  • Blower unit and method for cooling or warming up
  • the invention relates to a blower unit, in particular for foods such as meat, meat and / or sausages, according to the preamble of claim 1 and a method for cooling or heating.
  • E-2 boxes are becoming increasingly important as a means of transport for meat or meat products. These are standardized boxes with a length x width x height ratio of 600 x 400 x 200 mm. Meat coming from the slaughterhouse is temporarily stored in these boxes in order to be transported to the further processor. In addition, more and more companies are taking advantage of these boxes for in-house transport or for internal storage.
  • Blower units are also known in cold stores in order to circulate the cooling air. The problems can hardly be reduced by this.
  • the blower unit according to the invention is characterized in that it is precisely matched to one or more of the food crates used. Since, as mentioned, preferably so-called E-2 boxes for the storage and transport of meat products have gained in importance, the fan unit according to the invention can be matched or adapted to such boxes with regard to the dimensions used.
  • blower unit can have a construction which will be discussed in detail below, e.g.
  • An embodiment is preferably used in which the blower unit according to the invention is matched to two or, for example, four corresponding food crates in the base area, to an individual E-2 crate or to another Emzel crate having a different standardization or size. It is also preferably provided that the fan unit according to the invention is matched to an arrangement in which a plurality of boxes are stacked on top of one another, for example eight layers.
  • the construction according to the invention ensures that the blower unit is designed or is provided with an adapter device in such a way that an air flow is generated by a single or possibly a plurality of blower units, which air flow is forcibly passed through the holes provided in the stackable boxes becomes.
  • the blower unit according to the invention is designed in such a way that it receives the one or more stackable boxes or is arranged opposite them in such a way that the air flow generated via the one or more blower units is forced through the wall openings Boxes is guided and can thereby contribute to an optimal cooling or warming up process.
  • the blower unit according to the invention is constructed in such a way that it is attached existing disadvantage is turned to an advantage. Because the small-sized openings and the appropriately adapted blower unit can ensure that a certain overpressure is generated between the blower unit and the first adjacent stackable food boxes. The resulting stowage area distributes the air flow evenly over all boxes, so that the air flow must flow through the opening through the boxes.
  • the invention can also be used when boxes are used which have no opening or air openings in the side walls. Because there are also boxes with closed side walls, which, however, have stacked bottoms, in such a way that when stacking two boxes between the stacking boxes, or bottom edge of the upper box and the peripheral edge of the lower box form louvers through which the cooling air can then be blown or sucked.
  • the blower unit is preferably constructed such that it can be moved. It is also preferably provided that, in addition to the actual housing unit for receiving the one or more blower units, it is only provided with lateral walls forming an air duct, which - if the device is no longer required - preferably also preferably at least in a partial length laterally on top of one another can be pivoted.
  • the side panels When the side panels are open, the device can be closed on several stackable boxes in such a way that the side walls encompass the boxes stacked on top of one another and close a side airway, so that the air flowing around can only flow through the air openings in the boxes. If necessary, a cover plate can be placed on the top box so that cooling or warming air cannot flow out through the top stackable boxes comparatively ineffectively.
  • a time and temperature control is preferably also provided in order to ensure controlled cooling or heating.
  • the blower units according to the invention can be equipped with one or more batteries or accumulators. However, they can also be provided with a mains connection. An apprenticeship as a tional cold room units are possible.
  • blower unit As a unit with a refrigerator-like combination, so that the blower unit also generates cooling air which is blown through the food crates. This means that the device can also be set up and used outside of cold rooms.
  • the blower units according to the invention contribute to a significant improvement in food processing, since this enables the best possible and fastest cooling of meat and, if necessary, comparatively rapid heating or thawing of frozen meat.
  • meat - as is common today - can be cut up at approx. 4 "C, whereby the meat heats up to about 6'C during the cutting process, in order to then put it into the containers or boxes mentioned above then, together with the fan unit according to the invention, can be rapidly cooled to, for example, -1.2'C shortly before the crystallization point or more.
  • the device according to the invention can also be operated in such a way that the blower device is operated in the opposite direction, that is to say air can flow outward.
  • the blower device is operated in the opposite direction, that is to say air can flow outward.
  • the blower unit can be used for rapid cooling or heating, thawing or freezing, whereby the unit does not have to cool itself, but can be parked in a refrigerator if required. In the same way, however, it can be expanded and equipped with a refrigerator-like cooling device.
  • the cooling unit can be coordinated so that, for example, four crates on one level and eight levels are stacked on a Euro pallet, all of which can be cooled at the same time.
  • the close-fitting side walls create an even air flow that flows through all the boxes and cools the entire range at maximum speed.
  • the blower device builds up a pressure or underpressure, which accelerates the desired forced ventilation for the cooling or warming-up process very strongly.
  • Safe cooling without freeze damage can be achieved through an adjustable fan runtime and / or adjustable break times, as well as through provided digital thermometers in the meat core and at peripheral areas become. It is also possible, for example, to thaw to -3 "C without reaching a surface temperature of over -1.2'C (since the meat is still frozen at this temperature but can already be processed).
  • the fan running time and downtime can be set independently of each other; and -
  • the total space requirement can be kept extremely low, whereby basic dimensions of 150 cm to 90 cm in the operating state and in the collapsed state from 80 cm to 90 cm are possible.
