Ukomisa nge-spray dryer kwindawo yokuqala nto leyo ekhokelela ekubeni inamathele… Indlela yokulawula

Ukutya okomisiweyo ngokutshizwa kwahlulwe kubini: okunganamatheliyo nokunamathelayo. Izithako ezinganamatheliyo kulula ukuzitshiza ngoyilo olulula lokomisa kunye neempuphu zokugqibela ezihamba ngokukhululekileyo. Imizekelo yezinto ezingenakunamatheliyo ibandakanya amaqanda agutyiweyo, ubisi oluyimpuphu, i-maltodextrins ezifana nesisombululo, iintsini, kunye neeproteni. Kwimeko yokutya okunamathelayo, kukho iingxaki zokomisa phantsi kweemeko eziqhelekileyo zokomisa ngokutshizwa. Ukutya okunamathelayo kudla ngokunamathela eludongeni lokomisa okanye kube kukutya okunamathelayo okungenamsebenzi kwiindawo zokomisa nakwiinkqubo zothutho ezineengxaki zokusebenza kunye nemveliso ephantsi. Ukutya okuneswekile kunye ne-asidi yimizekelo eqhelekileyo.

Ukunamathela yinto eyenzeka ngexesha lokomiswa kwezinto zokutya ezifafazwa rhoqo ngeswekile kunye ne-asidi. I-Powder tack yipropati yokunamathela edibeneyo. Ingachazwa ngokwemigaqo yokunamathela kwe-particle-particle (ukubambisana) kunye nokunamathela kwi-particle-wall (ukunamathela). Umlinganiselo wamandla apho ii-particles ze-powder zibophana ngawo kungenxa yeempawu zayo zangaphakathi ezaziwa ngokuba yi-cohesion, zenze amaqhuma kwindawo yomgubo. Ke ngoko amandla afunekayo ukugqobhoza ii-agglomerates ze-powder kufuneka abe makhulu kunamandla adibeneyo. Ukunamathela yipropati yokudibanisa, ukuthambekela kwee-particles ze-powder ukunamathela kwiindonga zezixhobo zokomisa nge-spray. Ukunamathela kunye nokunamathela ziiparameter eziphambili kuyilo lweemeko zokomisa kunye nokomisa. Ukwakheka komphezulu wee-particles ze-powder ikakhulu kunoxanduva lwengxaki yokunamathela. Ukunamathela kunye nokunamathela kwezinto zomphezulu wee-particles ze-powder zahlukile. Ngenxa yokuba ukomisa kufuna inani elikhulu lokudluliselwa kwe-solute kumphezulu wee-particle, yi-bulk. Iimpawu ezimbini ezixineneyo (ukubambisana kunye nokunamathela) zinokuhlala kunye kwizinto zokutya ezomisiweyo nge-spray-rich sugar. Ukunamathelana phakathi kweesuntswana kukudibana kukwakheka kweebhulorho zolwelo ezizinzileyo, iibhulorho zolwelo ezihambayo, ukudibana koomatshini phakathi kweemolekyuli kunye nomxhuzulane we-electrostatic kunye neebhulorho eziqinileyo. Xa igumbi lomile, iisuntswana zomgubo wodonga zinamathela ikakhulu ngenxa yokulahleka kwezinto ezisetyenziswayo ekomiseni iswekile kunye nokutya okutyebileyo kwi-asidi. Izinto ezi-powdery xa zigcinwa ixesha elide eludongeni, ilahleko yokomisa.

Izizathu zokunamathela:

Ukubuyiswa komgubo wokomisa we-Spray Sugar kunye ne-Acid Rich Foods Driving Powder Ngokusebenzisa iteknoloji yokomisa nge-spray, iiswekile ezinobunzima obuphantsi be-molecular (i-glucose, i-fructose) kunye nee-organic acids (i-citric, i-malic, i-tartaric) zinzima kakhulu. Ukufunxwa kwamanzi aphezulu, i-thermoplasticity, kunye nobushushu obuphantsi be-transition yeglasi (i-Tg) ezi molekyuli zincinci zinegalelo kwingxaki yokunamathela. Amaqondo obushushu okomisa nge-spray angaphezu kwe-Tg 20°C, ezi zithako ikakhulu zenza amasuntswana athambileyo kwiindawo ezinamathelayo, nto leyo ebangela ukuba umgubo unamathele kwaye ugqibela unesakhiwo esifana ne-paste endaweni yomgubo. Ukuhamba okuphezulu kwe-molecular kwezi molekyuli kungenxa yobushushu bazo obuphantsi be-transition yeglasi (i-Tg), nto leyo ekhokelela kwiingxaki zokunamathela kumaqondo obushushu adla ngokuthandwa kwii-spray dryers. Ubushushu be-transition yeglasi luphawu oluphambili lobushushu be-transition yesigaba esingaguqukiyo. Isiganeko sokuguquka kweglasi senzeka xa iswekile eqinileyo, engaguqukiyo, iguquka ibe yi-raber ethambileyo, efana nolwelo. Amandla omphezulu, iglasi eqinileyo inamandla omphezulu aphantsi kwaye ayinamatheli kwiindawo eziqinileyo ezingenamandla aphantsi. Ngenxa yotshintsho oluvela kwimeko yeglasi ukuya kwimeko yerabha (okanye ulwelo), umphezulu wezinto ezibonakalayo unokuphakama, kwaye ukusebenzisana kwemolekyuli kunye nomphezulu oqinileyo kunokuqala. Kwinkqubo yokomisa ukutya, imveliso ikwimeko yolwelo okanye yokubophelela, kwaye ngenxa yokususwa kwe-plasticizer (amanzi) imveliso yokutya yolwelo/ebophelelekileyo iba yimeko yeglasi. Izinto zokutya ziya kuhlala zinamandla aphezulu ukuba imveliso yokutya ayitshintshi ukusuka kubushushu obuphezulu bokomisa kunokutshintsha kobushushu be-vitrification. Ukuba le mveliso yokutya idibana nomphezulu oqinileyo onamandla aphezulu iya kunamathela okanye inamathele kuwo.

Ukulawula ukuxinana:

Kukho iindlela ezininzi zesayensi yezinto kunye neendlela ezisekelwe kwinkqubo zokunciphisa i-viscosity. Iindlela ezisekelwe kwisayensi yezinto ziquka izongezo zokomisa ulwelo zezinto ezinobunzima obukhulu be-molecular ukuphakamisa ubushushu ngaphaya kotshintsho lweglasi, kwaye iindlela ezisekelwe kwinkqubo ziquka iindonga, amazantsi, njl.njl. zamagumbi oomatshini.
