Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a fruit juice extraction method and a fruit juice extraction apparatus for separating and expressing fruit juice from fruits such as apples.

[Prior Art] Conventional fruit juice extraction methods and fruit juice extraction devices can be roughly divided into small-scale ones used at home and large-scale ones used in factories.

In the case of small-scale products used at home, the fruit is pretreated by cutting it into pieces of appropriate size, and then fed into a device to be ground, and the juice is extracted by centrifugation.

On the other hand, for large-scale products such as those used in factories, the fruit is crushed as it is, then put in a strainer and squeezed, or the juice is squeezed under pressure using a single-screw compression method.
Alternatively, the juice is squeezed using a decanter.

[Problem to be solved by the invention]

In the case of the small-scale apparatus as described above, there is a problem in that the fruit is pretreated and then fed into the apparatus, which is time-consuming.

In addition, since the juice is squeezed out by centrifugation after being ground with a juice extracting device, not only do tiny pieces of skin and pulp get mixed into the juice, but the time required for squeezing takes a long time, leading to deterioration of the juice in the process. There was a problem that nutrients were lost. Furthermore, since the structure of the device is complicated, there are problems in that it is troublesome to dispose of the squeezed residue and to clean the device.

On the other hand, in the large scale machines mentioned above, since the fruit is crushed as is, the skin, core, seeds, etc. of the fruit are crushed and mixed into the fruit juice, and there is also the problem that it takes a long time from crushing to the end of juicing. There was a point.

As a result, there have been problems in that the taste of the fruit juice is impaired, deterioration of the fruit juice is caused, and nutrients are lost.

Therefore, the purpose of this invention is to express fruit juice easily and in a short time without pre-processing the fruit such as crushing or cooking, and to extract the skin, pulp, and juice effectively, which was difficult with conventional techniques. To provide a fruit juice extraction method and a fruit juice extraction device that allow for effective separation and extraction, yet have a simple structure.

[Means to solve the problem]

The invention described in claim 1 [hereinafter referred to as claim (1)]
In the invention, the fruit is placed on a perforated plate having a large number of perforated holes, the fruit is crushed by a pressing member of a pressing device, and the pulp of the fruit is removed from the bottom or outside of the perforated plate. The structure is such that the fruit juice is squeezed out through compression.

The invention described in claim 2 [hereinafter referred to as claim (2)]
[Abbreviated as invention]] is a first small hole plate in which a large number of holes smaller in diameter than the small holes in the first small hole plate are formed through the lower side or outside of the first small hole plate. A second perforated plate is arranged, the fruit is placed on the first perforated plate, the fruit is crushed by the pressing member of the pressing device, and the pulp of the fruit is placed on the lower side of the first perforated plate. Alternatively, the fruit is compressed and penetrated to the outside, and the second perforated plate receives the pulp, the pulp is held between the first and second perforated plates, and the pressing member presses the pulp to separate the juice, pulp, and epidermis. The configuration is such that they are separated from each other.

The invention described in claim 3 [hereinafter, claim (3)]
[Abbreviated as the invention]] comprises: a perforated plate disposed in a fruit receptacle and having a large number of perforations formed therethrough; a fruit juice outlet provided at a position below the perforated plate of the fruit receptacle; The fruit is arranged above the perforated plate in the receptacle, and includes a pressing member that presses the fruit against the perforated plate to crush the fruit.

Invention set forth in claim 4 [hereinafter referred to as claim (4)]
[Abbreviated as the invention of]] comprises a first perforated plate disposed within a fruit receptacle and having a large number of perforated holes formed therethrough; a second perforated plate having a larger number of holes smaller in diameter than the perforated holes of the perforated plate, and a fruit juice outlet provided at a lower position of the second perforated plate of the fruit receptor; disposed above the first stoma plate within the fruit receptor;
The fruit is configured to include a pressing member that presses the fruit against the first perforated plate and crushes the fruit.

[Operation] Regarding claims (1) and (3), a fruit, for example, an apple, is directly placed in a fruit receiver and placed on a small hole plate. Then, the apple is pressed against the perforated plate by the pressing member of the pressing device and crushed.

When an apple is pressed against the perforated plate, the epidermis first ruptures, and the pulp enters the perforations of the perforated plate and moves downward while being compressed. At this stage, the skin and pulp are separated, and the juice contained in the pulp is separated and taken out from the juice outlet.

Regarding claims (2) and (4), the first fruit, for example, an apple, is directly put into the fruit receptor.
Place it on the small hole plate. Then, the pressing member of the pressing device presses the apple against the first perforated plate and crushes it. When the apple is pressed against the first perforated plate, the epidermis first ruptures, and the pulp enters the perforated hole and is compressed downward. Move to. In this first perforated plate, the apple skin and pulp are separated, and the pulp eventually reaches the second perforated plate.

Since the second perforated plate allows only the fruit juice to pass through and not the pulp, the pulp accumulates between the first perforated plate and the second perforated plate. On the other hand, since the pulp continues to be compressed from the first perforated plate, the pulp is further compressed between the first perforated plate and the second perforated plate, and the juice is squeezed out.

