Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides soft cream, hard cream,
Alternatively, the present invention relates to a mixed frozen dessert manufacturing method for producing a mixed frozen dessert by adding fruit pulp or dry toppings or other additives to a frozen dessert such as whipped cream, and stirring and mixing the additives.

[Conventional technology]

BACKGROUND ART Conventionally, there has been known a method of producing mixed frozen desserts by adding additives such as fruit pulp to frozen desserts such as soft serve ice cream, and stirring and mixing the mixture. In such a method for producing mixed frozen desserts, for example, a mixer device is used.

As shown in FIG. 5, this mixer device simply has an agitator 4 attached to a motor 2 provided at the top of the device body 1 via a long motor shaft 3. The mixed frozen dessert produced by the above-mentioned mixer device is simply a mixture of the frozen dessert and the additive in the container, and the mixing adjustment of the frozen dessert and the additive and the extraction from the mixing container are performed. The problem was that everything had to be done manually.

Therefore, in recent years, a device has been proposed in which the mixing container is raised and the frozen dessert and additives in the mixing container are mixed by a mixing auger located above the mixing container (Japanese Patent Application Laid-open No. 61-187753 and Japanese Patent Application Laid-open No. 60-259146).

However, in the above-mentioned conventional apparatus, when mixing the frozen dessert and the additive with the mixing auger, the action of mixing the frozen dessert is simultaneously accompanied by the action of extracting the frozen dessert by pushing the frozen dessert out of the container. For this reason, depending on the type of frozen dessert or additive, the mixed frozen dessert may be extracted from the container without a sufficient mixing state of the frozen dessert and the additive. In addition, depending on the type of frozen dessert or additive, a moderate mixing state may be required, but even in such cases, conventional equipment performs the mixing action and extraction action at the same time, so the mixing state cannot be adjusted. Unable to make adjustments. Furthermore, when extracting mixed frozen desserts, not only is it not possible to perform the extraction operation of frozen desserts as needed separately from the above-mentioned mixing operation, but the mixing auger is constantly rotating even during the extraction operation of mixed frozen desserts. This poses a danger to users when extracting frozen desserts. Moreover, since no stirring action is involved when mixing frozen desserts, mixing cannot be done in a short time. Furthermore, since the lifting stroke of the container is long, there is a problem in that the supporting state of the container tends to become unstable.

[Purpose of the invention]

The present invention has been made in consideration of the above-mentioned conventional problems, and allows frozen desserts such as soft serve ice cream and additives such as fruit pulp to be easily stirred and mixed in a short period of time, and further, By switching between the mixing operation for mixing frozen desserts and additives and the extraction operation for mixed frozen desserts, it is possible to safely extract an appropriate amount of a properly mixed mixed frozen dessert, and the lifting stroke of the mixing container can be shortened. The object of the present invention is to provide a method for producing a mixed frozen dessert.

[Structure of the invention]

In order to achieve the above-mentioned object, the mixed frozen dessert manufacturing method according to the present invention involves putting frozen desserts such as soft cream and additives such as fruit pulp into a mixing container having an extraction port at the bottom, and then putting the mixing container into the mixed container. The frozen dessert and the additives are stirred and mixed by gradually raising the stirring blade and introducing it into the mixing container while rotating the stirring blade. The mixing container is stopped to complete the above-mentioned mixing process, and the mixing container is held stationary once at the fully raised position.Then, the piston is guided by the motor shaft to which the stirring blade is attached, so that the piston does not rotate. The piston is lowered in this state, and the piston is sent into the mixing container to push out the mixed frozen dessert in the mixing container from the extraction port.

〔Example〕

An embodiment of the present invention will be described below based on FIGS. 1 to 4.

As shown in FIG. 1, a drive motor (not shown) for the stirring device 10 is provided at the top of the frozen dessert mixing device 9. This drive motor is provided with a long motor shaft 11, and an agitator 12 is fixed to the lower end of the motor shaft 11.

