Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention separates (peels) unnecessary or edible epidermis (lower leaf) wrapping the outer surface of agricultural products such as leeks, burdock roots, cucumbers, eggplants, carrots, and yams. The present invention relates to a crop peeling device used for work.

[0002]

2. Description of the Related Art Conventionally, as a device for separating the onion epidermis of the above-mentioned example, for example, after the onion conveyed by a conveyor is lifted by a pair of supporting members, a hollow cylinder is opposed to the root end of the onion. Move horizontally to and insert almost the entire length of the leek into the inside of the cylinder. There is a device (Japanese Patent No. 3127396) that separates unnecessary epidermis by blowing air discharged from a plurality of nozzles provided inside the tubular body onto the outer peripheral surface of the stalk portion of the leek while moving the tubular body backward.

[0003]

However, in the above-mentioned device, since the discharge pressure of the air blown to the whole length of the stalk of the leeks is constant, if the epidermis of the stalk is soft, a plurality of epidermis will be treated at once. It may be peeled off or may damage the outer peripheral surface of the stem portion, and it is difficult to peel off the epidermis to a predetermined number and thickness. Also, if the air discharge pressure is lowered,
There is a problem that it is difficult to peel off the epidermis covering the starting end side of the stalk and to separate the epidermis from the end side of the stalk.

As another conventional example, a device for separating unnecessary skin by spraying air discharged from a nozzle, for example, on the outer peripheral surface of a stalk of a leek held in a substantially vertical posture (Japanese Patent Laid-Open No. 2001-163). However, similar to the above,
Since the discharge pressure of the air blown over the entire length of the stalk of leeks is constant, there are problems that the epidermis of a plurality of sheets are peeled off and the outer peripheral surface of the stalk is damaged.

In view of the above problems, the present invention switches the fluid discharged by the fluid discharge means to a predetermined discharge pressure while moving the fluid discharge means along the outer surface of the agricultural product.
An object of the present invention is to provide a crop peeling device capable of reliably and smoothly separating the epidermis of an unnecessary or edible crop without damaging the outer surface of the crop.

[0006]

The present invention relates to a crop peeling device for spraying a fluid discharged by a fluid discharging means onto an outer surface of a crop, and separating the epidermis of the crop by the discharge force of the fluid. A moving means for moving the fluid discharging means along the outer surface of the crop from a peeling start section to a peeling end section of the crop, and a fluid discharged by the fluid discharging means to an outer surface portion of the crop to which the fluid is sprayed. According to another aspect of the present invention, there is provided a crop peeling device including a discharge pressure switching unit that switches the discharge pressure to a predetermined value.

The above-mentioned agricultural products can be composed of long agricultural products such as leeks, burdock roots, asparagus, cucumber, eggplant, carrots and potatoes. Further, the fluid can be composed of gas such as air or gas, liquid such as tap water or distilled water, and solvent. Further, the fluid discharge means is, for example, a gas supply source that supplies air or gas, a skin removing member connected to a fluid supply source such as a liquid supply source that supplies tap water, distilled water, or the like, and a discharge nozzle of the air discharge unit. Or an injection device or the like. Further, the moving means may be, for example, a main body portion or a unit portion of the peeling unit, a movable frame, a chain, a sprocket, a guide rail, a motor or a solenoid,
It can be configured with an air cylinder or the like. Further, the discharge pressure switching means can be composed of, for example, an electromagnetic valve, a motor for opening and closing the valve, a cam, or the like.

That is, while moving the fluid discharge means from the peeling start section to the peeling end section along the outer surface of the crop, the discharge pressure of the fluid discharged by the fluid discharge means is switched according to the portion to which the fluid is sprayed. A predetermined discharge pressure (for example, high pressure, medium pressure, low pressure, etc.) is switched by means. When the fluid discharge means moves in the peeling start section of the agricultural product, the epidermis in the peeling start section is peeled off by the high-pressure fluid. When the fluid discharge means moves from the peeling start section to the peeling end section, the peeled epidermis is continuously peeled by the low-pressure fluid from the peeling start section to the peeling end section. When the fluid discharging means moves through the peeling end section of the agricultural product, the epidermis peeled up to the peeling end section is separated at once by the high pressure fluid.

As an embodiment, when the fluid discharge means moves to the peeling start section and the peeling end section of the agricultural product, the discharge pressure switching means corresponds the fluid discharged by the fluid discharge means to each section. When the fluid discharge means moves between the peeling start section and the peeling end section of the crop, the fluid discharged by the fluid discharge means is switched to a high pressure suitable for separating the outer skin of the crop. It is possible to provide a switching control means for switching to a low pressure suitable for separating the skins on the outer surfaces of the crops corresponding to the intervals.

Further, the fluid supply source connected to the fluid discharge means supplies a high-pressure fluid suitable for separating the skin on the outer surface of the crop corresponding to the peeling start section and the peeling end section of the crop. A high-pressure fluid supply source and a low-pressure fluid supply source that supplies a low-pressure fluid suitable for separating the epidermis on the outer surface of the corresponding crop between the peeling start section and the peeling end section of the crop. You can

[0011]

According to the present invention, while the fluid discharge means is moved along the outer surface of the crop, the discharge pressure of the fluid sprayed on the outer surface of the crop is set to a predetermined discharge pressure according to the portion to which the fluid is sprayed. By switching to, the epidermis can be reliably and smoothly separated into a predetermined number or thickness without damaging the outer surface of the crop, and the work of separating the epidermis of an unnecessary or edible crop is simple and easy. You can do it.

Along with the moving means for moving from the peeling start section of the crop to the peeling end section and the fluid discharged by the fluid discharge means are switched to a predetermined discharge pressure according to the outer surface portion of the crop on which the fluid is sprayed. A crop peeling device having a discharge pressure switching means. 2. When the fluid discharge means moves to the discharge pressure switching means in the peeling start section and the peeling end section of the crop, the fluid discharged by the fluid discharge means corresponds to each section on the outer surface of the crop. When the fluid discharge means moves between the peeling start section and the peeling end section of the crop, the fluid discharged by the fluid discharge means is switched to a high pressure suitable for separating the epidermis of The crop peeling device according to claim 1, further comprising switching control means for switching to a low pressure suitable for separating the outer skins of the crops corresponding to the spaces. 3. A fluid supply source connected to the fluid discharge means supplies a high-pressure fluid suitable for separating an outer skin of a crop corresponding to the peeling start section and the peeling end section of the crop. A high-pressure fluid supply source, and a low-pressure fluid supply source for supplying a low-pressure fluid suitable for separating the epidermis on the outer surface of the crop corresponding to between the peeling start section and the peeling end section of the crop. Item 1. A crop peeling device according to item 1.
