Gukoresha ibikoresho byo gukwirakwiza ubushyuhe mu nganda za Margarine
Ibikoresho byo kohereza ubushyuhe bikozwe mu buryo bwa scraped surface (SSHE) ni ibikoresho byo kohereza ubushyuhe bikora neza cyane kandi byongera ubushyuhe binyuze mu gukurura hakoreshejwe ikoranabuhanga. Bikwiriye cyane cyane ibinyabutabire bifite ubushyuhe bwinshi, byoroshye gushushanya cyangwa birimo uduce duto. Ibi bikurikira ni isesengura ry'imikorere yabyo n'ikoreshwa ryabyo mu nganda za margarine:
I. Ihame ry'imikorere y'ibikoresho byo gukwirakwiza ubushyuhe ku butaka byashizweho
1. Imiterere y'ibanze
o Silinda ifite ikoti: Igice cyo hanze gitangwa n'ibikoresho bishyushya/bikonjesha (nk'umwuka, amazi akonje cyangwa amavuta yo kohereza ubushyuhe).
o Umugozi n'umugozi bizunguruka: Imbere, hari umugozi uzunguruka ufite udukoresho twinshi tworoshye cyangwa dukomeye dufatanye, dufata neza urukuta rw'imbere rw'umugozi.
o Igice cyo gutwara: Moteri iyobora umugozi kugira ngo uzunguruke ku muvuduko wo hejuru (ubusanzwe 100-500 rpm).
2. Uburyo bwo gukora
o Ingaruka zo gukurura: Udukoresho duhora dukura ibikoresho ku rukuta rw'imbere, bikarinda kwangirika cyangwa gushonga, kandi icyarimwe bigatera imbaraga kuvugurura urwego rw'umupaka ku buso bwo kohereza ubushyuhe, byongera cyane ubushobozi bwo kohereza ubushyuhe (kugeza ku nshuro 5-10 z'udukoresho dusanzwe two kohereza ubushyuhe).
o Imikorere yo kuvanga: Ibikoresho bizenguruka bigira ingaruka zo gukata no gukangura ibikoresho, bigatuma ubushyuhe n'imiterere bingana.
o Guhindura icyiciro: Mu guhindura neza ubushyuhe bw'ikoti n'umuvuduko wo gusya, gukonjesha vuba, gushushanya cyangwa gusya ibikoresho bishobora kugerwaho (nk'ukugenzura gushushanya ibinure muri margarine).
3. Ibyiza n'imiterere
o Bikwiriye ku buryo bunini bwo kuzura (kugeza kuri 10^5 cP), amazi atari ay’i Newtonia cyangwa ibikoresho birimo uduce duto.
o Yirinda ubushyuhe bwinshi cyangwa ahantu hakonje, bigatuma ibicuruzwa bihora bifite ubuziranenge bumwe.
o Ishobora gufata ibintu byoroheje bishobora gushonga cyangwa gushonga.
II. Gukoreshwa mu gutunganya Margarine
1. Uruhare rw'ingenzi mu ikorwa ry'umusaruro
Kugira ngo margarine ikoreshwe bisaba ko amavuta n'amazi bivangwa (amata, umunyu, ibivangwa, nibindi) bikurikirwa no gukonjesha vuba no gushushanya. Imashini ihindura ubushyuhe ku buso ikoreshwa cyane ni igikoresho cy'ingenzi, gikoreshwa cyane cyane muri ibi bikurikira:
o Gukonjesha no gushushanya emulsions: Gukonjesha vuba emulsions zivanze (hafi 40-50°C) kugeza kuri 10-20°C kugira ngo habeho imiterere ihamye ya kristale ya β' (ni ngombwa kugira ngo imiterere ibe yoroshye).
o Gutunganya nucleation: Imbaraga zo gukata za scrapers zisenya kristu nini, zigakora urusobe rw'ibinure rwiza kandi rungana, bikongera ubushobozi bwa cream bwo kwaguka.
o Uburyo bwo kuvura indwara yo kwisiga: Mu buryo bumwe na bumwe, amakoti akoresha ubushyuhe bwinshi akoreshwa mu gihe gito cyo kwisiga (urugero, 85°C mu gihe cy'amasegonda 15).
2. Guhuza n'imikorere y'inganda
o Kugenzura ubushyuhe neza: Guhindura ibinure bikoresha ubushyuhe cyane (urugero: amavuta y'amapamu agomba kugenzurwa kuri dogere selisiyusi 20-25), kandi icyuma gihindura ubushyuhe cyakuweho gishobora kugumana ubushyuhe neza.
o Kurinda gutandukanya ibice: Imbaraga nyinshi zo gukata amazi zituma igice cy'amazi gikwirakwira kimwe, birinda gutandukanya amavuta n'amazi.
o Gufata ibikoresho birimo ibinure byinshi: Margarine irimo ibinure biri hagati ya 70-80%, kandi imiterere y'imashini ikuraho ikibazo cyo kuziba kw'ibikoresho bisanzwe bihindura ubushyuhe.
3. Ibipimo bisanzwe by'ibikoresho
o Igipimo cyo kohereza ubushyuhe: 500-1500 W/(m²·K) (biterwa n'ubushyuhe bw'ibikoresho).
o Igipimo cy'ubukonje: Kugeza kuri 30°C/umunota (ni ingenzi mu gutuma ibinure bihinduka).
o Ubushobozi: Ibikoresho byo mu nganda bishobora gutwara toni 1-10 mu isaha.
III. Kugereranya n'izindi mashini zihindura ubushyuhe
Uburyo bwo gukoresha margarine ★★★★★ ★★☆ ★☆☆
| Ibiranga | Igikoresho cyo guhindurira ubushyuhe ku buso gikozwe mu buryo bwa "Scraped" | Igikoresho cyo guhindura ubushyuhe mu gikoresho n'umuyoboro | Umuvuduko w'ubushyuhe bw'isahani |
| Uburemere bukoreshwa | Hejuru (≤10^5 cP) | Iringaniye-hasi (≤10^3 cP) | Hasi (≤10^2 cP) |
| Ingaruka z'umwanda | Hafi cyane (kwisukura ukoresheje gukaraba) | Hejuru | Iringaniye |
| Ingaruka zo gukata | Irakomeye (irashobora kugenzurwa) | Intege nke | Intege nke |
IV. Inzira zo guteza imbere inganda
• Gukoresha neza ingufu: Koresha moteri zihindura frequency kugira ngo uhindure umuvuduko wa scraper, uhuze n'ibisabwa bitandukanye (urugero, gukata cyane ku mavuta make).
• Igenzura ry’ubwenge: Shyiramo ibikoresho by’ubushyuhe n’ubukonje kugira ngo uhindure igipimo cyo gukonjesha no gukata imbaraga mu gihe nyacyo. • Imiterere y’isuku: Ikurikije amahame ya EHEDG/3A, sisitemu ya CIP (Clean-In-Place) igabanya igihe cyo kudakora.
Imashini ihindura ubushyuhe, ifite ubushobozi bwo kohereza ubushyuhe no kuvanga neza, yabaye ibikoresho by'ingenzi mu nganda za margarine. Cyane cyane bitewe n'icyerekezo cyo gushaka ibinure bike kandi bifite imikorere myinshi, ibyiza byayo byo gutunganya neza bizagaragara cyane.
