Reduce energy consumption and improve process stability from receiving wood to chip cooking. 

 Woodyard is a dynamic environment with varying conditions and often less digitalized when it comes to operator workload and daily decision-making. Smart Woodyard Process Optimization packages fit versatile environments with certain preconditions for adjusting the process accordingly.  

In Smart Woodyard Process Optimization, the complete process area or parts are optimized together with ANDRITZ experts, configuring optimization of the process at the site. Woodyard process optimization comprises the process from wood receiving to chip cooking. 

Maximize yield by debarking optimization 

The purpose of the debarking process is to separate the bark from the wood with the required capacity and debarking result. Often, there is space for improvement in wood loss and energy consumption.

By optimizing the debarking station, it is not only about monetary savings but also about increasing the sustainability and stability of the process by using less raw material in the woodyard and the entire mill. 

Concrete benefit: improved (approx.) 0,5% of yield 

1. The debarking degree is measured (95%), and a setpoint of 92% is set:

2.  The gate position is adjusted from 30% to 35%:

3. Once the setpoint is met by optimizing the debarking process, significant savings are unlocked:
