Abstract

PURPOSE:Onions are fed to the conveying path at a prescribed time or distance interval to prevent that 2 or more onions stay in the peeling chamber. CONSTITUTION:Onions (a) with a size fitting to the inner diameter of the path 1 are continuously fed to the conveyor 40 at a prescribed interval to the position right beneath the cylinder 10. The onions are sucked by vacuum from the end 3 to pass through the path 1, while they are rotating rapidly, pushed out of the end 3 toward the center of the above peeling chamber 25. In the peeling chamber 25, whirling air flows cross to each other to colide at a high speed and blow off the peel (c) of the onion (a), while the peeled onions (b) colide to the deflector 60 above the peeling chamber 25 and come out of the outlet 26. The peels (c) go up through the duct 68, then go out.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an onion peeling device that sucks and supplies onions using a vacuum generated by blowing out compressed air, and blows and peels the onions.

To peel an onion, it has been common practice to first make vertical scratches in the onion with a knife, etc., and then blow compressed air onto the onion to blow the onion's skin off. It's amazing that it's being done.

In this conventional technology, it is necessary to make vertical scratches on the onions, which requires a huge amount of time and effort.
It was also a factor that led to the complexity of the device and the increase in cost.

Therefore, the present applicant researched and developed a device for peeling onions without making such vertical scratches and with the hair roots still attached, and filed an application earlier. The idea was that the cylindrical passage through which the onions flow had a fairly large inner diameter, and a plurality of onions of different sizes would flow together. Moreover, the separation chamber provided opposite the onion discharge end of this passage applies turbulent flow by blowing compressed air to the plurality of onions fed into the chamber, and thereby causes the onions to interact with each other. It was constructed into a medium-thick cylindrical chamber with a spherical enlarged middle part, so that the onion skins were blown off by rubbing them together, and then the peeled onions were discharged one after another. However, in reality, when a plurality of onions are stored in the spherical chamber, the wind speed is reduced, making it difficult to discharge the onions smoothly, and causing onions to become blocked in the separation chamber. If such a blockage phenomenon occurs, the onion will no longer flow through the passage, making it impossible to peel the onion.

Therefore, in the present invention, in order to prevent such a blockage phenomenon from occurring in the separation chamber, improvements are made to the passage through which onions flow and the structure of the separation chamber, and the onions are supplied at predetermined time or distance intervals. The object of the present invention is to provide an onion peeling device that has the following features.

The present 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 direct passageway (1) are continuously fed one by one by a conveyor device (40) directly below the cylinder (10) at a predetermined interval.

A compressed air blowing device (15) is provided on the upper outer periphery of the cylinder (10).
), compressed air is blown out at high speed from the compressed air outlet (7) of the shell blowing device (15).
However, when the compressed air enters the compressed air introduction path (16) from the introduction port (17), it first spirals and rotates due to contact with the spiral groove (12) provided on the outer peripheral wall of the cylinder (10). Initially, the air is further bent as it passes through the spiral groove (9) between the spiral blades (11), and it becomes a swirling swirling airflow from the compressed air outlet (7) through the inclined passageway (18). Therefore, the inside of the conical swirling airflow, that is, the direct passage (1) of the cylinder (10)
Vacuum pressure is generated at the discharge end (3) of the onion (a), and when the onion (, ) is located directly under the suction end (2) of the direct passage (1), the vacuum pressure increases rapidly. Road (
1) Inhale rapidly.

While the onion (a) is sucked in and rapidly ascends through the straight path (1), rotation is imparted by the spiral groove (4) provided in the inner circumferential wall of the cylinder (10). Therefore, the onion (a)
It passes straight through the direct passageway (1) while rotating, and is discharged from its discharge end (3), and combined with the effect of the swirling airflow, it is discharged in the correct direction to the center of the upper separation chamber (25). In the separation chamber (25), while the onion (a) passes through the separation chamber (25), the swirling airflow collides with the onion (a) in a crosswise manner at a high degree of rotation, so that the peel part ( C) is blown away and the skin is peeled off cleanly.

The peeled onion, that is, the peeled onion (b), is transferred to the left rotating body (61) and the right rotating body of the direction changing device (60), which are rotating in opposite directions in the upper part of the separation chamber (25). (61)' slanted bar (66).

(6t5)', the horizontal component of the reaction force causes the ball to change direction laterally, and is discharged to the outside through the outlet (26) and further through the peeled ball outlet pipe (27).

On the other hand, the skin portion (c) of the peeled ball (b) is mostly formed between the drum-shaped rotating bodies (65) and (65)' of the left rotating body (61) and the right rotating body (51)'. The waste rises through the passageway (67), is led to the separation device (80) via the skin outlet pipe (68), is captured by the cyclone tube (81), and is discharged to the outside via the skin outlet pipe (84). Ru. Part of the peeled ball (b) and a part of the skin (c)
) is separated from the peeled balls (b) through a second peeling outlet pipe (69) branched from the peeling outlet pipe (27), and then separated from most of the peeled balls (C) through a cyclone pipe (81). - It is discharged to the outside through the skin outlet tube (84).

In the above case, even if the peeled ball (b) collides with the inclined par (66), (66)', the bar (66)
, (66)′ buffer (65), (,65
)', there will be no dents or damage to the peeled ball.

In the present invention, as is clear from the above, onions (a) are supplied to the suction end (2) of the direct passage (1) at intervals in time or distance using a suitable conveying means. good. Then, since vacuum pressure is generated in the direct passageway (1) by blowing compressed air, the onion (1) is sucked in and discharged through its discharge end (6) into the separation chamber (25). I can do it. The direct passage (1) is a straight passage through which only one onion can pass, and the separation chamber (25
) also stores two or more onions discharged from the discharge end (5) of the direct passage (1), and while the onions (a) pass through the separation chamber (25), , the skin is peeled off by the impact of compressed air.

Therefore, according to the present invention, there is no possibility that the onion is blocked in the separation chamber without being discharged, and the suction supply and peeling of the onion can be performed smoothly and reliably.
