Machine For Drying Fruits--freeze Dryer VS Dehydrator

Fruits are the most natural and healthy food, rich in vitamins, minerals, and plant fiber. There are various machine for drying fruits and preserving / processing fruits. The common processing methods include canned fruit, freeze dried fruit, dehydrated fruit. Although they can both extend the shelf life of fruits and provide convenient ways of consumption, they have different characteristics and techniques. So what machine for drying fruits is best? freeze dryer VS dehydrator, what’s the difference?

I. What are the most common dried fruit?

There are many dried fruit on the market, while the most valued and popular dried fruti includes: dry figs, dry apricots, prunes, raisins, goji berries, dry cranberries, dry mango, dry plum, dehydrating apples, dry strawberry, dry dates, etc.

II. What’s the different between freeze dried fruit VS dehydrated fruit?

There are much difference between freeze dried fruit and dehydrated fruit. You can tell clearly from the appearance, shape, color. Freeze dried fruit keep amost the original shape, color, and nurtient, while the machine freeze dryer cost and running cost is much higher than dehydrator, so the freeze dried fruit price is much higher than dehydrated fruits.

Take dehydrated figs VS freeze dried figs for compare:

III. How to freeze dry fruits?

Machine for drying fruits: freeze dry machine, full name is vacuum freeze dry machine, which freeze fruits at temperatures above -40 degrees Celsius and undergoes sublimation and dehydration. The vacuum environment reduces the oxidation of fruits and preserves over 95% of the nutrients in the fruits.

Cutting the fruit into appropriate sized blocks or thin slices, and then freezing the water in the fruit at low temperatures to freeze. Next, in a vacuum environment, the dehydration temperature is gradually increased to convert ice into water vapor, thereby separating the water in the fruit and ultimately obtaining the freeze-dried product of the fruit.

Freeze dried fruits retain the vitamins, minerals, and other nutrients in the fruit. In addition, freeze dried fruits have a longer shelf life and can be stored for a longer period of time.

IV. How to dry fruits with dehydrator?

Cutting the fruit into blocks or thin slices and placing them in industrial dehydrator machine. The industrial dehydrator machine uses heating equipment to generate hot air, which evaporates the water in the fruit, thereby achieving the effect of dehydration. The drying time and temperature often vary depending on the type and size of the fruit.

The advantages of industrial dehydrator machine are fast speed and high efficiency. Compared to freeze dry and air drying, the drying time is much shorter. In addition, dehydrating makes the taste stronger, making it more suitable for consumers who prefer a unique taste. However, the dehydrating process usually requires a higher temperature, which may result in the loss of nutrients in some fruits, especially substances such as vitamin C that are easily damaged by heat.

V. Machine for drying fruits

1.Machine for drying fruits — fruit cleaner machine: Use the fruit cleaner machine to remove impurities and dust from the surface of the fruit. 2. Machine for drying fruits — Fruit peeler machine: remove the peel, core of the fruits. Most of the fruits need to peeled first, such as apple, pineapple, mango etc. There are different fruit peeler machine for different kinds, different size fruits.
