Tshuaj yej ntsuab yog cov tshuaj yej uas tsis yog-fermented, uas yog tsim los ntawm cov txheej txheem ntawm fixation, dov, ziab thiab lwm yam txheej txheem.Cov khoom ntuj tsim nyob rau hauv nplooj tshiab yog khaws cia, xws li tshuaj yej polyphenols, amino acids, chlorophyll, vitamins, thiab lwm yam. Cov txheej txheem txheej txheem ntawm cov tshuaj yej ntsuab yog: kis → kho → kneading → ziab.
Tom qab cov nplooj tshiab raug xa rov qab mus rau lub Hoobkas, lawv yuav tsum tau kis rau ntawm lub pallet huv.Lub thickness yuav tsum yog 7-10 cm.Lub sij hawm withering yuav tsum yog 6-12 teev, thiab nplooj yuav tsum tig nyob rau hauv nruab nrab.Thaum cov dej ntsiab lus ntawm cov nplooj tshiab nce mus txog 68% mus rau 70%, cov nplooj zoo ua mos, thiab cov ntxhiab tsw tawm, cov tshuaj yej fixation theem tuaj yeem nkag mus.
Kev kho yog txheej txheem tseem ceeb hauv kev tsim tshuaj yej ntsuab.Kev kho yog ua kom kub ntsuas kub kom dissipate cov dej noo nyob rau hauv nplooj, inactivate cov kev ua ntawm enzymes, thiab ua tej yam tshuaj hloov nyob rau hauv cov ntsiab lus ntawm cov nplooj tshiab, yog li tsim cov yam ntxwv zoo ntawm ntsuab tshuaj yej.Kev kho tshuaj yej ntsuab siv cov ntsuas kub kom tsis txhob ua haujlwm ntawm cov enzymes thiab inhibit cov tshuaj tiv thaiv enzymatic.Yog li ntawd, xyuam xim rau qhov tseeb tias yog tias lub lauj kaub kub qis dhau thiab cov nplooj kub nce mus ntev heev thaum lub sijhawm kho tshuaj yej, cov tshuaj yej polyphenols yuav dhau los ua cov tshuaj tiv thaiv enzymatic, ua rau "liab qia liab nplooj".Ntawm qhov tsis sib xws, yog tias qhov kub thiab txias dhau lawm, ntau chlorophyll yuav raug rhuav tshem, ua rau cov nplooj tig daj, thiab qee qhov ua rau hlawv cov npoo thiab pob, txo qhov zoo ntawm cov tshuaj yej ntsuab.
Ntxiv nrog rau ob peb qib high-qib teas, uas yog ua tiav los ntawm tes, feem ntau ntawm cov tshuaj yej yog ua tiav mechanically.Feem ntau, atshuaj yej drum-fixation tshuabyog siv.Thaum kho tshuaj yej, ua ntej tig lub tshuab kho thiab ua rau hluav taws kub tib lub sij hawm, kom lub qhov cub hluav taws kub sib npaug thiab tsis txhob muaj cua sov ntawm lub thoob.Thaum muaj qee qhov me me ntawm lub raj, qhov kub nce mus txog 200′t3 ~ 300′t3, uas yog, cov nplooj tshiab tau muab tso rau hauv. Nws yuav siv li 4 mus rau 5 feeb los ntawm cov nplooj ntsuab mus rau nplooj., Feem ntau hais lus, tswv lub hauv paus ntsiab lus ntawm "kev kho kub kub, kev sib xyaw ua ke ntawm kev tho txawv thiab ntuav, tsis tshua tho txawv thiab ntau ntu, cov nplooj qub raug tua, thiab cov nplooj hluas raug tua thaum laus".Tus nqi ntawm cov nplooj ntawm lub caij nplooj ntoos hlav tshuaj yej yuav tsum tau tswj ntawm 150-200kg / h, thiab cov laus nplooj ntawm lub caij ntuj sov tshuaj yej yuav tsum tau tswj ntawm 200-250kg / h.
Tom qab kho nplooj, nplooj yog tsaus ntsuab nyob rau hauv cov xim, cov nplooj yog mos thiab me ntsis nplaum, stems yog tas li folded, thiab cov roj ntsuab ploj thiab cov tshuaj yej fragrance overflows.
