Last Updated: 2024/11/03, The washing refining of coffee began in the mid-18th century. In the refining process, the pulp of the coffee fruit is first removed, then the residual mucous membrane on the inner pericarp is removed by a fermentation tank, and the beans are washed and dried. The difference between non-washing refining and water-washing refining is that the non-washing refining method is dried and then the pulp is removed, while the washing method is to remove the pulp and then dry!

The difference between non-washing refining and water-washing refining is that the non-washing refining method is dried and then the pulp is removed, while the washing method is to remove the pulp and then dry!

The washing refining method can remove impurities and defective beans through each step, so the appearance of raw beans is uniform, is generally considered to be of high quality, and the trading price is higher than that of natural drying coffee beans.

However, the more detailed the division of labor, the more procedures for operation and hygiene management, and the higher the risk, so washing is not necessarily equal to high quality. The biggest disadvantage of washed coffee is that coffee beans are easy to catch the bad smell of fermentation during fermentation. some coffee experts point out that a fermented bean will spoil 50 grams of beans. Beans will be stained with the smell of fermentation, most of which are due to the lack of management and maintenance of the fermentation tank. Soak the coffee beans with mucous membrane on the endocarp in the fermentation tank for one night to remove the mucous membrane. However, if the fermentation tank is not cleaned completely, excessive changes in humidity and temperature will cause changes in the microorganisms in the fermentation tank, which will lead to the fermented taste of the coffee.

The cost of washing equipment is high, and the process and steps of refining are also quite laborious, so the production cost is naturally very high!
