Abstract

PROBLEM TO BE SOLVED: To provide a vibratory sieving machine for tea manufactures, preventing clogging of tea leaves and therefore capable of surely separating the tea leaves. SOLUTION: This vibratory sieving machine for tea manufacture is so contrived as to apply vibration to the tea leaves on a screen and sieve them, wherein holes for sieving are formed on a plate-like sieving screen in such a manner that each of the holes is downward perforated to become a opening having a bell mouth-shaped curve on its periphery.

2. Description of the Related Art Tea leaves obtained by steaming and kneading and drying green tea leaves are:
In addition to tea leaves that are suitable for ordinary products, hair leaves and powder are included. Also, there are various sizes of tea leaves as products, and tea leaves are conventionally classified into several types according to the size. As a device used at that time, there is a vibrating type or a rotary type sieve. The present invention relates to a vibrating sieving machine, which vibrates and conveys tea leaves on a screen while dropping tea leaves having a shape smaller than the opening provided on the screen, and leaving tea leaves having a larger shape on the screen. Is divided. As the screen of the conventional tea vibrating sieve, a screen made of a wire mesh or a sheet obtained by punching a plurality of simple holes in a steel plate has been used. Further, the upper part of the tea leaves passing position was left open, and no cover or the like was provided.

The conventional screen made of wire mesh is made of plain weave wire, and has the advantage that tea leaves are easily applied and easily come off due to the unevenness of the cross section due to the linear shape. There was a problem that tea leaves and stems were caught in the corners of the clogs and clogged. Also, a screen in which a mere hole is punched out of a steel plate has a problem that tea leaves and stems are hard to be caught and clogging is difficult, but because the cross section is flat, the tea leaves are hard to be applied and hard to come off. In any case, there is a problem that the tea leaves are almost flat on the screen, and the tea leaves can freely turn in various directions, overlap, and hardly come off. An object of the present invention is to provide a tea vibrating sieving machine which is hardly clogged and can be sorted properly.

Embodiments of the present invention will be described with reference to the drawings. A screen frame 3 having a screen 2 stretched thereon is installed on a vibrating frame 1, and is fixed substantially integrally by a screen frame presser 9 and a clamp 8. The screen 2 is divided into a plurality of screens, and several kinds of screens are prepared according to the classification degree, and are appropriately replaced depending on the change in the properties of the tea leaves or the degree of finishing. The screen 2 is provided with an opening 21 having a bell mouth shape as shown in FIGS.
As shown in FIGS. 2 and 7, the processing is performed in a wavy shape with irregularities along the moving direction of the tea leaves.

The vibrating frame 1 is supported on the entire frame 16 by a vibrating arm 4 so as to be able to vibrate.
It is converted into a swinging motion by the crank rod 13 and the vibrating arm 4. Below the screen 2, a passing tea leaf collection chamber 5 is provided for collecting tea leaves that have passed through the openings 21 of the screen 2. The cover 10 is a plastic-based antistatic treatment and is a substantially transparent member that can be observed from the outside. The entrance opening cover 11, the screen 2, and the passing tea leaves are used to prevent foreign matter from entering and dust from scattering. It is provided above the tea leaf passing position such as the outlet 6 and the non-passing tea leaf outlet 7. The cover 10 can be freely opened and closed by a clamp 8.

While spreading from the conveyor 19 with the diffusion chute 18, the tea leaves hit the front wall of the inlet rising cover 11, spread appropriately in the width direction of the screen 2, and fall. The tea leaves on the screen 2 which have been processed into a wavy shape are aligned while swinging, move toward the discharge port, enter the bell mouth-shaped punched hole 21, and enter through the hole 21. The small tea leaves pass through, fall into the passing tea leaf collection chamber 5, move to the passing tea leaf outlet 6, and move to the next step. Tea leaves that do not pass through the opening 21 of the screen 2 are discharged outside the machine through the non-passing tea leaf discharge port 7 and are moved to the next step.

According to the present invention, the tea leaves are guided to the opening by the bell-mouth-like punching (burring) of the screen, so that the classification can be performed effectively. Less damage to tea leaves moving on the screen. By processing the screen into a corrugated shape, the vertically elongated tea leaves are aligned in the moving direction, so that the classification can be performed efficiently.
In addition, since there is an opening so as to surround the tea leaves at the height of the wavy irregularities, classification can be performed even if the tea leaves overlap. By providing a substantially transparent cover on the upper part where the tea leaves move, foreign substances can be prevented from being mixed and dust can be scattered, and the state of the tea leaves can be observed from the outside. It is a place where static electricity is likely to be generated, and by performing antistatic treatment, it is possible to prevent the formation of tea powder.
