  • The pulping process in a papermaking process for a reconstituted tobacco sheet (RECON) was evaluated. For the practical information, the experiments were conducted in a real mill. Two pulping conditions were chosen and changed depending on the feasibility, such as the pulping temperature and the properties of pulping water. The higher pulping temperature resulted in the easier dissolution of solubles from the raw materials. However, the efficiency of screw press process was decreased by the higher pulping temperature, which resulted in the reduction of the HWS and the concentration in the #1 screw press filtrate. The addition of SEL(Strong extracted liquor) to pulper affected the efficiency of dissolution and the final concentration of #1 screw press filtrate. Although the higher SEL resulted in the less dissolution of the solubles from the raw materials, the concentration of the #1 screw press filtrate was greatly increased by the higher addition of SEL, which could provide much better efficiency to the following evaporation process of the filtrate and could increase the whole productivity.
