Description

A juicer for decreasing the amount of pulp in a juice is known as a pulp in the juice.

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to an apparatus and a method for changing a shape of a drum and a screw, in particular, to reduce the amount of pulp that can be contained in a juice.

A conventional vertical centrifugal separator includes a screw into which a juice object such as fruit or vegetable is introduced and cut, conveyed, crushed, or pressed. The screw is provided on the inner side of the drum, and the juice is divided into juice and pulp by the rotation of the screw in the process of passing the fruit juice between the mesh net and the drum, including the mesh net. The juice and pulp are separately collected at the bottom of the drum and are discharged separately through the respective outlets.

The conventional vertical centrifugal separator is divided into a type in which a mesh drum is adopted and a type in which a mesh net is integrally provided with a screw without adopting a network drum. An example of the former is Korean Open Publication No. 2012-0029638, and an example of the latter is Korean Open Publication No. 2012-0042606.

Of the types in which the mesh net is integrally provided with the screw, both the juice and the pulp are discharged downward in the drum and the pulp is discharged to the drum side by the rotation of the screw. In the latter case, it is possible to adjust the pulp amount by attaching an appropriate mechanism to the pulp discharge part, and it is possible to extract the juice again from the pulp. As an example of the former, Korean Laid-open Publication No. 2013-0042991 can be cited, and as an example of the latter, Korea Laid-open No. 2016-0014959.

1 to 4 includes a cover 100, a screw 200, a drum 300, and a main body 400. [

The lid 100 is provided with an injection port 130 through which the user can inject the juice object into the inner space of the drum 300. The cover 100 is provided at its lower side surface with a binding jaw 120 for connection with the drum 300.

The screw 200 is connected to a power member (not shown) such as a motor provided inside the main body 400 and is rotatable. The screw 200 works together with the drum 300 fixed so as not to rotate to juice the juice.

The screw shaft 200 is provided with a rotary shaft 210. The rotary shaft upper portion 211 is rotatably fixed to the rotary shaft fixing groove 110 at the lower portion of the lid 100. A square shaft hole 212 is located below the rotary shaft fixing hole 110 And is rotatably connected by a prismatic shaft 410 of the body 400.

A predetermined space is formed between the upper part of the screw 200 and the drum 300. When the juice is injected from the injection port 130,

As the screw 200 rotates, the screw rib 220 cuts, crushes and pressurizes the juice object put into the space by the screw rib 220, and separates the juice into pulp and juice .

A mesh network 270 is located below the screw 200. Of the juice and pulp flowing below the screw 200, the juice flows into the screw 200 through the mesh net 270 and the pulp does not pass through the mesh net 270, Lt; / RTI >

The drum 300 is detachably mounted on the main body 400, and the screw 200 is rotatably fixed to the inner space. A screw fixing portion 315 is provided at the center of the drum 300 in a hollow cylindrical shape and the rotary shaft 210 of the screw 200 is inserted and fixed through a hole located on the upper surface of the screw fixing portion 315 .

The juice is formed by the interaction of the screw 200 and the rib 320 of the wall surface of the drum 300. The rib 320 on the inner wall of the drum 300 may be divided into a first rib 321 and a second rib 322 according to the length thereof.

The bottom surface of the drum 300 is provided with a radially outer first guide groove 331 and a radially inner second guide groove 351 separated by the inflow preventing rib 339, The pulp flowing inward flows along the second guide groove 351 and the pulp flowing outside the screw 200 flows along the first guide groove 331.

The pulp flowing along the first guide groove 331 is discharged to the outside through the first discharge portion 340 after passing through the first discharge hole 332 provided on the side of the drum 300, The juice flowing along the guide groove 351 passes through the second discharge hole 352 and is discharged to the outside through the second discharge portion 360.

The first discharge portion 340 may be provided with a discharge resistance member 342 so that the amount of pulp can be adjusted. A discharge resistance member 342 is located outside the first discharge member 341 extending from the drum 300. Resistive and asymmetric resistance surfaces 342b and resistance member insertion protrusions 342a are located in the discharge resistance member 342 and inserted into resistance member insertion holes 343a located at the center of the discharge adjustment portion 343, The user can rotate the discharging resistance member 342 by rotating the outermost discharge adjusting portion 343. And a connection portion 344 for connecting these components is further provided.

The second discharge portion 360 includes a second discharge member 361 extending from the drum 300 and a cover 362 provided on the outer side. The lid 362 can be attached and detached by the engagement groove 365 at the end of the second discharge member 361.

The main body 400 supports the drum 300 and is connected to an external power source.

