Description

TECHNICAL FIELD The present invention relates to a method and apparatus for peeling the skin of a pickled scallion or the like by blowing fumarolic gas onto the outer surface of the pickled scallion or the like and effectively utilizing the wind pressure of the fumarolic beam.

As a nozzle for peeling green onions using artificial wind pressure, as in Patent Document 1, uniform pressure liquid is concentrated in a fan shape with an obtuse radial angle toward the front from the nozzle mouth and a thin width. A structure has been proposed in which the liquid is sprayed, but the biggest drawback is that it gets wet because it sprays liquid, which accelerates deterioration. Also, the surrounding area will get wet.
On the other hand, in the structure of Patent Document 2, the outlets of a pair of air nozzles facing each other in the front-rear direction are formed in a horizontally elongated flat shape. , is troublesome. There is also the risk of dust being blown up.

Focusing on these problems, as in Patent Document 3, a nozzle for peeling the skin of the scallions using the wind pressure of the beam-like fumaroles is arranged around the scallions to effectively and instantaneously peel the skins. We proposed a peeling device with a simple structure that does not raise dust. 1 to 5 show details thereof, and FIG. 1 is a perspective view showing the state of use of a device for peeling shallots. Compressed air from a compressor connected to an outer cylinder 1 passes through a hose 2 Then, it blows out from the air holes opened in the wall of the inner cylinder 3 in the converging direction (opposite to the radial direction), and peels off the outer skin of the island shallot 4 inserted into the inner cylinder 3 from above. The island shallots are held one by one with the fingers 5 and supported with the fruit part (also called bulb) facing down.

FIG. 2 is a longitudinal sectional view of the peeling device, in which the inner cylinder 3 is attached to the upper end of the lower support cylinder 6 via the relay cylinder 7 . An upper outer cylinder 11 and a lower outer cylinder 12 having a large diameter are attached to the outside of the inner cylinder 3 with a gap, and the upper end and the lower end are airtightly connected. The cylindrical body 8 is a connecting cylinder that connects the upper outer cylinder 11 and the lower outer cylinder 12 on the outside.
As shown in FIG. 3(1), the inner cylinder 3 has a small-diameter cylindrical portion 32 on the upper side of the tapered portion 31 and a large-diameter cylindrical portion 33 on the lower side thereof. Air holes 9 are formed at the boundary between the tapered portion 31 and the small-diameter cylindrical portion 32 on the upper side. A plan view of this is shown in FIG. 3(2). The positions and angles of the center lines of the air holes 9 are assumed to be indicated by solid lines and dashed lines.

Since it is difficult to understand when the solid line and the broken line are mixed as in FIG. 3, only the solid line is illustrated in FIG. As shown in FIG. 4(2), the island scallion to be inserted into the inner cylinder 3 from the opening 34 at the upper end is assumed to be a perfect circle 4', and the air hole 9 is formed so as to eject compressed air in the direction of the tangential line on the right side of the perfect circle 4'. . Also, (1) as shown in the figure, the compressed air is jetted forward and downward (toward the island shallot 4) at an angle. The inclination angle is 50 to 70 degrees, the inner diameter is 0.7 to 2.0 mm, and the deviation from the center is 1.0 to 2.5 mm. Since there are 6 holes in one lap, the intervals are 60 degrees.
FIG. 5 shows only the dashed line, and the island scallion is assumed to be a perfect circle 4', and the air holes 9 are opened so as to blow out compressed air in the direction of the tangential line on the left side as shown in (2). As a result, the island scallions 4 generate a clockwise rotational force. (1) As shown in the figure, it erupts at an angle of 40 to 60 degrees, tilting forward (towards island shallots 4). The inner diameter is 0.7 to 2.0 mm, and the deviation from the center is 1.5 to 3.0 mm. Since there are six openings in one circumference, the intervals are 60 degrees, and the deviation angle from the solid line air holes 9 is about 30 degrees.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a diagram showing a fumarolic ring according to the present invention, where (1) is a perspective view, (2) is a plan view, and (3) is a left side view. FIG. 5 is a perspective view showing another example of the attachment structure of the jet ring according to the present invention; FIG. 4 is a cross-sectional view at the position of one fumarole 14; It is a cross-sectional view for comparison with a conventional structure, the left half is the cross-sectional structure of the air hole in FIG. 2, and the right half is the cross-sectional shape of the fumarole of the present invention.

