Dispela'vacuum fryer'em i wanpela nupela kain masin bilong prosesim ol helti kaikai, na as wok bilong en i stap long ol samting bilong bodi bilong 'low-pressure boiling point reduction. Dispela 'vacuum fryer' i no wankain olsem ol 'atmospheric pressure frying equipment', em i wok insait long wanpela 'closed vacuum environment', we inap long daunim tru 'boiling point' bilong wara na oil bilong kaikai.
Long 'vacuum state' we 'vacuum fryer' i kamapim, 'boiling point' bilong wara i save pundaun long 100 digri long nomol presa i go long 80-110 digri. Dispela i mekim na 'vacuum fryer' inap long pinisim wok bilong rausim wara na praim ol kaikai long liklik hat tasol. Taim ol i praim long liklik hat tasol, dispela inap long abrusim 'oxidation' bilong 'edible oil' na 'decomposition' bilong ol 'nutritional components' bilong ol 'raw materials', na daunim wok bilong kamapim ol samting nogut olsem 'acrylamide'.
Taim 'vacuum fryer' i wok, 'vacuum system' i save kisim win na wara steam long 'frying chamber' bilong holim gutpela 'negative pressure' envairomen. Sistem bilong hatim haus i save givim wankain 'low-temperature hat eneji long mekim ol 'raw materials' i stap wankain. Dispela 'matching deoiling system' inap long rausim planti oil antap long ol samting we ol i wokim pinis, na dispela i mekim na i no gat planti oil na i gutpela long praim.
Dispela narakain wok prinsipel i mekim 'vacuum fryer' i kamap nambawan samting bilong wokim ol gutpela kaikai, we i stretim gut ol hevi bilong helt we i save kamap taim ol i save praim long bikpela hat.
