Each NCD(non-contact drying) equipment has its own advantages, drying process should follow different applications, it is not easy to have all benefits together. Voith developed this configuration by compact design and precision energy recovery process, and it is helpful to produce a perfect coating layer on the paper, as well as minimize energy consumption.

The pulp at first stage refining was divided into shives and pulp A with the use of shives screens, the shives were refined to the pulp B with different freeness, then the pulp B was backfilled into pulp A in proportion, the effects of selective refining on the paper properties and energy consumption of refining were analyzed. The results showed that: selective refining could reduce the energy consumption of refining. On basis of the freeness of the resultant pulp was the same as with the self-finished pulp, when the freeness of pulp B reached to 170 mL, the freeness of pulp C is 305 mL, energy consumption of refining decreased by 13.1%, paper bulk and tear index increased by 11.6% and 1.7%, while the tensile strength and internal bonding strength decreased by 10.5% and 16.8%. The selective refining of shives could adjust the paper properties by controlling the shives refining characteristic.
