CO2 monitoring in the potato industry
08 October 2016
Techmark, developers of custom air-handling systems that monitor, control and distribute air to specification in potato storage facilities, recently worked with a major North American snack food processor to improve the process quality of its chip potatoes shipped by rail.
The rail cars were not ventilated, and over several days, CO2 accumulated to levels that could adversely impact fry quality of the potatoes.
According to Techmark installing Vaisala GMD20 transmittors led to improvements in ventilation control with positive results realised on the fry quality of potatoes shipped by rail.
If a grower's potatoes do not meet the processor's quality standards, typically a defect rate of 15% or less, the grower may need to seek other lower paying markets for the potatoes.
