How you can: freeze prior to drying, initial ready dried goods placed inside a cryogenic refrigerator or liquid nitrogen, so that water freezes strong, freeze drying. Connections between hosts along with the vacuum pump from the vacuum tube, connections with international common clamp. Hoop containing a sealed rubber ring, prior to connecting on a rubber ring which can apply the ideal amount of vacuum grease, then clamp fastening. Host energy outlet around the suitable side with the Panel equipped with vacuum pump, the vacuum pump energy cable connected. Verify the vacuum pump, acknowledge raises vacuum pump oil, not oil-free operation. Oil level shall not be much less than oil lens center line. Master cold trap at the top rated of the „o“ type rubber packing rings should be kept clean, and when used for the first time, is usually coated having a thin layer of vacuum resin, Plexiglas cover placed around the rubber rings gently swiveling, conducive to the seal.
Energy operation:
1. connect to the power provide line, appear in the total energy led is blinking, blinking description the energy provide is connected.
2. press the „main power supply“ on essential for three seconds, at which point a „cold trap temperature“ show window began to display the temperature of cold trap, let go with the important.
three. press the „refrigerator“ on essential, refrigerator running, cold trap temperature drift down. To produce the cold trap sufficient moisture adsorption capacity of cold shall be not much less than 30 minutes.
4. press the „vacuum gauge“ on key, and vacuum digital display for the „110“, „103“ led is on.
five. after the finish of cold, is ready to dry the things placed in dry pan and cast plexiglass cylinder, pneumatic valve and drain valve (located around the correct side of Panel) clockwise to tighten.
6. press the „vacuum pump“ get started design and style for vacuum pump commence working, digital show down till much less than 20Pa, freeze Drying Machine process starts. Note: when the pump starts operating, plexiglass cover beneath a moment conducive to seal.
7. multiply manifold variety rubber valve need to be close (extended spool up) till the vacuum reaches 20Pa will freeze lyophilized bottle insertion the end below the rubber valve interface, plastic cartridge rotate 180 degrees. Note: the vacuum Gage are going to be picked up at this time, when the vacuum reaches much less than 20Pa, then fill a bottle.
Shutdown:
1. very first take (make sure to slow down, otherwise the oil within the vacuum pump will draw) open the „inflate“, simultaneously press the „vacuum pump“ energy on key air gradually into the cold trap. If filled with an inert gas is necessary, then the pressure of an inert gas tubing connection „inflatable“, and then slowly open „inflate“, such that the accumulation of slow into the cold trap.
two. press the „vacuum gauge“, „chiller“ switch off, light is off, the „main energy supply“ on crucial, with no show when on is pressed for 3 seconds soon after release the key.
three. lift the Plexiglas cover, get rid of, save and freeze drying procedure is total.
four. just after the ice turns to water inside a cold trap, open „drain valve“ water.
five. removal of moisture and impurities in the cold trap that right upkeep of equipment.
6. the pump when not in use, should really be covered with mousseur and avoid dirt entering
7. multiply manifold variety, you ought to shut down one by one particular and remove the rubber valve freezing and drying bottles and then repeat the shutdown operation.
Note: in the course of operation usually do not frequent switching, which include the refrigerator stopped running as a result of operating errors, doesn’t get started promptly, wait at least 20 minutes prior to the begin once again, so as to not harm the refrigerator. Right after freeze-drying and cold trap coil ice into water and cleaned having a towel unscrew the end of freeze dried „inflate“ on the subject of cold trap air, make certain to slow down to avoid washing vacuum gauge.
