Description

[Detailed explanation of the invention] [Industrial application field] This invention uses seaweed (Amakusa), which is the raw material for tokoroten.
It relates to a pressure cooker used for boiling.

[Conventional technology]

Generally, tokoro-ten is made by washing and exposing the raw material Amakusa, boiling it in a pot, and pouring the broth, which has been filtered from lye and lees, into a mold and solidifying it. Therefore, the quality of tokoroten also depends on how much lye and dregs can be filtered out of the broth. Conventionally, Amakusa was boiled in a pressure cooker, and the pressure (internal pressure) generated within the pot during boiling was used to send the broth to a filter. In other words, a pressure cooker was used to obtain the pressure to send the broth to the filter.

Figure 4 is a drawing showing a specific example of this,
1 represents a pressure cooker (hereinafter referred to as "pot 1").
This pot 1 has a main body 2 and a lid 4 formed into a cylindrical shape with a bottom.
It is provided in a sealable manner by a packing 13 and a locking bolt 35. More specifically,
Flange rings 15 and 16 are welded to the outer periphery of the opening of the main body 2 and the outer periphery of the lid 4 so as to face each other, and cutout grooves 36 are formed in the flange rings 15 and 16 at regular intervals.
... is provided, a lock bolt 35 is inserted therein, and the hook 1 can be sealed by tightening the lock bolt 35. The pot 1 is equipped with a strainer net 6 on which Amakusa is placed and a heater pipe 7, and the water injected from the water supply pipe 25 is heated by the heater pipe 7.
It is set up so that the Amakusa on top can be boiled.
More specifically, the strainer net 6 is formed to divide the inside of the pot 1 into upper and lower stages, and the heater pipe 7 is bent in a meandering manner below the strainer net 6. The heater pipe 7 is provided so that steam can be sent from a boiler (not shown) through a steam intake port 26 to boil water and boil Amakusa. By boiling water and generating steam in the pot 1 sealed in this way, an internal pressure higher than atmospheric pressure was obtained, and this internal pressure was used to send the broth to a filter (not shown).

[Problem that the invention attempts to solve]

However, as mentioned above, in the method of sending the broth to the filter using the internal pressure obtained by boiling Amakusa, the water in the pot is boiled by sending steam to the heater pipe. , thereby increasing the internal pressure. However, if this steam supply was not stopped at an appropriate time, more and more steam would be generated, creating too much internal pressure and risking the pot bursting.

On the other hand, in order to increase the internal pressure in this way, it is necessary to seal the pot. For this reason, the lid must be tightly tightened with locking bolts, but it is difficult to tighten the locking bolts evenly, and there are parts that need to be tightened more strongly. As a result, the packing in that area would deteriorate faster than in other areas, and there was a risk that the adhesion would be incomplete and the broth in the pot would spew out.

This invention is an attempt to improve the above-mentioned problems, and in other words, it eliminates the danger of the pot bursting or the boiling liquid spouting out from the damaged packing. Therefore, there is a problem to be solved in ensuring the safety of work when using the pressure cooker.

In other words, the present invention proposes that when sending broth from a pot to a filter, compressed air is sent into the pot to give an appropriate internal pressure inside the pot, which causes the pot to be exposed to an internal pressure that exceeds the allowable limit and burst. In addition to eliminating the danger, by inserting a packing into the flange ring on the main body side and providing the packing so that it can move forward and backward using compressed air, it is brought into close contact with the flange ring on the lid side with uniform pressure, thereby allowing the boiling liquid to spray out. The specific means and effects are as follows.

[Means for solving the problem] A compressed air intake is opened above the main body of the pressure cooker, and a hose extending from the air compressor is connected to the air intake.

An annular groove that opens toward the lid side flange ring is provided in the main body side flange ring, and the packing is inserted into the annular groove so that it can move forward and backward, and an air hole is bored at the bottom of the annular groove. Connect the hose extending from the air compressor.

[Effect]

Internal pressure can be applied by sending compressed air into the kettle from an air compressor. That is, the pressure necessary to send the broth to the filter can be obtained. Furthermore, by sending compressed air from an air compressor into the annular groove through the air holes, the packing can be brought into close contact with the lid with uniform pressure.

Further, in the inner cylinder 2a, 8 is a broth outlet, 9 is a pressure relief port, and 10 is a compressed air intake, all of which are connected to the outer cylinder 2b.
The inner cylinder 2a is provided so as to communicate with the outside by passing through the inner cylinder 2a. More specifically, the pressure relief port 9 is provided at the top of the pot 1, and is provided so that the pressure in the inner cylinder 2a can be released as necessary. Further, the compressed air intake port 10 is connected to the pot 1 in the same way as the pressure relief port 9.
The compressed air intake 10 is provided at the top of the
An air hose (not shown) extending from an air compressor (not shown) is connected to. That is, the compressed air produced by the air compressor is passed through the compressed air intake port 10 to the inner cylinder 2a.
It is installed so that it can be sent inside.

The lid 4 is provided to correspond to the opening of the inner cylinder 2a, and is formed so as to be able to seal the inner cylinder 2a via a packing 13. More specifically, flange rings 15 and 16 are welded to the outer periphery of the opening of the inner cylinder 2a and the outer periphery of the lid 4 so as to face each other, and flange rings 15 and 16 are welded to the outer periphery of the flange rings 15 and 16 at regular intervals. The engaging pieces 21 and 22 are attached so as to face each other. 14 is a clutch ring;
The clamping pieces 23 are fixed at regular intervals in correspondence with the engaging pieces 21 and 22, and the engaging pieces 21 and
22 so as to be rotatable. That is,

Next, its effect will be explained.

In a state in which the Amakusa is placed on the straining net 6 and the lid 4 is closed, the clutch ring 14 is rotated to cause the clamping pieces 23 to clamp the engaging pieces 21 and 22. In this state, compressed air from the air compressor is sent through the air hose 18 and the air hole 19 to the annularly formed groove 17, so that the packing 13 is tightly pressed against the flange ring 16 with uniform force. It is pressed, and the effect of sealing the inside of the inner cylinder 2a is obtained. Furthermore, after boiling Amakusa, the pressure (internal pressure) in the inner cylinder 2a can be increased by sending compressed air from an air compressor into the inner cylinder 2a through the compressed air intake port 10. This internal pressure allows the broth to be sent to the filter.

Amakusa can be boiled at an ideal temperature by interposing a solenoid valve in 6 and controlling the solenoid valve by a temperature sensor 30 provided in the inner cylinder 2a to limit the steam sent to the heater pipe 7. Furthermore, by setting this control temperature to approximately 120°C, boiling can be carried out without increasing the internal pressure. Incidentally, by keeping the pressure relief port 9 open, it is possible to prevent the internal pressure from increasing during the boiling operation.
