Definitions

  • the invention relates to a filling device for filling a refrigerant receiving compartment associated with a cooling container for cooling products with a cryogenic refrigerant, with a supply device equipped with a decompression nozzle for supplying the cryogenic refrigerant in the liquid state, a discharge device opening out at a discharge opening for discharging during the filling process vaporized cryogenic refrigerant and a retainer, by means of which the non-evaporated at the time of filling cryogenic refrigerant is retained at least predominantly in the refrigerant receiving compartment.
  • Such a device is from the US-A-5,657,642 known.
  • isothermal cooling containers For transporting heat-sensitive products, in particular food, such as fresh or frozen products, isothermal cooling containers are used, with which a complete cold chain from production to the end customer should be ensured even if a permanent cooling by an electrically operated cooling unit not possible is.
  • Such cooling containers have a product receiving compartment for the storage of the products to be cooled and a spatially separated from this, but with this thermally connected refrigerant receiving compartment for a cryogenic refrigerant.
  • a filling gun the receiving compartment with the cryogenic refrigerant, such as dry ice, filled.
  • the filling takes place by taking advantage of the Joule-Thomson effect in that a liquefied under pressure cryogenic refrigerant is introduced, relaxed in the supply to the refrigerant receiving compartment to form cold gas and snow and the snow remains as a cold storage in the refrigerant receiving compartment ,
  • the refrigerant storage compartment is thermally connected to the product storage compartment and absorbs heat therefrom, resulting in the gradual sublimation of the snow.
  • Such a container is used for example in the EP 0 942 244 A1 described.
  • the container has a drawer-like receptacle for dry ice, which is thermally and fluidically connected to a product receiving compartment arranged thereunder.
  • the refrigerant receiving compartment is charged with liquid carbon dioxide, which relaxes when entering under strong cooling and passes into a mixture ofniceisteilchen with a temperature of -78 ° C and also cold carbon dioxide gas. Due to a corresponding adjustment of the heat transfer to the storage area, the products can be reliably maintained at a temperature of, for example, 0 ° C to 5 ° C (for fresh produce) or -15 ° C to -25 ° C (frozen) for more than 24 hours.
  • the refrigerant receiving compartment of the in EP 0 942 244 A1 described container with a in the EP 1 088 191 B1 connected filling device Refrigerant receiving compartment and filling device have corresponding to each other connection fittings, which allow an at least substantially gas-tight connection and ensure that escapes during the filling as possible, no carbon dioxide in the environment of the container.
  • the container has a feed opening and a discharge opening spaced therefrom, which can be connected to the corresponding feed and discharge connections of the filling device. Suitable security systems ensure that a filling is only possible if both the supply line and the discharge device of the filling device is connected in a substantially gas-tight manner to the receiving compartment.
  • a very similar built-up cooling tank is in the WO 2007/036656 A1 described.
  • this cooling container has a separable from the container receptacle for a cryogenic refrigerant and a separate from this by a thermal barrier storage area.
  • the supply of the cryogenic refrigerant and the discharge of the refrigerant evaporating during the filling takes place in this article by means of lateral openings, by means of which a particularly good distribution of the cryogenic refrigerant in the receiving compartment should take place.
  • a filling gun is used; for sucking off the resulting gas, the discharge opening is simultaneously connected to a suction device.
  • the cooling containers in question are usually sized so that they can be easily moved by means of attached to them wheels by a person.
  • Typical insulated containers have, for example, based on the European Palletenstandard base of 600 mm x 800 mm to 1200 mm x 800 mm and a height between 1000 mm and 2000 mm, with a useful volume of between 200 liters and 1500 liters. Since even a small amount of dry ice is sufficient to maintain a sufficiently low cooling temperature over a period of several hours, the receiving compartment for the refrigerant is much smaller dimensioned than the compartment for receiving the products and has for example a volume between 5 liters and 50 liters.
  • refrigerant storage compartments When filling the refrigerant storage compartments by means of carbon dioxide snow, which is generated locally by expansion of liquid carbon dioxide, such a small dimensioned refrigerant storage compartments has the problem that the carbon dioxide snow entrained at least partially by the resulting carbon dioxide gas and withdrawn together with this from the receptacle becomes.
  • the refrigerant storage compartments known from the prior art containers are equipped with dividing elements in the form of screens or filters, whose task is to retain the carbon dioxide particles in the refrigerant receiving compartment during the filling, while the gas can pass unhindered.

