đ§ Which one should you choose?
-
Choose spray drying if:
You need low cost, large volumes, good flowability, and can tolerate some nutrient loss. -
Choose freeze drying if:
You need maximum bioactivity, flavor, aroma, or medicinal value, and cost is secondary.
In simple terms:
Spray-dried = efficient & economical
Freeze-dried = premium & protective
If you want, tell me your application (food, pharma, supplements, agriculture, cosmetics), and Iâll recommend the optimal drying method + parameters for it.
