DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing fruit and vegetable juice which is free from agriculture, contains no heavy metal components, etc., and is capable of easily producing fruit and vegetable juice by completely separating fibrous materials, and an optimum juicer therefor. .

[0002]

2. Description of the Related Art In recent years, demand for health foods has been increasing more and more. At home, vegetable juices and fruit juices (hereinafter referred to as "vegetable juices") are attracting attention as health drinks that can be easily produced.

Conventionally, when producing this kind of fruit juice, a commercially available juicer mixer equipped with a scramble cutter is used, and the cutter is rotated at a high speed to squeeze the fruit juice while finely cutting the fiber of vegetables and fruits. In general, the fiber was precipitated to recover only the supernatant fruit juice.

[0004]

Problems to be Solved by the Invention Vegetables and fruits contain a large amount of pesticides and heavy metal components. Pesticides attached to the surface by ordinary washing are removed, but many pesticides and fibers still remain in the fiber. Contains heavy metal components.

However, in a conventional juicer mixer,
It is difficult to completely separate the fruit juice from the fiber, and the fiber is mixed into the fruit juice, and there is a concern about the adverse effects of pesticides and heavy metal components. Therefore, it was very complicated to purchase pesticide-free vegetables and fruits.

[0006] Further, since the scramble cutter is rotated at a high speed, there is a problem that vitamins, especially vitamin C, contained in fruit and vegetable juice are decomposed.

[0007] In view of the above problems, the present invention provides a method for producing a vegetable juice which can completely separate fiber from vegetable juice and fruit juice and which is optimal for in-house production without decomposing vitamins, and an optimal method for the same. The task is to provide a juicer.

[0008]

Accordingly, a method for producing fruit juice according to the present invention comprises a plurality of squeezing blades extending in the axial direction and having a predetermined inclination angle mutually opposite to the axial direction. Using at least one pair of cylindrical rotary cutters, the aperture blades of both rotary cutters are meshed with each other, and the rotary cutter is rotated at a low speed so that the meshing position shifts from the rear end to the front end. The fruit juice raw material is supplied, and the vegetable juice raw material is fed to the tip side along the throttle blade by the shifting mesh of the squeezing blade and pressurized, and the fruit juice is squeezed while almost maintaining the fiber quality. I do.

The important function of the squeezing blade of the rotary cutter is to feed the fruit and vegetable raw material forward while pressurizing it. In order to exhibit such a function, the blades are inclined in directions opposite to each other with respect to the axial direction. It is important. However, if the inclination angle is too steep, the fruit and vegetable juice raw material is strongly fed and cut into small pieces, and its fiber is finely divided and mixed with the fruit and vegetable juice. It is preferable to set the angle between 10 ° and 30 °. However, an inclination angle exceeding 60 ° may be acceptable depending on the kind of the fruit and vegetable juice raw material.

[0010] The rotary cutter is provided with two cutters and engaged with each other, but it is also possible to adopt a type in which three cutters are provided and the other one is engaged with one at the center. In this case, the support structure of the cutter and the like are somewhat complicated, but the squeezing efficiency of the fruit and vegetable juice can be improved as compared with the case of two vines.

Further, according to the present invention, it is possible to provide a juicer which is most suitable for performing the above-mentioned method for producing fruit and vegetable juice. That is, in the juicer according to the present invention, a unit case is formed with an input port for inputting the fruit and vegetable juice raw material, and a pair of left and right cylindrical rotary cutters extends in a substantially horizontal direction below the input port so as to be rotatable. The rotary cutters are provided with a plurality of aperture blades extending in the axial direction and formed at a predetermined inclined angle with respect to each other in the axial direction. Is characterized in that a filter for separating fibrous materials mixed in fruit and vegetable juice is provided.

Although it is necessary to rotate the rotary cutters in synchronization, if the pair of cutters are driven together, it is difficult to synchronize them. Therefore, it is preferable that one is driven by a drive source and the other is driven and rotated. For example, in the case of the three cases described above, it is possible to adopt a form in which one at the center is driven and the other two are driven to rotate.

Specifically, this juicer is provided with a horizontally long unit case extending substantially horizontally and detachably attached to the front side surface of the housing of the drive unit, and a pair of left and right cylindrical rotary cutters is installed in the unit case in a substantially horizontal direction. The unit is extended and rotatably supported, and an inlet for the fruit and vegetable juice is placed on the rear upper surface of the unit case, located above the rear part of the rotary cutter, and the fiber mixed with vegetable juice is located below the rotary cutter. The rotary cutter is provided with a filter that separates and separates the fruit juice downward, while the rotary cutters are formed with a plurality of throttle blades extending in the axial direction and formed at a predetermined inclined angle to each other with respect to the axial direction. The rotary cutter is configured to be meshed with at least one of the rotary cutters detachably connected to a drive shaft of a drive device.

