Fris draia, ol i kolim tu olsem lyophilizer, vekim fris draia o fris draia masin, em i wanpela spesel masin bilong rausim wara long bodi bilong ol kaikai we i save pilim hat tasol. Bikpela teknoloji bilong en long 'freeze-drying (lyophilization) em i narapela kain long 'oven drying', 'sun drying' na 'hot air dehydration'.
Maski bench-top fris draia bilong lab tes o indastriel fris draia bilong mas prodaksen, olgeta fris-drai na lyophilization operesen i bruk i go long tripela fiks link: pre-frising, praimeri sublimasen drai na sekenderi desorpsen drai.
Long taim bilong ais pastaim, masin bilong draim ais i save ais hariap long fri wara insait long ol prut na fres mit i go insait long strongpela ais long liklik tempereja. Taim ol i mekim kaikai i kamap ais olgeta, dispela i save pasim wara long brukim ol 'fiber tissue' bilong kaikai, na dispela em i samting ol i mas mekim pastaim long kamapim ol gutpela prodak bilong 'lyophilization'.
Praimeri sublimasen drai em i as wok bilong 'vacuum freeze dryer'. Aninit long wanpela klostu hai-vekim envairomen, strongpela ais insait long ol kaikai raw materiel i save go antap stret long wara steam na i save go aut. Indastrial lyophilizer i gat strongpela pamping kapasiti long mekim bikpela -efisiens mas friz-draiing.
Sekenderi 'desorption drying' i save rausim ol wara i stap yet we i stap insait long 'food fiber'. Gutpela tempereja kontrol sistem bilong 'freeze dryer' i save hatim ol samting isi isi long mekim ol i kamap drai na mekim ol prut, mit na kaikai bilong ol animal i drai long ais i stap longpela taim. Bench-top freeze dryer em i gutpela long stretim ol liklik 'sample parameters'.
Long pinisim, bikpela samting bilong 'freeze dryer' na 'lyophilizer' em long 'low-temperature vacuum dehydration. Friz-draim na 'lyophilization' i save holim ol 'natural nutrients' na 'original texture' bilong kaikai, olsem na dispela teknoloji i bosim ol bikpela indastri bilong wokim ol prut, mit na kaikai bilong ol animal.
