Density Meter for Cellulose – Densi Dry

DenisDry density meter for cellulose Marrari

Density Meter for Cellulose to optimize the process, production and use of chemicals

What is the moisture meter for cellulose densi dry?

The Density Meter for Cellulose, Densi Dry, is the complete solution for in-line measurement and control for the moisture and density of wood chips for digester feeding in the cellulose production process.

Why is Densi dry a good solution for the cellulose line?

Because with the information of moisture and density of the chip that goes towards the digester, the operator can identify data essences of the process, such as: moisture content/dryness, apparent density and chip volume.

How is densi dry so accurate?

It uses a calibration method for recipes. In short: You use the Tracker (equipment that goes along with Densi Dry) that collects samples during the day and compares them with the laboratory.

If you have divergences, you can go to the included Tracker software and update the values to match the lab test, thus ensuring your accuracy.
