How to freeze-dry spinach? As a leafy green vegetable, spinach requires the same freeze-drying method as other leafy greens, using radiation-based freeze-drying equipment.

Because spinach leaves have gaps between their leaves, they appear fluffy. Therefore, they cannot transfer heat or cold to a heat source through direct contact. Spinach freeze-dryers rely on space or close-range radiation conduction as the only alternative.

What are the steps for freeze-drying spinach?

Step 1: Wash the spinach and sterilize with ozone.

Step 2: Drain the washed spinach.

Step 3: Place the drained spinach on a plate.

Step 4: Freeze the spinach in the freeze-dryer or in a quick-freeze room to -30°C.

Step 4: Sublimation-dry the frozen spinach.

Step 5: After a period of sublimation, the spinach is freeze-dried.

Step 6: Discharge the freeze-dried spinach.

Step 7: Package the freeze-dried spinach.
