Raw shinkafa fur man yana ƙunshe da kyauta mai acid, fur wax, phospholipids, furotin, pigments, kamar yadda abinci man yana buƙatar ƙarin tsarkakewa da refinement, kawar da waɗannan ƙarancin halitta.

Easy refinement tsari na kananan shinkafa mai masana'antu kamar haka:

Crude shinkafa man fetur → Dehydration → kawar da wax → hydration → alkali refinement → ruwa wanke → dehydration → deodorization → tsarkake shinkafa man fetur

① kawar da gargajiya - dumama man fetur zuwa 90 ℃, tace tare da matsa lamba tace.

② kawar da waxes - waxes abun ciki a cikin sandwich man fetur ne yau da kullun 3% -5%. Fragrance wax ba za a iya sha ta jikin mutum ba, ba shi da darajar abinci, dole ne a cire shi don kada a shafi ingancin man fetur.

② hydration - farko dumama raw shinkafa bran man fetur zuwa 65-70 ℃, sa'an nan kuma ƙara ruwa mai zafi mafi daidai da 5% na yawan man fetur a ƙarƙashin juyawa, juyawa 40-60min, dakatar da dumama lokacin da zafin jiki ya tashi zuwa 80 ℃, sa'an nan kuma juyawa na minti 25, tsayawa na sa'o'i 4-6.

② alkali refining - kafin alkali refining farko auna acid farashin crude shinkafa man fetur, daidai da wadannan formula lissafa kara alkali adadin:

Abubuwan da ake amfani da alkali mai ƙarfi ((kg) = ingancin man fetur ((t) X farashin acid X 0.713

A cikin formula, 0.713 shine adadin nauyin sodium hydroxide da potassium hydroxide.

Sa'an nan aka haɗa 18 ~ 20ºBe mai rarraba alkali ruwa, sa mai mai mai ruwa a cikin alkali tank, sa'ad da sabulu ya bayyana a bayyane, mai dumama (1 ℃ / min), mai da aka yi a gida da sabulu ya bayyana a layered, dakatar da dumama, ƙarshen zafin jiki ba ya wuce 80 ℃, saurin motsawa ya sauka zuwa 40r / min, kuma ƙara matattarar 3% -5% na ruwan gishiri mai zafi, sa'ad da sabulu ya bayyana launin toka da baƙar fata kuma ya nutse, dakatar da ƙara ruwan gishiri, ci gaba da motsawa na mintuna 10, tsaya, sa'ad da sabulu ya kasance duk a ƙasa, sa'ad da man ya bayyana mai rarraba, saki

② Idan ruwan sharar gida har yanzu yana nuna ja ta hanyar gwajin phenol phthalate, ana buƙatar wanki har sai sakamakon gwajin phenol phthalate bai nuna jan ma'aunin pH ba ya nuna tsaka tsaki.

• dehydration - dumama man fetur zuwa 105 ~ 110 ℃, a karkashin motsawa har sai wani kumfa ya bayyana a kan man fetur, bayan dehydration, shi ya kamata ya kasance ƙasa da 0.2%.

Ƙara adadin ne kimanin 2% na shinkafa man fetur nauyi, daga 0.5 sa'o'i bayan motsawa, samfurin lura, idan ya dace da misalai, za a iya shiga gaba tsari. In ba haka ba, har yanzu ana buƙatar maimaita launi sau da yawa har sai mai ya zama rawaya da haske.

Deodorization - yafi cire oxides a man fetur, kamar keto, aldehyde, free acid da sulfur-dauke da mahada da sauransu, wadannan abubuwa da ke wanzu a cikin man fetur, sa man fetur nuna musamman "wari", don haka ya kamata a cire shi. Deodorization ne yawanci a cikin inji jihar (watau 60mmHg) a cikin overheating tururi, sa man fetur zafin jiki ya tashi zuwa 220 ° C sama, sarrafawa 4 ~ 6, sa'an nan kuma rage man fetur zafin jiki zuwa 40 ~ 60 ° C, canza a cikin sanyaya man fetur tank, da halitta sanyaya, watau, dole ne a tsarkake shinkafa man fetur.
