Advantages and disadvantages of sun treatment and water washing treatment process of water washing treatment

I believe that friends who know about fine coffee are no stranger to water washing and sun treatment, so what is the difference between water washing and sun treatment? At first, the coffee treatment method that people used was the sun treatment method, and the traditional sun treatment method was also the roughest treatment method. Because the processing capacity at that time was backward, the coffee beans were only sunburned on the ground directly, so there were many defects. In order to solve this problem, the water washing treatment method appeared. In order to pursue better quality and stability, I thought of removing the pectin from the peel and pulp of coffee, removing these substances that are easy to ferment and deteriorating, and then drying the coffee beans with parchment, which can greatly shorten the drying time and the quality will be more stable. The cost of washing treatment will be much higher than that of the sun because of the need to set up a washing treatment station in places rich in water resources. The process of washing is as follows: first, the coffee is put into the pool for flotation to remove some immature coffee fruits and impurities, then the coffee fruit is put into the pulp screening machine to remove the skin and pulp, and then the coffee beans coated with pectin are fermented in the fermentation tank, and the pectin is decomposed by microbial bacteria. The fermentation process is about 12rel 48 hours. After fermentation, the pectin will be delaminated with the coffee beans. finally, the coffee beans will be washed with a lot of water and put into a large dryer or drying field to dry. The large dryer can reduce the water content of the coffee beans to 11% in 1 to 2 days. It takes 3 to 6 days to use a thin shop in the drying field, while it takes 7 to 15 days for traditional drying. So what are the advantages and disadvantages of washing treatment and sun treatment? The treatment condition of water washing treatment is more stringent, the flavor is clearer, the acidity is bright, but the sweetness is not as high as the sun, the scope of application of sun treatment is wider, but the defect rate is higher than water washing, and the flavor is more complex.
