The Design Concept of the Saving Energy for OCC Screening System

Abstract

Customers’ trials of stock preparation conducted by the VIPT’s Technology Center were, except large-scale pilot equipment, mainly performance tests and single process simulation of the single equipment until around 1988. However, recent test mainstream, in the both paperboard and paper fields, turn to be the test to verify the improvement of quality deteriorated by change of raw material quality, improvement of productivity, reduction of production cost, and quality improvement required by end users.
Regarding quality test, customers are more concerned about detailed areas such as adhesive-related contaminants, dirt and flake than in the past. Therefore, highly technological systems optimizing a single equipment performance are strongly being required by customers.
Customer requirement for high quality product being more and more intensified and the difficulty in recycling of waste paper being expected, we need to enhance our technology to be able to respond to these changes of industry’s situation. Additionally, in order to develop the “Post-Recycle 60”, we VIPT are willingly ready to cooperate with this trend.
This time we would like to introduce our development concept of OCC Screening System with the focus on achieving energy saving and quality improvement at the same time.
