Description

  The present invention relates to a cooling device for storing a beverage in a beverage container in a supercooled state.

  Generally, a liquid undergoes a phase transition from a liquid phase to a solid phase at a freezing point, but does not cause a phase transition even at a temperature below the freezing point, and may remain in a liquid state, that is, a supercooled state. The supercooled liquid is energetically metastable, but instantaneously transitions to the solid phase due to external stimuli. A beverage supercooling cooling device capable of instantly freezing a beverage in a sherbet shape by pouring into a glass at the time of drinking or applying vibration by utilizing this characteristic is disclosed in, for example, JP-A-10-9739. (Patent Document 1) and JP-A-2003-214753 (Patent Document 2).

  The conventional supercooling cooling device disclosed in Japanese Patent Application Laid-Open No. 10-9739 (patent document 1) inputs initial temperature, quantity and take-out time when storing a beverage, and stores them in advance based on those values. By cooling the beverage with the temperature control pattern, the beverage in an overcooled state is provided.

  Moreover, the conventional cooling device for supercooling disclosed in Japanese Patent Application Laid-Open No. 2003-214753 (Patent Document 2) makes the flow of cold air in the device substantially uniform by arranging ducts and fans, and the beverage is evenly distributed. By cooling to a uniform temperature distribution, a supercooled beverage is provided.

  If cooling is performed so that the temperature distribution becomes uniform at an appropriate cooling rate, the liquid can be kept in a supercooled state. Theoretically, even if the water has a freezing point of 0 ° C., it is a minus number in degrees Celsius. The supercooled state can be maintained at 10 degrees.

  As described above, the supercooled liquid is energetically metastable, but the energy barrier to the most stable solid phase is the difference between the supercooled liquid temperature and the freezing point (degree of supercooling). It gets lower as it gets bigger.

  In other words, the larger the degree of supercooling of the liquid, the easier it is to release and freeze the supercooling with a smaller stimulus. In addition, instantaneous freezing is less likely to occur.

  In addition, since the freezing point varies depending on the beverage type, the beverage may freeze at the same beverage temperature even when it is taken out from the cooling device or during cooling, or may not freeze even when a stimulus such as vibration is applied.

In other words, there is a temperature range suitable for supercooled storage for each beverage type to be cooled. The upper limit temperature is a freezing point of the beverage, and the lower limit temperature is considered to be a temperature at which the supercooled state is released with a slight stimulus or a temperature at which the beverage is likely to freeze during cooling.
JP-A-10-9739 JP 2003-214753 A

  However, with the conventional supercooling cooling device described above, it is impossible to determine the storage temperature for maintaining the supercooling, and it is only possible to set the temperature based on the user's experience.

  FIG. 7 shows a flowchart for calculating the temperature at which the beverage container is stored by the storage temperature calculation processing unit 31. FIG. 8 shows a flowchart for determining a storage room for storing a beverage container by the storage room determination processing unit 32.

  First, as shown in FIG. 7, the calculation process of the storage temperature of a drink is demonstrated. The user reads the information of the beverage in the beverage container by holding the barcode described in the beverage container to be stored over the barcode reader 4 (step S1). The read information is first collated with the data stored in the internal database 28 (step S2).

  If there is no matching data, the external data communication unit 63 (step S3) collates with the external database (step S4). If there is matching data, the information is read into the internal database 28, Information is updated (step S5). On the other hand, if there is no matching data in the external database, the data output monitor 2 is notified that there is no matching data (step S6), and then the concentration of at least one of the sugar concentration and the alcohol concentration of the beverage to be stored. The user inputs (calculation density) (step S7) and updates the internal database (step S5).

When the collation between the stored beverage data and the data stored in the internal database 28 is completed, the freezing point _Tf of the beverage is read from the internal database 28 (step S8).

