Description

Induction heating frying apparatus using thermal plasma {FRYING APPARATUS OF INDUCTION HEATING TYPE USING HEAT-PLASMA}

The present invention relates to a frying apparatus, and more particularly, it is possible to heat the frying oil quickly and uniformly by using a thermal plasma, and to recycle and recycle the frying oil used, and the vapor and trans fatty acids and benzopyrene and It relates to an induction heating frying apparatus using a thermal plasma to minimize the occurrence of such harmful substances.

Modern people prefer fried food because of the crispy texture of the surface tissue created by dehydration during the frying process, the soft taste and unique aroma of absorbed fat, and the convenience and speed of busy life. Due to the rapid development of fast food (Fast food).

These fried dishes are widely used in general homes and restaurants because they have a wide selection of ingredients such as various fish, meats and vegetables, and can be cooked relatively easily. It is more specialized and massified.

In addition, a relatively simple cooking method of cooking by pouring cooking oil into an oil tank and putting frying ingredients while heating is used. In general, a simple tank using an oil tank and a frying net has been used. In order to meet the situation of more specialized and mass-produced businesses, the temperature control is possible and the supply of oil is automatically developed and used.

The frying apparatus widely used up to now includes a burner for supplying combustion heat, and a heating tube for heating the oil by transmitting the combustion heat of the burner to the oil by contacting the outer surface with oil and passing the heat of the burner to the oil. It is configured to include.

It is well known to those skilled in the art that the temperature and the cooking time of oil are very important in the fried cooking method of cooking foods fried in oil. It is claimed that cooking oil for 10 minutes by heating the oil to 165 ° C is ideal.

In fact, when food is fried and cooked, it is cooked by adding frozen or refrigerated food. During this process, cold food is added to absorb heat as the oil absorbs heat, and thus the temperature of the oil must be quickly maintained. If the oil temperature drops below the proper temperature due to refrigeration or frozen food input during the cooking process, the inside of the food may not ripen. If the cooking time is extended to compensate for the low temperature, the surface of the food may be crispy. The problem is that not only the taste is reduced but also the productivity is reduced.

In addition, when the large amount of food is continuously fried, the oil is always kept heated to a high temperature, so it takes little time for the food to be fried, but when the food is intermittently fried, the cold oil Since it takes a long time to heat to high temperature, there is a disadvantage that the productivity is significantly reduced.

However, since the frying apparatus mainly used up to now has a heating pipe formed in a straight pipe shape, the heat of combustion passes quickly, and thus the heat transfer efficiency is lowered, thus not only takes a long time to heat the oil, but also lowers fuel efficiency. There are disadvantages.

In addition, the heating source of the conventional frying apparatus is a direct heating method, that is, a frying bin is provided on the upper side of the main body of the apparatus, a heating wire is provided on the bottom surface of the frying bin to provide the frying oil introduced into the inside of the tubular body by the hot wire. By heating, the temperature of the frying apparatus increases, so that the working environment is poor, especially in the summer, this problem is further increased.
