Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a four-section type tea making machine that processes a predetermined amount of tea leaves per cycle, and improves the flow of hot air in the barrel to reduce the amount of hot air against the tea leaves. The purpose of this is to improve the quality of the tea product by improving the aeration of the tea.

A typical tea making machine with a rotary body is a medium rolling machine, which produces tea of Q1 or smaller. The − side of (b) is constructed with an iron plate (c) that is slidably fitted inside one end of the cylindrical moon β and fixed to the machine frame (a). A tea and confectionery inlet (2) is installed at the top, a hot air supply port (E) is installed at the bottom, an input chute (2), and a hot air generator (1) are installed at the bottom. A wire mesh (J) is stretched over the side surface of the other end of (B), and an exhaust pipe equipped with an exhaust vane is provided so as to cover the wire mesh (TE) surface. In the medium kneading machine, the hot air supply port (E) is inserted first, and hot air with a relatively fast flow rate and high temperature [ioo to 15o'c] is supplied from this port (bo), and the flow of the air is indicated by the arrow. As shown in T, the hot air spreads evenly within the cylindrical body (B). Therefore, in other parts, the ventilation of the hot air against the tea leaves is poor and the tea confectionery is damaged.Secondly, In order to maintain the temperature of the tea leaves at 35-40'Ct, use the hot air supply port (
e) The temperature of the hot air passing through T is 100 to 150 as described above.
The tea leaves around the hot air supply port (E) in the λ cylinder body (B) are exposed to high temperature and strong hot air, and the color of the tea leaves becomes reddish-black. The internal pressure inside the cylinder (b) increases, and the gap in the cylindrical cylinder (b) increases.
For example, the hot air leaks from the sliding part between the cylindrical body (B) and the casting or plate (C)] and the tea scoop flies out with it, making the environment worse, so the exhaust vane cannot be removed. Furthermore, it is not possible to increase the amount of hot air to increase the drying speed of tea confections. Fourthly, the hot air inside the cylindrical body (b) may be strongly sucked and exhausted by the exhaust vane (b), but even the hot air that still has enough drying power is exhausted. The efficiency of the hot air action is low, and it is necessary to supply more hot air than necessary for drying the tea and sweets.

After this research, problems 1 to 4 were solved by constructing almost the entire head panel (c) with a ventilation hole such as a wire mesh and using the entire head panel as a hot air supply port. The purpose of this project is to provide a rotating body tea making machine that simultaneously improves the quality of tea.

Embodiments of this invention will be explained based on the drawings. (1) is the machine frame, (2) is a cylindrical body with bamboo ducts lined inside and hung on the machine frame (1) in a rotatable manner, (3) is a cylinder + l1al

In the center of the cylindrical body (2), a double rotating support (4) is horizontally suspended and rotates in the same direction. (6) is a rolling wheel attached to the temporary frame (1). The cylindrical body (7) on which one end of the cylindrical body (2) is rotatably placed is an open cylindrical body] (2)
One end side surface (This is a head plate fitted into the sliding groove, and substantially the entire surface of the head plate (7) excluding the sliding part, the frame, and the tea and snack inlet (8) is made of wire mesh (13). (9) is a hot air supply air connected to the hot air generator (CLO) and arranged on one end side of the cylindrical body (2).
2) A sealing member (11) that slides on the one end (1) is attached to the supply cylinder (9) around the one end (2'), which includes the sliding part at one end and prevents hot air from flowing. is designed to prevent it from leaking outside the machine. I firmly believe in fruit (7). (12) is a tea leaf official chute that penetrates the supply cylinder (9) and leads to the tea confectionery intake port (8), and this chute (L2) is connected to the tea leaf input conveyor (20) and is connected to the tea leaf input port (8). ) is equipped with a damper (21) that opens and closes. The position of the tea leaf inlet (8) on the end plate (7) is preferably in the center so that the spread of hot air does not disturb Qt, but the position shown in Fig. 2.3 may be used.

(↓4) is the other end side of the cylindrical body (2) (it is a stretched wire mesh, the mesh is 8 meshes θ3 on the air supply side), and there are small pieces of tea leaves! ! A perforated plate that can cure a large number of small holes is sufficient. '(+5) is the cylindrical body (2
) is an exhaust pipe that covers the exhaust extension part (15). (17) is a cross flange that connects and fixes the cylinder shaft (3) to the other end of the cylinder body (2).

Chir2 The above hot air generation table 12 (1,0) is the air blast * (
18) The air blown in is directly or indirectly added to the combustion flame f of the burner (19) to generate hot air. (23) Circumference of cylindrical body (2) 1. + J] is a take-out door that can be opened and closed to prevent hot air from leaking when sealed. ) from Chaka Official Shiko 1-
The hot air that is forced into the cylindrical body 1 (2) via (2) and from the hot air generator (1o) on the other hand first spreads in the supply cylinder (9) and becomes almost evenly pressured. , mirror plate (
7) is evenly vented and supplied into the cylindrical shell (2). (2), the tea leaves rotate and spread within the cylindrical body (2) as shown in Fig. 4, so that the hot air comes into contact with the tea leaves without leaking and acts on them.Therefore, the hot air efficiently provides energy to the tea confectionery. It is highly effective.Also, the tea leaves come in good contact with the hot air inside the cylinder (2) and there is good ventilation, so the temperature of the hot air supplied is between 80°C and 80°C.
'C is sufficient, and since there is no high temperature around the hot air supply opening as in the conventional case, the tea confectionery will not get steamy and will retain its bright green color without developing a burnt aroma. is improved.

The hot air (exhaust air) that has reached the other end of the cylindrical body (2) is pushed by the hot air newly supplied to the T through the supply cylinder (9), ventilates the wire mesh (14), and passes through the exhaust extension cylinder. (15) to the exhaust pipe (1G), and is further discharged to the dust collector or outside the machine.
From the flow of hot air, the inside of the feed cylinder (9), including the sliding part between the head plate (7) and one end of the cylindrical body (2), is compared to the inside of the cylinder (2). The wind pressure is high, and by removing the conventionally installed exhaust vanes, the inside of the cylindrical body (2) is slightly pressurized (5), and hot air does not flow back from the sliding part and the tea scoop does not get clogged, which is necessary in the past. It is possible to remove the exhaust vane, which makes the exhaust system cheaper in the area. In addition, the cylindrical body (2
) The exhaust inside the inside is forcibly turned on (this is sealed except for the case where no suction is installed, so it does not affect the flow of hot air and prevents the hot air from dissipating). .

The tea leaves are kneaded and twisted by the kneading hands (5), and then transferred to the cylindrical body (2).
) and dried with hot air. When the moisture content on a dry weight basis reaches about 35%, open the take-out door (
23) Open and take out the tea confectionery and send it to the next process 9 Ma T
.

As described above, in this invention, hot air is supplied evenly into the cylindrical body (2) through the part m (13) that occupies almost the whole of the end plate (7), so that the hot air is distributed evenly to the tea and sweets. The efficiency of the hot air action is high and no energy saving is required, making the device inexpensive in the area.

Furthermore, in this invention, there is no problem even if the wind pressure inside the cylindrical body (2) is increased, so a large amount of hot air can be supplied into the cylindrical body (2).
It is also possible to use a medium rolling machine. In addition, it is also suitable for a single-rotation T-section type turret beach that requires a large amount of hot air.
