Manufacturing Process

Harvesting

The first step of coffee processing is harvesting. Around 3 to 4 years after plantation, coffee trees will bear fruit called cherry coffee or cherry. When it is ripe, the cherry will have a bright deep red colour. The harvesting process could by stripping all of the cherries in one time with hands or machine or only harvested the ripe cherries by picking it individually with hands. To prevent spoilage, once cherry coffee has been picked the processing needs to be done as soon as possible. 

Processing coffee cherries

Coffee manufacturing process are vary, based on what kind of product that wanted to be achieved. For Toraja coffee, the processing are natural, washed, and honey.

Wet hulled (Washed/Semi-wash)

Wet hulled process consists of full wash or washed and semi-wash. The difference between these two methods is in the volume of the water that is used. Semi-wash process only used half of the full wash process water.

The cherries are passed through a pulping machine or pulper to separate the skin and pulp from the bean. Then the beans went into the screening process by separating them by weight in water channels. The lighter beans will float on the top, while the heavier ripe beans will sink to the bottom. Then, they are separated by size using a series of rotating drums. After screening, beans then fermented inside water-filled fermentation tanks for 12 to 48 hours to remove the slick layer of mucilage. If the mucilage is separated, beans then rinsed and prepared to be storage by drying them until the moisture content is 11%

Milling

Hulling

When the moisture content of beans reach 11%, the beans are passed through huller to removes the parchment layer (endocarp) for the wet and honey processed beans, and removes the entire dusk husk of the dried cherries for the dry processed beans.

Grading and sorting

Before packed, beans are graded by size and weight. Beans are sized through series of screens by sorted the heavy and light beans using air jet. After that beans are sorted by reviewing for color flaws or other imperfections by manually using hands or by machinery.

Packaging the green coffee

After milled, beans now referred to as green coffee or green beans. The beans then packaged in either jute or sisal bags to be shipped or storaged.

Application

Toraja coffee could be used as single origin coffee or blended with other coffee.
