Close 60B (FIG. 4).

By closing the heat insulating doors 60A and 60B, the sealing materials 70 and 70 are in close contact with each other and the gasket G is in close contact with the opening edge of the heat insulating box 55, so that the front opening of the heat insulating box 55 is sealed. It In this case, since the cuts are formed in the horizontal direction in the sealing members 70, 70 at the positions corresponding to the front of the centers of the closed containers 53A, 53B, 53C as described above, the heat insulating doors 60A, 60B are closed. But
The hoses 16A, 16B, 16C connected to the respective closed containers 53A, 53B, 53C can face the front from between the seal members 70, 70. The sealing materials 70, 70 are in close contact with the periphery of the hoses 16A, 16B, 16C, and the sealing materials 70, 70 are in intimate contact with each other to seal between the heat insulating doors 60A, 60B in other portions.

Further, the heat insulating doors 60A and 60B are of a double door type, and even if the three hoses 16A to 16C are present in the central portion so as to project forward, both heat insulating doors 60A and 60B are provided.
Since it can be opened so as to be divided into left and right, there is no hindrance in its opening and closing, and the heat insulating doors 60A and 60B can be opened as shown in FIG. Since the heat insulating box 55 is also opened in the opening direction of each closed container 53A to 53C, the source container 5
It is easy to pay 4 points.

The inside of the heat insulating box 55 is a cooling pipe P.
Since it is cooled to a predetermined refrigerating temperature by 3, the sauce in the sauce container 54 ... Is also kept cold at a refrigerating temperature close to the temperature of the soft serve ice cream via the wall surface in each closed container 53A to 53C. As a result, it is possible to avoid the inconvenience that the soft ice cream is melted by the temperature when the sauce is topped on the soft ice cream (frozen dessert) as described later.

When the source container 54 is replaced, the reverse operation described above may be performed. With this structure, the source container 54 is exchangeably housed in the closed container 53A. With the above configuration, the structure required for pressure control and sealing can be simplified as compared with the case where the source container 54 is directly housed in the heat insulating box 55 and pressure is applied to the entire heat insulating box 55, and the closed container 53A is provided. ~ 53C compared with the case where the cooling pipe P3 is attached to itself, the replaceability is improved in the case where a failure occurs in the closed containers 53A to 53C whose internal pressure is high, and the application of air pressure to the source container 54 and the source are generally improved. Both of the cooling can be realized smoothly.

Further, with the above-mentioned structure, the lid member 5
7, source extraction port member 59, hose 16A (16B, 1)
6C) and the source container 54 can all be disassembled,
Cleaning and replacement of each member is extremely easy.

Next, the piping path 84 between the air compressor 51 of the source pressure feeding device 2 and each of the closed containers 53A to 53C will be described. A check valve 87 is connected to the discharge pipe 86 of the air compressor 51.
After going through 7, it is branched into three directions. The branch pipe 89A is inserted into the heat insulating box 55 through the through hole 111 through the source 1 air supply valve (electromagnetic valve) 88A, is connected to the air supply pipe 67 of the closed container 53A, and is branched. Similarly, 89B is communicatively connected to the air supply pipe 67 of the closed container 53B via a source 2 air supply valve (electromagnetic valve) 88B, and the branch pipe 89C is similarly connected via a source 3 air supply valve (electromagnetic valve) 88C. It is communicatively connected to the air supply pipe 67 of 53C.

The check valve 87 is the source 1 air supply valve 88.
The directions of A, the source 2 air supply valve 88B and the source 3 air supply valve 88C are the forward direction. In addition, branch pipes 89A, 89
Exhaust pipes 91A, 91B, and 91C are attached to B and 89C, respectively, and a source 1 exhaust valve (solenoid valve) 92A, a source 2 exhaust valve 92B, and exhaust pipes 91A to 91C, respectively.

B, 89C. Further, 72 is a main pressure sensor for detecting the air pressure on the discharge side of the air compressor 51 (downstream of the check valve 87).

