Two different walnut huller-dehydrator facilities near Stockton,
CA, owned by the same company, collaborated on this project. The
facility sampled in 2011 (trial 1) was a small, pilot-scale operation
(processing approx. 4500 kg/h) (Fig. 1), and the facility sampled in
2012 (trial 2) was a full-scale operation (processing approx.
45,000 kg/h). All samples were evaluated in an on-site laboratory
located at the smaller huller-dehydrator facility.
