Description

Frying Machine

The present invention relates to a frying apparatus for frying foods, such as meat or vegetables, at an appropriate temperature. The present invention relates to a frying apparatus in which power consumption is reduced, and deterioration of the frying oil is prevented as much as possible, and the food is fried more deliciously. .

The frying apparatus is a frying apparatus of an indirect heating method in which the frying oil stored in the frying container is indirectly heated by the heated frying container by heating the frying container according to the heating method, and stored in the frying container through an electric heater. It is divided into the direct heating method of frying device that directly heats the frying oil.

Since the indirect heating method burns the flammable fuel to heat the frying vessel, it is very inconvenient to use, and it is difficult to control the heating temperature, so that the frying oil can be heated to an appropriate temperature and practically impossible to maintain it. It is easily deteriorated and results in a problem that food is fried in a bad way.

In order to solve this problem, a direct heating method using an electric heater as a heating source has been proposed. In the case of using an electric heater, when the frying oil is heated indirectly by the heated frying container, the frying oil stored in the frying container is heated. Since the heating time is excessively consumed and the practicality is greatly reduced, the electric heater is disposed inside the frying container so that the frying oil is directly heated by the electric heater. Such a direct heating method of frying is more widely used than the indirect heating method of frying in terms of convenience and temperature control.

In the conventional frying apparatus using a direct electric heater, since the frying oil is directly heated by the electric heater, a large temperature deviation is generated so that food is not fried evenly (the temperature is lowered farther from the electric heater). ), It takes a relatively long time before the frying oil is heated to an appropriate temperature as a whole.

In order to solve this problem, conventionally, the frying vessel is made of a material having excellent conductivity, and the frying oil is directly heated by the electric heater, and the frying vessel is indirectly heated by the heated frying oil, and the frying vessel is indirectly heated. The surrounding frying oil is then indirectly heated again. That is, the frying oil is directly heated by an electric heater while being indirectly heated by a frying container of a material having excellent conductivity, so that the frying oil is uniformly heated to an appropriate temperature within a relatively fast time.

However, when the frying vessel is made of a material having excellent conductivity, since high temperature heat energy is radiated to the outside over the frying vessel, heat loss is greatly generated and power consumption is increased. In addition, since the vortex is greatly generated throughout the electric heater and the frying vessel due to the temperature difference, the frying residue flows in all directions throughout the frying oil and is continuously heated (the vortex is largely generated). There was a problem.

Accordingly, the present invention has been invented to solve the above problems, the purpose of the present invention is to provide a frying apparatus in which power consumption is reduced, the deterioration of frying oil is prevented as much as possible, and food is more fried.

And a recovery container for temporarily storing the frying oil discharged from the first drain line is detachably built in the main body.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

According to Figure 1, the frying apparatus is equipped with a main body 100, components are installed, the main body 100 is provided with a frying vessel 200 for storing the frying oil, and the electric heater 320, the frying vessel ( It consists of a heating device 300 for directly heating the frying oil stored in 200. It should be noted that, in the present invention, the frying vessel 200 is made of a ceramic material separately from the main body 100, while the frying vessel supporting unit 110 supporting the frying vessel 200 is provided in the main body 100. )Wow ; A frying vessel protector 120 having a first drain line 130, which is spaced apart from the frying vessel by a predetermined interval while surrounding the frying vessel 200, is provided with a frying vessel 200. The recovery container 400 temporarily mounted and detachably mounted on the fry container support 110 in a state spaced apart from the 120 by a predetermined interval, and temporarily storing the fry oil discharged from the first drain line 130, the main body 100. Is detachably built-in).

According to the present invention, the heat loss is greatly reduced, the power consumption is reduced, the deterioration of the frying oil is suppressed and prevented, the food is evenly fried deliciously, as described in more detail as follows.

