Ulian Project: New Wet Mill

Project Status:Complete
Parent Project:Kintamani Coffee Quality Improvement

Update January 4, 2018: In the years following this project, I have returned to the mill a couple of times to visit and see how things have progressed and I’m happy to report that they have doubled their fermentation capacity as well as built a permanent solar dryer. The solar dryer gives them the ability to dry more coffee on drying racks as opposed to on tarps on the ground. Both of these steps give them the ability to improve the baseline quality and quantity of their coffee with relatively little increase in labor.

fermentation tanks
Two, 1-ton fermentation tanks. The blue tank on the left was the original, built in 2015 and the pink tank on the right is the newer tank.

A big part of the Ulian Project is the new wet mill. As a discrete, private business entity, the mill will purchase freshly picked cherries from farmers and pickers on the spot and process them to be sold as raw, un-roasted coffee beans. There will be a sliding-scale pay grade based on cherry quality; the higher the quality of cherries picked, i.e. the more red cherries, the higher the price paid to the farmer (unfortunately, the decision was made not to pay for higher-quality cherries).

By purchasing the cherries with cash immediately and by paying more for higher quality, we hope to achieve the following:

  1. Get the farmer needed money immediately.
  2. Incentivize the farmers to pay the pickers more

Ulian Mill
The mill, nearly finished. On the left, under the pavillion will be a fermentation tank and where the scales and pulpers will be housed. On the first floor of the structure will be a storage room and the second story will be a small living space.

Salient Achievements

  • The pavilion roof collects rain water that is fed into the water tank.
  • Construction was completed within six months!
  • Overall processing capacity doubled over previous year.
  • Coffee washing machine reduces the number of people needed to wash from 3-4 to 1
  • Improved the fermentation process by implementing starter cultures

Thrust Areas

  • Improve mill hygiene
  • Increase fermentation capacity
    • Increase number of smaller tanks
  • Increase drying capacity

Ongoing Programs

  • Equip the lab/cupping room Their desired quality level does not require a cupping lab
