Apricot's mites

[Ike Rain]

I'm working in a project for processor of nuts and dried fruits. I need
piece of  information, (the missing link), to complete the project.
The scope of the project is simple. We process dried apricots,
specifically Turkish Apricots. These apricots, when we receive them from
the vendor(s), contains, what we think, mites, however, death. To be
sure that we cover every aspect of health and sanitation precautions, we
blast freeze the load of apricots, before we process them. The question
is, at what temperature and for what length of time, we must freeze the
apricots, in order to kill the mites' eggs.
Any one knows the answer?