The air compressor 51 is operated to compress the air and discharge it to the discharge pipe 86. Source 1 Air supply valve 8
8A, the source 2 air supply valve 88B, and the source 3 air supply valve 88C are open, the compressed air discharged from the air compressor 51 is branched via the check valve 87 to branch pipes 89A to 89.
It is supplied from C into the respective closed containers 53A to 53C. The supply of the compressed air increases the air pressure in the closed containers 53A to 53C, and applies pressure to the source containers 54 from the surroundings. As a result, the sauce in the sauce container 54 is pushed out from the sauce extraction port member 59 to the hoses 16A to 16C.

Further, by controlling the opening and closing of the air supply valves 88A to 88C, the supply of compressed air to the closed containers 53A to 53C can be independently controlled. Furthermore, each exhaust valve 92A
Up to 92C, the air in the closed containers 53A to 53C can be exhausted to the outside by exhaust pipes 91A to 91C, respectively.

Next, FIG. 8 shows a front view of the operation panel 22. The operation panel 22 is a panel for displaying the operation state of the source pressure feeding device 2 and setting the amount of the source to be extracted from the source container 54 in each closed container 53A to 53C of the source pressure feeding device 2.

Next, FIG. 9 shows a control device C of the frozen dessert making apparatus 1.
The block diagram of is shown. Although the control device C also controls the frozen dessert manufacturing and extraction of the entire frozen dessert manufacturing device 1,
Here, only the part relating to the control of the source pressure feeding device 2 is shown. The control device C is composed of a microcomputer 107. The input of the microcomputer 107 is the operation panel 22 and the pressure sensors 93A to 93.

-OFF control is performed, and lighting of each LED of the operation panel 22 is controlled.

In this case, when the air compressor ON relay 51CR is turned on and off, the air compressor 5
1 is run-stopped. Further, when the air compressor water removal relay 51LR is turned on and off, the water removal device of the air compressor 51 is turned on and off. Further, when the source 1 air supply valve relay 88AR is turned on and off, the source 1 air supply valve 88A is opened and closed, and when the source 1 exhaust valve relay 92AR is turned on and off, the source 1 exhaust valve 92A is opened and closed.

The operation of the frozen dessert making apparatus 1 of the present invention having the above configuration will be described. The liquid soft ice cream mix is stored in the hopper 6. Then, as described above, this liquid soft ice cream mix is introduced into the cooling cylinder 8 and cooled by stirring with the beater 7 to produce a semi-cured soft ice cream. Then, in the case of extracting the soft serve ice cream that does not have the sauce topping, if the rightmost lever is pulled down to move the plunger 12D upward, the plunger 12D is separated from the through hole 18 of the ejection nozzle 4B as described above, and The rightmost outlet of the extraction passage 14 is also opened. Further, since the soft serve extraction switch 44D is turned ON via the arm 42D by the elevation of the plunger 12D, the control device C drives the beater motor 9 to rotate the beater 7.

As a result, the semi-cured soft ice cream in the cooling cylinder 8 is pushed forward, and the extraction passage 1
4 through the extraction passage 11D, and the through hole 1 of the extraction nozzle 4B.
It is extracted through 8. In this way, soft ice cream (frozen desserts) that is not topped by pumping the sauce
Will be extracted from the extraction nozzle 4B via the extraction passage 11D located on the rightmost side.

Next, the operation of the source pressure feeding device 2 of the frozen dessert manufacturing apparatus 1 will be described with reference to the control sequence diagram of FIG. In the following description, the case of extracting the source from the closed container 53A will be described, but another closed container 53 will be described.
The same applies to B and 53C.

