Description

Apparatus for manufacturing ice cream by rapid deicing and rapid thawing {Device for manufacturing forzen sweet by a Quick Freezing and Melting}

The present invention relates to a frozen dessert manufacturing apparatus by rapid deicing and rapid thawing, and more particularly, such as beverages, fruit juices, vegetable juices, etc., are immediately frozen in a tray-type evaporating dish, such as sherbet, ice cream, and ice cake. When the ice cream is produced and other types of ice cream are continuously produced, the ice cream by rapid ice making and quick thawing enables the evaporating dish to be heated immediately to make it easy to dissolve and remove the residues of the frozen product on the evaporating dish. It relates to a manufacturing apparatus.

In general, when an ice maker such as a refrigerator is used, various beverages such as fanta, cider, cola, juice, etc., as well as various kinds of tea such as milk, coffee, cocoa, green tea, and various fruits such as apples, pears, and oranges are ground. Grinded vegetables such as things, carrots, and radishes can be produced in the form of ice.

In some cases, separate ice makers are used to produce ice cream products at a certain commercial scale in convenience stores, but are limited to the function of producing a sherbet-type product. That is, it is difficult to produce in the form of ice cream or ice cake that requires higher cooling than this.

In addition, to manufacture another kind of product immediately after the manufacture of one ice cream product, the residues in the container must be removed to prevent the mixing of the flavors, which requires considerable time and effort to remove the cooled residues. Hyepyeong 2-29576 (published Jan. 31, 1990) is known as a water-flow ice maker used for a bending machine (vending machine), and the water-flow ice maker is connected to a compressor via a condenser and an expansion valve, and is connected in parallel to an evaporator pipe through an electronic valve. Hot air bypass is installed between the discharge side of the compressor and the inlet side of the evaporator pipe, and the hot air bypass pipe is installed on the inlet side of the condenser, and the bottom side of a small grain freezing plate installed in the bending machine (vending machine). The bottom of the ice tray and the partition wall by passing the hot air to both the evaporator pipe and the heat engine Ice ice is applied to the ice from both sides of the bulkhead surface to separate the ice frozen in the ice-making unit into each ice compartment unit to separate the small particles of ice to prevent bridges of the ice particles. It is known to drop and drop cold beverages. However, as an oil-type ice maker used in the above-mentioned banding machines, it is not possible to make small grains of ice in ice-making units or to thaw iced ice. However, there was a problem that can not produce ice cream using drinks, fruit juice, vegetable juice and the like.

In order to solve the above problems, the present invention freezes frozen beverages, fruit juices, vegetable juices, etc. by using an evaporating dish on the fly to make frozen dessert products, and when you want to make different kinds of frozen desserts in succession, heating the evaporating dish to evaporate dishes. The technical task is to allow the frozen ice residues to be easily dissolved and removed so that the taste of the frozen ice cream does not mix with the previously produced ice cream.

In order to solve the above technical problem, the present invention comprises a compressor, a condenser, an expansion valve, and an evaporator are sequentially connected by a refrigerant passage, and a solenoid valve is installed in the refrigerant passage connected between the condenser and the expansion valve. And a refrigeration cycle in which a bypass tube having a solenoid valve is connected between the inlet tube side of the condenser connected to the discharge tube side of the compressor and the inlet tube side of the refrigerant pipe.

BRIEF DESCRIPTION OF THE DRAWINGS The schematic diagram which shows schematic structure of the principal part of the apparatus which concerns on this invention is shown.

The present invention relates to a refrigeration apparatus using a refrigeration cycle in which the compressor (11), the evaporator (12), the condenser (13), and the expansion valve (14) are sequentially connected by a refrigerant passage (not shown). We propose a compact structure cooling device for easy installation and use in a place.

