The operation of the above arrangement will be described below.

First, the beater 23 is put into the main body 9, and the concave portion 26 at the lower end of the beater is fitted into the upper end of the shaft 20 and assembled. Next, the frozen dessert material and the dry ice are measured in advance and put into the main body 9. If the lump of dry ice is large, it hits the beater 30 and does not enter the main body 9, so that it is crushed as finely as possible.

Then, the lid 10 is placed on the opening of the main body 9. At this time, the hook 10 is inserted into the inverted U-shaped locking member 18 of the main body 9 to cover the cover 10 so that the concave portion 27 of the lid 10 is fitted to the support shaft 28 at the upper end of the beater 23.

When the operation switch 7 is pressed after the container 3 is mounted on the gantry 2, the rotation of the output end 5 of the drive motor 4 is transmitted to the shaft 20, and the beater 23 rotates. At this time, the frozen dessert material and the dry ice put into the main body 9 are stirred and mixed by the stirring blade 25 and the connecting member 24, and the dry ice is crushed.

In the container 3, the dry ice sublimates vigorously to generate carbon dioxide gas, and the pressure in the container rises, dissolves in the frozen dessert material by stirring, and the frozen dessert material is cooled by the low-temperature dry ice near -80 ° C. It gradually changes to a semi-frozen state, and finally carbonated frozen dessert is completed.

If the amount of carbon dioxide gas generated from dry ice becomes excessive, the pressure in the main body 9 increases, and the hook 16, the engaging member 17, the locking member 18, and the hook 19 are deformed to break the seal, or Although the lid 10 may be deformed, when the pressure in the main body 9 exceeds a predetermined pressure, the safety valve 33 operates to release the internal pressure to the outside. The set pressure of the safety valve 33 is 800 kPa.

When the inside of the container 3 is viewed from the transparent lid 10 and it is confirmed that the dry ice has completely sublimated and the solid mass has disappeared, the operation switch 7 is turned off, and the rotation of the beater 23 is stopped. . Then, the container 3 is removed from the gantry 2 with the lid 10 attached, the container 3 is placed sideways, and the pouring cock 31 is opened to extract the carbonated frozen dessert.
At this time, the injection cock 31 is opened little by little, and the adjustment is performed so that carbon dioxide gas is not suddenly blown out.

When the amount of carbonated confectionery decreases and the pressure of carbon dioxide in the container 3 decreases, and it becomes difficult to remove the carbonated confectionery from the pouring cock 31, the hook 16 is opened, the lid 10 is opened, and the beater 23 is pulled out. By tilting 9, the carbonated frozen dessert can be poured up to the last drop, so that it is not wasted.

Next, the operation when the frozen dessert material, ice and dry ice are charged into the main body 9 will be described.

The beater 23 is installed in the main body 9 in advance, the frozen dessert raw material, ice and dry ice are put through the opening of the main body 9, sealed with the lid 10 and set on the gantry 2, and the operation switch 7 is pressed. The difference from the above is that ice is added to the container 3. With the addition of ice, diluted carbonated frozen desserts can be produced.

Next, a method for making a carbonated beverage or a carbonated frozen dessert in a case where dry ice is not available and carbon dioxide is available will be described.

The beater 23 is incorporated in the main body 9, the frozen dessert raw material and ice are put in, and the lid 10 is sealed. The ice is used for cooling and diluting, and is crushed as finely as possible so that the frozen dessert ingredients can be cooled quickly. A carbon dioxide gas cylinder (not shown) is connected to an inlet 32 with a check valve by a hose (not shown), and carbon dioxide gas is injected into the container 3. The pressure of the carbon dioxide gas is about 200 to 300 kPa. In this state, the gantry 2
, And press the operation switch 7 to turn the beater 23. The beater mixes the carbon dioxide gas and flake ice into the frozen dessert raw material in the main body 9 so that the dessert becomes carbonated frozen dessert. By adjusting the amount of ice to be charged, it is possible to make a cold carbonated beverage without reaching a frozen dessert.

Next, a method for preparing a carbonated beverage or a carbonated frozen dessert when there is no dry ice and no carbon dioxide gas is available will be described.

