How is the Supply Network Structure for Brazilian Peanuts?

Brazil exports around 40% of its peanut crop annually. Peanut production is centered around serving the domestic market first. Virtually all exports are as peanut kernels, and very few peanuts are exported in-shell.

After peanuts are harvested, they are cleaned and processed. Thereafter peanuts are kept in storage (warehouse facilities) until orders are received. 

The harvest to export order summary is as follows:

Harvest -> Washing -> Mechanical Dehusking -> Gravity table -> Grading & Densimetric table -> Sorting by color -> Packaging -> Storage -> Aflatoxin levels analysis -> Shipment
