Description

High Efficiency Gas Fryer having Heat Conservation Bar}

The present invention relates to a fryer, and more particularly, the heating heat source uses a gas of LPG or LNG, and the oil tank containing the heating fluid can be contacted with the combustion gas so as to obtain the combustion heat from burning the gas to the maximum. The present invention relates to a high-efficiency gas frying machine configured to maximize the contact surface to heat the heating fluid more effectively and prevent rapid temperature change of the heating fluid.

Fried foods are widely used in homes and restaurants since they have a wide selection of ingredients such as fish, meat, and vegetables, and are relatively simple to cook. Recently, the cooking is more specialized due to the increase of fast food and chicken restaurants. The situation is massizing.

Such cooking is a relatively simple cooking method of cooking by pouring the cooking oil into the oil tank and putting the fried ingredients while heating, in general, a simple one using an oil tank and a frying net to heat the oil was 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 cooking time of oil are very important in the fried cooking method of cooking foods fried in oil. For example, fried chicken cooking method of cooking fried chicken in heated oil is known as oil. It has been argued that heating at 165 ° C for 10 minutes is ideal for cooking. 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, the frying apparatus mainly used to date is that the heating tube is formed in a straight pipe shape so that the heat of combustion passes quickly, resulting in a low heat transfer efficiency, and thus a long time to heat the oil and a low fuel efficiency. There is this.

In order to solve the above disadvantages, the fried chicken cooking device (registration 10-0654362) configured to bend the passage of combustion heat and a frying apparatus (registration 10-0822434) and a gas fryer for improving heating efficiency (registered patent 10- 10). 0866494) has been proposed, but the thermal efficiency is still up to 55%, so the present invention has been devised to obtain higher thermal efficiency than the above method.
