digester operator
Role lens
Are you interested in a skilled technical role involving chemical processes and quality control? As a digester operator, you play a vital role in separating wood pulp from other materials, contributing to the production of paper and related products.
Digester operators, sometimes referred to as cooks, are responsible for operating industrial digesters – large vessels where wood chips are processed using chemicals like soda ash or acid. This process separates the wood pulp from unwanted components. The role involves monitoring and adjusting chemical mixtures, controlling temperature and pressure, and regularly testing the resulting solutions to ensure quality and efficiency. It’s a hands-on position requiring attention to detail and adherence to safety protocols.
- • Operating and monitoring digester equipment to ensure efficient wood pulp separation.
- • Testing and analyzing solutions to verify chemical composition and pulp quality.
- • Adjusting chemical mixtures, temperature, and pressure according to established procedures.

-
types of digesters
This includes the stationary and rotary steam digesters, which cook wood chips in an acid solution to make pulp for use in the manufacture of paper.
-
types of paper
The different criteria used to determine differences in paper types such as coarseness and thickness, and the different fabrication methods and wood types from which the types of paper stem.
-
types of pulp
Kinds of pulp are distinguished based on their fibre type and the specific chemical processes through which they were created.
-
deinking processes
Various deinking processes such as flotation, bleaching, and washing. These are used to remove ink from the paper in preparation for producing new paper.

- types of wood
- types of bleach
-
work safely with machines
Check and safely operate machines and equipment required for your work according to manuals and instructions.
-
monitor automated machines
Continuously check up on the automated machine's set-up and execution or make regular control rounds. If necessary, record and interpret data on the operating conditions of installations and equipment in order to identify abnormalities.
-
supply machine
Ensure the machine is fed the necessary and adequate materials and control the placement or automatic feed and retrieval of work pieces in the machines or machine tools on the production line.
-
operate digester machine
Add cooking chemicals and steam to dissolve lignin and separate the plant fibres, breaking down wood chips to recover pulp after a bleaching and drying process.
-
wash fibres
Remove the chemical solution of the digesting process, making paper pulp soft and fibrous.
-
concentrate pulp slurry
