Features: 1. Freeze-drying automatic control system: Programmable programming, program control from freeze-drying to defrost. 2. Slab heating control system: thermal cycle protection, special heating materials, fuzzy PID control algorithm. The freeze-drying curve optimization control algorithm can control the sample heating rate and the current stage vacuum value in the sublimation and analytical drying stages. 3. Cold trap defrosting system: non-electric heating defrosting mode, high safety performance; defrosting speed is fast, which solves the inconvenience caused by traditional immersion defrosting. 4. Freeze-drying end point test system: The freeze-drying end point test can be automatically performed after the end of the analytical drying stage to ensure that the moisture content of the material reaches the standard requirement. 5. Vacuum regulation system: sublimation and analytical drying process to adjust the vacuum degree to avoid the problem of special material foaming, blowing and speeding up the freeze-drying efficiency. 6. Pulse backfilling system: It can choose three backfilling modes: slow speed, medium speed and fast, which avoids the problem that the effective material is blown away after the lyophilization ends. 7. Automatic drainage system: Interlock with the vacuum system after the end of drainage to avoid the failure of the vacuum system caused by forgetting to close the drain valve. 8. Adopt industrial touch screen, human-computer interaction type is good, easy to understand, easy to operate without manual. 9. Hand automatic mode selection: Manual mode is used to explore process parameters (human intervention is strong), automatic mode is used in the process maturity stage, one-button operation, simple and convenient. 10. Data Recording System: Multiple choices for data logging systems. 1. The local memory storage can store up to 3 months. 2. External storage (U disk), the amount of stored data is related to the capacity of the U disk (optional). 3. PC database storage, the amount of stored data is related to the usable capacity of the computer hard disk (optional). 11. Freeze-drying process recipe storage function: It can store 500 sets of fixed or user-defined freeze-drying process recipes. 12. PC remote monitoring system: It can remotely monitor the running status of the equipment, and the farthest monitoring distance is 1.5KM (optional). 13. Calibration function: Temperature and vacuum calibration can be performed to ensure the accuracy of long-term use of measured values. Freeze-drying curve query function (can query temperature and vacuum curve for process optimization and freeze-drying effect verification).
