Description

[Detailed Description of the Invention] The present invention relates to an improvement in an apparatus for deep-frying foods by providing an oil layer on a water layer at the bottom of a frying pan and directly heating this layer with a heating tube.

Such a device is widely used as it has the advantage of allowing precipitates such as charcoal and food fragments generated during frying to settle from the oil layer into the water layer, thereby keeping the oil clean at all times and obtaining suitable fried products. ing.

However, although these benefits can be fully expected in short-time operations, when frying operations last for a long time, the oil layer that comes into contact with the water surface becomes hotter than the boiling point of water, and the water that comes in contact with it also becomes hotter. The oil gradually heats up due to heat conduction from the oil layer, eventually reaching a temperature above its boiling point and vaporizing.

This water vapor rises in the oil layer and ejects with a loud noise while splashing oil, causing extremely dangerous situations such as burns for workers.

In order to eliminate the above-mentioned drawbacks of conventional systems, the present invention efficiently cools the lower part of the oil layer in contact with the water surface during work, thereby reducing the temperature rise in the water layer due to heat conduction from the oil layer. This will be explained in detail below.

The drawing shows an embodiment of the present invention. In the drawing, 10 is a substantially rectangular frying pan body, with a drain cock 11 on the front plate 10a, an exhaust pipe 12 on the rear plate 10b, and a bottom plate 10b. Discharge pipes 13 each having an on-off valve are attached to the face plate 10C.

By injecting water into the frying pan body 10 from the top, a water layer A is formed at the bottom with the drain cock 11 at the level, and an oil layer B is also formed above it.

Above the middle of the oil layer B, a plurality of heating pipes 14 are arranged at appropriate intervals in the horizontal direction so as to penetrate from the front plate 10a to the rear plate 10b of the frying pan body 10.

A heating means 15 such as a gas burner is provided in front of the heating tube 14.

The high temperature fluid heated by the heating means 15 flows through the heating pipe 14, heats the oil layer B, flows into the exhaust pipe 12, rises inside the exhaust pipe 12, and is discharged to the outside.

Oil layer B is provided on the left and right side plates 10d and 10e of the frying pan body 10.
The center is the communication part 16 between the upper and lower layers A and B, and the upper surface 17a is located at the bottom of the .

Ventilation portions 17 and 18 are formed such that the portions 18 a are inclined toward the communication portion 16 .

This ventilation part 17.18 is formed such that its front side opens toward the front plate 10a of the frying pan body 10, and its rear side communicates with the exhaust pipe 12 of the rear plate 10b.
It is designed to allow ventilation.

Reference numerals 19 and 20 designate a large number of heat sinks protruding from inside the ventilation portions 17 and 18.

Note that 21 is a ventilation pipe having a triangular cross section formed just above the center of the communication portion 16, and penetrates from the front plate 10a to the rear plate 10b of the frying pan body 10 in the same way as the ventilation portions 17 and 18.

This ventilation pipe 21 functions to cool the oil and, in conjunction with the upper surfaces 17a and 18a of the ventilation portion 17.18, to prevent the occurrence of oil convection.

A wire mesh 22 is removably attached above the heating tube 14 via a locking portion 22a, and this wire mesh holds the food being fried in the oil layer.

Reference numeral 23 denotes a decorative plate attached at an appropriate interval in front of the front plate 10a (71) of the frying pan body 10.

Reference numeral 12 a denotes a partition wall formed from the rear of the heating tube 14 to slightly above it to prevent the high-temperature fluid flowing out from the heating tube 14 from flowing backward into the exhaust pipe 12 .

Since the device of the present invention has the above-described configuration, the heating means 1
5, the high-temperature fluid flows through the heating pipe 14 and heats the oil layer B through the heating pipe 14 while heating the exhaust pipe 12.
The gas flows into the exhaust pipe 12, rises inside the exhaust pipe 12, and is discharged to the outside.

In this way, the frying operation can be carried out when the oil layer B reaches a temperature suitable for frying.

By the way, if such frying work continues for a long time, the temperature of the lower part of the oil layer B will gradually increase. The heat at the bottom of the ventilation section 17.18 and the heat sink 1
9.20 to the outside to prevent the temperature rise in the lower part of the oil layer B.

In addition, since the ventilation pipe 21 is provided directly above the communication part 16 that communicates the oil layer B and the water layer A, the oil flowing toward the water layer A will always be cooled by the ventilation pipe 21 and will not reach the water surface. It not only effectively prevents the temperature of the oil layer B in contact with the oil layer B from rising, but also prevents the oil from flowing into the lower layer and prevents convection.

In this way, air is constantly flowing in the ventilation section 17.18 from the front plate 10a side of the frying pan 10 to the exhaust stack 12 on the rear plate 10b side due to the upward airflow in the exhaust stack 12 caused by the high temperature fluid. Of course, the flow is shaped like e, and since the partition wall 12a is provided inside the exhaust pipe 12 so that the high-temperature fluid flowing out from the heating pipe 14 is guided above the exhaust pipe 12, the high-temperature fluid is Since backflow to the lower part of the exhaust pipe 12, that is, to the exhaust port side of the ventilation section 17.18, is prevented, the heat is released more efficiently.

Further, during frying, sediments such as charcoal and food debris that are generated slide down the upper surfaces 17a and 18a of the ventilation parts 17.18 and fall from the communication part 16 to the bottom of the water layer A.
It can be removed to the outside from the discharge pipe 13 if necessary.

As explained above, according to the frying device of the present invention, the ventilation section is formed so that the center is the communication section between the upper and lower layers and the upper surfaces are inclined toward the communication section, and the ventilation section is formed directly above the communication section. A ventilation pipe is provided with one end passing through the exhaust pipe so as to be located below the oil layer, and a large number of heat sinks are provided protruding inside this ventilation part, and furthermore, the air flows out from the heating pipe into the inside of the exhaust pipe. Since the partition wall was provided so that the high-temperature fluid was guided upwards into the exhaust pipe, the heat at the bottom of the oil layer was efficiently dissipated through the ventilation section and the heat sink, and the high-temperature fluid flowing out from the heating pipe was directed downwards. Since there is no backflow, the released heat is effectively released from the exhaust stack to the outside.

Therefore, it is possible to reliably prevent the temperature rise in the lower part of the oil layer, and therefore also prevent the temperature rise in the water layer, so that the oil frying operation can be carried out safely.

In addition, since the ventilation pipe is installed directly above the communication part,
Oil flowing toward the water layer is always cooled by the ventilation pipes, which not only effectively prevents the temperature of the oil layer in contact with the water surface from rising, but also prevents convection and prevents high-temperature oil from flowing into the lower layer. It also has the practical effect of preventing

In addition, precipitates such as charcoal and food particles generated during frying slide down along the slope of the upper surface of the ventilation section and fall intensively from the communication section to the bottom of the water layer, making it easy to remove them.

Furthermore, since the structure is simple, this type of device can be provided at low cost.
