Definitions

  • the invention relates to a cold store for storing goods at a temperature lower than the ambient temperature, in particular for the temporary cold storage of food.
  • Cold stores with large cold rooms of the type described above are used as distribution centers for chilled food for short-term storage and preparation of goods.
  • the delivered goods are cooled down in order to delay the biochemical conversions and the growth of microorganisms to an ideal cooling temperature for the respective food, the relative humidity being adapted accordingly to the goods to be cooled so that drying out or spoilage of the goods is prevented.
  • the goods are put together individually according to the corresponding orders from the individual grocery stores, food product manufacturers or processing plants and delivered to the customers by refrigerated trucks.
  • the cold store In known cold stores, the cold store is divided into individual rooms by means of fixed partition walls, each of which has an optimal temperature and air humidity for the goods to be stored.
  • This fixed subdivision of the cold store into individual cold stores has the disadvantage that the cold store must be designed from the start for a certain storage capacity for the respective goods, since subsequent enlargement or reduction of the respective cold store is not possible without expensive conversions.
  • long storage and Preservation time i.e. in transit warehouses in which the refrigerated goods are stored and prepared for goods preparation
  • rigid dividing and insulating walls is unfavorable for a profitable workflow. It cannot be predicted which goods will need to be temporarily stored in which quantities.
  • the cold stores sectioned off by rigid walls do not permit rapid retrofitting of storage racks and access routes for forklift trucks and the like, since the arrangement of door openings and the associated air locks is predetermined.
  • the invention is therefore based on the issue of creating a cold store of the type mentioned at the outset, in which the individual temperature and humidity ranges can be adapted to the respective storage capacity of the individual foods, and which enables a simple redesign of the storage devices, so that the workflow is profitable .
  • a cold store which essentially has a single cold store or a single large cold store, in which the individual storage devices such as racks or the like are arranged for receiving the goods to be cooled.
  • the large cold room is subdivided into individual temperature zones with the aid of controllable separating devices, zones being arranged next to one another with increasing temperature, so that there is an essentially continuous temperature gradient from one cold store wall to the opposite cold store wall.
  • Both Separation devices can be refrigerators that are arranged on supporting frames in the ceiling area of the large cold storage room and generate cold air that either falls down automatically due to gravity and thus delimits the zone around the ceiling cooler or is distributed by air circulation fans.
  • a central cooling generator can be provided which is connected to air guiding devices which ensure that adjacent cooling zones are separated from one another by cold air curtains.
  • the system according to the invention gives the user the possibility of adapting and increasing or reducing the storage volume to the respective conditions by spreading out in a previously delimited zone and adapting the respective newly created zone to the corresponding temperature conditions individually.
  • the temperature zone is delimited by the cold air itself, which emerges from the ceiling cooling units, whereby a natural air curtain is created by the slow sinking of the cold air. This air curtain can be penetrated at any point by the cold store personnel or forklift vehicles, so that the arrangement of the stacking devices is also variable according to the temperature zones.
  • the order of the temperature and humidity zones can be changed as desired, since the ceiling cooling system is designed so that each temperature zone can be controlled individually.
  • the large cold room 2 shown in FIG. 1 of the cold store 1 provided with the loading ramps 3 and 4 serves for the storage of food or other products to be cooled under approximately ideal temperature and humidity conditions.
  • the large cold room is not divided by walls, as was previously the case. Rather, several refrigerators 6 are arranged on the ceiling 5, the distances from one another being chosen such that the laterally emerging cold air curtains overlap one another, so that each of the five zones I to V shown in the drawing is separated by cold air curtains.
  • the cold air emerging from the cooling generators 6 forms a natural air curtain during the slow sinking.
  • zone I on the left in the figure has a temperature level of 0 ° C.
  • zone II on the right in the figure has a temperature level of + 4 ° C.
  • a mixing zone results, the temperature value of which corresponds to the mean value between the temperatures of the core zones of the two adjacent zones, in this case +2 ° C.
  • the refrigeration devices 6 are connected to one another by line systems and can be controlled individually, so that each zone can be operated in a different temperature range.
  • zone I can be merged with zone II by appropriately controlling the zone II refrigerators at 0 ° C, so that the zones are individually connected to the Storage requirements are customizable.
  • the order of the zones can be changed accordingly, although care must be taken to ensure that the temperature differences between the zones are kept as small as possible.
  • Ceiling cooling units that contain either static cooling elements, that is, heat exchangers without dynamic air charging by additional fans, are used as refrigerators, so that the cold air generated by these cooling elements automatically falls down by natural gravity and thus causes a corresponding delimitation of the respective temperature zone.
  • a refrigeration medium of -7 C is generated, for example.
  • This refrigerant which can be formed, for example, by a gaseous or liquid refrigerant, is fed via a pipeline 8 to a distribution channel 9.
  • the supply lines 10 of the refrigeration devices 6 of the individual temperature zones connect to this distribution channel 9. While the upper feed line 10 in the drawing is connected directly to a refrigeration generator 6, a feed chamber 10a is connected to a mixing chamber 11 into which the flow line 12 and the return line 13 open.
  • the flow line 12 is in turn connected to a distribution channel 14 to which the individual refrigeration devices 6 are connected.
  • a pump 15 is provided in the return line 13.
  • the return line 16 is also connected to the mixing chamber 11, said return line being connected to the collecting duct 17, into which the return line 18 with the pump 19 arranged therein opens.
  • the return line 18 is connected to the refrigeration center 7.
  • three-way valves 20 and 21 are provided in the pipes 8 and 10a, which establish a connection to the return lines 18 and 16 via the lines 22 and 23, respectively.
  • Temperature sensors 24 and 25 monitor the inlet temperature into the distribution channels 9 and 14, respectively, and ensure that the three-way valves 20 and 21 are controlled accordingly.
  • the refrigeration center 7 generates a uniform temperature level in the refrigeration medium, which can be air, for example, of -7 ° C.
  • This cooling medium can be used to cool down the temperature in zone I immediately.
  • the cooling medium can be passed into a mixing chamber 11, where mixing with the warmed up cooling medium supplied via the ' return line 13 takes place until the desired temperature level, for example -5 ° C., in the supply line 12 is reached.
  • the cooling medium cooled down to -5 ° C. can then be fed to the cooling generators 6 of zone II. Accordingly, the temperature generation in zones III to V is achieved.
  • the individual refrigeration production per zone enables individual regulation of the flow temperature.
  • a central cooling generator Refrigeration medium with constant flow temperature is generated, which corresponds to the flow temperature of the coldest zone.
  • a temperature adjustment can take place fully automatically using suitable temperature valves through heat exchangers or mixing tanks. Maintaining the constant flow temperature for the refrigerators in the different zones can be controlled fully automatically by valves installed in the refrigeration circuit.
  • defrosting devices In order to be able to defrost the refrigeration devices after icing, known defrosting devices are provided which are effective at certain time intervals. These defrosting devices can, for example, be supplied with circulating air as a heat carrier or have built-in heating systems.
  • Air humidifiers can also be arranged between or next to the refrigerators, in particular in the areas in which fresh vegetables are stored. It is also conceivable that the cooling generators and humidifiers are movably mounted on rails so that they can be moved along the ceiling 5 of the large cooling room 2 or can be lowered under certain circumstances in order to individually reduce or design the space delimited by the cold air curtain .
