Introduction of half-sun method for the treatment of raw coffee beans

In order to improve the quality of coffee in Brazil, the Brazilian government has invented half-sun method and vigorously promoted it. At present, almost all high-quality coffee beans in Brazil use half-sun method to treat raw beans. It can be said that half-sun method has successfully improved the overall quality of Brazilian coffee.

The pre-treatment method of half-sun method is almost the same as that of water washing.

Choose beans: first put the coffee fruit into a large water tank, remove the floating fruit, and then put the sunken fruit into the pulp sieving machine to remove the pulp. To better remove the immature fruit, it is more important to let the coffee beans dry in the sun no longer with pulp, but only wrapped in a layer of pectin, which is more helpful to control the subsequent fermentation process.

Drying: move the beans to the bean drying farm to dry, about 3 days to achieve a certain degree of dryness

Drying: further drying in a dryer until the water content of the beans reaches 10.5% to 12%.

Polishing: the final polishing process is carried out before the beans are bagged and exported.

Because the half-sun method has certain requirements for climate and technology, it can only be widely used in Brazil. Through half-sun treatment, it not only retains the unique sweet taste of the sun method, but also avoids the mildew taste of the sun method, shaping the unique flavor of Brazilian coffee.
