Definitions

  • This invention relates to devices for use in the rapid cooling of fluids in various containers, and more particularly to such devices suitable for cooling hot liquids such as soups, stocks, sauces, and the like, or pre-contained beverages such as soda, beer, energy drinks, or the like.
  • kitchens create stock to be used in gravy, soups, and other foods served along with meals.
  • the stock is made by cooking meat, bones, fat and the like in water to a temperature of 190° Fahrenheit to both pasteurize the mixture and allow the heated water to absorb the fat.
  • the pot is usually stored in either a kitchen sink or a refrigerator/freezer.
  • airborne contaminants may enter the stock, creating a safety and health hazard in the kitchen and ultimately to the consumer.
  • Bacteria also grows extremely rapidly in the temperature range between 140° and 41°F, often doubling every 20 minutes in this temperature range.
  • the stock often takes between 1 to 7 hours to chill depending on the quantity and method of chilling.
  • a cold paddle or ice paddle such as that described in U.S. Patent No. 5,058,396 to Faiola.
  • a plastic wand or paddle having one or more projections is filled with a cooling medium such as water, cooled or frozen in a refrigerator or freezer, and inserted into and stirred within the hot stock/food to hasten the cooling of the stock/food.
  • a cooling medium such as water, cooled or frozen in a refrigerator or freezer.
  • the paddle is made of a lightweight material such as plastic to make it easy to handle, however plastic is not an exceptionally efficient transmitter of heat (i.e., it has good insulative properties).
  • the paddle itself may also be contaminated with bacteria or traces of other foods into which it had previously been dipped, thereby directly introducing bacteria, allergens, or other undesirable foreign agents into the food.
  • operators tend to forget that water expands when it freezes, and they tend to fill the paddle completely with water prior to freezing. The result is that many such ice paddles crack when the water inside freezes and expands. Cracked paddles are extremely unsanitary and rapidly break down and must be replaced.
  • blast chiller which is essentially a very powerful refrigerator.
  • Typical blast chillers are manufactured by the Traulsen company of Fort Worth, TX.
  • a typical blast chiller will still take 90 minutes to cool 24 gallons of food from 135°F to 40 0 F.
  • Such a device would require about 2 1 A hours to cool 24 gallons of food from 190 0 F to 40 0 F and does not really benefit the commercial kitchen that generates up to 100 gallons of food at a time.
  • a typical blast chiller costs between $15,000 and $70,000, making it a very expensive appliance, especially for a small commercial kitchen.
  • a tumble chiller which resembles an extremely large washing machine. It consists of a 4-5 foot diameter rotating drum disposed within an even larger water bath, and it accepts 4-8 quart bags of food. The food bags are sloshed around in the drum until cool.
  • Typical tumble chillers are manufactured by the Cleveland Range company of Cleveland, OH.
  • the invention includes a method and system for rapidly cooling liquids, be they hot liquids such as stock, soup, sauces, or gravies, or beverages such as soda, juice, or beer.
  • the invention includes a method of rapidly cooling hot bulk liquids, comprising the steps of placing a hot bulk liquid in a sealable container having an inherent void volume, preferably of at least 5%, placing the container in a substantially horizontal orientation, rotating the container substantially about its longitudinal axis, and placing ice securely atop the container while the container is rotating.
  • the speed of rotation of the container may be varied depending on the viscosity of the hot bulk liquid to be cooled; the greater the viscosity of the hot bulk liquid to be cooled, the slower the rotation rate of the container during the rotating step.
  • the speed of rotation may also be varied depending on user preference, e.g., to avoid degradation of the food contents of the container.
  • the rotating step is preferably performed until the hot bulk liquid is cooled to approximately 4O 0 F. In addition or in the alternative, the rotating step is performed until a partial vacuum is created within the container.
  • the amount of ice to be used to chill a given container is preferably premeasured so that when the ice has completely melted, the container's contents are satisfactorily chilled.
  • a reservoir was provided to contain a cooling medium such as ice water.
