The present invention relates to a fryer having a refining apparatus, and more particularly, to a refrigerating apparatus having a float refining apparatus and a fryer having the apparatus for reusing and refining various solid sludge suspended solids and debris generated from waste cooking oil after one use. It is about.

Recently, due to the development of Western-style food culture, cooking oil is used a lot to prepare fried foods such as fried chicken and fast food. Generally, soybean oil and corn oil are used for frying in homes, chicken shops, and general food restaurants.In recent years, the so-called well being industry has attracted attention, and cooking oils are expensive, high-quality cooking oils such as olive oil and grape seed oil. I use a lot. Since the price of cooking oil is much higher than that of general soybean oil, the cooking cost of cooking oil occupies a considerable proportion in chicken shops and restaurants that use a large amount of cooking oil, and it is urgently required to use cooking oil to regenerate and reduce the cost of cooking oil.

Typically, a fryer used in a general restaurant injects new cooking oil into a tank of a fryer and repeats it several times (for example, about 60 to 80 times). It is oxidized by contact and is deteriorated due to carbonization due to the frying residue floating in the frying oil. As such, the amount of discarded cooking oil is considerable, which causes serious problems such as waste of resources and environmental pollution.

In view of these problems, several methods for purifying the already used cooking oil have been proposed.

That is, the oil is discharged through the opening and closing valve provided in the lower part of the fryer, which is the simplest and conventional method for refining the used cooking oil, and put the cooking oil in a separate container to settle the dregs and some cooking oil and use it again. However, this method takes a long time until the cooking oil heated to a high temperature cools down, there is a risk when handling hot oil and there is a limit to refining fine suspended matter, and some oils are discarded, resulting in waste.

Frying machine having another purification device for solving this problem is disclosed in Korean Utility Model Registration No. 20-0350422. When the fryer disclosed in Korean Utility Model Registration No. 20-0350422 is described with reference to FIG. 1, the support plate 12 is placed in a frying container 1 for injecting cooking oil, and a filter paper 5 is laid thereon and a blotter body ( 6) by using the filter paper (5) to prevent the flow of the filter paper, and the remaining oil discharge structure for the frying oil refining device of the structure to mount the removable strainer (7) detachable to the paper body (6) It is open. According to this device, when the edible oil used is poured into the strainer (7) placed on the top, it is primarily contained in the fry container (1) with a relatively large foreign substance filtered out, and the contained oil is driven by driving a separate oil circulation pump. The oil refining process is to pass through the filter paper (5) by the suction force to filter fine impurities. That is, this apparatus also adopts this method as a method of refining the oil once after the tempura cooking is completely finished and the restaurant is actually closed for a day.

However, the above-mentioned cooking oil refining methods can not be carried out because the process of frying cooking, that is, during the operation of the complex refining process and a lot of time, and is mainly performed at the end of business. Therefore, considering that carbonization is generated during frying cooking, once-a-day refining can only be seen as cleaning oil. Therefore, the debris generated during frying cooking remains in the oil as it is, which results in promoting oxidation of oil.

Floating matter generated during frying is oxidized in contact with air, and the floating matter is denatured to carbonization at high temperature (for example, 160 to 180 ° C), thereby actually accelerating oil rancidity.

In addition, the fine debris (carbide) present in the oil is stuck to the food is difficult to penetrate the heat source until the inside of the food has a problem that the outer surface of the fried food burns black even if it is not ripe.

In addition, filter papers used in cooking oil refiners are not only consumables for one-time use but also depend on the total amount of imports, causing environmental pollution and enormous foreign currency waste.

Accordingly, it is an object of the present invention to provide a float refining apparatus and a fryer having the apparatus capable of purifying the used cooking oil without replacing the filter paper.

Another object of the present invention is to provide a float refining apparatus and a fryer having the apparatus, which can purify cooking oil at any time during the operation in a restaurant or the like.

Another object of the present invention is to provide a float refining apparatus and a fryer having the apparatus, which can easily remove the floating matter (leave) remaining in the cooking oil at any time even during the frying process.

6 is a control flowchart for refining frying and oil according to a frying or refining mode according to an embodiment of the present invention.

2 to 6 will be described in detail the frying or refining operation of the basic embodiment of the present invention.

In order to cook the fried food, a preset amount of oil is introduced into the fried oil tank 22 and heated using a gas burner or an electric heater. When the temperature of the oil introduced into the frying tank 22 is heated above the set temperature, the frying food is added to cook the frying. When the frying is cooked in this way, the floating oil is generated in the frying oil tank 22 and fine residues (carbide) are produced to refine the oil injected into the frying oil tank 22.

