Coffee shell is the residue left after coffee cultivation and the waste left after coffee brewing is called coffee grounds, in addition to coffee peels, coffee grounds and coffee powder. Coffee shell is a kind of biomass waste, which can be processed into pellets through a coffee husk pellet machine or coffee husk pellet production line, which is mainly burned as biomass energy.
Coffee has a huge demand in the market and hence it is produced widely in different parts of the world like Brazil, Vietnam, Indonesia, and Colombia. The coffee husk that is left behind after the cultivation of coffee can be converted into an extremely valuable fuel, which is known as the coffee pellet. Coffee pellets are becoming important sources of energy which are used for the generation of electricity.
While some of the world's top coffee-producing nations are well-known, others may come as a surprise. More than 70 countries produce coffee, but the majority of global output comes from the top five producers: Brazil, Vietnam, Colombia, Indonesia, and Ethiopia.
1. Higher heat value
There are 52.2kg of carbons in every 100kg of coffee waste ground,which contributes to the high heat value of coffee pellets,reaching more than 4200mj/kg.While the wood pellets normally has 4200~4300mg/kg.
2. Lower cost of raw material
Coffee grounds normally comes from individuals,shops and factories,they throw way those coffee ground.So the cost of coffee waste ground is lower than others.
3. Cleaner property
Unlike other biomass raw material,coffee ground is coming from coffee beans,which must be pre-processed so that both the finished product and byproduct are clean and have no harm to human body.
4. Short growing period
When raw material is wood type,the growing period of trees is about 4 year,while coffee bean only takes half of a year.That means you can get coffee waste material more easily.
How to Make Coffee Shell Into Pellets
1.Advanced gear-driving system with motors on this coffee husk pellet machine, stable and reliable.
2.Adopting high-qualified components on this coffee shell pellet mill, with stable performance, long service life and low noise.
3.Whole transmission parts (including motor) of this coffee husk pellet making machine chooses high-quality SKF bearings to ensure the transmission efficient, stable, low noise. Main motor choose Siemens.
4.This coffee husk pelletizer is equipped with full single layer stainless steel feeder, forced feeder, ring die and cutter .
5.Adopting international advanced technology on this coffee husk pelletizing machine: German gun drill and vacuum furnace heat manufacturing process in ring die making to ensure the pellets smooth and of high quality.
The coffee husk pellet press machine process: crushed coffee husk material is fed evenly by the forced feeding device, the centrifugal force generated by the rotation of the ring die, and the action of the feeding scraper. The two pressing areas in the ring die are in the wedge-shaped space formed by the two press rollers and the ring die.
Under the strong squeezing action of the pellet making machine ring die and the press roller, the coffee husk material is gradually compacted, squeezed into the die hole of the ring die and shaped in the die hole. Because the extrusion of the material between the die and the roller is continuous, the formed coffee husk material is continuously discharged from the die hole in a columnar shape, and then cut into coffee husk pellets of the required length by the cutter, and then enters the next coffee husk pellet production line process.

Step 1: Grinding
Coffee husk is crushed with the help of coffee husk hammer mills or a coffee husk grinder to reduce the size of the coffee shell and finally produce a fine powder.
Step 2: Drying
Coffee shell has a high moisture content of 40-70%, depending on the olive oil extraction process. Then a rotary drum dryer is essential. The rotary dryer has a slight inclination, acting as a conveying device and stirrer. The goal of the drying process is to reduce the moisture of coffee shell to approximately 12%, which is suitable for pelletizing.
Step 3: Pelleting
After drying, the coffee shell can be pelletized directly without any further treatment. The ring die coffee shell pelleting machine is more proper for coffee shell pellet production. And the ring die compression ratio should be higher than 1:6.5. No adhesive added in this procedure.
Step 4: Cooling
Coffee husk pellets discharged from coffee husk pellet maker are high in temperature and moisture content. Our counter current coffee husk pellet cooler is used to remove pellet heat as well as the moisture content to ensure pellets quality and shelf-life.
The agricultural and forestry waste pellet plant projects we have done
Step 5: Sieving
The powder materials or unshaped coffee husk pellets are sieved and send to the coffee husk pellet granulator machine again.
Step 6: Packaging
These coffee husk pellets are then packed into different capacity bags for distribution.
