Direct product quality control for energy efficient climate controlled transport of agro-material

Synthesis and Humidity Sensing Investigations of Nanostructured ZnSnO<sub>3</sub>

“…Its unique physical, chemical and structural properties may play important role in humidity sensing. Humidity sensors have been important for the accurate control and reliable estimate of water vapours content in atmospheres from industrial processes to the general improvement of the quality of life [7][8][9][10][11]. Generally a humidity sensor has to possess fast response, high sensitivity, negligible hysteresis over periods of usage and possibly a large operating range for both humidity and temperature.…”

Prediction of postharvest firmness of apple using biological switch model

“…Using the fitted model parameter set, we have validated the model using experimental data on delayed CA storage of Elstar apple. After its initial development (van der Sman and Sanders, 2005), the validated model has proven to be a valuable tool to design new control strategies for the transport of fruits and vegetables (van der Sman and Verdijck, 2003;Verdijck et al, 2005), rendering very significant energy savings.…”

Modelling ventilated bulk storage of agromaterials: A review

“…proposed a model for product quality in the processing of agro-materials for process control purposes, but did not design a matching controller. Verdijck et al (2005a) used the model of to design and test an energy-efficient product controller on base of optimal climate conditions, but is not test it on (potatoes) storage facilities. Verdijck et al (2005b) came up with a model-predictive controller, based on a lumped parameter model.…”
