DETAILED DESCRIPTION OF THE INVENTION

[0019] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. The leaf vegetable device of this embodiment is applied to a scattered tea cooling device installed on a tencha production line, and as shown in Figure 1, is attached to a conveying means 5 for conveying tea leaves to a drying device 6 (tencha furnace), and the tea leaves (steamed leaves) are allowed to fall (nature fall) onto the conveying body D of the conveying means 5, thereby cooling and scattering the tea leaves into a substantially uniform state. In other words, the steamed leaves immediately after steaming in the previous process are at a high temperature, and if these tea leaves are conveyed to the drying device 6 in a hot state, they will deteriorate due to the residual heat. Therefore, the scattered tea cooling device blows the steamed leaves upwards, thereby cooling and drying them and preventing deterioration due to the residual heat.

[0020] The drying device 6 obtains tencha by transporting and drying the steamed leaves, whose enzymes have been deactivated after the steaming process in a steamer, and is equipped with a transport body D on which the tea leaves can be placed and transported. The transport body D is made of an endless member suspended across the transport means 5 and the drying device 6, and is capable of transporting the tea leaves in the transport direction. In other words, the tea leaves supplied in a stacked state to the transport body D in the transport means 5 are transported to the drying device 6, and then dried in the process of being transported inside the drying device 6. In the figure, the symbol F indicates a platform that supports the tea leaf transport parts in the transport means 5 and the drying device 6.

[0021] The scattered tea cooling device of this embodiment allows tea leaves to fall (naturally fall) onto the conveying body D of the conveying means 5, and then supplies them to the drying device 6 for drying.As shown in Figures 1 to 3, it is configured to include a main body 1 (scattered tea frame) extending upward from a predetermined position on the conveying means 5, a ceiling portion 2 formed at the top of the main body 1, an input portion 3 formed at a predetermined position on the side of the main body 1, a blower 4 (blowing portion) (air blowing portion), and a connection portion T connected to the blower 4 via a connection member H.

[0022] The main body 1 has a space S formed inside, which is separated from the surrounding area by a breathable mesh member, allowing the tea leaves to be blown up and fall onto the conveyor belt D, and an input part 3 and a connection part T are attached at predetermined positions on the front side. Specifically, as shown in Figures 2 and 3, the main body 1 extends above the conveyor body D of the conveying means 5, and the sides are separated from the surrounding area by a mesh member, and the bottom is open to the conveyor body D.

[0023] The input unit 3 is made of a hopper-shaped member that inputs tea leaves into the internal space S of the main body 1, and is attached to the main body 1 at a position above the connection part T. In other words, the tea leaves input from the input unit 3 reach the inside of the main body 1 and are blown upward by the air sent from the blower 4. Note that the input unit 3 is not limited to a hopper-shaped member as in this embodiment, and may be an opening through which tea leaves can be input into the main body 1.

[0024] The blower 4 (air blowing means) as the blowing section of the present invention is capable of blowing air into the main body 1 to blow the tea leaves dropped into the drop section 3 up towards the top surface 2a of the ceiling 2, and is fixed to a position below the main body 1 as shown in Figures 1 and 2. The blower 4 is formed with an intake port for drawing in air from the outside and an outlet port for blowing out the air drawn in by the intake port, and a connecting member H such as a hose is connected to the outlet port.

[0025] As shown in Figure 2, the connection part T is formed below the input part 3 formed on the main body part 1, and is connected to the blower 4 via a connection member H. The connection part T in this embodiment has a receiving surface that receives the tea leaves input from the input part 3, and is capable of blowing the tea leaves received on the receiving surface upward with the air sent from the blower 4.

[0026] Here, the ceiling part 2 of the scattered tea cooling device according to this embodiment is made of a member made of iron, stainless steel or the like attached to the top of the main body part 1, and the top surface 2a faces the space S of the main body part 1 so as to be able to receive the air blown from the blower 4. As shown in Figures 4 and 5, the top surface 2a of the ceiling part 2 is an arc-shaped curved surface (R-shaped) that protrudes upward (convex upward), so that the air blowing upward in the space S of the main body part 1 flows along the arc and smoothly changes direction downward.

[0027] As a result, the tea leaves (steamed leaves) put in from the putting section 3 are blown upward by the air blown from the blower 4, reach the top surface 2a of the ceiling section 2, and move along the arc of the top surface 2a before smoothly changing direction and falling downward, thereby preventing the blown tea leaves from sticking to the top surface 2a. Note that the top surface 2a in this embodiment is an arc-shaped curved surface that is in the direction of travel of the tea leaves (air blowing direction), but it may also be an arc-shaped curved surface in a direction perpendicular to the travel direction (air blowing direction).

