Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings showing an embodiment of a frying apparatus having a frying oil convection prevention kit of the present invention.

1 to 5, the frying device having the anti-convection kit of the present invention includes a case 1 with an open top, a frying tank 2 provided inside the case to accommodate the frying oil, and a frying tank inside the frying tank. A heater 3 in a form bent in a zigzag manner at a certain depth, a power connection part installed on one side top of the case 1 and connecting terminals on both sides thereof to external power supply terminals while supporting the heater 3 ( 5) and the convection prevention kit (6) provided in the frying tank to partition the frying oil accommodated in the inner space of the frying tank (2) into an upper layer (A) and a lower layer (B) and prevent convection of the frying oil in the upper and lower layers. ). Although not shown in the drawing, a grill in the form of a net is provided above the heater to keep the frying material put into the frying tank in the frying oil, but is omitted for simplicity of the drawing.

The heater 3 installed horizontally in the inner space of the frying tank 2 is heated to 220 to 240 degrees, for example, to maintain the upper portion (A) of the frying oil accommodated in the frying tank 2 at 170 to 180 degrees. controlled The operating temperature of the heater 3 is controlled by a control unit (not shown) installed in the contact connection unit 5 . A temperature sensor may be installed in the frying tank to set and control the frying temperature.

The lower part of the frying tank 2 is formed in a funnel shape, and a discharge part 7 opened and closed by a valve is formed at the lower end thereof.

According to the present invention, in the frying tank 2, the frying oil convection prevention kit 6, which kits a convection prevention means for preventing the convection of the upper part (A) and the lower part (B) of the frying oil, can be easily disassembled and installed in the frying tank Provided.

To this end, the anti-convection kit (6) includes a plurality of pipes (61) installed horizontally at the lower side of the heater (3) generally provided in the frying tank (2) as upper and lower brackets (64, 65). It is formed by connecting, and the frying oil of the frying tank is divided into an upper layer (A) and a lower layer (B) by the pipes 61, and the lower bracket ( 68) is supported.

The pipes 61 are spaced apart from each other to allow the fried batter debris normally generated in the frying process to move to the lower part of the funnel shape, but the upper part (A) and the lower part (A) of the frying oil partitioned by the pipes (61) ( B) to have a gap to prevent convection of frying oil to prevent mixing by convection, for this purpose, for example, 10mm ~ 20mm, preferably arranged to have a gap of 12mm ~ 15mm.

The cross-sectional shape of the pipes may be selected from among circular, rhombic, and hexagonal shapes in which the corners are disposed upward so as not to hinder the downward movement of the fried batter.

Both ends of each of the pipes 61 may be closed in a state in which an insulating material is filled.

Handles 67, both ends of which are fixed, are provided on the upper surfaces of two spaced apart ends of the pipes 61, so that the user holds the handles 67 and lower brackets 65 fixed to both sides of the inner wall of the frying tank 2. ), the bracket anti-convection kit (6) supported by both ends of the pipes can be easily separated from the frying tank, and in this way, the anti-convection kit (6) is removed from the frying tank to remove the frying oil adhering to the inner wall of the frying tank. It makes it easy to remove and clean, so that the inside of the frying tank can always be maintained cleanly.

As described above, according to the present invention, a plurality of pipes 61 are arranged in the frying tank 2 at intervals such that the battering residue can fall downward, so that the upper layer (A) and lower layer (B) of the frying oil in the frying tank Since the convection between them is prevented, the upper layer portion (A), which is directly heated by the heater 3, can be maintained at a normal frying temperature of 170 to 180 ° C. As it turned out, it was found that the temperature was maintained at a temperature of 70 ° C or less by only heat conduction through the frying oil between the pipes.

This has been shown to be proven by testing under the following conditions.

As the anti-convection kit (6), stainless pipes with a diameter of 76.3 cm are connected at a distance of 13 mm and installed in the frying tank. As a result of measuring with a thermometer at a distance of 2cm from the room, the tempura oil temperature was found to be 50℃, and when cooking, frying oil may flow through the pipes when tempura oil fluctuates as frying ingredients are put into tempura oil and taken out and turned over. Therefore, under the same conditions, that is, in the state of stirring the upper layer (A) with cooking utensils, the temperature was raised to 57 ° C in the area 2 cm directly below the pipes, and the adjacent lower layer ( B) showed 36 ℃.

This result is, according to the present invention, the convection phenomenon between the upper layer portion (A) and the lower layer portion (B) in which the frying oil performs the frying action in the frying tank by the pipes 61 as the anti-convection kit 6 is prevented or minimized is understood to follow. As the temperature of the frying oil in the lower layer (B) reaches 36°C to 57°C in this way, even if the fried batter falls to the upper surface of the pipes, it falls smoothly through the inclined surface of the upper side of the pipe and the gap between the pipes, forming a funnel shape at the bottom of the frying tank. Since it can be collected in a non-carbonized state in the part, the frying oil in the lower layer is kept relatively fresh and can be reused after removing the batter residues through a filter, thereby reducing the frying oil consumed in the frying device.

Since the temperature of the lower layer (B) of the frying oil in the frying tank is maintained at 36 ℃ ~ 57 ℃, rancidity of the lower layer (B) is prevented, and the frying oil of the lower layer (B) opens and closes the valve in the discharge part (7) because the batter is not carbonized. The frying oil can be reused by removing the residue through the filter.

The anti-convection kit according to the present invention is not used as a conventional cooling means, but can prevent convection between the upper and lower layers and maintain the temperature of the lower layer lower than the carbide formation temperature, so that maintenance costs are not required compared to conventional cooling means. Energy can be saved by preventing heat loss, and manufacturing costs can be greatly reduced because devices such as motors and fans are not required.

The frying device employing the anti-convection kit according to the present invention is particularly suitable for businesses that handle large amounts of frying, and is particularly suitable for businesses that are easy to install or disassemble in the frying tank (2), so that the cleaning of the frying tank can be done conveniently. It is possible to maintain and manage the frying tank cleanly in a large-capacity frying device.
