The fruit is rich in nutrition, the dried fruit is delicious and the preservation time is long. During fruit drying process, in order to keep the nutrition and taste, fruit drying have to adpot vacuum drying technology to keep dried fruit natural and health. Nasan produce two different vacuum drying equipment for fruit, vacuum microwave fruit drying machine and vacuum freeze fruit drying machine.
● Fruit Vacuum Microwave Drying Machine
Vacuum microwave drying machine use middle temperature to dry fruit, the speed is very fast and energy cost is very low. Because the middle temperature drying without long time frozen, the tast and the color is very good. But after dried the fruit will reduce 10% dimension because the drying process is evaporation, nutrient will lost a little and could save 90%. Vacuum microwave drying equipment is suit to dry high request of color and taste fruit, it is a good quality and low cost vacuum drying technology.
● Fruit Vacuum Freeze Drying Machine
Vacuum freeze drying machine use low temperature to dry fruit, the speed is very slow and energy cost is very high. Because the most drying process is subzero temperature, the color and taste will become light and tasteless . But after dried the fruit will save 100% of the original dimension because the drying process is sublimation, nutrient will have very less loss and could save 95%. Vacuum freeze drying equipment is suit to dry high request of shape and nutrient fruit, it is a high quality with high cost vacuum drying technology.
