Abstract

The present invention provides an ice candy mold cooling device which has a high cooling efficiency and does not care about the structure of the mold unit. In this frozen candy mold cooling device, supply pipe accommodating portions are provided at lower portions of both long sides of a brine tank, and in-bath supply pipes are installed in the supply pipe accommodating portions. This allows the brine discharge pipe to be positioned below all the molds of the mold unit. Also, the brine discharge pipe can be brought closer to the mold without considering the height of the air vent. Furthermore, the guide plate of this ice-candy mold cooling device is bent upward at a substantially right angle so that the low-temperature brine ejected from the ejection port is ejected directly upward. As a result, regardless of the structure of the mold unit, this ice mold cooling device has a significantly higher cooling capacity than conventional ones, and even if the number of manufacturing equipment installed on the upstream side and the installation area increase, the mold unit conveying speed can be reduced. It is possible to manufacture frozen desserts without delaying the production process. [Selection drawing] Fig. 3

TECHNICAL FIELD The present invention relates to an ice candy mold cooling apparatus for cooling a mold filled with ice candy material to produce ice candy such as ice candy.

2. Description of the Related Art As an apparatus for producing ice candy such as ice candy, an ice candy mold cooling apparatus called a so-called bitter line is widely used. This frozen candy mold cooling device called a bitter line has a plurality of molds M, which serve as molds for frozen candy, fixed in the lateral direction, for example, the mold units 3a and 3b shown in FIG. It is a device that continuously manufactures ice-candies by filling ice-candy materials and inserting sticks while sequentially moving them. The representative mold units 3a and 3b used in the ice mold cooling apparatus are arranged in a row as shown in the front view of FIGS. 1(a) and (b) and the top view of FIG. 1(c). It mainly consists of a mold plate 5 having an opening 6 and fixing portions 7 to a conveying chain 42, which will be described later, at both ends, and a mold M whose upper edge is fixed to the opening 6 and serves as a mold for ice candy. Among them, the mold unit 3b shown in FIG. 1(b) has a rod-like or plate-like reinforcing member 4 that connects the lower part of the mold M. As shown in FIG.

The inventors of the present application have made an invention described in [Patent Document 1] below with respect to such an ice candy mold cooling device. Here, FIG. 5 is a top view showing the brine tank portion of the conventional ice mold cooling device 10 shown in [Patent Document 1]. 6 is a partial schematic cross-sectional view of the conventional ice mold cooling apparatus 10 taken along the line Xa--Xa in FIG. 5 in the short side direction, and FIG. 1 is a partial schematic sectional view in a direction; FIG.

The conventional ice mold cooling apparatus 10 shown in FIGS. 5 to 7 includes a brine tank 20' for storing low-temperature brine, a brine collection tank 30' for collecting brine overflowing from the brine tank 20', and a mold. A conveying unit that holds both ends of the units 3a and 3b and conveys the mold M in the long side direction while being immersed in the brine tank 20', a brine supply pipe 25a' that supplies brine to the brine tank 20', and the brine supply. In-tank supply pipes 25b' connected to the pipes 25a' and installed at the lower portions of both long sides of the brine tank 20', and a plurality of brine discharge pipes 50' connected so as to span between the in-tank supply pipes 25b'. , a plurality of discharge ports 26 provided on the side surface of the brine discharge pipe 50' for discharging brine, and a guide plate 27 having a substantially inverted V shape that directs the brine discharged from the discharge ports 26 upward toward the mold M. ' and have.

Next, using FIG. 8, a brief description will be given of the procedure for producing ice candy with different tastes (ice material) on the surface and inside using the conventional ice mold cooling apparatus 10. FIG. 2 to 9, the molding units 3a, 3b and the conveying chain 42 in the brine tanks 20, 20' are partially omitted. Further, the upper side and the front side here mean the upper side (upstream side) with respect to the advancing direction of the mold units 3a and 3b, and the lower side and the rear side refer to the lower side in the advancing direction of the mold units 3a and 3b. means (downstream).