(1) Normal Operation (Preparation) As described above, assuming that the source container 54 is housed in the closed container 53A and the lid member 57 is closed, the source 1 lid switch 66A is in the ON state. . In this state, press the source 1 switch 96 on the operation panel 22 (O
N) and the controller C are the air compressor ON relay 5
1CR and source 1 air supply valve relay 88AR is turned on, air compressor 51 is operated, and source 1 air supply valve 8
Open 8A. In addition, always source 1 exhaust valve relay 92AR
Is off, and the source 1 exhaust valve 92A is closed. Further, the source valve 36 corresponding to the plunger 12A is also lowered to close the introduction passage 24.

As a result, the compressed air discharged from the air compressor 51 is supplied into the closed container 53A through the discharge pipe 86, the check valve 87, the source 1 air supply valve 88A, the branch pipe 89A and the air supply pipe 67. The air pressure (indicated by source 1 pressure (Mpa) in FIG. 10) in the closed container 53A rises. At this time, the control device C displays the operation panel 22.
By blinking the red and green chips of the source 1 LED 101 and blinking orange, the user is informed that the source container 54 (source 1) in the closed container 53A is being prepared for extraction.

When the pressure in the closed container 53A rises to a set value, for example, 0.2 MPa, the controller C
Judges that the air pressure in the closed container 53A has risen to the set value based on the output of the source 1 pressure sensor 93A, and the air compressor ON relay 51CR and the source 1
The air supply valve relay 88AR is turned off, the air compressor 51 is stopped, and the source 1 air supply valve 88A is closed.
At this point, preparation for extracting the source from the source container 54 of the closed container 53A is completed, and the control device C sets the source 1LED1
The user is informed that the source extraction possible state is switched by switching 01 to orange continuous lighting.

When the volume of the source container 54 is reduced by the following source extraction operation, the air pressure in the closed container 53A is lowered (see FIG. 10). Then, the air pressure inside the closed container 53A is 0.18 Mpa (hysteresis 0.02 Mp), which is a lower limit value lower than the set value (0.2 Mpa).
When the pressure is reduced to a), the control device C turns on the air compressor ON relay 51CR and the source 1 air supply valve relay 88AR again based on the output of the source 1 pressure sensor 93A to operate the air compressor 51 and the source 1 Open the air supply valve 88A. When the air pressure in the closed container 53A rises to the set value, the air compressor ON relay 51CR and the source 1 air supply valve relay 88AR
Is turned off, the air compressor 51 is stopped, and the source 1 air supply valve 88A is closed. As a result, the control device C maintains the air pressure in the closed container 53A at a (substantially) constant value in the range of 0.2 Mpa to 0.18 Mpa, which is the set value, and controls the air pressure applied to the source container 54 to the set value. is doing.

(2) Normal operation (extraction) When the leftmost lever 13A is pulled down to move the plunger 12A upward, as described above, the plunger 12A is separated from the through hole 31 of the star adapter 19, and The leftmost outlet of the extraction passage 14 is also opened. Further, since the soft serve extraction switch 44A and the sauce 1 take-out switch 46A are turned ON via the arm 42A by the elevation of the plunger 12A, the control device C drives the beater motor 9 to rotate the beater 7.

As a result, the semi-cured soft ice cream in the cooling cylinder 8 is pushed forward and the extraction passage 1
4 enters the extraction passage 11A and is extracted via the through hole 31 of the star adapter 19 on the leftmost side of the extraction nozzle 4A.

On the other hand, since the connecting arm 38 of the leftmost source valve 36 is engaged with the engaging groove 39 of the plunger 12A, the source valve 36 moves up as the plunger 12A moves up. When the source valve 36 rises, the introduction passage 24 is opened as described above, so that the source container 54 in the closed container 53A and the leftmost introduction passage 24 of the extraction nozzle 4A are opened via the hose 16A and the source extraction port member 59.
Are communicated.

