Operating a freeze-drying machine involves several key steps:
1. Begin by slowly opening the "inflation valve" to allow air into the cold trap. Make sure to do this gradually to avoid oil from the vacuum pump being sucked back. Then, turn on the "vacuum pump" power switch to let the air slowly enter the system. If using an inert gas, connect the decompression tube to the "inflation port" and slowly open the "inflation valve" to introduce the gas into the cold trap.
2. Press the "vacuum meter" and "refrigerator" switches one by one to turn them off. At this point, the indicator light should go out, and the "total power" should remain on. Hold the button for three seconds before releasing it to ensure proper shutdown.
3. Lift the plexiglass cover and carefully remove the item from the machine. This marks the completion of the freeze-drying process.
4. Once the ice in the cold trap has melted into water, open the "drain valve" to drain the liquid.
5. Clean the cold trap thoroughly to remove any moisture or impurities. Proper maintenance is essential to keep the equipment running smoothly and efficiently.
6. When the vacuum pump is not in use, make sure to cover the spout to prevent dust or debris from entering.
7. For multi-manifold systems, close each rubber valve individually and remove the freeze-drying bottles before repeating the shutdown procedure.