First, in the case of producing ice candy with different ice candy materials on the surface layer and inside, a first filling device 12a for filling the first ice candy material and the inside of the mold M a second filling device 12b for filling a second ice candy material; and a stick inserter 14 for inserting a stick serving as a handle of the ice candy into the mold M. , are placed at least. Further, on the downstream side of the brine tank 20, there is a defrosting device 16 as recovery equipment for warming the mold M pulled up from the brine tank 20 and partially melting the outside of the ice candy, and a stick is sandwiched to remove the ice candy from the inside of the mold M. At least an extraction device 17 for extraction is arranged.

In the brine tank 20' of the ice-candy mold cooling device 10, brine cooled to a predetermined temperature by a brine cooling device (not shown) flows through a brine supply pipe 25a', an in-bath supply pipe 25b', and a brine discharge pipe 50'. supplied. Further, drive gears 44 are provided in front of and behind the brine tank 20' as a transport section, and a transport chain 42 is stretched between the drive gears 44 along both long sides of the brine tank 20'. Then, the mold units 3a and 3b are fixed so as to bridge between the two transport chains 42 located on the left and right sides. When the driving gear 44 rotates, the conveying chain 42 moves, and the mold units 3a and 3b move from the upstream side to the downstream side of the brine tank 20' accordingly.

Then, when the mold units 3a and 3b reach the operating position of the first filling device 12a, the first filling device 12a injects a predetermined amount of the first ice-candy material into each mold M to form the surface layer of the ice-candy. The poured first ice material is cooled by the brine in the brine bath 20' and gradually freezes from the outside in contact with the mold M. Then, when the thickness of the frozen layer of the first ice candy material in the mold M reaches approximately the target thickness, the mold units 3a and 3b reach the operation position of the suction device 13. As shown in FIG. When the mold units 3a, 3b reach the operating position of the suction device 13, the suction device 13 inserts a nozzle into each mold M to suction out the unfrozen first ice material inside. The molding units 3a, 3b are then moved into the operating position of the second filling device 12b. Then, the second filling device 12b injects a predetermined amount of the second ice-candy material (constituting the inside of the ice-candy) inside the frozen layer of the first ice-candy material. This second ice material is cooled and gradually frozen while the mold units 3a, 3b travel through the brine bath 20'. The mold units 3a and 3b reach the operation position of the stick interserter 14 when the second ice candy material reaches a predetermined semi-frozen state. When the mold units 3a and 3b reach the operating position of the stick interserter 14, the stick interserter 14 inserts a stick as a handle of the ice candy into the semi-frozen second ice candy material. The mold units 3a, 3b then proceed through the remaining brine bath 20' until the second ice candy material is completely frozen.

Then, when the ice candy material in the mold M is completely frozen and the mold units 3a and 3b reach the vicinity of the end of the brine tank 20', the conveying chain 42 is gradually lifted, whereby the mold units 3a and 3b are brought into the brine. It is pulled up from the bath 20 . Then, the mold M is warmed by the defrosting device 16, and the contact portion between the ice candy and the mold M melts. Next, the extracting device 17 clamps the stick inserted into the ice candy material and extracts the ice candy from the mold M together with the ice candy. This completes the ice dessert. The mold units 3a and 3b from which the ice candy has been pulled out are reversed by the rear driving gear 44, washed by the mold cleaning section 18, and after being reversed again by the front driving gear 44, are fed again to manufacture the ice candy. be.

Thus, a plurality of manufacturing facilities are installed on the upstream side of the brine tank 20'. In the case of manufacturing a complex ice candy having a particularly large number of layers, the number of manufacturing facilities to be installed increases, and the installation area of the manufacturing facilities occupies a large area of the brine tank 20'. In such a case, the freezing area on the downstream side is shortened, and there is a risk that the freezing of the ice candy material will not be completed in time even at the end of the brine tank 20' at the normal transport speed, and the product will not be completely frozen. For this reason, it is necessary to slow down the conveying speed of the mold units 3a and 3b as a whole, and there is a problem that the productivity deteriorates.

