Product Description
The pilot-scale vacuum freeze dryer simplifies the drying process, avoids material pollution, and realizes the automation of drying and sublimation.
The ZLGJ-20 freeze dryer has shelf heating and programmable functions, and is equipped with a USB socket for easy observation of the freeze drying process.
Product Features
- The door of the drying chamber and the door of the cold trap are made of aviation acrylic material, with high strength and no leakage.
- Seven-inch true color industrial touch screen, high control precision, stable performance and simple operation.
- Well-known brand compressor, high efficiency and energy saving, more stable operation.
- High vacuum safety diaphragm pump is used for the inflation valve and water discharge valve; inert gas can be connected to prolong the shelf life of the material.
- With manual and automatic two modes.
- The visual window is convenient to detect the temperature of the partition, the temperature of the cold trap, the degree of vacuum, etc.
- With data recording, exporting and other modes.
- Temperature control method: standard temperature rise and fall, smooth temperature control.
- Freeze-drying curves such as vacuum degree and temperature can be viewed at any time.
- User level authority password can be set to enter operation management by authority.
- The machine can store 40 sets of freeze-drying processes, and each set of processes can be set to 36 stages.
- The machine has fast defrosting speed and high safety performance.
