Saldēšanas žāvētāja plāksnes slāņa temperatūras vienveidības tests

(1) Pirms pārkalibrēšanas . Pirms verifikācijas ievietojiet verifikācijas temperatūras zondi un standarta temperatūras zondi vienlaikus labi sausā temperatūrā un veiciet pirmskalibrēšanu ., kalibrēšanas nolasīšanas novirzei jābūt <0 . 5 grādiem.

(2) Connect the calibrated temperature probe into the freeze dryer through the verification port, place the 1-23# temperature probe, the numbers 1-5 represent the freeze-dryer product layer, and T1-3# is the temperature probe placed on the first The silicone oil inlet, outlet and center position of 3 layers, and other temperature probes are placed at the 4 corners and center positions of each layer. Start the freeze dryer, set the temperature of the heat transfer oil to 3 points of 4{{10}}℃, 0℃and 40℃, respectively. After the inlet and outlet temperatures of the heat transfer oil reach equilibrium at each set temperature point, run for 30 min, and keep at -40 The uniformity of the layer temperature at℃, 0℃and 40℃. Perform 3 replicate tests. After the verification test is completed, the temperature probe will be used for post-calibration. The calibration points are set to 3 points of -40℃, 0℃and 40℃, and the reading deviation of the pēc kalibrēšanas jābūt<0.5°C.

(3) Eligibility criteria. According to the national pharmaceutical machinery industry standard JB T20032--2012 "Medical Vacuum Freeze Dryer", and combined with the product process requirements, when kept at 40℃, 0℃and 40℃, all test points of each board layer have the highest temperature at the same time. The temperature difference between the value and Minimālajai vērtībai jābūt mazākai vai vienādai ar 2 grādiem, un paneļa slāņa vienveidība ir kvalificēta . vienveidība
