  • Pneumatic system uses for vacuum and water system.
  • Freeze drying process fully automatic with abnormal protection procedure.

Power saving technology.

  • Perfect electric consumption control technology benefits you 1kg wet material to dried as low as 2kwh.
  • Multi methods power saving combination from hardware to software, e.g. control system all time collect and analysis data, after precision calculate, automatic power off 1 or more compressors without influence the system stability to achieve power saving, same for other parts.
  • Exclusive designed shelf/plates structure, a higher energy use ratio that strong guarantee both the shelves and drying chamber temperature uniformity, High quality freeze dried with shortest time.

High reliability.

  • Only world 1st class brand components will be installed in our system, like Bitzer compressor, Leybold vacuum pumps, AISI304 heat exchanger, WILO centrifuge pump etc.
  • The renowned brand parts will benefit you not only the low maintenance fee, rarely downtime, also the high performance ensure your freeze-drying process smooth going.

Extraordinary performance.

  • With very precision shelves and drying house temperature uniformity control, the raw material in all plates its temperature uniformity and sublimation speed is very close.
  • Shelves temperature raise or reduce is sloped. softly reduce or raise minimum harm to raw material.
  • The just right compressors for condenser design temperature -45C, during sublimation period could stable between -40C to -45C, ensure the condenser vapor collect capacity and speed.

High quality freeze dried.

  • We guarantee you: All batches freeze dried products quality is constant!
  • Compare and have verified by our customers, drying by our freeze dryer, dried speed, dried quality, power consumption, automation level, failure rate, batches quality consistent, all is better, and we have confidence compare and beat any competitor brand.
