Tshiza ukomisa isomisi ekuqaleni nto leyo ekhokelela ekuncangathi… Ukulawula njani

Ukutya okutshiziweyo kuluhlu olubini: okungancangathi kunye nokuncangathi. Izithako ezingancangathi kulula ukutshiza zomile ngoyilo olulula lwesomisi kunye nomgubo oqukuqelayo okhululekileyo wokugqibela. Imizekelo yezinto ezingabonakaliyo zibandakanya amaqanda omgubo, ubisi olungumgubo, i-maltodextrins njengesisombululo, iintsini, kunye neeprotheni. Kwimeko yokutya okuncangathi, kukho iingxaki zokomisa phantsi kweemeko eziqhelekileyo zokumisa isitshizi. Ukutya okuncangathi kudla ngokunamathela kwiindonga zokomisa okanye kube kukutya okuncangathi okungenamsebenzi kumagumbi okomisa kunye neenkqubo zothutho ezineengxaki zokusebenza kunye nezivuno ezisezantsi zemveliso. Iswekile kunye nokutya okuneasidi yimizekelo eqhelekileyo.

Ukuncamathela yinto eyenzeka ngexesha lokomiswa kwemathiriyeli yokutya etyetyisiweyo ngeswekile kunye ne-asidi ehlala itshizwa rhoqo. I-powder tack yipropati edibeneyo yokubambelela. Inokuchazwa ngokuhambelana ne-particle-particle adhesion (ukubambisana) kunye ne-particle-wall adhesion (adhesion). Umlinganiselo wamandla apho amasuntswana omgubo abophe ngawo ngenxa yeempawu zayo zangaphakathi ezibizwa ngokuba yi-cohesion, ezenza izigaqa kwibhedi engumgubo. Ngoko ke amandla afunekayo ukutyhutyha i-agglomerates yomgubo kufuneka ibe mkhulu kune-cohesive force. I-Adhesion yipropati edibeneyo, ukuthambekela kwe-powder particles ukunamathela kwiindonga zesixhobo sokumisa isitshizi. Ubumbano kunye nokubambelela kwiiparameters eziphambili ekuyilweni kweemeko zokumisa nokomisa. Ukubunjwa komphezulu we-powder particles ikakhulu uxanduva lwengxaki yokubambelela. Ukuqhelana kunye nokubambelela kwi-powder particle surface izinto ziyahluka. Ngenxa yokuba ukomisa kufuna inani elikhulu lokudluliselwa kwe-solute kwi-particle surface, ininzi. Iimpawu ezimbini ze-viscous (ubumbano kunye nokubambelela) zinokuhlalisana kwizinto zokutya ezinoshukela ezitshisiweyo. Ukuncamathela phakathi kwamasuntswana kukumanyana kukubunjwa kweebhulorho ezingamanzi ezisisigxina, iibhulorho ezingamanzi ezihambayo, ukudibanisa ngoomatshini phakathi kweemolekyuli kunye nomxhuzulane we-electrostatic kunye neebhulorho eziqinileyo. Ngegumbi lokomisa amasuntswana omgubo wodonga ancamathele ikakhulu ngenxa yokulahleka kwezinto ekomisweni kokutshiza kweswekile kunye nokutya okutyebileyo kweasidi. Izinto zomgubo xa zigcinwe ixesha elide kwilahleko yokomisa eludongeni.

Izizathu zokuncamathela:

Ukutshiza iSugar kunye ne-Acid Rich Foods Drying Powder Recovery Ukusebenzisa iteknoloji yokumisa isitshizi, ishukela eliphantsi le-molecular weight (i-glucose, i-fructose) kunye ne-organic acids (i-citric, i-malic, i-tartaric) inzima kakhulu. Ukufunxwa kwamanzi aphezulu, i-thermoplasticity, kunye nobushushu obuphantsi beglasi yokutshintsha (Tg) ezi molekyuli zincinci zinegalelo kwingxaki yokuncamathela. Tshiza ubushushu bomileyo obungaphezulu kwe-Tg 20°C, ezi zithako zenza amasuntswana athambileyo kwindawo encangathi, nto leyo ebangela ukuba umgubo uncamathele kwaye uphele nesakhiwo esifana nencama endaweni yomgubo. Ukushukuma okuphezulu kweemolekyuli ezinjalo kungenxa yobushushu obusezantsi beglasi (Tg), nto leyo ekhokelela kwiingxaki zokuncamathela kumaqondo obushushu adla ngokuthandwa kwizitshizi zomisi. Iqondo lokushisa lokutshintsha kweglasi luphawu oluphambili lobushushu besigaba se-amorphous. Isiganeko senguqu yeglasi senzeka xa iswekile eqinileyo eqinileyo, i-amorphous, ifumana inguqu kwirubha ethambileyo, isigaba solwelo. Amandla omphezulu, iglasi eqinileyo inamandla asezantsi kwaye ayihambelani nemiphezulu eqinileyo ene-eneji esezantsi. Njengomphumo wenguqu ukusuka kwi-glass state ukuya kwi-rubbery (okanye i-liquid) i-state, indawo yezinto eziphathekayo inokuphakanyiswa, kwaye i-molecular and solid surface interactions ingaqala. Kwinkqubo yokomisa ukutya, imveliso ikwimeko engamanzi okanye ebotshiweyo, kwaye ngenxa yokukhutshwa kweplasticizer (amanzi) imveliso yokutya engamanzi / ebotshiweyo iba yimeko yeglasi. Izinto zokutya ziya kuhlala ziphezulu amandla e-viscous ukuba imveliso yokutya ayitshintshi ukusuka kwiqondo lokushisa eliphezulu lokumisa kunokutshintsha kwiqondo lokushisa kwe-vitrification. Ukuba le mveliso yokutya idibene nomgangatho oqinileyo onamandla amakhulu iya kubambelela okanye ibambelele kuyo.

Ukulawula iViscosity:

Kukho inani lezinto zesayensi kunye neendlela ezisekelwe kwinkqubo yokunciphisa i-viscosity. Izinto ezisekelwe kwiindlela zenzululwazi zibandakanya izinto ezinobunzima bemolekyuli eziphezulu zolwelo ezongeziweyo zokomisa ukunyusa iqondo lobushushu ngaphaya kotshintsho lweglasi, kunye neendlela ezisekelwe kwinkqubo ziquka iindonga, umzantsi, njl njl. yamagumbi oomatshini.
