Black tea matcha powder inogadzirwa kubva kumashizha etii matsva kuburikidza nekuoma, kukunguruka, kuvirisa, kupera simba uye kuomesa, uye ultrafine kugaya. Hunhu hwayo hwemhando hunosanganisira dzakapfava uye dzakafanana zvimedu, shava tsvuku ruvara, mellow uye kutapira kuravira, kunhuhwirira kwakapfuma, uye yakadzika tsvuku soup color.

Kana ichienzaniswa neyakajairwa tii nhema, dema tii poda ine saizi yakanaka kwazvo (inowanzo kutenderera mazana matatu mesh), uye ruvara rwayo, kuravira, uye kunhuhwirira kwakangofanana neyakajairwa tii nhema. Mashizha matsva etii muchirimo, zhizha, uye matsutso anogona kugadzirwa ese akaitwa ultrafine dema tii hupfu, uye zhizha nematsutso mashizha manyoro ndiwo akanakisa zvigadzirwa.

Kugadzira matanho eupfu hwetii nhema: Mashizha matsva → Kusvava (kusvava kwechisikigo, kusvava mumudziyo uri kusvava, kana kusvava nechiedza chezuva) → Kukunguruka → Kupwanya uye kuongorora, kuvirisa → Kupera mvura uye kuomesa → Kukuya zvakanaka kwazvo → Kupedzwa kwechigadzirwa.

(1) Kusvava

Chinangwa chekuoma chakafanana nekugadzirisa nguva dzose tii nhema.

Kune nzira nhatu dzekusvava: chinwiro chinosvava, kusvava kwechisikigo, uye kusvava kwezuva. Iyo chaiyo nzira dzakafanana neye black tea processing. Wilting degree: Nzvimbo yeshizha inorasikirwa nekupenya kwayo, ruvara rweshizha rwakasvibira, mhando yeshizha yakapfava, inogona kukandwa mubhora nemaoko, dzinde rinogara rakapetwa, hapana mabuds akasvava, mipendero yakatsva, kana tsvuku. mashizha, uye hwema hwouswa hwakasvibirira hwanyangarika zvishoma, hune hwema hushoma. Kana hunyoro hukashandiswa kudzora, hunyoro hunofanirwa kuchengetedzwa pakati pe58% ne64%. Kazhinji, iri 58% kusvika 61% muchirimo, 61% kusvika 64% muzhizha nematsutso, uye uremu hwekurasikirwa kwemashizha matsva hunofanira kuva pakati pe30% ne40%.

(2) Kuumburuka

Kukungurutsa tii nhemapoda haidi kutariswa kuti yakaumbwa sei. Chinangwa chayo ndechekuparadza masero emashizha, kubvumira polyphenol oxidase mumashizha kuti inosangana ne polyphenolic compounds, uye kukurudzira kuvirisa kuburikidza nekuita kweokisijeni mumhepo.

Rolling tekinoroji: Tembiricha yemukamuri yekukungurusa dema tii poda inodzorwa pa20-24 ℃, ine hunyoro hwe85% -90%. Inogona kuitwa uchishandisa 6CR55 rolling muchina. Technical parameters: Kudya kwemashizha kwedhiramu rimwe chete kana muchina kunosvika 35kg; Kukwesha nekumonyorora kunofanira kuitwa mumatanho kweanenge maminetsi makumi manomwe, nezvinhu zvegiredhi rekutanga kana pamusoro zvichikanywa katatu, nguva yega yega kwemaminitsi makumi maviri, makumi matatu, uye makumi maviri zvichiteerana; Geda zvishandiswa pazasi pedanho rechipiri kaviri, nguva yega yega kwemaminitsi makumi matatu nemashanu, uye usashandise kumanikidza kwemaminetsi makumi matatu nemashanu ekutanga.

Rolling degree: Mashizha anomonereka uye anonamira neruoko, achibvumira muto wetii kuti unyatsokandwa pasina kurasikirwa. Mashizha acho akatsvuka zvishoma uye anobudisa hwema hwakasimba.

(3) Kupatsanura uye kuongorora

Mushure mekukunguruka kwega kwega, tii inofanira kuparadzaniswa uye kusefa, uye tei yakarongwa inofanira kuviriswa zvakasiyana.

