Description

Tempura cooking device {FRIED COOKING APPARATUS}

The present invention relates to a frying cooking device.

In general, a frying cooking device using oil is widely used to cook ingredients such as french fries, whole chicken, and onion rings.

The frying cooking device is designed to cook by simply heating oil to boil and fry ingredients.

A conventional frying cooking apparatus includes a hollow tubular cooking container for receiving oil for frying and cooking ingredients, and a heater provided inside the cooking container to heat the oil contained in the cooking container.

Accordingly, when a certain amount of oil for frying is accommodated in a cooking container and power is applied to the heater, the heater generates heat and heat exchange with the oil for frying is performed.

After a certain period of time, when the oil for frying reaches a certain temperature, the user puts the ingredients in a cooking container and fries the ingredients to cook.

However, since the oil used in the conventional frying cooking apparatus is heated to a high temperature, when used for a long time, it is oxidized or scattered to form fatty acids harmful to the human body.

In particular, in the process of frying, frying residues generated by the frying ingredients settle on the bottom of the oil receiving part or float and burn together with fatty acids, causing oil to be easily contaminated and rancid.

Therefore, in the conventional frying cooking apparatus, the process of removing burnt frying residues generated during the frying process is very cumbersome, and it is not easy to maintain the oil at the standard level of rancidity. It needs to be replaced afterwards, and not only requires a lot of cost, but there is also a problem in that it is expensive to treat the replaced waste oil.

A drain pipe valve 93 for opening and closing the drain pipe 91 is attached to the drain pipe 91.

Accordingly, the drain pipe valve 93 is opened, and the oil 100 that has reached the end of its life can be discharged and collected to the outside through the drain pipe 91.

With this configuration, a description will be given of a process of heating and cooking food materials using the frying cooking apparatus according to an embodiment of the present invention.

First, all the valves are closed, and the vacuum generator 70 is set so that the cavity 13 of the cooking container 10 has an appropriate pressure.

Next, the first valve 27 is opened and the heater 30 is operated to heat the oil 100 contained in the cavity 13 of the cooking container 10.

Subsequently, when the oil 100 heated by the heater 30 reaches the set temperature, the container lid 21 is opened, the food to be heated and cooked is put into the cavity 13, and then the container lid 21 is closed. .

Then, after the first valve 27 is closed, the vacuum pump 75 of the vacuum generating unit 70 is operated and the valve 73 for an air discharge pipe is opened to open the cavity 13 of the cooking container 10. The ingredients are cooked by heating while maintaining the pressure close to the preset vacuum. At this time, the return pipe valve 63, the first return pipe valve 67, the second transfer pipe valve 69, the first valve 27, the second valve 49, and the connecting pipe valve 83 are closed. Maintain the state.

When the heating and cooking of the food is completed, the air discharge pipe valve 73 is closed, the recovery pipe valve 63, the first transport pipe valve 67 and the second transport pipe valve 69 open, and the cooking vessel 10 The oil 100 accommodated in is recovered to the oil recovery tank 40 through the recovery pipe 61.

When the oil 100 of the cooking container 10 is completely recovered to the oil recovery tank 40, the recovery pipe valve 63 and the second transfer pipe valve 69 are closed, and the first valve 27 is opened, The cavity 13 of the cooking container 10 is released by vacuum.

Subsequently, the container lid 21 is opened, and after the heated and cooked ingredients of the cavity 13 are taken out, the container lid 21 is closed again.

Then, the first valve 27 is closed, the second valve 49, the first transfer pipe valve 67, the second transfer pipe valve 69 and the air discharge pipe valve 73 are opened, and the vacuum pump 75 ) Is operated, the cavity 13 is generated at a pressure close to the vacuum, and the oil 100 stored in the oil recovery tank 40 is filtered through the filter 50, and the cooking container ( Return to 10).

When the oil 100 is sufficiently conveyed to the cooking container 10, the first conveying pipe valve 67, the second conveying pipe valve 69, and the air discharge pipe valve 73 are closed.

Then, after checking the temperature of the oil 100 returned to the cooking container 10, the first valve 27 is opened and the food is heated and cooked by starting again in the above-described order.

On the other hand, while food is cooked by heating in the cooking container 10, the housing lid 45 of the oil recovery tank 40 is opened, and the filter 50 is accommodated in the oil recovery tank 40 to filter the oil 100 After replacement or cleaning, the housing lid 45 is closed again, and the second valve 49 is also closed at the same time.