To address this problem, the inventors of the present application have made an invention described in [Patent Document 2] below. As shown in FIGS. 9(a) to 9(c), the ice candy mold cooling device 10A described in [Patent Document 2] has a brine discharge wall 80 having a discharge port 82 on the wall surface of the brine discharge portion on the downstream side. and the mold M is passed between the brine discharge walls 80 . As a result, when the mold M passes between the brine discharge walls 80, low-temperature brine is sprayed from the left and right brine discharge walls 80 at a close distance, and is rapidly cooled.

As described above, the ice mold cooling device 10A described in [Patent Document 2] is capable of rapid cooling by the brine discharge wall 80, so that the ice candy material can be completely frozen in a short time even if the distance is short. As a result, even if the number of manufacturing equipment installed on the upstream side or the installation area increases, it is possible to manufacture frozen desserts without slowing down the conveying speed of the mold unit.

An embodiment of an ice candy mold cooling device 100 according to the present invention will be described with reference to the drawings. It should be noted that the same reference numerals are used for the same configuration as the conventional device. Here, FIG. 2 is a top view showing the brine tank portion of the ice mold cooling apparatus 100 according to the present invention. 3 is a partial cross-sectional view of the ice mold cooling apparatus 100 according to the present invention taken along the line Xb--Xb in FIG. 2 in the short side direction, and FIG. It is a partial schematic cross-sectional view in the long side direction.

First, like the conventional ice mold cooling apparatus 10, the ice mold cooling apparatus 100 according to the present invention includes a long brine tank 20 for storing low-temperature brine and a brine recovery for collecting brine overflowing from the brine tank 20. a tank 30, a conveying unit that holds both ends of the mold units 3a and 3b and conveys the mold M in the long side direction while being immersed in the brine tank 20, a brine supply pipe 25a that supplies brine to the brine tank 20, and the In-tank supply pipes 25b connected to the brine supply pipes 25a and installed at the lower portions of both long sides of the brine tank 20, and a plurality of brine discharge pipes 50 connected so as to bridge between the in-tank supply pipes 25b on both left and right sides. A plurality of discharge ports 26 provided on the side surface of the brine discharge pipe 50 for discharging the brine supplied from the brine supply pipe 25a into the brine tank 20, and the discharged brine installed in the discharge direction of the discharge port 26. and a guide plate 27 directed upward toward the mold M side.

The conveying section of the ice mold cooling apparatus 100 holds the mold units 3a and 3b and conveys them while being immersed in the brine tank 20, as in the conventional ice mold cooling apparatus 10. , drive gears 44 provided in front of and behind the brine tank 20 for rotating the transport chains 42, and rotating means such as a motor (not shown) for rotating the drive gears 44. is doing. The mold units 3a and 3b are fixed so as to span between the left and right conveying chains 42 via the fixing portions 7 at both ends. Further, when the drive gear 44 rotates, the conveying chain 42 moves between the front and rear drive gears 44 . The transport chain 42 is lowered at the front end and raised at the rear end by tension rollers or guides (not shown) provided at the front and rear ends of the brine tank 20 . As a result, the mold units 3a and 3b held by the conveying chain 42 are lowered at the front end of the brine tank 20 so that the molds M are immersed in the brine, move in the brine tank 20 as they are, and are immersed in the brine at the rear end. It is pulled up from the bath 20 . Then, the ice mold cooling apparatus 100 is sequentially moved to the operating positions of the respective manufacturing equipment and collecting equipment.

