## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
The present application claims priority from U.S. provisional patent application Ser. No. 60/501,348, filed Sep. 8, 2003, titled “Form of chilled and constant concentration beverage”.


FIELD OF THE INVENTION
The present invention relates in general to beverage forming systems. More particularly, the present invention relates to beverage forming systems for chilled beverages with constant concentration.
BACKGROUND OF THE INVENTION
Existing beverages commonly found in private and public places are typically chilled in refrigerators, or dispensers or chilled by adding water ice cubes. A variety of cold beverage dispensing systems have been designed to produce chilled beverages, such as frozen or slush beverages, chilled juice drinks, chilled alcoholic mixtures, milkshakes, fruit juices, nectars, etc.
Existing cold beverage systems do not adequately address the difficulty of continuously dispensing quality chilled beverages and maintaining the cold beverage in the required low temperature until the beverage is consumed. The degree of freezing and texture of a chilled beverage is important in providing a quality beverage. Similarly, the consistency of the freezing and texture is very important to customers in ordering drinks. If water ice cubes or crushed ice are added to the beverage to maintain its low temperature, the concentration of the beverage is diluted, and therefore, its quality is typically damaged.
In case of bottled beverages, the dilution of the original beverage typically begins substantially immediately when the ice is melting. In case of beverage dispensers, where water and syrup beverages are mixed before cooling and pouring, the beverage dispenser is typically programmed in such a way that during pouring the serving of the drink the concentration of the syrup in the beverage is bigger, and the beverage is typically diluted with the time passing because the water ice melting.
In addition, water ice cubes or crushed ice typically take the place of the beverage in the beverage container, and therefore the consumer does not receive the full capacity of the container in the beverage. Ice cube manufacturers recommend 50% of volume of cup filled with ice.

It should be understood, however, that the description herein of specific embodiments is not intended to limit the invention to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.
DETAILED DESCRIPTION OF THE PRESENT INVENTION
Illustrative embodiments of the invention are described below. In the interest of clarity, not all features of an actual implementation are described in this specification. It will of course be appreciated that in the development of any such actual embodiment, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which will vary from one implementation to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.
Reference is now made to FIG. 1, which is a diagram of a container 10 filled with a chilled beverage 101 in accordance with some embodiments of the present invention. It should be further noted that the term “beverage” as used hereinafter includes a food liquid meant for human consumption in which the solvent is water. Chilled beverage 101 may be, for example, formulated as a non-carbonated or carbonated drinks. The following are non-limiting examples of beverage: beer, wine, liquor, liqueurs or any other consumable alcoholic liquids, including those mixed with non-alcoholic liquids; soft drinks; juices and juice-based drinks; milk and milk-based drinks; flavored and non-flavored waters; frozen drinks (including in the form of ice, crushed ice, slush, smoothy, or shake); coffees; teas; and wellness drinks, including nutri-ceuticals, energy drinks, or isotonic drinks.
Chilled beverage 101 may include frozen microscopic particles 102 made from the same composition of beverage 101, and therefore, the concentration of the beverage may remain substantially constant if desired. It should be noted that the term “constant concentration” as used hereinafter refers to a relatively fixed amount of material, e.g., syrup, powder, active ingredient or any other soluble substance dissolved in a unit of solution or mixture.
Frozen microscopic particles 102 may be configured as a core of microscopic ice crystal surrounded by a soluble substance, e.g., syrup, utilizing substantially the same concentration of the beverage itself. The range of the size of the frozen microscopic particles 102 may vary, and preferably the size may be determined to be not more than 30 microns. The size and the configuration of frozen microscopic particles 102 may ensure that they do not stick together and may not hamper or influence the drinking process. It should be noted that the frozen microscopic particles 102 may be passed easily through a straw due to their small size. Additionally, the relatively low weight of the frozen microscopic particles 102 may cause them to float to the surface of container 10, creating an appealing airy type cloud at the top of the container 10.
