Description

[Detailed Description of the Invention] The present invention relates to a hot liquid circulation boiling device for cooking boiled and fried foods by forcibly circulating a liquid heat medium such as boiling water or heating oil.

In general, when cooking noodles, for example, it is preferable to boil them at a constant temperature and in a constant stream of hot water, and when frying foods, it is best to fry them in oil at a constant temperature. This is a necessary condition for obtaining cooked products with good taste and other qualities.

However, in conventional cookers of this kind, the circulation of heat medium such as hot water or hot oil is not done in an orderly manner, and the thermal efficiency is not good, resulting in irregularities in the finished product.

In addition, noodles in particular cannot be solved well, so workers have to boil them or forcefully pass them through or loosen them several to dozens of times in or out of boiling water using other utensils. That's where I'm going.

This involved considerable danger and also had low work efficiency.

In view of the above-mentioned points, the present invention allows cooking to be carried out using hot water or hot oil at a constant temperature, has high thermal efficiency, and can be done in a sufficiently safe manner by anyone.
The purpose is to provide a hot liquid circulation boiler that can produce high-quality cooked products, and its gist is that the upper half of the outer tank contains a liquid heat medium such as cooking water or oil. An open inner pot is housed with a space provided between its periphery and an outer tank, and the inner pot is provided with a flow path that communicates with the inside and outside of the inner pot around the entire upper edge of the inner pot, and is placed under the inner pot. A heater having a liquid heat medium flow path penetrating vertically in the outer tank is housed therein, and the periphery of the heater except for the bottom is covered, and a space is provided between the heater and the inner surface of the outer tank. The hot liquid circulation boiler is provided with a circulation path regulating plate whose upper end communicates with the center of the bottom of the inner pot.

Next, an example of implementation of the present invention will be described with reference to the drawings.

In the figure, 1 is the main body of the hot liquid circulation boiler.

The main body of the boiler houses an inner pot 3 which has a vertically communicating opening in the center of an outer tank 2 that accommodates a heat medium made of oil or hot water.

The inner pot 3 is installed with a gap between its outer peripheral wall and the inner wall surface of the outer tank 2, so that a heat medium can flow inside and outside the inner pot 3.

Approximately U-shaped channels 4, 4... are formed at equal intervals on the upper edge of the inner pot 3.
... is formed, and the heat medium flows through the flow paths 4, 4...
・Through it, it is possible to flow in and out of the inner pot 3.

The bottom of the inner pot 3 is narrowed to a small diameter, and a bottom opening 5 is formed in the center thereof, and a circulation path regulating plate 7 is attached to the bottom opening 5 continuously.

The circulation path regulating plate 7 is open at the bottom and has a cylindrical expanded portion 8, and a space is provided between the outer periphery of the expanded portion 8 and the inner surface of the outer tank 2.

A heater 9 is housed in the expanded portion 8, and the circumference of the heater 9 except for the bottom is covered with the regulating plate 7.

The heater 9 penetrates the outer tank 2 and is inserted into the circulation path regulating plate 7, and houses a flame injection type burner 10 therein. l
'l... is formed.

In the figure, 12 is an exhaust pipe, 13 is a gutter for overflow drainage, 14 is a drainage path communicating with the overflow drainage gutter 13, 15 is a cleaning fluid supply path, and 16 is a heat exchange between the drainage fluid and the cleaning fluid. This is a heat exchanger that performs

In addition, in the above-mentioned embodiment, the channels 4, 4 are provided around the entire circumference of the upper edge of the inner pot 3.
. . . is formed, but only in favorable cases is the flow path 4.
4... may be formed to direct the flow of the heat medium in the upper part of the inner pot in one direction.
A plurality of bottom openings 5 may be provided, and a circulation path regulating plate may be connected to each of them, and the bottom openings 5 may also be biased toward the surroundings, and the shape thereof is shown in FIG. 3. Appropriate shapes such as a circular shape 5a, a rectangular shape 5b, a square mouth 5C, and a square shape shape 5e which is a combination of these can be used.

In the hot liquid circulation boiler configured as described above, when the heat medium housed in the outer tank 2 is heated by the heater 9, it is guided to the circulation path regulating plate 7 and is passed through the bottom opening 5 of the inner pot 3. rise,
Heat the books or fried food in inner pot 3.

Most of the air flows from the upper flow passages 4, 4, etc. to the inner pot 3 without causing a convection phenomenon in the inner pot 3.
It is swept outside, passes between the inner pot 3 and the outer tank 2, reaches the lower part of the heater 9, is heated again and rises, and rises when it is inside the inner pot 3 and falls when it is outside. However, in the upper part of the inner pot 3, a radial horizontal flow is formed from the center toward the periphery of the inner pot, resulting in a constant and orderly circulation.

The present invention is constructed as described above, and includes an inner pot housed in an outer tank, a flow path communicating inside and outside formed at the upper edge of the inner pot, and a cylindrical circulation path with an open bottom opening. By making the regulating plates continuous and housing the heater within the circulation path regulating plates, a constant flow in the upward direction is always formed in the inner pot, and the rising heat medium does not descend within the inner pot. , and descends through the outside of the inner pot. Therefore, the food is always cooked under constant flow and temperature conditions, and the quality is always constant, and the thermal efficiency is good, especially when it comes to noodles. This eliminates the need for safety and workability.
