Description

[Detailed Description of the Invention] The present invention relates to an apparatus for frying food in oil in a short time and efficiently using microwaves.

When frying food in high-temperature oil by irradiating microwaves, the dielectric loss coefficient of the food is much larger than that of oil, so the microwave energy is selectively absorbed into the food, even thick foods. It has the advantage of being able to heat up to the center in a short time without burning the surface.

The food to be fried is heated submerged in the oil at first, or as the heating progresses, it floats up and the parts exposed to the air are not colored and cause uneven heating. You will need a presser net.

However, in fryer devices that use microwaves, the heating chamber is formed to prevent microwaves from leaking outside, so when loading and unloading food, it is necessary to open and close the door as well as to load and unload the presser net, resulting in poor workability. .

In order to eliminate these drawbacks, the present invention moves the microwave heating chamber back and forth to take in and take out food, and also attaches a presser belt to the microwave heating chamber, and this presser belt moves in conjunction with the movement of the microwave heating chamber. This paper proposes a microwave fryer device that improves the workability of loading and unloading food by driving the microwave fryer.

An embodiment of the present invention will be described below based on the drawings.

In the figure, reference numeral 1 denotes a microwave generator having a built-in magnetron, etc., which supplies microwave energy into a microwave heating chamber 3 through a waveguide 2.

4 is an oil tank which is kept at a constant temperature from the bottom using a heat source 5 such as gas.

The microwave generator 1 is placed on a rail 6 provided at the upper edge of the oil tank so that the upper part of the oil tank 4 can be moved horizontally, and the heating chamber 3 is moved horizontally within the oil tank at the same time as the device is moved horizontally. In addition, a microwave transmission net 8 is provided in the room to prevent the heated object 7 from rising, being located below the oil level.

Reference numeral 9 denotes a container used to take objects to be heated into and out of the oil tank, and the objects to be heated are stored and immersed in the oil tank.

At this time, the microwave generator is located at the left end in the figure, and the top of the oil tank is open.

After the container 7 is immersed in the oil tank, when the device is moved horizontally to the right, the heating chamber comes to the top of the container.

Since the object to be heated in the container has not yet been irradiated with microwaves, it has sunk to the bottom of the container, and therefore the net 8 is located below the oil level and above the container.

Next, when microwave heating is performed and the object to be heated is heated, it begins to rise, but the rise is restricted by the mesh, and the object to be heated does not float to the surface of the oil, so uneven cooking does not occur.

When the heating is finished, the generator is moved to the left again and the container is taken out from the oil tank along with the cooked food to be heated.Although the present invention has the above-mentioned configuration, the food to be heated can be taken in and out by simply moving the microwave generator horizontally. Therefore, work efficiency is improved without having to remove the net for holding down the heated object as in the conventional method.
