Definitions

  • the invention relates to a cooling tunnel, comprising a treatment room separated from the outside environment, an introducer sheath for introducing objects to be cooled into the treatment room, a discharge sheath for discharging objects from the treatment room, a plurality of successive treatment positions within the treatment room for supplying them cooling articles with a cooling medium, in particular cooling air, and a conveying device for transporting the objects to be cooled from the introducer to the exit lock, wherein the conveyor passes through the individual treatment positions and has a first portion passing through several treatment positions extending from the introducer sheath to a reversal position extends, and a plurality of treatment positions passing through the second section, which extends from the reversing position to the discharge lock. Furthermore, the invention relates to a method for operating a cooling tunnel according to the preamble of claim 12.
  • a cooling tunnel according to the preamble of claim 1 and a corresponding operating method according to the preamble of claim 12 are known from FR 2 793 006 A1 known. More cooling tunnels are out of the US 2,474,069 A and the DE 100 17 408 A1 known.
  • the objects to be cooled for example milk products stacked on pallets, are conveyed continuously from the treatment position to the treatment position in the known cooling tunnels by means of a conveyor and are cooled by lateral injection of cooling air.
  • Continuous cooling tunnels are therefore economical only for purposes in which the desired cooling times of the individual objects do not vary too much. For larger throughputs, some optimization can be achieved by parallel operation of multiple conveyors in a cooling tunnel.
  • the invention has the object to provide a cooling tunnel that allows for variable target cooling times a high throughput.
  • the cooling tunnel according to claim 1 is characterized in particular by the fact that the conveying device has a return section which is arranged inside the treatment space in front of the discharge lock and connects a delivery-side area of the second section to an insertion-side area of the first section in order to selectively discharge or further cool objects.
  • the conveyor allows with the first and second sections and the return section a circulation for the objects to be cooled, with the return section in front of the discharge lock a switch is provided, which makes it possible to coincideschleusen sufficiently cooled items, but not enough cooled items to continue to cool ,
  • the conveyor can be controlled so that a feed is only made if it is necessary for discharging finished-cooled objects or to change the treatment position.
  • the first and second sections of the conveyor are arranged side by side in the common treatment space, wherein outflow areas for supplying cooling medium to the individual treatment positions on opposite side walls of the Treatment room are located.
  • This allows a compact design and efficient use of the cooling medium.
  • it is not necessary to rotate the objects to be cooled for the purpose of applying cooling medium from opposite sides about their vertical axis. Elaborate turntables on the conveyor can thus be omitted. Also adjacent portions with opposite directions of blowing, which would lead to flow losses or require delimitations with each other avoided.
  • an air outlet between the first and second sections of the conveyor, whereby a good air flow to the objects to be cooled and thus a high cooling effect is achieved.
  • the second section of the conveying device can connect directly to the first section of the conveying device at the reversing position, it being possible for means to be provided in order to maintain the original orientation of the objects to be cooled.
  • a transfer device for transferring objects from the first section of the conveyor to the second section of the conveyor is arranged at the reversing position, whereby a parallel arrangement of the first and second sections is made possible with a small distance. The footprint of the cooling tunnel remains so low.
  • first portion and the second portion of the conveyor may have separately drivable portions, wherein at the end of each portion of the first portion, a transfer device for transferring objects to the second portion is arranged.
  • a transfer device for transferring objects to the second portion is arranged at the end of each portion of the first portion.
  • Separately controllable outflow regions for supplying cooling medium are preferably assigned to the subregions. This allows the cooling tunnel to be adapted to varying throughput quantities. For example, with low throughputs Partial areas are switched off and accordingly energy is saved. This is further promoted by arranging the sections in separate treatment rooms, which are separated from each other by bulkheads. Furthermore, it is possible to realize different cooling processes by means of an air technology separate for the subregions.
  • the first section of the conveyor at least in a subsequent to the introducer sheath portion for each treatment position on an individually controllable single-user drive.
  • the objects to be cooled can be dammed up in this area.
  • a further promotion takes place only if necessary. This can reduce the number of product movements.
