Cellulose products

Maximum product quality

Production of cellulose and cellulose derivatives requires special expertise with solid/liquid stages as well as appropriate machines and plant components. Our rotary pressure filters (type RPF) and indexing belt filters (type BF) have been used in this application around the world for many years. State-of-the-art machinery and adapted materials enable efficient production of these important products. Our machines meet every requirement, from single or multiple cake washing to steam drying and pressing. These systems are also certified and suitable for pharmaceutical-grade production.

Continuous Pressure and Vacuum Filtration and Washing of Organic Cellulose and Biomass Products

The processing of organic, cellulose-containing materials has been around for many years. Currently, due to high oil prices as well as the significant increase in ethanol usage nationwide from both grain based and cellulosic based sources, there is tremendous interest in developing efficient, cost-effective manufacturing processes to produce energy from cellulosic feed stocks. This article will use actual process data to highlight the choice of pressure or vacuum filtration and cake-washing techniques for these newly developed bioprocesses.
