TECHNICAL FIELD OF THE INVENTION
The present invention relates to a tea brewing and drying machine such as a rough rubbing machine and a middle rubbing machine, and more particularly, to an arrangement structure of rubbing hands and leaves used in the tea brewing and drying machine. The arrangement structure according to the present invention is suitable for producing finely twisted tea leaves by creating different processing environments in the kneading drum of the kneading dryer.
[0002]
[Prior art]
Tea leaves are produced after steaming fresh leaves, followed by a coarse kneading step, a kneading step, a medium kneading step, and, if necessary, a fine kneading step. Tea making and drying machines such as a rough rubbing machine and a middle rubbing machine used in the rough rubbing process or the middle rubbing process are configured for drying tea leaves and twisting the tea leaves into a predetermined shape. It has a fixed drum made up of a circular kneading drum and an upper diffusion drum, a rotating shaft rotatably provided in the fixed drum, a massaging hand and leaves attached to the rotating shaft. The rotating shaft is driven by a motor via a gear box, and hot air is introduced into the fixed body from a hot air generator. Tea leaves are twisted between the kneading drum and the kneading drum by a kneading hand provided on the rotating shaft, and when the tea leaves are diffused by hot leaves, moisture is deprived by hot air (for example, Patent Document 1).

[0004]
[Problems to be solved by the invention]
For example, in a conventional rough rubbing machine, a pair of rubbing hands and leaves are twisted in the same rotation trajectory on the rotation shaft. On the rotation axis, a pair of massaging hands and leaves are similarly provided adjacent to each other with a phase difference of 180 °. These massaging hands precede the leaves by 90 ° to 120 ° in the rotation direction. A large amount of tea leaves dropped on the tag plate of the massaging drum are twisted by a massaging hand, and thereafter, the tea leaves are diffused by the leaves to remove moisture. When the tea leaves are put into the fixed barrel and the coarse kneading machine is started, a steady state is reached a while later, and the tea leaves are always twisted by a kneading hand in a constant stagnation state.
However, since the tea leaves are twisted not only between the tag plate and the massager but also between the tea leaves, it is difficult to produce thinly twisted tea leaves, which greatly affects the quality of the tea leaves of the final product .
[0005]
An object of the present invention is to solve the above-mentioned problem and to provide a kneading hand arrangement structure of a kneading dryer suitable for producing finely twisted tea leaves.
Another object of the present invention is to provide a kneading hand arrangement structure of a kneading dryer capable of changing a twist state of tea leaves according to a production environment such as humidity and temperature.
[0006]
[Means for Solving the Problems]
In view of the above, the present invention provides a fixed cylinder comprising a lower semicircular kneading cylinder and an upper diffusion cylinder, a longitudinally extending rotating shaft rotatably provided in the fixed cylinder, and attached to the rotating shaft. The problem has been solved by providing a rubbing hand and a leaf grinder, and providing a rubbing hand in a phase preceding and following the leaf grain in a tea leaf rubbing and drying machine in which tea leaves are twisted by the rubbing cylinder and the rubbing hand.
[0007]
When tea leaves are put into the fixed barrel and the rough rubbing machine is started, a steady state is reached after a while. In the kneader-dryer of the present invention, the amount of tea leaves staying near the bottom of the kneading drum varies depending on the phases of the first group of kneading hands, the second group of kneading hands, and the phase of the leaves.
When a massager who precedes the leaf grinder tries to twist the tea leaves between the grinder and the tea body, most of the tea leaves diffused due to the leaf grind stay at the bottom of the grinder. When a massager following the leaf grinder tries to twist the tea leaves with the rubbing drum, most of the tea leaves diffused by the leaf grind are not dropped on the rubbing drum.
As described above, finely twisted tea leaves can be produced by combining the process of twisting tea leaves with a large amount of staying and the process of twisting tea leaves with a small amount of staying.
[0008]
Further, in the present invention, a pair of massaging hands having the same rotation orbit is attached to the rotating shaft with a phase difference of substantially 180 °, so that the leaves are adjustable in phase on the rotating shaft. Is preferred.
By providing a pair of kneading hands on the opposite side of the rotation axis and providing one leaf between the kneading hands, the amount of tea leaves twisted by the kneading hands is significantly different between the preceding side and the succeeding side. By providing the massaging hands at 180 ° intervals, the influence of the diffusion of the massaging hands is reduced. Many tea leaves stay in the rubbing hands on the leading side of the leafy leaves, and many tea leaves do not stay in the rubbing hands on the trailing side of the leaves. By twisting tea leaves in this state, finer twisted tea leaves can be produced.
[0009]
Further, in the present invention, at least one of the preceding massaging hand and the following massaging hand is detachable from the rotary shaft.
In this way, a group of massaging hands can be added as necessary according to natural conditions such as temperature and humidity and the amount of tea leaves processed.
[0010]
Further, the number of subsequent kneading hands from the leaves may be smaller than the number of kneading hands preceding from the leaves.
When the subsequent kneader twists the tea leaves with the kneading machine from the leaves, many of the tea leaves diffused by the leaves are not dropped on the kneading machine. Therefore, it is preferable to adjust the number of massaging hands according to the amount of tea leaves staying. In the present invention, the twisting process suitable for the amount of staying tea leaves is performed by reducing the number of kneading hands on the subsequent side having a small amount of staying.
[0011]
