Efficient Drying of Filter Cake (15-35% Dry Solids)
Fuel Options: Natural Gas (NG), Renewable Natural Gas (RNG), Combined Heat and Power (CHP), Propane, or a combination.
Output: Class A Sludge with significantly reduced disposal costs.
The process begins with sewage sludge, sourced from digesters or sedimentation/storage tanks, being transferred into a screw conveyor via a sludge loading container. The sludge is mixed to achieve a higher dry solids (DS) content before entering the dryer.
Hot exhaust gases, generated from gas or biomass combustion, are directed into the dryer’s material dispersal system. This ensures optimal physical conditions for water evaporation, maximizing efficiency and output quality.
Efficient Biomass Utilization: Turning Waste into Valuable Resources
Agriculture, livestock farming, landscape management, and food production processes often generate large quantities of biomass residues. Examples include horse bedding and general livestock bedding, as well as numerous by-products from food production such as grape pomace from winemaking, apple pomace from juice production, fruit pulp from juice and alcohol production, coffee grounds, bakery waste, and more. These residues are typically wet and difficult to handle.
In industries like wastewater treatment and livestock farming, the continuous use of medications increases the risk of harmful substances entering our food cycle. Uncontrolled disposal of these materials can lead to soil over-fertilization and contamination of groundwater.
Our Jumbo Biomass Drying System offers a cost-effective and environmentally friendly solution by transforming waste products into valuable resources. Instead of being discarded, these residues can be reintegrated into sustainable and eco-conscious cycles.
For example, freshly pressed apple pomace is a nutrient-rich by-product but quickly undergoes spoilage and fermentation, producing an unpleasant odor. By integrating our biomass drying system with juice production, wet pomace is dried and converted into high-quality animal feed.
The drying process also hygienizes the material, allowing it to be repurposed as bedding, fertilizer in compliance with fertilizer regulations, or even as a fuel source for energy recovery. This approach not only minimizes waste but also promotes circular economy practices in a variety of industries.
Efficient Drying of Fermentation Residues: Maximizing Value and Sustainability
We dry liquid or pre-pressed fermentation residues to a dry matter content of 90%, utilizing pure exhaust gas from the cogeneration unit—energy that would otherwise dissipate unused into the atmosphere.
Our emission-free drying process significantly reduces existing emissions from the biogas plant, creating a more sustainable operation. Ammonia is fully captured in a closed system, converted into ammonium sulfate, and all nutrients are concentrated in the dried residue. Additionally, the drying process completely sanitizes the material.
Thanks to advanced hot gas technology and the unique design of our system, we achieve unmatched thermal efficiency, requiring only 750 W of energy to evaporate one liter of water. The dried residue is refined into dust-free pellets or granules, making it easy to handle, spreadable, and a valuable commercial product.
Our system also boosts the cogeneration unit’s efficiency to an impressive 92% and operates fully automatically with Active Remote Control (ARC) for seamless performance.
