Coffee shell are the residual products that are left behind after the cultivation of coffee and the wastes that are left after brewing coffee are known as coffee grounds, In addition, there is also Coffee skin, coffee residues and coffee powder.
1.Vertical feeding, directly in place.
2.The mold is stationary, the pressure wheel is rotated, the material is centrifuged, and the material is evenly surrounded.
3.The mold is double-layered, dual-use, lower cost, high production and energy saving.
4.Ring mold, vertical structure, using the granulation chamber to reduce heat.
5.The ring frequency pellet machine's independent variable frequency discharge device guarantees the pellet forming rate, reasonable design and low energy consumption.
6.The main stress components use high-alloy wear-resistant materials, and the life of wearing parts is twice that of similar products.
7.24 hours work, fully automatic lubrication.
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.
10 Top Coffee-Producing Countries In 2020
Step 1: Grinding
coffee husk is crushed with the help of hammer mills or a 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 pellet 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.
How to Make Coffee Shell Into Pellets
Step 4: Cooling
Coffee husk pellets discharged from pellet mill are high in temperature and moisture content. Our counter current pellet cooler is used to remove pellet heat as well as the moisture content to ensure pellets quality and shelf-life.
Step 5: Sieving
The powder materials or unshaped coffee husk pellets are sieved and send to the pellet mill again.
Step 6: Packaging
These pellets and briquettes are then packed into different capacity bags for distribution.
1. The product is oil-bearing and is therefore water repellent on storage and contains less dust.
2. A much better combustion value compared to wood pellets.
3. The ash of olive burning has no disposal rights and is therefore suitable for spreading over the crops or the land as fertilizer because of its purity.
4. Olive pellets and olive cake are available throughout the year with residue from production.
5. No burden on the environment by cutting down trees
6. A higher and better CO2 compensation
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.