The pomace may be sent forward and discharged from the case, or a peg may be provided below to separate the pomace from the fruit juice. However, in the case of sending the slag forward, the slag discharge force is insufficient with only the feed force of the squeezing blade, and the slag may not be smoothly discharged. In such a case, a mechanism for smoothly pushing out the slag separated at the tip of the rotary cutter from the discharge hole at the tip of the unit case,
For example, if a feed screw rod in which reverse screws are meshed with each other is provided, it is possible to reliably discharge slag in a small layout space.

The discharge port of the residue is formed with an opening of a simple shape such as a circle or a square between the feed screw rod support portions of the case. However, when the residue moves from the feed screw rod to the discharge port, it falls off. May be affected. Therefore, it is preferable to form a receiving portion having a large opening area on the inner side of the slag discharge port and guide the slag sent by the feed screw rod to the discharge port. In addition, when the receiving portion is provided, a protruding portion is formed on both sides of the discharge port portion, so that the support portion of the feed screw rod,
For example, it is preferable that a bearing hole or the like can be formed more easily.

The thread of the feed screw rod may have a simple thread shape. However, when the squeezing residue is pressed and fed, there is a possibility that the thread is pushed out of the thread groove and spills. Therefore, when the feed side of the thread is formed to have a substantially vertical or reversely sloped cross-sectional shape, the slag can be fed while being pressed and held in the screw groove, and reliable feeding becomes possible.

Since it is important for the feed screw rod to feed the slag while pressing forward, it is important to engrave the helical screw on the reverse screw. Moreover, in order to secure the feeding force, it is preferable to set the inclination angle to a steep angle with respect to the axial direction, for example, 70 ° or more. However, when the angle approaches 90 °, the feeding speed becomes extremely slow. Therefore, in consideration of an appropriate feed force and feed speed, it is preferable to set the angle to about 75 ° to 85 °.
Needless to say, the angle may be 70 ° or less when the fiber quality of the fruit and vegetable juice raw material is soft and slightly delayed.

It is important to rotate the rotary cutter at a low speed. Therefore, it is preferable to use a motor with a speed reducer as a drive source of the rotary cutter.

When the rotary cutter is built into a unit case to form a unit and is mounted on the housing of the drive unit, the unit can be easily washed and removed after use, so that the drive unit can be applied to other uses. Good to do. Therefore, a connection seat is formed on the side of the housing at the tip of the mounting base protruding laterally so as to protrude in the outer edge direction,
At one end of the unit case, a connection seat that has the same shape as the housing connection seat and can be brought into surface contact with each other is formed so as to protrude in the outer edge direction, and a substantially inverted U-shaped cross section is substantially equal to the outer peripheral edge shape of the connection seat. It is continuous and divided into at least two parts to form a fastening fitting. The two connecting seats are superimposed on each other, the fastening fitting is removably fitted around the entire outer edge thereof, and the fastening plastic fittings are interconnected to connect the two connecting seats. It is good to tighten and fix.

[0020] Since both connecting seats of the housing and the unit case are tightened and fixed around the entire outer edge thereof by a tightening fitting, they are firmly connected to each other. Therefore, it is preferable to form a positioning projection on one of the two connection seats and a positioning recess on the other, into which the positioning projection can be fitted, and position them relative to each other before fitting the fastener. The shapes of the positioning projections and recesses are not particularly limited as long as they can be positioned.

Since the fastening fitting is fitted around the entire outer periphery of both connecting seats to fasten and fix the connecting seats, the inverted U-shaped cross section is continuous to a shape substantially equal to the outer peripheral shape of the connecting seat. Should be fine. For example, a structure in which the fastening fitting is divided into a plurality of fitting pieces, each of which is fitted to the outer edges of both connection seats overlapped with each other, and which are connected to each other with bolts and nuts or the like may be used, but the fitting and fastening operations are only complicated. And it is easy to lose fasteners. Therefore, the clamp is divided into two metal pieces, and one end of both metal pieces is connected to the connection seat of the housing or the case so as to be able to swing up and down, and the other end of both metal pieces is freely swingable with a tightening screw. The other end of the other bracket piece has a locking groove in which the tightening screw fits.
It is preferable that the metal fittings be fitted around the entire outer edges of both superposed connecting seats, and the tightening screws be swung to fit into the locking grooves and tightened.