To this end, the present invention is provided with a solenoid valve 24a in the refrigerant passage connected between the condenser 13 and the expansion valve 14, the inlet tube side of the condenser 13 connected to the discharge tube side of the compressor (11) The bypass pipe 15 having the solenoid valve 24 is connected between the inlet pipe side and the inlet pipe side of the refrigerant pipe 22. A case 25 having a housing shape surrounding the entire exterior of each of the above components is provided. The evaporator 12 is installed so that the refrigerant pipe 22 is formed flat in the form of a flat plate, and is located above the case 25. The evaporator 12 has a tray-shaped evaporation plate on the upper surface of the refrigerant pipe 22. (22) is installed to be exposed to the upper portion of the case 25, the heat insulating material 23 surrounding the refrigerant pipe 22 is provided on the lower portion and the outside of the refrigerant pipe 22. The present invention is another embodiment. For example, the evaporating plate 21 and the refrigerant pipe 22 are integrally formed. In addition, the refrigerant passage has a configuration in which another solenoid valve 24a, the solenoid valve 24, the expansion valve 14, and the evaporation plate 21 are provided on a plurality of parallel passages. Refrigerant pipe 22 according to the function having the function of the evaporator 12 is formed flat in the form of a plate, wound in a spiral form is molded in a state that maintains the entire plane. Accordingly, the outer end and the center of the refrigerant pipe 22 are respectively connected to the circulation of the refrigerant. The cross section of the refrigerant pipe 22 is preferably as flat as possible to maximize the contact area for heat transfer.

In addition, according to the present invention, the upper surface of the evaporating plate 21 which can be opened and closed accommodates the refrigerant pipe 22 on the bottom surface, the upper surface of the evaporating plate 21 to install the cover to keep the product cool and to prevent foreign substances from entering The refrigerant pipe 22 is provided intimately on the bottom surface of the evaporating plate 21 via a heat insulating material 23.

Referring to the functional relationship of the present invention configured as described above is as follows. When the ice cream material is to be defrosted after the ice cream material in the evaporation plate 21, the refrigerant along the refrigerant flow path of the refrigeration cycle The solenoid valve 24 installed in the bypass pipe 15 is closed to circulate through the compressor 11, the condenser 13, the expansion valve 14, and the refrigerant pipe 22 of the evaporator 12, and the condenser 13 ) And the solenoid valve 24a of the refrigerant flow path connected between the expansion valve 14 to open the refrigerant.

That is, the refrigerant circulates in the flow path in the order of the compressor 11 → condenser 13 → solenoid valve 24 → expansion valve 14 → refrigerant pipe 22 → compressor 11 of the evaporator 12. During this time, the condensation efficiency of the condenser 13 and the compression efficiency of the compressor 11 are maintained to the maximum, so that rapid cooling is possible in the evaporation plate 21, and the frozen material placed on the evaporation plate 21 is immediately cooled, and the refrigerant pipe The heat insulating material 23 which fully covers 22 is in close contact with the bottom surface of the evaporating dish 21 to block heat loss, thereby quickly producing ice creams such as sherbet, ice cream, and ice cake. After removing one kind of ice cream from the evaporation plate 21 and buried in the evaporation plate 21 to make another kind of ice cream. In order to thaw the residue, the solenoid valve 24a installed in the refrigerant flow path between the condenser 13 and the expansion valve 14 of the refrigeration cycle is closed and the solenoid valve 24 of the bypass pipe 15 is closed. Open so that the refrigerant is circulated to the refrigerant pipe 22 of the compressor 11 and the evaporator 12.

That is, when the solenoid valve 24a of the refrigerant flow path connected between the condenser 13 and the expansion valve 14 is closed, and the solenoid valve 24 provided in the bypass pipe 15 is opened, the refrigerant is supplied to the compressor 11. The refrigerant efficiency of the refrigerant is reduced by circulating the refrigerant pipe 22 of the evaporator 12 without passing through the condenser 13 and the expansion valve 14, which causes the temperature of the evaporation plate 21 to rise and evaporates to a high temperature. Since the dish 21 is heated and the residue of the frozen fruit buried in the evaporating plate 21 is melted, the user can easily remove the remaining residue by burying in the evaporating plate 21 to remove other kinds of frozen fruit from the evaporating plate ( By making fresh ice in 21), the taste of the frozen ice cream can be produced so that the taste of the frozen ice cream is not mixed with each other.