[0028] Furthermore, in this embodiment, the top surface 2a is a smoothly curved surface, but as shown in Figures 6 and 7, the curved surface constituting the top surface 2a may be given an uneven shape. Note that Figure 6 shows the top surface 2a having an embossment a formed thereon, and Figure 7 shows the top surface 2a having a lattice-like groove b formed thereon. By forming an uneven shape on the top surface 2a of the ceiling portion 2 in this way, the contact area between the top surface 2a and the tea leaves can be reduced, and the tea leaves can be more reliably prevented from sticking to the ceiling portion 2.

[0029] Furthermore, the top surface 2a of the ceiling part 2 according to this embodiment is made of a material that is not permeable to wind and allows wind to flow along its arc-shaped curved surface (such as a pressed metal material such as iron or stainless steel, or a molded resin material). This allows the tea leaves blown upward to smoothly change direction downward without reducing the force of the wind on the top surface 2a, and more reliably prevents the tea leaves from sticking to the ceiling part 2a.

[0030] On the other hand, instead of the top surface 2a of the ceiling part 2 according to this embodiment, the top surface 2a of the ceiling part 2 may be made of perforated metal or a mesh material that allows wind to pass through. In this case, the wind can escape to the outside as it flows along the top surface 2a of the ceiling part 2, reducing the adhesion force of the tea leaves to the top surface 2a, and more reliably preventing the tea leaves from sticking to the ceiling part 2.

[0031] While the present embodiment has been described above, the present invention is not limited to this. For example, as shown in Figures 8 and 9, the ceiling 2 may be made of a hemispherical member, with the top surface 2a being a spherical curved surface that protrudes upward. In this case, regardless of the direction or position of the air blown from the blower 4, the tea leaves blown upward can be smoothly redirected downward along the curved surface, preventing them from sticking to the ceiling 2. In this way, the top surface 2a of the ceiling 2 can be a curved surface that has a curvature in one direction as in the above embodiment, or a spherical curved surface, and the top surface 2a of the ceiling 2 can be selected depending on the shape of the main body 1, the air blowing state, etc.

[0032] Note that other types of air blowing means may be used instead of the blower 4, and multiple air blowing means may be arranged in the width direction of the conveying body D. Furthermore, the main body 1 according to this embodiment is configured with a frame to which a mesh member is fixed, but the mesh may be suspended from the frame, or may be suspended from the ceiling of a building such as a factory, or multiple main bodies 1 may be connected and installed. Furthermore, in this embodiment, the device is applied to transporting tea leaves to a drying device 6 (tencha furnace) installed on a tencha production line, but it may also be applied to other drying devices, and may blow other tea leaves upward and drop them instead of tencha.

[0033] Furthermore, the present invention is not limited to a tea scattering cooling device, but can also be applied to a leafy vegetable device that grinds tea leaves or other leafy vegetables to produce tea powder. In this case, for example, as shown in Figure 10, the device may include a main body 1 having a space S formed therein for blowing up and dropping leafy vegetables (leaves), a ceiling 2 formed above the main body 1 and having a top surface 2a facing the space S within the main body 1, and a blowing-up section 7 that can blow up leafy vegetables put into the main body 1 toward the top surface 2a of the ceiling 2, and the top surface 2a of the ceiling 2 may be an arc-shaped curved surface that protrudes upward.

[0034] Specifically, the leafy vegetable device according to this embodiment crushes leafy vegetables into fine particles, and the blow-up unit 7 is made up of crushing blades attached to a drive shaft Ma that rotates when driven by a motor M. The blow-up unit 7 is made up of crushing blades that have horizontal and vertical blades, and when the motor M is driven to rotate, leafy vegetables fed into the main body 1 are blown upward while being crushed into fine particles. Note that the symbol h in FIG. 10 indicates the wiring of the motor M.

[0035] In this embodiment, as in the above embodiment, the top surface 2a of the ceiling portion 2 is an arc-shaped curved surface that protrudes upward. Therefore, leafy matter blown upward moves along the arc-shaped curved surface of the top surface 2a, smoothly changes direction, and falls downward, preventing the blown leafy matter from sticking to the top surface 2a and impeding the pulverization. This prevention effect is particularly significant when the leafy matter contains a lot of moisture and is viscous. Therefore, according to this embodiment, as in the above embodiment, it is possible to prevent the blown leafy matter from sticking to the top surface 2a. Note that the applicable leafy matter may be other leafy matter such as barley or mulberry, in addition to tea leaves. [Industrial Applicability]

[0036] As long as the device blows leaves upward and drops them, it can be applied to devices with different external shapes or devices with additional functions. [Explanation of symbols]