When the refining / frying mode selection switch 34 is pressed to purify the oil, the controller 52 opens the electric ball valve 24 so that the oil introduced into the frying tank 22 falls into the refining tank 26. When all the oil injected into the frying tank 22 drops, the control unit 52 blocks the traditional ball valve 24. Oil dropped through the electric ball valve 24 is filtered by the filter media 46, the fine foreign matter. The filter mania 46 is made of stainless steel, for example, has a # 250 ~ 350 mesh structure. In the past, pulp-based filter papers were used, and when used more than once, the remnants passed through the cells and the refining function was lost. However, after the purification using the filter media (46) in the present invention can be used again when purified by washing and re-installation can be used semi-permanently. The oil refined through the filter media 46 is collected into a space formed in the filter screen 40. At this time, the control unit 52 operates the refinery oil pump 30. Then, the purified oil collected into the space of the filter media 46 is pumped by the refined oil pump 30 and supplied back to the frying tank 22 through the suction pipe 28 and the oil return pipe 32.

In this way, when all the oil is purified from the refinery tank 26 and the pumping is completed, the controller 52 stops the operation of the refinery oil pump 30. Then, when selecting the frying mode by operating the purification / frying mode selection switch 34, the oil filled in the frying tank 22 is heated again and food is added to perform frying cooking.

Thus, the frying operation or the oil refining operation according to the operation of the refining / frying mode selection switch 34 will be described with reference to the flowchart of FIG. 6.

In step 101, the controller 52 checks whether the power is turned on and proceeds to step 102 when the power is turned on. In step 102, the controller 52 checks whether the purification mode is selected from the purification / friing mode selection switch 34, and if not, the flow proceeds to step 103. In step 103, the controller 52 checks whether the frying mode is selected from the tablet / frying mode selection switch 34, and proceeds to step 104 when the frying mode is selected. In step 104, the controller 52 heats up the frying tank to perform the frying operation. However, when the purification mode is selected from the purification / frying mode selection switch 34 in step 102, the control unit 52 opens the electric ball valve 24 in step 105. When the electric ball valve 24 is opened, the oil in the frying oil tank 22 falls into the refinery oil tank 26. After that, the controller 52 checks whether the first set time (for example, one minute) has elapsed, and proceeds to step 107 when one minute elapses. In step 107, the controller 52 closes the electric ball valve 24 after one minute has elapsed since the oil filled in the frying tank 22 falls into the refinery tank 26. In operation 108, the control unit 52 operates the refined oil pump 30 to re-purify the refined oil collected in the space of the filter screen 38 through the suction pipe 28 and the oil return pipe 32. To supply. Then, in step 109, the controller 52 checks whether the set time (for example, 3 minutes) has elapsed, and proceeds to step 110 if the set time has elapsed. In step 110, the controller 52 determines that all of the oil filled in the refinery tank 26 has been purified and recovered to the refinery tank 22, and stops the operation of the refinery oil pump 30.

When the oil refining is completed, the filter medicament 46, the filter media support 48, and the filter screen 40 are separated and cleaned, and then mounted in the refining tank 26 again.

The refinery tank 26 is installed in the lower portion of the frying tank 22, and when pulled to the front is pushed forward along the rail not shown and pushed to the rear to be pushed backward along the rail not shown. The refining tank 26 is pushed back when refining the oil to be mounted to the inside of the fryer main body 20, and when the refining machine is cleaned, the refining tank 26 is pulled to the front to protrude out of the fryer main body 20. Be sure to

Conventionally, after frying has been finished, the restaurant is closed after cooking, and the cooking oil refining process is performed once, so that it is not possible to prevent rancidity of the cooking oil due to food floats generated during the frying operation. The frying machine equipped with the float removing device according to the present invention can remove food waste from time to time even during the frying cooking process, so that the cooking oil can be kept clean.

The description of the above embodiments is merely given by way of example with reference to the drawings for a more thorough understanding of the present invention, and should not be construed as limiting the present invention. In addition, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the basic principles of the present invention.

As described above, according to the present invention, since it is possible to easily remove the food floating matter (flours) generated during frying cooking without using a separate cooking oil refiner, it is possible to reduce the cost and environmental pollution caused by purchasing filter paper and refiner. .

In addition, the suspended solids refining apparatus of the present invention can be used semi-permanently for a long time using filter media made of stainless steel as well as easily removes the residues remaining in the oil during the cooking process. It can reduce the progress of cooking oil rancidity can significantly reduce the waste flow.
