How Freeze Drying Works
Freeze drying, or lyophilization, involves three main stages: freezing, primary drying, and secondary drying. Initially, food is frozen to solidify its moisture. During primary drying, pressure is lowered, and heat is applied, allowing ice to sublimate directly into vapor. In secondary drying, any remaining moisture is removed to enhance shelf life. This process effectively preserves 90%-95% of the food’s nutrients, making freeze-dried foods a healthier choice compared to dehydrated or canned options.
Benefits of Using a Freeze Dry Machine
Using a home freeze dryer offers numerous benefits:
- Nutritional Retention: Freeze-dried foods maintain most of their original nutrition, flavor, and texture.
- Long Shelf Life: Properly freeze-dried foods can last 25 years or more without refrigeration.
- Versatility: Suitable for a variety of foods, including fruits, vegetables, meats, and complete meals.
- Cost-Effective: Buying and preserving bulk food can save money in the long run.
- Emergency Preparedness: Freeze-dried foods are ideal for survival kits, ensuring you’re prepared for any situation.
