The difference between mechanical picking and manual picking of coffee beans-starting from Hawaiian coffee

The difference between mechanical picking and manual picking of coffee beans

two。 Hand picking

Selective picking, that is, walking several times between trees and picking only those ripe red berries at intervals of 10 days. Higher quality coffee beans are used. It is divided into three categories:

1. The method of rubbing branches: the harvester wears a basket at the waist, straightens the branch, and uses the mobile phone to rub along the branch from the bottom to the top, so that all the fruit on the whole branch falls into the basket.

2. The method of shaking branches: the harvester shakes the trunk hard so that the fruit falls to the ground and then picks it up in the basket.

3. Manual harvesting method: only pick ripe fruit and put one grain in the basket.

(the selected coffee is picked manually and picked for 3-6 times)

Advantages: the picked coffee fruit is uniform in size, similar in maturity and free of other impurities, which is beneficial to post-processing.

Disadvantages: high cost

one。 Mechanical picking

Mechanical picking is suitable for coffee gardens with flat land and large areas of plantation. afterwards, it is necessary to check the coffee beans picked by the machine and pick out the leaves and branches that have fallen in the funnel. This method is often used in Brazil.

Advantages: low cost and high efficiency

Disadvantages: automated machine harvesting will harvest branches, leaves and other sundries, and ripe and immature fruits will be picked. In this way, there will be no good quality.

1. Raw bean treatment: washing, honey treatment, sun treatment, but no matter which treatment method is to remove the pulp to get coffee beans, as for the use of different treatment methods are related to the treatment cost, demand and taste, you can learn more about it yourself.

2. Baking: the process from raw beans to cooked beans is also a key step for coffee beans to have that aroma. This process will be relatively technical, and if you want to involve it, it will require a lot of practice over a long period of time.

3. Grinding: the process of turning coffee beans into coffee powder must be a prelude to more uniform and moderate extraction

4. Extraction: if you use an Italian coffee machine, you can add milk to make lattes, kabs and other kinds of coffee after the process of getting Espresso. If it is other utensils, you can get different coffee liquid.
