<First Embodiment>
In FIG. 1, reference numeral 1 denotes the entire skin removing device of the present invention. The thin skin removing device 1 causes the coffee grounds supplied from the supply unit 11 to vibrate while moving in the traveling direction (right direction on the paper surface), removes the thin skin of the coffee beans on the main body unit 4, and discharges it from the discharge unit 12. . The main body portion 4 is fixed on the base 2 via the relay portion 3. Although there is no restriction | limiting in the magnitude | size of the main-body part 4, For example, it is about 30-50 cm in the advancing direction, and about 15-30 cm in the back | inner side.

  The base 2 preferably has a weight that stabilizes the main body 4, and is preferably formed of a metal such as stainless steel. The base 2 preferably has an elastic material such as rubber or cork on the back surface so that vibration from the main body 4 is not transmitted to the floor surface.

  A vibration part 7 is provided on the base 2, and vibrations generated by the vibration part 7 are transmitted to the main body part 4 via the relay part 3. There is no restriction | limiting in the structure of the vibration part 7, It is possible to produce | generate a vibration by various systems, such as a motor and an ultrasonic wave.

  The relay unit 3 stably connects the base 2 and the main body unit 4 and plays a role of imparting directivity to the vibration generated by the vibration unit 7. Specifically, the relay unit 3 includes substantially horizontal fixing units 3a and 3b that fix the base 2 and the main body unit 4, and inclined relay units 3c and 3d that are connected to the fixing units 3a and 3b at an angle. And has a parallelogram shape as a whole. Although not shown, the relay part 3 connects the base 2 and the main body part 4 by two sets of fixing parts 3a and 3b and inclined relay parts 3c and 3d. Of course, these two sets may be connected to each other, and the relay unit 3 may have a width in the depth direction (back side).

  As shown in FIGS. 2 and 3, the main body 4 has a rectangular shape that is long in the traveling direction, and its bottom surface is installed substantially parallel to the horizontal direction. The main body part 4 is provided with outer walls (separating part 15 and outer wall 4a) on the outer edges of two sides parallel to the traveling direction so that the coffee ground powder supplied does not fall.

  A plate-like supply part 11 provided to be inclined downward toward the main body part 4 is connected to the outer edge of the main body part 4 in the supply direction opposite to the traveling direction. Further, the outer edge of the main body portion 4 in the traveling direction is provided with a discharge portion 12 that is inclined downward from the main body portion 4 toward the traveling direction.

  The ends of the supply unit 11 and the discharge unit 12 are preferably provided with protruding portions in order to prevent the coffee grounds CF from spilling out. The supply unit 11 and the discharge unit 12 are formed, for example, by bending a single plate-like member. Moreover, you may make it have a tapering or divergent shape toward the advancing direction.

  And the coffee grounds CF supplied from the supply part 11 receives a vibration on the main-body part 4, advances to the advancing direction, and is discharged | emitted from the discharge part 12. FIG. Below the discharge part 12, a movable ground receiving part 13 is installed, and the ground coffee CF applied to the thin skin removing device 1 is collected.

  Here, the main body portion 4 is provided with a separation portion 15 adjacent to the main body portion 4. The separation part 15 is provided in parallel to the traveling direction, and serves as an outer wall of the main body part 4 between the main body part 4 and the separation part 15 and separates the main body part 4 and the separation part 15. A blower wall 14 is formed.

  The blower wall 14 has a two-layer structure having a cavity inside, and a plurality of blower holes (not shown) are provided on the wall on the main body 4 side. There are no restrictions on the position, size, number, interval, etc. of the air blowing, but for example, in the air blowing wall 14, the air blowing wall 14 is almost 0.5 to the position 1-10 mm from the bottom along the traveling direction. Holes with a diameter of about 0.2-2 mm are provided as blowing holes at intervals of -3 cm. There is no restriction | limiting in the shape and magnitude | size as a ventilation hole, For example, a slit-shaped hole may be sufficient. Moreover, in order to give directivity to a wind direction, it is also possible to provide the food | hood part which protrudes from the ventilation wall 14. FIG. Moreover, you may provide only in a part of ventilation wall 14, or may provide intermittently. Further, by devising the shape of the air blowing hole, etc., slightly downward (from the horizontal direction to 1-10 °, preferably about 3-7 ° downward) from a relatively high position of about 10-30 mm from the bottom. You may make it produce the flow of the wind which collides with the wind deflection | deviation part 5 and goes up by ventilating toward.

  The air blowing wall 14 is connected to the air blowing unit 6. The air blowing unit 6 generates wind by, for example, a fan and supplies it to the inside of the air blowing wall 14. As a result, wind blows out from the blower hole on the main body part 4 side in the direction crossing the traveling direction (that is, the back side).

