The sauce filled in the sauce container 54 is substantially the same as a soft cream mix, such as strawberry jam, which is substantially free of a soft cream mix and which has been cooled to a semi-cured state. A fluid material exhibiting a certain degree of fluidity is used. The soft serve mix used is a soft serve mix powder (40% to 45% sucrose, about 50% milk solids) to which about twice the amount of water has been added.

With the above configuration, when the extruding device 52 presses the bottom wall 54A of the source container 54, the convex portions 59A, 59A of the piston 59
The other part is pressed to deform the part other than the hard part 54B of the bottom wall 54A inward.

As a result, the amount of the source finally remaining in the source container 54 due to the presence of the hard portion 54B can be reduced, so that the waste of the source can be reduced and the economy is improved. Can be done.

Here, reference numeral 63 denotes an inner lid for opening and closing the front opening of the cylinder 53, and reference numeral 64 denotes a handle provided at one end of the inner lid 63. 8 and 9 are attached to the other end of the inner lid 63.

With the inner lid 63 closed with the front surface of the cylinder 53 closed, one end of the inner lid 63 is lowered to the lower side (moves to the non-pivot side) and attached to the base 57 as shown in FIG. It is engaged with the rear side of the holding plate 71 as a stopper.

When replacing the source container 54, the inner lid 63 is lifted (moved to the pivot side) along the elongated hole 66 with the handle 64, and disengaged from the holding plate 71. The front end of the cylinder 53 is opened by rotating one end upward. Then, when pushed in a horizontal state, the other end (rear end) of the inner lid 63 is engaged with the substantially inverted L-shaped engagement plate 72 attached to the upper portion of the front plate 67, so that the open state is maintained. (FIG. 9).

Next, FIG. 10 shows a control circuit diagram of the source pumping device 2. The source pumping device 2 is controlled by a general-purpose microcomputer 80 as shown in FIG. The microcomputer 80 also controls production and extraction of frozen dessert by the cooling device R and the beater motor 9, but the description is omitted here. On the input side of the microcomputer 80, a current sensor 81 as current detecting means for detecting a current supplied to the source extraction motor 51, a switch circuit 82, the origin switch 79, the preparation switch 73, and a sold-out switch 78 are provided. It is connected.
A motor for turning on / off the source extraction motor 51 is provided on the output side of the microcomputer 80.
A relay 83, a motor low speed relay 84 for operating the motor 51 at a low speed, a motor reverse rotation relay 85 for rotating the motor 51 in reverse, a motor protection relay 86,
An automatic LED 87 composed of a D lamp, a retreat LED 88 and a cartridge LED 89 (the cartridge means the source container 54) are connected.

The operation of the source pumping apparatus 2 having the above configuration will be described with reference to the timing chart of FIG. At this time, the piston 59 is most retracted, and the pusher 77 has turned on the origin switch 79. Then, the inner cover 63 is opened as described above, and the source container 54 in which, for example, strawberry jam is sealed is loaded into the source pressure feeding device 2,
The hose 16 is connected to the extraction port 47 with the bottom wall 54A facing the piston 59. If the automatic switch of the switch circuit 82 is ON, the microcomputer 8
0 turns on the motor ON relay 83 and the motor low speed relay 84 with the source container 54 thus set.

As a result, the source extraction motor 51 rotates forward at a low speed, for example, five times a minute, and the source container 54
Is pressed slightly from behind to apply a preload.
At this time, the convex portions 59A, 59A of the piston 59 contact the outside of the hard portion 54B of the source container 54, gradually advance to apply pressure from behind, and the microcomputer 80 blinks the automatic LED 87.

Since the load on the source extraction motor 51 increases as the piston 59 presses the source container 54, the current (motor current) increases. The microcomputer 80 monitors the energizing current of the source extracting motor 51 by the current sensor 81. When the energizing current of the source extracting motor 51 increases to an initial setting current (for example, 0.31 A) to which a specified preload is applied, the motor is turned on.
The relay 83 is turned off, and the source extraction motor 51 is stopped. The air existing in the hose 16 and the like is pushed out from the gap between the source valve 36 and the recess 26 by the preload operation, and the source is pushed out to the source valve 36. And
The automatic LED 87 is always turned on to end the preload operation, and the system enters a sales standby state.

When the lever 10 is lowered in the sales standby state, the connecting arm 38 of the source valve 36 is raised as the plunger 20 is raised, and the introduction groove 2 is moved as described above.
4 is opened, the source container 5 is connected via the hose 16.
4 and the discharge nozzle 5 are communicated.

Further, the switch 44 is turned on via the arm 42 by raising the source valve 36, so that the beater motor 9 is turned on, and the beater 7 is rotated.
When the switch 44 is turned on, the pulp extraction switch of the switch circuit 82 is also turned on. When the pulp extraction switch is turned on, the microcomputer 80 sets the motor ON relay 83
Then, the motor low speed relay 84 is turned on, and the source extraction motor 51 is rotated forward at low speed.

As a result, the source container 54 is
Since the bottom wall 54B is pressed by the piston 59,
As the load increases, the current flowing through the source extraction motor 51 also increases. Then, as described above, the current (motor current) of the motor 51 during source extraction by the current sensor 81 is performed.
Is monitored, and when it reaches a predetermined extraction set current (upper limit: 0.4 A, for example), the microcomputer 8
0 indicates that the motor ON relay 83 and the low speed relay 84
The power supply to the source extraction motor 51 is stopped.

