Pilot Scale Freeze Dryer

PILOT SCALE FREEZE DRYER

Pilot Scale Freeze Dryer are specially designed for drying processes of large-scale production units(20-100 litres). Prefreezing and drying will be realized on liquid temperature controlled shelves inside the separate drying chamber (double-chamber-system). Due to the temperature control of the stainless steel shelves (via a synthetic heat-transfer medium), these pilot systems fulfil the highest standards of the pharmaceutical and biotech industries.

Freeze drying is the process of removing the moisture from a biological product while maintaining the Integrity of the products biological & chemical structure and activities. WEIBER Pilot Scale Freeze Drier are conceptualized and designed to provide moisture removing solutions to all the microbiology, biochemistry, biotechnology and genetic engineering laboratories which require complete moisture removal and storage facilities of various biological agents/material. Beside the normal drying applications our Pilot Freeze Drier are fit to be used for various applications tests involving micro-organisms, plants, tissues etc.

  • TECHNICAL MATRIX:
  • APPLICATIONS:
  1. Defrosting without water: Radiation from shelf defrost ice condenser coils fast and efficient. No production of additional waste.
  2. Most efficient condenser design : Ice condenser coils directly inside drying chamber improves drying time and prevents vapour bypass to vacuum pumps.
  3. Vial stoppering plus flask drying: Multi-purpose device with optional connections for up to 4 flasks. Controlled and safe vial stoppering via manual operation (automatic as option).
  4. Micro-processor based Controllers (HMI+PLC as an option)
  5. Hermetically sealed compressor maintains temperature up to -80°C
  6. Temperature controller cum indicator Vacuum drum is made of non-magnetic Stainless steel
  7. Quick seal valves/ports for manifold drying.
  8. Vacuum Pump - Providing an environment that allows for easy removal of water molecules from the sample is critical to successful freeze drying. A vacuum pump is needed to lower the pressure around the product being freezed. Select from standard or chemical resistant models to enable freeze drying with more aggressive solvents
  9. Sample containers - Sturdy, borosilicate glass vessels options include flasks, serum bottles, vials, and ampules
  10. Range of manifolds in clear acrylic or stainless steel for superior corrosion resistance
  11. One-button auto start-up and shut-down activates all operating parameters in a correct and safe sequence, protecting the product and equipment
  12. Hot gas defrost and smooth-walled condensers for fast turnaround and minimal delay between runs
  13. CFC free cooling
  14. Ethernet communication and USB ports

Flasks, ampules or vials are individually attached to the ports of a manifold or drying chamber. The product is either frozen in a freezer, by direct submersion in a low temperature bath, or by shell freezing, depending on the nature of the product and the volume to be freeze dried. The prefrozen product is quickly attached to the drying chamber or manifold to prevent warming. The vacuum must be created in the product container quickly, and the operator relies on evaporative cooling to maintain the low temperature of the product.

Weiber Pilot-scale freeze dryers are double walled cooled units. Outer body is constructed out of thick PCRC sheet duly pre-treated with primers and rust proofing and painted with long lasting stove enamel or elegantly powder coated. The inner chamber is made of heavy gauge stainless steel sheet of SS-304 grade. The gap between the walls is filled high grade mineral glass wool, which ensures maximum thermal efficiency.

The unit is provided with a nonmagneticstainless steel bottom for an easy removal of effluents. The vacuum drum of our unit is made of stainless steel sheet of ss-304 grade with top cap made of heavy Perspex sheet of 8/12” valve for manifold drying .

Double stage Vacuum pumps with gas ballast giving vacuum 1 X 10-3 torr module gauge sample port having 12.5mm outer dia provided for Quick drying however, moisture contains would be around 5% in the specimen.

Electronic Vacuum indicator Pirani gauge is used. Specially designed temperature indicator to read temperature as low as 80°C, mounted on front panel. Suitable work on 220V single phase. 50HZ A.C.

An energy efficient cooling unit is installed in our laboratory lyophlizer. We use ISI marked high end CFC free compressors of Kirloskar/Tecumseh make, conforming to latest international standards and guidelines.
