Freeze dryer combined with microcomputer control

In order to further improve the performance of the freeze dryer, based on the existing various types of freeze dryers, our company absorbs the latest foreign technology and combines the software and hardware technologies such as microcomputer control, frequency selection, temperature measurement and protection. The dryer has the advantages of advanced technology, reliable performance, simple operation, beautiful appearance, clear and bright display, accurate temperature measurement and temperature control.

Shutdown operation:

1. First slowly (must be slow, otherwise the oil in the vacuum pump will suck up) Open the "inflation valve" and press the "vacuum pump" power switch to make the air slowly enter the cold trap. To fill the inert gas, connect the decompression conduit of the inert gas to the “inflation port” and slowly open the “inflation valve” to allow the inert gas to slowly enter the trap.

2. Press the “vacuum meter” and “refrigerator” switch in turn to turn off. At this time, the indicator light is off, “total power” is turned on, and the button is released after pressing for three seconds without turning on.

3. Lift the plexiglass cover, remove the item, store it, and freeze the drying process.

4. After the ice in the cold trap has turned into water, open the “drain valve” to drain the water.

5. Clean up the moisture and impurities in the cold trap and properly maintain the equipment.

6. When the vacuum pump is not in use, it should be covered with a spout to prevent dirt from entering.

7. Multi-manifold type, the rubber valve should be closed one by one and the freeze-drying bottle should be removed before repeating the shutdown operation.

Precautions: Do not switch frequently during operation. If the chiller stops running due to operational errors, it cannot be started immediately. Wait at least 20 minutes before starting again to avoid damage to the chiller. After each freeze-drying, the ice on the cold trap coil is turned into water, and then the towel is cleaned and lyophilized. When the "inflation valve" is unscrewed to the cold trap, it must be slow to avoid damaging the vacuum gauge.

Instrument maintenance 1. Keep the surface of the compressor fins clean and clean with dry cloth and dry brush. 2. The rubber ring should not be oiled under normal circumstances, but it should be kept free of particulate impurities. 3, keep the ambient temperature moderate, too high or too low will lead to oil leakage. 4. During the use of the vacuum pump oil, the eye side changes from light color to yellow, brown, brown or even black. To replace the new oil in brown, the oil scale should be ≤ 1/2, and the suspension should be changed when the oil window is found. oil. If the oil separator separator above the pump exceeds 1/2, it needs to be drained.