  Here, the data stored in the internal database 28 and the external database will be mentioned. In this database, in addition to distribution information such as barcodes, corresponding manufacturer codes, and product codes, alcohol content and sugar concentration are stored in a list. The freezing point of the beverage is automatically calculated in the database from the sugar concentration and alcohol concentration of the beverage. When information is newly input into the database, the manufacturer code, product code, sugar concentration, and alcohol concentration may be input. The reason for this will be described in detail below. Since the sugar concentration and alcohol concentration are mostly described in the beverage container, the user can also input them by themselves.

  A method for calculating the storage temperature will be described below. In order to maintain supercooling, it is necessary to cool at least below the freezing point of the beverage. Specifically, it is desirable to cool to a range of about (freezing point−2 ° C.) to (freezing point−10 ° C.). In order to determine the storage temperature, it is first necessary to clarify the freezing point of the beverage. It is most desirable to actually measure the freezing point for each beverage, but it is practically impossible to measure the freezing point for all of the beverages that are distributed. Therefore, it is necessary to estimate the freezing point by some method.

Beverages are aqueous solutions in which water is the main component (solvent), and sugar, carbon dioxide, minerals, alcohol, pigment components, etc. (solutes) are dissolved in water. Below the freezing point of 0 ° C. (freezing point depression). The freezing point depression does not depend on the type of solute dissolved, but depends on the molar concentration of the solute (number of moles of solute dissolved per kg of solvent). The magnitude ΔT _f [K] of the molar freezing point depression is expressed by the following equation (1).
ΔT _f = (M _s RT _m ² / H _m ) × Σm _i Formula (1)

Here, R is a gas constant [J / mol · K], T _m is a freezing point [K] of the solvent, H _m is a heat of solidification (heat of fusion) [J / mol] of the solvent, and M _S is a molecular weight of the solvent [g / mol], _{m i} is the molality of the solute i [mol / kg], Σm i represents the sum of the molar concentration of all solutes.

Since R = 8.31 J / mol · K and the main component (solvent) of the beverage is water, T _m = 273 K (0 ° C.), H _m = 6.0 kJ / mol, and using formula (1), If the molar concentration of the dissolved solute is known, the freezing point T _f = −ΔT _{f of the} beverage can be estimated. If the freezing point _{Tf of the} beverage is known, the set temperature T can be determined by T = _Tf − _Tc , where _Tc is the temperature to cool below the freezing point, that is, the degree of supercooling. As described above, _Tc is preferably in the range of about 2 ° C to 10 ° C.

  Various substances that cause freezing point depression are dissolved in beverages, and are mainly classified into proteins, carbohydrates, carbohydrates, lipids, and alcohols. Approximate molecular weights are as follows: protein (high polymer of amino acid, polymer): thousands to g / mol, carbohydrate (high polymer of sugar, polymer): tens of thousands to millions of g / mol, carbohydrate (Sucrose): 342 g / mol, lipid: hundreds to thousands g / mol, alcohol (ethanol): 46 g / mol.

Here, when the molecular weight of a solute dissolved in 1 kg of beverage is M _i [g / mol] and the weight is x _i [g], the molar concentration _mi (mol / kg) is m _i = x _i / M _i , which is inversely proportional to the molecular weight of the solute. Since the order of the amount dissolved in the actual beverage is the same for all ingredients, the contribution of protein, carbohydrate, and lipid to the freezing point depression of the large molecular weight is smaller than that of sugar, alcohol, which has a small molecular weight. Ignore small. Therefore, the freezing point may be estimated from the sugar and alcohol concentrations.

  Using formula (1), the theoretical freezing point when alcohol (ethanol) and sugar (sucrose) are dissolved in water is calculated as shown in [Table 1] below.

