Description
Technical field
The invention belongs to tea-processing equipment technical field, in particular to a kind of high efficiency tea screening device.
Background technique
It generally will do it the processes such as drying, screening after tea picking is complete, drying course is to remove the water in tealeaves
Point, have the characteristics that improve tealeaves fragrance, increase the tealeaves resting period, and screening is then the commodity value in order to improve tealeaves,
Tea leaf quality is set to standardize.Existing tea screening is usually that Tea screening machine is used to carry out, what is sieved to tealeaves
When, after tealeaves is placed on sieve plate, drive sieve plate to vibrate up and down using vibration device, the tea dust and tea stalk in tealeaves are from sieve
It is fallen in the sieve pore of plate, completes the screening to tea dust in tealeaves and tea stalk.And since existing Tea screening machine is all by vibrating
Device drives sieve plate vibration, is easy to cause to damage to rack, and if when tealeaves is deposited on oscillating screen plate, the efficiency of screening compared with
It is low, screening is easily caused not exclusively, and this screening machine needs artificial or other devices to send out the tealeaves on sieve plate, in discharging
Easily unsegregated tealeaves is mixed, influences to screen quality.
Chinese patent CN108636791A discloses a kind of tea screening device, including pedestal, bracket, sieve bucket, motor and
