| 1. A refiner steam separation system, comprising:
a blowline for transporting a mixture of fiber material and steam;
at least one steam separator having an inlet communicating with said blowline for receiving the mixture therefrom, a waste
steam outlet for releasing waste steam, and an exit for discharging cleaned fiber material from said separator and for preventing
a substantial portion of the waste steam from passing therethrough;
a dryer duct operably associated with a dryer for drying the cleaned fiber material;
at least one relay pipe in communication with said exit and said dryer duct for transporting cleaned fiber material from said
exit to said dryer duct; and
a resin input communicating with said relay pipe for feeding resin therein, the resin being mixed with the cleaned fiber material
prior to the cleaned fiber material entering said dryer duct.
