Plant modernizations continue for wood-based panel producers

Dieffenbacher particleboard forming station.

Dieffenbacher is collaborating with customers on modernization projects. One recent example is the retrofitting of a steam preheater at Pfleiderer’s MDF plant in Baruth, Brandenburg, Germany. The companies’ collaboration led to Dieffenbacher’s EVOsteam technology. Installed directly at the press infeed, the EVOsteam preheats the mat by injecting steam. This reduces the time needed to heat the mat inside the press, accelerating production.

EVOsteam can also be used in particleboard plants. To boost its particleboard production in the province of Long An, Vina Eco Board Co. Ltd. of Vietnam is also equipping its line with the new Dieffenbacher steam preheater.

Vina Eco Board also commissioned Dieffenbacher to convert the forming station of the same line. By installing roller screens in both wind formers, spreading accuracy is reported to be improved, leading to better surface quality of the produced boards. Installation and commissioning of both modernization projects are scheduled for summer or fall 2021.

Another forming station conversion is underway for Pfleiderer at its Grajewo site in northeastern Poland, where it produces MDF and particleboard. To meet increased demands for particleboard surface quality, Pfleiderer worked with Dieffenbacher to develop a surface layer forming process. With a design adapted to the airflow, the new forming station accommodates shorter, space-saving wind formers. The project is scheduled to go into operation as early as next spring.

In addition to offering custom conversion packages, retrofits, component exchanges and plant extensions, Dieffenbacher develops custom systems for performance optimization, the integration of modernization solutions into existing processes, and the automation of existing plants. Dieffenbacher also relocates plant components or complete plants for its customers and partners.
