product quality as suggested by the studies above it would appear
that the use of RF for disinfestation will need to be considered on a
product by product basis.
Wang et al. (2006b, 2007a,b) also proposed considerations
about designing and scaling-up plants and processes for industrial-scale post-harvest RF treatment of walnuts, working with
continuous apparatus characterized by high power (up to 25 kW)
and high product load (up to 187 kg of product moving on a belt).
Design and running of industrial-scale RF processes is one of the
main challenges in this field since Wang et al. (2007b) claimed that
many factors (e.g. walnut orientation, differential heating between
open and closed shell walnuts, actual post-storage, and energy
costs) influencing the commercial RF processes must be taken into
account. Energy costs may be comparable to traditional fumigation
ones, but at present the use of RF installations will incur considerably higher capital costs
