As for freeze drying, the cost is too expensive and higher, so not everyone can easily invest.

Currently, the use of freeze drying is most widely used by small and medium-sized food processing establishments and enterprises.

Especially for drying fruits that are characterized by a lot of water, a lot of sugar, and soft flesh such as mango, orange, apple, banana, dragon fruit, durian, kiwi,… and also suitable for pharmaceutical products. raw materials, nuts, fruits and vegetables, biodegradable vitamins,…
