The coffee is mechanically processed at UNICAFÉ´s warehouses by machinery responsible for the following activities.
Beans are separated and graded according to size. This is traditionally done with grading sieves 14, 15, 16, 17, 18 and Mocha. In a nutshell, this is what is known as the coffee grading process. Larger beans are more commercially valuable than smaller ones.
SORTING AND VENTILATING
Electronic machinery separates healthy from flawed coffee beans through the use of photocells which sort them by color (black, green, foxy or brown).
The beans are also mechanically separated by weight. The lighter, flawed beans (broken, CBB damaged or broca, shell, etc.) are sorted out. This step makes use of highly advanced technology, which ensures accuracy in the final product, which will then be packaged and shipped to the consumer.
LOADING THE PRODUCT
There are, typically, three different ways to package export coffee. At UNICAFÉ, this is done according to the requests and infra-structure of each importer.
COFFEE READY FOR EXPORT
60 KG JUTE BAGS: these are the traditional coffee bags. A 20-foot container can hold approximately 20 bags.
BULK CONTAINER: containers specifically tailored to transport coffee. They are lined with special wood and with polypropylene liner bags; the capacity is equivalent to 360 bags. This is the most commonly used process today, as it is the most cost effective one of all.
BIG BAGS: polypropylene bags which are equivalent to 20 bags.