A power member (not shown) such as a motor is mounted on the inside of the main body 400 and provides a rotational force to the screw 200 through the angular shaft 410 when power is supplied from an external power source. Around the square shaft 410, a plurality of fixing protrusions 440 for fixing the drum 300 are inserted into the lower surface of the drum 300.

The drum 300 is fixed to one side of the main body 400 with a drum supporting member 430 extending upward and capable of contacting one side of the drum 300. The fixing drum 300 supports the drum supporting surface 432 . The degree of fixing can be adjusted by the drum supporting member 431. [

When a user wishes to use such a conventional control device, a fruit juice such as fruit or vegetables is put through the injection port 130, and when the power is applied to the juicer, the juice is separated into pulp and juice, (340) and the second discharge unit (360). The user drinks only the juice, which is the juice discharged through the second discharge portion 360, and discards the pulp. That is, since the pulp is generally discarded, it is preferable that the pulp amount in the juice discharged through the second discharge portion 360 is small.

However, in the case of using a conventional squeezer to squeeze leafy fibers having a large amount of fiber such as celery, the fibers constitute pulp having a long length and are not easily discharged through the first discharge portion 340, When the unfit pulp is piled up in the first guide groove 331, a phenomenon occurs that the ink flows into the second guide groove 351 over the inflow preventing rib 339 in the bottom surface of the drum 300.

Since the pulp introduced into the second guide groove 351 is discharged through the second discharge portion 360 together with the juice, the amount of pulp in the juice increases, and when the juice is consumed by the user, Lt; / RTI >

Although the present invention has been described by taking the master secretary as an example, the same principle may be applied to devices other than master secretary. For example, the scope of the present invention is also applicable to a mixer, a green pot, and the like.

The constituent elements of the present invention can be used integrally or individually as needed. In addition, some components may be omitted depending on the usage form.

Preferred embodiments of the present invention will be described with reference to the accompanying drawings. In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, the definitions of these terms should be described based on the contents throughout this specification.

Further, in the following, "fruit juice" is an object juiced by juice juice. For example, fruits and vegetables may be included, but it is natural that there is no restriction on the kind.

Hereinafter, the term "juice" means a process in which a juice object is subjected to a complex action such as cutting, transferring, squeezing, and pulverizing.

Hereinafter, "juice" is a kind of liquid that is juiced and discharged to a predetermined level to allow juice to pass through the mesh net, and "pulp" is not discharged enough to pass through the mesh net, It means a kind of solid. Of course, it is not completely separated into a liquid and a solid, and as a result, it is possible to distinguish juice and pulp depending on whether or not they pass through a mesh network. That is, the ratio of the juice to the pulp may be changed by changing the size of the pores constituting the mesh network.

The "pulp" may be a residue, or it may be included in the juice to improve texture during drinking. For example, in the case of orange juice, the orange juice may become a juice, and the granules and the like may become pulp. If the user does not drink pulp (i.e., orange grains) with orange juice, However, if they are to be drunk together, pulp (that is, orange pellets, etc.) is discharged together with the juice to be consumed by the user.

Hereinafter, the present invention will be described in more detail with reference to the drawings. Here, the function and structure of the lid 100 and the main body 400 are similar to those of the conventional loudspeaker, and a description thereof will be omitted.

1. Causes of pulp in juice

The principle of the introduction of the pulp into the juice was first analyzed in a master batcher of the same type as that of the present invention, that is, a master batch in which the mesh net is integrally provided in the screw and the pulp is discharged to the side of the drum.

When the juice object is put in and the screw 200 is rotated, the juice object is separated into juice and pulp. The separated pulp descends along the outer surface of the screw 200 and collects in the first guide groove 331. The pulp gathered here rotates together with the rotation of the screw 200 and rotates together with the first discharge hole 332 And must be discharged through the first discharge portion 340 (see FIG. 4).

However, when the fruit juice containing a lot of long fiber is juiced, the pulp having a long length is separated from the first discharge hole 332, and the pulp does not easily escape from the first discharge hole 332 and continues to the first guide groove 331 . Particularly, the first discharge hole 332 is provided on the side surface rather than the lower surface of the drum 300.

Meanwhile, the screw 200 is inserted into the first guide groove 331 and rotated (see FIG. 10A). That is, the mesh network holder 280 at the lowermost end of the screw 200 is rotated in a state where it is inserted into the first guide groove 331.

However, as the pulp is accumulated in the first guide groove 331, the screw 200 naturally rises simultaneously with the rotation. The distance between the inner wall surface of the drum 300 and the screw 200 is shortened when the screw 200 rises and the compressive force is increased and the juicing rate is increased. 10A, the lower surface of the screw 200 contacts the first guide groove 331 while the screw 200 is not rotated (hereinafter referred to as a first state) During the rotation (hereinafter, referred to as a second state), the pulp flows upward into the first guide groove 331 as shown in FIG. 10B. Therefore, as shown in FIG. 3, a clearance d ₀ is generally spaced between the rotation shaft upper portion 211 of the screw 200 and the rotation shaft fixing groove 110 of the lower portion of the lid 100.

