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:

1. Natural sun treatment: retain all substances

two。 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 are 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 Pulped Natural silver (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-skinned coffee beans that fail to peel off the beans when roasted: each fruit contains two coffee beans (except for a single pod 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 are dried and processed to bake parchment (Parchment): inside the mucous membrane, a film of cellulose surrounds the coffee beans. When dried, the film looks like parchment, hence the name Mucilage: under the skin and pulp, a thick layer of mucus tightly wraps the coffee beans. Because this mucous membrane is extremely sticky and high in sugar, it is used to call it "Honey". Not only coffee, but also many fruits have a layer of mucus inside. You can check http://en.wikipedia.org/wiki/Mucilage for information about the peel and Skin/Pulp: the outermost layer of coffee beans is covered with berry-like skin and pulp. In addition to the natural sun method, coffee beans treated by other methods must remove the skin and flesh within a few hours after picking. Similar to the cherries we often eat, the difference is that when we eat cherries, we mainly eat the pulp and peel of berries. For coffee, peel and pulp are important by-products. In some places, people use the peel and pulp of coffee to make tea. People in the industry used to call the peel and pulp of coffee "Pulp". The machine used to remove the pulp is called the "desizing machine".
