Ngwá ọrụ emulsifying
Isi ihe eji arụ ọrụ maka ịkwadebe emulsion bụ igwe emulsifying, nke bụ ụdị emulsifying akụrụngwa maka ịgwakọta mmanụ na mmiri n'otu n'otu. Ka ọ dị ugbu a, e nwere ụdị igwe emulsifying atọ: igwe igwe emulsifying, igwe igwe colloid na homogenizer. Emulsifying igwe ụdị na Ọdịdị, arụmọrụ na size nke emulsion ahụ (dispersion) na àgwà nke emulsion (nkwụsi ike) nwere nnukwu mmekọrịta. N'ozuzu, dị ka ugbu a n'ọtụtụ ebe ji ntecha factory akpali emulsifier, na emulsion mepụtara ogbenye dispersion. The ahụ bụ nnukwu na keadighi rarii, na ogbenye nkwụsi ike na mfe mmetọ. Ma mmepụta ya dị mfe, ọnụahịa ahụ dị ọnụ ala, ọ bụrụhaala na ị na-aṅa ntị na nhazi ezi uche nke igwe ahụ, jiri ya mee ihe n'ụzọ kwesịrị ekwesị, ma nwee ike ịmepụta n'ozuzu ihe mejupụtara àgwà nke ihe ịchọ mma na-ewu ewu. Colloid igwe ihe na homogenizer bụ mma emulsifying akụrụngwa. Na-adịbeghị anya, emulsifying igwe emewo nnukwu ọganihu, dị ka agụụ emulsifying igwe, na emulsion kwadebere site dispersion na kwụsie ike nke magburu onwe ya.
Ọnọdụ okpomọkụ
Okpomọkụ emulsification nwere mmetụta dị ukwuu na emulsification, mana enweghị oke oke na okpomọkụ. Ọ bụrụ na mmanụ na mmiri bụ mmiri mmiri, ha nwere ike emulsified site na-akpalite na ụlọ okpomọkụ. N'ozuzu, emulsification okpomọkụ na-adabere n'ebe agbaze nke ihe ndị nwere nnukwu agbaze na akụkụ abụọ ahụ, na ihe ndị dị ka ụdị emulsifier na solubility nke mmanụ mmanụ na mmiri mmiri kwesịrị ịtụle. Na mgbakwunye, a ga-edobe okpomọkụ nke akụkụ abụọ ahụ ihe fọrọ nke nta ka ọ bụrụ otu, karịsịa maka ihe ndị na-emepụta ihe na abụba nwere ebe mgbaze dị elu (n'elu 70 ℃), mgbe emulsifying, a ghaghị ịgbakwunye usoro mmiri dị ala, iji mee gbochie wax na abụba si crystallizing si tupu emulsification, dapụtara na oke ma ọ bụ keadighi rarii na emulsion na-enweghị isi. N'ikwu okwu n'ozuzu, mgbe emulsifying, okpomọkụ nke mmanụ na mmiri nwere ike ịchịkwa n'etiti 75 ℃ na 85 ℃. Ọ bụrụ na oge mmanụ nwere nnukwu ihe mgbaze na ihe ndị ọzọ, okpomọkụ emulsifying ga-adị elu n'oge a. Na mgbakwunye, ọ bụrụ na viscosity na-abawanye nke ukwuu na usoro emulsification, nke a na-akpọ oke oke ma na-emetụta ngwakọta ahụ, ụfọdụ okpomọkụ emulsification nwere ike ịmalite n'ụzọ kwesịrị ekwesị. Ọ bụrụ na emulsifier eji nwere ọnọdụ mgbanwe oge ụfọdụ, a na-ahọrọ okpomoku emulsifying n'akụkụ okpomọkụ mgbanwe oge. Emulsification okpomọkụ mgbe ụfọdụ na-emetụta urughuru size nke emulsion. Ọ bụrụ na a na-ejikarị emulsifier anionic nke fatty acid ncha, nha nke emulsion bụ ihe dịka 1.8-2.0μm mgbe a na-achịkwa okpomọkụ emulsification na 80 ℃. Ọ bụrụ na urughuru size bụ banyere 6μm mgbe emulsification na-rụrụ na 60 ℃. Mmetụta nke emulsification okpomọkụ na urughuru size adịghị ike mgbe na-abụghị ionic emulsifier na-eji maka emulsification.
Emulsifying oge
Emulsification oge doro anya na-enwe mmetụta na àgwà nke emulsion, na mkpebi siri ike nke emulsifying oge bụ dị ka olu ruru nke mmanụ frasi mmiri na-adọ, abụọ na-adọ viscosity na igbanye viscosity nke emulsion, ụdị na onunu ogwu nke emulsifier, emulsifying. okpomọkụ, emulsifying oge ole, zuru ezu iji mee ka usoro nke emulsification, na-ejikọta ya na arụmọrụ nke emulsification ngwá ọrụ, oge emulsification. nwere ike kpebisie ike dị ka ahụmahụ na nnwale.
