Description

[Detailed Description of the Invention] The present invention relates to a tempura frying pan equipped with a device that automatically adjusts the oil level of the tempura frying pan to a constant level.

Currently, tempura made from fish meat or the like as a main ingredient is mass-produced using an automatic fryer equipped with a conveyor 5 and a gas burner 6, as shown in FIG.

According to this automatic fryer, the oil level in the pan decreases over time due to evaporation of oil and frying with oil attached to the product (tempura). When it reaches a certain level, it will affect the way the tempura is fried.
Oil had to be replenished.

In contrast, at present, oil in cans or tanks is refilled manually or with pumps, etc. when the oil level drops to a certain extent due to human monitoring. According to this replenishment method, constant monitoring is required during operation. In addition, since a considerable amount of oil is poured at once, the oil temperature in the pot decreases, resulting in deterioration of the quality of the product and variations in product quality. .

In addition, other replenishment methods include a refueling device with electric level control or a refueling device with a float, but even if you try to apply these devices, because they use oil, they tend to attract dirt and may cause malfunctions. At the same time, the equipment needs to be heat resistant due to the high temperature.Furthermore, because it is structurally complex, it reaches high temperatures, and it is theoretically impossible to achieve automatic lubrication. However, there are many problems in terms of maintenance and management when adopting this in actual sites, and the current situation is that it is hardly used.

In other words, this project was researched and developed in view of the above-mentioned circumstances, and the purpose of this project is to automatically maintain a constant oil level with an extremely simple device that does not require manpower or power. The purpose is to provide a tempura frying pan equipped with an automatic oil level adjustment device.

Next, the present invention will be described in detail below based on an example of implementation shown in the drawings.

First, a sealed refueling tank 2 is placed at a position higher than the oil level a of the tempura frying pan 1, a refueling pipe 4 having a cock 3 is connected to the tank 2, and the open lower end 4a of the pipe 4 is connected to the By matching the position of the oil level a, an automatic oil level adjustment device is formed.

Here, as shown in FIGS. 3 and 4, the fuel tank 2 has a sealed structure that prevents air from entering from the outside in the closed state. In FIG. 3, the fuel tank 2 and the lid 2a are The opening lid 2a is tightened and fixed by the knob bolt 8 with an O-ring 7 interposed between the opening lid 2a and the fourth opening.
In the figure, a replenishment oil funnel 9 and an air vent 10 are provided on the upper surface of the fuel tank 2, and cocks 11 and 12 are provided on both 9, 10 and the fuel tank 2, respectively, to form a sealed structure.

In other words, the fuel tank 2 may have any structure as long as it does not allow air to flow in from the outside in the closed state and can be filled with replenishing oil, and is not limited to the embodiment.

Furthermore, it is preferable that the capacity of the refueling tank 2 is large enough to secure at least the amount of refueling required for one day (40' L in the example), and in this case, refueling during operation is unnecessary, reducing labor. This has the effect of making it possible to achieve this goal.

The refueling tank 2 is placed at a higher position than the oil level a of the tempura frying pan 1, and in this embodiment, as shown in FIG. In this case, it is preferable to have the tank 2 mounted on it, as it can respond to changes in the installation status of the tank 2 and changes in the setting position of the oil level a. It's good.

Next, the refueling pipe 4 has one end communicating with the refueling tank 2 and the other end opening downward.The lower end 4a of the opening is aligned with the set position of the oil level a, and the opening of the pipe The lower end 4a has two functions: sensing the height of the oil level a and supplying oil.

In addition, the tempura frying pan 1 of the present embodiment is a primary pan of a two-barrel automatic frying pan, and the primary pan 14 is provided with an overflow pipe 15 as shown in FIG. In this case, the oil level can be controlled without requiring any moving parts in both the primary pot and the primary pot.

Here, in the primary ladle 14, the reason why the oil level C rises is that the amount of oil brought in when the intermediate product is transferred from the secondary ladle to the primary ladle 14 is the amount that the product takes out from the primary ladle 14. This is because - primary pot 14 is larger than secondary pot 1.
This is because the temperature is set high, the viscosity of the oil is low, and the amount of product adhesion is naturally low.

The tempura frying pan 1 of the present invention can be applied not only to the automatic frying pan described above but also to a manual frying pan with only a pot.

Note that 16 in the figure is an oil confirmation window, and 17 is a lifting screw.

Therefore, when using the tempura frying pan of the present invention, first, the cock 3 is closed and replenishment oil is poured into the oil tank 2.

Then, the opening lower end 4a of the oil supply pipe 4 is brought into alignment with a predetermined oil level a.

Thereafter, the cock 3 is opened, the raw material d is put into the tempura frying pan 1, and the frying operation is started.

In this way, after a certain period of time has elapsed, the oil level a gradually decreases as the oil evaporates and is discharged with the oil still attached to the product.

However, if a space is formed between the opening lower end 4a of the oil supply pipe 4 and the oil surface a, the oil supply tank 2
Air enters in the form of bubbles and increases the internal pressure of the sealed space in the fuel tank 2, causing the pressure equilibrium to collapse and the replenishment oil in the tank 2 to flow out from the open lower end 4a of the fuel pipe 4. This is to raise the oil level a which has fallen.

Then, the lower end 4a of the opening is closed due to the rising oil level a, and if the replenishing oil in the oil tank 2 communicates with the oil in the tempura frying pan 1 and the pressure is maintained in equilibrium, the oil stops flowing in and out. This is to maintain the oil level a as it is.

If the oil level a further decreases, the replenishment oil in the oil tank 2 will similarly flow into the tempura frying pan 1 where the oil level a has decreased, and a large amount of replenishment oil will flow in at once. Therefore, the oil temperature in the frying pan 1 does not drop suddenly, and a constant oil level a can be maintained by adding oil little by little.

Since the present invention can be constructed and used as described above, it has the following effects.

(1) No other operations are required just by filling the refueling tank 2 with replenishing oil.

(2) Automatically refueling when the oil level a drops,
There is no need for constant human supervision.

3) Since the oil is supplied in small amounts, it does not have a significant effect on the oil temperature in the pan.

(4) Since there is almost no change in the oil level a during refueling or temperature change due to refueling, uniform and high quality fried products can be produced.

(5) There is no electricity, power, moving parts, consumable parts, etc., so there is no breakdown.

(6) Since the structure is extremely simple, it can be manufactured at low cost.
