The freeze dryer is a device that uses refrigeration combined with vacuum and then electronically controlled. Refrigeration is the pre-frozen material to carry out the subsequent vacuum sublimation drying process. In addition, the refrigeration cold well is also critical to capture the sublimated moisture, so refrigeration The temperature and cooling capacity are very important. Another link is vacuum. The effect of vacuum determines the ability of sublimation.
Classification of freeze dryers
Freeze dryers are divided into laboratory, small/domestic freeze dryers, pilot-scale laboratory freeze dryers, production freeze dryers, and vacuum freeze dryers. Freeze-drying equipment, mainly used for scientific research, colleges, bio-pharmaceuticals, and household integrated multifunctional freeze-drying machines, freeze-drying biological preparations, polymer materials, peptides, graphene, stem cells, fruits and vegetables, seafood, animals and plants. For the products you want to dry, for heat-sensitive substances such as antibiotics, vaccines, blood products, enzyme hormones and other biological products, freeze-drying technology can show its superiority.
Freeze-dried items are easy to store for a long time, and can be restored to the state before freeze-drying after adding water and maintain the original biochemical properties. This series of models has shelf heating and programmable functions, and can view the freeze-drying curve, which is convenient for users to observe the freeze-drying process of materials.
Features of laboratory freeze dryer:
- Imported fully enclosed refrigeration unit, low temperature and strong water catching capacity. Air cooling is used to dissipate heat without water cooling;
- The vacuum connection adopts international standard parts, which is easy and convenient to disassemble and install, and the sealing performance is reliable;
- The temperature of the cold trap and the vacuum degree of the sample are displayed by LED numbers, which are concise and clear;
- Specially designed Touch the soft keys to quickly and accurately realize the function settings, simple and convenient operation;
- Transparent bell-type drying chamber, natural heating, safe and intuitive;
- Specially designed stainless steel sample rack, ordinary sample trays can be adjusted in space, and the number of layers can be set freely Fixed;
- Stainless steel cold trap and countertop, clean and sanitary, beautiful and corrosion-resistant.
Features of pilot freeze dryer:
- In-situ pre-freeze drying;
- Silicone oil heating, high temperature control accuracy, shelf temperature difference ≤ 1 ℃, uniform drying effect;
- shelf temperature adjustable, controllable production process;
- Can store N Each program can be set up to 24 segments. freeze dryer can modify the program parameters during operation, and record the vacuum drying curve and data online; all operation traces can be recorded;
- Because the drying chamber and the cold trap are separate Structure, strong water catching capacity, short drying time;
- Computer operation, PIC control, can set power-on password, display drying curve;
- The square tray is not easy to be deformed, easy to operate, and easy to clean;
- Equipped with a gas valve, which can be filled with dry inert gas;
- The drying room adopts a high-transmittance, colorless and transparent plexiglass door, which can clearly observe the changing process of the material during operation;
- Remote control operation settings can be selected under the condition of the network;
Features of the production freeze dryer:
The design index of the production freeze dryer can be selected and configured in the options according to the user’s own needs. Since the XY-GY series freeze dryer adopts standard modules, this will reduce manufacturing costs and shorten the manufacturing cycle on the basis of ensuring performance and reliability. Production freeze dryers are used for efficient freeze-drying production processes.
Since freeze-dried products usually have high value, the design of freeze dryers takes into account the safety of the products to the greatest extent. On the basis of equipment versatility, reliability and long service life, XY-GY series freeze dryers also fully guarantee the safety of users and the environment.
The design of the freeze dryer is based on mature technology, using high-quality materials and components that are widely accepted in the pharmaceutical industry. At the same time, a high-tech manufacturing process is adopted, and the equipment fully complies with cGMP standards.
The standard module configuration of the freeze dryer can shorten the time required for equipment installation and commissioning. An XY-GY series freeze dryer includes shelves with cooling or heating, cabinets, cold traps, refrigeration systems, vacuum pumping systems, etc., as well as related instruments, controls and safety interlocks.
Since the products of the pharmaceutical industry usually have high value, high attention is paid to product safety, which is why many parts of the system are backed up. The system adopts a compact design. If necessary, some assembled parts can be separated for easy transportation. Provide an independent control cabinet.
