General Purpose Freeze Dryers

Freeze Drying Bulk Materials

The Vikumer FDL series general purpose freeze dryer is a line of commercial freeze drying machines offer one of the broadest ranges of industry applications, available for bulk materials lyophilization which include probiotics, bacteria, yogurt, enzymes, reagents, chemicals, nutrients and cosmetics. Production capacities ranging from 50Kgs to 600Kgs input per batch.

The high-performance freeze dryers feature rectangular drying chamber which means highest space using rate and exceptional temperature uniformity. The proven advantages result they are particularly fit freeze dry heat sensitive items in pharmaceutical, biological, nutritional and chemical industries.

By using an FDL freeze dryer, your freeze drying task will be fully automatic. Raw products are placed on shelves in the drying chamber, in-place freezing and later drying under vacuum environment. During the drying process, raw products are always kept at minus temperature, biological activities and other chemical properties are well preserved.

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 real time display of system running status, vital freeze drying parameters and data generate. In addition, customer can select the 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.


  • Offering both stainless steel and aluminum alloy shelves, conductive heating or radiative heating, for any application.
  • Available for freeze dry product in trays with varies form: liquid, paste, solid, granular and bulk type.