In accordance with some embodiments of the present invention, the temperature of the chilled beverage 101 may be, for example, 40° C., at the time that the beverage is poured, and the temperature of the microscopic particles 102 may be, for example, −20° C. As a result, the temperature of the chilled beverage 101 may remain low until all microscopic particles 102 are melted, without changing the concentration of the beverage.
Reference is now made to FIG. 2 which is a schematic diagram of a system 20 for continuous cooling and dispensing beverage in accordance with some embodiments of the present invention. Beverage 21 may be dispensed into system 20 through an inlet hose 22. The temperature of beverage 21 does not effect the operation of system 20 and it may be relatively hot, e.g., above 20° C., or relatively cold, e.g., below 8° C. Beverage 21 is inserted to a beverage forming unit 23 that may cool and form beverage 21 to a predetermined temperature and texture as will be described in details below. Beverage 21 may be cooled in beverage unit 23 by, for example, a cold gas. Beverage 101 with frozen microscopic particles 102 may be dispensed through a tap 24 to a container 10. When tap 24 is closed, the beverage 101 with the frozen microscopic particles 102 may be directed or routed to a defrosting unit 25 that may defrost the frozen microscopic particles 102 in order to restore the beverage to its original texture. Beverage 101 with the frozen microscopic particles 102 may be defrosted by, for example, the gas that may have been used to cool the beverage in the beverage unit 23. Beverage 21, after the defrost process, may then be directed to beverage forming unit 23. It may be understood that as long as tap 24 is closed, since the beverage may be directed from the beverage forming unit 23 to the defrosting unit 25 in a circular continuous motion, substantially at any point, beverage 101 with frozen microscopic particles may be dispensed through tap 24 to a container 10 for serving and consumption.
Reference is now made to FIG. 3, which is a simplified top view block diagram illustration of an exemplary beverage forming unit 23 for cooling beverage 101 and forming frozen microscopic particles 102, in accordance with some embodiments of the present invention. Beverage forming unit 23 may include a shaft 231 which may be positioned within the center of heat transfer tube or container 233. The diameter and depth of shaft 231 and heat transfer tube 233 may determine the volume 237 of the beverage that may be cooled and formed by beverage forming unit 23. At least one blade 232 may be connected to the shaft 231 in such a way that blade 232 may scrape the surface of the heat transfer tube 233. Heat transfer tube 233 may be placed within a cooling medium 234 that may cool the beverage in heat transfer tube 233. Beverage forming unit 23 may also include an insulator 235 and a cover 236 which may be made, for example, of stainless steel. Beverage cooling unit 23 may also include a motor (not shown) to provide a relative motion between heat transfer tube 233 and blade 232.
Beverage 101 may be entered to the heat transfer tube 233 and it may be cooled, for example, to −1° C., or to any other freezing temperature of beverage 101. Blade 232 may scrape the frozen microscopic particles 102 formed on the surface of heat transfer tube 233 and mixed to the beverage 101 in a fixed ratio.
The size of the frozen microscopic particles 102 and the rate of their growth may be determined by several conditions such as, for example, the rotation speed of blade 232, the temperature of beverage 101, the temperature of cooling medium 234, the quality and level of polish of the inner surface of heat transfer tube 233, the volume of heat transfer tube 233 etc. In accordance with some embodiments of the present invention, the size of the frozen microscopic particles 102 may be determined to be not more than 30 microns. It should be noted that frozen microscopic particles 102, because of their small size, may not be grasped or felt by the human tongue or other parts of the mouth. In addition, frozen microscopic particles 102 may not stay in the container 10 as sediment when the beverage is consumed.
In accordance with some embodiments of the present invention the volume of the frozen microscopic particles 102 relative to the liquid particles, for example, may be determined to a fixed percentage of the total amount of the beverage, or it may be set to reach a volume that maintains the beverage in a predetermined temperature. For example, in a fixed percentage mode, the system may be configured to contain at least 10% of microscopic particles. Alternatively, in another example, it may be set to contain microscopic particles to maintain the beverage at 4° C. for 20 minutes, when the temperature outside the heat transfer tube 233 is 20° C.
