Kwezi zityalo, ukomiswa komkhenkce yindlela esebenzayo yoxinaniso kunye nokugcinwa. Nangona kunjalo, ezinye izityalo zifuna ubushushu obuthile ukususa ubuthi. Kwezi zityalo, iteknoloji yokumisa isitshizi ifanelekile. Thatha iimbotyi zesoya njengomzekelo. Inkqubo yoxinaniso ifuna ubushushu obuthile ukuze kususwe into ebizwa ngokuba yi-trypsin inhibitors (eya kuthi ithintele ukugaywa kunye nokubola kweprotheyini).

Ukutshiza ukomisa kudla ngokuba linyathelo lokugqibela kwinkqubo yokwenziwa kwemveliso, kukutshintsha izinto ukusuka kulwelo ukuya kumgubo ngokutshiza ngokuqhubekayo, ukuxuba kunye nokomisa. Phakathi kweetekhnoloji ezininzi zokugcina ukutya, ukomisa isitshizi kuneenzuzo zakho ezizodwa. Ngenxa yokuba iqondo lobushushu elisetyenziswe kule teknoloji aliphezulu kakhulu, linokugcina ngokufanelekileyo incasa, umbala, kunye nesondlo sokutya ngelixa isusa ungcoliseko lwe-microbial. Ukutshiza ukomisa ngokuqhelekileyo kusetyenziselwa ukususa amanzi kwimathiriyeli ekrwada. Ukongeza, inokusebenzisa ezinye izinto ezahlukeneyo, ezinjengokutshintsha ubungakanani, imilo, okanye ukuxinana kwezinto. Inokunceda ekongezeni ezinye izithako ngexesha lenkqubo yokuvelisa, inceda ukuvelisa iimveliso ezinemigangatho engqongqo yomgangatho. Ukusetyenziswa kwendlela yokumisa isitshizi Phambi kokutshiza komiswe, iimbotyi zesoya kufuneka zihlanjwe kwaye zixotyulwe, kwaye izithako ezingezizo iiproteni ezifana namafutha kufuneka zicuthwe, ukuze kugxininiswe ezona zithako zinezondlo kwiimbotyi zesoya. Emva koxinzelelo olunjalo, iimbotyi zesoya zinokutshizwa zomiswe.

Eyona nkqubo yokomisa isitshizi inokwahlulwa ibe ngamanyathelo aliqela:

Okokuqala, imveliso elulwelo yondliwa kwiatomizer, apho ivili elijikelezayo elinesantya esiphezulu litshintsha i-atomize ulwelo, nto leyo ebangela ukuba imveliso ibe yimeko yolwelo oluqinileyo oluxubeneyo.

Kwinqanaba lesibini, iinqununu ze-atom zijoliswe kwigumbi lokumisa elinokushisa okulawulekayo kunye nokuhamba komoya, kwaye umoya oshushu ukhupha ulwelo kwiincinci. Ukuze imveliso yokugqibela ihlangabezane nemigangatho, ixesha lokuqhagamshelana leengqungquthela ezinomoya oshushu kufuneka lifaneleke ukugcina inani elithile lomswakama kwimveliso ye powder; Ngexesha elifanayo, urhulumente kwigumbi lokumisa kufuneka kwakhona ulawulwe kakuhle, njengoko ubukhulu bomthamo wegumbi lokumisa kunye neemeko zokuhamba komoya kunokuchaphazela ukondla kwemveliso.

Isinyathelo sesithathu kunye nesokugqibela kwiprogram yonke kukuqokelela umgubo kwi-airflow kwi-container ngokusebenzisa isahluli, ukwenzela ukuba imveliso yokugqibela ihlanganiswe okanye ixutywe namanye amacandelo.

Iimbonakalo:Isantya sokumisa ngokukhawuleza. Emva kokutshiza kwe-centrifugal, indawo ephezulu yolwelo lokutya yanda kakhulu. Kwiqondo eliphezulu lobushushu bomoya, i-95% - 98% yamanzi inokuthi ibe ngumphunga ngokukhawuleza, kwaye ixesha lokumisa liyimizuzwana embalwa kuphela. I-parallel flow flow spray drying inokwenza amathontsi ahambe kwicala elinye nomoya oshushu. Nangona iqondo lokushisa lomoya oshushu liphezulu, umoya oshushu ungena kwigumbi lokumisa kwaye ngokukhawuleza uqhagamshelane namathontsi okutshiza, okukhokelela ekuhlahleni okubukhali kwamaqondo obushushu angaphakathi, ngelixa iqondo lobushushu bebhalbhu emanzi yezixhobo aluguquguqukiyo, ngoko ke kufanelekile ukomisa izinto ezishushu.