  • the entire facial expressions for the supply of the liquefied cryogenic refrigerant, the relaxation of the cryogenic refrigerant, the separation of the resulting in the relaxation solid before gaseous phase with retention of the solid refrigerant in the refrigerant receiving compartment and for the removal of the gaseous refrigerant in the filling head of Filling device housed can be dispensed with, on or in the coolant receiving compartment special connections for the supply or discharge of the refrigerant or complex separation devices for separating the solid to provide the gaseous refrigerant, whereby the structure of a fillable with the filling device according to the invention the cooling container can be considerably simplified.
  • the coupling of the filling head is no longer via the corresponding ports for supplying and discharging the gas, but via a single connection opening (filling opening) of the coolant receiving compartment, wherein for filling the refrigerant receiving compartment a mouthpiece against the refrigerant receiving compartment in the region of the filling opening is pressed or otherwise connected to produce the production of an at least substantially gas-tight connection with the refrigerant receiving compartment.
  • a controller ensures that the amounts of the supplied cryogenic refrigerant and the discharged gaseous refrigerant is coordinated such that due to the expansion inside the refrigerant receiving compartment no strong overpressure arises, but the excess gaseous refrigerant substantially simultaneously with the supply of the liquid Cryogenic refrigerant dissipated or sucked by a suction device.
  • the retaining device is preferably a screen or filter arrangement which spans the discharge opening of the discharge device.
  • the entire gas stream drawn off via the filling head of the evaporated cryogenic refrigerant is thus guided through the sieve or filter arrangement in the filling head.
  • the gas phase is reliably separated from the solids content of the cryogenic refrigerant; the particles are retained in the coolant holding compartment while the gas phase is withdrawn or drawn off.
  • An advantageous development of the invention provides that the expansion nozzle of the feed device is received within the discharge opening and opens out substantially in a plane defined by the discharge opening of the discharge device on the filling head.
  • a plurality of expansion nozzles accommodated within the discharge opening are also conceivable.
  • the retaining device extends over the entire discharge opening and saves only the mouth opening of the expansion nozzle or the mouth openings of the expansion nozzles.
  • the expansion nozzle (s) is thus not in the interior of the refrigerant receiving compartment during filling. In this way, the dependence of the filling system is reduced by the internal structure of the refrigerant receiving compartment and the expansion nozzle (s) is also or are better protected.
  • a preferred sealing element comprises sealing lips made of an elastic material, by means of which the filling head in the region of the filling opening is pressed onto the refrigerant receiving compartment in such a way that a substantially gas-tight connection is produced.
  • Elaborate fasteners such as screws or flanges are required in this embodiment neither the filling head nor the receiving compartment.
  • the sealing elements advantageously comprise a pneumatic or hydraulic sealing element which produces a substantially gas-tight connection with the filling opening of the refrigerant receiving compartment by filling with a gaseous or liquid medium.
  • the pneumatic or hydraulic sealing element is arranged on the outer circumference of the filling head and the filling head can be pushed into the filling opening at least with its front portion.
  • the limited increase in volume of the sealing element also allows a secure connection even if there is a certain amount of play between the filling opening and the filling head.
  • the gaseous or liquid medium can also be heated before being fed to the sealing element.
  • a particularly simple handling promises an embodiment in which the supply device is connected to a supply line to a source of liquid carbon dioxide and the discharge device is connected to a discharge line for gaseous carbon dioxide, wherein the supply line and the discharge line is at least partially made of a flexible material.
  • the flexible supply line received within the flexible discharge line.
  • the filling head is equipped with a detector for detecting a gas-tight connection with the refrigerant receiving compartment.
  • a yet again advantageous filling device is characterized in that the supply device has at least two supply lines spaced apart from each other, preferably separately controllable, each equipped with expansion nozzles or injectors.
  • the supply device has at least two supply lines spaced apart from each other, preferably separately controllable, each equipped with expansion nozzles or injectors.
  • an advantageous development of the invention provides that the refrigerant receiving compartment with subcooled cryogenic refrigerant, for example, supercooled liquid carbon dioxide is charged.
  • the feeder associated with a means for generating supercooled liquid cryogenic refrigerant is for example from the EP 1 097 343 B1 known.
  • This object is subject to subcooling of liquid carbon dioxide using a compression refrigerator.
  • the compression refrigeration machine By controlling the compression refrigeration machine, the temperature of the liquid carbon dioxide and thus the proportion of the carbon dioxide snow formed during the expansion of the liquid carbon dioxide can be adjusted precisely. By switching the mode of operation of the compression chiller, this can also be used for heating the carbon dioxide-carrying lines and, where appropriate, the associated with these refrigerant receiving compartment for the purpose of deicing.
  • the filling device according to the invention allows the use of cooling containers, which have a comparison with refrigerated containers according to the prior art greatly simplified construction.
  • a cooling container which is suitable for filling by means of a filling device according to the invention for cooling products with a cryogenic refrigerant, a refrigerant receiving compartment, and a thermally connected thereto product receiving compartment for receiving the products to be cooled, wherein the refrigerant storage compartment has a filling opening into which the filling device with its filling head can be inserted.

  • both the supply of liquid cryogenic refrigerant, in particular feeding of liquid carbon dioxide and the removal of gaseous cryogenic refrigerant can take place via the same filling opening.
  • the refrigerant receiving compartment requires neither special coupling fittings for coupling the filling device, nor a separator arranged in the refrigerant receiving compartment.

  • an advantageous embodiment of the invention provides that the refrigerant receiving compartment has a substantially cuboid or cylindrical structure, wherein the filling opening occupies at least a large part of a side surface or even almost a complete side surface of the refrigerant receiving compartment. Due to the large filling opening in comparison to filling systems according to the prior art, a particularly rapid filling can be achieved.
  • the refrigerant receiving compartment preferably has a filling opening with a round, oval or rectangular cross section which extends over a large part of a side surface of the refrigerant receiving compartment. Since the filling device according to the invention requires no special connection mimic in the form of feeds or flange connections, the filling opening can therefore extend over at least almost the entire area visible in the cooling container in the installed state of the refrigerant receiving compartment. In this way, a particularly fast filling of the refrigerant receiving compartment succeeds.
