Description

  The present invention relates to a fruit seeding device that separates fruits such as ginkgo, cherries, plums, and plums into pulp and seeds.

  Fruit, for example, plum pickled, is composed of hard seeds and soft pulp that covers the outside of the seeds. Umeboshi used for onigiri, etc., uses only the pulp after extracting the seeds, but if it is a small amount of umeboshi, there is no particular problem even if it is manually seeded. However, when a large amount of plum dried pulp is required for commercial use, a large amount of dried plum must be removed. However, when this work is performed by hand, it is time consuming and uneconomical and heavy labor.

Therefore, conventionally, the fruit to be treated, that is, the fruit from which the pulp and seeds are separated is mechanically processed using the following apparatus.
(1) Seed and pulp separation device that separates fruit from seeds that have fallen below the large drum and small-diameter roller so as to contact the front surface of the drum and separate the pulp from the seed (for example, Patent Document 1) ,reference).

  (2) A fruit seed remover comprising an extruding cutter that pushes a part of a seed by vertical movement and sandwiches the fruit between holding parts on a rotating plate that rotates intermittently (see Patent Document 2, for example) .

JP 2005-278561 A JP-A-8-80181

The conventional example has the following problems.
In Patent Document 1, seeds are collected without damaging them, but the pulp is scraped and broken apart. Therefore, this pulp is not suitable for use as a rice ball. Moreover, in patent document 2, since it takes a manual work in the setting in the fruit holding part, work efficiency is not good.

  In view of the above circumstances, an object of the present invention is to enable separation of seeds and pulp of a fruit to be treated in large quantities, continuously, efficiently and completely.

  The present invention comprises a large-diameter roller, a small-diameter roller facing the large-diameter roller via a pull-in gap and rotating in the same direction as the large-diameter roller, and a fruit charging guide provided above the pull-in gap A fruit seed removal device, wherein the width of the pull-in gap is smaller than the seed of the pulp to be treated, and a connecting straight line connecting the central axes of the two rollers is connected to the central axis of the large-diameter roller. And the top of the small-diameter roller is positioned below the horizontal line.

  An inclination angle of the connecting straight line with respect to the horizontal line of the present invention is 10 degrees to 20 degrees. The rotation speed of the large diameter roller of the present invention is faster than the rotation speed of the small diameter roller. The width of the pull-in gap according to the present invention is characterized by being 1-2 mm smaller than the diameter of the seed. The large-diameter roller and the small-diameter roller of the present invention are each driven by separate and independent driving means.

  The two rollers according to the present invention are characterized by comprising position adjusting means for adjusting the pull-in gap. The outer peripheral surfaces of the two rollers according to the present invention are subjected to uneven knurling. The guide according to the present invention is characterized in that the fruit to be treated is guided toward the large-diameter roller, and a perpendicular passing through the center of gravity of the fruit passes through a central portion of the pull-in gap. A pulp tray is provided below the pull-in gap according to the present invention.

  Since the present invention is configured as described above, the fruit to be treated falls into the drawing gap while being guided by the fruit charging guide, and is then drawn into the gap by the rotation of the large-diameter roller, and the pulp is deformed while being deformed. Fall through. The seeds of the fruit cannot enter the gap, are flipped to the top of the small-diameter roller, and discharged to the outside by the rotation of the small-diameter roller. Therefore, a large amount of fruit to be processed can be efficiently processed mechanically and continuously.

An embodiment of the present invention will be described with reference to FIGS.
The metal frame support 1 is provided with a large-diameter roller 3 and a small-diameter roller 5 having a diameter smaller than that of the large-diameter roller 3. Is facing through. The diameter of the large-diameter roller 3 is, for example, about twice the diameter of the small-diameter roller path 5, and the size of these diameters is appropriately selected as necessary.

  The central shaft 3 c of the large diameter roller 3 is provided in parallel with the central shaft 5 c of the small diameter roller 5. The connecting straight line L connecting the center axes 3c and 5c is inclined at an inclination angle θ, for example, θ = 10 degrees to 20 degrees with respect to a horizontal line F passing through the center axis 3c of the large diameter roller 3, and the small diameter roller 5 The top 5a is located below the horizontal line F. Therefore, the pull-in gap t is located below the horizontal line F.

