Washing method

Due to too many shortcomings of the sun method, the water washing method was invented. Water washing is the most widely used treatment method at present, and the biggest difference from the sun method is the use of fermentation to remove the pectin layer.

Treatment process

1. Remove floating beans (same sun method)

Pour the coffee beans into a large tank, the underdeveloped inferior beans will surface, and the ripe and full fruits will sink to the bottom of the water. At this time, the floating beans on the surface will be removed, that is, the steps of removing floating beans will be completed.

two。 Remove the peel and pulp

Through the pulp screening machine (pulping machine), the exocarp and pulp of coffee fruit are removed. It leaves pectin, endocarp and silver peel.

3. Ferment

The purpose of this step is to use biological treatment to remove pectin. Put the coffee fruit processed by the pulp sieving machine into the fermentation tank 16Murray for 36 hours, and the fermentation bacteria will dissolve the pectin.

4. Washing

After completing the fermentation and removing the pectin, the coffee beans will be cleaned again because the fermentation bacteria and impurities will remain on the coffee beans. In order to clean it, this step consumes a lot of water.

5. Drying and removing endocarp and silver peel

The coffee fruit is usually dried by a machine (or sun-dried) so that the moisture content is reduced to 14%. Then use the sheller to remove the remaining endocarp and silver peel, that is, to complete the processing.

Advantages:

1. All the treatment procedures of the water washing method are indoor, so the impurities in the coffee beans can be reduced to the lowest and the quality is the highest.

two。 Since the flesh is removed in the first place, there is no need to worry about mildew like the sun method.

3. The appearance is relatively complete, and the selling image is excellent.

Disadvantages:

1. The procedure is complex and tedious, so the cost is much higher than that of tanning.

two。 A large amount of water will be used, and it will take 40 murmur50 liters of water to obtain 1 kilogram of coffee beans, so it is less used in areas where water resources are scarce.

Flavor:

As a result of fermentation, coffee beans usually have a bright sour and fruity flavor.
