Precision Workflow for Consistent Quality
Our freeze dry fruit machine leverage the fundamental principle of water sublimation – transforming ice directly into vapor under controlled vacuum. This sophisticated process ensures minimal damage to your valuable fruit products.
Preparation: Load fruit (≤10mm thickness) onto trays and position the temperature sensor.
Pre-Freezing: Place loaded trays onto the shelves. Critical to final product quality, you choose between slow freezing (for larger crystal structure) or rapid freezing (for smaller crystals), depending on your specific fruit and desired texture.
Vacuum & Sublimation: Seal the chamber, activate the cold trap refrigeration. Once the cold trap hits -80°C, initiate vacuum pumping. When pressure falls below 10 Pa, sublimation drying begins. We provide precise controls to manage shelf temperature below your product's critical eutectic point during this phase.
Desorption Drying: For final moisture removal, secondary drying parameters are carefully set, ensuring temperatures stay below the product's denaturation or decomposition point.
Completion: Water vapor is efficiently captured by the cold trap, resulting in perfectly dried, shelf-stable fruit.
Robust Construction & Key Components
Every unit integrates essential systems for peak performance:
- Efficient Pre-freezing Chamber: Rapidly brings fruit below freezing point.
- Sealed Vacuum Drying Chamber: Maintains the low-pressure environment essential for sublimation.
- High-Capacity Condenser (Cold Trap): Effectively captures sublimated vapor, preventing reabsorption.
- Controlled Heating System: Provides the precise energy needed for sublimation and desorption.
- Reliable Vacuum Pump: Maintains and controls the critical vacuum levels throughout the cycle.
- Intuitive Control System: Ensures precise management of the entire freeze-drying process.
Why Choose Our Freeze Dry Fruit Machine?
- Maximum Nutrient Retention: Low-temperature processing safeguards vitamins, minerals, and enzymes destroyed by conventional heat drying.
