Blanching Peanuts Processing

1. Receiving and Storage of Raw Peanuts

A) Raw Peanuts Receiving.
After the trucks go into OLEGA´s facilities, we proceed to unload the goods, which are received with the corresponding chemical and physical analysis done by our laboratory.

B) Cold Storage of Raw Peanuts.
The raw peanuts are stored in the cold warehouse, according to its characteristics; waiting to be used for the blanching process or for the consolidation process, according to our customer´s requirements.

2. Main Process of Blanching

A) Heat Treatment.
Once we selected the peanuts parcels to blanch, they go into a furnace with determined temperature and maximum preset time. This process aims to reduce grain moisture, so the skin can be removed easily in subsequent stages.

B) Blanching.
This stage involves the removal of the skin that covers the peanuts. The grains from the furnace go through the peelers, which have rollers cover with abrasive material allowing the skin extraction.

C) Electronic Selection.
This step consists in the removal of damaged grains, with remaining of attached skin and foreign material, by a grain comparison with the standard colour parameter.

D) Final Inspection.
Peanuts from the electronic selection enter a final inspection by human factor specialists, minimizing the foreign material that may go into the finished products.

E) Detection and Rejection of Metals.
Peanuts go through a metal detector that performs the separation of metal, removing them to a rejected flow.

F) Packaging of Final Product.
The big bag packaging process is made in the production line by direct filling of gravity action. It can also be packaged bags. Blanched peanuts are ready for export.

3. Delivery of Finished Product.

A) Load and Delivery of Finished Products to Customers.
We proceed to the containers consolidation of blanched peanuts.