  • the container is placed in a container bay having an open or openable top and walls dimensioned substantially the same as the container. Preferably, there is no more than a 1/8 inch space between the walls of the container and the walls of the container bay. Ice is placed atop the container after the container is placed inside the container bay. Because of the very narrow space between the container wall and the side walls of the container bay, the ice remains atop the container even as the container is rotated. As the ice melts, the contents of the container are chilled. Water from the melted ice drains out of the device substantially as it falls, i.e., it does not collect.
  • the invention is a compact rapid liquid chilling device.
  • a housing is provided including a container securing space adapted to secure a container of liquid to be chilled.
  • the container securing space is dimensioned to receive a quantity of ice and maintain substantially all of the ice atop a container placed in the container securing space and at least partially in thermal communication with the container without allowing substantially any of the ice to fall below the container.
  • a rotating mechanism is disposed in the housing in communication with the container securing space and is adapted to rotate a container placed in the container securing space.
  • the ice melts to form water as heat is extracted from the contents of the container, the water is allowed to fall freely below the container as substantially all of the as-yet unmelted ice remains above the container.
  • the water forms a thin film that is allowed to fall freely around the container while the rest of the unmelted ice remains above the container.
  • the housing includes a lid closable around the container, and the lid preferably includes an interior lid space that, when the lid is closed, forms a portion of the container securing space. More preferably, a window is formed in the lid adapted to allow ice to be supplied to the container securing space.
  • the housing includes a base which includes a first portion of the container securing space, and the lid includes a second portion of the container securing space when the lid is closed.
  • the inventive compact rapid liquid chilling device preferably includes an ice bin having side walls and an opening, the opening being adapted to fit together with the window in the lid.
  • the ice bin is adapted to allow the user to pre-measure the quantity of ice necessary to chill the contents of the container to a desired temperature.
  • the invention preferably includes at least one ice guard, disposed at an edge of the window and extending towards the container, adapted to substantially prevent ice from the ice bin from falling below the container.
  • a drain is preferably provided in the housing that allows the water that falls below the container to exit the housing.
  • a movable wall is provided selectively disposable within the housing and adapted to allow the user to adjust the volume of the container securing space.
  • the above-described compact rapid liquid chilling device includes a sealable container having an inherent void volume adapted to receive a liquid.
  • the invention also includes a method of rapidly chilling a liquid. First, a liquid at a higher-than-desired temperature is placed in a sealable container having an inherent void volume. The container is placed in a substantially horizontal orientation, and a quantity of ice is loosely and freely placed atop or otherwise in thermal communication with the container while being prevented from falling below the container. The container is rotated substantially about its longitudinal axis. The rotating step is performed until at least one of i) the liquid reaches a desired temperature or ii) all of the ice has melted. The speed of rotation may be varied according to user preference, e.g., to minimize food degradation during rotation.
  • the invention also includes a container for rapidly cooling hot bulk liquids by way of rotating the container about its longitudinal axis and cooling the contents of the container with ice placed securely atop the container as it is rotated.
  • the container includes a housing that is preferably substantially cylindrical and a top sealingly attachable to the housing.
  • the top includes an inherent void volume, preferably a void volume of at least 5% of the volume of the housing.
  • Attachment means are provided for sealingly attaching the top to the housing; a first mating portion of the attachment means is disposed on the housing, and a second mating portion of the attachment means is disposed on the top.
  • the first mating portion includes a first set of threads disposed on the housing and the second mating portion comprises a second set of threads disposed on the top.
  • the attachment means may include at least one of i) a bayonet fitting between the top and the housing; or ii) clips disposed on an exterior of the container (e.g., such as are found on a mason jar).
  • the inventive container may preferably include a projection disposed on an upper surface of the top. The projection facilitates tightening of the top onto the housing.
  • the container may, in addition or the alternative, include a recess formed on an underside of the housing.
  • the recess is adapted to fit atop a raised portion of a container tightening station to substantially prevent the housing from moving when a user tightens the top on the housing.
  • the container recess on the bottom of the housing is preferably substantially the inverse of the container projection on the top of the container, so that multiple containers can thus be stacked with enhanced stability.