Next, the characteristic structure of the ice-candy mold cooling device 100 according to the present invention will be described in comparison with the conventional ice-candy mold cooling device 10 . First, the brine tank 20 of the ice mold cooling apparatus 100 is a long tank with a length of about ten and several meters. As shown in the schematic cross-sectional view of FIG. It has a supply pipe accommodating portion 22 protruding in the direction. In the ice mold cooling apparatus 100 according to the present invention, the in-vessel supply pipes 25b installed at the lower portions of both long sides of the brine tank 20' in the conventional ice mold cooling apparatus 10 are replaced with the supply pipe accommodating portions 22. Install. In addition, the brine discharge pipe 50 of the present invention is connected so as to bridge between the left and right in-vessel supply pipes 25b housed in the supply pipe housing portion 22. As shown in FIG. Therefore, the brine discharge pipe 50 of the present invention is longer than the brine discharge pipe 50' of the conventional ice mold cooling device 10, and has a length substantially equal to the width of the top opening of the brine tank 20.

Here, the conventional ice mold cooling apparatus 10 does not have the supply pipe accommodating portion 22, and the in-bath supply pipes 25b' are simply placed under both long sides of the brine tank 20' as shown in FIGS. had been installed. Therefore, the molds M outside the mold units 3a and 3b (the third molds M from the left and right ends in FIGS. 5 and 6) move above the in-vessel supply pipe 25b' having no discharge port 26. As a result, there is a difference in the cooling rate between the inner mold M and the freezing state of the ice candy material may vary, especially when cooling is performed in a short time.

However, in the ice mold cooling apparatus 100 according to the present invention, since the in-bath supply pipe 25b is installed in the supply pipe accommodating portion 22 as described above, the in-bath supply pipe 25b is placed from the movement path of the mold units 3a and 3b. It is out of the moving range of the mold units 3a and 3b. Also, the brine discharge pipe 50 has a length substantially equal to the width of the top opening of the brine tank 20, and as shown in FIGS. 50 will be located. As a result, low-temperature brine is sprayed onto the mold M under the same conditions, and it is possible to prevent variations in the frozen state depending on the location.

Moreover, in the ice mold cooling device, there are cases where a part of the discharge ports 26 are closed in order to adjust the cooling capacity. At this time, in the conventional ice mold cooling apparatus 10, there are no outlets 26 in the in-tank supply pipes 25b' on both sides, and flow rate cannot be adjusted by blocking the outlets 26 on both sides. However, in the ice mold cooling apparatus 100 according to the present invention, since the discharge ports 26 are present all under the movement area of the mold units 3a and 3b, the flow rate is adjusted by closing the discharge ports 26 at the central portion and the side portions. It can be done under the same conditions. As a result, even when adjusting the flow rate by closing the discharge port 26, it is possible to prevent variations in the frozen state depending on the location.

In addition, a plurality of air vent holes 28 are provided on the upper surfaces of the in-vessel supply pipes 25b and 25b' for discharging air caught in the brine to the outside. As described above, in the conventional ice mold cooling apparatus 10, the molds M pass above the in-bath supply pipe 25b', so the air discharged from the air vent 28 may also affect the variation in the frozen state. There was However, in the ice mold cooling apparatus 100 according to the present invention, since the in-bath supply pipe 25b is accommodated in the supply pipe accommodating portion 22, the air released from the air vent hole 28 is discharged from the ceiling of the supply pipe accommodating portion 22 into the brine tank. It is discharged outside through the edge of 20 . Therefore, the released air does not adversely affect the cooling of the mold M. The ceiling surface of the supply pipe accommodating portion 22 should be a sloped surface with a higher inner side (body side of the brine tank 20) so that the air discharged from the air vent hole 28 can quickly flow to the brine tank 20 side without stopping. is preferred.

In addition, since the air vent holes 28 usually protrude slightly from the in-tank supply pipes 25b and 25b', a sufficient clearance is provided in the conventional ice mold cooling apparatus 10 so that the molds M passing above do not contact the air vent holes 28. I needed it. Therefore, in order to bring the brine discharge pipe 50 closer to the mold M, it is necessary to change the design such as bending the pipe, which cannot be easily performed.

