In the selection and design stage, we should take into account restrictions on the dryer noise, as for air suspension dryer, fans are the main generation source of noise. Another pump, gear box, compressor, spray device, a burner, a stirrer can also generate noise. To reduce fan noise, means to decrease the pressure drop required to obtain a higher wind effect, it needs a higher pressure drop, which is contradictory.
Heated by the air stream, especially simple direct-fired gas heated dryer can achieve the effect of low noise. On the other hand, multi-effect air return type device has a burner and requires auxiliary equipment. The noise is higher.zrf