As a result, the source container 54 housed in the closed container 53A is pressed by the air pressure in the closed container 53A, and the inside source is opened at the rear end of the source extraction port member 59 and the communication hole 83 on the side surface. -Is pushed out into the source extraction port member 59, passes through the hose 16A, and enters the extraction nozzle 4A. The source that has entered the take-out nozzle 4A reaches the annular passage 23 from the leftmost introduction passage 24, is split into left and right there, and is then discharged from the outlets 32 and 32.

As a result, the sauce is continuously added (topping) to the peripheral portion along the flow of the soft serve ice cream extracted from the extraction passage 11A through the through hole 31 of the star-shaped adapter 19, A unique sauce pattern is formed on the surface of the extracted soft serve ice cream, which enhances the willingness to purchase and allows customers to enjoy the unique flavor of strawberry jam from the beginning to the end of eating.

When the extraction is completed, the lever 13A is pushed up and the plunger 12A is pulled down. As a result, the plunger 12A closes the leftmost outlet of the extraction passage 14 and the through hole 3 of the star-shaped adapter 19.
Since it comes into close contact with 1, the extraction of soft cream is stopped. In addition, the soft ice cream extraction switch 44A and the sauce 1 take-out switch 46A are also OF through the arm 42A.
Since it is F, the control device C stops the beater motor 9. Further, since the source valve 36 is also pulled down as the plunger 12A is lowered, the leftmost inlet passage 24 in the take-out nozzle 4A is closed, whereby the addition (topping) of the source is also stopped. Further, the source valve 36 closes the introduction passage 24, so that the leakage of the source from the outlet 32 is prevented.

(3) Normal Operation (Adjustment of Source Amount) The amount of sauce extracted from each closed container 53A to 53C (the amount of sauce extracted during one extraction of soft serve ice cream, or the amount of sauce per fixed time) When adjusting the extraction amount), the setting switch 94 of the operation panel 22 is pushed. When the setting switch 94 is pressed, the control device C first turns on the source 1 LED 101 in green,
While the source amount is being adjusted is displayed (source 2
The LED 102 and the source 3 LED 103 are turned off), and the source amount setting display 106 displays the current set value corresponding to the source (source 1) of the source container 54 in the closed container 53A by the number of lit LEDs.

For example, assuming that the source amount in the case of air pressure in the closed container 53A having the set value of 0.2 Mpa is a standard value, this standard value is, for example, the source amount setting indicator 1.
It is displayed by lighting three LEDs 06 from the left. Then, for example, when increasing the source amount, pressing the right arrow button of the source amount adjusting switch 99 causes LE
One more D will light up. Then, the set value of the air pressure in the closed container 53A is increased by one step (for example, a predetermined pressure of 0.04 MPa). This allows the sauce container 5
Since the air pressure applied to 4 increases, the pressing force increases and the extraction amount increases. On the contrary, when the source amount is to be reduced, pressing the left arrow button of the source amount adjusting switch 99 reduces one LED. Then, the set value of the air pressure in the closed container 53A is lowered by one step. As a result, the air pressure applied to the source container 54 becomes low, so that the pressing force also becomes weak and the extraction amount decreases (the hysteresis is the same). In this way, the set value of the air pressure in the closed container 53A can be set to an arbitrary value within a certain range.

When the setting switch 94 is pressed twice, the control device C turns on the source 2 LED 102 in green (the source 1 LED 101 and the source 3 LED 103 are turned off).
The source amount setting display 106 displays the current set value corresponding to the source (source 2) of the source container 54 in the closed container 53B by the number of lit LEDs. Then, similarly, the source amount adjustment switch 99 can adjust the source amount. When the setting switch 94 is pressed three times, the control device C turns on the source 3LED 103 in green (source 1L
The ED 101 and the source 2 LED 102 are turned off), and the source amount setting display 106 displays the current set value corresponding to the source (source 3) of the source container 54 in the closed container 53C by the number of lit LEDs. Then, similarly, the source amount can be adjusted by the source amount adjusting switch 99.

