follow site Walnuts are brought to our processing plant where the outer green husk is removed by our huller and the nut is mechanically dehydrated (air-dried). The walnuts are graded into two distinctive markets, inshell and shelled. Inshell walnuts are sized as jumbo, large, medium, or baby according to USDA standards. Shelled walnuts are mechanically cracked. Kernels are screened into a series of sizes, and moved through electronic color graders and shell sorters. Finally our shelled walnuts are hand-sorted by trained sorters and certified by on-site USDA personnel.
