Vacuum Vegetable Freeze Dryer Machine is used to dry vegetable with high drying quality. Freeze Dryer can make the vegetable retain biological activity and no damage to the vegetable nutrition. These Freeze Drying Vegetables also have good taste, color and appearance and easy to keep Longer shelf-life
Working Principle of Vegetable Freeze Dryer
In a sealed vacuum, by heating the frozen material, the ice in the frozen material will be sublimated to a continuously frozen vapor condenser. After a period of time, the material is dried, the water is moved to vapor condenser of the freeze dryer.
Why Use Freeze Drying
When you read the article, you’ve got half of the success. Freeze drying food is a new business, even you cannot see any freeze-dried fruits snacks or powder in big food exhibition. But it would be the trend of the development of dried food in the future, as the freeze-dried product is nutritional, natural and healthy food.
Advantage of Freeze-Dried Vegetable
1, Retain biological activity
To retain biological activity as much as possible, the material must be in low temperature, but on the contrary, drying needs heat involved. Heating will destroy biological activity and nutrition. Our solution is to get the liquid water in the material completely frozen to solid status. The water in the material is solid ice status during the whole heating processing till the material is completely dried. So, the biological activity is retained greatly.
2, No damage to the nutrition
Heating is no doubt the main reason of nutrition damage. By using our freeze dryer, heating processing occurs after material gets completely frozen to ice status. Thus, it typically retains 97% of the nutritional value.
3, Taste, color and appearance
Lyophilized by our freeze dryer, the food material still tastes fresh, delicious as a snack, but a different try. The freeze-dried material remains the same color, flavor and appearance as it was first harvested. And the volume of freeze-dried material has no change, that is to say, the appearance has no shrink or toughen. It is the real high quality preserved food.
4, Longer shelf-life
Freeze dried material has a longer preservation time than frozen, canned and oven dried items. Freeze dried food is really healthy, you will be far away from pigment, additive, GMO and anti-season food material.
