Pharmaceutical Bulk Tray Dryers

The Vikumer FDL freeze dryers are tray style lyophilizers, general purpose and capable of freeze drying all types of bulk materials. Such as solid, liquid, paste, granular and powder materials, apply to biological, pharmaceutical and chemical industries.


Vikumer FDL pharmaceutical bulk tray dryers are suitable for a wide range of applications, fit all kinds of bulk materials freeze drying. Such as solid, liquid, paste and powder. They are modularly engineered and integrate structure, designed meet the guidelines of GMP and FDA.

By use of a FDL freeze dryer, your freeze drying task will be fully automatic. Raw products are placed on shelves in drying chamber, in-place freezing and later drying under vacuum environment. During the drying process, raw products always keep in minus temperature, no ruin their biological activities and other chemical properties.

The high advanced PLC and user-friendly HMI based control system enable operator manage freeze dry system easily, precise control of the entire freeze drying cycle. Provide a real time display of system running status, vital freeze drying parameters and data generate. In addition, customer can select PC control suit, to get more powerful functions.

A shelf vacuum freeze drying equipment is multi-purpose, versatile apply to pharmaceutical, biological, plant extracts, chemicals, probiotics and heat sensitive products. Constant high freeze dried quality between trays and batches.
