Definitions

  • the present invention relates to chillers and freezers, and more particularly, to chillers for small articles such as beverage cans, perishable foods, and the like.
  • Bottled and canned beverage coolers and chillers wherein the bottled or canned beverages are cooled in a body of chilled liquid are not per se new.
  • U.S. Patents have been issued over the years relating to such beverage coolers or chillers, some of which are: United States Patent Nos.: 2,287,581 (Hazard); 2,418,300 (Hagstrom); 2,436,426 (Fish); 2,546,417 (Anglin); 2,618,127 (Shyman); 2,812,643 (Woschitz); and 4,377,076 (Staudt, et al.)
  • salt-brine can be used to prevent the water from freezing at 32°F
  • the salt-brine solution leaves an undersirable smell and residue on the article to be chilled and vigorously chemically attacks various metal parts used in the refrigeration unit.
  • None of the prior art devices related to beverage cooling provide a means for quick freezing of non-beverage articles.
  • None of the prior art devices related to beverage cooling provide a means for eliminating the chilling fluid residue from the articles to be cooled or chilled, whereas the present design uses variations utilizing time, vibration, air, rinse cycle and/or vacuum to eliminate fluid residue.
  • None of the prior art devices relating to beverage colling utilize a chilling liquid which if beverage liquid contamination occurs, such as by leaking from the beverage container, operates at temperatures far enough below 32°F to immediately convert the beverage material into a solid which by separating it from the chilling liquid, inherently prevents contamination of the chilling liquid medium.
  • None of the prior art devices known and shown herein utilize a flow header to force chilling medium to flow over and around the product from the walls of the insulated tank or container in which the cooling or chilling liquid is maintained.
  • none of the prior art chilling or freezing units can function similar to a "reverse" microwave over wherein the articles are chilled or frozen, as desired, by the extremely rapid removal of heat which is the "reverse” of what a microwave oven does, that is, produce an extremely rapid addition of heat to an article.
  • beverage immersion chillers have been largely replaced by non-liquid immersion (chilled air) refrigeration chilling and/or freezing systems; and currently immersion chillers for freezing food have had to resort to expendable type refrigerants such as LN 2 , C 0 2 , R-12, which require complicated and costly recovery systems.
  • Such "non-liquid” refrigeration systems are, however, relatively inefficient with respect to energy usage and cost when compared to liquid immersion-type systems.
  • the heat transferring characteristics of chilled air, or any other "non-liquid” cannot compare with the heat transfer ability of chilled liquids which are 100 to 1000 times more efficient than any air chilling medium.
  • Another important and primary object of the instant invention disclosed herein is to provide a method of rapidly chilling and/or freezing articles without leaving an undesirable residue on the chilled or frozen article.
  • a chemically inert chilling or freezinq liquid at 25°C STP such as the families of liquid fluorocarbon chemicals, various formulations of alcohol and water ranging from 40% to 60% alcohol, brines-glycol, salts and water.
  • Another object of the invention is to use a chilling and/or freezing method which utilizes a cooling or freezing liquid which has a surface tension characteristic substantially below that of water.
  • Fig. 1 is a vertical elevation view of a first embodiment of the invention, shown partially in section, detailing the inside of the insulated cabinet in which the articles to be chilled or frozen are placed and diagrammatically the various elements necessary to chill the liquid and to place the articles to be chilled or frozen therein; and Fig. 2 is a view similar to Fig. 1 showing a second embodiment of the invention.
  • the invention herein is generally indicated at 100 and is referred to as an apparatus for rapidly chilling and/or freezing articles, especially beverage containers and foods 34, including an insulated container 40 having an open top, a lid 41 covering the open top of the container 40, a refrigerated liquid 38 having a relatively low surface tension, such as the family of liquid fluorocarbon chemicals or an alcohol-water mixture ranging from 40% to 60% alcohol or salt or glycol brine solutions, a refrigeration unit, generally indicated at 101, comprising a condensing unit 21, an evaporation assembly 16, and a thermostatic expansion valve assembly 19A and 19B, passageway and pump means 18 for recirculating the liquid 38 to be refrigerated past the evaporator coils and up to the product chamber, a produce chamber 12 for holding the articles to be chilled or frozen, drain holes 36 for the draining the fluid, an overflow drain 13 for handling overflow, a flow header 17 for circulating a directed stream of coolant over the product, a bottom grill 23 for elevating the
  • the insulated container, generally indicated at 40 is preferrably formed of a rectangular structure, having four sidewalls 39 and a bottom wall 42.
  • the sidewalls 39 and the bottom wall 42 ar formed of a thermal insulation type of material 29 having a relatively high R (heat loss resistance) value, such as synthetic plastic foam.
  • R heat loss resistance
  • Other suitable thermally insulating materials for the sidewalls 39, bottom wall 42 are all well known per se and, therefore, need not be described in detail.
