The present invention relates to a frying machine, and more particularly, to a frying machine capable of automatically refining cooking oil used for frying by providing an ultrasonic decomposition chamber and an oil refinery chamber in the fryer.

In modern times, western food culture has been introduced in Korea, and fried foods have become more frequent, and fried foods using cooking oil are increasing. Cooking oil usually uses olive oil and grape seed oil in addition to soybean oil and corn oil.

Normally, vegetable cooking oil used in fryer is composed of unsaturated fatty acids, which oxidizes well within a short time. The free radicals are generated by heat, light, and trace metals, and the chain oxidation of fats and oils proceeds to oxidize. Not only does the phenomenon progress rapidly, but the oil itself generates clusters (fat spheres) by high temperature heat, which makes the oil cloudy and more viscous. In addition, suspended solids by food ingredients are oxidized in contact with air and they are carbonized at high temperatures to accelerate oil rancidity.

Repeated use of cooking oil results in a large amount of cooking oil being discarded as animal fats and oils from food ingredients, impurities, residues, fatty acids, and oxides are mixed together, denatured and contaminated by carbonization of fried residues, making it impossible to reuse. . Since this is a waste of resources and acts as a factor causing environmental pollution, a fryer having a separate purification function has been required to solve this problem.

On the other hand, ultrasound means a frequency higher than the audible frequency band (20 ~ 20000Hz) that can be heard by humans, that is, 20 KHz or more, it is applied in many fields such as cleaning, processing, measurement, medical diagnosis. Ultrasonics have essentially the same properties as sound waves in the audible range, but generate very strong vibrations because of their high frequency and hence short wavelength.

When ultrasonic waves with a large amplitude are applied to a liquid, cavitation bubbles are generated, and when they grow and rupture, high-temperature and high-pressure shock waves are generated, which cause rapid flow or shear pressure. It is applied to various fields, such as a humidifier, an ultrasonic motor, an ultrasonic welding machine, and an ultrasonic therapy machine. In addition, the properties of the ultrasonic wave can be used to clean the surface of the object, the decomposition of the material, the catalyst of the metal plating process.

The hanger 23 prevents the fry from sticking to the catching net 21 by preventing the fry from falling directly on the catching net 21 forming the bottom surface where the fry is fried.

On the other hand, preferably, a ceramic ball-containing casing 27 filled with a ceramic ball 25 is preferably provided between the bottom of the oil storage tank 11 and the catching net 21. Ceramic, which is a material of, refers to materials such as oxide, nitride, and carbide, which use inorganic materials as the main raw materials. Such materials generally have corrosion resistance, heat resistance, and abrasion resistance compared to metal materials and organic materials. This is very large and has been applied to various industries (Fig. 2).

Ceramic ball 25 is a bio-ceramic ball, which emits far-infrared rays, which are beneficial to the human body, is manufactured by mixing ceramic powders that are widely known to be excellent in absorbing moisture and effective in removing odors and sterilization. It is produced by baking at high temperature.

When the ultrasonic wave is oscillated, the oil used inside the ultrasonic decomposition chamber 33 receives ultrasonic waves as a medium and is partially heated to generate small bubbles therein. This is called the cavity cavitation of the ultrasonic wave, and the material subjected to the ultrasonic wave due to the pressure when the bubble bursts and the discharge in the bubble undergoes a mechanical action or a chemical change. For example, emulsification is difficult to finely pulverized when subjected to ultrasonic waves to form a stable emulsion, and polymers and the like lose their bonds between atoms.

The strong vibration energy of the ultrasonic wave emitted from the ultrasonic oscillator 31 in the fryer is finely pulverized not only clusters (fat spheres) of oil that are difficult to be purified by a general filter present in the oil, but also hardly decomposable organic substances. This gives the effect of refining the oil used.

In addition, the lower portion of the rod is formed with a discharge port through which the refined use oil filtered by the cotton seal rod flows out.

In addition, the cotton thread rod constituting the secondary oil refining portion 43 is preferably made of a cotton thread twisted cotton yarn having a thickness of about 0.5 ~ 1 micro. The secondary oil refining unit 43 generates clean refined oil by removing the decomposed and used oil filtered by the fine wire mesh of the primary oil refining unit 41 by a cotton thread filter to remove fine suspended matter or residues present in the oil and deodorizing the odor. It has a role to make it possible.
