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. Freeze drying technology is used in particular for removal of moisture from the products usually of biological origin without causing any noticeable change in the original characteristics. Freeze Drying is also the preferred process in the field of Pharmacy, Chemistry and in conservation of food. Heat-sensitive biological materials may be freeze-dried without affecting their potency. The dried materials may be stored for years at room temperature without loss of their original characteristics. The freeze-dried material may be transported and shipped in small containers, and no provision is necessary for refrigeration en route.

Beside the normal drying applications our freeze driers are fit to be used for various applications tests involving micro-organisms, plants, tissues etc apart from various customized industrial and research applications.

Bacterial growth and enzyme action do not take place in freeze-dried products. Proteins do not coagulate. Oxidation of many materials such as hemoglobins and vaccines is completely prevented when drying and sealing is done under high vacuum.

Pilot Scale Freeze Dryerare 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. WEIBERPilot Scale Freeze Drierare 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 ourPilot Freeze Drierare fit to be used for various applications tests involving micro-organisms, plants, tissues etc.

• Defrosting without water: Radiation from shelf defrost ice condenser coils fast and efficient. No production of additional waste.
• Most efficient condenser design: Ice condenser coils directly inside drying chamber improves drying time and prevents vapour bypass to vacuum pumps.
• 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).
• Micro-processor based Controllers (HMI+PLC as an option)
• Hermetically sealed compressor maintains temperature up to -80C
• Temperature controller cum indicator Vacuum drum is made of non-magnetic Stainless steel
• Quick seal valves/ports for manifold drying.
• 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
• Sample containers- Sturdy, borosilicate glass vessels options include flasks, serum bottles, vials, and ampules
• Range of manifolds in clear acrylic or stainless steel for superior corrosion resistance
• One-button auto start-up and shut-down activates all operating parameters in a correct and safe sequence, protecting the product and equipment
• Hot gas defrost and smooth-walled condensers for fast turnaround and minimal delay between runs
• CFC free cooling
• Ethernet communication and USB ports

Tray driers for drying of thermal sensitive materials which get easily resolved, polymerized or deteriorated under higher temperature. It offers no contamination due to closed arrangement inside drier. It is well accepted for economical drying of granules, powder, food material & chemicals.

A highly effective recirculating air system is provided in the Tray Dryers. The heated air, is recirculated with fresh air in selected proportions for optimum drying. The system is designed so that the materials at the top & the bottom dry simultaneously. Uniform air circulation, controlled temperature, sturdy construction and large working space are the valuables of the oven which is suitably designed to cover wide temperature range.

• Microprocessor based ergonomic controller for temperature setting and other parameters.(HMI+PLC based controller as an option).
• Dryer Chamber with Vapor Extraction system & Heating Arrangement
• Simple calibration and auto-tuning function
• LCD/LED display (0.1 resolution) and touch-sensitive keypad
• Corrosion-resistant interior and exterior.
• Audio visual alarm for malfunctioning, over temperature, power failure etc
• RS 232/485 interface. (optional)
• Universal Digital Data Recorder system(optional)
• USB ports for PC connectivity (optional)
• Built-in timer and touch-button controls allows quick and simple temperature setting.
• Temperature chart recorder/printer for printing graphs(optional)

Vacuum tray driers for drying of thermal sensitive materials which get easily resolved, polymerized or deteriorated under higher temperature. Heat sensitive materials can be driedat low temperatures under vacuum, since the environmental pressure is reduced below the vapour-pressure of the contained water or solvents. Oxidation or Contamination by Air is eliminated. HollowFibers, Medical Devices, Chemical Salts, Fine Chemicals, Dyes, Glandular Products, Pharmaceuticals andFood Extracts (Gluten, Glues, Pepsin), Rubber Explosive, etc. are ideally suited for drying in this manner.

Drying under vacuum is also environmentally friendly because the Evaporated Solvents can easilybe re-condensed. These solvents can then either be recycled or disposed of without any problem.

• Temperature range upto 3500C
• Microprocessor based controller (HMI+PLC as an option)
• Dial type pressure gauge (digital pressure gauge as an option)
• Pressure release valve in Steam line.
• Doors hinged with silicon gaskets
• Equipped with vacuum break valve and drain valve
• RS 232/485 interface. (optional)
• Universal Digital Data Recorder system(optional)
• USB ports for PC connectivity (optional)
• Built-in timer and touch-button controls allows quick and simple temperature setting.
• Temperature chart recorder/printer for printing graphs(optional)
