Pilot freeze dryers system

• In-situ freeze-drying: electric-heating FD-30F-RE dries in the same chamber to avoid material contamination and realize automated sublimation
• Programmable heating; stores freeze-drying curves for observation and repeatable processes

Refrigeration system

• Dual-stage cooling technology for easier maintenance
• Famous-brand hermetic compressors (e.g., Tecumseh, DANFOSS) for low noise and strong cooling performance
• Danfoss pressure controller and valve for high stability
• Condenser: up to -86°C for silicone oil machines, -60°C for electric heating machines; fast cooling from +20°C to -40°C within ~30 min
• Shelf temperature range -50°C to +70°C ±1°C (balanced)
• Air-cooled operation possible in-room without extra cooling device
• Uses CFC-free refrigerant and brazed plate heat exchanger

Dry chamber

• Rectangular dry chamber; pre-freezing and drying occur in the same chamber without manual transfer
• Chamber and shelves: polished SS304 (SS316 optional for contact parts); high-transmittance plexiglass door for observation; rounded inside corners for easy cleaning
• Inner wall roughness ≤ 0.6 μm; shelf flatness ≤ ±0.5 mm/m to ensure uniform drying
• Shelf heating: oil-circulation heating (high-precision) typical for medical/bio; electric heating suitable for food applications
• Shelves use safe voltage; heating rate controllable; mirror-polish stainless steel shelves tested for roughness and flatness to provide temperature uniformity
• Wall-cross heating is optional to meet GMP standard

Condenser (cold trap)

• Large-capacity condenser made of SS304 (SS316 optional for corrosive materials)
• Lowest condenser temperature: up to -86°C (silicone oil machine), -60°C (electric heating machine)
• Fast cooling from +20°C to -40°C within ~30 min
• Independent cylinder-type cold trap available on certain models (powerful ice removal). Cooling-pipe condenser used on FD-30F-RE and some models
• Patented gas diversion for even cold trapping and high ice-catching ability
• Electric heating around condenser chamber for effective ice removal

Circulation system

• Grundfos (Denmark) shielded circulating pump and PID-controlled electric heating components
• Circulation fluid: low-temperature, low-viscosity silicone oil
• Circulation system applied on FD-20F, FD-30F-TP, FD-50F, FD-100F, FD-200F series

FD-LYO control system

• Flexible manual + automatic control modes: manual, semi-auto and auto for batch and pilot production
• PLC control with graphic touchscreen (standard 7" LCD; Siemens PLC and 10" touch optional)
• Shelf temperature adjustable and controllable; storage of process curves
• 32 programs; each program up to 36 segments; curves storable and parameters modifiable in real time
• Built-in recorder; USB export for data analysis; optional FD-LYO PC software and remote control
• Sensor calibration function to ensure long-term measurement accuracy
• Real-time alarm display and historical alarm inquiry for diagnosis and maintenance
• User levels and password protection for decentralized operation
• Optional WIFI remote control via PC or mobile app

Vacuum system

• Two-stage rotary vane vacuum pump standard; vacuum adjustable automatically
• Ultimate vacuum can reach ~1 Pa; higher-performance vacuum pumps (LEYBOLD / ULVAC / Edwards) optional
• Pump performance: atmosphere to 10 Pa in <30 min (typical)
• System leak rate < 10 Pa·L/s

Safety protection

• Comprehensive machine protection with logic interlocks
• Protection for electrical, vacuum and heating systems; real-time alarms for system faults
• Power-off/on and sublimation-process protections
• Material protection during sublimation; heating cut if vacuum is insufficient
• Condenser-vacuum interlock protection

Other features

• Normal bulk type suitable for raw products such as food, fruit, herbal medicine and bio materials
• Stoppering type available for vials (stoppering caps into vials)
• Inflatable (water) valve with safety diaphragm; can connect to inert gas source to dry and fill with inert gas to extend shelf life
• CE / ISO 9001 / ISO 13485 / ISO 14001 certificates; can conform to GMP as required

Main components (summary)
