Vacuum Freeze Dryer

Preserve 95% Nutrition with Lyophilization

Vacuum-Fresh vacuum freeze dryers (lyophilizers) use vacuum freeze-drying technology to remove moisture from materials by sublimation under low-temperature vacuum conditions, completely preserving the color, aroma, nutrients, and shape of the original material.

Why Choose Freeze Drying?

Nutrient Retention	40-60%	50-70%	≥95%
Color Restoration	Poor	Fair	Excellent
Rehydration Time	Long	Medium	Very Fast (<3 min)
Shelf Life	6-12 months	12-18 months	24-36 months

Key Advantages

① Zero Nutritional Damage Freeze drying operates at -40°C to -10°C, preserving heat-sensitive substances (Vitamin C, probiotics, active ingredients) completely.

② Industry-Leading Energy Efficiency Vacuum-Fresh freeze dryers feature multi-stage waste heat recovery, saving 18-22% energy vs. conventional units. Based on 300 operating days/year, annual electricity savings ≈ $4,500.

③ Intelligent Control
