Vacuum freeze dryer
1. High quality equipment and matching solutions were provided.Different system functions and components configuration can be customized in order to meet different users' needs.
2. The parts were compacted for the modular design, so the equipment was easy to maintain and operate.
3. The interface of the control system was friendly, the operation was convenient and the function was powerful.
4. It was highly close to the principles of production machines.
5. Configuration parts of well-known brands at home and abroad were used.
6. AII interfaces shall be flange mounted.
7. All kinds of sensors were equipped.Timely alarm and active protection will be took when the function of the equipment were abnormal.
8. In order to easily operate in the clean room, external drying box can be connected for the small experimental freeze -drier.
9. Pilot freeze-drier was designed in accordance with the national pharmaceutical machinery industry standard.
The control system was composed of programmable logic controller, man-ma-chine interface device, sensor, terminal relay and digital to analog conversion module. The industrial intelligent control software was based on professional programmable controller and developed by advanced configuration configuration software for vacuum freeze-drying equipment.It was that can display the system status, process flow, alarm point and operation situation of each component, and can be monitored remotely.
1. It can automatically control the whole freeze-drying process with one key,and also can realize the freeze-drying process manually；
2. The system can show a variety of language interfaces such as Chinese and English [Russian, India (export optional)]. The system vacuum can be freely converted at mbar, Pa and Torr. The temperature can be expressed in degrees Celsius and Fahrenheit ;
3. During the operation, the system can automatically monitor and detect and record and store the relevant data. It can also be monitored by remote systems ;
4. From freeze-drying process to defrosting process, all materials can be programmed automatically and many programs can be stored ;
5. The system was equipped with variety sensors, it can alarm immediately during the operation of abnormal temperature or pressure, and take active protection to ensure safe and stable operation ;
6. Data was recorded once a minute with freeze-drying curve. The system can record real-time data continuously and has USB data storage serial port ;
7. The freeze-drying process was recorded, the freeze-drying curve was drawn and the eutectic point test was achieved ;
8. The man-machine interface equipment of the control system can work stably in the environment from -20 to 65 degrees Celsius. It conforms to the NEMA (International Electric Manufacturing Association) protection regulations and the European CE Electrical Certification standards ;
9. Automatic vacuum regulation was achieved in this system.
The freeze-drying cycle system consists of intermediate medium, circulating pump, heater,plate heat exchanger, freeze-drying chamber, shelf and pipeline. The freezing and heating of materials are completed with this system.
1. The freeze-drying process was managed. A number of mature and safe freeze-drying process were stored in the management system. Users can make up for different products of freeze-drying process when they adjusted freeze -drying process data；
2. Material can be observed and the freeze-drying parameters can be adjusted at any time in the freeze-drying process；
3. The freeze-drying chamber can effectively pre-freeze the material；
4. PID algorithm is used in the automatic control. Materialscan be repeated freeze quickly or slowly；
5. The temperature was even by accurately controlling the medium circulating in the shelf heating system and the shelf was smooth with the special process. The quality of freeze drying and the drying efficiency were improved；
6. The gland system can perform manual or automatic accurate and reliable sealing of the material container in the freeze-drying chamber in a vacuum state, the container lid and the container can be reliably sealed;
7. The ice condenser can be defrosted rapidly through the defrost system after freeze-drying process so as to freeze the material again.
The system is composed of vacuum pump or roots pump (optional), freeze- drying box, vacuum gauge, pipeline and controller. The vacuum pump was equipped with redundancy.
1. The vacuum degree was controlled by PID mode, and the whole automatic control can be realized；
2. Systematically standardized test procedures were took in order to avoid potential vacuum leaks；
3. A device at the suction port of the vacuum pump was provided to prevent the gas flowing back when the equipment was stopped. An oil mist filtering device at the exhaust port is provided to prevent the exhaust gas polluting the surrounding environment；
4. The vacuum can be adjusted automatically or manually. The efficiency of the heat transfer and freeze drying was increased and the equipment and energy consumption was reduced；
5. The butterfly valve of the pilot freeze-drier between the freeze-drying chamber and the ice condenser should be closed before freeze-drying preparation and the terminative process. So the material can be handled and pre-frozen in a clean environment.
The utility model was composed of a refrigeration compressor, a condenser and an expander, etc. An imported compressor was adopted in the system. The shelf and the water catcher were respectively cooled by the slicon oill and the condensing pipe. The system was simple and reliable. The cold capacity was enough also.The environment-friendly refrigerant was used in the system. The system can be delay started and automatic controlled.