However, in the ice-candy mold cooling device 100 according to the present invention, since the air vent 28 is provided in the supply pipe accommodating portion 22, there is no need to consider the height of the air vent 28. FIG. Therefore, the brine discharge pipe 50 can be brought closer to the mold M by simply raising the position of the brine discharge pipe 50 . As a result, the ice mold cooling device 100 according to the present invention can spray the low-temperature brine to the mold M at a position closer than that of the conventional ice mold cooling device 10, and a higher cooling capacity than the conventional one can be obtained. can.

Furthermore, in the ice mold cooling apparatus 100 according to the present invention, the brine supply pipe 25a', which is conventionally drawn from the bottom surface of the brine tank 20', is connected to the in-tank supply pipe 25b from the side of the supply pipe housing portion 22. Thereby, the bottom of the brine tank 20 can be raised, and the volume of the brine tank 20 can be reduced. As a result, the increase in the capacity of the brine tank 20 due to the formation of the supply pipe accommodating portion 22 can be offset and further reduced. By reducing the amount of brine used, the brine cooling cost can be reduced.

The brine recovery tank 30 of the ice-candy mold cooling apparatus 100 according to the present invention has a lower portion that protrudes outward corresponding to the projection of the supply pipe accommodating portion 22, and has a substantially crank shape when viewed in cross section. Thereby, the capacity of the brine recovery tank 30 can be maintained at an appropriate value.

Further, the guide plate 27 of the ice mold cooling apparatus 100 according to the present invention is different from the guide plate 27' of the conventional ice mold cooling apparatus 10, which has a substantially inverted V-shape, as shown in FIG. is bent at a substantially right angle to the As a result, the low-temperature brine ejected from the discharge port 26 is ejected directly upward by the guide plate 27, and can be ejected onto the mold M at a shorter distance. As a result, the ice mold cooling apparatus 100 according to the present invention can obtain a significantly higher cooling capacity than the conventional one due to the close arrangement of the brine discharge pipe 50 and the substantially right-angled guide plate 27 .

Next, the operation of the ice candy mold cooling device 100 according to the present invention will be described. First, in the same way as in the conventional apparatus, a production facility and a recovery facility for producing the desired frozen dessert are installed. In addition, the mold units 3a and 3b corresponding to the ice candy to be produced are fixed so as to span the left and right conveying chains 42 of the ice candy mold cooling device 100. As shown in FIG. It should be noted that regardless of the presence or absence of the reinforcing member 4, any of the mold units 3a and 3b can be used in the ice mold cooling apparatus 100 according to the present invention. In the brine tank 20, brine cooled to a predetermined temperature of about -30°C to -36°C by a brine cooling device (generally a calcium chloride solution is used) is supplied to a brine supply pipe 25a and an intra-tank supply pipe. 25b, the brine discharge pipe 50, and the discharge port 26, and is maintained at a prescribed water level or in a full water state. Normally, the in-tank supply pipe 25b is provided separately on the upper side and the lower side. It is common to connect each individually.

Next, the transport section of the ice mold cooling apparatus 100 is operated. As a result, the driving gear 44 rotates and the conveying chain 42 moves between the front and rear driving gears 44 . As the conveying chain 42 moves, the mold units 3a and 3b also move. Then, the molds M of the mold units 3a and 3b are immersed in the low-temperature brine stored in the brine tank 20. As shown in FIG. At this time, excess brine overflowing from the brine tank 20 falls into a brine recovery tank 30 installed on the outer periphery of the brine tank 20, and is returned to the brine cooling device via the brine recovery tank and the brine return pipe. The returned brine is cooled again to a predetermined temperature by the brine cooling device, and then supplied to the brine tank 20 through the brine supply pipe 25a, the in-bath supply pipe 25b, and the like.

