Description

Oil fryer equipped with a circulation system to remove foreign substances and moisture

The present invention relates to an oil fryer equipped with a foreign substance and moisture removal circulation system, and more particularly, a foreign substance and moisture removal circulation system comprising a particle filtration unit capable of filtering foreign substances in frying oil and a centrifugal separation filtration unit capable of removing moisture in frying oil It relates to an equipped oil fryer.

The content described in this section merely provides background information on the present invention and does not constitute the prior art.

There are many ways to cook food, and the fry-style cooking method in which food is fried in oil is a common cooking method all over the world. As a rule, food is prepared in hot oil, liquid fat or in a deep pan, the temperature of which is usually 130 - 200 degrees Celsius. For commercial purposes, many styles of oil fryers are used around the world.

On the other hand, fried dishes are often coated with dough, eggs, breadcrumbs, or several layers of deep-fried food in order to retain the crispy texture and moisture of the food. Many fried foods are frozen products offered by producers and stores. One characteristic of this frozen food is that the surface of the food contains moisture in the form of ice.

In the case of fried food, a part of the food itself is separated during the cooking process, and some of the coating, crumbs and water are generated, which contaminates the oil in the oil reservoir of the oil fryer. These contaminants sink to the bottom of the frying pan, chemically accumulate and react with the high-temperature fortified oil, generating harmful DPTG (Di and Poly Triglycerides) and free radicals, where they begin to oxidize. Oils with a DPTG contamination of 16% or higher are considered a health hazard, and several government agencies around the world have guidelines and laws on this to determine how often to replace commercially used fryer oils.

In addition to DPTG contamination, there are other chemical reactions that reduce the quality and taste of the oil, such as the formation of fatty acids through temperature reactions.

When using an oil fryer, there are two main factors that affect operating costs. One is energy (gas or electric power), the other is the replacement of the frying oil itself. The amount and volume of food being fried and the temperature and amount of coating used on the food will determine the rate of oil contamination. The oil change interval depends on the level of contamination of the oil, which is a significant factor in the cost of running a restaurant. Most oil fryers have a volume of 5 to 50 liters, and some large commercial food processing plants use fryers with a capacity of 300 liters or more.

The cost of replacing frying oil is very high and harvesting/producing new oil and disposing of used frying oil have a very negative impact on the environment. The oil fryer from which impurities are removed by the filtration system can provide users with healthy food that is free of harmful substances to the human body. .

As mentioned above, many oil fryers have a cold zone where food deposits collect under the bottom of the fryer basket to remove impurities. Typically, the heat source is above this cold zone (ie gas heating tubes or electric heating coils), which can also slow the process of burning sediments into hazardous materials. However, in reality, such a cold zone does not function properly due to a circulation phenomenon, and even if it functions normally, it only delays the combustion process of impurities, and many and small impurities still float in the oil.

As mentioned above, in order to solve the problems of the conventional oil fryer, some domestic and foreign related companies have conducted research on oil fryers with a circulation system, but for actual commercialization, it is consumed in order to have a circulation system structure. If the cost is excessive, or even if it is not, there was no case of commercialization due to the lack of market competitiveness compared to the conventional oil fryer because the filtering effect of impurities in frying oil was not large compared to the manufacturing cost of the device.

Therefore, it is required to develop an oil fryer device capable of solving the problems of the prior art as described above.

The problem to be solved by the present invention is to supplement the above-mentioned disadvantages of the prior art, and the object of the present invention is as follows.

First, an object of the present invention is to provide an oil fryer equipped with a foreign substance and moisture removal circulation system that can effectively remove impurities accumulated in the frying oil by the cooking process by filtering foreign substances and moisture contained in the frying oil.

Second, it is an object of the present invention to provide an oil fryer equipped with a circulation system for removing foreign substances and moisture that does not require a cold zone in the oil storage unit by removing sediment and food particles in the oil storage unit through a circulation system equipped with a high-efficiency filter.

Third, an oil fryer equipped with a circulation system for removing foreign substances and moisture that can filter out foreign substances and moisture by separating the filtration unit that can filter foreign substances and moisture to increase the filtration efficiency and measure the real-time status information of the filtration unit by the sensor unit to notify the appropriate replacement time of the filter would like to provide
