Apparatus for washing and husking bulbs using High pressure water}

The present invention relates to a device that grows in the soil, such as potatoes, sweet potatoes, carrots, etc., and peels off the shells of the edible bulbs, or peels the shells. The present invention relates to a bulb cleaning and stripping apparatus using high pressure water to remove soil or shells on the surface by spraying high pressure water onto a surface of a horizontally moving bulb while rolling along a roller.

Most of the bulb cleaning and stripping devices developed so far have been mechanical stripping devices that use a rotating kumgang (sandpaper) or brush to shave the shells of the bulbs. Such mechanical bulb cleaning and stripping apparatus (hereinafter abbreviated as 'bulb stripping apparatus') is largely classified into a drum type stripping device and a roller type stripping device. Drum-type stripping device forms stripping net with metal steel or brush on the inner circumferential surface of the cylindrical drum and rotates the drum with a driving motor, so that the bulb injected into the stripping net collides with the stripping net by centrifugal force so that the shell is stripped. will be.

However, the mechanical stripping device or the steam stripping device according to the prior art has a lot of difficulty due to the large bulb loss rate and difficulty in storing and transporting for a long time. Therefore, the present inventors have developed a new type of bulb cleaning and stripping apparatus capable of processing a large capacity for use in bulb growers, having a low bulb loss rate, and less surface damage, so that storage and transportation can be performed for a relatively long time.

The present invention is to remove the soil on the surface by spraying high-pressure water to the surface of the bulb to move along a plurality of screw rollers instead of using a mechanical stripping method such as diamond or brush to minimize the loss rate of the bulb or The present invention provides a bulb cleaning and stripping apparatus using high pressure water in which a fluid stripping method is applied to strip the shell.

The present invention provides a bulb cleaning and stripping apparatus capable of continuously cleaning or stripping a large amount of bulbs by arranging a plurality of screw rollers in a horizontally rotatable manner and installing a plurality of high-pressure water nozzles that are rotated back and forth on the top. will be.

The present invention also provides a bulb cleaning and stripping apparatus that can freely select the cleaning function and the stripping function by adjusting the water pressure of the high pressure water sprayed on the surface of the bulb or the height between the screw roller and the high pressure nozzle.
