A leading freeze drying machines manufacturer in China, from lab pilot to industrial production freeze dryers.

FDL-TP Stopper Freeze Dryer

FDL-TP Stopper Freeze Dryer

FDL-TP stoppering freeze dryers designed consider a lot of factors that meet your freeze drying demand, widely application in pharmaceutical industry, VIKUMER Freeze Dry provide standard factory models as well as customized solutions/configurations for your pharmaceutical production, our experienced engineer team have strong ability design the most economic freeze dry system ensure your success and high quality freeze drying result.

In principle, pharmaceutical freeze dryers are all customized, our solutions are based on 2 key points: meet your special demand and economic price. The range lyophilizer shelf area available from 1m2 to 20m2, flexible configurations design such as main/sub doors for automatic loading/unloading, External horizon/vertical rectangular/cylindrical condenser, butterfly/mushroom isolation valve, CIP, SIP devices, shelves distance control, backup compressors/vacuum pumps/fluid pumps, dry vacuum system etc.

VIKUMER provide throughout technical support for your FDL-TP pharmaceutical freeze dryer in its life cycle, designing, produce, sea shipping to your nearest sea port, install, worker training, after sale services and maintenance, we help your freeze drying project health running, reduce downtime lose.


  • Stopper Freeze Dryers shelves are movable, flexible move up and down, all shelves distance could be adjust, that means the range of machine include all functions of tray freeze dryers, could either use as a shelf dryer for bulk loading, also it could use for vials capping under vacuum, especially fit vaccine production.
  • All its material use stainless steel 316L, could use various industrial include pharmaceutical, biological, chemical, API, bacteria, vaccine, food.

Safety Freeze Drying

  • The designing of modular system, all mechanical subsystem like vacuum, refrigeration, fluid recycle, heating etc. design and installed modular, during working they are individual working and controlled by high advanced LYO-MEGA system, not influence each other, and the LYO-MEGA system have interlock function avoid mis operate, temperature or vacuum out of set automatic balance system.
  • The state of art treatment to drying chamber (roughness, flatness, easy clean house, slope for drain) and excellent performance (vacuum control, temperature uniformity) also provide a higher energy efficient and precision control.
  • We also design ensure the system reliability in hardware part, customer could select one more suit (compressor, vacuum pump, fluid pump) for backup, once there have a failure, backup units automatic start ensure the failure no influence entire freeze drying process at all.

Meet GMP

  • Drying chamber, doors, shelves, condenser all made of stainless steel 316L with mirror treatment, surface polish roughness Ra<0.5, drying chamber and condenser corner design hemispheric, could thoroughly clean.
  • As per your needs, clean in place/CIP and Sterilize in place/SIP optional. Drying chamber have slope guide CIP water discharge, water ring vacuum pump installed help dry chamber.

Versatility Control System

  • LYO-MEGA controller system which combine PLC + Touch screen based electric cabinet and computer (software) control provide. The control system could meet 21 CFR part 11.
  • The HMI interface or computer software display information from sensors such as shelves, condensers, vacuum (set and actual data), provide operators full control rights of the recipes setting, freeze drying data storage/export/print by data sheet or curve format, manual or automatic working select, as well as the main components working status real-time display.

Stoppering Freeze Dryer Performance:
