Andritz offers scanChip optical chip analyzer

Andritz AG, Graz, Austria, says its ScanChip analyzer uses image analysis technology for fast, accurate chip monitoring. The basic ScanChip system is designed for off-line (laboratory) analysis. As an option, it can be equipped as an automatic on-line sampler to monitor a continuous chip flow.

The ScanChip system is beneficial for:

• Obtaining accurate and frequent chip quality data so that pulping can be adjusted to match actual chip quality (e.g. using chip size distribution information to optimize cooking control)

• Optimizing the interval between chipper knife changes

• Documenting the quality of purchased chips to ensure proper payments

• Replacing labor-intensive chip sampling and laboratory tests

• Defining chip quality in accordance with testing or mill standards like the SCAN method.

Different chip size distribution methods can be simulated (e.g. the SCAN-CM 40:01standard method). The ScanChip analyzer can process five to 10 chip samples of 10 L/h.

The sample data are stored in the internal database and can be exported to a mill’s DCS or other computer system. A report is generated for each analyzed sample; custom reports can be created to suit a mill’s needs.

Optional measurement modules can be integrated into the ScanChip system. All types of chips, independent of wood species, size or temperature, can be analyzed to provide: accurate, frequent quality data; optimizing intervals between chipper knife changes; quality definition according to standard methods.
