Raw tea leaves picked from tea gardens are put into a steamer and heated to approx.
When steamed with steam at 100℃, the volatile components in the leaves ooze out onto the surface of the leaves, making them sticky. This viscosity coefficient is unknown,
Although there are differences depending on the variety of raw leaves, they are so sticky that when squeezed in the palm of the hand, they stick together and form a clump.

Therefore, if steamed leaves in such a state are directly transported to the next rough rolling process, the tea leaves will stick to each other and form clumps, making it impossible to roll them well, resulting in lower quality and longer processing time. This results in inefficiency and additionally increases fuel consumption.

However, among these, those equipped with a raking device end up holding the steamed leaves against the net conveyor even temporarily when raking them while scattering them with the raking tool, and this causes problems with the purpose. This results in clogging of the wire mesh, which impairs the cooling effect and degrades quality.

In addition, the method that blows out pressure air from a fan simply blows only the surface of the leaf, or a similar operation, so it has the disadvantage that it cannot cool the entire front and back of the leaf or remove adhering moisture sufficiently. There is. This drawback was caused by the viscosity of the leaves, which clogged the wire mesh conveyor and blocked the ventilation, resulting in a decrease in cooling capacity and quality. The present application is newly devised from these current circumstances.

The scattering device 6 has the structure shown in FIG.
is a rotating drum whose circumferential surface is made of wire gauze C via support rings A and B, and which is coated with non-adhesive paint, and is removable as will be described later. Reference numeral 62 denotes a shaft that passes through the drum and loosely fits into the supporting rings A and B, and is attached to the side plate 5 of the scattering chamber.
It is supported by bearings 63 and 64 fixedly attached to the bearings 1 and 51. A sprocket 65 is attached to the bearing 64 side, and the drum 61 rotates by taking over power from the sprocket 37 shaft. 66 is an engagement plate that rotates together with the sprocket 65, and the engagement protrusions 67, 67 provided on this plate correspond to the engagement holes bored in the support ring B of the drum.
When the drum 61 rotates by inserting it into the holes B' and B', the protrusions 67 and 67 engage with the engagement holes B' and B' and rotate together, but when the drum is pulled out, the engagement holes B' , B', the protrusions 67, 67 can be extracted from them. Therefore, the above-mentioned bearing 64
is fixed to the side plate 51 with bolts and cannot be removed, but the bearing 63 is fixed with wing nuts 68, 6.
Since it is secured with screws 8, by loosening these, the bearing 63 can be removed and the rotating drum 61 can be taken out.

Then, if you turn on the power and turn on the switch (not shown), the net conveyor 2 will connect to each sprocket 3.
. Further, the fans 7 and 15 are rotated by the drive of the motor 16, and the cold air or hot air from the fan 7 flows into the scattering chamber 5, and most of it flows into the rotating drum 6.
In addition to ventilating through the net conveyor 2 and partially through the wire meshes 52 and 53, air is vented and exhausted. Further, the cold air from the fan 15 flows into the wind barrel 12, is rectified by the rectifier plate 14, and is blown onto the net conveyor 2 on the machine frame e for ventilation, and a portion is exhausted from the exhaust port 13.

Next, when the steamed leaves are delivered from the steamer 19 in the previous step, they are placed on the net conveyor 2 from the hopper 20 and fall into the scattering chamber 5 from the delivery end on the sprocket 35. At this time, since cold air or hot air from the fan 7 is flowing into the chamber, the steamed leaves are scattered and most of them are blown onto the rotating drum 61, and the steamed leaves are brushed off while the drum rotates. Some of the leaves fall directly onto the conveyor and are transferred in the same way.
2, it is further cooled by the cold air from the fan 15, and eventually falls from the delivery end 23 and is transported to the next process machine (not shown).

In the present application, as in the above structure, an air permeable scattering chamber 5 is provided in the middle where the long net conveyor 2 circulates,
As the steamed leaves fall into the chamber, cold air is blown from the fan 7, so the steamed leaves dance wildly in the chamber and are cooled down, and most of the moisture adhering to the steamed leaves is removed and oozes out to the surface. The added viscosity has a cooling effect that causes it to stick.

In addition, since an air-permeable rotating drum 61 is provided in the scattering room 5, the steamed leaves that are blown away by the cold air are brushed off by the rotation while coming into contact with the drum, and during this time, the constantly flowing cold air blows away the steamed leaves. Every single steamed leaf is exposed to the cold air, increasing its cooling effect.

さらに、散乱室に連接して風胴12を設け、フ

By the way, the wire mesh of the conventional cooling device mentioned above is the cause of clogging and inhibiting the cooling effect.
Among the steamed leaves, when plucking the original leaves, and this is unavoidable, some leaves and stems have been cut into small pieces, and some have been cut off from old stems.
Alternatively, there are miscellaneous materials, dust, etc. that get mixed in during plucking, and these, together with the above-mentioned attached moisture and viscosity, block the conveyor.

However, in the present application, a scattering device 6 is provided in the scattering chamber 5, and the steamed leaves falling into the chamber are made to collide with the rotating drum 61 using cold air from the fan 7, so that most of the steamed leaves that cause the clogging are removed. Since the rotating drum receives the irradiation, there is almost no clogging of the conveyor during circulation.

Therefore, although a non-adhesive paint is applied to the wire gauze C portion of the rotating drum, the steamed leaves may adhere to it and cause clogging, or it may pass through the wire gauze and sneak into the drum. It will accumulate. However, as this drum can be easily removed as mentioned above, it can be replaced with a new one or washed between tea making processes, reducing clogging of the circulating net conveyor. Air permeability is ensured, and the steamed leaves are always cooled in the best possible conditions, making it possible to obtain high-quality tea.

Furthermore, since the hot air generator 10 is provided and is made to flow into the suction port of the fan 7, when the moisture or viscosity of the steamed leaves is large, hot air can be sent in instead of cold air, and the tea leaves can be heated. It has the effect of being able to blow cold air according to the quality of the product, etc.
