Description

[Detailed description of the invention] The present invention is mainly used for commercial use of 7-layer, potato etc.
%, this type of fryer uses an electric heater to heat oil pipes for frying. Conventional fryers of this type have an electric heater and a 7-liter kettle. 1gm
The heat transfer efficiency between one heat source (electric heater) and the other oil is good, but the disadvantage is that it has a reverse shape - IIX
'hru.

(1) Add oil directly to the electric heater! ! +touch (
As a result, localized boiling occurs and the frying oil deteriorates very quickly.

(2-Electric heating - A carbonized film of oil is generated on the outer surface of the heater, and if this is not removed, the effectiveness of the heating will be greatly reduced, and there is a risk of serious injury. *S) A heater with poor workability. (3) Since the electric heater is a combustible material and is directly immersed in oil, strict preventive measures must be taken to control the heater to prevent it from igniting. (4) Since the surface of the fryer (heat exchange pole for frying oil) is small, the rate of heat transfer to the total amount of frying oil is slow, and the oil is heated up to the desired temperature f on average. It takes a long time to flea.

(51) The heat and the -ta swing in the frying oil, which hinders the handling of fried foods and may cause wire breakage.
There are also many electrical system problems such as switch failures.

The present invention was made in order to eliminate such conventional drawbacks, and its features are that an outer tip is installed in the fry kettle, and in this outer tip,
An inner tape 1 is provided which communicates with the inside of the 7 liters and into which oil can be introduced, and the connection between these turch crystals and the inner tape is electrically heated. This is done by installing a heater.

In other words, the original W! # Mine, electric heater [Outer Teou-
The frying oil pipe is covered with a deep-fried oil pipe and an inner pipe to heat the frying oil pipe indirectly. In addition, when using the indirect heating method, the heat transfer efficiency of the fryer to the oil will be lower than that of the direct heating method, but in order to compensate for this, the fryer in the fry kettle is introduced into the inner cheep of the oil pipe, and the stirrer is introduced into the oil pipe. The heat exchange between the outer tip and the inner tip is done not only on the outer circumferential surface of the outer tip but also on the inner circumferential surface of the inner tip. It is something that Furthermore, safety is improved by placing an electric heater in the gap between the outer tape and the inner tape.

In the following, the invention will be explained in detail with reference to the illustrated embodiments.

As shown in Fig. 1, this flyer has 1 machine frame as a whole.
It is installed inside.

As shown in FIG. 2, the fry kettle 2 is covered with the waste St insulation material 3 except for the upper part X1.

Inside this fry kettle 2, there are a plurality of (three in this example) outer tabs 4 with a perfect circular cross section between the front and rear walls.
... are suspended horizontally in parallel.The insides of these three outer chains have the same structure as shown below.In other words, as shown in Figures 2 to 4, each of the outer chains has the same structure.

Inside the tarp 4, an inner tape 5 having a perfect circular cross section and having the same length as the tarp 4 is arranged concentrically, and a liquid-tight gap 6 is formed between the two tapes 4 and 5. It is formed.

A large number of short communicating pipes 7 are cut through the shell between both the inner arches 4. It is connected to the inside of No. 2, and the frying oil inside can be introduced.

The communication pipe 7... is connected to the inner pipe 5't1.
- They are arranged at regular intervals in one direction of the axis on the lower side, and are arranged in the same way on both the left and right sides, and the arrangement of the lower part and the arrangement of the left and right sides are different. The inner cheeks 5 are offset in the axial direction 9, and the left and right inner sides are inclined upwardly with respect to the inner arch 5.

Within the above-mentioned barrier 116 and above it, several electric heaters 8 having a length spanning almost the entire length thereof are disposed.
Ru. These electric heaters 8 are automatically controlled by a control device (not shown) in a control box 9 disposed outside the fry kettle 2.

The structure of this fryer is as described above, and its function will now be described. The outer chain 4, the inner chain 15, and the communication pipes 7 are heated by the heat of the electric heater 8. .

When the frying oil in the frying kettle 2 is heated, it undergoes upward convection, so as shown in FIG.
Due to the flow of water into the inner arch 5, the arrangement relationship between the lower communication pipe 7 and the left and right inner communication pipes 7 is different as described above. The oil that has flowed into the inner tip 5 immediately flows through the communication pipes 7-φ on both the left and right sides without flowing out of the inner tip 5 and the outer tip 4. After flowing inside in the axial direction, it flows out from the communication pipes 7 on both the left and right sides so as to branch diagonally upward to the left and right.

Thus, while flowing in this way, the frying oil flows on the inner surface of the lower delay pipe 7, the inner circumferential surface of the inner tape 5, and the inner circumferential surface of the communication pipes 7 on both the left and right sides. The heat exchange action pipe receives and heats the oil, and at the same time heat exchange is also performed on the outer surface of the outer chip 4. In addition to being self-explanatory, the flow of oil into and out of the inner chain 5 as described above can improve the convection of the frying oil in the frying kettle 2 due to the flow of oil. Note that the outer nose tip 4 may have an elliptical cross section as shown in FIG.

As is clear from the above description, the seventh layer of the present invention has an electric heater, an outer tip and an inner tip.
Since the electric heater is wrapped in oil and heated in a uniform manner, the electric heater is heated in a heated manner.
The above-mentioned drawbacks of the conventional method, which directly heats the oil by dipping it into the oil, do not exist.

In addition, when frying in a 7-ray kettle, oil is introduced into the inner tape, and heat exchange with the oil occurs due to the outer tape.
1 In addition to I, the heat exchange is also carried out on the inner peripheral surface of the inner tape, so that the heat exchange efficiency is improved and the heat conduction rate relative to the total amount of oil is faster. Furthermore, safety is also improved because the barrier between the outer and inner ceilings of the electric heater is placed.

%, as in the embodiment described in claim 2, if a plurality of outer chimneys are installed horizontally in the frying kettle, and an inner chimney and an electric heater are provided in each of them, 7. Fried oil in a rice kettle can be heated evenly.

In addition, as in the embodiment described in section 3, the inner channel
Inside the pipe [and multiple connections penetrating between it and the outer pipe] (If you connect it with the inside of the fry kettle by Eve,
Furthermore, as in the embodiment described in Section 4, the frying oil in the frying kettle can be easily introduced into the inner tape. If placed below and on both the left and right sides between the outer and inner panels, the inner and outer panels will improve the convection of the oil. It is clear that even if a gas/(-) fire is introduced, it is possible to heat the oil pipe in the same way as when an electric heater is installed in the meantime.
