Ice confectionery production equipment by rapid ice making and rapid ice melting

The present invention relates to an apparatus for producing ice confectionery by rapid ice making and rapid ice melting, and more specifically, an apparatus for producing ice confectionery by rapid ice making and rapid ice melting that can easily perform switching operation between ice making and ice melting with only one valve. About.

In general, when using various ice making devices such as refrigerators, various drinks such as commercially available fanta, cider or cola and juice, as well as various teas such as milk, coffee, cocoa, green tea, apples, pears Ice confectionery is made from juices of various fruits such as mandarin oranges, vegetable juices such as carrots and radishes. In some cases, a separate ice maker that can produce ice confectionery products is used in convenience stores and the like.

However, these types of ice making equipment and ice making machines are limited to the function of producing a sherbet-type product, so it is necessary to immediately produce ice cream and ice cake-type ice confections that require higher cooling. There was a problem.

In addition, in order to manufacture other types of ice confectionery products immediately after manufacturing one ice confectionery product, the container must be completely removed so that the taste of the previous ice confectionery product does not remain. There is a problem that it takes a considerable amount of time and labor to completely remove the ice confectionery residue adhering to the surface in a cooled state.

An ice confection manufacturing apparatus using rapid ice making and rapid ice thawing that can solve the problems of conventional ice making apparatuses and ice makers and that can immediately produce the required ice confectionery products is known (for example, Patent Document 1). As shown in FIG. 1, a compressor 11 and a condenser 13, an electronic valve 24 a, an expansion valve 14, and an evaporator 12 are sequentially connected and installed in the box-shaped case 25 by a refrigerant pipe. Between the refrigerant pipe connecting the condenser 13 and the refrigerant pipe connecting the condenser 13 and the evaporator 12, a bypass pipe 15 having an electronic valve 24 is connected and installed, and the evaporator 12 has a tray shape. A flat plate-shaped refrigerant pipe 22 is formed at the bottom of the evaporating dish 21 exposed at the top of the box-shaped case 25. A heat insulating material 23 covering the refrigerant pipe 22 was installed at the lower part of the refrigerant pipe 22 and the entire outer surface.

As shown in FIG. 2, as another embodiment of the evaporating dish used in the ice confectionery manufacturing apparatus, a refrigerant pipe 32 installed at the bottom of the evaporating dish 31 is formed integrally with the evaporating dish 31. The heat insulating material 33 is installed on the bottom. As shown in FIGS. 3 and 4, the refrigerant pipes 22 and 32 installed at the bottoms of the evaporating dishes 21 and 31 are formed with zigzag refrigerant channels or horizontal multi-tube refrigerant channels. Was installed.

Accordingly, when the compressor 11 is operated with the electronic valve 24 installed on the bypass pipe 15 closed at the same time and the electronic valve 24a on the expansion valve 14 side opened, the compressor 13, the electronic valve 24a, and the expansion The refrigerant that has passed through the valve 14 is supplied to the refrigerant pipes 22 and 32 of the evaporating dishes 21 and 31 that constitute the evaporator 12, and various drinks or materials such as fruit juice and vegetable juice are immediately frozen to obtain sherbet, ice cream, or ice cream. Ice confectionery such as cake can be produced, and the refrigerant used for producing ice confectionery is recovered by the compressor 11 and can be used for production of the next ice confectionery.

Further, when other types of ice confectionery are continuously manufactured in the process of manufacturing such ice confectionery, the electronic valve 24 installed on the bypass pipe 15 is opened simultaneously with closing the electronic valve 24a on the expansion valve 14 side. When the high-temperature refrigerant gas is supplied directly through the refrigerant pipes 22 and 32 of the evaporating dishes 21 and 31, the ice confectionery product remaining on the surface of the evaporating dishes 21 and 31 is quickly removed by the high-temperature refrigerant gas. It can be easily melted and removed. As a result, other types of ice confectionery products can be produced continuously in a short time, and at the same time, the tastes of the ice confectionery products can be prevented from mixing with each other.

