An introduction pipe 8 is provided for supplying the container 7 from the bottom of the thin box body 3.
This relates to a frying pan with a filtration device in which a return pipe 9 for returning filtrate is provided and a pump 6 is disposed in the middle of the return pipe 9.

The purpose of the present invention is to provide a filtration device that has a small amount of residual liquid, allows easy filter replacement, can perform continuous and efficient filtration without taking up much space, and does not cause a drop in the temperature of the filtrate.

The present invention will be explained in detail below using examples.

The thin box body 3 has a thin box shape that is vertically flattened and is open at the top.

A bottom periphery punching plate 13 having numerous holes is fixed slightly above the bottom 12 of the thin box 3, and a protrusion 10 is provided vertically at the center of the short side of the inner wall of the thin box 3.
A plurality of (
In the illustrated embodiment, two protrusions 11 are provided, and a bottom protrusion 14 having a width equal to the width of the protrusion 10 protrudes from the center of the bottom circumferential punching plate 13.

The punching side plate 15 has countless holes, and the punching side plate 15 is inserted through the upper opening of the thin box body 3, and the front and back of the punching side plate 15 are provided with protrusions 10 and 10, respectively, as shown in FIG. Projection 11. It is supported by the bottom protrusion 14.

Here, the punching side plate 15 is shown in FIG. 4, but in FIG. 4, many holes are omitted.

The filter 2 is formed of any filter material such as filter paper, filter cloth, or net, and has a thin box shape that is flat in the vertical direction and has an outer flange 1 at the upper opening.

The filter 2 is inserted into the thin box 3 from above so that it can be taken out freely, and when the filter 2 is inserted into the thin box 3, the filter 2 is supported by the punching side plates 15 on both sides, and the filtrate is removed. The flow pressure prevents the filter 2 from expanding laterally.

A flange 16 is provided at the upper opening of the thin box body 3, so that when the filter 2 is inserted into the thin box body 3, the outer flange 1 of the filter 2 is placed on the flange 16.

A lid 5 is attached to the top of the outer flange 1 via a packing material 17 to cover the upper opening of the thin box 3. By attaching the lid 5, the outer flange 1 covers the lid 5 and the upper opening of the thin box 3. It is held by a flange 16 provided at the edge.

One end of an introduction pipe 8 passes through the lid 5, and one end of the introduction pipe 8 is located at the upper opening of the filter 2.

The other end of the introduction pipe 8 is inserted into the container 7 containing the filtrate.

In the illustrated embodiment, the thin box body 3 is of a stationary type and is supported by legs 19 having a base 18.

A discharge pipe 20 projects from the bottom 12 of the thin box body 3, and one end of the return pipe 8 is connected to the discharge pipe 20, and the other end of the return pipe 8 is connected to the container 7 containing the filtrate.

A pump 6 is provided in the middle of this return pipe 8.

Oil is put in a frying pan used as this container 7, and the pan is heated by a burner.The ingredients are put into the oil and fried foods are made one after another.At this time, the pump 6 is activated. The oil in the container 7 is sucked up through the introduction pipe 8 and is then poured into the filter 2 through the upper opening of the filter 2.
It is supplied to the punching side plate 1 after being filtered through the filter 2.
5 to the bottom circumference punching plate 13 to the filtrate distribution section 4, and is returned to the container 7 through the return pipe 8 from the discharge pipe 20.

In this way, by circulating and filtering the oil as a filtrate during the frying process, fries can always be made in a state free of impurities.

On the other hand, when the filtration operation is stopped, since the filter 2 is thin and box-shaped, the filtrate inside the filter 2 is quickly returned to the filtrate distribution section 4 and the return pipe 7, so there is little high-temperature residual liquid.
There is no problem in removing the lid 5 immediately, and therefore, removing the lid 5 and replacing the filter 2 can be done in a short time.

Furthermore, when the punching side plate 15 becomes clogged, it can be pulled out upward and cleaned.

In the illustrated embodiment, the center of the thin box 3 in the long side direction is curved outward to form a convex curved portion 21, but this serves to reinforce the thin box 3 and at the same time The introduction pipe 8 can be easily introduced by widening the center of the opening.

In the illustrated embodiment, a stationary type is shown, but the thin box 3 may be provided with a hook so that it can be hooked onto a container.

In the present invention, as described above, a thin box-shaped filter having an outer flange at the top is inserted into the thin box so that it can be taken out from above, and a lid is removably attached to the top of the thin box. Since the outer flange is clamped between the upper opening edge of the thin box body, the filter can be reliably supported by the clamping, and when replacing the filter, the filter can be removed by holding the outer flange with the lid removed. The filter can be easily removed from the thin box for replacement, and when removing the filter, it can be removed by holding the outer flange, which has the advantage of not getting your hands dirty. Also, the filtrate can flow between the outer circumferential surface of the filter and the inner wall of the thin box. The top of the thin box is covered with a lid, an introduction pipe is provided to supply the filtrate in the container to the upper opening of the filter, and a return pipe is provided to return the filtrate to the container from the bottom of the thin box. Since the pump is placed in the middle of the pipe, not only can the filtrate in the container be circulated and filtered continuously, but it can also be used when the amount of filtrate in the filter is small and the filter is overflowing. Even if the filtration process is stopped, only a small amount of residual liquid remains in the filter, which has the advantage that the filter can be replaced quickly. It has the advantage that the filter can be replaced safely because no residue remains, and since it is a circulation type filtration using a thin box-like filter, the filtrate can be filtered quickly and the temperature can be maintained even when the filtrate is at high temperature. It has the advantage of no deterioration.

Furthermore, since it is a thin box that is flattened in the vertical direction, it requires less installation space, and because it is thin and box-shaped, it can take up a wide filtration area and has the advantage of excellent filtration performance.

Moreover, since a pump is installed in the middle of the return pipe, suction and return can be performed with one pump by reducing the pressure inside the thin box, and at this time, the reduced pressure forces the filtrate into the filter. This has the advantage that there is no risk of foreign matter getting into the pump and there is no risk of pump failure, and that forced circulation allows for faster filtration work.

Note that if the thin box is protected with a heat insulating material, the temperature drop will be further reduced.

In particular, the viscosity of edible oil changes significantly depending on temperature, so the filtration ability of the filter at low temperatures decreases significantly.
According to the present invention, by forming the filter into a thin box shape, the filtration area is increased, thereby reducing the resistance of the filter, and the suction pressure of the return pump is used to suck up oil through the introduction pipe to pass through the filter. Since I sucked in new oil from the container as much as I did,
This has the advantage that there is no risk of damaging the filter due to excessive pressure being applied to the filter, clogging the filter, or reducing filtration performance and causing foreign matter to get caught in the pump.
