The bags of green coffee can be
delivered in different forms:
Loose (in cisterns or containers)
In bags on pallets with 25
pcs
In loose bags to unload with a mechanical hand or with a telescopic conveyor belt
followed by the bag cutter and empty bag press
When bags are unloaded, the
operator informs the system of which type of coffee is being unloaded by entering the code
and destination using the electronic panel located in this area.
The bags are then cut (manually or automatically) to start the emptying procedure.
The system protects against different products being loaded into the same silos, unless
specific instructions for this are given.
The green coffee unloading system has been functioning at many of our customers’
plants for over 10 years. Scolari Engineering has learned a great deal about how to reduce
errors made by the operator and is capable of managing batches and their traceability.

BATCHING
After being
cleaned and selected according to size and density, the coffee is weighed (net weight) and
sent to the designated green coffee silo.
Subsequently, the operator chooses the product to be treated from a blends (or qualities)
menu pre-programmed into the computer.
This pre-programming is very simple, easy to modify, and can be learned in few hours.
After selecting the blends, the operator enters a few variables, such as the amount of
roasted coffee to be produced, the roaster to use, the sequence and the destination of the
batch.
When the batch reaches the roaster, the appropriate roasting curve is set automatically by
the product or blend code.
