The invention discloses a kind of tea screening method, it is related to tea processing technical field, comprises the following steps：Six fort tea gross tea are subjected to horizontal vibration by charging device tea ribrating-sifting machine screen cloth face, screen cloth under the drive of motor, the tealeaves less than sieve screen apertures is transported to by tea-conveying device the tea inlet port of tealeaves circular screening machine；Tealeaves more than sieve screen apertures is transported to and cuts tea machine and carry out cutting tea secondary screening again；Tealeaves is sieved into tealeaves circular screening machine, and enters tea mouth from what first, second grade of screen cloth tea outlet was respectively delivered to tea winnower；Tealeaves after selection by winnowing enters tea mouth from what two tea outlets were transported to tea stalks picking-out machine；From two kinds of identity tea of tea winnower selection by winnowing, stalk-sorting operation is carried out into tea stalks picking-out machine, finally obtains the six positive tea of fort tea of two kinds of standards.The present invention can solve the problems, such as that six fort tea tea screening efficiency are low present in prior art, cost of labor is high.
Description
Technical field
The present invention relates to tea processing technical field, especially a kind of method for sieving suitable for tea processing.
Background technology
Tealeaves reaches certain classification standard in shape before dispatching from the factory, and need to enter pile fermentation, Steaming in six fort tea gross tea
Six fort tea gross tea are sieved before, and the six fort tea tealeaves that diameter, length are differed greatly make a distinction out, finally
To the net tea of each grade；Screening process of the current each Tea Production factory to tealeaves generally uses screening plant such as shaking screen machine, rotary strainer
Machine, winnowing machine and stalk pickup machine etc. are sieved, and these screening plants are individually to be screened, i.e., from the outlet of foreground equipment point
The tea elected need to be installed with storage facility, and the entrance for being then sent through next device carries out second of screening, and so on, these
Following weak point be present in the screening mode of tealeaves：First, artificial screening efficiency is low, and cost of labor remains high；2nd, quality is screened
Unstable, quality can not ensure；3rd, screening process human hand constantly touches tealeaves, tealeaves is polluted again.
The content of the invention
It is an object of the invention to provide a kind of tea screening method, this tea screening method can solve in the prior art
The problem of tea screening efficiency is low, cost of labor is high.
In order to solve the above problems, the technical solution adopted by the present invention is：
This tea screening method, comprises the following steps：
A, will through fixing, just rub, heap is vexed, rubs, dries again etc., and tealeaves gross tea made of series of process passes through charging device tea
Leaf trembles sieve machine screen face, and screen cloth carries out horizontal vibration under the drive of motor, and the tealeaves less than sieve screen apertures falls into and trembles sieve machine screen
Bottom, the tea inlet port of tealeaves circular screening machine is transported to by tea-conveying device；Tealeaves more than sieve screen apertures is transported to and cuts tea machine and enter
Row cuts tea secondary screening again；The screen cloth of the tea ribrating-sifting machine is 5 mesh, and vibration frequency is 300 ~ 400 revs/min, amplitude 5cm；
B, the tealeaves circular screening machine is provided with three-layer screen altogether, and first layer is 5 eye mesh screens, and the second layer is 14 eye mesh screens, third layer
For the screen cloth of 24 mesh, each layer screen cloth is respectively arranged with respective tea outlet, and compass screen surface tea is obtained from first order screen cloth tea outlet, from
What two level screen cloth tea outlet obtained is fannings, and what is obtained from third level screen cloth tea outlet is dust tea, from first order screen cloth tea outlet,
Second level screen cloth tea outlet is respectively equipped with tealeaves conveying band logical and enters tea mouth to tea winnower；Go out from third level screen cloth tea outlet
The dust tea come will not enter back into tea winnower selection by winnowing；
C, the tea winnower tea outlet has four, by being the first tea outlet successively away from induced-draught fan distance, second go out tea
Mouth, the 3rd tea outlet, the 4th tea outlet, the first tea outlet is farthest away from induced-draught fan, and the weight such as impurity in tealeaves will go out tea from this
Mouth discharge；Other three tea outlets respectively obtain three kinds of tealeaves to vary in weight；Therefore, go out from tealeaves circular screening machine first order screen cloth
The tea mouth compass screen surface tea that comes of conveying by second, third, the 4th tea outlet respectively obtain 1-2,1-3,1-4 machine mouth tea, circular screening machine
The two level screen cloth tea outlet fannings that comes of conveying by second, third, the 4th tea outlet mouth respectively obtain 2-2,2-2,2-2 machine mouth
Tea, the machine mouth tea come out from the second tea outlet is identity tea, and the machine mouth tea come out from the 3rd tea outlet goes out tea for secondary tea, from the 4th
The machine mouth tea of mouth out is tablet tea；The tea outlet of identity tea second is provided with conveyer belt, leads to the tea inlet port of tea stalks picking-out machine；The
3rd, the 4th tea outlet, which is provided with, contains tea container, and obtained secondary tea, tablet tea do not enter back into tea stalks picking-out machine and carry out stalk-sorting operation；
D, above-mentioned two kinds of identity tea by tea winnower selection by winnowing, the configured conveyer belt in the second tea outlet are transported to described
Tea stalks picking-out machine carries out stalk-sorting operation, when identity tea passes through tea stalks picking-out machine；Longer tea stalk enters stalk-sorting across bull stick
The stalk outlet of machine, shorter tealeaves directly from the tea outlet discharge being located at below tea stalks picking-out machine, obtain the positive tea of two kinds of standards.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
1st, the present invention is connected the tea outlet of various separating screen devices with tea mouth is entered by tea-conveying device, makes tea screening equipment
Operated from separate unit and be changed into a production line operation, effectively improved screening efficiency, greatly reduce cost of labor, also improve tea
Leaf production efficiency.
Embodiment