(4) Normal Operation (Opening the Lid) Here, during such normal operation, for example, the closed container 53A is used.
When the stopper 58 is lifted, that is, when the lid member 57 of the closed container 53A is about to be opened, the protrusion 65 of the stopper 58 is separated from the source 1 lid switch 66A and the contact of the switch 66A is opened (OFF). To be done. When the source 1 cover switch 66A is turned off, the control device C turns on the source 1 exhaust valve relay 92AR to open the source 1 exhaust valve 92A. Also, source 1LED1
01 is flashed in red to notify the user of the opening of the source 1 exhaust valve 92A, and the operation of the air compressor 51 and the opening of the source 1 supply valve 88A are prohibited.

As a result, the inside of the closed container 53A is communicated with the outside through the exhaust pipe 91A and the source 1 exhaust valve 92A, so that the compressed air in the closed container 53A is removed and the air pressure rapidly drops to atmospheric pressure. . Therefore, the inconvenience that the lid member 57 pops out due to the air pressure in the closed container 53A when the stopper 58 is removed is eliminated. When the stopper 58 is pulled down again and the stopper 1 lid switch 66A is turned on, the control device C restarts the above-mentioned extraction preparation operation and raises the air pressure in the closed container 53A to the set value. .

(5) Normal operation (sold out) The sauce in the sauce container 54 gradually decreases due to the extraction of the sauce accompanying the extraction of the soft serve ice cream (frozen dessert). Then, when the source in the source container 54 disappears, the volume of the source container 54 does not decrease any more, so the plunger 12A is pulled down, the source valve 36 rises, and the source 1 take-out switch 46A is turned on and sealed. The air pressure in the container 53A does not decrease (stops changing).

Based on the output of the source 1 pressure sensor 93A, the controller C does not change the air pressure in the closed container 53A for a certain period after the source 1 take-out switch 46A is turned on, or changes the pressure per predetermined time. If the amount is smaller than a certain value (threshold value), the closed container 53A
It is determined that the source (source 1) in the source container 54 of 1 is finished, that is, sold out.

When the controller C makes such a sold-out judgment, the source 1 exhaust valve relay 92AR is turned on to turn on the source 1.
The exhaust valve 92A is opened, and the air in the closed container 53A is discharged to bring the pressure to the atmospheric pressure as described above. And the source 1L
The user is notified of the end of the source by blinking the ED 101 in red. In this way, since the end of the sauce is judged according to the pressure change in the closed container 53A, it is not necessary to attach a special sensor or switch for detecting the sold-out or count the number of sold pieces.

Here, when the amount of sauce in the source container 54 decreases, the bottom surface of the source container 54 eventually contacts the rear end opening of the source extraction port member 59 and closes it. However, the expanded portion 82 of the source extraction port member 59
The rear end of the source container 5 enters the interior of the source container 54 beyond the neck portion 54A and projects inward, and the communication hole 83 is also located inside the source container 54 relative to the neck portion 54A.
Even if the bottom surface of 4 closes the rear end opening of the source extraction port member 59, the communication hole 83 on the side surface is not closed and a space inside the source container 54 is secured around it.

As a result, the sauce container 54 is further crushed and the bottom surface is brought into close contact with the base portion of the neck portion 54A, and the sauce in the sauce container 54 is pushed out until the communication hole 83 is closed. Thus, the amount of sauce remaining in the sauce container 54 is minimized. Therefore,
It is possible to reduce costs by effectively using the source.

(6) Source Replacement Operation When the source in the source container 54 of the closed container 53A is completed in this way, the completed source container 54 is replaced with a new source container 54. In that case,
First, open the heat insulation doors 60A and 60B of the heat insulation box 55,
The stopper 58 of the closed container 53A is lifted and held horizontally above the container body 56 as shown in FIG. This allows
The protrusion 65 of the stopper 58 is the source 1 lid switch 66A.
The contact of the source 1 cover switch 66A is opened (OFF) while being separated from. The control device C uses this lid switch 66A
It is determined that the lid member 57 is opened by turning OFF.
Next, the user presses the source 1 switch 96.

