Description

Detailed Description of the Invention This invention steams raw tea leaves placed in a fixed steaming barrel using superheated steam to evaporate the water deposited on the tea confectionery, and also allows the high-temperature superheated steam to sufficiently penetrate into the tea leaves to evenly steam the tea leaves. Fixing of a machine frame 3 equipped with a steamer configured by having a fixed steaming barrel 1 on one side and communicating with a rotary steaming barrel 2 on the other side for the purpose of effective steaming. Steaming body 1
A rotary shaft 5 with a plurality of stirring hands 4, 4, . are communicated,
By the superheated steam blown in by the blowing pipe 6,
Initial steaming is performed on the raw tea leaves that are introduced from the input lower provided on the upper side of the fixed steaming barrel 1, and the initial steamed tea leaves are
This is an improvement of a tea leaf steaming machine in which the tea leaves are stirred by the rotation of the stirring hands 4, 4, . Inside the fixed steaming barrel 1, there are a plurality of curved steam introducing tools 8, 8, . . . on the periphery.
. . . , a steam introduction cylinder 10 fixedly installed in a substantially linear shape N across the steam introduction roads 9, 9 . . . is rotatably installed across the introduction body cavity 11 The tea leaves are initially steamed in the steam introduction cylinder 10 by the steam introduced through the steam introduction roads 9, 9, . . . of the steam introduction cylinder 10. As an embodiment thereof, a dexterity 14 rotatably supported on both side edges 12, 13 &ζ machine frame 3 of the steam introduction cylinder 10 is provided.
．． The steam introduction cylinder 10 is rotated by the rotational drive of one of the steamers 14, and one side edge 16 of the rotary steaming cylinder 2 is rotatably supported by the machine frame 3, The curved hot air introduction blade 8 is fixed to the other dexterity 15.
, 8..., a large number of uneven folds 17, 17.
. bearing 19
19, and is rotated by a drive motor 20.

In the drawing, 21 is the wire mesh of the rotary steaming cylinder 2, 22 is the rotational drive motor of the steam introduction cylinder 10, 23 is its rotation transmitter, 24 is the rotational drive mechanism of the rotary steaming cylinder 100, and 25 and 25 are the rolls. .

In conventional tea leaf steaming machines, the steaming action is generally performed using high-temperature raw steam, so during the steaming process, the moisture adhering to the surface of the tea confectionery causes the high-temperature steam to enter the tea confectionery. There is a drawback that the steaming operation cannot be carried out effectively due to impediment of penetration.

In order to eliminate this drawback, in the tea leaf steaming machine devised in advance Utility Application No. 57-72801, one side,
A fixed steaming barrel is provided in the steamer, and a rotary steaming barrel is connected to the fixed steaming barrel to form a handling barrel, and a rotary shaft with a plurality of stirring hands protrudes through the handling barrel. established,
In addition, steam is fed into the fixed steaming barrel, and the steam steams the raw tea leaves introduced through the inlet, and the rotation of the stirring hand causes the rotary steaming barrel to steam. A plurality of small-diameter holes are bored in the peripheral wall of the fixed steaming drum, and the outer mantle surrounds the peripheral wall of the fixed steaming drum, and the outer shell is overlapped and steamed. A body cavity communicating with the through hole is formed in the outer shell, and a blowing pipe for superheated steam superheated by a heating furnace is communicated with the body cavity to introduce superheated steam. , it has been developed to perform an initial steaming action.

However, with this structure, the introduction of superheated steam into the fixed steaming barrel is insufficient, and there is a risk that the initial steaming action of the tea leaves will not be fully performed.

On the other hand, the invention of this application makes the initial steaming action in this prior invention equally effective.According to the invention of this application, there is a As appropriate, a steam introduction cylinder 10 having a plurality of curved steam introduction tools 8, 8, . The steam introduction cylinder 1 is installed rotatably across the introduction body cavity 11.
Since the tea leaves are initially steamed in the steam introduction cylinder 10 by the steam introduced through the steam introduction roads 9, 9, . . . , the superheated steam is As the steam introduction cylinder rotates, the raw tea leaves are guided by the curved steam introduction tool, pass through the steam introduction road, and are sucked into the steam introduction cylinder in a tangential manner. Stirring is extremely useful as it evaporates the water adhering to the raw tea leaves and provides an evenly effective steaming effect.
