Definitions
- the present invention relates to a device for cooling a drink, comprising a drinking tube, a cooling body with a cooling chamber, an insulating element, sensors and controllers and, if appropriate, a container for the coolant, in particular liquid nitrogen, provided for connection to the device.
- Such a device in which, in particular, liquid nitrogen is used as a coolant.
- Another aspect of the invention relates to a method of chilling a beverage, wherein the beverage is drawn from a beverage container through a drinking tube into the mouth of the drinker, and wherein the beverage flows through a device as previously described while being cooled to a desired temperature.
- the device of the present invention includes a drinking tube that includes a lower portion for insertion into the beverage, a middle portion for cooling the beverage, and an upper portion for insertion into the drinker's mouth.
- the middle section of the drinking tube is surrounded by a cooling body which contains a cooling chamber which is intended to hold the coolant, in particular liquid nitrogen.
- the middle portion of the drinking tube is designed to allow efficient heat exchange between the beverage flowing through the drinking tube and the coolant.
- the length of the section through which the liquid flows in the device can be increased and the cooling effect can thus be increased if the drinking tube has a curved shape, e.g. the shape of a helix, a spiral or a double helix, at least in the area of its middle section.
- the drinking tube can be branched at least in the area of its middle section.
- the heat exchange between the coolant and the drinking tube can be increased if its surface has a roughened surface at least in the area of its middle section towards the outside, i.e. towards the cooling chamber.
- the cooling body contains at least one opening for coolant to enter the cooling chamber and/or for coolant to exit the cooling chamber.
- An insulating element is arranged around the heat sink, which is provided for thermal insulation from the outside, so that the device can easily be handled by the drinker.
- the sections of the drinking tube are conveniently formed integrally with one another, i.e. they are made from a single piece.
- the drinking tube in turn is conveniently formed integrally with the heatsink and optionally integrally with the insulating member arranged around the heatsink, i.e. they are made from a single piece of material.
- These parts are preferably made of a mechanically and thermally stable material, e.g. a metallic material, in particular a high-quality metal alloy, e.g. an iron-based metal alloy such as steel, e.g. V2A steel or V4A steel.
- the device can comprise a control unit, by means of which the degree of cooling of the beverage is regulated.
- the control unit can contain a suitable electronic processor and optionally an energy source such as a battery, a rechargeable battery and/or a solar cell.
- the device can be reversibly connected to a container for the coolant, in particular liquid nitrogen.
- the container includes suitable means for sealingly connecting to the device to allow coolant to enter the cooling chamber.
- a suitable connection element can be provided on the container, which is connected to a suitable complementary connection element on the device, with a connection that is sealed off from the outside being created between the container and the device.
- the coolant container can be designed as a disposable container or advantageously as a reusable container.
- a coolant tank that is thermally insulated from the outside, e.g. in the form of a cartridge, is usually used.
- the supply of coolant from the coolant container into the cooling chamber takes place via the connection to the cooling chamber created when the container is attached to the device through an access opening in the cooling body.
- an access control element for the coolant between the coolant tank and the cooling chamber for example a controllable one valve, such as a ball valve.
- the access controller can be controlled on the basis of one or more variables selected from the temperature T1 of the beverage entering the drinking tube, the temperature T2 of the beverage leaving the drinking tube, the difference between T1 and T2, the flow rate of the beverage upon entry into the drinking tube, the temperature of the coolant inside the cooling chamber and/or the pressure of the coolant inside the cooling chamber. These variables can be determined by corresponding sensors on the drinking tube and/or in the cooling chamber.
- the coolant can exit the cooling chamber through an exit opening.
- the exit opening is formed separately from the entry opening.
- the exit port is formed integrally with the entry port, e.g., as a controllable three-way arrangement.
- a pressure reduction of the coolant exiting the cooling chamber is advantageously provided, e.g. by a pressure reduction valve.
- the device can also contain a controllable valve, such as a ball valve, in the drinking tube, which serves to control the flow rate of the beverage within the drinking tube.
- a controllable valve such as a ball valve
- a beverage in a container can be drawn through the drinking tube into the drinker's mouth, cooling quickly and efficiently to the desired temperature, typically 0-10°C.
- the device can be used to cool any drinks, e.g. alcoholic or non-alcoholic drinks.
- FIG 1 an embodiment of the device according to the invention is shown.
- the device contains a drinking tube with a lower section (10), a preferably curved, e.g. B. formed as a spiral central portion (12), for example made of stainless steel, and an upper portion (14).
- a Beverage (not shown) is taken up by the lower section (10), flows through the middle section (12), cooling taking place, and leaves the drinking tube (arrow direction) at the upper section (14) into the mouth of the drinker.
- the lower section (10) of the drinking tube is optionally at least partially provided with a lower lining (16).
- the upper section of the drinking tube (14) is optionally at least partially provided with an upper covering (18).
- the lower and upper panels can be made of a thermally insulating material, e.g. a thermally insulating plastic such as Teflon.
- the apparatus further includes a heat sink (20) having a cooling chamber (22) and an integral coolant inlet and outlet port (24) with a controllable three-way arrangement (not shown).
- An insulating element (28) is arranged around the heat sink (20) and comprises an insulating space (30) which is used for thermal insulation from the outside and is filled with air or a suitable insulating agent such as Tefzel.
- the device contains one or more sensors in the region of the lower end of the drinking tube, e.g. B. a temperature sensor (32) for measuring the temperature of the drink sucked into the drinking tube and/or a sensor for measuring the flow rate (34), e.g. an impeller sensor or an ultrasonic sensor.
- a pressure sensor (36) is provided to monitor the pressure of the coolant in the cooling chamber (22).
- the device also contains a control unit (38) and an energy source (not shown), such as a battery, an accumulator and/or a solar cell.
- an energy source such as a battery, an accumulator and/or a solar cell.
- a coolant container (40) When used as intended, a coolant container (40) is connected to the device, the coolant, z. B. contains liquid nitrogen. Conveniently, the coolant tank (40) is designed so that it reversibly attached to the device so that it can be removed after the coolant has been used up and replaced with a fresh container.
- a sealed connection (42) is provided between the coolant container (40) and the cooling chamber (22), which connection contains, for example, a ball valve (V) which can be controlled electronically in order to prevent the entry of coolant into the cooling chamber (20) and the exit from it To regulate coolant from the cooling chamber (20) as needed.
