Qianjie-introduction to coffee tanning and washing treatment

Washing, a technology invented by the Dutch in the 18th century, is the most common processing technology. Water-washed beans currently account for about 50% of all coffee, suitable for rainy areas.

Specific processing flow

As in the first step of solarization, get rid of shoddy beans first.

Then use pulping machine (pulp planer) to remove the peel and pulp of the coffee fruit.

Throw it into the sink to ferment for 16-36 hours, and the fermentative bacteria dissolve the pectin.

In order to remove the residue of fermentation bacteria and impurities, the coffee beans will be washed again.

The coffee fruit is then dried by machine so that the moisture content is reduced to 10% Murray 14%. Finally, the use of shelling machine to remove the silver skin on the coffee beans can be completed.

Flavor: coffee treated by water washing has bright taste, strong sour taste and less impurities because it is fermented into acidic substances in the fermentation tank.

Tanning is one of the most "simple and rough" coffee treatments. There are only three key steps in the whole process: "picking, tanning, and shelling." Sun-treated coffee is one of the most primitive coffee treatments, which has been passed down since it was grown commercially. It seems like a simple method of solarization, but there are many influencing factors.

In principle, the sun-drying method can be carried out as long as there is stable direct sunlight, but the production conditions in many coffee-producing countries are not good, and many farmers can only put their coffee on the ground for sun treatment, thus making the sun-tanned coffee more earthy and onion flavor. as a result, the reputation of long-term sun-dried beans is not good.

When it comes to the advantages of sun-treated coffee, the most obvious is the charming flavor of the coffee itself. In the process of fermentation, the sun treatment retains the pulp and peel of the coffee, which brings charming wine and fruit flavor to the coffee, as well as excellent sweetness and complex aroma.

For many coffee lovers, the most attractive thing about a cup is its charming aroma, while the aroma of sun-cured coffee occupies the attention of consumers. Although the delicious suntan coffee has a charming flavor, explosive aroma and high sweetness, it is also difficult to be treated in the sun.

Knowledge: according to the retention of pectin, honey treatment is also divided into yellow honey, black honey and so on.
