Introduction to the treatment of water-washed honey of coffee beans with fruit pulp in the sun

Coffee beans

There are two kinds of defective bean selection methods: manual selection method and mechanical selection method. Manual selection is an assembly line, in which several workers sit on a transmission belt about 1 meter wide to pick out defective beans, and some strict farms will manually select them many times until no defective beans are seen. The mechanical selection rule is to use the computer to identify. To eliminate defective beans is to divide coffee beans into several grades according to the standard. Good coffee beans will enter the selected coffee market, while bad coffee beans will enter the commercial coffee market. Therefore, the taste and quality of high-quality freshly ground coffee and instant coffee are completely different. From the grade of raw beans, we can see that the shelling treatment in front of the gap can only go out to the exocarp and endocarp of the coffee fruit. At this time, the silver skin is still wrapped in the outer layer of the seed. You must use a machine to remove this layer of silver skin. Finally, the coffee raw beans are packed and exported to Yejia Xuefei, but a small number of excellent beans are treated in the sun. If washed Yega Chuefei has a charming fragrance of fruit flowers, and the entrance is like a hundred flowers in full bloom, then the sun Yega is more like a fruit bomb, with its taste buds, the sweetness of fruit syrup and its delicate mellowness, coupled with its charming fruit fragrance, it is no exaggeration to say that the aroma of sun-cured Yega can make you unable to extricate yourself from the aroma of raw or cooked beans.

Silver Skin/Chaff: there is a thinner film inside the parchment that wraps the coffee beans. Because the color is glossy and silvery, people used to call it "silver skin". This layer of silver will fall off during baking. Usually when you grind the coffee, you find some silver crumbs in the coffee powder. These crumbs are the silver skins that fail to peel off the coffee beans during baking.

Coffee beans: each fruit contains 2 coffee beans (except for a single pod bean Peaberry. The fruit of this kind of coffee contains only one coffee bean. Normally, 5% of each batch of coffee beans is a single pod. Coffee beans can be roasted after drying and processing.

Three methods for the treatment of raw coffee beans

We know that the treatment of raw coffee beans can be roughly divided into three types. The distinction between each method is based on the fact that several layers of matter are removed from the fruit before the coffee is dried. The following is a list of the three major processing methods:

11. Natural sun treatment: retain all substances 22. Honey treatment: remove the peel and pulp and retain some or all of the mucous membrane (honey)

(3) washing method: the peel, pulp and mucous membrane were removed by washing and fermentation. This method is also known as the complete washing method (Fully Washed). Shampoo is the most common way for most coffee-producing countries in the world to handle Arabica coffee beans. Some areas also use advanced high-pressure washing machines to clean the peel, pulp and mucous membrane of coffee beans, so fermentation is no longer needed. This method of using a high-pressure washing machine to treat coffee beans is called "natural washing (Pulped Natural)".

From the point of view of the removal of substances and water consumption during coffee treatment, honey treatment is between tanning method and water washing method, as shown in the figure:
