Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a device for peeling scales of onions, garlic, chili peppers, etc.

PRIOR TECHNOLOGY In general, scales such as onions and giant sardines are widely used as cooking ingredients, but before they can be shredded, the yellow-brown skin around the outer periphery of the scales must be peeled off. If you want to process large quantities, you have no choice but to rely on mechanical methods.

Blast air is the most effective means of peeling off the outer skin, and in the onion peeling process, compressed air is sprayed onto the bulbs placed in the transfer section to remove the skin, and then a shredding process is carried out. The scales were then shredded and used as a cooking ingredient by blowing out air to peel them off.

To this end, conventionally, a roller conveyor is installed on the machine to transport a large number of onions with the upper and lower stems cut off while rotating, and on the moving path of the conveyor,
An onion peeling machine is known as Japanese Utility Model Application No. 52-127098, in which air supply nozzles for blowing compressed air onto onions and peeling off their outer skins are arranged in a vertically adjustable manner.
Further, in the scale peeling device, a nozzle is disposed facing above the transfer section, and air is injected from the nozzle to exfoliate the outer skin of the bulbs passing over the transfer section. A bulb peeling device is provided, comprising a switching means for setting the distance to the bulb placed at an optimum distance, and a means for automatically swinging the nozzle horizontally over the bulb passing through the transfer section. This is known as Japanese Utility Model Publication No. 57-154994, and in order to make it possible to exfoliate the outer skin regardless of the size and shape of the scale, the nozzle can be moved up and down according to the size and shape of the scale. The structure and operation are complex in order to move to
It was becoming expensive.

The nozzle member includes a conveying member that conveys and discharges onions in one direction, and a nozzle member that is located above the conveying member and can direct the opening toward the onions and spray pressurized fluid. is provided so that it can move forward and backward in a straight line parallel to the onion, etc. at a speed faster than the advancing speed of the onion, etc., and repeatedly swings in the left and right directions perpendicular to the direction of forward and backward movement around the nozzle support point. This automatic peeling device for onions, etc. is designed to peel off the outer skins of onions with irregular standard dimensions, shapes, sizes, etc. in the front, back, left and right directions using pressurized fluid. is known from Japanese Patent Publication No. 51-11193, but this also had a complicated structure and operation because the nozzle was moved.

Purpose of the Invention The purpose of the present invention is to eliminate the above-mentioned drawbacks, eliminate the need to move the nozzle up and down according to the size and shape of the bulb, simplify the structure and operation, and provide an inexpensive method that does not depend on the size and shape of the bulb. To provide a scale peeling device capable of reliably peeling off only the outer skin in which slits are formed without removing the slits from the scales.

Structure of the Invention The scale peeling device of the present invention has a conveyor belt whose cross section is open at a predetermined angle and has a different transfer speed, and an upper air conveyor belt having a downwardly directed jet nozzle provided above the conveyor belt. It has a structure characterized in that it consists of a pipe and a lower air pipe provided below the conveyance belt and having an upwardly directed jet nozzle.

The outer skin of the onion 15 is also peeled off by the compressed air ejected from the ejection nozzle 23 of the lower air pipe 21, and since the transfer speeds of the roller chains 9 and 9' are different, the onion 15
As shown in the figure, by rotating and moving on the chain, the outer skin comes into contact with the roller link plate 10 and is reliably peeled off. It is discharged to the outside from the discharge hole 1b along the slopes 1a and 1a'.

Note that the upper air pipe 17 and the lower air pipe 21 may each be moved a certain distance in the same direction at the same speed as the roller chains 9 and 9', and then returned to their original positions at high speed. The chopped onions are sent to a shredding device (not shown) for the next process.
