Ol tropikel prut olsem mango, durian, dragon prut na passion prut em ol manmeri long wol i save laikim bikos ol i gat narakain swit na planti vaitamin. Tasol, bikpela suga, bikpela wara na hat i save mekim ol fres tropikel prut i save bagarap hariap tru, na dispela i save pasim ol long karim i go longwe na salim longpela taim. Olsem wanpela hai-teknoloji bilong lukautim kaikai, 'vacuum freeze-drying i save senisim tru hevi bilong prosesim ol tropikel prut, na wok bilong ol 'freeze-drying ikwipmen em i nambawan samting we i save makim kwaliti bilong laspela prodak.
As wok bilong ol masin bilong draim ol prut long ais-em i 'vacuum sublimation dehydration'. I no wankain olsem 'beking' na 'air-drying long bikpela hat, pastaim dispela masin i save ais hariap long ol nupela prut i go aninit long -30 digri long pasim wara insait long en i go insait long strongpela ais, na bihain em i kamapim wanpela 'high-vecuum envairomen, olsem na ais insait long prut i go antap stret long wara na i go aut long ol prut. Olgeta wok i pinis long liklik hat na liklik presa, we i abrusim bagarap bilong bikpela hat prosesing long ol vaitamin bilong prut, ol 'dietary fiber' na ol samting bilong smel.
Ol profesenel indastriel 'freeze-draing ikwipmen i gat tripela bikpela gutpela samting long prosesim ol tropikel prut. Namba wan, holim ful nutrisen. Ol sistem bilong kontrolim tempereja na 'vacuum' i save mekim na moa long 95% bilong ol 'original nutrients' bilong ol tropikel prut i stap yet, na dispela i winim tru pasin bilong draim ol prut. Namba tu, gutpela na strongpela tes. Yunifom sublimasen dehydresen i mekim ol prut tisyu i kamap porous na fluffy, wantaim wanpela krisp na non-stiki tes, na i no gat kollaps o strongim mit bilong prut. Namba tri, longpela laip. Bihain long ol profesenel 'freeze-drying ikwipmen prosesing, wara konten bilong ol tropikel prut i stap aninit long 5%, we i save pasim gut gro bilong ol baktiria, na laip bilong ol i ken kamap long 24 mun aninit long nomol tempereja siling kondisen.
Na tu, ol gutpela 'freeze-drying equipment inap long stretim ol samting bilong yu yet bihainim ol kain kain tropikel prut. Long ol prut we i gat planti suga olsem durian na litchi, dispela masin i ken stretim mak bilong ais na taim bilong sublimasen long abrusim suga i kamap kristal; long ol gutpela prut olsem mango na pitaya, em inap long stretim ol mak bilong 'vacuum degree' bilong mekim wara i lusim wara wankain. Apgret bilong eneji-seving na intelijen friz-ikwipmen bilong draim i no inap long mekim prodak i kamap gutpela moa, tasol tu i daunim entaprais yusim eneji na kos bilong wokman, na helpim ol prosesing entaprais long kamapim bikpela-skel, standet na hai-peliu prodaksen bilong ol tropikel prut.