  The width Y of the pull-in gap t is smaller than the size of the seed 7b of the fruit 7 to be treated, that is, the fruit from which the fruit 7a and the seed 7b are separated, for example, 1 mm to 2 mm smaller than the diameter of the seed 7b. Has been. The width Y of the gap t is adjusted by position adjusting means provided on the large diameter roller 3 and the small diameter roller 5, respectively. This position adjusting means includes horizontally movable bearing bases 8A and 9A and adjusting screws 8B and 9B for finely adjusting the vertical movement.

Concave and convex knurls R are applied to the outer surfaces of the rolls 3 and 5. Both rollers 3 and 5 are driven by drive motors 13 and 15 provided independently. The rotation directions of the rollers 3 and 5 are set to be the same, but the rotation speed of the large diameter roller 3 is set to be higher than that of the small diameter roller 5. For example, the rotational speed ratio between the outer surfaces of the large-diameter roller 3 and the small-diameter roller 5 is appropriately selected within a range of 1 to 5-10.
Note that the processing ability can be changed by changing the surface speed ratio by changing the position of the center of gravity of the fruit to be processed at the inclination angle θ.

  A fruit charging guide 17 is provided above the small-diameter roller 5. As this guide 17, for example, an inclined plate in which the fruit to be processed is wound on the large-diameter roller 5 side is used. The lower end portion 17a of the inclined plate 17 is located in the vicinity of the side surface of the large-diameter roller 3 and faces the top portion 5a of the small-diameter roller 5 via the space portion S, so that seeds separated from the space portion S can be discharged. It is like.

  In the figure, 20 is a belt conveyor that conveys the fruit to be processed to the apparatus, 21 is a pulp tray provided below the pulling gap t, 22 is a seed tray, 23 and 24 are chains, and 25 and 26 are roller rotation speed changes. Handles 27 and 28 are roller gears, respectively.

Next, the operation of the present embodiment will be described.
The rotation speed ratio is set independently for the large diameter roller 3 and the small diameter roller 5 rotating in the same direction A (clockwise direction), the large diameter roller 3 is set to the high speed side, and the small diameter roller 5 is set to the low speed side. In addition, the pulling gap t between the large diameter roller 3 and the small diameter roller 5 is set to be 1 to 2 mm smaller than the diameter of the seed 7a of the fruit to be treated, for example, plum dried 7, and the inclination angle θ is, for example, 10 degrees. Set to be.

  When the umeboshi 7 conveyed by the belt conveyor 20 falls above the rollers 3 and 5, the umeboshi 7 collides with the fruit charging guide 17, is caught in the large-diameter roller 3, and falls into the gap t. . At this time, the guide 17 is adjusted so that the position of the center of gravity of the umeboshi 7 corresponds to the center of the width Y of the gap t, so that the umeboshi 7 surely falls into the gap t.

  The dried ume 7 is pulled into the pulling gap t by the rotation of the large-diameter roller 3, but the seed 7b is larger than the width of the gap t, so it cannot enter the gap t, and only the pulp 7a. It passes through the gap t while being deformed. Therefore, the seed 7b is ejected from the fruit 7 and rides on the top 5a of the small-diameter roller 7a rotating in the clockwise direction, so that the pulp 7a and the seed 7b are completely separated. At this time, since the small-diameter roller 5 is located below the horizontal line F, the seed 7b is easily ejected.

  At this time, if the position of the center of gravity of the umeboshi 7 is set so that the tangents of the outer peripheral surfaces of the large-diameter roller 3 and the small-diameter roller 5 are vertical, the pulp 7a of the umeboshi 7 is reliably caught in the large-diameter roller 5. Then, it passes through the pull-in gap t and falls into the pulp tray 21. The seed 7b separated from the pulp 7a rides on the small-diameter roller 5 rotating in the clockwise direction, and is discharged into the seed tray 22 through the space S.

  The embodiment of the present invention is not limited to the above. For example, the present apparatus can be used to separate a soft object containing a hard object in addition to a fruit such as dried plums into a hard object and a soft object. Can be used. Accordingly, the processed fruit includes such an object.

It is a front view which shows embodiment of this invention. It is a side view of the said form. It is a top view of the said form. It is an enlarged plan view of a large diameter roller and a small diameter roller. It is an enlarged front view which shows the separation process of a to-be-processed fruit.
