Before purchasing, a small sample of the harvest is taken from each producer. This sample is analyzed in the receiving laboratory, undergoing the peeling, sieving, roasting, grinding and tasting processes, which is the same routine followed for large scale production.
The coffee is purchased from small producers in different parts of Brazil. It comes in dry with the hull still on. Different types of coffee are used, which will later be mixed to create specific blends. Each blend produces a different flavor.
After the sample is approved and the product is purchased, it must be received. Each bag received is analyzed to ensure its quality. The coffee is then stored in separate climate controlled warehouses.
Peeling and sieving
After hulling, the coffee passes through two types of sieves that classify it according to size and weight, which results in names like “sieve 14 coffee.” The sieves also remove stones and straw that come in with the product.
For analysis by the selection machines, the beans go through the troughs at high speed. A ray of ultraviolet light confirms the integrity and size of each bean, and compares it to the desired standard. Beans outside the proper standard for consumption are automatically excluded by the machine.
Warehousing in silos and packaging
According to the classification given (relative to the sieve), the coffee is stored in a special silo. Comexim has silos that feed two different production lines, which are totally automated. These lines mix the beans in the proper proportion, as determined by the customer. This process involves transporting the beans, through airborne tubes, to the suspended silos.
Clients and the Blend
Our clients, mostly importers from around the world, require a blend a given blend, which is prepared under rigorous quality control to ensure that the whole batch follows the same pattern. Comexim coffee is delivered as green beans and, in some cases, it may be the ingredient of more blend processes (mixed to other types of coffee) or it may go directly through the roasting, grinding and packaging steps. It will then be ready for trading and consumption.
Loading and shipping
The coffee is ready to be loaded in containers that will transport it by the ton. Large trailers transport the containers to the port of Santos (SP), from where they are shipped around the world.