  A plate-like wind deflecting portion 5 is provided on the outer wall 4 a opposite to the blower wall 14 in the main body portion 4. As shown in FIG. 2, the wind deflector 5 extends upward so as to extend the outer wall 4 a and then bends toward the blower wall 14. As a result, the blown air blown out from the blow hole is deflected along the wind deflecting portion 5 and travels toward the blow wall 14. In FIG. 2, for convenience, some members such as the supply unit 11 are omitted.

  The ground coffee CF includes light removal objects such as thin skin and dust. The blown air blows up the removal target and guides it to the separation unit 15, whereby only the removal target can be separated.

  That is, by the vibration generated by the vibration unit 7, the coffee grounds CF advances in the traveling direction while vibrating in the vertical direction. At this time, the ground coffee CF is agitated, and a lightweight removal target is lifted up. At this time, the blown air blows up a lightweight object to be removed.

  Further, the blown air is deflected along the wind deflecting unit 5 and the removal target is guided to the separating unit 15. At this time, a part of the ground coffee CF is also blown up by the blown air. However, since the ground coffee CF has a relatively large weight, the main body portion is deflected by the wind deflecting unit 5 and guided to the separating unit 15. 4 and mixed with ground coffee CF that was not blown up.

  Further, a part of the removal target blown up falls to the main body part 4 until it is deflected by the wind deflecting part 5 and guided to the separating part 15, but it is separated while being blown up many times while traveling. It will be guided to the part 15.

  As described above, the thin skin removing device 1 causes the coffee grounds to advance in the traveling direction by the directional vibration, and causes the coffee grounds on the main body portion 4 to float by the vibration. At this time, the thin skin removing apparatus 1 winds up the removal target including the light thin skin from the coffee grounds by the blowing air blown across the traveling direction, and guides it to the separation unit 15. At this time, the thin-skin removal apparatus 1 dares to blow out the blown air in the opposite direction to the separation unit 15, deflects the blown air by the wind deflecting unit 5, and crosses the traveling direction again, thereby separating only the removal target. In order to return to the main body 4 those that are not to be removed.

  Thereby, the thin skin removal apparatus 1 can selectively isolate | separate only the removal object, and can improve the quality of coffee grounds.

<Second Embodiment>
The second embodiment shown in FIGS. 4 and 5 is different from the first embodiment shown in FIGS. 1 to 3 in that the wind deflector is not provided. Note that, in the second embodiment, a reference numeral with 100 added is added to the corresponding part, and the same reference numeral is attached to the same part, and the description is omitted.

  As shown in FIG. 4, in the thin skin removing apparatus 101, the outer wall on the near side of the main body 104 also serves as the blower wall 114. A separation portion 115 is provided on the back side of the main body portion 104 so as to be adjacent to the main body portion 104, and a separation wall 104 a constituting an outer wall of the main body portion 104 separates the main body portion 104 and the separation portion 115. Yes. The separation wall 104 a is formed lower than the outer wall 115 a that constitutes the outer edge of the separation portion 115. In FIG. 4, for convenience, some members such as the supply unit 111 are omitted.

  Accordingly, the thin skin removing apparatus 101 blows out the blown air from the air blowing hole (not shown) provided in the air blowing wall 114 in the direction (back side) crossing the coffee ground CF and winds the object to be removed. The removal target is guided to the separation unit 115 installed adjacently.

  As shown in FIG. 5, the thin skin removing apparatus 101 is advanced by the vibration unit 107 directly vibrating the main body unit 104 and the main body unit 104 being inclined downward in the moving direction. A vibration having directivity in the direction is generated.

  The relay unit 103 only needs to have a function of connecting the base 2 and the main body unit 104, and the configuration thereof is not limited. Further, the relay unit 103 may have a function of absorbing vibration generated in the main body unit 104 and preventing the vibration from being transmitted to the base 2. For example, vibration can be absorbed by using a joint part or an elastic member for the relay unit 103.

  Further, a funnel-shaped member can be used as the supply unit 111. The supply part 111 can adjust the amount of ground coffee CF supplied from the supply part 111 to the main body part 104, for example, by having an open valve whose open area can be adjusted in the cylindrical part.

<Third Embodiment>
The third embodiment shown in FIG. 6 is different from the first embodiment shown in FIGS. 1 to 3 in that a separation guiding unit 220 is provided. Note that, in the second embodiment, a reference numeral with 100 added is added to the corresponding part, and the same reference numeral is attached to the same part, and the description is omitted. In FIG. 6, for convenience, some members such as the supply unit 11 are omitted.

