Description

Frying device equipped with a function to suppress the occurrence of bequest {FRYER FOR RESTRAINING OCCURRENCE OF OIL MIST}

The present invention relates to a frying apparatus, and in particular, to a frying apparatus having a conjugation suppression function to ensure a safer and more comfortable cooking environment by suppressing the occurrence of oil due to moisture in food materials.

In food service establishments, frying oil is used to cook fried foods such as chicken and tempura. There are various types of frying oil, but it is common to use vegetable oil, and it is generally referred to as edible oil.

On the other hand, in catering establishments, a method of cooking using gas by putting edible oil in a container of a fryer is commonly used, and used edible oil is simply recycled or separated and purified in a separate storage container and then reused.

When a food ingredient is fried through cooking oil, water molecules in the food material may be mixed into the oil, resulting in a beacon, and the likelihood of such a beacon may increase rapidly in proportion to the number of times the cooking oil is reused. The bequest is fatal to the health of the eyes and lungs and acts as the biggest contaminant of the cooking space.

When such a coating layer 110 is used, it has a far-infrared emissivity of 90 to 95%, and has a non-adhesive property, which is a property that contaminants are not impregnated, and fried powder or food does not stick well to the floor, and the frying container (100) has the effect of increasing the acid resistance, corrosion resistance and stain resistance.

The bequest suppression device 300 includes a discharge plate 310 inserted into the frying container 100, and generates electronic micro-vibration for selectively evaporating only the moisture in the food material, thereby eliminating the cause of the bequest. To be.

For reference, when ingredients are added to a frying dish and heated, moisture, that is, water molecules in the ingredients are mixed into the frying oil. Then, the water molecules are heated and decomposed by the heat of the frying oil, and the oxygen molecules are charged negatively (-), and the oxygen molecules at this time are combined with the molecules of the frying oil that are charged as positive (+), which is a later effect.

At this time, the purification container 510 is preferably provided on the lower side of the frying container 100, which is due to a height difference between the purification container 510 and the frying container 100 when the discharge valve 540 is opened. This is to allow the oil in the frying container 100 to be automatically discharged to the refining container 510 without a separate pump.

As shown in FIG. 3, the refining filter 520 is a sieve 521 that catches large debris contained in the frying oil, and a microscopic refining filter 520 that once again catches fine debris contained in the frying oil that has been first refined by the sieve 521. It can be implemented in a double structure with a special filter 522. That is, in the present invention, the impurities present in the frying oil are doublely removed through the refining filter 520, so that the oil is extracted and re-injected into the frying container 100 compared to the conventional one. In this case, the micro-special filter 522 is preferably implemented to filter impurities having a size of 5 μm or more, but a specific implementation method thereof may be variously changed according to the application environment of the device.

The discharge plate 310 is made of a conductive material, and the shape of the discharge plate 310 is preferably implemented in a plate shape as shown in FIG. 5, but the specific implementation shape thereof may be variously changed as necessary.

In addition, as shown in FIG. 6, by installing an insulating member 340 having an insulating property capable of discharging static electricity of a predetermined voltage in a space around the discharge plate so as to be adjacent to the discharge plate 310, The possibility of electric shock, the possibility of corona discharge, and the possibility that an external physical shock is directly applied to the discharge plate 310 can be prevented in advance. At this time, it is preferable that a plurality of holes are additionally formed in the power saving member 340, in order to minimize the convection phenomenon of the frying oil being disturbed by the power saving member 340.

The insulating property of the insulating member is determined according to the size of the electric field generated by the discharge plate 310. That is, the insulating member does not completely insulate the discharge plate, but at least the material and thickness are determined so as to discharge static electricity of a voltage necessary to form an electric field capable of directly applying a voltage of a target value to the object.

According to the discharge plate driving unit 320 configured as described above, the current generated on the secondary coil N2 side by the feedback control circuit 322 is fed back to the primary coil N1, so that the number of turns is small. It is possible to obtain a high voltage on the furnace secondary coil N2 side.

Further, the feedback control circuit 322 and the output circuit 323 are configured to cause a delay in the circuit, and as a result, electromagnetic micro-vibration is applied to the output of the secondary coil N2.

Due to this, the discharge plate 310 generates electromagnetic micro-vibration, and the vibration is transmitted to the surrounding space of the discharge plate 310 as waves, so that the discharge plate 310 does not have a ground electrode, and the discharge plate 310 has an insulating material. Is installed, the static electricity discharged from the discharge plate 310 is widely propagated to the space around the discharge plate 310 by this wave, and an electric field of a predetermined voltage is formed in the space around the discharge plate 310 do.

When the electric field of a predetermined voltage is formed in this way, the water molecules and the frying oil cannot be combined with each other due to the influence of micro-vibration within the electric field range, and only the water molecules are heated and evaporated. As a result, moisture present in food ingredients is heated and evaporated independently without being combined with frying oil, and as a result, there is no bequest due to moisture in food ingredients.

In addition, the thermal conductivity of the frying oil is increased by the electromagnetic micro-vibration generated by the beautifying device 300, and in this case, the temperature of the center and the surface of the food is uniform, so that the low-temperature cooking time is shortened, and the amount of oil absorption of the food material can be minimized. have.

In addition, as shown in FIG. 7, the apparatus for suppressing the bequest according to an embodiment of the present invention confirms the amount of frying oil based on the weight of the frying oil or the level of the frying oil through the sensor 350 and the sensor 350 It may further include a voltage control unit 360 for adjusting the voltage applied to both ends of the primary coil N1 according to the amount of fried oil.

At this time, the voltage control unit 360 includes at least one of a voltage boosting circuit and a voltage dropping circuit, through which the voltage applied to both ends of the primary coil N1 can be increased or decreased in proportion to the amount of fried oil.

That is, based on the correlation between the preset frying oil and voltage, by adjusting the voltage applied to both ends of the primary coil N1 by reflecting the currently sensed amount of frying oil, the secondary coil N2 and the output circuit 323 Through this, the intensity of the electronic micro-vibration applied to the discharge plate 310 is varied, and accordingly, the range of the electric field can be varied.