(4) Kuvirisa

Chinangwa chekuvirisa ndechekuwedzera activation level yema enzymes, kukurudzira oxidation yepolyphenolic compounds, kuburitsa kunhuhwirira kwakapfuma mumashizha, uye kuumba ruvara uye kuravira kweultrafine dema tii poda. Fermentation tekinoroji: tembiricha yemukati ye25-28 ℃, humidity inopfuura 95%. Paridzai mashizha manyoro ane hukobvu hwe6-8cm uye mashizha epakati nepakati nehupamhi hwe9-10cm, uye kuvirisa kwe2.5-3.0h; Mashizha ekare ari 10-12 cm uye nguva yekuvirisa maawa 3.0-3.5. Fermentation degree: Mashizha matsvuku muruvara uye anoburitsa kunhuhwirira kwakasimba kweapuro.

(5) Kupererwa nemvura uye kuomeswa

① Dehydration uye kuomesa chinangwa: Kushandisa tembiricha yakakwira kuparadza chiitiko che enzyme, misa kuvirisa, uye gadzirisa mhando yakaumbwa. Kubuda kwemvura kunoramba kuchiburitsa kunhuhwirira kwehuswa hwakasvibira, zvichiwedzera kunhuhwirira kwetii.

② Dehydration uye kuomesa tekinoroji: Mushurekuvirisa, mashizha akaumba ruvara rwetii yakadzikama. Naizvozvo, nyaya dzekudzivirira kwemavara dzinogona kufuratirwa kana uchigadzira ultrafine dema tii poda kuburikidza nekupera mvura uye kuomesa, uye zvishandiso zvinogona kushandiswa neyakaomesesa. Kuomesa kunokamurwa kuva kuomeswa kwekutanga uye kuomeswa kwakakwana, nenguva yekutonhora kwemaawa 1-2 pakati. Iyo musimboti wekushisa kwepamusoro uye kumhanya kunonyanya kudzidziswa panguva yekutanga kuomeswa, ine tembiricha inodzorwa pa100-110 ℃ kwemaminetsi 15-17. Mushure mekuoma kwekutanga, hunyoro hwemashizha huri 18% -25%. Pakarepo inotonhorera pasi mushure mekuoma kwekutanga, uye mushure memaawa 1-2 ekugoverazve mvura, ita kuomesa tsoka. Kuomeswa kwetsoka kunofanira kutevera mitemo yekushisa kwakadzika uye kunonoka kuoma. Tembiricha inofanira kudzorwa pa90-100 ℃ kwemaminitsi 15-18. Mushure mekuoma kwetsoka, hunyoro hwemashizha hunofanira kuva pasi pe5%. Panguva ino, mashizha anofanira kuputswa kuita upfu nemaoko, ane ruvara rwakasviba uye rwakatsetseka uye kunhuhwirira kwakasimba.

(6) Ultrafine pulverization

Iyi nzira inosarudza kukura kwechidimbu cheblack tea powderzvigadzirwa uye inotora basa rakasimba mumhando yechigadzirwa. Kufanana negirinhi tii poda, dema tii poda ine dzakasiyana ultrafine nguva dzekukuya nekuda kwehunyoro hwakasiyana hwezvigadzirwa. Iyo yakura iyo mbishi, inorebesa nguva yekukuya. Mumamiriro ezvinhu akajairwa, midziyo yekupwanya inoshandisa iyo yakatwasuka tsvimbo nyundo musimboti inoshandiswa pakupwanya, ine imwechete blade kudyisa 15kg uye nguva yekupwanya yemaminetsi makumi matatu.

(7) Yakapedzwa chigadzirwa kurongedza

Kufanana negirinhi yehupfu yehupfu, zvigadzirwa zvitema zvehupfu zvine zvidimbu zvidiki uye zvinokwanisa kutora unyoro kubva mumhepo patembiricha yekamuri, zvichiita kuti chigadzirwa chiwedzere uye chiparare munguva pfupi. Yakagadzirwa dema tii poda inofanirwa kuvharwa nekukasira uye kuchengetwa munzvimbo inotonhora ine hunyoro huri pasi pe50% uye tembiricha ye0-5 ℃ kuve nechokwadi chemhando yechigadzirwa.
