-Food Service Industry: FD Vegetables, FD Herbs, FD Meats
-Health & Nutrition: FD Culture Products, FD Instant Fruit Powder (smoothie additives)
-Emergency & Survival Food: FD Milk Products, FD Meats, FD Egg Products
The alternative vapor trap FD system operates through a three-stage process:
-Freezing Phase: The material is rapidly cooled to sub-zero temperatures, solidifying free and bound water to preserve structural integrity.
-Primary Drying (Sublimation): Under high vacuum, controlled heating enables ice sublimation, with vapor captured via desiccants or adsorption traps instead of a conventional condenser.
-Secondary Drying (Desorption): Residual moisture is removed at elevated temperatures, yielding a stable, porous product with minimal thermal degradation.

FAQ
What are the Vauum freeze dryer categories?
| Type | Key Feature | Available Sizes |
| Industrial Freeze Dryer | Internal vapor trap + dual condensers | A50, A75, A100, A125, A200 |
| Pilot Freeze Dryer | Single condenser (compact) | A5, A10, A20, A30 |
Retains nutrients: Freeze-dried food retains up to 97% of its nutrients, including vitamins, minerals, and antioxidants. Long shelf life: Freeze-drying removes the potential for bacterial growth, so freeze-dried food can last for years. Maintains flavor and texture: Freeze-drying preserves the original shape, flavor, and texture of food. Sustainable: Freeze-drying reduces food waste and transportation and storage costs.
Freeze drying works by first freezing a substance, then lowering the pressure around it to a vacuum, which allows the frozen water to directly transition from a solid (ice) to a gas (water vapor) through a process called sublimation, effectively removing the water content without going through a liquid phase, thus preserving the material's structure and properties; this is often used to preserve food, pharmaceuticals, and biological samples by significantly extending their shelf life.