As is widely known, ceramics have a porous structure in which fine pores are formed, and this porous structure has a merit of low conductivity because it suppresses heat transfer. Therefore, when the frying oil 200 made of a ceramic material is filled with the frying oil and the electric heater 320 is operated, the frying oil is directly heated directly by the electric heater 320, and the electric heater 320. When the heating is started by the frying oil flows around the electric heater 320 by the temperature difference, the frying oil is heated to a high temperature as a whole by the electric heater 320. On the other hand, even if the frying oil is heated to a high temperature by the electric heater 320, since the frying vessel 200 of the ceramic material is gradually heated from the inner surface in contact with the frying oil to the outer surface, the high temperature thermal energy is frying vessel 200 Heat dissipation to the outside through) is suppressed as much as possible. In addition, even if the temperature of the outer surface of the frying vessel 200 rises, the separation space between the frying vessel protection unit 120 and the frying vessel 200 performs a heat insulation function, so that the heat discharge to the outside is blocked secondly, The heat loss is further reduced. Thus, when the frying oil is heated to a high temperature without heat loss to the outside, the power consumption for heating the frying oil is greatly reduced.

When the electric heater 320 is operated, the high temperature frying oil heated by the electric heater 320 has a relatively high temperature compared to the surrounding frying oil, and thus flows upwards, and the frying oil at low temperatures. It is flowed to the electric heater 320 in the downward direction, while the continuous rotation in the vertical direction is made to be continuously heated by the electric heater 320, wherein the frying oil located below the electric heater 320 Will remain almost stationary. In detail, the frying oil heated by the electric heater 320 circulates upward, and the inner surface of the frying vessel 200 is heated by the frying oil. Even if it is, the portion of the frying vessel positioned below the electric heater 320 is kept at a low temperature (remember that the ceramic has a very low conductivity). Even if the bottom surface of the frying vessel 200 is heated, the temperature of the bottom surface of the frying vessel 200 is circulated upward while the temperature of the frying oil continuously heated, or the upper portion of the frying vessel 200 heated thereby. Since it is relatively lower than the temperature, the laminar flow centering on the electric heater 320 maintains its shape. Therefore, the fried dregs that fall off when the food is fried are floating on the frying oil and moved to the bottom of the frying vessel 200, and the fried dregs moved to the bottom of the frying vessel 200 are placed on the inner bottom of the frying vessel 200. As mentioned above, since the oil for frying at the bottom of the frying vessel 200 maintains a relatively low temperature, the oil for frying is not easily deteriorated by the fritters.

In addition, when the frying oil is heated to a high temperature, thereby the frying vessel 200 is heated, when the frying vessel 200 is heated to a high temperature, far-infrared rays are emitted from the frying vessel 200 of a ceramic material to heat the high temperature Because it is quickly absorbed until the inside of the food is fried, the food is cooked evenly inside the food within a quick time to be delicious fried.

When repeated heat is applied to the frying vessel 200 of the ceramic material, cracks are generated in the frying vessel 200, and the high temperature frying oil leaks into the crack gap, or the frying vessel 200 is momentarily damaged. While there is a risk that hot frying oil is scattered in all directions, as shown in FIG. 1, the frying vessel 200 is spaced apart from the frying vessel protecting unit 120 by a predetermined interval in a state of frying vessel support 110. Removably mounted on the) to be fixed, and the frying oil leaked to the frying vessel protector 120 is discharged through the first drain line 130 to be temporarily stored in the recovery container (400).

In more detail, when the heating apparatus 300 is operated, the power supply control unit 310 is controlled to be "ON" by the control signal of the main control unit 340, and the electric heater is supplied from the outside. When the power is supplied to the electric heater 320, the electric heater 320 converts electrical energy into thermal energy to emit high temperature thermal energy to the outside, so that the high temperature emitted from the electric heater 320 is increased. The frying oil is directly heated by the heat energy of the frying oil. At this time, the main control unit 340 receives the temperature of the frying oil continuously through the temperature sensing unit 330 to set the frying oil temperature. Compared with the temperature lower than the oil temperature, when the temperature of the frying oil is equal to or more than the set frying oil temperature, the power supply control unit 310 is "OFF", the set frying oil temperature When lower than the figure, the power supply control unit 310 is kept in the "ON" state. Subsequently, after the food has been fried, the operation of the heating apparatus 300 is stopped by manually operating the input unit 350.

On the other hand, by giving a timer function to the heating device 300, after counting the elapsed time from the time when the power supply control unit 310 is first operated in the "ON" state, and compared with the set time, the heating device 300 Of course, it can also be turned off automatically after operating for only a set time.
