A production method of faint scent white tea comprises the following steps:
s1, screening: quantitative tea leaves are placed in the screening barrel 1, the main shaft 5 is driven by the reciprocating motor 6 to drive the screening barrel 1 to rotate, the screening barrel 1 drives the tea leaves in the screening barrel to roll, the tea leaves leak along the filter screen 2, the tea leaves with unqualified sizes can be screened conveniently, meanwhile, the tea leaves slide along the main inclined plate 3 and the auxiliary inclined plate 4, the rolling stroke of the tea leaves in the screening barrel 1 can be prolonged, and the filter screen 2 can fully filter the tea leaves;
s2, spreading green: meanwhile, the fan 14 is turned on, air is blown into the screening barrel 1 through the filter screen 2 by the fan 14, the air forms airflow and takes away moisture on the tea leaves, and water stains on the tea leaves are conveniently removed until the tea leaves emit faint scent;
s3, fixation: the reciprocating motor 6 is controlled to stop, the sealing door 7 is opened again, tea leaves with fragrance are sent to the heating kettle 17, the heating kettle 17 and the tea leaves in the heating kettle 17 are heated through the heating pipe 18 in a specified time period, so that moisture in the tea leaves is evaporated in a high-temperature environment, tissues in the tea leaves are damaged, and fragrance molecules in the tea leaves are conveniently emitted to the air;
s4, arranging strips: when the heating pipe 18 works, air is conveyed into the air inlet pipe 23 and the bent pipe 27 through the fan 24, the spray head 28 sprays air flow, the spray head 28 drives the air inlet pipe 23 to rotate under the reaction of the air flow, so that the spray head 28 sprays air in the circumferential direction to stir tea leaves in the heating kettle 17, the tea leaves are convenient to turn over, and the tea leaves are uniformly heated in the heating kettle 17 until the tea leaves become fine and straight;
s5, primary baking: the tea leaves which are heated in the heating kettle 17 are laid at one end of the conveyor belt 29, the tea leaves are convenient to automatically transport along with the rotation of the conveyor belt 29 until the tea leaves move to the inner part of one end of the protective cover 31 and contact the irradiation area of the fluorescent lamp 32, so that the fluorescent lamp 32 dries the tea leaves to dry the tea leaves, and the tea leaves are convenient to store;
s6, cooling and moisture regaining: when the conveyor belt 29 drives the tea leaves to move to the position right below the atomizing nozzles 33, the water mist sprayed by the atomizing nozzles 33 partially falls on the tea leaves, so that the water is conveniently and uniformly distributed on the tea leaves, the tea leaves absorb the water and become soft, and cleaning molecules in the tea leaves are fully activated;
s7, re-baking: finally, the conveyor belt 29 carries the tea leaves to the inside of the other end of the shield 31 and contacts the irradiation area of the fluorescent lamp 32 again, so that the fluorescent lamp 32 dries the tea leaves again, the tea leaves can be sufficiently dried, the tea leaves can be conveniently dried and packaged, and the fragrant white tea can be produced.
The working principle is as follows: the during operation, put into screening bucket 1 with appropriate amount fresh tea, it rotates to drive screening bucket 1 through 5 rotations of reciprocating motor 6 drive main shaft, tealeaves constantly turns under screening bucket 1's drive, make tealeaves slide along main swash plate 3 and vice swash plate 4 wavy in screening bucket 1 is inside, with extension tealeaves at the stroke of screening bucket 1 inside, conveniently increase tealeaves and filter screen 2's area of contact, thereby moisture on the tealeaves volatilizees in the air from filter screen 2's space, so that spread green to tealeaves, impaired blade when can reducing tealeaves when spreading green, improve the effect that tealeaves spreads green.
When screening bucket 1 rotates, output intermittent type nature through pneumatic cylinder 10 promotes 8 lifts of base, base 8 drives the one end fluctuation of main shaft 5, make screening bucket 1 rock along with the fluctuation of main shaft 5, and supporting wheel 9 supports one side that pneumatic cylinder 10 was kept away from to base 8, can be around the rotatory certain angle of supporting wheel 9 when base 8 fluctuates, conveniently rock the tealeaves of screening bucket 1 inside, can shakeout the tealeaves on the filter screen 2, with reduce tealeaves because of piling up the barrier effect who causes when shakeout green to it.
When the mechanism during operation of blowing, partial gas in the air-supply line 23 flows to shower nozzle 28 along hard tube 26 and return bend 27, through the structural characteristic effect of return bend 27 along the circumference array distribution in the hard tube 26 outside, shower nozzle 28 and return bend 27 push hard tube 26 rotatory under the reaction of air current for 28 circumference blowout gas of shower nozzle blows to the inside tealeaves of heating kettle 17, conveniently evenly stir tealeaves, so that tealeaves is heated evenly, can improve the effect when tealeaves is fried and is managed with the reason strip.
When tea leaves are discharged from the blanking pipe 21, the tea leaves are received by the conveyor belt 29 and are separated by the partition plates 30, so that the tea leaves are uniformly spread outside the conveyor belt 29, automatic tea leaf conveying is facilitated until the conveyor belt 29 drives the tea leaves to move to one end of the shield 31 and be located in the irradiation area of the fluorescent lamp 32, the fluorescent lamp 32 dries the tea leaves, then the conveyor belt 29 drives the tea leaves to move to the spraying area of the atomizing nozzle 33, the atomizing nozzle 33 sprays water mist to cool the tea leaves, and finally the conveyor belt 29 drives the tea leaves to move to the other end of the shield 31 and be located in the irradiation area of the fluorescent lamp 32 again, so that the fluorescent lamp 32 dries the tea leaves again, the fragrance of the tea leaves is rich, and the quality of fragrant white tea products is improved conveniently.
