One of the most important operations in a packing line is sorting
(including sizing). Such an operation requires several parameters
to be quickly identified and managed at the same time. These
include variety, maturity, color, shape, size, and defects. The efficiency
and effectiveness of the sorting govern the quality standard
of the packing lines and product (Office of Thai Agricultural Commodity
and Food Standard, 2003), which in turn determines the
marketability of the product. Accordingly, there is need for a robust,
consistent, rapid, and cost effective sorting method.
Manual sorting continues to be the most prevalent method
used. Problems inherent in this system include high labor costs,
worker fatigue, inconsistency, variability, and scarcity of trained labor.
The paucity of available labor and increasing employment
costs during the peak harvesting seasons have been identified as
the important factors driving the demand for automation of the
industry.
