Coffee skin coffee residues coffee husk coffee waste ground coffee powder pellet line

Coffee ground has low-carbon and environmental combustion material,the oil extracted from spent coffee grounds can be further processed into bio-diesel,and their leftovers can be pelletized into solid biomass fuel which possesses higher heat value over those made from wood and agricultural wastes.

Different from the whole procedure of crushing,drying,pelletizing,cooling and packing for other material,coffee grounds pelletizing is much easier and far more convenient to be completed in virtue of their own features and properties.

Coffee skin coffee husk coffee waste ground information:

1. moisture:

for most other raw materials,a drum dryer is needed because biomass pellet machine has a strict requirement for their waste content,about 10~15%.

2. carbon content:

generally more carbon content equals to better combustion feature and higher heat value,the coffee ground takes the top place among various kinds of material because of its 52.2% content.

3. ash content:

different from other biomass wood waste or agricultural waste,the coffee ground has less ash content,because it is obtained in the making process of food which has been well cleaned and inspected.

4. lignin content:

lignin plays the role of additive during coffee grounds pelletizing,whithout such substance,the final biomass pellet may not be hard enough and break easily.

5. heat value:

the heat value of waste coffee grounds is more than 4200MJ/kg,this makes coffee pellet more ideal biomass fuel.

Coffee ground pellet production:
1. pelletizing process
the dried coffee waste ground are fed into pellet machine chamber and sent into the space between rollers and die under the rotating strength of rollers,with enough pressing force of die and rollers on materials and friction between die and materials as well as materials and rollers,they are squeezed out as coffee ground pellet.

2. cooling process
the counter flow type pellet cooler is adopted for the high temperature coffee pellets.Its working principle is the opposite direction of material and air feeding,the pellets from top to bottom while the wind coming from bottom to top,which can prevent coffee pellet's surface cracking and ensure their cooling effect.

3. packing process:
after being pelletized and cooled,the coffee pellets will be packed in order to make sure subsequent storage and convenient delivery.
We have two packing ways,one in ton bag packing machine in 600~1200kg/bag,the other is small bags packing like from 15~50kg/bag as per customers' requirements.

Advantages of coffee pellets
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 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.

Why coffee pellet production is becoming popular:

1. the problem of energy shortage is more and more vigorous,so development and production of biomass pellet fule has become a way out.
2. And,it will bring decontamination burden for environment if just throwing away of waste coffee grounds.
3. Besides,the coffee ground used as fertilizer are harmful for soil due to the caffeine,tannis and polyphenols.

We have been successfully made coffee pellets from different type coffee waste with video and pics,if you are interested in this pellet line,please contact us freely for more information.
