Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a filtering device for frying oil, particularly a disposable type of filtering device for frying oil.

(Prior Art) Conventionally, tempura has been designed to remove fragments of batter, oxides, moisture, etc. that get mixed into the tempura through use, using a filter element made by laminating a large number of disk-shaped filter papers. Oil filtration devices are well known and are disclosed, for example, in Japanese Utility Model Publication No. 32684/1983 proposed by the present applicant.

This known filtering device is made of an inexpensive material that is discarded after being used several times, such as a paper container body covered with aluminum foil, in which the filter element is fixed with a holding member, and is discarded after being used several times. It is offered as a type.

However, such filtration devices have disadvantages in that the container body must be disposed of together with the filter, which wastes resources and is still expensive.

(Problem that the invention aims to solve) This invention further reduces waste of resources by reducing the amount of parts to be discarded, and
The aim is to make it possible to provide it at a lower cost.

(Means for Solving the Problems) In order to solve the above problems, the means adopted by this invention is to form a filtrate outflow hole approximately in the center of a flexible thin sheet having a predetermined area; A filter element formed by laminating a large number of thin plate-shaped filter papers with filtrate passages penetrated is arranged on the sheet, the central filtrate passage is communicated with the filtrate outflow hole, and the peripheral side of the filter element is opened outward. It is characterized in that it is fixed onto the sheet with a holding member.

(Embodiments) Preferred embodiments of this invention will be described in detail below with reference to the drawings. In the figure, 1 is a sheet made of a suitable material such as cloth, paper, or resin, and is soft and flexible and has a required area. A filtrate outflow hole 2 is formed approximately in the center of the sheet 1 . Since the sheet 1 is disposable after one or two or three uses, oil resistance and durability are not required.
Also, it may be made of a material that is permeable to oil. In the illustrated embodiment, considering ease of manufacture,
Although the shape is square, it goes without saying that it may also be circular.

Reference numeral 3 denotes a filter element, which is made of a stack of many disc-shaped filter papers each having a center hole. In the stacked state, the center hole forms a filtrate passage 4 that vertically passes through the center of the filter element 3.
Create. The filter element 3 has, for example, an outer diameter of about 5 to 6 cm, a center hole diameter of about 1 cm, and a diameter of about 200 cm.
It has a height of about 1 cm by stacking sheets of filter paper.

The filter element 3 is arranged on the sheet 1 while the filtrate passage 4 of the filter element 3 is aligned with the filtrate outflow hole 2, and fixed and held by a holding member 5 so as not to lose its shape.

The retaining member 5 has a filter element 3 at its upper end.
It consists of a disc-shaped cover plate 6 that substantially coincides with the upper surface and covers the upper surface, and four belt-shaped mounting leg plates 7 that hang down from the cover plate 6, and the filter element 3 is covered with the cover plate 6. At the same time, the mounting leg plate 7 is fixed onto the sheet 1 while the filter element 3 is held within the mounting leg plate 7.

Note that the holding member 5 includes the covering plate 6 and the mounting leg plate 7.
It is not limited to those having the third,
As shown in FIG. 4, strip-shaped mounting leg plates 7 may be attached to the upper surface of the filter element 3 in a crisscross manner.

When the filter element 3 is held on the sheet 1 by the holding member 5, at least its circumferential side is opened outward, allowing used cooking oil to pass through the gap between the stacked filter papers. ,
Impurities in oil are removed by attaching them to paper fibers.

Referring to FIG. 5, a saucer 9 is placed at the mouth of the oil storage pot 8. The tray 9 is shaped like a cup and is made of metal such as aluminum or synthetic resin and has an open top and an opening 10 in the center. The sheet 1 holding the filter element 3 is inserted into the tray 9. wear. In the arranged state, the filtrate outflow hole 2 is aligned with the opening 10.

When used tempura oil 11 is put into the sheet 1 inserted into the saucer 9, large impurities such as pieces of batter contained in the tempura oil settle at the bottom, and float in the oil and settle. During passage through the filter element 3, impurities of small size that are difficult to remove adhere to the fibers of the element and are removed. After filtration,
The sheet 1 along with the precipitated impurities is removed from the receiving tray 9 and disposed of by incineration or the like.

(Function) Insert the sheet holding the filter element into the tray and pour in the used frying oil. Relatively large-sized impurities in the tempura oil are removed by precipitation, and small-sized impurities that are difficult to precipitate are removed by adhering to the fibers while passing through the interlayer spacing of the filter element. The frying oil from which impurities have been removed collects in the filtrate passage of the filter element, flows down through the filter outflow hole of the sheet, passes through the opening of the saucer, and is stored in the oil storage pot with the saucer disposed at the mouth.

After filtration, the sheet is removed from the tray and discarded together with the filter element.

(Effects of the invention) According to this invention, the sheet is made up of a sheet that holds a filter element, and is arranged in a suitable tray to filter the frying oil. Since only the sheet and the filter element are included, there are few parts to be discarded, which is beneficial for resource saving and can reduce costs.
