Process freeze dryer FD-PE series

pilotfor the food industryfor the pharmaceutical industry

Product overview
FD-PE series universal vacuum freeze dryer is designed for lyophilization of pharmaceutical raw materials, herbal medicines, biologicals, food, fruits and chemical intermediates. Models cover pilot to large-scale production with shelf areas from 1.15 m2 to 60 m2.

Advantages

• Separator with patented design for high pressure resistance, flatness and uniform shelf temperature.
• High-efficiency mixed refrigerant for lower freezing point and improved heat exchange.
• Drying-curve optimization algorithm controlling heating rate and vacuum during drying.
• Patented gas diversion and control for strong vapor capture and improved drying efficiency.
• Vacuum adjustment during drying to prevent foaming or blow-up of sensitive materials.
• Industrial embedded touch HMI and SH-HPSC-IV modular controller for accurate process control.
• LYO-CONTROL system for recipe storage and real-time process adjustments; optional LYO-MEGA host for long-term data logging and traceability.
• Manual and automatic modes to support process development and batch production; user-level access and password protection.
• Customizable configurations and choice of compressor brands where specified.

Main functions

• Refrigeration system with Tecumseh or Bitzer compressor options.
• Vacuum system with ultimate vacuum ≤ 5 Pa and vacuum regulation during drying.
• Circulation and automatic water drain systems; auto defrost and automatic backfill control.
• Freeze point test, automatic pressure rise test and sensor calibration functions.
• Automatic and manual operation with data recording (example: 60 days onboard for certain models).
• 7.5-inch industrial touch screen HMI and dedicated controllers; optional host PC integration.

Specifications

• Model range: FD-P1E/1SE up to FD-P60E/60SE covering shelf areas 1.15 to 60 m2.