As a result, the epidermis remains on the first perforated plate, and the pulp remains on the first perforated plate.
The fruit juice remains between the perforated plate and the second perforated plate, and the fruit juice is taken out from the lower fruit juice outlet. That is, the skin, pulp, and juice are each effectively separated and taken out.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 7. Note that this embodiment will be explained as follows.

(A) About the first embodiment (B) About the second embodiment (C) About the third embodiment (D) About the fourth embodiment (E) About the fifth embodiment (A) About the first embodiment The figure shows a longitudinal sectional view of the fruit juice extraction device, and FIG. 2 shows the longitudinal sectional view of the fruit juice extraction device in a state where fruit juice is being squeezed out.

In the configuration shown in FIG. 1, the fruit juice extraction device is mainly composed of a frame 1, a pressing device 3, and a fruit receiver 6.

The frame 1 defines the overall external shape and size of this fruit juice extraction device, and a pressing device 3 is attached approximately at the center.

The pressing device 3 moves the pressing plate 4 up and down using the rod 2' of the stress linear conversion device 2. A rod 2' is disposed inside the casing 3' of the pressing device 3, and the casing 3'
A retaining groove 30 for fixing the fruit receptacle 6 is formed below '. In addition, this Okalinia conversion device! 2 only needs to be able to move the push plate 4 up and down, and any of electric, pantograph, pneumatic, and hydraulic power may be used.

The fruit receptor 6 has an opening at the top and has a generally cylindrical shape as a whole. The upper end of the fruit receptor 6 has a retaining end 3
1 is formed. This engaging end 31 engages with the engaging groove 30 of the casing 3' to fix the fruit receiver 6 to the casing 3'. Further, a first small-hole plate 5 supported by a fixing portion 32 on the inner periphery of the fruit receiver 6 is attached to the lower part of the inside of the fruit receiver 6. This first small hole plate 5
A large number of small holes 5' are formed therethrough. The small holes 5' of the first small hole plate 5 have, for example, a cylindrical or polygonal shape of about 3 to 10 nm, and the surface in contact with the epidermis of the fruit has a wide-angle cone shape or a polygonal pyramid shape. There is. It is used depending on the type of fruit and the purpose of squeezing, but in the case of apples, a small hole 5' with a wide upward angle and a diameter of about 511I11 is suitable.

Furthermore, a fruit juice outlet 8 is formed in the lower part of the fruit receiver 6 for extracting the squeezed fruit juice. In addition, 7 indicates the handle of the fruit receptor 6, 9 indicates the leg of the fruit receptor 6, and a indicates an apple.

Next, a method for extracting fruit juice using this fruit juice extracting device will be explained.

First, an apple a is placed into the fruit receptor 6 without being subjected to any pretreatment such as splitting. Then, the engaging end 31 of the fruit receiver 6 is engaged into the engaging groove 30 of the casing 3' to fix the fruit receiver 6 to the casing 3'.

Next, the stress linear conversion device 2 is operated to move the push plate 4 to the first position.
The apple a is crushed by the pressing plate 4 by moving it in the direction of the arrow in the figure.

FIG. 2 shows that after the fruit receiver 6 shown in FIG. 1 is attached to the casing 3' of the pressing device 3, the apple a
It shows the crushed state.

When apple a is pressed against the first small-hole plate 5, the epidermis is torn first;
The pulp enters the bell-shaped small hole 5' having a wide angle surface, is compressed, narrowed by the bell shape, and moves downward.

As a result, the epidermis remains on the first small hole plate 5, and the degassed pulp C that has been compressed and penetrated through the small hole 5' of the first small hole 15 hangs down. At that time, the fruit juice d is separated from the deaerated pulp C and squeezed out. Since this juice d is squeezed out in a short time, the fruit juice d does not undergo any discoloration or deterioration, and its nutrients are not impaired. The above-mentioned fruit juice d flows down from the fruit juice outlet 8 and enters the cup 1.
0 and used as squeezed fruit juice d'.

Note that the pulp that has been compressed and penetrated through the first small hole plate 5 still contains some fruit juice and is in a deaerated state, so this deaerated pulp C is separated from the small hole 5' of the first small hole plate 5. It can be taken out and used as a pulp-based food such as diam, or mixed with fruit juice d to produce a chewy pulp-containing juice.

After the fruit juice d has been squeezed out, the press plate 4 is pulled up to the state shown in FIG. The pulp C' is peeled off and processed.

According to this embodiment, the apple a can be put into the juice extracting device as it is without any pre-processing such as crushing or cooking, and then it can be crushed by the pressing plate 4, so it requires almost no effort and is very quick. The fruit juice d can be squeezed out in a short period of time (for example, about 20 to 50 seconds). In addition, the epidermis b, which was difficult with conventional techniques,
Fruit pulp and fruit juice d can be effectively separated and expressed. Therefore, deterioration and discoloration of the fruit juice d can be prevented without impairing the taste, nutrients, aroma, etc. of the fruit juice d. Furthermore, since the structure of the fruit juice extraction device is extremely simple, processing of the squeezed residue (de-juiced fruit pulp C) after juice extraction and cleaning of the device can be done easily.

