Description of taste and flavor of coffee and bean washing method introduction of grinding scale production area treatment method

1. Choose beans:

Put the harvested fruit in the water tank, and the ripe fruit will sink, while the unripe and overripe fruit will float up and can be removed.

2, dry:

Put the selected ripe fruit in the square and expose it for 5-6 days until it is fully dry. At this time, the fruit becomes dark brown and the moisture content is 13%.

3, shelling:

After drying, the peel becomes fragile and easy to fall off, and can be removed by machine. Farms run by enterprises usually have their own shelling factories, while small farms are processed by processing centers.

4, selection and grading:

Exquisite farms identify defective beans manually or by machine, pick them out and throw them away. Manual selection usually uses a transmission belt about 1 meter wide, with several female workers sitting on both sides visually picking out bad beans, and some good farms are even selected several times until defective beans are not seen. Machine selection rules use computers to identify defective beans, followed by a grading process that divides coffee beans into several quality grades according to established standards. Good coffee enters the selected coffee market, while bad coffee flows into the commercial coffee market.

The water content of washed coffee is 12% 13%, while that of dry coffee is 11% 12%. General coffee beans show different colors due to their different water content, with higher water content being green or cyan, and less brown or near white. Therefore, the washed coffee beans show a darker green.

Is the silver skin in good condition?

In the process of processing, the washing method usually removes the silver skin from the coffee beans, showing a special luster, but the law of drying and refinement only takes off the coffee shell, and the silver skin is still intact.

Baking degree

Different processing methods use different degrees of baking, the effect is also different. In general, if the water-washed coffee beans have not been deeply roasted, the residual silver skin of the central line still exists. Although the silver skins of dry coffee beans are intact during processing, they are all gone after baking. The deeper the roasting, the darker the coffee beans.
