Abstract

PURPOSE:To prevent the scattering of the fragments of skin in open air, by attaching a skin transfer pipe to the turning device of peeled onion, and introducing the skin to a cyclone separator. CONSTITUTION:An onion (a) having a size matched with the peeling path 1 is transferred with the conveyor 60, and lifted in the path 1 by the sucking action caused by the flow of compressed air blown through the spiral groove and the blowing device 15. The onion is rotated by the spiral groove 4 in the path 1, and peeled. The peeled skin is blown off in the separation chamber 25 by the blown air stream, and the peeled bulb (b) is discharged by the direction changeover device 30 consisting of a rotor through the outlet tube 27. The skin is transferred to the cyclone-type separator 50, and discharged through the pipe 50. Air is exhausted through the exhaustion pipe furnished with a silencer.

The line of this embodiment is constructed as described above, and its operation will be described next.

Onions having a particle size that matches the inner diameter of the passageway (1) are continuously fed one by one at a predetermined interval directly below the cylinder (10) by a suitable conveyor device (60). Since a compressed air blowing device (15) is provided on the upper outer periphery of the cylinder (10), compressed air is blown out at a high speed from the compressed air blowing port (or mouth) of the blowing device (15). The compressed air line runs from the inlet (17) to the compressed air inlet path (16).
), first the spiral 1 provided on the outer peripheral wall of the cylinder (10)
11 (12), it begins to spirally move, and when it passes through the spiral groove (9) between the spiral blades (11), it is further bent, and the compressed air is blown through the inclined passageway (1B) e. The air flows out from the outlet (7) in a conical shape as a spiral swirl. Therefore, a vacuum pressure is generated inside the conical swirling airflow, that is, at the discharge end (6) of the passageway (1) of the cylinder (10), and the vacuum pressure is applied to the passageway (1).
When the pressure onion (a) is located directly below the suction end (2) of the onion, the pressure increases rapidly, so that the onion (-) is rapidly sucked into the passage (1).

While the onion (a) is sucked in and moves rapidly up the passageway (1), rotation is imparted by the spiral #1 (4) provided on the inner circumferential wall of the cylinder (10). Therefore, the onion (a)
rotates through the passage (1), passes straight from the front, and reaches its discharge end (
6), and combined with the effect of the swirling airflow, the air is ejected in the correct direction to the center of the upper separation chamber (25).

In the separation chamber (25), while the onion (mu) passes through the separation chamber (25), the swirling air currents collide with each other at high speed in a cross-shaped manner, so that the skin portion (C) of the onion (a) Blow away and clean the skin′? r: Stripped off.

An onion whose skin has been removed, that is, a peeled onion (b),
The left rotating body (
31) and the inclined bar (56) of the right rotating body (51)'.
), (36)', is turned laterally by the horizontal component of the reaction force, and is discharged to the outside through the outlet (26) and further through the peeled ball outlet pipe (27). The bar where the peeled ball (b) is inclined <56), (
56) Even if it collides with ', the no<-' (56).

Because of the cushioning bodies (35) and (55)' covering (36)', no dents or damage will be caused to the ball (b).

On the other hand, the skin portion (e) of the peeled ball (b) is mostly formed between the drum-shaped rotating bodies (55) and (55)' of the left rotating body (61) and the right rotating body (31)'. The cyclone tube (51) rises together with the air through the nuclear separation device (50) through the skin outlet pipe (3B) and is introduced into the separation device (50). ), while the purified air is released to the atmosphere through the air exhaust pipe (62).The skin part (e) collected at the bottom of the O cyclone pipe (51) is Furthermore, the air is blown out through the skin outlet pipe (54) by the air nozzle (55). In addition, a part of the skin part (C) that is led out together with the peeled ball (b) passes through the second skin outlet pipe (69) branched from the peeled ball lead-out pipe (27), and then passes through the peeled ball (1). )
), and then passed through the cyclone pipe (51) together with most of the skin part (C) and discharged to the outside as described above. Note that the separation device (50) is a silencer (56).
According to the present invention, the skin part separated from onions (fine pieces of skin, hair root fragments, dust, etc.) can be reduced. ,
It includes. ) is introduced into the separator together with the exhaust gas, the skin part in the nuclear exhaust gas is captured by the separator, and the exhaust gas is purified before being released into the atmosphere, so it does not cause environmental pollution. Additionally, exhaust noise can be muffled due to the muffler surrounding the separation device.
