Doh-Ei Paper, Japan, has started up an Andritz (Graz, Austria) PrimeDry Steel Yankee (3.7 m dia. and 4.3 m shell length) at its Hokkaido mill in Japan. The successful startup is the first for a Steel Yankee in Japan. Doh-Ei produces 4,500 metric of facial tissue and 14,500 metric tpy of toilet tissue from 100% recycled paper.
In June 2011, Doh-Ei commissioned Andritz to upgrade its drying line. In addition to increasing production and improving runnability of the tissue machine, the investment also was made to reduce energy costs, a particularly important criterion due to the sharp rise in oil and gas prices.
"Steel is a highly heat-conductive material. Following the installation of the Anditz PrimeDry Steel Yankee, the energy efficiency and production output of our mill will be very high," said Masashi Kobayashi, president of Doh-Ei (photo on right).
