    Green energy incentives

    Governments across the globe are setting up green energy incentive schemes aimed at utilising residual heat from pyrolysis, syngas and biogas (CHP). With political organisations committed to reducing carbon emissions, several schemes have been initiated to help bring renewable technology to the market.

    Adding value to by-products

    Using FlowDrya, clients can add significant value to low value by-products while optimising waste heat utilisation:

    • Sawmills with wet wood chip for conversion into dry, renewable biofuel.
    • Estates with available forestry or timber to be chipped, dried and sold as renewable biomass boiler fuel.
    • Timber product companies with off-cuts for transformation into biomass fuel.
    • Clients with wet paper pulp who can dry paper making residues into valuable animal bedding.
    • Poultry houses with under-utilised poultry manure for conversion into substitute fuel or fertiliser.
    • Recycling companies with waste wood who can increase their financial income working as a dry wood chip fuel supplier.

    Simplicity is paramount

    Every Stronga product is designed to comply with our core principle of only building simple, easy to operate machines.

    FlowDrya GS positively moves wet materials from a hopper, along a hydraulic-powered moving drying floor, and over a flow of temperature-controlled drying air which is fed from the Heatex air control module.

    FlowDrya drying is incredibly simple, highly reliable and powerfully effective.

    Optimal airflow injection

    The injection of drying quality air through the wet materials as they flow along the drying bed optimises the evaporative drying process to reduce moisture content to a desired level.

     

    1. Drying air in. Drying quality airflow is fed by the Heatex air control module. Air can also be injected from other residual process air sources.
    2. Sub-floor air plenum. Warm Heatex air flows into the sub-floor air plenum, interacting with the steel infrastructure. Hot steel conducts thermal energy directly into materials to supplement drying.
    3. Moving floor drying. Warm air rises through the ventilated drying floor to diffuse through tumbling wet materials, efficiently inducing evaporative drying. Full length diffusion delivers an even distribution of airflow along the drying floor.
    4. Exiting process air. Exhaust airflow is dissipated into the atmosphere, ducted via optional roof and flue equipment, or recirculated via energy-recovery, cross flow FlowFilta. Click here to see the Stronga FlowFilta product page >

    PulseWave™ mixing motion

    Highly efficient PulseWave™ thoroughly mixes and progressively dries materials on the moving floor. PulseWave™ ensures that every part of the material interacts with the drying bed and receives an even airflow, leading to uniformity of dryness.

    PulseWave™ forward-stroke

    Materials are shifted forwards by the pushing blade face, causing a driving force low to the bed. The driving force is weaker above the pushing blade, causing materials at the wave’s crest to lag and tumble onto the drying bed behind.

    pulsewave mixing motion flowdrya gs FlowDrya GS

    PulseWave™ back-stroke

    Materials are lifted over the tilted axis of the blade to form another wave. As the crest height grows, the wave becomes less stable, causing materials to tumble forwards and backwards.

    DryStation™ Siemens PLC

    FlowDrya operations are managed by the integrated DryStation™ Siemens Programmable Logic Controller (PLC). The PLC system, working in total synergy, maximises efficiency and reliability while reducing time and management costs.

    Remote access

    The illuminated 7″ DryStation™ touchscreen acts as the interface between the PLC system and FlowDrya. The DryStation™ screen enables instant visual access to the controls and safety parameters. Low maintenance PLC systems have durable infrastructures designed to withstand temperature variations.
