Selection processing capacity =Actual processing capacity ÷ (coefficient C1 x coefficient C2 x coefficient C3)
For example: How to choose an air-cooled freeze dryer with an air compressor of 28m3/min, exhaust pressure of 0.5MPa, exhaust temperature of 50 ℃, and ambient temperature of 40 ℃?
Answer: When selecting a processing capacity of 28 ÷ (0.64 × 0.75 × 0.98) =59.5m3/min, the SDLF-60 air-cooled freeze dryer should be selected.
