What is the fastest way to pick coffee beans-roast coffee beans in the oven

It has been calculated that the cost of harvesting a plantation or farm is half of the total cost of the year. In Brazil, people have tried many times to use mechanical picking to reduce these costs. The machine shakes branches across the coffee tree so that berries that become loose because they are ripe will fall into the funnel star. But this can only be done in places where natural conditions are better, and they need to be high-speed in advance, because the machine can only be used where the trees can be planted in rows and rows, and the coffee beans picked by the machine need to be checked afterwards to pick out the leaves and branches that have fallen in the funnel. It is troublesome to pick in this way.

In areas with relatively high elevations, such mechanical picking method cannot be adopted, and manual picking must be used, which requires a large number of seasonal workers. Pickers should also be careful not to pick unripe, bad or overripe coffee beans, as they will affect the overall quality of the coffee harvested. The original picking method ensures the quality of coffee bean picking to a great extent. Those coffee beans that are not so good are classified as "ordinary", "sour" or "fermented", and the last one is very bad.

Picking: usually picked by machine.

Drying: you can use sunlight to dry the fruit, or use a dryer to dry. Store in the cellar when the humidity reaches 12%.

Shelling: use a special sheller to remove the fruit shell.

Polishing: coffee beans retain the silver skin on the outside of coffee beans before they are exported. It will be removed only after the export order is placed and can be shipped abroad after polishing.

Coffee beans processed by this process are called "dried beans", or "natural beans".

Picking: most of them are picked manually. Only ripe coffee berries of similar size are picked so that the peeling machine can handle them.

Cleaning: soak the coffee berries in water in order to remove overripe coffee berries. Coffee berries that are not ripe enough will be removed in other ways.

Peeling: after the coffee berries are softened in water, they are treated in a peeling machine, and some of the flesh will be removed.

Remove pulp: remove the flesh artificially and rinse with a lot of water in the cement ditch.

Clean the mucous membrane: put the coffee beans in the cement ditch again and wash the mucous membrane on the surface of the coffee beans with water.

Soak screening: soak the coffee beans in water to remove the overripe coffee beans floating on the surface.

Drying: exposure to the sun for one to three weeks, or machine drying, reduces the water content of coffee beans from 50% to less than 12%.
