Description

[Detailed description of the invention] This invention relates to a floor-standing air permeable duct for humidification, ventilation, etc. that is connected to a humidification device in order to prevent green tea leaves from wilting during the tea manufacturing and storage process. It is something.

Conventionally, these floor-standing air permeable ducts generally have a fourth
It was an air permeable duct with a generally box-shaped front view as shown in the figure. For this reason, for example, humid air is blown out only to the left and right and upward, and if green tea leaves are piled up in that direction as shown in A of the same figure, this air will circulate between the green tea leaves. , it becomes possible to apply moisture almost uniformly to fresh tea leaves, and sufficient results can be expected in preventing withering. However, even in this case, the water is not sprayed to the corners of the box shape, and moisture is not sufficiently applied to the corners. Furthermore, as shown in Figure B, when the tea leaves are not piled up in an orderly manner in the direction in which the humid air is ejected (which is usually the case), the constant direction of the ejection causes the humid air to flow between the tea leaves. The leaves are not evenly blown, and the heat of breathing and collected heat from the fresh tea leaves cannot be absorbed sufficiently, resulting in the so-called wilting phenomenon in which some parts of the tea leaves become too dry and cause symptoms of withering, and other parts become too wet, resulting in wet leaves. This has led to problems such as troubles occurring in subsequent processes, and even deterioration of quality. In particular, as mentioned above, if even the slightest symptoms of withering occur, the freshness of the fresh tea leaves (the taut state of the tea leaves) will be lost, and the fresh tea leaves will tend to stick together, causing the gaps to become smaller or disappear. Ventilation becomes difficult. As a result, the withering progressed further, often resulting in a serious situation where the entire deposited tea leaf layer became wilted.

In view of the above, it is an object of the present invention to provide an air permeable duct that allows humid air to be ejected in a wide variety of directions, and that allows more even ventilation by eliminating coarse accumulations in certain areas.

Hereinafter, one embodiment of the present invention will be specifically described based on the drawings.

Reference numeral 1 denotes a humidifier having an air vent 2 at the upper front side and an air outlet 3 at the lower rear side, and is equipped with a humidifier 4 such as an ultrasonic humidifier and a fan 5. 6 is a constricted trapezoidal frame when viewed from the front, and a square-shaped main body 6a.
and a rod-shaped foot portion 6b, preferably with a horizontal portion of the foot portion 6b protruding downward from the lower end edge of the main body portion 6a. This frame body 6 is erected at appropriate intervals, and the air permeable duct body has a large number of through holes 7 made of punched metal, mesh, etc., which have a constricted trapezoidal shape when viewed from the front and match the outer peripheral surface of the frame body 6. 8 will be provided. As a result, a stepped recess 9 is formed in the longitudinal direction of both inclined side surfaces 8a, 8a of the air permeable duct A. Then, one end of this air permeable duct A was connected to the air outlet 3 of the humidifying device 1, and several air permeable ducts A and A of the same configuration were connected to the other end. Fresh tea leaves are deposited on the air permeable ducts A, A, and A. In addition, depending on the case, air permeable duct A may be
Only one of them may be connected to the humidifying device 1. The air sucked through the air vent 2 of the humidifying device 1 is humidified by the humidifier 4 (however, the humidifier 4 is not operated when only air is being blown), and the air is humidified as shown by the arrow in Fig. 1. It circulates inside the device 1 and is fed to the air permeable duct A through the fan 5 and the air outlet 3 thereof. As shown in FIG. 3, the supplied humid air is ejected from the through holes 7 in both inclined side surfaces 8a, 8a, top plate surface 8b, etc. For example, both inclined side surfaces 8a, 8a
From there, in the horizontal direction, in the stepped recess 9, in the diagonal downward and horizontal directions, and in the top plate surface 8b, in the upward direction, the tea leaves are ejected in multiple directions and into the gaps between the accumulated tea leaves. Humid air, etc. can be ventilated almost evenly. This makes it possible to prevent the above-mentioned withering and the like. In particular, in the present invention, a rough accumulation of green tea leaves is formed around the periphery B of the stepped recess 9, and this is achieved toward the side surface where ventilation is difficult.
It is believed that the above-mentioned effects are even more possible. Furthermore, the frame body 6
Both sides 8 of the air permeable duct A are
If a gap C is formed at the bottom of a and 8a,
Moist air and the like are blown out from this gap C, which has the effect of allowing ventilation to the deposited floor surface area, thereby achieving uniform ventilation.

Since the present invention has the structure described in detail above,
This allows for substantially uniform ventilation of humid air into the gaps between the piled green tea leaves, which helps prevent wilting and wet leaves. In particular, in the present invention, since a stepped recess is provided, the above-mentioned effects can be further achieved, and it is thought that sufficient ventilation to the side surfaces can be achieved. Furthermore, if a gap is provided in the air permeable duct, ventilation can be allowed to flow to the floor surface portion and to the hem portion where the pile width is large. Furthermore, it allows ventilation in many directions, allowing sufficient absorption of the heat of breathing and collected heat from the green tea leaves.