The beater 23 is incorporated in the main body 9 and the frozen dessert raw material, ice and a foaming agent are charged. And cover the lid 10,
The operation switch 7 is pressed, and the beater 23 starts stirring. At this time, the foaming agent and the frozen dessert material undergo a chemical reaction to generate carbon dioxide gas, and at the same time, a part thereof is dissolved in the frozen dessert material and carbonated. On the other hand, by the stirring of the beater 23, the ice and the carbonated frozen dessert raw material are mixed to form carbonated frozen dessert. A commercially available baking soda may be used as the blowing agent. If the amount of ice is reduced, carbonated beverages can be extracted.

Even if there is no carbonic material such as dry ice, carbon dioxide or a foaming agent, non-carbonic frozen desserts can be produced by using non-carbonic materials such as milk and syrup.

For example, when making frozen dessert using milk, after incorporating the beater 23 into the main body 9, milk, sugar and ice are charged, the lid 10 is sealed, and compressed air is injected from the inlet 32 with a check valve. Is added at about 100 to 300 kPa, a fluffy milk shake can be made. If syrup and ice are put in the main body 9 instead of milk, and compressed air is pressurized from the inlet 32 with a check valve, a soft drink including foam can be produced. The compressed air is obtained from a commercial electric air pump.

Further, since the opening of the main body 9 is wide, it is easy to add an additive such as pulp into the main body 9 in advance. Can also be made.

Furthermore, by adding an appropriate amount of alcoholic beverage to the main body 9, it is possible to enjoy frozen desserts containing alcohol for adults.

As another form of the present invention, a screw can be used when the main body 9 and the lid 10 are detachably connected. As shown in FIGS. 3 and 4, a male screw 36 is set on the upper end of the main body 9, and a female screw 37 is formed on the inner surface of the lower end of the lid 10. Insert the flat packing 38 into the inside of the lid 10
Is screwed, the flange 12 and the flat packing 38 come into close contact with each other, and it is needless to say that the same effect can be obtained even if the hermetic sealing of the container 3 can be maintained. The same effect can be obtained by inserting a cold storage material between the inner box 11 and the outer box 13 instead of the heat insulating material 14 of the main body 9 and cooling and using the cold storage material.

According to the first aspect of the present invention, if the beater is incorporated into the main body, and then the frozen dessert raw material and the dry ice are put into the main body in advance and the lid is closed, the carbon dioxide gas generated from the dry ice is generated. Under its own pressure, it melts into the liquid frozen dessert material and carbonates it, and the cooling action of dry ice near -80 ° C causes the liquid to be in a semi-frozen state, making it easy to produce a carbonated frozen dessert with an increased cooling sensation.

According to the second aspect of the present invention, after incorporating the beater into the main body, if the frozen dessert raw material, ice and dry ice are put into the main body in advance and the lid is closed, carbon dioxide gas generated from the dry ice will be generated. It melts into the liquid frozen dessert ingredients under its own pressure and carbonates, while being diluted with ice,
Due to the cooling effect of dry ice near −80 ° C., even a concentrated undiluted solution is used as a raw material for frozen desserts, a liquid that has been appropriately diluted is in a semi-frozen state, and a carbonated frozen dessert with an increased cooling sensation can be easily produced.

According to the third aspect of the present invention, since the spout cock is attached to the container, when the production of the frozen dessert is completed, if the container is removed from the gantry with the lid attached, the inside of the container is removed. Carbonated frozen dessert can be easily extracted using pressure.

According to the fourth aspect of the present invention, since the container is provided with an inlet with a check valve, even if there is no dry ice, the frozen dessert material and ice are put in the container in advance and the lid is closed. After closing, the carbon dioxide gas can be injected from the external carbon dioxide gas cylinder into the inlet with the check valve, and the carbonated beverage can be easily made in the container.

According to the fifth aspect of the present invention, since the container is provided with a safety valve, when dry ice and frozen dessert ingredients are charged into the container, sublimation of the dry ice generates violent carbon dioxide gas. Even if the pressure rises abnormally, it is possible to escape to the outside by this safety valve, and it is possible to prevent the deformation of the container and the lid from being detached from the main body, and the carbonated beverage inside from being scattered.