When the source 1 switch 96 is pressed while the source 1 cover switch 66A is off, the controller C turns on the air compressor ON relay 51CR and the source 1 air supply valve relay 88AR for 3 seconds, for example. The air compressor 51 is operated only for 3 seconds, and the source 1 air supply valve 88A is opened. As a result, the air pressure is momentarily applied to the source container 54 in the closed container 53A to make the lid member 57
Since the source container 54 is pushed out toward the opening side, the lid member 57
Also, the source container 54 can be easily taken out. Further, during this period, the source 1 LED 101 is made to blink in red to display (notify) the user that the pressure is being increased for replacement (during replacement). The user pulls out the pushed lid member 57 and the source container 54 from the container body 56 of the closed container 53A to open the opening.

After that, the control device C turns on the source 1 exhaust valve relay 92AR to open the source 1 exhaust valve 92A, discharges the air in the closed container 53A, and at the same time, opens the closed container 53A.
A new source container 54 is connected to the closed container 5 by communicating the inside and outside of A.
Make it easy to insert into 3A. In addition, the source 1LED101
Blinking in green to inform (notify) the user that the source 1 exhaust valve 92A is open during replacement. The control device C turns off the source 1 exhaust valve relay 92AR when the cover member 57 is closed (source 1 cover switch 66A is ON) or when 15 minutes have passed after the source 1 exhaust valve 92A was opened, and the source 1 was opened. Exhaust valve 92A
Close.

After that, the source extraction port member 5 is used as described above.
9 is inserted into a new source container 54 and attached to the lid member 57 by screwing to attach the source container 54 to the container body 5.
6, and the opening is closed by the lid member 57.
Then, the stopper 58 is pulled forward, rotated, and then lowered to engage the lower end with the lower holding tool 61 (the source 1 lid switch 66A is turned on) to complete the replacement. After that, if the source 1 switch 96 is pressed, the control device C prepares for extraction through pressurization as described above.

(7) Operation Abnormality Display Here, at the time of pressurization during the normal operation and the source exchange operation as described above, the air pressure in the closed container 53A becomes abnormally high based on the output of the source 1 pressure sensor 93A. In the case, or if it does not rise to the set value, it is judged that an abnormality has occurred in each valve of the source pressure feeding device 2, the air compressor 51, etc., the source 1 LED 101 is lit in red and the inspection LED 104 is lit, and the user The alarm is displayed to indicate the occurrence of an abnormality and prompt a quick inspection. Further, at the same time, the source 1 exhaust valve relay 92AR is turned on and the source 1
The exhaust valve 92A is opened to bring the air pressure in the closed container 53A to atmospheric pressure.

In addition, during normal operation, when the source 1 take-out switch 46A is OFF (that is, the state in which no frozen dessert is extracted), the air pressure in the closed container 53A is based on the output of the source 1 pressure sensor 93A. For example, when the set value (0.2 Mpa) is lowered to the lower limit value of 0.18 Mpa, the connection between the lid member 57 and the source extraction port member 59 of the source pressure feeding device 2, the hose 16A and the source extraction port. Connection portion of the member 59 with the straight pipe portion 81, the source valve 3
It is conceivable that the source leaked from the seal portion of 6 and the hose 16A itself, and the volume of the source container 54 was reduced.

The controller C uses the source 1 take-out switch 4
If a pressure drop occurs when 6A is off, it is determined that the source is leaking from somewhere and the source 1 LED 101 is lit in red and inspection L
The ED 104 is turned on to alert the user of the occurrence of an abnormality and prompt a quick inspection. At the same time, source 1
Exhaust valve relay 92AR is turned on and source 1 exhaust valve 92A
Is opened to bring the air pressure in the closed container 53A to atmospheric pressure.

Incidentally, the control device C uses the pressure sensors 93B and 9B.
