of the cleaning device 10 to remove the product trays 6 from the drying oven 1 or to use in this, when the cleaning device 10 is inserted into the drying oven 1. However, this is true only if the product trays 6 are so large that they correspond approximately to the width and depth of the heating plates 5. For smaller product trays 6, this problem does not occur. So before the drying cabinet 1 can be loaded or unloaded when using such a large product trays 6, the cleaning device 10 must be taken out of the oven 1.
  • the transport device 40 is also used when a cleaning device 10 is to be used successively for a plurality of drying cabinets 1, as has been mentioned in the introduction.
  • the Fig. 4 also shows in contrast to the Fig. 1 and 2 a differently placed connection of the cleaning device 10 for supplying the cleaning medium.
  • the pipe duct 22 is arranged here in the rear wall of the drying cabinet 1 and the opening 20 is located at one of the pipe feedthrough 22 facing end side of the Carrier 11.
  • the opening 20 and the pipe duct 22 may be designed as a quick coupling, so that when retracting the cleaning device 10 in the drying oven 1 automatically the cleaning device 10 is coupled to a line for the cleaning medium.
  • the cleaning device 10 is to be an integral part of the drying cabinet 1, that is to say not designed to be removable, then the carrier 11 is advantageously to be designed so that it does not obstruct the insertion and removal of large product trays 6.
  • Such an advantageous embodiment shows the Fig. 5 ,
  • the carrier 11 is arranged in one of the corners of the drying cabinet 1.
  • the carrier arms 11 attached to the support arms 12 are pivotable.
  • the carrier 11 with its rigidly attached support arms 12 can be rotatable about its own axis or the support arms 12 about the carrier 11 pivotally.
  • Fig. 5 is shown with solid lines, the rest position of the support arms 12 with the attached spray arm 13, with dashed lines that position, which is taken during the execution of the cleaning.
  • the support arm 12 projects obliquely into the interior 4 of the drying cabinet 1 to the center.
  • a variant of a spray arm 13 is shown in a schematic plan view.
  • the present at the radial ends of the spray arm 13 nozzles 14 do not spray in the radial direction, but significantly oblique to the longitudinal axis of the spray arm 13, resulting in the force resulting from the recoil of the spray jet force for the rotation of the spray arm 13 about its axis of rotation A.