※エタノール Ｃ_２Ｈ_６Ｏ ４６ｇ／ｍｏｌ
ショ糖 Ｃ_１２Ｈ_２２Ｏ_１１ ３４２ｇ／ｍｏｌ [Table 1]

* Ethanol C ₂ H ₆ O 46g / mol
Sucrose C ₁₂ H ₂₂ O ₁₁ 342 g / mol

In summary, the calculation formula of the freezing point _Tf of the beverage is the following formula (2). In the database, the set temperature of each beverage is automatically calculated using Equation (2).
T _f = − (M _s RT _m ² / H _m ) × (m _sugar + m _alcohol ) Formula (2)

Hereinafter, the description returns to the flowchart. After reading the freezing point _Tf from the database (step S8), the supercooling degree _Tc is set (step S9). The user can select whether the supercooling degree _Tc is set automatically or manually. The automatic setting value of the degree of supercooling _Tc is preferably about 2 ° C.

When manual setting is selected, the user inputs a value of the degree of supercooling _Tc from the data input panel 3 (step S10). At this time, it is determined whether the _Tc input value is greater than 0 ° C. and is equal to or less than the maximum supercooling degree _{Tc, max} set in the apparatus (step S11). The maximum degree of supercooling _{Tc, max} is preferably about 10 ° C. If the condition is not satisfied, an error is displayed on the data output monitor 2 and the user is again input the degree of supercooling _Tc (step S12). By the above operation, the supercooled storage temperature T = _Tf − _{Tc of} the beverage to be stored is determined (step S13).

  After calculating the temperature which preserve | saves the said beverage container, as shown in FIG. 8, it transfers to the process which determines the storage chamber which accommodates a beverage container.

First, the current set temperature T _i (i = 1, 2, 3,... N) of each storage room (i = 1, 2, 3,... N) is a temperature sensor installed in each room. Is measured. Then, the storage temperature T of the supercooling calculated beverage, determines whether each storage room set temperature T _i at the present time coincides (step S21).

  Here, if there is a room (storage room) that satisfies the above conditions, the corresponding room number is displayed on the data output monitor 2 (step S22), the user stores the beverage container (step S23), and the temperature control process is performed. Move.

  If there is no room that satisfies the condition in the determination, it is determined whether or not the temperature of each storage room is within the allowable temperature range for supercooled storage of the beverage to be stored (step S24).

As described above, in order to store under cooling, it is necessary to store under cooling so that the degree of overcooling is about 2 ° C. to 10 ° C., but the storage temperature can be widened. Therefore, the temperature determination of the storage chamber, by using the above settings subcooling _{T c,} the maximum degree of supercooling _{T c,} the _{max, T f -T c, max} ≦ T i ≦ T f -T c (i = 1, 2, 3,... N), if the current set temperature T _i of the storage chamber i satisfies the conditional expression, it can be stored in the general i room, and if the conditional expression is not satisfied, the general temperature i It can be determined that room storage is not possible. The above condition determination is performed for all the storage rooms (i = 1, 2, 3,..., N).

In addition, if there is a room satisfying the above condition, the room closest to the storage temperature T for the supercooling of the beverage is determined (step S25). That is, the room in which the absolute value of the difference between the storage room set temperature _Ti and the beverage storage temperature T is minimized is determined. Then, the room number is displayed on the data output monitor 2 (step S26), the user stores the beverage container (step S23), and the process proceeds to the temperature control process.

If there is no room satisfying the allowable temperature determination, the data output monitor 2 displays the content without the proper greenhouse (step S27), and allows the user to select the room whose temperature is to be changed (step S28). the set temperature _{T i,} and change in the temperature T calculated at storage temperature calculation process ₍₌ T f -T _{c) (step} S29), shifts to the temperature control process.

  According to the cooling device having the above configuration, the control unit 27 calculates and determines the storage temperature of the storage chambers 11, 12, and 13 from the calculation concentration of the beverage in the beverage container, and stores the storage temperature. Since the beverage is stored in a supercooled state at a temperature, the temperature that could only be determined on a trial basis can be automatically determined in the device, and failure to maintain supercooling can be greatly reduced. The operability is greatly improved.

  Therefore, the storage temperature suitable for supercooling can be automatically determined according to the beverage to be stored, the beverage can be cooled to the supercooled state more reliably, and the operability is greatly improved. .
