Description

Onion peeling machine

The present invention relates to an onion skin peeling machine, which more specifically describes an onion peeling machine, which simplifies the machine configuration and reduces the size and manufacturing cost of the machine, while greatly enhancing the peeling force of the shell surrounding the scales.

The onion is mainly covered with thin yellowish brown shell of scaly stem used for edible use, so it is necessary to remove the peel as well as the tap and the root of the onion to use for edible use. In particular, onions are mainly used as a main ingredient in most dishes. Their roots and shells have been peeled off, and there have been many demands for first-handed onions, and techniques for efficiently processing large amounts of onions have been developed.

For example, an onion automatic peeler of the registered utility model (Y1) 20-0254522 (Nov. 24, 2001) of the Republic of Korea is provided, which comprises a plurality of blade rollers for carrying out preliminary peeling work, There is a push plate with a handle on which the onion is placed and pressed at the top thereof, a guide guide for guiding the pre-peeled onion to the automatic peeling device, an automatic nozzle device comprising an air nozzle, a pair of rotating rollers, And a drawer-type peel collecting network for collecting the peeled peel.

However, the above technique has the disadvantage that the peel of the onion is only peeled, and the faeces and the root are separately worked, and the onion is rolled between the rollers, which causes problems such as damage of the scales in the peeling process. There is a problem that the peeling rate is lowered and the consumption of compressed air is increased, so that the power consumption is increased.

Accordingly, the present applicant has invented and registered an onion peeling machine (10-1415318 (Apr. 14, 2014)) for the purpose of solving the above-mentioned conventional problems. A conveyance conveyor configured to be installed at a predetermined interval and to be driven by a driving motor, wherein a pair of chains provided on an upper portion of a base are provided with an installation panel having an installation groove for installing an onion; A supporter standing on the base to be positioned at an intermediate upper portion of the conveying conveyor; A clamping conveyance belt assembly including a pair of conveyance belts installed on the supporter and configured to press both sides of the onion conveyed by the conveyance conveyor and convey the same to a clamping state; A lower cutting section provided on the base of the conveying conveyor so as to cut off the lower root portion of the onion wave in a state of being clamped by the conveying belt of the clamping belt assembly; An upper cut section provided on the supporter to cut the upper nip of the onion in a state of being clamped by the conveyance belt of the clamping belt assembly; A thin skin provided on the supporter so as to peel the skin from the onion which is transported by being placed on the seat panel of the conveying conveyor in the state that the root and root portions are cut by the upper and lower cut portions; An onion discharge chute installed on the gas so as to discharge the peeled skin from the cuts at the upper and lower cuts, an onion discharge chute installed on the gas so as to discharge the peeled onion from the skin conveyor, ; And a sensing sensor unit for sensing the number of revolutions of the shaft on any one of the shafts to which the sprocket is coupled and the base.

However, the above-mentioned invention of the preamble of the present invention is characterized in that it has a large volume and a large space limitation in installation because it cuts off the tips and roots of the onion and peels it, and fails to provide functionality satisfying all the various sizes of onions, There was a problem that the surroundings were messed up by the onion skin and the dust.