Next, an embodiment will be described as to how the peeling apparatus using the beam-like jet pressure according to the present invention is practically embodied. In the present invention, as shown in the perspective view of FIG. 6(1), a circular tube 15 having a plurality of fumaroles 14 is formed in the shape of a float, and a fumarole ring 16 is placed horizontally on the upper end of the support cylinder 6 shown in FIG. The compressed air inlet pipe 17 connected to the fumarolic ring 16 is connected to the compressor. A plan view of this fumarolic ring 16 is shown in FIG. 2. In the fumarolic ring 16, as in FIGS. It is also possible to open the fumaroles 14 on one side as shown in the figure, and to prevent rotation by the fumaroles 14 omitted on the other side, hold the scallions with your fingertips. It is possible. The left side view of this fumarolic ring 16 is shown in Fig. 3, and the fumarolic holes 14 are inclined downward at an angle of 45 degrees with respect to the assumed shallots 4' as shown in Figs. is attached.

Such a jet ring 16 is placed horizontally on the upper end of the support tube 6 shown in FIG. 2 and fixed by welding or adhesive. However, as shown in FIG. 7, the jet ring 16 may be horizontally and airtightly fixed to the upper end of the relay pipe 18 into which the upper end of the support cylinder 6 is inserted. In addition, the support tube 6 is constructed so that a separately provided discharge duct can be connected to an inexpensive PVC material in order to hygienically dispose of dust, dirt, and irritating odors without reaching the operator.
As shown in FIG. 6(2), the actual fumarolic ring 16 was made of an aluminum pipe with an outer diameter of 14 mm and a wall thickness of 3 mm, and formed into a ring shape with an inner diameter of 30 mm and an outer diameter of 58 mm. Then, three holes of 1.6 mm are made at 120° intervals, and are shifted 2.5 mm to the right from the 45° center direction to form fumaroles 14 . . . As a result, the exhaust direction becomes a vortex that rotates counterclockwise only. Therefore, although the scallions 4' are also subjected to a counterclockwise rotation force due to the fumarolic beam, the scallions 4' are held by the fingertips so that they do not rotate, so they do not rotate counterclockwise.

If a low-cost product is desired, a pipe made of synthetic resin may be used instead of the aluminum pipe 12 made of metal, bent into a ring shape, and adhered annularly with an adhesive. Only the blowholes 14 may be made of a metal nozzle that is hard to wear, but the blowholes 14 may also be made of synthetic resin to make the product short-lived.

FIG. 9 is a diagram comparing the cross-sectional shape at the position of the fumarole 14 with the structure of FIG. 2. The left half is the structure of FIG. An example is provided. As is clear from this figure, the front-downward fumaroles 14 of the present invention are oriented tangentially to the inner wall of the circular tube 15 and obliquely downward toward the peeled portion of the shallots 4 . By opening the opening, the distance to the target scallion 4 is minimized, and as a result, the impact pressure on the scallion 4 is increased. As a result, since the working pressure can be set low, the consumption of compressed air can be reduced, and a compact and inexpensive compressor can be used. In addition, from the compressor to the blowholes 14, the structure is such that there are no obstacles that hinder the smooth advancement of the compressed air.

As described above, the tube into which the scallions are inserted vertically from top to bottom and which also serves as a support for the device is provided vertically, and the upper end of the tube is provided horizontally with a fumarolic ring formed of a circular tube in the shape of a floating ring. It is fixed and connected to the compressor by piping. In addition, since it is opened in the tangential direction of the inner wall of the circular tube forming the fumarolic ring and diagonally downward toward the scallions, the distance from the scallions is the shortest, and the impact pressure is increased. As a result, the working pressure can be set low, so the consumption of compressed air is small, and a compact and inexpensive compressor is sufficient.
