A Leading Refrigeration Equipment Manufacturer in China

Lab Freeze Dryer

Laboratory Freeze Dryer

Versatile Laboratory Freeze Dryer

Laboratory research is the first step of new drugs development, lab data acquisition procedures and accuracy are very vital part, therefore, an advanced freeze drying equipment that meet FDA is needed, which could help pharmaceutical manufacturers success transfer research achievement to clinical trials and commercial production in future from R&D department.

Huayu Brother as a renowned freeze drying machine manufacturer and supplier in China, we designed and manufactured a range of freeze dryer from lab to industrial large scale production freeze dryers. Our lyophilizers are delicate design, compact size, high reliability, excellent performance and economic price, we have installed over 1000 sets lab or pilot freeze drying equipment in global, our machine could beat any brand in its class. Please feel free contact us get an offer or solutions.

Our freeze dryer could fit any rigorous research center, help customer build quality control system under CGMP from the start phase, extend to production process.

We supply benchtop freeze dryers for lab research, as well freestanding type floor freeze dryer for pilot produciton or senior development. The shelf area from 0.1m2 up to 3m2. Condensing capacity up to 30L.

About Lab Freeze Dryer


Multi Applications: By bulk or stoppering loading.

The AISI304 or 316L finished shelves, trays, chamber and condenser, enable freeze dryers could easily handle different products include corrosive items, by using stoppering device, also could freeze drying items in various type vials.

Backside of freeze drying chamber, reserve 1 inlet port for manifold connection, flask holder could set in left or right side; validation port also reserved.

Popular Application:

  • Lab research.
  • Pilot production.
  • Heat sensitive products drying.
  • All kinds of food, fruit, pharmaceutical, chemical, biological products Bulk drying or drying in vials.
  • Flask holder, drying in flasks.

Exclusive Features

Considered Design

The lab LYO freeze dryers are designed self-contained body, compact size with casters for move, deliver to customer ready for operation, after plug in and connect compressed air device, all sides panels could open for maintenance.

Reliable System

All parts installed in lab LYO freeze drying system have been carefully select from world famous brand, right model select, highest quality, entire system assembled go through years’ lasting to verify its reliability and stability. Temperature probes, vacuum pressure gauges, parts that have variable and will influence the drying result have go through strict validation and test, the sensors installed in lab LYO freeze dryer, its accuracy is warranted. Ensure you a precision data and procedure.

Heavy Duty Chamber

Drying chamber, shelves, trays and condenser are made from AISI316 material, superior craftmanship ensure its flatness, roughness is same as production units. Drying chamber have rounded corners easy cleaning, both drying chamber and condenser have transparent door, lock by EXCLUSIVE compression lock method, door rubber seal is special made, >100000 open/close no leakage according to our lab test.

Condenser and drying chamber isolate by butterfly valve, that could test pressure change, judge drying finish or loading material without defrosting, condenser defrosting by hot gas.

Precise and Uniform Temperature Control

Fluid recycle system used for shelves cooling or heating, all shelves are sandwich structure, inside have channels for fluid recycle, heating by individual electric heater, cooling indirect through plate heat exchanger, shelves temperature balance system allow the tolerance <±1C during sublimation.

Fluid temperature probe installed, real time display the fluid set temperature and real temperature, vacuum sensor in the drying chamber monitoring vacuum degree change and assist electric heater working, support/avoid overheating during sublimation.


Advanced Control system

PLC + Touch Screen

One prominent feature of LYO freeze dryers is its high advanced control system, the system adopt PLC and user friendly Touch Screen controller, its same function as industrial units, which include:

  • Log in and authority management.
  • Parts/valves working status.
  • Freeze drying recipes management.
  • Drying curve display.
  • Drying data export by batches.
  • Automatic or semi-automatic working select.
  • Alarm information.
  • Data download.

Optional, PC suit provide more convenient freeze drying operation and data storage.

Excellent System Performance
  • Designed to meet user requirement, LYO freeze dryer delivered with excellent system performance:
  • Shelves cooling from +20C to –40C within 60min.
  • Shelves lowest temperature –55C (accuracy 2C).
  • Shelves heating from –40C to +20C within 60min.
  • Shelves Max temperature +80C (accuracy 1C).
  • Ice condenser cooling from +20C to –40C within 30min.
  • Ice condenser lowest temperature –80C.
  • Ice condenser defrosting time within 60min.
  • Vacuum pump from atmosphere to 0.1mbar within 30min.
  • System final vacuum 0.01mbar, leakage ≤5x10-2mbarL/s.