As the pulp is excessively accumulated in the first guide groove 331, the screw 200 is excessively lifted. In this case, the space between the first guide groove 331 and the screw 200 is widened, A phenomenon of radially inward overflow occurs (see Fig. 10B). That is, the pulp accumulated in the first guide groove 331 overflows the second guide groove 351 beyond the inflow preventing rib 339. Since the second guide groove 351 has a separate juice, the pulp flows into the juice in this process.

In order to prevent this, it is possible to consider a method of shortening the clearance distance d ₀ between the upper part of the rotating shaft 211 and the rotating shaft fixing groove 110 of the lower part of the lid 100. However, when the pulp becomes excessively large As a result, there is no clearance space for the screw 200 to rise, so that other problems may occur, such as imposing strain on the other components in the master cylinder and reducing durability.

Alternatively, the inflow preventing rib 339 may be configured to be high to prevent the pulp accumulated in the first guide groove 331 from passing over the inflow preventing rib 339. In this case, The juice through the mesh net 270 may be blocked to reduce the juicing rate.

Thus, in the present invention, the shape of the mesh net holder 280 of the screw 200, the height of the inflow preventing rib 339, and the height of the inflow preventing ribs 339 are set so as to reduce the amount of pulp in the juice, 1, the shape of the discharge hole 332 and the first guide groove 331 is modified from that of the prior art.

2. The shape of the mesh net holder 280 of the screw 200 and the height of the inflow preventing rib 339

First, a screw 200 according to the present invention will be described with reference to FIG. 5 and FIGS. 10A and 10B. 5, the illustration of the mesh network 270 is omitted for the sake of explanation.

The mesh net holder 280 functions to support the mesh net 270 from the screw 200 and is a member located at the lowermost end of the screw 200.

In the present invention, it is preferable that the upper surface of the mesh net holder 280 is inclined to be lower toward the radial center. This is to naturally guide the juice flowing through the mesh net 270 toward the radial center toward the second guide groove 351.

At the same time, the uppermost surface of the inflow preventing rib 339 touches the extension line (the dashed line in Fig. 10B) of the upper surface of the mesh net holder 280 on the basis of the second state in which the screw 200 is raised to the highest height The height of the inflow preventing rib 339 is determined.

The height of the inflow preventing rib 339 must be as high as possible in order to prevent the pulp accumulated in the first guide groove 331 from flowing into the second guide groove 351 beyond the inflow preventing rib 339. However, If the height of the first guide groove 339 is higher than the above-mentioned extension line, the juice is prevented from flowing into the second guide groove 351.

That is, the optimum height of the inflow preventing rib 339 for maintaining the juicing rate and preventing the inflow of the pulp into the juice is larger than the optimum height of the inflow preventing rib 339, (The dashed line in Fig. 10B).

The height of the mesh hole 271 at the lowermost end of the mesh net 270 is also important to prevent pulp from mixing with the juice, and will be described with reference to FIGS. 10A and 10B.

As described above, after determining the height of the inflow preventing rib 339, the height of the lowermost mesh hole 271 of the mesh net 270 is determined.

In the first state, the uppermost surface of the inflow preventing rib 339 is higher than the lowermost mesh hole 271 of the mesh net 270. In other words, the value of the distance d _{L obtained} by subtracting the height of the mesh hole 271 at the lowermost end of the mesh net 270 from the height of the inflow preventing rib 339 is a positive number.

In the second state, the uppermost surface of the inflow preventing rib 339 is lower than the lowermost mesh hole 271 of the mesh net 270. In other words, the value of the distance d _{U obtained} by subtracting the height of the lowermost mesh hole 271 of the mesh net 270 from the height of the inflow preventing rib 339 is negative.

Here, the difference between the distance d _L and the distance d _U is the maximum height d _{1 at} which the screw 200 ascends. This is because the upper portion 211 of the screw shaft 200 and the cover 100, Is smaller than the distance d ₀ (see FIG. 3) between the lower rotary shaft fixing grooves 110.

3. The shape of the first discharge hole 332 and the shape of the first guide groove 331

Even if a large amount of pulp such as fibrous material having a long length is accumulated in the first guide groove 331, it is possible to prevent the pulleys accumulated in the first guide groove 331 from being overflowed by the second guide groove 351, It is important that the air is discharged to the outside through the air discharge hole 332.

Accordingly, in the present invention, in order to facilitate discharge of the pulp, the first discharge hole 332 in the prior art has only a rectangular shape (see FIG. 3) (332).

The upper portion of the first discharge hole 332 of the master cylinder according to the present invention is formed to have a rectangular shape similar to that of the prior art, but is wider than the lower portion of the first discharge hole 332.

In this case, when the upper portion of the first discharge hole 332 is also wide, not only the pulp accumulated in the first guide groove 331 is discharged, but the pulp is lowered along the screw 200 before being accumulated in the first guide groove 331 The pulp may be discharged. When the pulp descending along the screw 200 is pulled out through the wide upper portion before being accumulated in the first guide groove 331, the situation in which the juice to be lowered is pressed from below is released in the middle, The rate decreases.

The width of the lower portion of the first discharge hole 332 (the right side in FIG. 8) is larger than the width of the farthest portion (the right side in FIG. 8) (The left side in Fig. 8). This is because pulp discharged through the root portion is large in consideration of the rotating direction of the screw 200.

7, 8, and 9) of the screw 200, the lower portion of the first discharge hole 332 preferably has a smaller width. It may be configured as a triangle as shown in FIG. This is to prevent the pulp discharged to the first discharge member 341 through the root portion from being pulled back into the first guide groove 331 considering the rotating direction of the screw 200.

The shape of the first guide groove 331 should also be adapted to pulp discharge.

The radial inner wall of the first guide groove 331 has a circular shape and a semicircular shape in cross section. The inner wall of the first guide groove 331 is an inflow preventing rib 339, and the radially outer wall is a bottom wall of the drum 300, It is the corner part where the face meets. In particular, the corner portion forms a rounded wall body so as to form a semicircular cross section.

In the present invention, as shown in Fig. 9, at the portion where the rounded wall body of the first guide groove 331 meets the first discharge hole 332, by removing the rounded wall body, the pulp becomes more naturally discharged And then discharged through the hole 332.

Further, a separate cutting portion is located at the portion where the rounded wall is removed.

Specifically, the first cutting portion 333 is located on the circular portion (the right side in FIG. 9) from which the rounded wall body has been removed, based on the rotating direction of the screw 200 (arrows in FIGS. 7, 8 and 9). The second cutting portion 334 is located at the root (left side in Fig. 9) where the round wall is removed.

It is preferable that the first cutting portion 333 and the second cutting portion 334 are roundly cut in a C-cut shape for the natural inflow of the pulp.

In this case, the pulp rotates counterclockwise along the first guide groove 331, passes through the second cutting portion 334, and comes into contact with the portion where the rounded wall is removed. The pulp flows along the second cutting portion 334 The wall is naturally introduced into the portion where the wall is removed and discharged through the first discharge hole 332. In addition, the pulp that has flowed into the removed part of the wall but has not been completely discharged to the first discharge hole 332 rotates in the counterclockwise direction due to the rotational force, and can reach the first cutting part 333. 333 are prevented from flowing into the first guide groove 331 as much as possible.

Here, in order to more effectively prevent the pulp introduced into the wall-removed portion from being reintroduced into the first guide groove 331, one side of the first cutting portion 333 is bent at a predetermined angle It is preferable to bend further inward as much as the width (A). That is, one side of the first cutting portion 333 is preferably bent further inwardly by a predetermined angle A as compared with an extension line extending toward the radial center of the first guide groove 331.

3. Verification experiment

In order to confirm the difference in performance between the conventional cascade and the cascade adopting the structure according to the present invention, celery was squeezed. The total amount of celery as a fruit juice object was 500 g, and the sample was divided into Sample 1 and Sample 2 twice.

The amount of the juice discharged through the second discharge portion 360 after the juice was applied was checked, and the total juice ratio was calculated in comparison with the amount of the juice object. In addition, the amount of pulp removed from the juice discharged through the second discharge unit 360 was confirmed, and the juice rate was calculated by comparing the amount of the juice with the amount of juice. The pulp rate in the juice was also calculated through the amount of pulp removed relative to the amount of juice.

Fig. 11A is a result of an experiment in a conventional system. As a result, the total juice rates were 69.6% and 71.7%, respectively, and the pure juice rates were 66.7% and 66.8%, respectively. The juice pulp rate was 4.1% and 6.9%, respectively.

FIG. 11B is a result of the experiment in the master station according to the present invention. The total juice rate was 66.3% and 66.4%, respectively, and the pure juice rate was 63.9% and 65.0%, respectively. The juice pulp rate was 3.6% and 2.2%, respectively.

From these experimental results, it was confirmed that the pulp ratio in the juice was decreased by 0.5% and 4.7% in the sample 1 and the sample 2, respectively. In other words, it was confirmed that the amount of pulp in juice decreased considerably through this experiment. At the same time, the juice rate did not decrease much.
