Wet residues to dry revenues

MultiDrya batch drying systems are well proven to transform your wet waste residues into dried revenues. Discover the key benefits of this batch drying system:


  • All-in-one batch dryer. Simple batch loading, drying and onward processing of wasted wet residues.
  • Reduced dust environment. Large drying surface area delivers a low pressure environment, helping to reduce dust.
  • Tried & tested moving floor. Well proven, robust, long life twin moving floor arrangement, designed for non-free flowing bulk solids.
  • Monocoque, mobile structure. Modular, plug & play construction can be located internally, externally or easily moved between sites.
  • Energy-efficiency. Low electrical energy requirement batch drying system, operating for low hours even in high operational situations.
  • Weigh system. Instant, knowledge-building indication of evaporation over time, allowing emptying based on an optimum target weight and moisture content.

    Every hour counts

    Cost savings and extra income from added-value calorific fuel add up, every hour, especially in high duty situations.

    Robust and reliable MultiDrya has no belts, chains or sprockets and very few moving parts. With simplicity comes reliability, and with reliability comes low service and maintenance costs and maximum uptime.

    Take control of drying efficiency, every hour, with MultiDrya’s smart PLC console.

    Incredibly compact. Exceptionally efficient.

    Incredibly compact and space-saving while maintaining exceptional throughput efficiency.


    • Excellent time efficiency. Because of the high loading capacity, you can simply load the batch dryer once and then leave it unsupervised for long intervals before it empties.
    • Material efficiency. Extremely efficient batch drying on CHP plants for use with a wide range of wet materials. Imagine how you could use this direct feeding, batch drying floor to dry wood chip, waste fractions, SRF, RDF and much more.
    • Highly productive batch dryer. High duty cycle due to a simple, robust and long life modular construction, allowing for reliable high production over long periods of time.