  • the exterior skin 30 surrounding the sidewalls 38, bottom wall 42, and the lid 41 of the container 40 is typically formed of stainless steel sheet material which is a relatively poor conductor of heat, or other similar durable, rugged, and self-supporting material.
  • Such self-supporting material provides protection for the enclosed insulation 29.
  • the insulated container 40 and lid 41 combination are primarly used for containing the refrigerated liquid 38 which is used to chill or freeze the articles desired.
  • the sidewalls 39 are joined to an adjoining cabinet 43 which houses the other portions of the invention herein.
  • a hinge 2 is mounted along one edge of the lid and is secured to the upper portion of the sidewall 39 of the container 40.
  • a handle 1 is secured along one of the edges of the lid 41 not secured to the hinge 2. The handle 1 allows the hinged lid 41 to be opened and closed as desired for placing the articles to be chilled or frozen therein or to be removed therefrom as desired.
  • a product holding tray 12 is formed with sidewalls in near conformance with the interior dimensions of the container 40 and a total volume approximately one quarter to one third that of the interior dimensions of the container 40.
  • An overflow drain 13 prevents the liquid from overflowing and returns the liquid to the lower chamber.
  • a plurality of apertures 36 are formed in the bottom of the product tray 12 to allow the refrigerated non residue forming fluid 38 to drain off of the tray 12 after flowing onto the tray by means of pump 18 or gravity so as to permit direct contact with the articles to be chilled or frozen.
  • a solenoid arrangement not presently described is used to separate coolant return from rinse cycle.
  • the tray 12 is formed of a material which complements, or is identical, to the material forming the skin 30 of the container 40. In the preferred embodiment of the invention set forth herein the material is stainless steel.
  • a product immersion grill 20 is attached to the lid 41 so that when the lid is closed the product immersion grill 20 insures that product does not float and remains immersed in the liquid coolant 38 stream flowing out of the flow header 17.
  • a perforated bottom grill 23 Resting in the chamber is a perforated bottom grill 23, which elevates the product above the bottom of the tray 12 so that circulation of the liquid 38 from the flow header 17 proceeds around the entire product and so that the product remains elevated from drain pools and does not close off the drain holes 36.
  • a vibrator 22 is an optional means of vibrating excess coolant 38 from the product.
  • Drain and rinse solenoids 44A and 44B are designed to control the rinse header 24 cycle and to prevent undesirable residue and the rinse cycle liquid (H 2 0) from contaminating the liquid 38 in the container 40.
  • a relief orifice 37 drains the rinse cycle liquid (H 2 0) and the undesirable residue, and because it is encased in the insulation liner 29, prevents the rinse cycle water from freezing.
  • a float valve 25A and float switch 25B monitor and control the liquid coolant 38 level so that it does not fall below critical operating levels without triggering an alert beeper or shutting off the unit.
  • door lid seals 3 are placed on the bottom of the lid 41 approximately 1/2" from the edge and again a couple of inches from the edqe on all sides so as to create an air barrier between the inner and outer lid seal 3.
  • a magnet lid switch 4 which is connected to the pump 18 and where applicable, the drain solenoid 44A, is designed to shut off the pump and/or activate the drain when the lid 41 is raised more than a couple of inches in order to prevent individuals from being able to come into prolonged contact with the liquid coolant 38.
  • the duration of time during which the coolant circulates in the tray 12 containing the articles disposed therein for chilling or freezing is determined in a conventional manner by the use of an electrical timer 5, the output of which is coupled to the control box assembly 20.
  • An indicator light 7 is operably connected to the timer 5 in conventional well-known fashion and remains "on” or lit as long as the pump 18 is circulating the refrigerated liquid 38 in the tray 12.
  • the timer 5 output is directed from the control box assembly 20 to the circulation pump 18 and to a beeper.
  • an evaporator or cooling element 16 in the form of a series of coils.
  • the liquid 38 to be refrigerated is pumped by a liquid pump 18 through a passageway beneath the bottom wall of the chamber in the container 40 to the tray 12.
  • the liquid 38 is delivered to the opposite side of said tray 12 by a flow header 17 and by means of drain holes 36 into the compartment containing the evaporator 16. After the liquid 38 passes thereinthrough, it is directed upwards to the tray 12 again by means of the pump 18.
  • the refrigerating system is conventional which includes a refrigerant liquefying unit comprising an electric motor driving a compressor 21 through conventional belt and pulley connections.
  • a condensor is also provided with a motor-driven fan to drive air thereinover.
  • a pair of temperature sensing elements 15B and 19B are used to operably control the refrigeration unit in a conventional fashion.
  • the temperature sensing means 15B is positioned within the bottom of the chamber within the container 40 so as to be responsive to the temperature of the body liquid 38 therein, and communicates electrically with a temperature contrller 15A for controlling the compressor 21 motor of the refrigeration system.
