Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing broken green tea and a chopper device thereof.

Figure 1 shows the conventional green tea manufacturing process.
is a steamer, B is a roughing machine, C is a twisting machine, D is a hollowing machine, E is a smelting machine, and F is a drying machine.

To explain the process, the raw tea is passed through a heated steaming chamber through steam in the Swallow Machine A, rapidly cooled with an electric fan to remove dew, and then steamed in the same process in the Coating Machine B. After drying the raw tea and removing about half of the moisture,
This raw tea is heated at room temperature without applying heat to make up for the lack of roughness, and to even out the moisture content of the tea leaves.Then, the tea leaves are directly put into the Nakashi machine D and stirred while adding hot air. After removing excess water from the tea leaves, the tea leaves are heated and dried using a dryer E to shape the tea leaves, and then finished drying is performed using a dryer F until the moisture content of the tea leaves is 4% or less to complete green tea. However, when doing this, the color selection of the tea leaves is insufficient due to the insufficient kneading during the pseudo-twisting process, and in addition, powdered tea is likely to occur due to the forced shaping of the tea leaves using a seishin machine. In addition, there were defects such as loss of flavor. In view of this problem, the present invention, as shown in Fig. 2, eliminates the bare twisting and refinement steps, replaces the twisting step with the chopper device G of the present invention, and cuts the loosely found tea leaves while vigorously kneading them. The tea leaves are removed and dried through a dryer D and a dryer F to provide consumers with broken green tea with less powder and rich flavor and light blue color.

The chopper device G of the present invention will now be described with reference to the drawings.

In the figure, 1 is an L-shaped press-fit tube installed inside the frame 2, and its lateral inner wall surface is provided with spiral irregularities, and the press-fit tube 1
Inside is a pair of vertical and horizontal rope shafts 3 with spiral blades a on their circumferential surfaces.
4 is mounted on the shaft.

Reference numeral 5 designates a plate with a large number of through holes b.Several types of plates 5 with different sizes of through holes b are prepared, and an iron plate arbitrarily selected from among them is provided on the inner edge of the outlet end of the press-fit tube 1. Joint part c
It is fixed by being pressed by a plate retainer 6 which is screwed onto the outer periphery of the outlet end of the press-fit cylinder 1.

Further, a support hole d for supporting the shaft end of the horizontal lamp shaft 4 is bored in the center of the plate 5. 7 is a cutter, the cutting edge of which is placed opposite to the inner wall surface of the plate 5, and the square hole e provided in the center is inserted into the square columnar formation part b provided at the end of the horizontal azusa shaft 4. It is provided so as to rotate integrally with the horizontal sedimentation shaft 4.

Reference numeral 8 is a hawk plate with a radial protrusion 9 on the inner end surface, and the gap between the plate 5 and the hawk plate 8 is inserted into the proper position of the screw punch 9 screwed and fixed in the same axial direction to the end surface of the transverse shaft 4. Screw the stopper nut 10 to be adjusted, insert the rope plate 8 into the screw punch 9 with iron until the stopper nut 1 is firmly installed, and then attach the spring 11 to the screw punch 9, and tighten the spring 1 with the adjustment nut 12.
The elastic force of the stopper nut 8 is adjusted and the stopper plate 8 is crimped by one stopper nut.

Reference numeral 13 denotes a vibrating cage installed opposite to the green inlet end of the press-fitting tube 1, which vibrates finely back and forth by a vibrating pestle 15 linked to a motor 14 to transport the tea leaves introduced from the hopper 16 into the inlet of the press-fitting tube 1. It is set up to be sent.

The horizontal azusa shaft 4 is connected to a transmission 18 linked to a motor 17, and the vertical azusa shaft 3 is connected to a sprocket attached to the upper end of the vertical light azusa shaft 3 via a transmission shaft 19 linked to the transmission 18. 20 is attached to the upper end of the transmission shaft 19 and connected to a recessed sprocket 21 via a chain 22.

Since the chopper device G of the present invention is configured as described above, the tea leaves are steamed in the Aoi heating machine A, dried and ground in the coarsening machine B, and about half of the moisture has been removed, and then the tea leaves are transferred to the hopper 16. If you put the tea leaves inside, the tea leaves will be hopper 16.
Due to the back-and-forth vibration applied by the vibrating pestle 15 which gradually falls from the vibrating basket 13, the tea leaves that have fallen into the vibrating basket 13 are sent to the inlet of the press-fitting tube 1, where they are transported to the vertical fly rotating inside the press-fitting tube 1. The tea leaves that have entered the press-fit tube 1 by the Azusa shaft 3 are forced into the press-fit tube 3 where the Yokotaka Azusa Fuji 4 is rotating, where they are strongly kneaded and sent to the outlet of the press-fit tube 1 to make Yokotaka Azusa. The cutter 7 provided at the end of the shaft 4 cuts the sweets into small pieces and pushes them out through the hole b of the plate 5, and the tea cakes that have been pushed out of the hole b as a mass are cut into pieces by a cutter 7 provided on the outside of the plate 5. The tea leaves are separated and taken out by radial protrusions 9 provided on the inner end surface of the azalea shaft 8 that rotates together with the azalea shaft 4, and the tea leaves that are finely cut and taken out in this way are The green tea is put into the dryer D, where it is agitated with hot air to remove moisture, and then finished in the dryer F' for final drying to complete broken green tea. The broken green tea completed as described above contains very little powder compared to conventional products, and has excellent color selection, flavor, taste, light color, etc., and has an extremely good yield. The chopper device of the present invention has a very simple structure, and can produce good broken green tea by appropriately replacing the plates with holes of different sizes. Since the cutting function is greatly reduced, it can be used as a substitute for a milling machine, and it is also possible to use a conventional method of manufacturing with a refined process, which will have a great impact on the industrial world.
