PFD Series Pilot Freeze Dryer Pilot Scale Lyophilizer Medium Capacity Freeze Drying Machine for Food Herbs Pharmaceuticals Biotechnology
The Pilot Scale Vacuum Freeze Dryer has changed the tedious operation of the traditional drying process, prevented the pollution of materials, and realized the automation of drying sublimation. The dryer has the function of shelf heating and programming, can remember the freeze-drying curve, Comes with USB flash drive output function, convenient for users to observe the freeze-drying process of mate.
Freeze dryer, also called a lyophilizer, gently removes moisture through low-temperature freezing and vacuum sublimation. It preserves color, nutrients, aroma, and activity, making it ideal for food, pharmaceuticals, biotechnology, herbs, and pet food. We offer household to industrial models for both small-batch research and large-scale production.
①The sealing door of the drying chamber is made of aviation grade acrylic material, high strength without leakage.
② Seven inch real color industrial touch screen, high control precision,stable performance, easy to operate without instruction manual.
③ International famous brand compressor, high efficiency,energy saving, more stable.
④ Manual, automatic mode selection, manual mode is used to explore the process; Automatic mode for mature process, one click operation.
⑤ Monitoring screen; Real-time monitoring of shelf temperature, cold trap temperature, vacuum degree and other operating states.
⑥ Freeze-drying curve query function, you can view the temperature,vacuum and other curves at any time.
⑦Set the user level permission password to access the operation management by permission.