After stopping for 0.5 second, for example, the microcomputer 80 turns on the motor ON relay 83 and the low speed relay 84 again to energize the source extracting motor 51, and the lever 10 is raised, and the switch 4
The cycle of energizing (operating) / stopping the source extracting motor 51 until 4 is turned off and the pulp extracting switch is turned off is repeated.

With this control, the piston 59 presses the bottom wall 54A of the source container 54, so that the source in the source container 54 is pushed out from the extraction port 47 and enters the extraction nozzle 5 through the hose 16.

The source entering the ejection nozzle 5 is the introduction groove 2
From 4, it reaches the arc-shaped groove 23, where it is split right and left, and then discharged from the outlets 32, 32. As a result, the sauce consisting of strawberry jam is continuously added to the periphery along the flow of the soft cream extracted from the extraction passage 15 through the through-hole 31 of the star-shaped adapter 19, so that the extraction is performed. The unique sauce pattern is formed on the surface of the soft ice cream, which increases the willingness to purchase and allows customers to enjoy the unique flavor of strawberry jam from the beginning to the end of eating.

The extraction set current (upper limit value) of the source extraction motor 51 can be adjusted by a setting switch of the switch circuit 82. Thus, the pressure applied to the source container 54 can be adjusted to appropriately adjust the extraction flow rate of the source per unit time, that is, the amount of the source added to the surface of the soft ice cream.

Also, as described above, a predetermined pressing force is applied to the source container 54 by repeating the energizing (operating) / stopping cycle of the source extracting motor 51 during the pressing and extracting of the source. As compared with the case where the source extraction motor 51 is operated, stable source extraction can be performed, power consumption can be reduced, and the load on the motor 51 can be reduced. Therefore, the life of the motor 51 can be extended.

In this case, since the sauce is not mixed into the mix tank 6, a material which is deteriorated by heat sterilization can be used, and the gorgeous appearance and unique flavor of the soft ice cream can be enjoyed. Become like

When the extraction is completed, the lever 10 is pushed up and the plunger 20 is pulled down. Since the source valve 36 is also lowered as the plunger 20 is lowered, the introduction groove 24 in the take-out nozzle 5 is closed, thereby stopping the addition of the source. Also, source valve 3
6 closes the introduction groove 24, so that leakage of the source from the outlet 32 is also prevented.

When the source valve 36 is lowered, the switch 44 is also turned off via the arm 42, so that the pulp extraction switch is also turned off, and the microcomputer 80 turns off the motor ON relay 83 and the low speed relay 84 to turn off the source extraction motor. 51 is stopped. When one frozen dessert selling operation (extraction of soft serve ice cream and sauce) is completed, the microcomputer 80 counts up the number of sales of the internal memory (counter). As a result, the number of frozen desserts can be managed.

The source container 54 is gradually crushed by such extraction of the source, the volume thereof is reduced, and the shaft 61 and the piston 59 are advanced. Then, when the amount of the source in the source container 54 becomes small, the pusher 77 presses the preparation switch 73 to turn it on. When the preparation switch 73 is turned on, the microcomputer 80 blinks the cartridge LED 89 to notify the user that the amount of the source in the source container 54 is small.

Further, as the source is extracted, the volume of the source container 54 is further reduced. When the piston 59 reaches the extraction port 47 (see FIG. 7), the pusher 75 is sold out. Since the switch 78 is pressed to turn on, the microcomputer 80 turns on the cartridge LED 89 by turning on the sold-out switch 78, detects that the source container 54 is empty, and blinks the automatic LED 87.

When the sold-out switch 78 is turned on, the source container 54 is crushed to the state shown in FIG. At this time, the protrusions 59A, 59A of the piston 59 press the bottom wall 54A of the outer portions of the hard portions 54B, 54B of the source container 54, and the outer portions of the hard portions 54B of the bottom wall 54A project from the hard portions 54B, 54B. It is deformed inward as much as.

Here, when the bottom wall 54A of the source container 54 is pressed by a flat piston, the hard portion 54B is not crushed, so that at least the projection of the hard portion 54B is provided between the bottom wall 54A and the inner lid 63. An interval is formed, and the source corresponding to the volume remains, but the protrusions 59A, 59A
Pushes the bottom wall 54 of the portion (outside portion) other than the hard portion 54B toward the inner lid 63, so that the residual amount of the source is significantly reduced.

After the sold-out switch 78 is turned on,
For example, after 0.5 seconds, the microcomputer 8
0 turns on the motor reverse rotation relay 85 this time,
After 0.5 seconds, the motor ON relay 83 is turned on. As a result, the motor 51 is reversed and the piston 5
9 goes back to the initial position. When the pusher 77 pushes the origin switch 79 to turn it on, the microcomputer 80 detects the initial position and the motor ON relay 83
And the motor reverse rotation relay 85 is turned off. At this time, since the motor low speed relay 84 is OFF, the speed of the source extraction motor 51 at the time of reverse rotation is about six times as high as that at the time of normal rotation at the time of normal rotation.

Thereafter, when the source container 54 is replaced,
The preload operation is performed again, and a standby state is set. The sauce is not limited to the strawberry jam of the embodiment, but blueberry jam, apricot jam, chocolate and the like are also effective.

[0062]

As described in detail above, according to the present invention, the first
Sauce can be added to the surface of the frozen dessert extracted from the take-out passage, and a unique sauce pattern is formed on the surface of the extracted frozen dessert to increase the willingness to purchase As a result, customers can enjoy the unique flavor of the sauce along the flow of frozen dessert.

In particular, since the second extraction passage is formed in a different system from the first extraction passage, when providing a dessert without the addition of a sauce, the dessert must be removed from the second extraction passage. Thus, it is possible to provide a frozen dessert having no sauce attached.
