Description

Indirect heating soup pot {Indirect heating type caldron}

The present invention relates to a soup pot, and more particularly, to an indirect heated soup pot capable of preventing food from being burned or pressed by heating the lower portion of a large capacity pot evenly by heating the heat medium oil and maximizing the taste of the food. will be.

In general, large-capacity soup pots are used to cook soup, stir-fry, and deep-fry in large restaurants.

The soup pot is a steam heating type of indirect heating method that injects a gas-heated soup pot and steam (steam), which is a direct heating method for directly heating the soup pot by burning fuel such as gas, into a cavity between the inner and outer shells of the pot.

Gas-heated soup pots are burned due to accidents caused by gas leakage and heat concentrated on parts of the soup pots, and the discomfort that the cooks must stir with a spatula until cooking is completed, the risk of burns due to heat, and the gas burning furnace There is a problem such as dizziness caused by the decrease in oxygen concentration in the air and the increase of carbon monoxide.

On the other hand, an indirect heated soup pot using steam (steam) has been developed and used.Because the soup pot using steam (steam) is cooked while the boiler and steam generating steam are put in the inner and outer shells to warm the pot. It is preferred because it can overcome all the problems of the direct heating using gas.

However, the indirect heating type soup pot using steam (steam) is more efficient than the direct heating type because it heats up the pot and wraps the entire pot, so it requires extra steam boiler and piping to deliver steam. Not only does it cost a lot, but it also requires a lot of space to install these things.

In addition, heat loss occurs in the process of transferring heat to water to make steam in the boiler, and when steam generated in the boiler moves to the soup pot and safety valves are installed to prevent excessive pressure, Heat loss due to steam is generated.

In addition, steam may be condensed in the pot, and a water hammer phenomenon may occur in which condensed water generates a sound when passing through a pipe.

Accordingly, the present invention, in order to solve the problems presented above, in the soup pot consisting of the inner shell and the outer shell, the inner shell and the outer shell is welded and sealed as a hydraulic molded, the cavity between the endothelial and the outer shell is filled with heat medium oil By heating the heating medium oil directly by the heat transfer unit, the heated heating oil wraps the inner skin of many soup pots, thereby increasing the thermal efficiency and providing a simple soup pot which does not require a separate steam boiler and complicated piping.

In addition, by using a heat medium oil having a low expansion rate and a high boiling point, it is possible to provide a soup pot capable of high temperature and low expansion and safety.

Indirectly heated soup pot of the present invention for solving the above problems in the soup pot consisting of the inner shell and the outer shell, the inner shell and the outer shell is welded and sealed as a hydraulic molding, the cavity between the inner shell and the outer shell is filled with heat medium oil, The outer shell is provided with a protruding portion downward, and a heat transfer portion is provided therein, a drain hole is formed at the lower side of the outer shell, and an inlet is formed at the side of the outer shell.

The thermal oil is a petroleum mixture having a low expansion rate and a high boiling point.

In addition, a safety valve is connected to the inlet port to prevent the air or the thermal oil contained in the thermal oil from expanding and increasing the pressure to damage the junction between the inner skin and the outer skin.

The present invention has an advantage for a simple cooking pot because it does not require a separate steam generating boiler and piping as an indirect heated cooking pot to raise the temperature of the heat medium oil filled in the cavity between the inner skin and the outer shell to cook by heating the inner skin.

In addition, since the thermal oil used has a low expansion rate and a high boiling point, it can be heated to a high temperature, allowing fast cooking and various high-temperature cooking in addition to soup, as well as reducing heat loss to the outside and increasing safety.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

1 is a block diagram of an indirect heated soup pot according to an embodiment of the present invention, in the soup pot consisting of the inner shell 10 and the outer shell 20, the inner shell and the outer shell is welded and sealed as a hydraulic molded, the inner shell and The heat medium oil 30 is filled in the cavity between the shells at all times, and the shell is provided with a protrusion 21 at the lower side and a heat transfer portion 40 therein, and a drain hole 22 is formed at the lower side of the shell. The inlet 23 is formed on the side of the shell.

In addition, a safety valve 50 is further connected to the inlet.

Hereinafter, an operation relationship will be described in more detail with reference to the drawings.

The soup pot is composed of the inner shell and the outer shell, the joint between the endothelial and the outer shell is welded and sealed, a protrusion is formed below the outer shell and a heat transfer part is provided therein.

In order to prevent rust and harm to the human body, the inner skin is hydraulically formed by a high pressure hydraulic press using a material such as stainless 304, so that beautiful molding is possible without welding, and the surface is cleanly finished by polishing after molding.

On the other hand, the outer shell may be used in general, but stainless steel may be used in consideration of thermal deformation, and like the inner shell, it is hydraulically formed by a high pressure hydraulic press, and cuts the bottom center portion of the molded outer shell and welds the protrusions. do.

The inner shell and the outer shell are welded with argon to form a national pot with a highway. The resulting highway is filled with thermal oil, and the thermal oil is heated due to electric heat applied to the heat transfer unit. The heat medium oil is preferably a mineral oil-based mixed oil capable of heating up to a high temperature is low expansion of the volume and high boiling point even when heated.

The heated heat medium oil is in contact with the lower end of the endothelium as a whole to transfer heat, the transferred heat is to cook food, including soup in the soup pot.

Since the heat medium oil may be heated to a high temperature, foods using a soup pot may also be cooked, such as stir-frying and frying, which require a high temperature.

On the other hand, even if the thermal fluid having a low thermal expansion rate is used, since excessive expansion of the air contained in the thermal fluid may occur, and an internal pressure may be excessively generated, a safety valve 50 may be connected to the inlet to control the maximum pressure. The safety valve may be a check valve that can be finely adjusted.

In addition, the inlet port 23 is connected to the inlet port for exchange or replenishment of the heat medium oil, and the switching valve 70 is installed at a predetermined portion of the inlet pipe to open the valve when the inlet of the heat medium oil through the inlet pipe, and cooking It is normally closed, including the hour.

The heat transfer part 40 is in direct contact with the heat transfer oil so that heat generated by the heat transfer portion is transferred to the heat transfer oil without loss, thereby minimizing heat wasted. On the other hand, by installing the temperature sensor 60 in the highway to measure the temperature of the heat medium oil to control the temperature required for cooking by the control unit and the current breaker of the power supply, display the temperature value measured by the temperature sensor or inlet pipe You can also check the temperature of the heat medium oil by attaching a thermometer on one side.

In addition, the control unit may be connected to the operation unit for setting the cooking temperature and cooking time and a timer.

In addition, since the heat medium oil may be deteriorated when used for a long time, in this case, the heat medium oil needs to be exchanged, thereby forming a drain port at the bottom of the outer shell to discharge the heat medium oil.

As described above, by controlling the electricity applied to the heating unit according to the set temperature or time suitable for the object to be cooked, heat of the optimum condition can be transferred to the soup pot through the heat medium oil, thereby reducing heat loss as well as food. It can also increase the taste.

In addition, due to the heating of the heat medium oil by the electric heat transfer unit using electricity, a pipe for using steam and a separate steam generating boiler, etc. are not necessary, so the installation structure is simple and the mobile installation is easy.

As described above, the present invention has been described based on the preferred embodiments with reference to the accompanying drawings, but it will be apparent to those skilled in the art that various obvious modifications are possible without departing from the scope of the present invention.
