Black tea processing•Kuyanika

Kuyanika ndi gawo lomaliza pakukonza tiyi wakuda komanso gawo lofunikira pakuwonetsetsa kuti tiyi wakuda ndi wabwino.

Kumasulira kwa njira zowumitsa ndi njira

Tiyi wakuda wa Gongfu nthawi zambiri amawumitsidwa pogwiritsa ntchito aMakina owumitsira tiyi. Zowumitsira zimagawidwa kukhala mtundu wa louver wamanja ndi zowumitsa unyolo, zonse zomwe zingagwiritsidwe ntchito. Nthawi zambiri, makina owumitsira makina amagwiritsidwa ntchito. Ukadaulo wophika wowuma umawongolera kutentha, kuchuluka kwa mpweya, nthawi ndi makulidwe a masamba, ndi zina zambiri.

(1) Kutentha ndiye chinthu chachikulu chomwe chimakhudza kuyanika bwino. Poganizira zofunikira za madzi osungunuka ndi kusintha kwa endoplasmic, "kutentha kwakukulu kwa moto woopsa ndi kutentha kochepa kwa moto wathunthu" kuyenera kuphunzitsidwa bwino. Nthawi zambiri,chowumitsira tiyi cha intrgralamagwiritsidwa ntchito, ndipo kutentha kwa mpweya wamoto wosaphika ndi 110-120 ° C, osapitirira 120 ° C. Kutentha kwa moto wathunthu ndi 85-95 ° C, osapitirira 100 ° C; nthawi yozizira pakati pa moto wosaphika ndi moto wathunthu ndi mphindi 40, osapitirira 1 ora. Moto watsitsi umatenga kutentha kwapakati, komwe kumatha kuyimitsa makutidwe ndi okosijeni a enzymatic, kutulutsa madzi mwachangu, ndikuchepetsa kutentha ndi chinyezi.

(2) Kuchuluka kwa mpweya. Pazifukwa zina, kuwonjezera kuchuluka kwa mpweya kumatha kuwonjezera kuchuluka kwa kuyanika. Ngati kuchuluka kwa mpweya sikukwanira, mpweya wamadzi sungathe kutulutsidwa kuchokera kuMakina Otentha Owumitsa Ovunim'kupita kwanthawi, zomwe zimapangitsa kutentha kwambiri, chinyezi komanso zinthu zambiri, zomwe zimakhudza kupanga tiyi. Ngati mpweya uli waukulu kwambiri, kutentha kwakukulu kumatayika ndipo mphamvu ya kutentha idzachepetsedwa. Nthawi zambiri, liwiro la mphepo ndi 0.5m/s ndipo voliyumu ya mpweya ndi 6000m*3/h. Kuonjezera zida zochotsera chinyezi pamwamba pa chowumitsira kumatha kuwonjezera kuyanika ndi 30% -40% ndikuwongolera kuyanika bwino.

(3) Nthawi, moto waukali uyenera kukhala wotentha kwambiri komanso wamfupi, nthawi zambiri 10-15 mphindi ndi yoyenera; moto wathunthu uyenera kukhala wocheperako komanso wowuma pang'onopang'ono, ndipo nthawi iyenera kuonjezeredwa moyenera kuti fungo lizikula bwino, mphindi 15-20 ndizoyenera.

(4) Makulidwe a masamba otambasuka ndi 1-2cm pamasamba amoto aubweya, ndipo amatha kukhuthala mpaka 3-4cm moto ukadzadza. Kukulitsa moyenerera makulidwe a masamba ofalikira kutha kugwiritsa ntchito mphamvu zonse za kutentha ndikuwongolera kuyanika bwino. Ngati masamba ofalikira ali ochuluka kwambiri, sikuti kuyanika kokha sikungapangidwe bwino, koma khalidwe la tiyi lidzachepetsedwa; ngati masamba ofalikira ali ochepa kwambiri, kuyanika bwino kudzachepetsedwa kwambiri.

mlingo wa kuuma

Chinyezi cha masamba amoto waubweya ndi 20% -25%, ndipo chinyontho chamasamba oyaka moto ndi osakwana 7%. Ngati chinyezi ndi chochepa kwambiri chifukwa cha kuyanika muKuyanika Makina, ndodo za tiyi zimathyoka mosavuta panthawi yoyendetsa ndi kusungirako, zomwe zimapangitsa kuti zikhale zotayika komanso zosathandiza kusunga maonekedwe.

Kuyanika Makina

M'zochita, nthawi zambiri amagwidwa potengera zomwe wakumana nazo. Masamba akauma 70 mpaka 80%, masambawo amakhala owuma komanso olimba, ndipo timitengo tating'ono timafewa pang'ono; masamba akauma mokwanira, zimayambira zimasweka. Gwiritsani ntchito zala zanu kupotoza timitengo kuti tipange ufa.
