Commercial freeze drying equipment, also known as industrial lyophilizers, is used to remove moisture from products by freezing them and then reducing surrounding pressure to allow the frozen water to sublimate directly into vapor. This process retains the product’s shape, nutrients, flavor, and chemical composition.
This industrial freeze dryer is used across a wide range of industries where moisture-sensitive products require preservation without compromising quality.
Q1: What is the difference between vacuum drying and freeze drying? Vacuum drying uses heat under vacuum; freeze drying uses sublimation at low temperatures, preserving structure and bioactivity.
Q2: How long does a freeze drying cycle take? Typically 12–36 hours, depending on product thickness, moisture, and system design.
Q3: Can I freeze dry liquids? Yes—liquids like soups or extracts can be pre-frozen in trays or vials for batch drying.
Q4: Is freeze drying better than air drying? Absolutely—for sensitive materials like food, enzymes, or pharmaceuticals, freeze drying maintains superior quality.
Q5: How much space does a commercial freeze dryer need? Depends on size. Small units may need 2–5 m², while large industrial systems may require over 20 m².
