Shayi mai baƙar fata shine shayi cikakke, kuma yana aiki da tsarin sinadarai na sinadarai, wanda ke canza yanayin sunadarai na musamman da launuka na musamman. Teaƙƙarfan shayi gabaɗaya yana da halayen "ja miya da ganye ja".

Shine mai baƙar fata na kasar Sin ya haɗa da Souchong Blacke shayi, Gongfo Black shayi da kuma fashe shayi. Soochong Blacke shayi shine tsohuwar shayi na baki. An samo asali ne a cikin dutsen Wuyi kuma shine asalin sauran baƙar fata. Akwai nau'ikan nau'ikan shayi na Gongfu, kuma asalin ma ya bambanta. Misali, babban samar da Qimen Gongfu Black shayi a cikin Qiren County, Anhui, da Yunnan ja sea gongfo, da sauransu.; Ana rarraba shayi mai baƙar fata da baƙi, galibi don fitarwa.

A kan aiwatar da aiki, reacterization polymerization na shaye shaye shaye shaye shaye shaye shaye shaye shaye shaye shaye-shaye-shaye-shaye-shaye-shaye-shaye-shaye-shaye-shaye-shaye-shaye-shaye-shaye-shaye-shaye-shaye-shaye-shaye-shaye-shaye suka samar da abubuwa masu launin fata kamar Theaflavins, daakar kuma andau. Wadannan abubuwa, tare da maganin kafean, amino acid na kyauta, solable sugars da sauran kayan haɗin ciki, yana shafar launi da dandano da ɗanɗano shayi; A lokaci guda, glycosides enzymatic hydrolysissism hydrolysis saki terpene saki terpene sakin terpene yana shafar nau'in kitse mai yawan kitse wanda ba a yi amfani da nau'in ƙanshi ba.

Hanyar yin baƙar fata baƙar fata ba ta da matsala, kuma fasahar sarrafawa ta haɗa da matakai huɗu na withering, mirgina, fermentation da bushewa. Wadanne nauyi wadannan wadannan hanyoyin yin amfani da su wajen samar da baƙar fata?

1.witering.

Witering shine tsari na farko a farkon samar da baƙar fata, kuma yana kuma ainihin tsari don samar da ingancin shayi. Wititeri yana da abubuwa biyu:

Daya shine a ƙafe ɓangare na ruwa, ku rage tashin hankali sel na shayi, sa ganye mai tushe, ƙara tauri daga cikin buds da ganye, kuma sa sauƙi a juya cikin tube.

Na biyu yana dacewa da canje-canje a cikin abubuwan da abubuwa. Saboda asarar ruwa, rashin daidaituwa na membrane membrane an inganta shi, kuma dauke da enzymes na sannu a hankali a cikin abubuwan shayi na ƙirar shayi da kamshi.

2. Kneadmiyar (mirgina)

Kneading (yankan) tsari ne mai mahimmanci don Gongfo Black shayi da karye baƙar fata don tsara kyakkyawan tsari da kuma samar da ingancin ciki. Gongfu Black shayi yana buƙatar bayyanuwa mai girma da dandano mai ƙarfi na ciki, wanda ya dogara da matakin girman ganye da lalata ƙwayar ƙwayar ƙarfe.

Akwai ayyuka uku na mirgina:

Na farko shine lalata kyallen sel ɗin ganye ta hanyar birgima oxsidation, saboda ruwan 'ya'yan enzymat.

Na biyun shine mirgine da hasken da igiya madaidaiciya, rage siffar jiki, kuma ƙirƙirar kyakkyawan bayyanar.

Na uku shine cewa ruwan shayi ya cika da tara a farfajiya na ganye, wanda yake a sauƙaƙe a cikin ruwa yayin fitar da miyan shayi da oily bayyanar.

3. Fermentation

Fermentation tsari ne na maɓalli don samuwar launin baƙar fata, ƙanshi, da kuma ingancin halayen ingancin. Kawai fermentation na kyau ne na iya samar da karin Thaflavin da Thearobigen, kazalika da ƙarin dandano da kayan ƙanshi.

Fermentation tsari ne mai ci gaba, ba tsari ba. Fermentation ya wanzu koyaushe tunda aka birgima shayi da bushe. Yawancin lokaci, an saita tsarin fermentation na musamman kafin bushewa bayan rolling, saboda shayi na iya isa matakin da ya fi dacewa.

A lokacin da baƙar fata shayi yake da shi, ganyen shayi na ganyayyaki an sanya shi a cikin firam ɗin fermentation ko keken shanu, sannan a saka ɗakin tanki ko fermentation don fermentation. A cikin 'yan shekarun nan, an haifi wasu kayan aikin fermentation. Fermentation dole ne ya cika yawan zafin jiki mai kyau, laima da iskar oxygen da ake buƙata don oxlymerization na ohymerization na shayi na shayi.

4. Dry.

Ana bushewa ta hanyar bushewa, gaba ɗaya ya kasu kashi biyu, a karo na farko ana kiranta wuta, a karo na biyu wuta wuta. Gashi da wuta wuta suna buƙatar yada sanyi.

Bushewa kuma yana yin dalilai uku:

Na farko shine amfani da babban zazzabi ga ayyukan enzyme, dakatar da iskar opzymic, kuma gyara ingancin fermentation.

Na biyun shine kwararar ruwa, yana girgiza shayi na shayi, gyara siffar, kuma ka kwashe ƙafafunsu.

Na uku shine don haifar da yawancin ciyawar wari mai rauni tare da ƙaramar tafasasshen tafasasshen yanayi tare da babban tafasasshen yanayi.
