Isishwankathelo:
Kwi-dryer esezantsi, isitshizi singena emoyeni oshushu kwaye sidlula kwigumbi kwicala elinye. Isitshizi siyaba ngumphunga ngokukhawuleza, kwaye ubushushu bomoya owomileyo buncitshiswa ngokukhawuleza ngokuphuphuma kwamanzi. Imveliso ayiyi kuthotywa i-thermal, kuba xa umxholo wamanzi ufikelela kwinqanaba elijoliswe kuyo, ukushisa kweengqungquthela akuyi kwandiswa kakhulu, kuba umoya ojikelezayo ngoku ubanda. Iimveliso zobisi kunye nezinye iimveliso zokutya ezingenwa bubushushu zezona zilungileyo kwindawo yokomisa ezantsi…
1.Kwisomisi esisezantsi
Isitshizi singena kumoya oshushu kwaye sidlula kwigumbi kwicala elinye. Isitshizi siyaba ngumphunga ngokukhawuleza, kwaye ubushushu bomoya owomileyo buncitshiswa ngokukhawuleza ngokuphuphuma kwamanzi. Imveliso ayiyi kuthotywa i-thermal, kuba xa umxholo wamanzi ufikelela kwinqanaba elijoliswe kuyo, ukushisa kweengqungquthela akuyi kwandiswa kakhulu, kuba umoya ojikelezayo ngoku ubanda. Iimveliso zobisi kunye nezinye iimveliso zokutya ezingevani nobushushu zezona zomiswe kakuhle kwiindawo ezomileyo ezisezantsi.
2.I-countercurrent dryer
Isomisi sokutshiza siyilelwe ukwazisa isitshizi kunye nomoya kuzo zombini iziphelo zesomisi, kwaye ungene emoyeni njengoko umlomo wombhobho ufakwe phezulu nasezantsi. Isomisi esichasene ne-countercurrent sinika ukuguquka kwamanzi ngokukhawuleza kunye nokusebenza kwamandla aphezulu kunoyilo lwangoku. Ngenxa yoqhagamshelwano phakathi kweengqungquthela ezomileyo kunye nomoya oshushu, olu luyilo alufanelekanga kwiimveliso ezishushu. Izixhobo zokomisa i-countercurrent ngokuqhelekileyo zisebenzisa imilomo ye-atomization, enokuthi ihambe emoyeni. Isepha kunye neesepha zihlala zisetyenziswa kwi-countercurrent dryers.
3.I-mixed-flow drying
Olu hlobo lwesomisi ludibanisa i-downcurrent kunye ne-countercurrent. Umoya we-mixed-flow dryer ungena kwimilomo ephezulu nangaphantsi. Ngokomzekelo, kwi-countercurrent design, i-mix-flow dryer yenza umoya oshushu weengqungquthela ezomileyo, ngoko ke uyilo alusetyenziswanga kwimveliso ye-thermal.
