FAQ
What materials can be processed by the Large Freeze Dryer?
The Large Freeze Dryer is widely used for freeze drying fruits, vegetables, coffee, tea, herbs, seafood, and other heat-sensitive materials. It is designed to remove moisture through vacuum sublimation while maintaining the original shape, color, flavor, and nutritional characteristics of products.
How does a Large Freeze Dryer work?
The Large Freeze Dryer uses a low-temperature freezing process combined with vacuum drying technology. Under vacuum conditions, the frozen water inside the material directly changes from solid ice into vapor through sublimation, allowing efficient drying without high-temperature treatment.
What is the capacity of the Large Freeze Dryer?
The processing capacity depends on the chamber size, shelf area, and material characteristics. Chendun provides different configurations and customized designs to meet various production requirements, from pilot-scale processing to industrial batch production.
How long does the freeze drying process take?
The drying time depends on factors such as material type, moisture content, loading quantity, and required final moisture level. Generally, the complete freeze drying cycle may take several hours to more than one day. Process parameters can be optimized according to different products.
What are the advantages of using a Large Freeze Dryer for food processing?
Compared with traditional drying methods, freeze drying can better preserve the original color, aroma, texture, and nutritional components of food products. It also provides excellent rehydration performance and extends product shelf life without the need for high-temperature drying.
Can the Large Freeze Dryer be customized according to specific requirements?
Yes. Chendun can provide customized solutions based on production capacity, chamber size, shelf quantity, material characteristics, and application requirements. Optional configurations are available to optimize the equipment for different freeze drying processes.