  • the container may also include a liner disposed within the housing.
  • the invention also includes a system of rapidly cooling hot bulk liquids.
  • the inventive system includes a chilling station, which includes a container bay adapted to receive at least one container of liquid to be cooled. At least one rotator is adapted to rotate a container placed in the container bay substantially around the container's longitudinal axis.
  • the container bay has an open or openable top and walls dimensioned substantially the same as the container. Preferably, there is no more than a 1/8 inch space between the walls of the container and the walls of the container bay. Ice is placed atop the container after the container is placed inside the container bay.

  • device 8 includes a main housing 10 upon which lid 12 and hull 16 are disposed.
  • Lid 12 is preferably pivotably attached to hull 16 at pivots 14 and can open in the direction of arrow A (see Figs. IA and D).
  • Lid 12 includes a front wall 13, side walls 15, and a window or opening 19 formed in its upper panel 11.
  • upper panel 11 may be omitted entirely to leave the entirety of lid 12 open, for reasons explained below.
  • front wall 13, side walls 15, and hull wall 17 form a largely enclosed container bay 20 adapted to receive a container 60 (to be described below).
  • ice (not shown) be placed in bulk (preferably in cube or chip form) atop a container 60 inside container bay 20, either through window 19 or the open top of lid 12.
  • the tolerance between container 60 and the walls 13, 15, and 17 of container bay 20 are extremely small, on the order of 0.1 inches. Indeed, in many cases, container 60 will contract as it is chilled.
  • a 5-gallon stainless steel container having a plastic liner can contract as much as 0.5 inches in the longitudinal direction (there is typically less contraction in the diametric direction). As such, the tolerance mentioned above is for the cold, contracted container; it is even smaller or at or near zero for a hot, fully expanded container.
  • a front mount pad 24 provides cushioning and sealing for the lip of lid 20 when it is closed.
  • Passenger wall 26 supports container 60 as it rotates and helps prevent ice from falling below the container.
  • Motor 50 provides the actuation of roller 40; preferably, motor 50 includes a driver pulley 52 which communicates with roller pulley 44 via a belt (not shown).
  • Roller pulley 44 is coaxial with roller 40, so that rotation of roller pulley 44 directly causes rotation of roller 40. Owing to the frictional contact between rings 42 and container 60, as roller 40 rotates, container 60 rotates in the opposite direction.
  • Drain 32 is connectable to a hose or a spout or the like which allows the water to be conducted to a sink or a bucket. Because device 8 has no reservoir, unlike the previous Loibl stock chiller, it can be made much smaller and less expensively and can easily fit on a countertop in a small commercial kitchen such as found in a restaurant or bar.
  • device 8 can be made much less expensively than the previous Loibl stock chiller is by eliminating some or all of the controls concerning operation of motor 50 (and hence the rotation of roller 40).
  • Previous embodiments have included timing mechanisms which automatically shut off the device after a predetermined interval when the contents of the container are adequately chilled. Here, no timing mechanism is needed, because the device can be operated simply for as long as there is ice in container bay 20. When the ice is melted, the container is chilled. It is preferred that device 8 be provided with one or more ice measuring bins 100 (see Figs. 13 and 14, to be discussed below) that will pre-measure the correct quantity of ice for a given container and/or a given type of liquid to be contained.
  • Thicker sauces and soups may require more ice to chill than a thin stock, so a larger ice measuring bucket may be provided to chill sauces and soups.
  • the ice measuring buckets are adapted to be invertable atop window 19 and remain there full of ice, thereby extending the effective height of container bay 20 and allowing significantly more ice to be involved in the cooling process than what can fit inside container bay 20 below window 19. In any event, by providing a preset amount of ice for a preset size of container, proper chilling of the contents is assured.
  • Housing 10 includes handles 30 for easy transport and portability.
  • Hull 16 includes hull support feet 22 (see Fig. 2B) for supporting the bottom of the hull, which can get quite heavy (upwards of 18 kg) once a full container 60 and ice are added to container bay 20. It is preferred that device 8 only be moved when not in use and when container bay 20 is devoid of either container 60 or ice.
