First, the operation of a small freezer dryer

1, even the total power cord, open the right side of the yellow power switch. At this time, the cold trap temperature display window begins to show the temperature of the cold trap;

2, click on the "refrigerator" switch, the refrigerator began to operate, cold trap temperature gradually reduced. In order to make the cold trap and the ability to fully absorb water, the pre cooling time should be no less than 30 minutes;

3, click on the "vacuum meter" switch, vacuum at this time as "999";

4, after the end of the pre cooling, will be ready to be placed in a dry dry dish, and then the organic glass cylinder cover;

5, press the fast inflating valve (located in the front right panel) on the stainless steel sheet according to, hear clicks, fast charging valve connection mouth out with automatic sealing;

6, press the "vacuum pump" switch, vacuum pump began to work, vacuum display "999", until 1000Pa below, can show the actual vacuum, freeze-drying process began;

Note: when the vacuum pump starts to work, press the organic glass cover for a moment.

7, multi manifold type: first of all, the rubber valve should be closed (the spool length up), when the vacuum degree of 20Pa or less, will be frozen at the end of the freeze dry bottle into the rubber valve interface, the plastic spool down 180 degrees. Note: this time the vacuum will show a rebound, should be in the vacuum degree of 20Pa or less, then install a bottle;

8, T type frame: first of all, the rubber valve should be closed (the valve core rubber pipe), when the vacuum degree of 20Pa or less will be frozen at the end of the freeze dry bottle into the rubber valve interface, the plastic spool rotation 90 degrees. Note: this time the vacuum will show a rebound, should be in the vacuum degree of 20Pa or less, then install a bottle.

Two, small freeze dryer shutdown operation

1, the fast inflating valve nozzle insert, fast inflatable seat, and closed the "vacuum pump power switch, the air slowly into the cold trap; if filled with inert gases, the inert gas decompression tube connection" charging port";

2, off "vacuum gauge", "refrigerator", such as long-term should not unplug the power cord;

3, lift the plexiglass cover, will take out the goods, preservation, freeze drying process;

4, the cold trap in the ice into water, the water needs to be discharged from the rapid inflation valve outlet, similar to the operation and inflation;

5, clean the cold trap moisture and impurities, proper maintenance equipment. When the vacuum pump is not used, the exhaust nozzle should be covered to prevent dirt from entering;

6, multi manifold type, should be one by one to close the rubber valve and remove the freeze-dried bottle and then repeat the shutdown operation.
