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.
Digester operators, or cooks, cook wood chips with soda ash or acid to separate the wood pulp from unwanted constituents. They test the resulting solution.

4 competencesconcentrate pulp slurry
Measure the weight and concentration of the pulp slurry for further processing and storage by using disk filters and calculating slurry density with specific formulas.
monitor pulp quality
Ensure quality of recycled papers and pulp, reviewing stickies, plastics, colour, unbleached fibres, brightness, and dirt.
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.

8 competencesdrive chipper truck
Drive chipper trucks or vans, from which the machine is often controlled and operated. Use the vehicle for pickups of processed wood materials in forest job sites.
monitor chipper machine
Monitor in-feed and clear the chipper equipment of debris to avoid blockages and jams in order to secure a free flow of materials.
operate debarking machine
Set up and monitor the machine that strips remaining bark from timber or logs before they can be further processed, for example chipped for pulp production.
operate wood chipper
Operate wood chipper machine by inserting long logs, poles, and pieces of timber, producing wood chips.
prepare wood production reports
Prepare reports on wood technology production and progressive development of wood based materials.
tend bleacher
Add the required amount of bleaching substances and additives and operate the bleaching part of the paper machine, which bleaches the pulp with liquid and solid chemicals, removing any remaining lignin and other impurities.
test paper production samples
Acquire test samples at various stages of the paper deinking and paper recycling process. Process the samples, e.g. by adding a measured amount of dye solution, and test them to determine values such as the pH level, the tear resistance or the degree of disintegration.
green
use deinking chemicals
Handle surfactants or deinking chemicals, which remove ink from fibres. Chemicals such as hydroxides, peroxides, and dispersants are used in processes such as bleaching, flotation, washing, and cleaning. Amongst these non-ionic and electrolyte surfactants are the most important.
