Tom qab fermentation, cov tshuaj yej dub xav tau ibTea Leaf Dryer. Fermentation yog ib theem tshwj xeeb ntawm cov tshuaj yej dub ntau lawm. Tom qab fermentation, cov xim ntawm nplooj hloov ntawm ntsuab mus rau liab, tsim cov yam ntxwv zoo ntawm cov tshuaj yej dub, liab nplooj thiab kua zaub liab. Tom qab fermentation, cov tshuaj yej dub yuav tsum tau qhuav sai sai los yog qhuav. Txwv tsis pub, yog tias nws khaws cia ntev dhau lawm, nws yuav ua rau muaj ntxhiab tsw ntxhiab. Cov txheej txheem ziab yog muab faib ua ob theem: pib ziab nrog hluav taws kub thiab redrying nrog hluav taws tag nrho.

Kev ziab ntawm cov tshuaj yej dub yog txheej txheem uas fermented tshuaj yej puag yog roasted ntawm qhov kub thiab txias kom sai evaporate cov dej thiab ua tiav ib tug zoo-preserving dryness. Nws lub hom phiaj yog peb zaug: siv qhov kub thiab txias kom sai sai inactivate enzyme kev ua si thiab nres fermentation; kom evaporate dej, txo qhov ntim, kho cov duab, thiab tswj kom qhuav kom tsis txhob muaj mildew; kom emit feem ntau ntawm cov qis-boiling point nyom tsw, intensify thiab khaws high-boiling point aromatic tshuaj, thiab tau lub cim qab zib aroma ntawm dub tshuaj yej.

Thaum ua cov tshuaj yej dub, ua ntej xaiv cov buds uas tsim nyog thiab nplooj raws li cov kev xav tau ntawm cov tshuaj yej dub, thiab qhuav cov nplooj tshiab kom txog thaum lawv qhuav. Qhov no tso cai rau cov nplooj tshiab kom evaporate dej kom tsim nyog los txhim kho lawv cov toughness thiab yooj yim shaping. Tom qab ntawd cov tshuaj yej nplooj yog muab tso rau hauv ib tugTshuaj yej Roaster tshuabntawm li 200 ° C thiab do-kib kom puas cov nplooj hlwb thiab secrete tshuaj yej kua txiv, ua cov tshuaj yej nplooj ntawv nruj nreem ropes thiab nce lub concentration ntawm cov tshuaj yej kua zaub. Cov nplooj tshuaj yej ces muab tso rau hauv ib qho tshwj xeebTshuaj yej fermentation tshuablos yog fermentation chamber rau ferment, kom cov tshuaj yej nplooj tsim cov yam ntxwv ntawm nplooj liab thiab kua zaub liab.

Cov kauj ruam kawg yog ziab. Siv aTshuaj yej tshuab ziab khaub ncawskom qhuav ob zaug. Thawj zaug yog hluav taws kub, thiab lub thib ob yog hluav taws tag nrho. Qhov no tso cai rau cov tshuaj yej dub kom evaporate dej, ceev cov tshuaj yej sticks, kho cov duab, kom nws qhuav, thiab disperse cov tshuaj yej dub. Cov tsw ntsuab ntawm cov tshuaj yej khaws cov ntxhiab tsw qab ntawm cov tshuaj yej dub.