Reference is now made to FIG. 4 which is a simplified top view block diagram illustration of the formulation of microscopic particles 102 on the surface of the heat transfer tube 233. Components of FIG. 4 that are similar to that of FIG. 3 are designated with the same reference labels, and for the sake of brevity the description is not repeated. Blade 232 may scrape the frozen microscopic particles 102 from the surface of the heat transfer tube 233 when the frozen microscopic particles 102 reach a maximal predetermined size. Substantially immediately after blade 232 scrapes the surface of the heat transfer tube 233, a new cycle of growth of frozen microscopic particles of the beverage may begin.
Reference is now made to FIG. 5 which is a simplified side view block diagram illustration of a system 50 for continuous cooling and dispensing beverage 101 according to some alternative embodiments of the present invention. System 50 may include a cooling chamber 501 with an inlet hose 502 and an outlet hose 503. Cooling chamber 501 may cool the beverage within system 50 by, for example, passing cold liquid or gas between the two sides, 504A and 504B, of the cooling chamber 501. In accordance with some embodiments of the present invention, a cold gas may be introduced at the first side 504A of the cooling chamber 501. The cold gas may then be evaporated to cool the beverage 51 and in the second side 504B the gas may be evaporated to defrost the beverage in the defrost unit as was described in FIG. 2. Beverage 51 may be dispensed through inlet hose 502 into the cooling chamber 501. As a result of the temperature difference between beverage 51 when it is dispensed into the cooling chamber 501 and the internal surface of the cooling chamber 501, beverage 51 may start freezing on the inner surface of the cooling chamber 501 and frozen microscopic particles may be created alongside the inner surface of the cooling chamber 501. In accordance with the described embodiment, scraping devices 505 may scrape the inner surface and mix the microscopic particles within the beverage 51. It is noted that many scraping devices may be utilized to scrape the inner surface of the cooling chamber, for example, scraping blades or sweeping devices. The scraping devices 505 may be in a constant motion, e.g., in a cylindric motion around a shaft 510 positioned in the center of the cooling chamber, or in a perpendicular motion along the inner surface of the cooling chamber 501, etc. A motor 520 may be connected to shaft 510 to provide the relative motion between the scraping devices 505 and the inner surface of the cooling chamber 501. Beverage 51 with the frozen microscopic particles mixed in it may be dispensed through outlet hose 503 into a container, e.g., a cup, for serving and consumption (not shown).
Reference is now made to FIG. 6 which is a schematic flow chart of a method for continuous beverage forming and dispensing in accordance with some embodiments of the present invention. Initially, the characteristics of the beverage may be determined (block 100). The characteristics may include, for example, the size of the beverage microscopic particles, the target temperature of the beverage with the beverage microscopic particles, the texture of the beverage (e.g., the distinctive, underlying pattern or structure of the beverage), the volume of the frozen microscopic particles, etc. Thereafter, the beverage may be entered to a container, such as, for example, a heat transfer tube (block 200), and the beverage may be cooled until frozen microscopic particles may begin to formulate on its inner surface (block 300). The frozen microscopic particles may then be scraped from the inner surface of the container (block 400) and mixed with the beverage until the beverage is in the required condition, e.g., reached the predetermined temperature, texture, etc. (block 500). Then, if there is an immediate need for the beverage with the frozen microscopic particles (block 600) the beverage with the frozen microscopic particles may be dispensed to a container for serving and consumption (block 700), or alternatively, the beverage with the frozen microscopic particles may be defrosted (block 800) and then entered to the heat transfer tube (block 200) and so on.
It will be appreciated that the present invention is not limited by what has been described hereinabove and that numerous modifications, all of which fall within the scope of the present invention, exist. For example, while the present invention has been described with respect to the use of blades to scrape the microscopic particles from the surface of the heat transfer tube, other components may be used to release the microscopic particles from their formation surface.
It will be appreciated by persons skilled in the art that the present invention is not limited by what has been particularly shown and described herein above. Rather the scope of the invention is defined by the claims which follow:
