Large Freeze Dryer Machine

The Large Freeze Dryer Machine is designed for industrial freeze drying of food, pharmaceutical, biological, and temperature-sensitive products, integrating pre-freezing, vacuum drying, heating control, and automated process management with customizable capacity and configuration.

Food Manufacturers & Processors: Suitable for small food manufacturers and processors producing freeze-dried fruits, vegetables, juice, tea, coffee, and specialty foods in limited production volumes.
R&D and Product Development Teams: Suitable for food companies and R&D teams conducting product trials, recipe development, process testing, and pre-production evaluation before scaling up.
Pet Food & Specialty Product Suppliers: Applicable to small-batch production of freeze-dried pet treats, meat products, herbs, and other specialty formulations where flexible batch processing is required.
Distributors & Equipment Resellers: Suitable for machinery distributors and process-equipment suppliers serving small food businesses, laboratories, and specialty producers in their local markets.

Pre-Freezing: The product is first frozen to convert its water into ice before vacuum drying begins.
Primary Drying: Vacuum conditions allow ice to sublimate directly into vapor, removing most of the frozen moisture.
Secondary Drying: Controlled heating removes remaining bound moisture after primary drying to reach the required final moisture level.
Cycle Control: Drying parameters can be adjusted according to product type, loading thickness, moisture content, and required end condition.

Five-Tray Layout: The HFD-5S is fitted with 5 trays arranged inside the drying chamber for batch processing.
Tray Size: Each tray measures 190 × 460 × 20 mm, providing a defined product loading surface.
Layer Spacing: The trays are arranged with 40 mm spacing, providing clearance between product layers during drying.
Viewing Door: A thickened transparent door allows operators to observe the chamber without opening the drying system.

Cold Trap: The cold trap coil reaches ≤ -40°C under no-load conditions to condense water vapor released during sublimation.
Vacuum Pump: The vacuum pump has a stated pumping speed of 3 L/s and an ultimate vacuum below 2 Pa.
Automatic Defrost: The automatic defrost function removes accumulated ice from the cold trap after the drying cycle.
Vacuum Protection: The vacuum system maintains the low-pressure environment required for sublimation and separates moisture capture from the pumping stage.
 

Power Requirement: Rated machine power is 1300 W. Destination-country voltage and frequency should be confirmed before purchase.
Installation Space: The machine measures approximately 630 × 550 × 910 mm and weighs 85 kg. Allow additional space for loading, operation, and maintenance.
Ventilation: The installation area should provide adequate ventilation around the equipment and maintain suitable ambient conditions.
User Interface: The touch-screen control interface supports multiple languages, including English, Spanish, German, Japanese, and Korean.

Manufacturing & Customization: Lanphan manufactures freeze-drying and process equipment from laboratory to industrial scale, with OEM/ODM and PLC/HMI customization available.
Project & Technical Support: Services include process consultation, system integration, installation guidance, and after-sales technical support.
Global Supply & Compliance: Lanphan supplies international markets with warehouses in the US, Australia, and Thailand. CE, ISO certifications, and invention patents are available for applicable equipment.