The tightening screw is formed by screwing a knob portion to a screw rod so as to be able to advance and retreat, and a protruding piece portion is bent outward at the other end of one of the metal fittings so that one end of the screw rod is vertically swung. Pins are freely connected, and the other end of the other metal piece is bent outwardly with a protrusion overlapping with the one protrusion to form a locking groove therein, and the protrusion of one metal piece is formed. It is preferable to connect the metal pieces by sandwiching the protruding piece of the other metal piece between the screw and the knob of the tightening screw.

[0023]

[Operation and Effect of the Invention] The rotary cutter is driven,
When the fruit and vegetable raw material is supplied between the cutters, the fruit and vegetable raw material is gradually bitten by the meshing aperture blades. Since the meshing position of the aperture blade gradually shifts forward with the rotation of the rotary cutter due to the shape of the aperture blade, the vegetable juice raw material is bitten by the aperture blade and is sent forward along the aperture blade. Pressurized, the fruit juice is squeezed out and dripped downward while the fiber quality is almost maintained. The scum that maintains the fiber quality is sent to the tip of the rotor cutter.

Therefore, since the fiber quality is almost maintained and separated from the fruit and vegetable juice, the finely cut fiber does not mix into the fruit and vegetable juice, and the concern of pesticides and heavy metal components can be completely removed, and the pesticide-free Not limited to those, any vegetables and fruits can be used.

Further, the rotary cutter does not need to be rotated at a high speed unlike the conventional scramble cutter.
It is enough to rotate about three times, and the vitamins of the fruit juice are not decomposed.

On the other hand, as shown in FIG. 2, FIG. 6 to FIG. 8, a substantially square mounting base 11 is protruded forward substantially at the center of the front side surface of the housing 10, and the front end surface of the mounting base 11 is A step portion 12 having a small diameter is protruded, and a flat connection seat 13 is integrally formed on a distal end surface of the step portion 12.
Is set to have an outer shape slightly smaller than the outer shape of the mounting base portion 11, and a positioning ridge portion 14 is provided on the distal end surface of the connection seat 13 so as to project in a substantially square shape.

At the rear end of the unit case 20, a connecting seat 28 integrally formed with a small-diameter step 27 is fixed by mounting screws. The connecting seat 28 has the same shape as the connecting seat 13 on the housing 10 side. They can come into contact with each other. A step 29 into which the positioning ridge 14 can be fitted is recessed in the rear end surface of the connection seat 28.

The clamp 3 has a generally inverted U-shape in cross section and is continuous with the outer shape of the connection seats 13 and 28. The clamp 3 is divided into a pair of upper and lower metal pieces 30. Is mounted on the side surface of the mounting base 11 of the housing 10 by a mounting pin so as to be vertically swingable.

At the other end of each of the metal pieces 30, a protruding portion 32 is formed so as to project outward so as to overlap with each other, and a groove 320 is formed in the protruding portion 32 in the longitudinal direction. The screw rod 3 of the tightening screw 33 is in the groove 320 of the projecting piece 32.

The knob portion 331 is screwed into the groove (locking groove) 320 of the piece portion 32 and the upper projecting portion 32 is sandwiched between the knob portion 331 and the lower projecting portion 32. Metal piece 3
0 are mutually connected. The fitting piece 32 is formed with a relief at a raised portion for the mounting screw of the connection seat 28.

When the juicer unit 2 is mounted on the drive unit 1, first, as shown in FIG.
After the receiving case 21 is installed from below in the inside, the rotary cutters 24 and 25 are inserted from the rear end side of the receiving case 21, and the metal piece 30 of the fastening metal 3 is opened up and down.

Next, as shown in FIG. 6, the connection seat 28 of the unit case 20 is pressed against the connection seat 13 of the housing 1, and the positioning ridge 14 on the connection seat 13 side is connected to the connection seat 28.
Of the rotary cutters 24 and 25 and the rear end shafts of the rotary cutters 24 and 25.
It can be inserted into the bearing on the side to transmit the driving force.

In this state, the upper and lower metal pieces 30 are swung in the closing direction and fitted around the outer edges of the superposed connecting seats 13 and 28, so that the protruding pieces 32 overlap each other as shown in FIG. When the tightening screw 33 is swung upward to fit into the locking groove 320 of the upper protruding piece 32 and the knob 331 is turned and screwed as shown in FIG.
The upper projecting piece 32 is strongly clamped between the lower projecting piece 31 and the lower projecting piece 32, and the upper and lower metal pieces 30 are connected to each other, whereby the connecting seats 13 and 28 are connected to each other. The end side is attached to the attachment base 11 of the housing 10 in a cantilever state.