Korean Patent No. 0430923 Specification

However, in the case of the ice confectionery manufacturing apparatus described above, one electronic valve 24, each on the refrigerant pipe provided with the bypass pipe 15 and the expansion valve 14 in order to selectively perform the ice making and ice melting operations. 24a is installed, and the expansion valve 14 and the electronic valve whose unit price is relatively expensive are used, so that the overall structure of the ice confectionery manufacturing apparatus becomes somewhat complicated, and at the same time, the unit manufacturing cost of the apparatus increases. There was a problem of letting. As a result, there is a problem that it is difficult to supply a cheaper ice confection manufacturing apparatus to an ice confectionery manufacturer that uses a small-scale sales method with a variety of small-quantity production.

In addition, when a switch (ON amp; OFF Switch) that individually operates each electronic valve 24, 24a is installed outside the box-shaped case 25, it is possible to determine the status of the corresponding switch during ice making and ice melting. There is a problem that the user needs to know exactly and operate the apparatus, which causes some confusion in the operation of the ice confectionery manufacturing apparatus. In order to prevent this, it is necessary to display on the case 25 a separate guidance display or design associated with the operation of the corresponding switch. However, for this purpose, additional costs are incurred, which is not desirable in terms of the unit manufacturing cost of the device. was there.

As another means for preventing the user's inconvenience and confusion associated with the operation of the ice confectionery manufacturing apparatus, each electronic valve 24, 24a can be controlled by a single switch. A separate electronic control component such as a printed circuit board (PCBP) is additionally installed between the electronic valves 24 and 24a, which is also not desirable from the viewpoint of the manufacturing cost of the apparatus.

In particular, when the ice confectionery manufacturing apparatus is operated in an ice-free state, the evaporating dishes 21 and 31 are heated in the process in which the high-temperature refrigerant gas discharged from the compressor 11 flows through the refrigerant pipes 22 and 32 of the evaporating dishes 21 and 31. At the same time, a part of the refrigerant gas is condensed in the high-temperature refrigerant gas, and liquid particles, that is, liquid refrigerant is generated in the refrigerant gas. An excessive amount of liquid refrigerant dilutes the working oil of the compressor 11, damages the bearings, and induces liquid compression inside the compressor 11. Therefore, there is a problem that the compressor 11 is damaged during operation of the ice confectionery manufacturing apparatus by applying a considerable load to the compressor 11.

In order to reduce the load on the compressor 11 due to the liquid compression phenomenon that occurs inside the compressor 11 as described above, the time for the ice-breaking operation by the compressor 11 to be formed as in the technical contents of the ice confectionery manufacturing apparatus is formed. It is possible to control the operation of the compressor 11 by installing a separate timer so as not to exceed a certain time, but this is also one factor that raises the manufacturing unit price of the confectionery manufacturing apparatus.

Therefore, the present invention has been made in view of such problems. The purpose of the present invention is to instantly freeze drinks, fruit juices, vegetable juices, and other materials in a tray-shaped evaporating dish, and sorbet or ice cream. Alternatively, an object of the present invention is to provide an ice confection manufacturing apparatus by rapid ice making and rapid ice melting capable of producing ice confectionery such as ice cake.

Further, in case of continuously manufacturing other types of ice confections are allowed to promptly heat the evaporating dish, dissolved easily remainder of the ice confection products with evaporation dish, quick ice-making and removing An object of the present invention is to provide an ice confectionery manufacturing apparatus by rapid ice melting.

In addition, the switching operation between ice making and ice melting can be easily performed with only one valve, the structure of the device is simplified, the manufacturing unit price is reduced, and the user can operate the device easily. An object of the present invention is to provide an ice confection manufacturing apparatus by rapid ice making and rapid ice melting that can effectively separate liquid particles in refrigerant gas reflowed into the compressor and prevent the compressor from being broken.

In order to solve the above problems, according to the aspect of the present invention, a compressor, a condenser, and an evaporator are installed inside a box-shaped case in a state of being connected by a refrigerant pipe, and a refrigerant that connects the compressor and the condenser is connected. A bypass pipe equipped with an electronic valve is connected between the pipe, the condenser and the refrigerant pipe connecting the evaporator. Form a refrigerant pipe. In addition, since heat insulating material covering the refrigerant pipe is installed on the lower and outer surfaces of the refrigerant pipe, the connection of the bypass pipe to the refrigerant pipe is transferred to the refrigerant pipe connecting the condenser and the evaporator. A capillary tube is integrally connected and installed along the refrigerant pipe at the position, and a liquid separator for separating liquid particles in the refrigerant gas flowing into the compressor is installed in the refrigerant pipe connecting the evaporator and the compressor. An ice confectionery manufacturing apparatus by ice making and rapid ice melting is provided.

