Understanding walnuts’ engineering properties is important to facilitate and improve the design of processing equipment as well as harvesting, packaging and storage procedures and facilities.
During the process of extracting of the oil from the walnuts and its derivatives, the kernels undergo a series of unit operations.
At each step, various types of cleaning, grading, separation and oil-extraction equipment operate on the basis of the walnuts’ mechanical properties.
Therefore, detailed findings reported in some studies provide useful data to be used by engineers in the design of suitable walnut processing machines, thus enhancing process and quality control.