At this time, the fitting piece 30 of the fastening fitting 3 is fitted around the entire outer periphery of the connecting seats 13 and 28, and the connecting seat 1
3 and 28 are abutted on a relatively large surface, and the unit case 2
Since the weight on the 0 side is distributed and received over the entire contact surfaces of the connection seats 13 and 25, the receiving case 2
1 and rotary cutters 24 and 25 are built in, and even when the weight is relatively heavy, the connection seat 25 of the unit case 20 does not shift or come off from the connection seat 1 of the housing 10, and the unit case 20 can be accurately and reliably mounted. Can be mounted in a cantilevered state.

On the other hand, after squeezing the fruit juice, it is necessary to wash the juicer unit 2 with water. In this case, the reverse operation may be performed, and the juicer unit 2 can be removed very easily. And can be easily removed.

In the case of producing fruit juice, the control circuit is turned on to activate the driving device 1 to drive the rotary cutter 24, and the rotary cutter 25 is driven to rotate, as shown in FIG. A fruit and vegetable juice raw material, for example, a stem or leaf portion of a vegetable is charged from the charging port 203. Then, the aperture blades 240, 2 of the rotary cutters 24, 25
50 mesh with each other, and the meshing position gradually shifts forward with the rotation of the rotary cutters 24 and 25.
It is bitten by 50 and is pressurized while being fed forward by aperture blades 240 and 250. Thereby, the fruit and vegetable juice is squeezed and the receiving case 21
And falls downward from the filter 22.

At this time, the stems and leaves of the vegetables are cut by the engagement of the squeezing blades 240 and 250, and a part of the fiber may be mixed into the fruit and vegetable juice. Since the fruit juice that is separated and contains no fiber falls from the filter 22, the fruit juice that leaves a container or the like below the juicer unit 2 can be obtained.

After the fruit juice has been squeezed, the stems and leaves of the vegetables are fed from the squeezing blades 240 and 250 to the feed screw rods 241 and 251.
It is sent between and received by the feed screw rods 241 and 251.
Since the stem and leaves after the squeezing substantially maintain the fibrous property, and the feed screw rods 241 and 251 extend substantially horizontally and their helical reverse screws are meshed with each other, The meshing position of the threaded rods 241 and 251 can also be shifted from the rear end side to the distal end side by the rotation of the rotary cutters 24 and 25. It can be pressed and sent toward its tip.

When the slag reaches the tip of the feed screw rods 241 and 251, the slag is pushed into the discharge port 204 on the side of the unit case 20 by the feed force, and the discharge port 2.
04 is pushed out of the unit case 20.

The swarf is strongly pressurized while being fed by the feed screw rods 241 and 251, and may be finely divided and fall ragged from the feed screw rods 241 and 251. Since it is received in the case 21 and separated from the vegetable juice by the filter 22, it does not mix into the vegetable juice.

When the slag moves to the feed screw rods 241 and 251 discharge port 204, the slag may fall downward. However, since the receiving surface section 205 is formed on the near side of the discharge port 204, The dropped residue is received by the receiving surface portion 205 and pushed into the discharge port portion 204 together with the residue sent by the feed screw rods 241 and 251, and the unit case 2
It does not spill into zero.

Therefore, the residue can be reliably removed from the unit case 2.
It can be drained from 0, and the scum does not fit into the fruit juice.

When a raw material having a low fiber content, such as a fruit portion of a vegetable or a fruit, is used, the narrowing blade 24 is used as it is.
Since it does not bite into 0 and 250 well, it should be pushed from above with a holding rod or the like.

In the case of a raw material having a large amount of fibrous material, the throttle blades 240 and 250 may bite the raw material and stop. In such a case, the rotary cutters 24, 25
Is stopped once and then reversed, the strong biting of the raw material can be easily removed. Therefore, it is preferable to set such a function in the control circuit of the driving device 1.

In the production method of this example, the fiber quality is almost maintained and separated from the fruit and vegetable juice, so that the finely cut fiber does not mix into the fruit and vegetable juice, and concerns about pesticides and heavy metal components are completely eliminated. It can be removed and any vegetable or fruit can be used as a raw material.

The rotary cutters 24 and 25 are
It is sufficient to rotate about 3 times at low speed, and the vitamins of the fruit juice are not decomposed.

Therefore, it is possible to easily produce a fruit and vegetable juice containing sufficient vitamins, completely separating the fibrous material and free from worry about pesticides and heavy metal components.
