o Shaft mai juyawa da gogewa: A ciki, akwai shaft mai juyawa tare da maƙurar gogewa masu sassauƙa ko masu tauri da yawa a haɗe, waɗanda suka manne sosai da bangon ciki na silinda.
o Na'urar tuƙi: Mota tana tuƙa sandar don juyawa da sauri mai yawa (yawanci 100-500 rpm).
2. Tsarin Aiki
o Tasirin gogewa: Masu gogewa suna ci gaba da goge kayan daga bangon ciki, suna hana gurɓatawa ko lu'ulu'u, kuma a lokaci guda suna tilasta sabunta layin iyaka akan saman canja wurin zafi, wanda ke ƙara yawan canja wurin zafi sosai (har sau 5-10 na masu musayar zafi na bututu na gargajiya).
o Aikin haɗawa: Masu gogewa masu juyawa suna yin tasirin yankewa da motsawa akan kayan, suna haɓaka yanayin zafi da abun da ke ciki iri ɗaya.
o Kula da canjin lokaci: Ta hanyar daidaita zafin jaket ɗin da saurin scraper daidai, ana iya cimma saurin sanyaya, lu'ulu'u ko emulsification na kayan (kamar sarrafa lu'ulu'u mai kitse a cikin margarine).
3. Fa'idodi da Halaye
o Ya dace da yawan danko (har zuwa 10^5 cP), ruwaye marasa Newtonian ko kayan da ke ɗauke da ƙwayoyin cuta masu tauri.
o Yana guje wa yanayin zafi ko sanyi a yankin, yana tabbatar da ingancin samfurin iri ɗaya.
o Zai iya sarrafa kayan da ke da saurin kamuwa da cutar coking ko crystallization.
II. Amfani da shi a Samar da Margarine
1. Muhimmin Matsayi a Tsarin Samarwa
Samar da margarine yana buƙatar emulsification na mai da matakan ruwa (madara, gishiri, emulsifiers, da sauransu) sannan a biyo baya da sanyaya da sauri. Mai musayar zafi na saman da aka goge babban na'ura ce, wacce galibi ake amfani da ita a:
o Sanyaya da kuma haɗakar emulsions: Sanyaya da sauri sanyaya gaurayen emulsion (kimanin 40-50°C) zuwa 10-20°C don haifar da samuwar tsarin lu'ulu'u mai ɗorewa (mahimmanci don laushin rubutu).
o Sarrafa Nucleation: Ƙarfin yankewar maƙeran yana karya manyan lu'ulu'u, yana samar da hanyar sadarwa mai kyau da daidaito, yana ƙara ƙarfin faɗaɗa kirim ɗin.
o Maganin hana haihuwa: A wasu hanyoyin, ana amfani da jaket masu zafi sosai don hana haihuwa na ɗan gajeren lokaci (misali, 85°C na tsawon daƙiƙa 15).
2. Daidaitawar Masana'antu
o Daidaitaccen tsarin kula da zafin jiki: Tsarin kitse yana da saurin amsawa ga yanayin zafi (misali, ana buƙatar sarrafa man dabino a 20-25°C), kuma na'urar musayar zafi da aka goge za ta iya kiyaye yanayin zafin daidai.
Rigakafin rabuwar matakai: Ƙarfin yankewa mai yawa yana tabbatar da wargajewar matakin ruwa iri ɗaya, yana guje wa rabuwar mai da ruwan.
o Kula da kayan mai mai yawa: Margarine yana ɗauke da kashi 70-80% na kitse, kuma ƙirar scraper ɗin ta shawo kan matsalar toshewar na'urorin musanya zafi na gargajiya.
3. Sigogi na Kayan Aiki na yau da kullun
o Ma'aunin canja wurin zafi: 500-1500 W/(m²·K) (ya danganta da danko na kayan).
o Saurin sanyaya: Har zuwa 30°C/minti (mahimmanci ga motsin kitse na crystallization).
o Ƙarfin aiki: Kayan aiki na sikelin masana'antu na iya ɗaukar tan 1-10 a kowace awa.
III. Kwatanta da Sauran Masu Canja Zafi
Amfani da margarine ★★★★★ ★★☆ ★☆☆
| Halaye | Mai Canja Zafi na Surface Mai Gogewa | Shell da Tube Heat Exchanger | Canjin Zafi na Faranti |
| Danko mai dacewa | Babban (≤10^5 cP) | Matsakaici-ƙasa (≤10^3 cP) | Ƙasa (≤10^2 cP) |
| Haɗarin lalacewa | Ƙasa sosai (tsaftace kai ta hanyar gogewa) | Babban | Matsakaici |
| Tasirin aski | Mai ƙarfi (wanda za a iya sarrafa shi) | Mai rauni | Mai rauni |
IV. Yanayin Ci gaban Masana'antu
• Inganta makamashi: Yi amfani da injinan mita masu canzawa don daidaita saurin scraper, daidaita buƙatun dabara daban-daban (misali, mafi girman yankewa don kirim mai ƙarancin mai).
• Kulawa mai hankali: Haɗa na'urori masu auna zafin jiki don daidaita saurin sanyaya da ƙarfin yankewa a ainihin lokaci. • Tsarin tsafta: Ta bin ƙa'idodin EHEDG/3A, tsarin CIP (Clean-In-Place) yana rage lokacin aiki.
Na'urar musayar zafi ta scraper, tare da iyawarta ta canja wurin zafi da haɗawa mai inganci, ta zama muhimmiyar kayan aiki a masana'antar margarine. Musamman a ƙarƙashin yanayin neman samfuran da ba su da kitse mai yawa da kuma waɗanda ke da ƙarancin aiki, za a ƙara haskaka fa'idodin sarrafa shi.
