Description

Ultrasonic Fried Food System

The present invention relates to an ultrasonic frying system, and more specifically, by combining the ultrasonic generator using the oscillation frequency of the piezoelectric element and the magnetostrictive vibrating element with a circulating refiner to rapidly increase the temperature of the frying oil that is internally incorporated into the frying container. The present invention relates to an ultrasonic frying system that improves the frying efficiency and uses the reclaimed cooking oil to recycle and use it, thereby improving the quality and cost of the cooking oil.

A common frying apparatus that has been generalized is to heat the temperature of the oil from about 150 ℃ to about 400 ℃, and then the food is cooked by the heated oil, wherein the method of heating the oil using gas or electric energy The heat transfer mechanism is used, and the frying apparatus according to the gas system comprises a heating means provided at the lower end of the container filled with oil and a thermometer for measuring the temperature of the oil.

Then, a predetermined control device for controlling the fire extinguishing function of the heating means is added in accordance with the measured value of the thermometer.

After igniting the heating means through the control device, the temperature of the oil measured from the thermometer is continuously measured. If the temperature of the oil detected from the thermometer exceeds the reference value, the heating means is extinguished so that the temperature of the oil is within the standard range. To keep it in place. Therefore, when the temperature of the oil detected by the thermometer is less than the reference value, the control device performs the normal on / off switching control by instructing the ignition of the heating means.

As such, since the frying apparatus used in the prior art depends entirely on the heating means of the oil, not only does it take much time for the temperature of the oil to rise to the reference value, but also because of the viscosity of the oil itself, In this case, the oil is easily turbid, reducing the number of uses.

This is a food debris in the frying of the food is internalized in the container, which causes the problem that the food is not evenly cooked to reduce the taste of the food.

In addition, the present invention is based on a circulating cooking oil purifier, which is the applicant's pre-registered patent No. 10-0767750.

Its pre-registration technology is combined with a fryer to enable real-time purification, but a negative potential generator is installed in the fryer to improve its frying power, color, and oxidation even at a relatively low temperature. Connected with the connecting pipe line branched by the branch pipe and the first and second filter bodies, the cooking oil used in the fryer is used by filtering only oxide and impurities as needed, or maintaining the animal oil derived from chicken or other meat. And, by allowing us to purify the suspended solids, fatty acids, etc. to enable us to always provide a clean and delicious tempura, by circulating in the fryer to make it possible to purify in real time, there is a feature that is faster and more convenient.

Referring to the operation of the present invention made of such a structure as follows.

First, the present invention, as shown in the accompanying drawings, the fryer 2 is provided on the upper side and the control system 50 for controlling the operation of the device is installed on the other side.

Therefore, all the operations can be operated according to the control operation of the control system 50. First, a certain amount of cooking oil for frying in the fryer 2 is set, the temperature is set and the heating means 20 is heated to the set temperature if the device is turned on. do.

Of course, at this time, since the ultrasonic generator 22 using the oscillation frequency of the piezoelectric element and the magnetostrictive vibration element is installed in the fryer 2, the power consumption is reduced because the fryer 2 is set to a temperature lower than the temperature in the fryer. Not only can it be reduced, but it also significantly reduces the generation of oxides such as charcoal when frying foods.

This, in turn, is equipped with a magnetostrictive vibrator on the side of the frying vessel to radiate ultrasonic waves from the magnetostrictive vibrator together with the heating means, thereby weakening the viscosity of the oil due to the vibration energy so that the oil can be easily heated to obtain a fuel saving effect. It not only prevents the oil from becoming dirty due to the pulverization of food debris by vibration energy, and has the effect of improving the taste of food.

As a side effect, when frying foods such as chicken, they deeply penetrate into the inside of the food and are cooked from the inside so that the frying operation is possible and the frying time is significantly reduced, and the frying time is significantly reduced. Is made excellent.

When the ultrasonic transmitter has passed 50 ms according to the initial operation, the microcomputer generates a control signal according to the duty modulation through the port.

This reduces the duty ratio from 85%-50% to approximately 2.5%-0% for a certain time, and converts and outputs the voltage corresponding to the duty ratio through the converter.

The duty modulator changes the duty of the triangular wave according to the duty ratio and transmits the duty to the buffer unit.

The vibration of oil by the ultrasonic wave is to make food fast and evenly cooked through the principle of caption, wave principle, and particle surface increase including the principle of vibration.

In addition, through the above-mentioned principles, the reverse osmosis phenomenon in which food water does not fall out occurs, thereby lowering the oil content of the food to maintain its original taste, as well as reducing fuel consumption and debris oil for a long time. Will be.

On the other hand, in the present application to heat the frying apparatus through the gas method as an example, heating the frying bowl through a heating wire also does not deviate from the gist of the present invention, in this case the position of the ultrasonic transmitter is 25% line from the surface of the oil It does not have to be located in.

And although the method of driving the ultrasonic transmitter is described in the PWM method, even if the ultrasonic wave output 40KHz or more using a pulse wave method or an impulse method does not deviate from the gist of the present invention, of course, the ultrasonic transmitter 1㎡ One can be installed per unit to increase the effect.

If the frying oil continues to fry in the same manner as described above, or when there is a large amount of oxides or floats in the frying oil, the frying operation is stopped and the opening / closing valve 21 positioned at the lower portion thereof is opened to feed the frying oil into the bag filter 3. Drop supply.

In the cooking oil dropped on the bag filter 3, the oil and impurities are first filtered, and a part of the cooled animal fat is entangled and separated, so that the cooking oil falling on the lower oil hopper 4 maintains a relatively clean state.

In this case, the first filtered cooking oil may be immediately circulated in a fryer, or may be reused after being moved and passed through the first and second filter bodies 6 and 6 'positioned at one side.

In the case where the first filtered cooking oil is directly circulated, as shown in FIGS. 3 and 4, after passing through the pressure pump 5, one side opening and closing valve 53 of the branched pipe 51 branched. ), The other side is closed, and the pump is circulated and transferred directly to the fryer 2 along the pipe 8 ', or the pressurized pumps respectively installed through the branch pipe 41 at the bottom of the oil hopper 4. (5 ') by operating one side may be used to transfer to the top of the fryer (2).

In addition, if you want to circulate it and use it after refining instead of using it in real time, open and close the valve 21 at the bottom of the fryer 2 and completely discharge it. Then, new cooking oil is added and heated. The cooking oil filtered primarily through) is moved to the first and second filter bodies 6 and 6 'on one side of the body 1 through the pressure pump 5 through the low oil hopper 4,

While the moving cooking oil passes through the first and second filter bodies 6 and 6 ', the suction pump 7 at the rear end may be sucked and transported and stored to the upper oil storage tank 9.
