Description
● Because the hot air passes through the layer of raw material several
times and acts counter motion towards the raw material, the heat
exchanger is fully preferment and thermal efficiency is high.
● The structure is compact and it occupies samll area.
● The stay time of raw material in the helix bed can be adjusted and
the operation is very convenient.
● The raw material acts the motion if circle at helix bed from up to low,
at the same the equipment can jump itself, so the contact surface
between hot air and raw material is increased too and the dry effects is strengthened.
● The equipment is suitable for continuous operation because of continuous feeding and discharging raw material
meanwhile it is easy to meet the requirements of “GMP”.
● It does not damage the surface and shape of raw material basically. It can not only maintain the roundness of pill
but also decrease the rate of pills
