In the paper industry , Twin roll press machines are utilized for recovering the dissolved materials resulting from the process of transforming wood into pulp and efficiency has a considerable role in wasting resources. The present research was performed for the purpose of showing the effective factors on efficiency by using a mathematical model based on the pattern of simulating the System Engineering Analysis. The Press function was analyzed according to the same principle. Research results show that in a fixed amount of production , the efficiency of washing the twin roll press has a direct relationship with the amount of fresh water and an indirect relationship with the dry percentage of diluted pulp (pulp consistency) in the related Press. The present research shows that the concentrated of soluble materials entering into the Presses has no effect on efficiency, but it is effective in the amount of recovered solution.
