Abstract

PURPOSE:To surely peel and eliminate only the exodermis without damaging a bulb, by cutting stem and root parts, forming slits on the exodermis of the bulb, feeding the resultant bulb onto rotating rolls, provided side by side on a base plate and rotating in the same direction and jetting compressed air from the upper and lower nozzles. CONSTITUTION:Stem and root parts are cut by a cutter and slits are formed on the exodermis of a bulb, such as onion. The resultant bulb is then fed onto rotating rolls 2 and 3, provided side by side on a base plate 1 and rotating in the same direction and moved along the longitudinal direction by a conveyor unit 55 while being rolled on the rolls 2 and 3 with the exodermis being peeled off. The bulb is pressed against the rolls 2 and 3 by compressed air jetted from downwardly directing jetting nozzles 17 of the upper air pipe 16 provided above the rolls 2 and 3 and the exodermis is simultaneously peeled and eliminated. Furthermore, the exodermis is surely peeled and eliminated while jetting compressed air jetted from upwardly directing jetting nozzles 24 of the lower air pipe 23.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an apparatus for peeling scales of onions, garlic, chili peppers, etc.

Conventional technology In general, bulbs such as onions and large onions are widely used as cooking ingredients, but before they can be processed into shreds, the yellow-brown outer skin of the bulb must be peeled off. If you want to process large quantities of , 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 cut into pieces and used as cooking ingredients by blowing out air to peel them off.

To do this, conventionally, a roller conveyor is installed on the base that transports a large number of onions with the upper and lower halves cut off while rotating, and compressed air is sprayed onto the onions on the conveyor's transport path to peel off the outer skin. An onion peeling machine in which air supply nozzles are vertically adjustable and arranged in a row is known as Japanese Utility Model Application Publication No. 52-127098. In a scale peeling device that sprays the skin of a scale passing over the transfer section, a switching means sets the distance between the nozzle and the bulb placed on the transfer section to an optimum distance; A scale peeling device was disclosed in 1983, which is equipped with means for automatically horizontally swinging the scale section through which the nozzle passes through the transfer section.
This is known as Publication No. 154994, and these devices move the nozzle up and down according to the size and shape of the scale, in order to make it possible to exfoliate the outer skin regardless of the size and shape of the scale. The structure and operation were complicated and expensive.

In addition, an automatic onion peeling device that rotates a spiral baking shaft to move and transfer onions was developed in Japanese Patent Laid-Open No. 48-23982.
However, since this method rotates a spiral baking shaft, the contact surface between the shaft and the onion is large, so there is a risk of damage. After being peeled off, the epidermis was burned with a burner and then removed using a rotating brush and a fountain pipe.

Problems to be Solved by the Invention An object of the present invention is to address the above-mentioned drawbacks, to reduce the contact surface with the bulbs, eliminate the risk of damaging the bulbs, and to transport the bulbs reliably. To provide a bulb peeling device capable of reliably peeling off only the outer skin of the bulb in which a slit is formed using a long peeling nozzle in which the bulb moves.

Means for Solving the Problems The bulb peeling device of the present invention comprises a base, rotary rolls rotatably arranged in parallel on the base and rotating in the same direction, and provided above the rotary rolls. an upper air pipe having a downwardly directed injection nozzle; a lower air pipe having an upwardly directed injection nozzle provided below the rotating roll and opposite to the upper air pipe; It has a configuration characterized in that it consists of a conveyor that moves along the vehicle.

When the bulbs whose stems and roots have been cut by a cutting device and slits have been formed in the outer skin are fed onto rotating rolls arranged in parallel on a base and rotating in the same direction, the scales are transferred on the rotating rolls and the outer skin is cut off. It is moved along the longitudinal direction on the rotating roll by a carrier while being peeled up, and is pressed against the rotating roll by compressed air jetted from a downwardly directed injection nozzle of an upper air pipe provided above the rotating roll. The outer skin is exfoliated along the slits, and the outer skin is reliably exfoliated while spraying compressed air from an upwardly directed jet nozzle of a lower air pipe provided below the rotating roll, and the outer skin is surely exfoliated so that the rotating roll and the scale come into contact with each other. Make the surface smaller to prevent damage.