In this way, when the material is put into the evaporating plate 21 formed in the form of a tray and the system of the present invention is operated, various kinds of materials are quenched and frozen in a predetermined time (usually several seconds) to produce sherbet, ice cream, ice cream, and the like. For reference, if the ice making temperature of the material introduced into the evaporation plate 21 is maintained at about -30 ° C, the de-icing completion time takes about 10 seconds.

Such sherbet, ice cream, ice cream can be manufactured by adjusting the time to freeze, because the sherbet is frozen like frozen ice is made by cooling in the shortest time, the ice cream is in the middle, ice cream is required the longest time.

Figure 2 is a block diagram showing another example of the evaporating plate according to the present invention, Figures 3 and 4 is a schematic diagram showing an exemplary flow path structure of the refrigerant pipe installed in the lower portion of the evaporating plate of FIG.

The above-described evaporation plate 21 and the refrigerant pipe 22 may be formed integrally, and FIGS. 2 to 4 show examples of the evaporation plate 31 and the refrigerant pipe 32. In this case, the refrigerant pipe 32 is a moldability is easy to select the zigzag flow path as shown in Figs. 3 and 4 rather than a spiral flow path, Figure 3 is a series circuit form and Figure 4 is a parallel circuit form of the refrigerant The connector for circulation is formed at both ends.

According to such a configuration, it is not necessary to process a separate pipe in a spiral form and the attachment of the insulator 33 is easy, so that the production cost can be lowered. Is increased.

5 is a schematic diagram showing a main part configuration of a mechanism according to a modification of the present invention.

The evaporation plate 21 of the present invention may be configured to be installed separately on a plurality of parallel flow paths, although not shown, the configuration of the bypass pipe 15 and the refrigerant pipe 22 may be described with reference to FIGS. 1 to 4. And the expansion valve 14 and the solenoid valve 24 (24a) and the like are configured on the same parallel circuit and its working relationship is also the same as above.

At this time, according to the present invention to change the flow direction of the refrigerant as the solenoid valve 24 (24a) for the thawing of the residue remaining on the evaporation plate 21 as described above, the temperature rise in the evaporation plate 21 It further has a function of causing.

In order to make ice products by freezing all of the above ingredients in one or more evaporating dishes 21 and to make ice products as other ingredients to other guests, the residues frozen in the evaporating dishes 21 are melted (thawed) and wiped off. Later, the other ingredients will be frozen again to make different ice products.

To this end, during freezing (de-icing), the refrigerant is circulated through the refrigerant pipe 22 of the compressor 11 → condenser 13 → expansion valve 14 → evaporator 12 to cool the material introduced into the evaporation plate. In order to make ice products and to make other ice products, the refrigerant is circulated through the refrigerant pipe 22 of the compressor 11 and the evaporator 12, and the evaporation plate 22 is heated to dissolve and wipe off the residues on the evaporation plate. Will.

At this time, the flow path of the refrigerating cycle is made by the operation of the solenoid valves 24 and 24a, and the operation of these solenoid valves 24 and 24a uses a method in which a solenoid is mounted and electrically controlled. When the user presses only the switch for thawing, the user automatically switches to the thawing mode so that the evaporation plate 21 is heated (heated).

In any case, however, the thawing function may reduce the efficiency and durability of the cooling device, and therefore, it is preferable not to operate the timer relay continuously for more than a predetermined time.

On the other hand, as shown in Figure 4, when the evaporation plate 21 is two, it may be cooled in two at a time and only frozen one by one, melting is more convenient because it can melt only one side or both sides at the same time.

According to the above constitution and action, the present invention freezes the ingredients such as beverages, fruit juices, and vegetable juices in an evaporating dish in the form of trays to make ice creams such as sherbet, ice cream, and ice cakes, During manufacture, the evaporating dish can be heated immediately to dissolve the residues of the frozen dessert product on the evaporating dish, thereby easily dissolving drinks, fruits, vegetables, etc. in the form of ice cream on the fly, and different kinds of frozen ice When prepared by the effect that does not mix.
