What is the DensiDry moisture meter for pulp and Cellulose?

DensiDry is Marrari’s solution for controlling the moisture, volume, and density of wood chips used in the pulp digester for the production of various types of paper. With it, you have essential data for dosing chemicals to remove lignin and facilitate and secure work closer to the desired KAPPA value for that line.

Why is DensiDry a good solution for the pulp and Cellulose line?

With the provided information—humidity or dryness, apparent density, volume, and mass of chips—the operator can precisely control the digester process, resulting in better utilization of wood, stability of the KAPPA number, reduction in process chemicals, and also in bleaching chemicals.

Benefits:

Using an integrated system of real-time volume/flow meters, a moisture meter, and a density meter in pulp production can offer several significant benefits. Here are some of them:

  • Production Process Optimization:
    • Real-time meters allow immediate adjustments to the production process based on accurate data, optimizing operational efficiency.
  • Quality Control:
    • The moisture meter provides crucial information about the raw material’s humidity, ensuring it meets the necessary standards for high-quality pulp production.
  • Energy Efficiency:
    • The volume/flow meter helps optimize fuel consumption, avoiding overfeeding or underfeeding, contributing to energy efficiency and cost reduction.
  • Waste and Cost Reduction:
    • Precise measurement of volume and density helps avoid raw material waste, reducing production costs and minimizing waste generation.
  • Maximization of Pulp Production:
    • By controlling humidity, volume, and density in real-time, it’s possible to maximize pulp production, making the most of available resources.
  • Environmental Compliance:
    • Precise control of process parameters helps reduce environmental impact, minimizing unwanted emissions and waste, aligning with stricter environmental standards.
  • Prevention of Operational Issues:
    • Rapid detection of parameter variations allows for the immediate identification and correction of operational issues, reducing the risk of unplanned shutdowns and increasing process reliability.
  • Operational Safety:
    • Meter integration can also contribute to operational safety, identifying deviations that may pose risks to workers’ health or equipment damage.
  • Real-time Analysis:
    • The ability to conduct real-time analyses provides valuable insights for strategic decision-making, improving overall production efficiency.
  • Predictive Maintenance:
    • Continuous monitoring of parameters allows the implementation of predictive maintenance practices, reducing costs associated with corrective maintenance and maximizing equipment availability.

In summary, the implementation of these real-time meters in pulp production not only improves process efficiency and quality but also contributes to a more sustainable and effective operation.

How is DensiDry so accurate?

It uses a calibration method based on recipes. In short: you use the Tracker (equipment that comes with DensiDry) to collect samples during the day and compare them with the laboratory.

If there are discrepancies, you can go to the Tracker’s included software and update the values to match the laboratory assay, ensuring its accuracy.
