Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to removal of tea powder adhering to an exhaust wire mesh provided on a rotary drum of a tea making and kneading machine.

[0002]

2. Description of the Related Art In a tea making and kneading machine, a hot air blowing port is provided at one end of a rotary drum, hot air is supplied by a hot air generator, and tea leaves are dried by the hot air. Then, the exhaust fan is operated to exhaust air from the other end where the exhaust wire mesh is stretched. In this way, while applying hot air to the tea leaves inside the rotary drum, the rotation of the rotary drum and the main shafts around the kneading hands are each rotated, and the tea leaves are sandwiched between the drums and the kneading hands to form a shape. It is prepared and dried. The drive of the rotary cylinder and the drive of the main shaft with a claw are independent, and the main shaft rotates in the same direction at about twice the rotational speed of the rotary cylinder. Due to this difference in rotation speed, the tea leaves are rubbed efficiently. As described above, when the tea leaves are rubbed and dried by the tea making and kneading machine, a large amount of tea powder is generated, and the tea powder is sucked by the exhaust fan together with the exhaust gas.

A conventional exhaust wire mesh is stretched outside the body drive arm. Since the tea powder tries to pass through the exhaust wire mesh together with the exhaust gas, a fine wire mesh is used, and the tea powder adheres to the exhaust wire mesh. When the tea powder adheres to the exhaust wire mesh, it stagnates the exhaust and reduces the air flow,
This will reduce the drying efficiency and the quality of the product. Therefore, since it is necessary to keep the exhaust wire mesh clean, sometimes the rotation of the tea making and kneading machine is stopped, and an operator enters the rotary drum to clean the exhaust wire mesh with a cleaning tool such as a broom.

However, it is very difficult for an operator to enter and clean the inside of a narrow rotatable drum provided with a kneading hand, and avoid stopping the machine when it is busy and the machine is fully operating. That's a big deal. Therefore, in recent years, as a device for automatically performing work performed by an operator, a wire mesh cleaning brush is installed in a kneading hand closest to an exhaust part wire mesh, as in Japanese Utility Model Laid-Open No. 56-28688. The wire net is being dedusted.

[0005]

When the wire net cleaning brush is attached to the kneading hand closest to the exhaust wire net as in the conventional art, the wire net cleaning brush rotates in the tea leaves during the tea making process. , The wire mesh cleaning brush is bent, the wire mesh cleaning brush is pushed by the tea leaves, and the exhaust part wire mesh is bent, or the tea leaves are pressed against the exhaust part wire mesh and adhere so strongly that they cannot be easily removed. To do.
Further, since the exhaust wire mesh is stretched outside the cylinder drive arm, the wire mesh cleaning brush hits the cylinder drive arm, the noise is noisy, the brush part is easily broken, and the exhaust mesh cannot be cleaned cleanly.

[0006] Therefore, an object of the present invention is to provide a tea making-in-rubbing machine which can easily remove dust from the entire surface of the exhaust wire-meshing machine of the tea making-in-rubbing machine without breaking the wire-mesh-cleaning brush. .

[0007]

In order to achieve the above object, in a tea making and kneading machine having a rotating cylinder provided with an exhaust wire mesh,
The exhaust wire mesh is stretched inside the cylinder drive arm, and a brush for cleaning the wire mesh is installed on the main shaft between the exhaust wire mesh and the cylinder drive arm.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION When the tea making and kneading machine constructed as described above is started, the wire net cleaning brush removes the tea powder adhering to the entire surface of the exhaust part wire net.

An embodiment will be described with reference to the drawings. FIG. 1 is a front sectional view of a conventional tea making kneading machine provided with a wire net cleaning brush 14, FIG. 2 is a front sectional view of a tea making tea kneading machine of Example 1 provided with a wire net cleaning brush 5 of the present invention, and FIG. The wire mesh cleaning brush 5 and the wire mesh cleaning brush 1 of the kneading drying chamber 12 of the present invention
3 is a front sectional view of a tea making and kneading machine of Example 2 in which 3 is installed.

The first embodiment will be described with reference to FIG. The exhaust wire mesh 6 is stretched inside the trunk drive arm 2 and
The wire mesh cleaning brush 5 is installed on the main shaft between the and the body drive arm 2. The rotating cylinder 1 is rotated by the cylinder drive arm 2, and the kneading hands 3 rotate together with the main shaft 4 in the same direction at a rotation speed about twice that of the rotating cylinder 1. Since the exhaust wire mesh 6 is attached to the rotary cylinder 1, it rotates at the same speed as the rotary cylinder 1, and the wire mesh cleaning brush 5 attached to the main shaft 4 rotates at the same speed as the main shaft 4. A hot air blowing port 7 is provided at one end of the rotary drum 1,
Hot air 8 is supplied by a hot air generator (not shown), and the exhaust fan 9 is operated from the other end where the exhaust portion wire net 6 is stretched to exhaust the air. The tea leaves 10 are charged from the charging port 11 while the rotary drum 1, the main shaft 4 (rubbing hands 3, wire mesh cleaning brush 5) and the like are rotating. Hot air 8 is blown while sandwiching the tea leaves 10 between the rotary drum 1 and the rubbing hands 3 to dry them.

However, when the tea leaves 10 are dried while rubbing, the tea leaves 10 are likely to become powder, and this tea powder is sucked by the exhaust fan 9 together with the exhaust gas and tries to pass through the exhaust wire mesh 6, so that the tea powder is It adheres to the exhaust wire mesh 6. The tea powder is removed by the wire net cleaning brush 5. The removed tea powder returns to the kneading and drying chamber 12. The wire mesh cleaning brush 5 is rotating when the tea leaves 10 are in the kneading and drying chamber 12 and not, and the tea powder is removed without being affected by the tea leaves 10.

The wire mesh cleaning brush 5 of the present invention and the kneading and drying chamber 1
A second embodiment in which the second wire net cleaning brush 13 is provided will be described with reference to FIG. The wire mesh cleaning brush 13 of the kneading chamber 12 is attached to the main shaft 4. By making the wire net cleaning brush 13 smaller than the conventional wire net cleaning brush 14 and adjoining it, the wire net cleaning brush 13 does not hit the tea leaves 10 but removes the portion near the main shaft 4. Then, the portion far from the main shaft 4 is dedusted by the wire mesh cleaning brush 5. Therefore,
The entire surface of the exhaust part wire mesh 6 is powdered from both sides.

[0013]

Since the present invention is configured as described above, it has the following effects. By attaching a wire net cleaning brush to the outside of the exhaust wire net,
It is easy to remove because it is pushed out and removed in the direction where the tea powder adheres. In addition, since tea powder that has adhered to the wire mesh can be reliably removed during tea production without being affected by tea leaves, there is no reduction in the air volume, efficient drying is possible, and high quality products are manufactured. You can

Since the machine can be automatically cleaned during operation without stopping the machine and manually cleaning the exhaust wire mesh, it is safe and efficient. Further, since the exhaust wire mesh and the brush for cleaning the wire mesh are not destroyed, it is not necessary to replace the parts, which leads to cost reduction.

By installing the wire net cleaning brushes on both sides of the exhaust wire mesh as in the second embodiment, the entire surface of the exhaust wire mesh can be further cleaned from both sides. Further, the wire net cleaning brush in the kneading and drying chamber can be made smaller than the conventional wire net cleaning brush, and is not bent due to the influence of tea leaves.
