Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an apparatus for producing a soft iced beverage at a relatively low temperature by mixing shaved ice with a liquid substance such as syrup, honey, or fruit juice.

Conventional technology Conventionally, as a semi-frozen iced beverage, there is, for example, semi-frozen sherbet made from fruit juice as the main ingredient.
This is manufactured by putting fruit juice, milk, etc. into a refrigerator and cooling and stirring. As another example, an apparatus is known that produces syrup and water by adding carbon dioxide gas and freezing the syrup and water while stirring in a refrigerator, as well as producing foam.

However, in both of these methods, a liquid beverage is agitated and cooled in a refrigerator to partially freeze it, so even if it is foamy and soft, there will be ice particles present when you eat it. While you can feel the coldness in your mouth,
The texture of these frozen particles often caused discomfort.

Problems to be Solved by the Invention The inventor of the invention of this application previously disclosed the software disclosed in Japanese Patent Application Laid-open No. 62-296843 as a solution to the problems of the conventional iced beverage manufacturing apparatus as described above. We proposed an ice cream manufacturing device.

The outline of this device is as follows: A cutting case with a slit facing the cutting blade and a shaved ice input chute; It has a rotary vane plate and a first drive motor that rotates the rotary vane plate, and includes an ice cutting mechanism installed on the machine base, and an ice cutting mechanism installed on the machine base below the ice scraping mechanism and below the shaved ice inputting chute. A rotary blade is provided in a container located in the container and mixes a liquid substance such as syrup in the container with the shaved ice put into the container, and also crushes the shaved ice into fine particles. a mixing mechanism having a second drive motor to
We succeeded in solving the problems mentioned above.

However, in this manufacturing equipment, both motors start almost simultaneously. As a result, a new problem arises in that the shaved ice remains in the upper part of the container in a lid-like manner, resulting in insufficient pulverization of the shaved ice within the container and insufficient mixing with the liquid material.

Therefore, an object of the present invention is to solve the problems of the previously proposed devices as described above, and to provide a soft ice drink in which shaved ice can be further crushed even in the container and mixed with a liquid substance smoothly. Our goal is to provide manufacturing equipment.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides a control circuit for controlling the operation of the first drive motor and the second drive motor in the previously proposed device as described above. and the control circuit is configured such that the second drive motor starts after the first drive motor starts, and the second drive motor stops after the first drive motor stops. be.

Function In the soft ice beverage manufacturing apparatus as described above, the first drive motor first operates to make shaved ice, which falls into the melter through the charging chute and sinks into the liquid. After the ice begins to cool, the second drive motor operates and the rotating blades of the mixing mechanism crush the shaved ice and mix it with the liquid in the container. Therefore, outside air is sucked into the bottom of the container, and when a predetermined amount of shaved ice has been added, the first drive motor stops, but the second drive motor continues to operate, and the second drive motor continues to operate. Thorough pulverization and mixing with the liquid material will be carried out.

Next, the operation of the above embodiment will be explained with reference to the process diagram shown in FIG.

First, the lid 37 is removed, a large amount of cube-shaped ice A, for example, is put into the storage chamber 35, and the lid 37 is closed.

Next, the container 57 is removed from the substrate 2 together with the container stand 42, and an appropriate amount of liquid substance B such as syrup is poured into the container 57. The container 57 is then moved so that the upper coupling ring 47 engages the lower coupling ring 48.
is mounted and supported on the substrate 2 together with the container stand 42. After completing the preparations in this way, when the user wants to get a drink for one person, the first switch 71 is turned on. As a result, the count "1" is set in the counter 74 by the signal from the first input section 37,
The signal is input to the control unit 75, and the H level signal is input from the control unit 75 to the first timer 76 and the third timer 78. In this way, the first timer 7
The signal input to 6 is the time set in the same timer 76.
During T1, an H level signal is output, and the first motor 14 is energized via the output section 86 and the relay 92,
During this time T1, the motor 14 is operated to cut the ice block A with the cutting blade 19, and the shaved ice C thus formed is thrown into the liquid B in the container 57 as shown by the arrow.

In this way, after the time T1 has elapsed, the first timer 76
outputs an L level signal, which causes the first motor 14 to stop, and the second timer 77 outputs an H level signal, which becomes an L level signal after the time T2 set in the timer 77. This is input to the counter 74 and counted by one, and the counter 74 outputs an L level signal.
This signal and the L level signal transmitted via the delay circuit 83 are input to the control section 75 almost simultaneously.

On the other hand, when the signal input from the control section 75 to the third timer 78 is switched to the L level after the time T3 set in the third timer 78 has elapsed, the signal from the flip-flop 88 is switched from the L level to the H level, and the output section 86 and the relay 93 to operate the second motor 50, and the high-speed rotating blade 5
3 and 54, the shaved ice C and the liquid substance B are made to flow in a spiral shape inside the container 57 as a spiral vertical swirling flow that draws the center part down and generates air bubbles while rising on the outside. As a result, the shaved ice C is made even finer and mixed with the liquid B.

When the second motor 50 is operating in this manner, after the time T2 set in the second timer 77 has elapsed,
As described above, the L from the counter 74 and the timer 77
The level signal is input to the control unit 75, the L level signal is conducted to the flip-flop 88, the signal is switched from the H level to the L level, and in this way the second motor 50 rotates for a time T4. time
Stops after T2.