  • Figs. 11-16 depict an embodiment of the invention similar to that shown in Figs. 1-2. Like elements are given like reference numerals, and description thereof will not be repeated.
  • Device 8' includes a main housing 10 upon which lid 12' and hull 16 (see Figs. 12, 15, and 16) are disposed.
  • Lid 12' is preferably pivotably attached to hull 16 at pivots 14 and can open in the direction of arrow A (see Fig. 12).
  • Lid 12' includes a front wall, side walls, and an upper window or opening 19.
  • the front wall and side walls of the lid and hull 16 form a largely enclosed container securing space or container bay 20 adapted to receive a container 60 (see Figs. 12 and 16).
  • a portion of the container securing space 20 is inside housing 10 and hull 16, and the remainder is inside the interior of lid 12'. Ice (not shown) is to be placed in bulk (preferably in cube, chip, or crushed form) atop container 60 inside container bay 20 through window 19 as described below.
  • the tolerance between container 60 and the walls of the container securing space 20 are extremely small, on the order of 0.1 inches. As such, after the ice is placed atop container 60, substantially all of the ice remains atop the container and substantially none of the ice falls below the container into the bottom of the device.
  • motor 50 provides the actuation of roller 40; preferably, motor 50 includes a driver pulley 52 which communicates with roller pulley 44 via a belt (not shown). Roller pulley 44 is coaxial with roller 40, so that rotation of roller pulley 44 directly causes rotation of roller 40.
  • a device 8 or 8' utilizing a 3-inch driver pulley 52 and a 3-inch roller pulley 44 can produce container rotational speeds of approximately 150 rpm.
  • the user may wish to have a slower speed of rotation for reasons such as preventing food degradation (e.g., some of the solid portions of the food, e.g., vegetables, may disintegrate when rotated at 150 rpm).
  • a 1- inch driver pulley 52 and a 4-inch roller pulley can be used to produce container rotational speeds of approximately 40 rpm.
  • the slower rotational speed will slightly lengthen chill times of the contents of the container, however even the longer chill time is still most satisfactory (e.g., 8 minutes rather than 6 minutes), and the user does not have to suffer food degradation or the like.
  • the invention adapted to chill optimally at rotational speeds of 30-250 rpm.
  • housing 10 includes a passenger wall 26 (see Fig. 12) that supports container 60 as it rotates, provides a low-friction interface between the container and the device, and helps prevent ice from falling below the container.
  • Lid 12' also includes a passenger wall 131 (see Figs. 11 and 16) that supports container 60 as it rotates and provides a low-friction interface between the container and the lid to protect the material of both the container and the lid.
  • At least one and preferably two ice guards 122 are provided in lid 12' near window 19, which help to prevent the ice disposed atop container 60 from falling into the bottom of the unit.
  • the tolerance between ice guards 122 and container 60 is preferably in the range of .16 - .20 inches. Tight tolerance is necessary to prevent the ice from falling past the container, however too tight a tolerance between ice guards 122 and container 60 is not desirable, as it causes water to pool on top of the container in window 19 rather than form the preferred thin film around the container.
  • Guide walls 124 help to prevent container 60 from moving back and forth, and they also help prevent the ice from falling past the container.
  • the tolerance between guide walls 124 and the top and bottom of container 60 is preferably in the range of .16 - .20 inches when the container is fully chilled and contracted; the tolerance is at or near zero when the container is in its hot, fully expanded state.
  • Latch 133 is provided to lock down lid 12' to housing 10 in a closed position to ensure lid 12' does not open during operation of the device, and to ensure that the addition of ice atop the container does not force the lid open and allow the ice to fall below the container.
  • Ice bin 100 preferably has side walls 102, 104, 106, and 108, an open top 103, and an open bottom 105. At least one and preferably two handles 101 are provided on opposing side walls, e.g., side walls 104 and 108 as shown in Figs. 13 and 14A, to facilitate the ice bin's placement atop and removal from lid 12' (or lid 12 of Figs. 1-2).
