Advantages of Alternative Vapor Trap Systems for 100㎡ Vacuum lyophilizer
1.Right Condenser of 100㎡ Vacuum lyophilizer Ice Melting Phase:
The sealing door plate moves from the left to the right, closing off the right condenser,and the left condenser remains open to the chamber, capturing water vapor from the material.
The de-icing tank applies negative pressure to the closed right condenser, pulling in vapor to melt the collected ice.Melted ice (water) drains through a lower pipeline into the de-icing tank.
2.Left Condenser of 100㎡ Vacuum lyophilizer Ice Melting Phase:
After the right condenser is de-iced, the door plate shifts back to the left, closing the left condenser.
The right condenser reopens to capture vapor, while the left condenser undergoes the same melting process via the de-icing tank.
3.Continuous Alternation of 100㎡ Vacuum lyophilizer:
The system switches between condensers without interrupting the freeze-drying process.
Ice is melted in parallel with sublimation, avoiding downtime.
4.Advantages:
No Additional De-icing Time:
Traditional freeze-drying requires stopping to melt ice, reducing production capacity.
This system of Commercial lyophilizer eliminates idle time, maximizing throughput.
5.Energy Efficiency:
Uses negative pressure vapor from the chamber to melt ice, reducing external energy input.
Automated & Continuous Operation:
The sealing door mechanism automates switching, ensuring seamless transitions between condensers.

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.