As shown in FIG. 2, the motor shaft 11 is provided with a piston 13 serving as a frozen dessert extracting member, which is inserted through a through hole 13a formed approximately in the center of the motor shaft 11. , is provided slidably between the end of the motor shaft 11 on the drive motor side and the end of the stirring blade 12 side, using the motor shaft 11 as a guide.

A dispense lever 14 is provided in the vicinity of the piston 13 so as to be swingable in the direction A-B on a shaft 15, and the dispense lever 14 and the piston 13 are connected by a link 16. . The above piston 13, dispense lever 1
4, and the frozen dessert extraction means 17 by the link 16
is configured.

Below the motor shaft 11, a blend cup 18 serving as a mixing container is held by a cup holder 19. Above blend cup 1
The inner diameter of the piston 8 is set to be approximately the same as the outer diameter of the piston 13. Also, blend cup 18
has a funnel shape at its bottom, and an extraction port 18a opened in an arbitrary shape such as a star shape is formed at the bottom for extracting the mixed frozen dessert mixed in the blend cup 18. ing.

The cup holder 19 has a through hole formed approximately in the center thereof to hold the blend cup 18 concentrically with the motor shaft 11;
There are slide shafts 20, 2 near this through hole.
A guide hole is formed through which the 0 is inserted. The cup holder 19 is guided by inserting the vertically extending slide shafts 20, 20 into guide holes.

As shown in FIG. 3, one end of a link 21 is connected to the cup holder 19, and the other end of the link 21 is connected to a link whose one end is supported by the frozen dessert mixing device 9 22 are connected. Furthermore, link 2 in link 22
One end of a link 23 is connected to the first side, and one end of an L-shaped blend lever 24 is connected to the other end of the link 23.

This blend lever 24 has a bent corner 24
It is provided so as to be swingable in the CD direction using a as a fulcrum. Therefore, the cup holder 19 can move up and down in conjunction with the blend lever 24 while holding the blend cup 18 concentrically with the motor shaft 11 and on the extension line of the motor shaft 11. There is. The cup holder 19, slide shafts 20, 20, links 21 to 23, and
The blend lever 24 constitutes a container lifting means 25. The cup holder 19 is also provided with a seal cap 26 that can be pivoted by an arm 27 to seal the frozen dessert if it leaks from the extraction port 18a.

The start and stop of the rotation of the drive motor is controlled in accordance with the upper and lower limit positions of the blend cup 18 which is moved up and down by the container lifting means 25.

To produce a mixed frozen dessert, first, an appropriate amount of frozen dessert such as soft serve ice cream is put into the blend cup 18.
At this time, the frozen dessert is added to the blended cup 18.
The extraction port 18a formed at the bottom of the container is inserted so as to close the extraction port 18a to prevent the next additive to be added from leaking from the extraction port 18a.

Next, additives prepared in advance, such as topping sauce such as concentrated fruit juice, dry toppings such as peanuts, chiyocolate, kutsky, and dried grapes, and fruit pulp are added to the blended cup 18.
put it in. At this time, if the frozen dessert leaks from the extraction port 18a, apply the seal cap 26 to the extraction port 18a.

Next, slowly turn the blend lever 24 to D.
Push down in the direction. When the blend lever 24 swings in the D direction, the respective links 23, 2
2 and 21 are interlocked in sequence, and the cup holder 19 begins to rise. When the cup holder 19 rises and the blend cup 18 reaches the position (lower limit position) where the stirring blade 12 begins to be accommodated therein, the lower limit micro switch 29 detects this, and the lower limit micro switch 29 and the relay 31 The drive motor begins to rotate due to the action. When the drive motor rotates, the stirring blade 12 also rotates, and the rotation of the stirring blade 12 causes the blend cup 1 to
The frozen dessert and additives in Step 8 are stirred and mixed. At this time, the piston 13 does not rotate with the rotation of the drive motor and is in a non-rotating state.