In this way, the shaved ice C is atomized and mixed into the liquid substance B to produce a soft ice drink containing air bubbles.
The coupling rings 47, 48 are disengaged and removed from the base plate 2, and the beverage in the container 57 is transferred to another cup and served.

In this case, the ice block A is first cut by the cutting blade 19, and the shaved ice C thus made is placed in the container 57.
Since the rotary blades 53 and 54 are not yet rotated at this time, the liquid B does not scatter outside the container 57, and the shaved ice C is Since it is thrown into the container 57 without being affected by the rotary blades 53 and 54, it does not gradually sink to the bottom of the container and stay above it as if it were covered. Therefore, it is sufficiently crushed by the rotary blades 53 and 54 that start rotating after that, and is mixed well with the liquid material B.

The finished beverage is soft and has an extremely pleasant texture without the presence of ice particles, and has a quality intermediate between that of conventional cream and sherbet. Furthermore, since the fine particles of shaved ice in the beverage are surrounded by bubbles, they do not melt easily and are kept sufficiently cold during the time it is poured into a cup and eaten.

Next, when producing iced drinks for two people, the second switch 72 is turned on.

This is inputted to the counter 74 by a signal from the second input section 73' to set the count "2", and the signal is inputted to the control section 75 and stored. 78.

Then, the same operation as when for one person is performed,
The first motor 14 stops immediately after the elapse of time T1, but the second timer 77 stops when the set time T2 elapses.
A high level signal is output, which is input to the counter 74 and counted by one, but due to the remaining count "1", the H level signal output from the counter 74 is input to the control section 75 and outputs an H level signal. The output is input to the first timer 76 and the third timer 78, and the first motor 14 is activated again for the second time.
After operating for T1, the motor 14 is stopped.

At the beginning of the second time T1, the signal input from the control section 75 to the flip-flop 88 is still at H level, and the second motor 50
continues to operate.

Then, after the second time T2 has elapsed, that is, after the second time T1 plus T2 (time T5) has elapsed, the second timer 77 is activated, and the signals input from the counter 74 and the timer 77 to the control unit 75 are 1
As in the case for human use, the signal goes to L level, clears the flip-flop 88, and stops the second motor 50.

As a result, the ice cutting process is started first, and then the mixing process is started after the elapse of the time T3, and the ice cutting process is interrupted for the time T2 after the elapse of the time T1, but the mixing process continues. Thereafter, the ice cutting process continues for a time T1, and then the same process ends, and after a time T2 has elapsed, the mixing process also ends, and the total cycle of the mixing process becomes time T6.

If this is for 3 people, just add 1 person in the same way as the 2 people in Figure 3, and the same is true even if there are more people. Normally, if you supply shaved ice continuously at one time for a large number of people, it is often not possible to grind and mix the ice sufficiently, so first make the drink for one person in several batches. , the motor 50 continues to operate to continue mixing and crushing, and then the motor 14 restarts to shave ice for the next person and then stops, which is repeated to ensure sufficient crushing and mixing. This is to do this.

Note that this embodiment is as described above, and a large amount of ice cubes is placed in the ice cube storage chamber 35 in advance.
A large amount of soft iced beverages will be produced at one time, and the ice cubes A that have been put into the storage chamber 35 are linked to the movement of the ice cubes in the cutting case 7, and automatically moved by the slope of the funnel-shaped wall 38. It moves to the center and is guided into the cutting case 7 via the hopper 28. When such ice blocks A are reduced by cutting, the situation is visible from the outside because the peripheral wall 36 is transparent, and the storage chamber 35 is replenished with ice blocks as necessary.

In addition, during mixing, the shaved ice and the liquid form a spiral vertical swirl flow and descend from the center, as described above.
Since it rises on the outside, the air above the mixture in the center is drawn downward into the container 57. However, the drawn air forms a space near the rotary blades 53 and 54, and the rotary blade 5
The grinding and mixing functions of No. 3, 54 may be inhibited. However, since this rotating shaft 45 has a rectangular cross section as described above and extends upward,
The air that tends to stay rises around the rotating shaft 45 and is dissipated to the outside, thereby preventing the above-mentioned phenomenon from occurring. Furthermore, since the solid state relays 92 and 93 in the control circuit generate a lot of heat, it will have an adverse effect on the entire device if a heat dissipation member is not installed. Since it is made of aluminum, it serves as a heat radiating member and there is no need to use a special heat radiating member.

Effects of the Invention The present invention provides a soft iced beverage manufacturing apparatus as described above, in which the first drive motor of the ice cutting mechanism and the second drive motor of the mixing mechanism are started by a control circuit. and stop,
Since the speed is faster than that of the second drive motor, the shaved ice fed from the ice shaving mechanism to the mixing mechanism accumulates above the container of the mixing mechanism, creating a lid-like state, which causes the rotary blades of the second drive motor to The effect is that there is no need to rotate the shaved ice, which results in insufficient pulverization of the shaved ice and insufficient mixing of the shaved ice with the liquid, and that an extremely soft drink with no ice particles and a cold and pleasant texture can be efficiently obtained. be.
