Main Supporting Systems

Industrial big scale split Freeze Dryer（images 8）

Raw Material ProcessingAn automated, VFD-controlled conveying system that ensures uniform material distribution and physical integrity from pre-processing to freeze-drying trays, maximizing throughput.

Material Freezing SystemThe core pretreatment process achieves deep freezing and physical solidification of materials, locking in the original structure and nutrients of the food before high-vacuum sublimation.

Dry SystemThe core dehydration process perfectly preserves the nutritional components and rehydration properties of food without damaging its physical structure.

Vacuum SystemCreate an extremely low-pressure environment to reduce sublimation resistance and ensure that water is removed directly without thawing.

Heating Medium SystemPrecise control of the heat transfer rate provides thermal support for moisture sublimation, ensuring a stable and controlled drying process.

Refrigerant SystemPrecise cooling pre-freezes materials and provides continuous cooling capacity to the cold trap, achieving efficient water vapor capture.

Pneumatic SystemIt provides a power source to drive the precise movements of various pneumatic components, ensuring the airtightness of the system and the automation of the process.

Ice Melting SystemQuickly remove ice buildup in the cold trap, shorten production intervals, and improve overall machine operating efficiency.

Electrical Control SystemCentralized control of machine parameters, support for formula storage and fully automated operation, ensuring the stability of the production process.