As described above, according to the present invention, ice confectionery such as sherbet, ice cream, or ice cake can be manufactured by instantly freezing a material such as drink or fruit juice or vegetable juice in a tray-shaped evaporating dish. Further, in case of continuously manufacturing other types of ice confections are allowed to promptly heat the evaporating dish can be removed easily dissolved residue of ices product was attached to the evaporating dish.

In addition, the switching operation between ice making and ice melting can be easily performed with only one valve, which simplifies the structure of the device, lowers its manufacturing cost, and makes it easier for the user to operate. . In addition, by removing the liquid particles in the refrigerant gas re-flowing into the compressor after performing the de-icing operation, the compressor is prevented from malfunctioning, which greatly contributes to a reduction in the manufacturing cost of the equipment. .

Exemplary embodiments of the present invention will be described below in detail with reference to the accompanying drawings. In the present specification and drawings, components having substantially the same functional configuration are denoted by the same reference numerals, and redundant description is omitted.

FIG. 5 is a piping diagram showing an ice confectionery manufacturing apparatus according to the present invention. FIGS. 6A and 6B are partially enlarged views showing a desirable form of a capillary tube.

As shown in FIG. 5, the ice confectionery manufacturing apparatus by rapid ice making and rapid ice melting according to the present invention has a box-shaped case 25 in a state where the compressor 11, the condenser 13, and the evaporator 12 are connected by a refrigerant pipe. A bypass pipe 15 having an electronic valve 24 is connected between a refrigerant pipe connecting the compressor 11 and the condenser 13 and a refrigerant pipe connecting the condenser 13 and the evaporator 12. 12 has a tray shape, and a flat plate-shaped refrigerant pipe 22 is formed at the bottom of the evaporating dish 21 exposed at the top of the box-shaped case 25. The refrigerant pipe 22 is formed at the lower part of the refrigerant pipe 22 and the entire outer surface. A covering heat insulating material 23 is installed.

In addition, the evaporating dish can be formed integrally with the evaporating dish 31 at the bottom of the evaporating dish 31 (as shown in FIG. 2), as in the ice confectionery manufacturing apparatus previously filed. The structure of the flow path composed of the pipes 22 and 32 is similar to that of the previously filed ice confection manufacturing apparatus (as shown in FIGS. 3 and 4), and has a zigzag flow path and a horizontal multi-tube flow path. It can also be formed.

As a component corresponding to the main part of the present invention, a capillary pipe 26 having a diameter slightly smaller than the diameter of the corresponding refrigerant pipe is installed in the refrigerant pipe connecting the condenser 13 and the evaporator 12. Before the condensed refrigerant having decreased in temperature while passing through the condenser 13 from the compressor 11 is supplied through the evaporator 12, the condensed refrigerant is depressurized by using the pressure drop generated by the diameter difference with the refrigerant pipe. It serves to supply in a state. Therefore, compared with an electronic expansion valve, the structure is very simple and the price is reduced, and it is easy to install along the refrigerant pipe in one pipe form.

In addition, the depressurized state of the condensed refrigerant that has passed through the capillary 26 is very complicated and varied depending on the diameter of the capillary 26 and its shape, so the diameter of the capillary 26 matches the refrigerant discharge pressure due to the capacity of the compressor 11. Although it is desirable to select and use an appropriate capillary tube, it is possible to prevent excessive internal pressure from being applied to the refrigerant piping connecting the condenser 13 and the capillary tube 26, and at the same time, the mass flow rate of the refrigerant passing through the capillary tube 26 is used for producing ice confectionery. If possible, it is desirable to use a capillary of about 0.1 to 0.6 mm so that the flow rate is sufficient.

Further, as shown in FIGS. 6A and 6B, if the capillary 26 is bent in a spring shape or a wave shape and the passage time of the refrigerant is increased, the diameter of the capillary 26 is slightly larger than 0.6 mm. It doesn't matter. However, when the capillary tube 26 is installed in a straight line shape, a fine tube having a diameter of less than 0.1 mm should be used, and the position where the capillary tube 26 is installed is located between the capillary tube 26 and the refrigerant pipe during the deicing operation. Due to the pressure difference generated between them, the bypass pipe 15 must be in the transfer position where the bypass pipe 15 is connected to the refrigerant pipe so that the high-temperature refrigerant can naturally flow through the refrigerant pipes 22 and 32 of the evaporating dishes 21 and 31. .

