Brief Patent Description - Full Patent Description - Patent Application Claims
OBJECT OF THE INVENTION [0001] The present invention relates to a procedure and apparatus for rapid cooling of beverages packaged in can or bottle type containers, which is based fundamentally on storing brine or another aqueous solution and chilling it to a temperature proximate to its freezing point in a reservoir receptacle and spraying it onto the packaged beverage while it rotates about its axis, for a time that is calculated from the initial and desired temperatures, the temperatures of the cold solution and of the rinsing water and of the temporal coefficient of the packaged beverage, returning the cold solution to the reservoir. [0002] An object of the invention is a procedure of deducing the temporal coefficient of the packaged beverage from the initial temperature of the beverage, the temperature of the cooling aqueous liquid and of the equilibrium temperature of the beverage and its container during a stoppage of the cooling, calculated from measuring in three successive instants the temperature developing on the surface of the container. [0003] The temporal coefficient is necessary for calculating the duration of the cooling. It depends on several factors: temporal measurement unit, design of the container, material, thickness and nature of its surfaces, beverage volume, specific heat of the same, viscosity, tangential rotational speed of the container, free gas in the container, specific heat of the cooling liquid, its viscosity and flow rate used during the cooling. [0004] It likewise constitutes an object of the invention that the rapid cooling apparatus employed has means which facilitate the rotation of the can or bottle type containers to be cooled forcing turbulence on the interior and also that it incorporates means of rinsing the container when cooled for the removal of the brine or cooling solution adhering to the surface. [0005] It is an object of the invention to establish a specific form of locating the reservoir and the type of spray for cooling over the containers. [0006] It is also an object of the invention the application of the procedures and apparatus cited for heating beverages by means of the spraying of hot water or another hot fluid on the containers in rotation. [0007] It also constitutes an object of the invention that the rapid cooling apparatus employed has means which facilitate the cooling of the containers of any type which cannot rotate as well as the freezing of foodstuffs packaged in hermetic bags. BACKGROUND OF THE INVENTION [0008] The transition point for CaCl2 dissolved in water is 0.2985 mass fraction and -54.23.degree. C. Higher concentrations crystallize part of the CaCl2 in the form of CaCl2 6(H2O) and lower concentrations freeze water to reach the equilibrium concentration. The behaviour of the solution is seen in FIG. 31. [0009] The mean specific heat of the solution is 0.669 cal/g equivalent to 0.853 cal/cm3. [0010] In cooling from 0.degree. C. to -40.degree. C., 34.12 cal/cm3 is extracted. [0011] To lower one cm3 of water from +0.degree. C. to -40.degree. C. signifies the extraction of about 100 calories. This is three times the previous value. [0012] Ice is difficult to use for transferring cold rapidly and in a controlled manner to a packaged beverage. [0013] The quantity of cooling calories storable per unit volume of brine without freezing is much less than that of ice. Moreover it is not possible to maintain a uniform temperature by supplying cold since no phase change takes place. Its advantage is in the capacity to transfer cooling calories rapidly since the brine is in the liquid state. [0014] It is possible to store cold using a brine, of CaCl2 or NaCl, or an aqueous solution of glycol, in a reservoir provided with an evaporator of chilling fluid, usually a coiled tube, connected to a refrigerator compressor. [0015] The use of a cold accumulator with brine or another aqueous solution (without ice) is to be found in numerous patents, but with the solution always remaining separate from the product to be cooled with a membrane and without consumption of the solution used as observed in the patents U.S. Pat. No. 2,061,427 and U.S. Pat. No. 5,557,943 among others. [0016] Chilling with a very cold solution, usually brine, has been employed for a long time, for example for freezing fish. First immersion was used and then spraying with brine. [0017] On spraying, see for example the patents: DE-335871 and U.S. Pat. No. 1,468,050. [0018] Work has also been done on freezing diverse products by immersion in very cold brine, usually of Sodium chloride, at -20.degree. C. To avoid contact of the food with the brine a fine impermeable bag is used from which it is convenient to extract the air to allow a better contact, through the bag with the cooling liquid. The system is employed industrially for example to freeze chickens. The bag also allows the use of Calcium chloride or solutions of propylenglycol, etc. [0019] To cool cans of foodstuffs, fundamentally to lower the temperature after sterilization or pasteurisation, the system of spraying with water is used, generally at ambient temperature, with simultaneous rotation of the container which is displaced under the sprays. [0020] The rotation of the containers to augment the interior turbulence using horizontal rollers is to be found for example in the patent U.S. Pat. No. 4,164,851. [0021] The patent of invention U.S. Pat. No. 5,505,054 relates to a rapid cooling apparatus of in canned or bottled beverages which incorporates a system of spraying cold water in the range of 0.degree. to 5.degree. C. which projects from one or more nozzles a flow rate of at least 20 litres per minute onto the surface of the container to be cooled whilst the container disposed in a horizontal position turns at speeds of between 200 and 500 r.p.m. [0022] In this apparatus due to the use of cold water at temperatures greater than 0.degree. C., when it is attempted to reduce the temperature of the container to temperatures of the order of 5.degree. C., the application of substantial flow rates is required to avoid splashing and that the container rotate at a high speed to accelerate the cooling process.