Further, when the mold units 3a and 3b reach the operating positions of the respective manufacturing equipment, injection and suction of ice candy materials, insertion of sticks, and the like are performed. Since these operations are performed while the mold M is immersed in the brine tank 20, the ice candy material poured into the mold M is cooled and frozen by the low-temperature brine in the brine tank 20. At this time, in the ice candy mold cooling device 100 according to the present invention, the brine discharge pipe 50 is arranged close to and below all the molds M of the mold units 3a and 3b, and the guide plate 27 is arranged from the brine discharge pipe 50. Since the spouted low-temperature brine is directed directly upward and sprayed onto the mold M at a shorter distance, the cooling efficiency is higher than that of the conventional ice-candy mold cooling device 10, and cooling and freezing of the ice-candy material can be performed in a short period of time. can. It should be noted that the upstream side of the brine tank 20 in which each manufacturing equipment is installed may be required to be cooled relatively slowly. In this case, the cooling capacity on the upstream side can be adjusted by lowering the flow rate of the brine supply pipe 25a on the upstream side. Also, by closing some of the outlets 26 and adjusting the number of operating outlets 26, the cooling capacity on the upstream side can be adjusted.

When the operation by each manufacturing equipment is completed, the mold units 3a and 3b are moved to the lower side, and the ice-candy material in the mold M is rapidly cooled by the high cooling capacity of the ice-candy mold cooling apparatus 100 according to the present invention. . The mold units 3a and 3b with frozen ice candy materials are pulled up at the end of the brine tank 20, and the defrosting device 16 melts the contact portion between the mold M and the ice candy. Then, the stick is clamped by the extraction device 17 and extracted from the mold M to complete the frozen dessert. The finished ice candy is sent to the next step and subjected to appropriate processing such as packaging. Further, the mold units 3a and 3b from which the ice-candies have been removed are washed by the mold cleaning unit 18, and then supplied to manufacture the ice-candies again.

As described above, the ice candy mold cooling apparatus 100 according to the present invention is provided with the supply pipe accommodating portions 22 under both long sides of the brine tank 20, and the in-bath supply pipes 25b are installed in the supply pipe accommodating portions 22. As shown in FIG. Then, the brine discharge pipe 50 is extended to a length substantially equal to the width of the top opening of the brine bath 20, and positioned below all the molds M of the mold units 3a and 3b. As a result, it is possible to prevent variations in the frozen state depending on the location of the mold units 3a and 3b. Further, the flow rate adjustment by closing the discharge port 26 can be performed under the same conditions in the central portion and the side portion of the mold units 3a and 3b.

In addition, in the ice mold cooling apparatus 100 according to the present invention, since the in-bath supply pipe 25b is located in the supply pipe accommodating portion 22, there is no need to consider the height of the air vent hole 28, and the position of the brine discharge pipe 50 is simply determined. The brine discharge pipe 50 can be brought closer to the mold M by raising it. As a result, it becomes possible to spray the low-temperature brine to the mold M at a close position, and a higher cooling capacity than in the past can be obtained.

Further, in the ice candy mold cooling apparatus 100 according to the present invention, the brine supply pipe 25a is connected from the side of the supply pipe accommodating portion 22 to the in-bath supply pipe 25b. Thereby, the bottom of the brine tank 20 can be raised, and the volume of the brine tank 20 can be reduced. Thereby, the cooling cost of the brine can be reduced.

Furthermore, the guide plate 27 of the ice-candy mold cooling apparatus 100 according to the present invention is bent upward at a substantially right angle, and the low-temperature brine ejected from the discharge port 26 is ejected directly upward. As a result, the low-temperature brine can be sprayed onto the mold M at a shorter distance than before. The ice mold cooling apparatus 100 according to the present invention is much more efficient than the conventional one, regardless of the structure of the mold unit, due to the lengthening and close arrangement of the brine discharge pipe 50 and the nearly right-angled guide plate 27 . High cooling capacity can be obtained. As a result, the cooling efficiency of the mold M is improved, and even if the number of manufacturing equipment installed on the upstream side or the installation area increases, the ice candy can be manufactured without slowing down the transport speed of the mold unit.

The configuration, shape, number, operation mechanism, piping route, design, etc. of the ice mold cooling device 100, the brine tank 20, the brine recovery tank 30, the brine discharge pipe 50, and other parts shown in this example are examples. The present invention can be modified and implemented without departing from the gist of the present invention.
