Processing steps of coffee bean in coffee farming

Now, a little bit of information about the processing steps that the coffee bean come to market
Step 1: Harvest coffee berry
Coffee berry grow directly on the limbs of the trees. The wood is very flexible, and thus it is good practice to bend the high limbs within reach. It is important to remove the berries from the branches without removing the stems, as the stems re-bloom each year.

Step 2: Floating the berries
Before peeling, we would dump all berries into a bucket of water. Floating indicates over-dryness or oxygen penetration (likely by an insect). These beans are still edible, just of lower quality.

Step 3: Peel the berry
The coffee farmer usually use hand-crank coffee peeling machine. Pretty straight forward, dump the berries into the top, turn the crank, peeled beans spill out of one side and the fresh husks fly out the other.

Step 4: allow to ferment
The coffee pulper machine dumps the peeled beans into a concrete pit. There, we let the beans sit for 12-24 hrs. The beans are coated in a thin layer of fruit fiber (like a very thin layer of white plum), and thus ferment in their own sugars. I’m not sure exactly what this does, but I know it’s crucial to the final product!

Step 5: Wash, and wash again – and again .
After fermenting, the sugar and fruit fiber layer is useless and thus must be washed completely away. This takes many washings (usually around 6 times ), and much scrubbing of beans.

Step 6: Dry beans
The old fashioned way: use the sun! Each morning for three or so days we would spread the newly-peeled coffee beans on tarps in the yard and gather them up again at night. The dry time varies, based on weather and density of beans laying out to dry. The important thing is not to over dry them! Ready beans will leave a slight indentation when you bite into them, nothing more, nothing less.

Step 7: Hull & Roast!
 Coffee is produced throughout the region and thus there are a couple regional roasting houses utilized by everyone.One extra step done at the roaster, before roasting: hulling a final thin shell off of the beans (pictured).

Step 8: Bag
Carefully weigh out coffee beans, add labels, seal plastic.those packed coffee bean can be sent to market for selling .

if we use some coffee processing machine in those steps ,it will much helpful to reduce the labor of coffee farmer.for the peanut farmer ,peanut sheller machine will be helpful for them.