  • the compressor 21 withdraws evaporated refrigerant from the evaporator 16 through the conduit identified as the "low pressure side" and compresses the refrigerant vapor whereupon it is forwarded under pressure through a conduit into the condensor. Fan driven air is circulated over the condensor and causes condensation of the compressed refrigerant and then flows into the receiver.
  • the condensed refrigerant is conveyed, by a conduit, to the "high pressure line.”
  • the temperature sensor 19B electrically activates the refrigerant expansion valve 19A thereby allowinq the pressurized refrigerant to pass through the expansion valve 19A to the evaporator or cooling coil 16, thereby chilling the liquid 38 thereabout.
  • FIG. 2 a second embodiment of the invention is shown in which the same reference numerals are used for the same parts shown in Fig. 1.
  • Attached to product tray 12 for holdino the articles to be chilled or frozen is a double-acting air cylinder means 17, including a shaft 13 which is operably coupled to the product tray 12, and air compressor means 25 for providing a source of compressed air for operating the air cylinder means 17, and an electric solenoid 23 for operably controlling the air delivery to the air cylinder means 17, including the necessary electrical switches 5 for controlling same.
  • a double-acting air cylinder 17 Operably coupled to the tray 12 is a double-acting air cylinder 17 which is so coupled to the tray 12 by means of a shaft 13 of the air cylinder 17. Connection is typically made therebetween by means of a threaded shaft end and a nut (not detailed).
  • the air cylinder 17 and its associated shaft 13 is powered by a supply of compressed air provided by the air compressor 25.
  • the compressed air output from the air compressor 25 is piped directly into an air storage tank 22.
  • the air storage tank 22 is needed to provide a storage plenum, at operating pressure, for the air supply. Without such storage, at pressure, there would not typically be a sufficient quantity of air to operate the pneumatic control systems properly of which the air cylinder 17 is a part.
  • control system could just as easily be hydraulic.
  • use of a hydraulic system is not necessary and in the event that such as system were to be used, it would cause the weight of the overall system to be substantially increased as well.
  • Control of the air to the cylinder 17 is accomplished by an electrically-controlled two position solenoid valve 23.
  • the solenoid valve 23 When the air cylinder 17 needs to drive the shaft 13 and, of course, the product tray 12 upwardly to its position above the refrigerated liquid 38 level, the solenoid valve 23 is actuated and causes compressed air from the air storage tank 22 to be piped to one of the air lines leading to the air cylinder 17. The compressed air then causes the air cylinder 17 to drive the shaft 13 upwardly as desired.
  • the small magnet 10 mounted appropriately on the outer rim of the top of the rack 12 is placed into close operative proximity to the magnetic switch 9 which, in turn, is electrically connected to the control box assembly 20, and directed therefrom into operative electrical coupling to the solenoid valve 24 which momentarily is opened allowing the compressed air from the air storage tank 22 to be fed via tubing to the air blast header assembly 11 thereby allowing compressed air to exit the apertures 37 in the header assembly 11 to perform the air blasting function previously described.
  • the duration of time during which the tray 12 and the articles disposed therein for chilling or freezing is determined in a conventional manner by the use of an electrical timer 5, the output of which is coupled to the control box assembly 20.
  • An indicator light 7 is operably connected to the timer 5 in conventional well-known fashion and remains "on” or lit as long as the tray 12 is immersed in the refrigerated liquid 38.
  • the timer 5 output is directed from the control box assembly 20 to the air solenoid 23 which operably directs the solenoid 23 to raise or lower the tray 12 out of or into the refrigerated liquid 38.
  • An air venting system may, as desired, also be provided which communicates into the inside of the air container 40, consisting of an air vent line 27, an air vent one-way valve 28, and a condensate removal sump and pump assembly 26. Because the lid 41 on the container 40 creates a reasonably air tight condition, the movement of the tray 12 up and down within the closed chamber formed by the combination of the lid 41 and the container 40, a vacuum or higher air pressure can be created within the chamber. To prevent the fluid seal between the lid 41 and the container 40, and other fluid seals found therein as well, from being disturbed and, 'perhaps, damaged to the point of becoming non-functional this air venting systems is provided.
  • the air As the air attempts to move out of the chamber, it is diverted down the air vent line 27 to the one-way air vent valve 28 and is vented to atmosphere or the line operably coupled to the condensate removal sump and pump 26. Once it is in the sump and pump 26, it can be easily pumped therefrom.

  • the temperature sensor 19B pneumatically activates the refrigerant expansion valve 19A thereby allowing the pressurized refrigerant to pass through the expansion valve 19A to the evaporator or cooling coil 16, thereby chilling the liquid 38 thereabout.
  • One of the many unique characteristics of the present invention disclosed herein includes the use of a refrigerated liquid in an immersion chilling device which is refrigerated to substantially below the freezing temperature of water; namely: +32°F or 0°C. Neither has there been the use of such a refrigerated liquid which is necessary to significantly reduce or eliminate residues from accumulating on the article or product to be chilled or frozen.