  • the energy efficiency can thus be optimized in particular in the case of a cooling tunnel consisting of several partial areas with low throughput quantities by superfluous partial areas being switched off by concentrating on the one or more partial areas.
  • the cooling tunnel according to the invention preferably further comprises a control device for controlling the individual sections of the conveyor as well as possibly existing section sections.
  • the control device is configured such that a time account for the required target cooling time is assigned to each item introduced. Based on the cooling time account and the operation of the conveyor, the position of each item can be determined. If it is determined in the control device that an object is located in front of the return section, it is checked whether its cooling time account has expired. If this is the case, the object in question is ejected by operating the second section. Otherwise, the article is transferred to the first section of the conveyor by operation of the return section. As a result, a fully automatic operation of the cooling tunnel can be realized.
  • control device In the presence of a plurality of reversing positions can be further determined via the control device, whether for a particular object of the conveying path should be abbreviated.
  • the control device transmits a corresponding signal to the relevant transfer device.
  • a decision logic suitable for this purpose is stored, with which it is checked whether the object is to be transferred to the second section or to stay in the first section.
  • the invention further provides a method for operating a cooling tunnel according to claim 12, which is particularly suitable for the operation of the above-described cooling tunnel.
  • the method according to the invention relates to a cooling tunnel with a circulation conveyor running through successive treatment positions, as well as an introducer sheath and a discharge sheath.
  • objects with different desired cooling times are subsequently transferred to the circulation conveyor via the introducer sheath.
  • Each item is assigned a time account with a target cooling time, on which the accumulated dwell time in the cooling tunnel is recorded. If an item reaches a position in front of the exit lock, the cooling time account is used to decide whether the item is to be dispensed through the exit lock or remains on the circulating conveyor. Expires the target cooling time while staying in the cooling tunnel, an execution of the subject matter is caused, with possibly upstream objects for which the target cooling time has not expired, are passed by the exit lock.
  • the dwell times for different feed directions of cooling medium are recorded separately on the cooling time account. As a result, a more uniform cooling can be achieved.
  • the method according to the invention can be modified in such a way that it is decided on the basis of the cooling time account of several objects whether an article passes through the abbreviation branch or not.
  • articles with a shorter target cooling time can be passed through the cooling tunnel more quickly, while at least a portion of the articles with higher residual cooling times need not be moved or at least less frequently.
  • cooling tunnel 1 for cooling objects 10 such as dairy products and the like by means of a cooling medium.
  • the articles 10 are stacked on pallets 11, which are flowed at different treatment positions within the cooling tunnel 1 with cooling air.

However, this does not automatically mean that each article 10 to be cooled must remain at each treatment position 21.1 to 21.8 for an equal time interval. Rather, the feed of the conveyor 30 can be adjusted flexibly, so that different residence times result for the objects 10 at individual treatment positions, as will be explained in more detail below.
  • the conveyor 30 has first section 31 and a second section 32, which are delimited by a reversing position 33 against each other. Each section passes through multiple treatment positions 21.1 to 21.4 and 21.5 to 21.8. While the first section 31 extends from the introducer sheath 23 to the reversing position 33, the second section 32 extends from the reversing position 33 to the discharge lock 24. Both sections are arranged parallel to each other in the illustrated embodiment, but have opposite conveying directions, so that the Introductory lock 23 and the exit lock 24 are adjacent. At the in Fig. 1b In the variant shown, the introducer sheath 23 and the discharge sheath 24 are arranged at opposite ends of the cooling tunnel 1. Due to the circulation conveying principle of the conveyor 30, the arrangement of the locks 23 and 24, however, for example, also be done on the corner. In addition, more than a total of two locks 23 and 24 can be provided if necessary.
  • the conveyor 30 has a return section 34. This is arranged immediately in front of the discharge lock 24 and after the last treatment position 21.8 of the second section 32 and, if required, allows a transfer of articles 10 from the second section 32 to the first section 31. As a result, articles 10 can optionally be discharged or further cooled.
  • the section can be designed, for example, as a driven roller conveyor with raisable and lowerable rollers, so that, depending on its position, an object transported on the second section 32 is picked up and branched off to the first section 31 or transported on to the discharge lock 24.