  • the cross section of ice bin preferably decreases from top to bottom, i.e., open top 103 is larger than open bottom 105, and side walls 102 and 106 are preferably trapezoidal in shape. This creates a funneling effect to best position and maintain the ice atop the container. It is preferred that open bottom 105 be dimensioned and adapted to matingly engage window 119 of lid 12' . In that way, bin 100 may be attached to or simply placed atop lid 12' (or 12) to provide a large volume of bounded space in communication with window 19 for containing an adequate supply of ice for chilling the contents of a container.
  • ice bin 100 is sized so as to contain the proper amount of ice when full to ensure proper chilling of the liquid contents of a container of a predetermined size regardless of the liquid's type or starting pre-chilled temperature. Since the liquid in question is preferably soup, stock, or sauce, which are all predominantly water-based, the liquid contents of container 60 will never realistically exceed 212 0 F. As such, knowing the volume of the container and its maximum potential temperature, an approximate amount of ice can be determined which will assuredly chill even the hottest contents.

Multiple slots 117 may be provided to accommodate multiple lengths of cans (e.g., 8 oz., 12 oz., 16 oz., etc.).
  • device 109 works as follows. First, the proper position of baffle 116 is selected. Can 160 is placed inside container bay 120 atop roller 140. Ice is added atop can 160. Because of the close proximity of side walls 112, baffle 116, and rear wall 114 to can 160, ice placed thereupon does not fall below can 160 but rather remains atop the can. Motor 150 is activated, causing roller 140 to rotate. Frictional rings 142 grip the side wall of can 160 and cause can 160 to rotate as well. Preferred rotational speeds for this embodiment range from approximately 200 to approximately 400 rpm, though slower and faster speeds are also contemplated.
  • the lid is shown as pivotably attached to the hull or housing.
  • the lid may be attached via a sliding mechanism, or in any other convenient manner, or it may be completely separable and not permanently attached at all.
  • the ice bin volume may be made integral with the lid, i.e., the lid may be made larger to accommodate hold and all of the ice required to chill a container.
  • the lid may be done away with, and an ice bin adapted to be disposed directly onto the housing may be provided. In other words, rather than incorporating the ice bin volume into the lid, in this case, the lid function is incorporated into the removable ice bin.
  • the embodiments shown in the drawings and described above have the ice directly contacting the portion of the container accessible through the window.
  • all that is required is that the ice be in thermal communication with the container.
  • an intermediate structure may be provided that allows thermal communication between the ice and the container but prevents the ice from falling below the container.
  • Such a structure takes the form of a mesh, fabric, or tight lattice barrier, preferably flexible, so as to allow the ice above to mold itself to the contours of the container without falling, and also to allow the water formed from the ice melting to form a thin film around the container.
  • the drive mechanism described above includes a motor having a pulley with a belt connected to a pulley on the roller.
  • any other drive mechanisms are also contemplated as being within the scope of the invention, e.g., a direct drive mechanism. Rotational speeds of these type of drive mechanisms can be varied as known in the field, e.g., by varying the voltage delivered to the drive.

Abstract

La présente invention concerne un appareil compact de réfrigération rapide de liquide et son procédé. Un liquide est placé dans un récipient présentant un volume vide intrinsèque. Le boîtier comprend un espace de fixation de récipient dimensionné pour recevoir de la glace et maintenir pratiquement toute la glace au-dessus du récipient placé dans ledit espace de fixation, en communication thermique avec le récipient, en empêchant sensiblement la chute d'une partie de la glace sous le récipient. Un mécanisme rotatif disposé dans le boîtier entraîne en rotation le récipient placé dans l'espace de fixation de récipient. À mesure que la glace fond en refroidissant le récipient rotatif, l'eau résultante s'écoule librement sous le récipient puisque que pratiquement toute la glace non fondue reste au-dessus du récipient. Un couvercle, se referme autour du contenant, de façon à délimiter une partie de l'espace de fixation de récipient lorsqu'il est fermé. Le couvercle comprend de préférence une fenêtre de chargement de glace, et un bac de mesure de glace peut de préférence venir se monter sur ladite fenêtre.