  As shown in FIG. 6, the thin skin removing apparatus 101 has a separation guiding portion 220 that extends upward from the blower wall 14. The leading end of the separation guiding part 220 is inclined toward the back side. In addition, the separation unit 215 has, for example, a box shape, is separated from the main body unit 4, and is placed on the outside of the base 2.

  The thin skin removing device 101 winds up the object to be removed from the ground coffee CF by the blown air blown from the blower holes of the blower wall 14, and deflects the blown wind toward the blower wall 14 by the wind deflecting unit 5. The separation guide unit 220 is bent so as to follow the flow of the blown air, and guides the object to be removed riding on the blown air to the separation unit 215, while the relatively heavy weight that does not cover the blown air is a main body. It can be returned to part 4.

  According to the above configuration, it is possible to realize a new type of skin removal device that does not use a suction device. Hereinafter, the features of the present invention will be described. In order to clarify the correspondence with each part, parentheses are appropriately written.

  The thin skin removing device (thin skin removing device 1) includes a moving mechanism (vibrating portion 7 and main body portion 4) for moving coffee grounds in the traveling direction using vibration, and a direction crossing the coffee grounds moving in the traveling direction. A wind blowing section (blower wall 14) that blows out the wind, and a separation section (separating section 15) that is provided at a blow destination of the blown wind and separates an object to be removed carried by the wind. Features.

  In addition, the direction which crosses coffee grounds means 45-135 degree | times with respect to the advancing direction of coffee grounds, More preferably, it exists in the range of 60-120 degree | times.

  Thereby, since the thin skin removing device does not require a suction device, a suction path and a motor can be eliminated, the configuration can be simplified, and the size can be reduced.

The moving mechanism is
It has a rectangular main body (main body 4) that is long in the traveling direction, and a vibration section (vibration section 7) that vibrates the main body, and the wind blowing section extends over substantially the entire area of the main body. Blows the wind.

  As a result, the thin skin removing device can be blown in the middle while moving the main body that is long in the traveling direction, and the removal target is repeatedly wound up, thereby increasing the probability that the removal target is removed. .

  Moreover, the thin skin removing apparatus has a wind deflecting unit (wind deflecting unit 5) for changing the traveling direction of the wind.

  Thereby, the thin-skin removal apparatus can lengthen the path | route of the blowing wind until it reaches | attains a isolation | separation part, and can perform the selection of the ground coffee and the removal target object from which weight differs.

  Furthermore, in the thin skin removing apparatus, the separation part is provided on a back surface of the wind blowing part. As a result, the thin skin removing device causes the blown air to pass over the coffee grounds twice. The first time rolls up the object to be removed, and the second time, the heavy ground coffee grounds are rolled up at the same time. Can be returned to the main body (main body 4). Since this action is repeatedly performed while the coffee grounds remain on the main body, it is possible to reduce accidental elements and to accurately remove only the lightweight removal object.

  In the thin skin removing apparatus, the moving mechanism moves the coffee grounds in the traveling direction by using a vibration having directivity. Thereby, the thin-skin removal apparatus can perform both the stirring of coffee grounds and the progress in the traveling direction by vibration.

  The thin skin removing method is characterized in that the removal object conveyed by the blowing air blown in the direction crossing the coffee grounds moving in the traveling direction by vibration is separated. Thereby, only a lightweight removal object can be rolled up and induced | guided | derived to a isolation | separation part by blowing a blowing wind in the state which vibrated coffee grounds up and down.

<Other embodiments>
In the above-described embodiment, the case where the upper side of the wind deflection unit 5 is opened has been described. The present invention is not limited to this. For example, as shown in FIG. 7, the extending wind deflecting unit 305 is connected to the outer edge of the separating unit 15 from the outer wall 4 a, so that the direction other than the supply direction and the traveling direction may be closed. . Moreover, you may make it a closed system which seals except the supply part 11 and the discharge part 12. FIG. Thereby, it is possible to prevent the object to be removed and the coffee powder that have been rolled up by the blowing air from being scattered around.
Although not particularly described in the above-described embodiment, the auxiliary portion is parallel or substantially parallel to the bottom surface of the main body portion 4 from the direction of the discharge portion 11 toward the reverse direction that is opposite to the direction of coffee grounds. You may send a breeze. Thereby, the movement to the advancing direction of the light ground powder which floats with a wind can be selectively delayed, and the probability that a thin skin will be removed can be raised.

  The thin skin removing apparatus of the present invention can be used after grinding coffee beans in a store, for example.
