In Japan where we cannot expect much natural resources, the utilization of waste paper is quite active and various kinds of technology have been developed. On the other hand, the necessity of recycling the resources is widely urged due to the threat of global warming. Under the circumstances, the utilization of waste paper has been accelerated and now further advanced disintegrating technology to enable the usage of the waste paper which has been abandoned as waste before is keenly expected.
We, Taizen, have been developing the technology for the treatment of waste paper such as the disintegration of waste paper pulp and softening and resolving foreign materials in applying our own kneading technology. And, recently, we have succeeded in the development of totally new model of vertical separator washer, “Vertical Z (Zekoo) ”.
“Vertical Z (Zekoo) ” has various unique functions in comparison with the conventional horizontal washing machine. The pulp slurry to be washed theoretically moves from the lower side to the upper side, and the fiber and the impurities are separated efficiently through rotating cylindrical screen.
Installation space required for “Vertical Z (Zekoo) ” is 1⁄9 only compared with the conventional horizontal washing machine. In addition, the area of the required screen surface can be reduced to 1⁄3, the volume of consumed water can be reduced to 1⁄4 and electric power can be reduced to 1⁄4. Brightness of the pulp can be improved after washing by “Vertical Z (Zekoo) ” and, in addition, the improvement of the yield can be achieved.
Furthermore, the screen of “Vertical Z (Zekoo) ” has been used for approximately9years without replacement and the expenses for the maintenance can be minimized.
We will keep developing the original and unique technology.