Although the explanation in this first embodiment is based on an example of a fruit with a thin epidermis such as an apple a, the present invention is not limited to this and can be similarly applied to other fruits. It is. For example, citrus fruits such as mandarin oranges, pineapple, etc.
In the case of other fruits with thick skins, the juice of many types of fruits can be squeezed out in the same way by dividing the fruit as appropriate, directing the pulp toward the perforated plate and pressing the epidermis with a pressing plate.

In the description of the first embodiment, the fruit juice extraction device is described as being of a vertical type, but the device is not limited to this, and may be either a horizontal type or an oblique type. The perforated plate 5 may be moved and pressed.

(B) Regarding the second embodiment FIG. 3 shows a second embodiment.

The configuration of this second embodiment differs from the first embodiment as follows:
The second small hole W, 11 and the elastic member amount 2 are arranged between the first small hole plate 5 in the fruit receiver 6 and the fruit juice outlet 8.

A feature of the second small hole plate 11 is that a large number of small holes 11' are formed through the second small hole plate 11. This small hole 11" is the deaerated pulp C.
Since the fruit juice d must pass through without passing through, it is necessary to make the hole smaller than the small hole 5' of the temporary first small hole 5.

As in the first embodiment, circular or polygonal small holes of about 1 to 5 m are used depending on the purpose. In the case of apple A, if the small hole 5' of the first small hole plate 5 is a conical shape with an upward wide angle of about 5 mm, it is suitable that the small hole 11' of the second small hole plate 11 has a circular shape of about 3 mm. By combining this with the optimum pressing force, the juice extraction efficiency can be improved to around 70 to 80%.

The extensible member 12 is made of an elastic material such as rubber, and urges the second temporary small hole 11 toward the first small hole plate 5 side. Since this elastic member 12 only needs to be able to bias the second small hole plate 11 toward the first small hole plate 5 side by elasticity, a spring can also be used.

In FIG. 3, a second
A state in which the small hole plate 11 and the elastic member 12 are attached, the first small hole plate 5 is placed thereon, and the apple a is crushed in the same manner as in the first embodiment is shown.

In this case, the epidermis remains on the first small-hole plate 5, and the degassed pulp C that has been compressed and penetrated through the small holes 5' is squeezed out between it and the second small-hole plate 11. The second small-hole plate 11 is urged toward the first small-hole plate 5 by the stress of the rubber spring of the elastic member 12, so that the deaerated fruit pulp between the first small-hole plate 5 and the second small-hole plate 11 teeth,
The fruit is compressed and the juice d is squeezed out, resulting in dejuiced fruit pulp C'. The fruit juice d is squeezed out through the small hole 11' and taken out from the juice outlet 8 into the cup 10.

According to this example, the skin of apple a, the pulp c, c'
, the fruit juice d can be almost completely separated, and the fruit juice d is transferred to the second small hole plate 1.
It can be expressed more efficiently and in a shorter time than through the small hole 11' of No. 1. In addition, by combining various types of small hole plates such as the first small hole plate 5 and the second small hole plate 11, it is possible to express deaerated fruit pulp C5 fruit juice d, etc. for different purposes. By the way, the second
The small hole plate 11 and the telescopic member 12 may be formed as one piece from an elastic material.

The other contents are the same as those in the first embodiment, so the same parts are designated by the same reference numerals and redundant explanation will be omitted.

FIG. 4 shows a state in which the small-hole molded body 13 is attached to the lower part of the fruit receiver 6, and the apple a is crushed to about half by the pressing plate 4.

At the tip of each vertically long small cylinder 13'' that constitutes the small hole molded body 13,
The epidermis of apple a is torn and the pulp is crushed into each small cylinder 13' one after another. At this stage, a small amount of fruit juice d is separated, flows down from the juice outlet 8, and is taken out into the cup 10 as squeezed fruit juice d'.

FIG. 5 shows a state in which the apple a is almost completely crushed into the small-hole molded body 13, and then the entire small-hole molded body 13 is crushed by the press plate 4.

All the pulp enters into each small cylinder 13' of the small hole molding 13. The small hole molded body 13 is crushed and the fruit juice d is squeezed out from the fruit pulp, and the fruit pulp becomes dejuiced fruit pulp C'. After the fruit juice d is separated, it is squeezed out from the juice outlet 8 into the cup 10 to become squeezed fruit juice d'.

In this embodiment, the small-hole molded body 13 is attached to the lower part of the fruit receiver 6, and the pulp of apple a crushed into each small tube 13' is crushed together with the small-hole molded body 13. fruit juice d
is being squeezed out. As a result, the squeezed residue (de-juiced pulp c”
) can be used as a disposable product after each expression, and post-processing can be performed quite simply.

The cross-sectional shape and length size of the small tube 13' constituting the above-mentioned small hole molded body 13 can be arbitrarily selected.

The other contents are the same as those in the first and second embodiments, so the same parts are designated by the same reference numerals and redundant explanation will be omitted.