And on the refrigerant | coolant piping which connects the compressor 11 with the evaporator 12, the liquid separator 27 for isolate | separating the liquid particle in the refrigerant gas which flows in from the compressor 11 is installed. The liquid separator 27 (Accumulator) acts as a storage tank that temporarily receives a mixture of oil and liquid refrigerant, and at the same time, the mixture of oil and liquid refrigerant flows through the compressor 11 at a safe rate with the refrigerant in the container state. Therefore, it is desirable to install it vertically as close to the suction side of the compressor 11 as possible.

Hereinafter, the operational relationship of the present invention formed as described above will be described in detail with reference to FIG.

First, when ice confectionery materials, that is, various drinks or fruit juices, vegetable juices, etc., are put into the evaporating dish 21, the electronic valve 24 installed in the bypass pipe 15 is closed and the compressor 11 is operated simultaneously. When the refrigerant flows from the compressor 11 along the refrigerant pipe of the refrigeration cycle formed by the condenser 13, the capillary tube 26 and the evaporator 12, the refrigerant 11 passes through the refrigerant pipe 22 of the evaporating dish 21 constituting the evaporator 12. At the same time as the refrigerant flows, the refrigerant evaporates while absorbing external heat, and the material contained in the evaporating dish 21 is rapidly made into ice.

That is, the refrigerant is supplied to the refrigerant pipe 22 of the evaporating dish 21 through the compressor 11, the condenser 13, and the capillary 26 that functions as an expansion valve, and then condensed in the circulation process of the refrigeration cycle that is re-flowed into the compressor 11. The condensing efficiency of the vessel 13 and the compression efficiency of the compressor 11 are maintained at the maximum, and rapid cooling in the evaporating dish 21 is enabled, whereby various ice confectionery materials placed in the evaporating dish 21 are immediately cooled. heat insulating material 23, which eaves refrigerant pipe 22 to block heat loss, to be manufactured promptly the ice confection, such as sherbets, ice cream or ice cakes.

When the ice confectionery material is put into the evaporating dish 21 formed in the tray shape as described above and the system of the present invention is operated, various ice confectionery materials are usually frozen within a few seconds while rapidly cooling, and sherbet or Ice cream or ice cake can be manufactured. If the ice making temperature of the material put into the evaporating dish 21, that is, the refrigerant evaporating temperature is maintained at about −30 ° C., the time required to complete ice making is about 10 seconds. Thin ice-shaped sherbet requires shorter ice making time, ice cream falls in the middle, and ice cake requires the longest time.

As described above, in order to manufacture an ice confection of a different type from the material put in the evaporating dish 21 during the ice making operation using the ice confection manufacturing apparatus according to the present invention, the evaporating dish is temporarily used. The residue of the ice confectionery product that has been frozen and adhered to the surface of 21 must be dissolved and removed. In this case, by opening the electronic valve 24 installed in the bypass pipe 15, the high-temperature refrigerant discharged from the compressor 11 flows directly through the refrigerant pipe 22 of the evaporating dish 21. This can be accomplished automatically through the capillary 26.

That is, when the electronic valve 24 installed in the bypass pipe 15 is opened, a part of the refrigerant discharged from the compressor 11 is supplied to the capillary tube 26 side through the condenser 13 and the rest passes through the bypass pipe 15. , Are supplied simultaneously to the refrigerant pipe 22 side and the capillary tube 26 side of the evaporating dish 21, but the condenser 13 only lowers the temperature of the refrigerant and has almost no change in the pressure state of the refrigerant. Although the pressure of the refrigerant is not greatly different, the diameter of the refrigerant pipe connected to the evaporator 12 is much larger than the diameter of the capillary 26 so that the refrigerant flowing through the capillary 26 receives a relatively large resistance. become. As a result, the refrigerant discharged from the compressor 11 can no longer flow through the capillary 26 and automatically flows through the refrigerant pipe 22 of the evaporating dish 21.

