Description

[Detailed description of the invention] [Industrial application field] This invention is a filtration device for frying oil, etc., and especially a filtration device that performs filtration processing so that dirty filters can be easily taken out without getting your hands dirty. Regarding.

[Conventional technology]

Conventionally, a filter element made of a large number of laminated thin disc-shaped paper filter bodies is placed at the bottom of the main container, and a filtrate passage that passes vertically through the center of the filter element is bored in the center of the bottom of the main container. The present inventor has proposed a filtering device for frying oil, etc., in which a disk-shaped compression plate having rod-shaped legs is placed on the top surface of a filter element and communicates with a filtrate take-out hole, and is inserted into a filtrate passage. It was proposed and opened in 1978.
-Disclosed in Publication No. 179075.

In such a filtration device, the filter elements are compressed by a compression plate and stacked in a dense state, and the central filtrate passage is substantially blocked by the compression plate placed on the top surface, so that the top plate is closed. The oil flows from the peripheral surface of the filter element toward the central filtrate passage, and fragments of batter from the tempura and carbonized black impurities are filtered out to obtain clean tempura oil.

[The problem that the invention attempts to solve]

In the above-mentioned filtering devices for frying oil, etc., when replacing the filter element, it is necessary to pick up the dirty filter element with the fingertips and remove it from the main container, which has the disadvantage that the fingers get dirty.

This invention eliminates these drawbacks and makes it possible to replace the filter element without getting your hands dirty.

[Means for solving problems]

In order to solve the above-mentioned problems, the method taken by the present invention is to arrange a filter element formed by laminating a large number of thin disk-shaped paper filters in the bottom of the main container, and to place the filter element in the center of the filter element. The formed filtrate passage is communicated with a filtrate extraction hole bored at the bottom of the main container, and a compression plate for compressing the filter element is placed on the upper end surface of the filter element, and the filtrate passage is inserted into the lower part of the compression plate. In a filtration device for tempura oil, etc., which has vertical legs and a knob installed at the top, the legs are formed by two elastic, narrow, dog-shaped plates spaced apart. The device is characterized in that the dogleg-shaped maximum expansion portion is slightly larger than the inner diameter of the filtrate passage and is located below the lower surface of the filter element.

〔Example〕

The drawings show a preferred embodiment of this invention, and in the drawings, reference numeral 1 denotes a main body container of the filtration device, which is made of an oil-resistant and odor-free material with an open top surface.

Filter element 2 is placed in the center of the bottom of container 1.
are stored and arranged. The filter element 2 is made of a large number of laminated disc-shaped filter papers with a central hole.
Form to a height of . When the filter elements 2 are stacked in this manner, the center hole forms a filtrate passage 3 that vertically passes through the center of the filter element 2.

A compression plate 4 having substantially the same diameter as the filter element 2 is disposed on the upper end surface of the filter element 2 . The compression plate 4 has a desired weight, and due to its weight and the head pressure of the stock solution contained in the container 1, the filter element 2 is compressed downward into a dense state. The compression plate 4 is made of a suitable material having desired rigidity and oil resistance, such as a metal plate or a synthetic resin plate.

A leg 5 is vertically provided at the center of the lower surface of the compression plate 4 and is inserted through the filtrate passage 3 passing through the center of the filter element 2 . The leg 5 is elastic and consists of two narrow plates 5a and 5b spaced apart from each other, and has a dogleg shape with a maximum diameter extending approximately one-third from the lower end. The maximum expansion portion 5c is located at least below the thickness of the filter element 2, and more preferably is located at a position passing through the filtrate extraction hole 7 bored in the center of the bottom wall of the container 1. Further, the maximum external dimension of the maximum expansion portion 5c is larger than the inner diameter of the filtrate passage 3 of the filter element 2. As a result, the filter element 2 is held by the inserted legs 5, and when the compression plate 4 is taken out to the outside, the filter element 2 can be taken out together. The legs 5 exert a wedge effect between the legs 5 and the circumferential surface of the filtrate extraction hole 7 and are pulled downward, thereby increasing the compressive force of the filter element 2. A knob 6 is installed in the center of the upper surface of the compression plate 4, making it easy to take out the compression plate 4, and by holding the knob 6 with your fingers, it is possible to minimize dirt on your fingers.

The filtrate outlet hole 7 at the center of the bottom wall of the container 1 communicates with the filtrate passage 3 at the center of the filter element 2, and the filtrate flowing down from the filtrate outlet hole 7 is transferred to an oil reservoir 8 detachably connected to the lower part of the container 1. can be stored in

At the time of filtration, after the container 1 is inserted into the upper part of the oil storage device 8, the used frying oil is allowed to flow into the container 1. The oil that has entered the container 1 passes through the laminated gap of the filter element 2, and impurities in the oil adhere to the paper fibers constituting the element 2 and are removed. The filtrate from which impurities have been removed passes through the filtrate passage 3, flows out from the filtrate outlet 7 into the oil reservoir 8, and is stored therein.

[Effect of idea]

According to the filtration device for frying oil, etc. of this invention, a filter element made of a large number of laminated thin disc-shaped paper filter bodies is arranged in the bottom of the main container, and a filter element formed at the center of the filter element is arranged. The filtrate passage communicates with the filtrate take-out hole bored in the bottom of the main body container, and a compression plate for compressing the filter element is placed on the upper end surface of the filter element, and a leg for inserting the filtrate passage is provided below the compression plate. Vertically installed,
In a filtration device for tempura oil, etc., which has a knob on the top, the legs are formed by two elastic, narrow, dogleg-shaped plates spaced apart, and The expanded part is made slightly larger than the inner diameter of the filtrate passage and is located below the bottom surface of the filter element, so by holding the knob and taking out the compression plate, the filter element can be held with the legs and held together. It can be taken out and there is no risk of getting your hands dirty when replacing the filter element.
