Definitions

  • ABSTRACT 0F THE DISCLOSURE Cooling apparatus for cooling bottled liquids and the like comprising a source of pressurized gas, a gas-permeable receptacle for the object to be cooled, a spray nozzle communicating with the interior of the receptacle and with the source of pressurized gas and valve means for regulating the flow of gas between the gas source and the receptacle.
  • the present invention relates to an apparatus for cooling objects or substances, particularly bottled liquids.
  • the invention relates to apparatus for quickly and etiiciently cooling substances, for example beverages, by means of expanding gases.
  • a particularly preferred gas for use in this apparatus is carbon dioxide (CO2).
  • a source of CO2 under pressure is connected by at least one pipe to a cooling station comprising one or more means for distributing CO2 or other suitable gas and containers to hold and enclose the objects or substances to be cooled during the delivery of cooling medium.
  • the means for distributing the CO2 are cocks connected in parallel to the supply pipe, and the containers are composed of fabric bags secured to the respective nozzles of the cocks or movable baskets disposed beneath the nozzles during the cooling phase.
  • the CO2 distribution means comprises a portable gun device connected to the CO2 pipe or source by means of a flexible p1pe.
  • the single ligure is a schematic view of one embodiment of the cooling apparatus of lthe present invention.
  • the source of carbon dioxide (CO2) is a cylinder 1 containing the gas under suitable pressure and provided with delivery and control devices, such as a discharge valve 2 and a pressure gauge 3.
  • a two-way valve 4 is interposed between the gauge and the cylinder 1.
  • a conduit 5, preferably a copper pipe, conducts the cornpressed gas from the cylinder to the cooling station 6. Flow of gas from the cylinder 1 to the conduit 5 is controlled by the valve 2.
  • the cooling station 6 is preferably disposed at a distance from the cylinder 1 and comprises a lixed bench 7 which serves as a support for CO2 distribution means R1, R2, R3 and R4 and for cooling containers C1, C2, C3 and C4.
  • the CO2 distributor means comprises four cocks or valve means R1, R2, R3
  • cocks connected in parallel to the end 5 of the supply pipe 5.
  • any number of cocks could be used, depending upon the needs of the user.
  • an atomizing nozzle r1, r2, r3 and r4 which has a small outlet hole through which the jet of CO2 is sprayed into the containers C1, C2, C3 4and C., to effect the desired cooling.
  • the cocks may in addition be provided with ilow indicators P1, P2, P3 and P4, which indicate the amount of CO2 delivered. It is thus possible to adjust the cocks to adapt the CO2 ow to the requirements for the particular object to be cooled and to avoid possible damage which might be caused by too violent a jet of CO2.
  • the containers C1, C2, C3 and C4 are adapted to receive the objects to be cooled, which may be, for example, bottles containing liquid.
  • these containers C1, C2, C3 and C4 are bags which are secured to their respective nozzles r1, r2, r3 and T4.
  • These bags may be of cloth, e.g., wool, or of any suitable fabric or material capable of withstanding the violence of the jet of CO2 during the cooling stage and at the same time capable of permitting the slow passage therethrough of the expanded CO2.
  • the container encloses the bottle in such a manner that the flow of cooling CO2 surrounds the bottle and then slowly passes out of the container.
  • Each bag is provided with an opening for the insertion and withdrawal of the bottle, this opening being closed before operating the cock for delivering CO2. In the drawing these openings are at the sides of the bags and are controlled by sliding clasp fasteners 8, 9, 10 and 11.
  • the containers C1, C2, C3 and C4 are in the form of baskets or buckets supported on the bottom of the bench 7 and placed beneath the nozzle during cooling.
  • the cock assembly may be replaced by portable gun devices, in which case the connection to the conduit 5 or the entire connection to the cylinder 1 may be by means of ⁇ a flexible pipe.
  • the source of CO2 may comprise a plurality of cylinders, preferably disposed in parallel, and each provided with delivery and control devices as illustrated for the cylinder 1.
  • the cooling station distribution means may comprise a mixture of cocks Iand gun devices.
  • the cooling operation is extremely simple and takes a few moments.
  • a bottle containing, eg., a beverage is' placed in the bag or bucket ⁇ beneath the nozzle, the cock is opened and the bottle bathed by the expanded, cooled gas.
  • the expansion of CO2 produces an extremely cold spray which almost instantaneously cools the bottle.
  • the cock is then closed and the cooled bottle then removed from the container, ready for consumption of the beverage.
  • Cooling apparatus comprising a source of pressurized gas, a gas-permeable receptacle, a spray nozzle cornmunicating with the interior of said receptacle, a conduit communicating said gas source with said spray nozzle and a valve means for regulating the flow of gas between said gas source and said receptacle, said receptacle being a bag of material permeable to the flow of said gas and4 having a closeable opening therein for introducing an object to be cooled into said receptacle and for removing a cooled object therefrom.
