Abstract

PROBLEM TO BE SOLVED: To provide a bucket conveyor for tea manufacture configured so that tea leaves do not adhere to a bucket for conveying tea leaves.SOLUTION: In the bucket conveyor 1 for tea manufacture, a rubber member whose surface is rugged is stuck to a portion where the bucket 2 for conveying the tea leaves comes into contact with the tea leaves.

Description

  The present invention relates to a tea bucket conveyor for conveying tea leaves in a tea making process.

  In the tea making process, a tea bucket conveyor is used as a means for transporting tea leaves from below to above. In these, rollers are installed up and down, a belt is stretched between an upper roller and a lower roller, and a large number of bowl-shaped tea leaf conveying buckets are attached thereto. The belt between the upper and lower rollers is generally made of non-metallic material such as a resin belt, and the tea leaf bucket is made of metal (surface-treated steel plate, SUS, etc.).

  It is known that tea leaves are washed and dehydrated in the tea making process, mainly in Kagoshima Prefecture, against ash fall on Sakurajima. Although the surface moisture of the cleaned and dehydrated tea leaves is generally taken, it is not perfect, so in order to completely remove the surface moisture, hot air is then applied from the outside of the rotating drum of the wire mesh, and the tea leaves inside Use a tea leaf processor to pass through. The take-out part of the dehydrator is close to the floor, and the tea leaf processor's inlet is above (about 2 to 3 m from the floor), so the tea leaves taken out from the dehydrator are received by a vibrating conveyor and then by a bucket conveyor. It was necessary to raise it upward. Immediately after the start of operation, it is good, but after a while, a phenomenon occurs in which water slightly adhered to the tea leaves adheres to the tea leaf conveying bucket and further adheres to the tea leaves themselves.

  For this reason, although the thing like the sheet | seat 9 of patent document 1 was devised, it was not put into practical use.

Actual Zenpira 2-28815 specification

  According to the conventional bucket conveyor for tea making, the tea leaves adhere to the bucket for conveying the tea leaves, and cleaning after the completion is very laborious and laborious. There was also a problem that the tea leaves that were attached more than that and deteriorated over time sometimes peeled off and mixed with high quality fresh tea leaves. That was a major problem directly related to the quality degradation of the product.

  In order to solve the above-described problems, an object of the present invention is to provide a tea bucket conveyor that does not allow tea leaves to adhere to the tea leaf conveying bucket.

  The first means of the present invention is a tea-making bucket conveyor characterized in that, in the tea-making bucket conveyor, a member having an uneven surface is attached to a contact portion of the tea-leaf conveying bucket with the tea leaf. The second means is a tea bucket conveyor characterized in that the surface of the first means having an uneven surface is made of rubber.

  According to the present invention, the contact between the tea leaf conveying bucket and the tea leaf changes from surface contact to point contact, and even if moisture adheres to each, the tea leaf does not adhere to the tea leaf conveying bucket. Easy to clean. In addition, as before, the tea leaves that have adhered and deteriorated over time are not mixed, which contributes to quality improvement.

FIG. 1 is an installation example of a tea bucket conveyor. FIG. 2 is a perspective view of the tea leaf carrying bucket. FIG. 3 is a detailed view showing a contact portion between the tea leaf carrying bucket and the tea leaf. FIG. 4 is a detailed view showing a conventional tea leaf transport bucket and tea leaf contact portion.

  FIG. 1 is an installation example, and the tea leaves move from the tea machine 6 on the left to the tea machine 7 on the right. At this time, the tea leaves are taken out from the lower part of the tea making machine 6 to the vibrating conveyor 8, and the tea leaves are transferred from the upper part of the tea making machine 7 by the belt conveyor 9. A bucket conveyor 1 is required. At this time, the tea making machine 7 may be a twister with a relatively high water content in the manufacturing process. The tea leaf container for storing tea leaves, the dehydrator after washing the tea leaves, the steamer, the leaf punching machine, There is no limitation such as roughing machine and twisting machine. It is effective when transporting tea leaves with a lot of moisture.

  The tea-making bucket conveyor 1 has rollers 3 and 4 installed up and down, a belt 5 is stretched between the upper roller 3 and the lower roller 4, and a large number of bowl-shaped tea leaf conveying buckets 2 are attached thereto. is there.

  FIG. 2 is a perspective view of the tea leaf transport bucket 2, and the tea leaf transport bucket 2 is usually made of metal 11, and a member 12 having an uneven surface is attached to the contact portion of the metal 11 with the tea leaf. is there. In FIG. 2, the surface 12a of the tea leaf conveying bucket 2 is not affixed with the uneven member 12 but may be affixed.

  FIG. 3 shows the details of the contact portion between the tea leaf conveying bucket 2 and the tea leaves 10 whose surface is uneven. The contact portion between the tea leaf 10 and the tea leaf transport bucket 2 is only a convex portion, and the tea leaf 10 does not stick to the tea leaf transport bucket 2 because of point contact. When the tea leaf transport bucket 2 is reversed at the upper portion of the tea bucket conveyor 1, the tea leaf 10 falls away from the tea leaf transport bucket 2.

  The detail of the contact part of the conventional bucket 2 for tea leaf conveyance and the tea leaf 10 is shown in FIG. The surface of the metal 11 of the tea leaf transport bucket 2 is smooth, and when water adheres to the surface of the tea leaf 10, the tea leaf 10 and the metal 11 of the tea leaf transport bucket 2 are adhered by the surface tension of water. When sticking due to the surface tension of water, even if the tea leaf transport bucket 2 is inverted at the top of the tea bucket conveyor 1, the tea leaf 10 is unlikely to be separated from the metal 11 of the tea leaf transport bucket 2, and tea leaves that do not fall off are generated. The tea leaves attached to the metal 11 of the tea leaf conveying bucket 2 may be peeled off when the tea leaves have run out of time, or may not be peeled off until cleaning.

  As the member 12 having an uneven surface, there are rubber, artificial grass, SUS wire mesh, etc. Among them, rubber is the most effective. When affixing to the tea leaf conveying bucket 2, a rubber mat or the like may be cut to an appropriate size and affixed with an adhesive and rivets. Of course, the rubber mat used is made of a material that complies with the Food Sanitation Law.
