    Yes it is to get rid of the ice on the throttle blades. It seems to build faster on a screw blower than a Roots but happens on both. If it builds at idle then the idle rpm will drop and it could stall. Also the blades could stick. It is caused by the small gap set in the blades acting like an orifice or expansion valve in an airconditioning system.
