What does a Chip Tester do?
Tests samples of purchased wood chips, used in making pulp, to determine moisture content and quality: Observes dumping of chips into receiving pit and starts conveyor that transfers chips to screening and storage areas. Draws measured sample from conveyor, places chips in drying oven for specified period of time, and records dry weight to determine weight loss. Places additional sample of chips in pilot screen to separate unsuitable wood, such as sawdust, slivers, and oversized chunks. Removes bark from acceptable portion, reweighs sample, and records data on chip quality form. Sweeps and cleans work area. May test samples for acidity and freeness, using standard testing equipment.
