Hereinafter, the use procedure of the pressure type agitator according to the present invention will be described.
In the present invention, since a vacuum pump is connected, it is possible to perform agitation in both pressurized and depressurized states.
1. First, raw materials to be stirred are put into a stirring tank.
2. The stirring tank is housed in a pressure tank and fixed, and a stirring blade having a desired shape is attached to the rotating shaft.

3. The lid of the pressurizing tank is closed and fixed with a fixing screw, the internal LED lamp is turned on, and the inside of the stirring tank is made visible through the observation window.
4). When decompression processing is performed, the vacuum pump is operated and the suction port valve in front of the suction port is opened. Since food ingredients are contained here, it does not drop below the tricritical point of water.

5. By observing the compound meter, when the predetermined pressure is reached, the operation of the vacuum pump is stopped and the suction valve is closed.
6). In this machine, it can stir here as needed.
7). If only stirring under reduced pressure is required, the exhaust port is opened after the stirring is completed, and the following 13. Migrate to

(When stirring under pressure, skip 7 and go to 8.)
8-a. When pressurizing in the atmosphere, turn on the compressor and open the inlet.
8-b. When pressurizing with a specific gas other than the atmosphere, the valve of the high-pressure gas cylinder in which a specific type of gas is sealed is opened.

13. After confirming that the pressure has returned to normal pressure with a compound meter, remove the fixing screw and open the lid.
14 The raw material in the agitated tank is taken out as it is, or a desired confectionery, cake or other food is completed by baking, steaming or boiling.
As for some foods, 1. In some cases, the process may be stirred again.

The effects of the pressure stirrer according to the present invention will be summarized below.
First, since this machine is used by putting a stirring tank in a pressure tank, the following effects are exhibited.
Easy to take out the material to be stirred.
Since the stirring tank can be taken out and washed, it is clean.
Hot water or cold water can be put between the pressurizing tank and the stirring tank, and heating or cooling during stirring can be performed.
It is also possible to adjust the temperature of the stirring tank continuously by installing a piping coil comprising a pipe between the pressure tank and the stirring tank and circulating cold water, refrigerant or hot water inside the pipe.

In the present invention, as described above, since the agitation tank can be detachably accommodated in the pressure tank, a large number of agitation tanks are prepared, and the workability can be greatly improved.
In other words, this pressurized stirring work time can be short, so if various types of raw materials are added and various types are prepared, washing of the stirring tank, preparation, post-treatment, etc. Therefore, there is no waste and the workability is greatly improved.
Although this machine is compact, it is highly versatile and can be manufactured in large quantities or types by preparing a large number of stirring tanks and using them in sequence.

The conventional foaming machines, hand mixers, hand mixers, tabletop whisks, etc., have limited foaming even if they are mixed, but according to this machine, the foaming effect becomes very large. For example, it is suitable for producing fresh cream and the like.
Even if the conventional instrument does not foam even if it is mixed somewhat, according to this machine, it can be foamed.
For example, a mixture of flour and whole egg: sugar.
Compared to the conventional technology that dissolves gas such as carbon dioxide and laughing gas in a bubble and then bubbles it, it is cheaper and safer when using the atmosphere (in the case of laughing gas) It becomes a cause of global warming.) However, it is not necessary to vacuum because it is the atmosphere. For example, chocolate confectionery with foam (using carbon dioxide), fresh cream (using laughing gas).

This machine is more versatile than the conventional technique of blowing high pressure gas (atmosphere or other gas) into a liquid, and if it is foamed, it can be bubbled without greatly changing the machine.
In this machine, since the inside of the pressurizing tank can be evacuated, the following operation is possible.
Can be bubbled with any gas, not the atmosphere.
With conventional machines, it was not possible to make bubbles with only inert gas.
Foamed foods, such as fresh cream, will dramatically increase the surface that comes into contact with the air due to foaming, and the oil is likely to oxidize, but this machine is vacuumed and then filled with an inert gas. Bubbles of inert gas (nitrogen gas, argon gas, helium gas, etc.) can be made, and therefore oxidation can be prevented.

Furthermore, the conventional technique cannot make a bubble of only nitrogen gas.
Nitrogen has a larger molecule than oxygen, and if the film contains hydrogen atoms, its affinity is lower than oxygen, so the curtain is said to be difficult to escape. Can be made.
When stirring while reducing the pressure with a vacuum pump, the time for vacuum drying can be shortened.
In this machine, since a non-contact gear is used as a transmission means between the rotary drive shaft of the electric motor and the rotary shaft of the stirring blade, no mechanical joint is used and there is no fear of oil coming out.

Since the capacity is about 17 liters, there is no regulation as a pressure vessel, and no regular inspection or qualification is required.
In addition, in the pressurization tank of this machine, the test was performed by applying a pressure of 2 MPa by a water pressure test to confirm safety.
The compressor is oil-free because it uses a diaphragm type.
An LED lamp is provided inside the stirring tank so that the state inside the stirring tank can be visually observed from the outside through the observation window.

Since the lid is fixed by a single fixing screw, there is no problem even if it is simple and forgets to close or is opened without a pressure reducing operation.
If trapezoidal screws are used as the fixing screws, they are resistant to wear and can be fastened quickly.
The foam produced by this machine contains a larger amount of foam than the conventional machine, so that the apparent volume may be increased.
For example, half the material can be made as large as a conventional instrument, resulting in low calories. In addition, material costs can be saved.

Since many bubbles are included or large bubbles are included, one having a good touch can be produced.
It is possible to reduce or eliminate the amount of foaming aid (such as baking soda, yeast, and yam) added.
By adding a foaming aid to food that does not foam under normal operation, it is possible to make something different from before.

Although the embodiment has been described above, in the present invention, the form can be variously changed as follows.
The shape, size, etc. of the pressurization tank can be changed as appropriate, but in the present invention, since the compact apparatus is taken into consideration, the capacity thereof is set to about 17 liters.
In the above embodiment, the fixing screw for fixing the lid portion is provided at one location on the opposite side of the pivot support portion. However, the number of the fixing screws may be two or more.

The air spring type arm portion that assists in opening and closing the lid portion can be replaced with another one.
The shape, size, and capacity of the stirring tank can be freely designed.
Different shapes of the stirring blades can be prepared and used as necessary.
The pressure in the pressurizing tank can also be set as necessary, and stirred and foamed.

The food material to be stirred may be any food material, and raw materials such as desired foods, whipped cream, sponge cake, cheesecake, ice cream, chocolate and other confectionery can be put into a stirring tank and stirred.
According to this material, the shape of the stirring blade may be selected as appropriate.

The part connected to the vacuum pump and the position of the inlet connected from the compressor or the high-pressure gas cylinder can be appropriately set to a desired position of the lid.
At this time, it is highly desirable that the opening of the introduction port be directed to the window surface inside the pressurizing tank of the observation window so that gas can be blown onto the window surface.
Finally, the table-type pedestal that supports and fixes the pressurization tank can also be redesigned as appropriate, and without this pedestal, the pressurization tank has a bottomed cylindrical shape and the bottom surface is formed in a flat shape Therefore, it is possible to form the gantry in a form that does not particularly require.

  As described above, the present invention is configured so that the agitation tank can be housed or taken out in the pressure tank to form a two-tank type, and various confectionery and cake raw materials are agitated and bubbled under pressure or reduced pressure. It is possible to provide a pressure type agitator that can be used.
