ABSTRACT:
An apparatus and method for improving the quality of paper manufactured from recycle paper stock which comprises a hydrokinetic amplifier, a pulper, a dump chest, a cyclone separator, a pressure screen, a vibratory screen and a holding tank. Contaminants contained in the fibrous stock are dispersed and emulsified during the process to produce a better quality fiber stock. The hydrokinetic amplifier generates pressure at its exit while dispersing the contaminants in the fiber stock. The energy possessed in the stock can be utilized to feed the stock through additional treatment devices such as ultrasonic generators and a device for causing the stock to take a tortuous path as it is passed therethrough to further break down the contaminants.