When the blend lever 24 is further pushed down in the D direction, the blend cup 18 further rises,
The upper limit micro switch 30 operates at the position just before this rises completely (upper limit position), and the rotation of the drive motor is stopped. Therefore, stirring blade 1
The rotation of No. 2 is stopped, and the process of mixing the frozen dessert and the additive is completed.

Further, when the blend lever 24 is pushed down to the final swing position, the operating rod portion 24b of the blend lever 24 and the link 23 are in a straight line state. Therefore, even if the blend lever 24 is released, the cup holder 19 is temporarily held stationary at the fully raised position.

Next, the dispense lever 14 is pushed down in the direction B as shown in FIG. Since the downward force of the dispense lever 14 is transmitted to the piston 13 via the link 16, the piston 13
It is guided by the motor shaft 11 and slides toward the stirring blade 12 side in a non-rotating state. Therefore, the piston 13 is gradually fed into the blend cup 18 and begins to push out the mixed frozen dessert in the blend cup 18 from the extraction port 18a. Here, since the extraction port 18a is opened in any predetermined shape, the mixed frozen dessert in the extracted state can be mixed by simply placing it in a paper cup serving as a serving container or an edible container such as a corn cup. The frozen dessert is molded into the desired shape. Thereby, mixed frozen desserts having various shapes, colors, tastes, etc. can be easily and quickly produced in the required amount.

Next, push the blend lever 24 back in the C direction to return it to its original position, and press the blend cup 1.
8 to its original position. At this time, the blend cup 18 returns and passes through the upper limit position and the lower limit position, but since the power supply to the drive motor is stopped by the action of the relay 31, etc., the stirring blade 12 does not rotate.

Next, the dispense lever 14 is pushed back in the A direction to raise the piston 13 toward the drive motor. Then, the stirring blade 12 and the piston 1 are used in the cleaning nozzle 32 for the mixed frozen dessert to be manufactured next.
3, and the blend cup 18 is cleaned.

In this embodiment, manual types are shown as the frozen dessert extracting means 17 and container lifting/lowering means 25, but it goes without saying that electric types may also be used.

〔Effect of the invention〕

As described above, in the mixed frozen dessert manufacturing method according to the present invention, frozen desserts such as soft cream and additives such as fruit pulp are put into a mixing container having an extraction port at the bottom, and then the mixing container is gradually raised. By rotating the stirring blade while introducing the stirring blade into the mixing container using a lever, the frozen dessert and additives are stirred and mixed, and the stirring blade is stopped at a position just before the mixing container reaches the top. After the mixing process is completed, the mixing container is held stationary at the fully raised position, and then guided by the motor shaft to which the stirring blade is attached, the piston is lowered in a non-rotating state. This piston is sent into the mixing container to push out the mixed frozen dessert in the mixing container from the extraction port.

In this way, the mixing process ends at the position just before the mixing container reaches its full height, and after the mixing container is held stationary once at the fully raised position, the process moves on to the extraction process of the mixed frozen dessert at any time. Therefore, depending on the types of frozen desserts and additives, it is easy to obtain an appropriate mixed state of frozen desserts and additives. Further, when extracting the mixed frozen dessert, an operation for extracting an appropriate amount of the mixed frozen dessert can be performed as necessary, separately from the above-mentioned mixing operation. Furthermore, during the process of extracting mixed frozen desserts, the stirring blade is in a stopped state, and the piston for pushing out mixed frozen desserts is also in a non-rotating state, which may pose a danger to users when extracting mixed frozen desserts. do not. Further, since the frozen dessert in the mixing container is mixed while being stirred by the stirring blade, a sufficient mixed state can be obtained in a short time.
Furthermore, since the piston for extracting the mixed frozen dessert and the mixing container are moved in the direction toward which they approach each other, the lifting stroke of the mixing container can be shortened, and the supporting stability of the mixing container can be easily maintained.

In addition, according to the method of the present invention, a link mechanism with a simple structure is adopted, and the movement of raising the mixing container and the operation of once holding the mixing container in a stationary state at the fully raised position are performed by the link mechanism. This can be achieved reliably and easily, and has the advantage of being able to reduce manufacturing costs.