In addition, the refrigerant gas that flows in through the refrigerant pipe 22 of the evaporating dish 21 does not pass through the condenser 13 and the capillary tube 26 that functions as an expansion valve, so that the refrigerant gas is maintained in a high temperature and high pressure state. and allowed to temperature promptly rises evaporating dish 21. As a result, the residue of the ice confectionery product freeze-adhered to the evaporating dish 21 can be melted and removed very quickly. The refrigerant gas used for heating the evaporating dish 21 is discharged to the outside of the evaporator 12 in a partially condensed state, and then passes through a liquid separator 27 installed on the suction side of the compressor 11. , The liquid particles in the refrigerant gas are removed and then re-inflowed through the compressor 11.

After removing the remaining ice confectionery product adhering to the evaporating dish 21 as described above, the electronic valve 24 installed in the bypass pipe 15 is closed as described above, and the apparatus returns to the first refrigeration cycle. At the same time, another type of ice confectionery can be newly put into the evaporating dish 21 for ice making. As a result, the taste of the freshly made ice confectionery product is not mixed with the taste of the previously produced ice confectionery product, and the desired flavored ice confectionery product can be produced.

As described above, the ice confectionery manufacturing apparatus according to the present invention is formed by the compressor 11, the condenser 13, the capillary 26 and the evaporator 12 in a state where various drinks or materials such as fruit juice and vegetable juice are put in the tray-shaped evaporation dish 21. By using the refrigeration cycle, it is possible to easily produce various ice confections such as sherbet, ice cream or ice cake, and to continuously produce other types of ice confectionery. is it opens the electronic valve 24 installed in the bypass pipe 15 can be removed by dissolving easily remainder of the ice confection products having adhered to the evaporation dish 21 by causing promptly heat the evaporation dish 21 . This prevents the taste of previously produced ice confectionery products from being mixed with the taste of newly produced ice confectionery products.

The ice confectionery manufacturing apparatus according to the present invention is different from the previously filed ice confectionery manufacturing apparatus in that a capillary tube 26 having a simple structure is installed in the refrigerant pipe connecting the condenser 13 and the evaporator 12. Makes it possible to perform the roles of expansion valve and electronic valve at the same time, greatly simplifying the overall structure of the ice confectionery manufacturing equipment. Moreover, the unit price of the ice confectionery manufacturing apparatus can be reduced by not using the expansion valve and the electronic valve corresponding to the electronic valve. As a result, it is possible to supply a cheaper ice confectionery manufacturing apparatus to an ice confectionery manufacturer or the like that performs a small-scale sales method by small-lot production.

Further, the ice making and defrosting operations by the ice confectionery manufacturing apparatus can be easily accomplished by using only one electronic valve 24. Thus, if only one switch for operating the electronic valve 24 is installed outside the box-shaped case 25, the user can easily operate the apparatus without being confused by the ice making state switch OFF state and the deicing state switch ON state. Can be operated. Further, there is no need to display a separate guidance display or design associated with the operation of the corresponding switch on the box-shaped case 25, and it is not necessary to install a separate electronic control component between the switch and the electronic valve 24. It also contributes to lower unit prices.

In particular, the high-temperature refrigerant gas discharged from the compressor 11 during the ice-breaking operation by the apparatus heats the evaporating dish 21, and at the same time, a part of the high-temperature refrigerant gas is condensed, so that liquid particles, that is, liquid Even if the refrigerant is generated, the liquid separator 27 installed on the suction side of the compressor 11 mixes the liquid refrigerant in a state where the liquid particles are removed, or the liquid refrigerant in an appropriate ratio that does not apply a load to the compressor 11. It is possible to prevent the breakdown of the compressor 11 by flowing the body refrigerant into the compressor 11. As a result, it is not necessary to install a separate timer for controlling the operation time of the compressor 11 as in the prior application, which can further contribute to the reduction in the manufacturing cost of the apparatus.

Although the above-described content is a typical embodiment in which one evaporating dish 21 is installed in the box-shaped case 25, the box-shaped case 25 is similar to the technical content of the previously filed ice confectionery manufacturing apparatus. A parallel refrigeration cycle in which each evaporating dish 21 shares one compressor 11 and condenser 13 by using a plurality of evaporating dishes 21 facing each other and using another capillary tube 26 and an electronic valve 24. It is obvious that it is a technical matter obvious to those who have ordinary knowledge in the technical field to which the present invention belongs.

As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. It is obvious that a person skilled in the art can conceive various changes or modifications within the scope described in the claims for utility model registration, and these naturally belong to the technical scope of the present invention. It is understood.

The present invention can be applied to an ice confectionery manufacturing apparatus using rapid ice making and rapid ice melting.
