Making Coffee Ground & Coffee Shell into Biofuel Pellets

In May 2018, the Indonesian customer sent his raw material for testing. The raw material is the coffee ground and coffee shell. They have many raw materials like coffee husk etc. wanting to purchase a fuel pellet production line for selling.

The raw material sent by the Indonesian customer:
coffee ground coffee shell
(coffee ground and coffee shell)
The one with light color is the coffee shell, which is taken from the processing procedure. It is the inner shell inside of the outer shell, instead of the outer brown shell.

The following picture is the testing result:

The pictures are the pure coffee shell pellets, pure coffee ground pellets, mixed pellets of coffee husk and coffee residue. The pure coffee pellet has the deepest color, while the pure coffee shell pellets have the lightest color. From the changing of the colors, we can see the ratio of the two kinds of ingredients, the deeper the color, the more portion of the coffee residues.

After receiving the raw material from the Indonesian customer, GEMCO factory workers tested the coffee shell on different data with a good result. Both of the two kinds of raw material can be made into good quality pellets. After the actual detecting and testing, the two kinds of raw material can be made into best quality pellet respectively. Mixing together results the poor quality. So, the technician suggested that the two raw material be made respectively instead of mixing them together.

Flat Die Coffee Ground Pellet Mill

ZLSP200B coffee ground pellet millThe coffee ground pellet mill or coffee shell pellet mill for this testing is respectively the ZLSP300B R-type and ZLSP200B type flat die pellet mill. ZLSP200B type coffee ground pellet mill is used for making coffee ground pellets, and ZLSP300B R-type coffee shell pellet mill is for making coffee shell pellets. Both of flat die and ring die pellet mills can be used for making coffee residue and shell pellet. The production capacity of the single flat die pellet mill ranges in 50-800 kg/h. If you have less requirement for the production capacity, flat die pellet mill is suggested. Because the flat die pellet mill is always used for small scale pellet production.


Ring Die Coffee Ground Pellet Mill

Due the high requirement in production capacity, we adopted the ring die pellet mill as the key equipment, which is usually used in the larger production line.
Making coffee ground &coffee shell into bio-fuel pellets has been the popular industry currently. The coffee ground and coffee shell sent by the Indonesian customer is only one of the various residue materials. Materials like crop husk, wood residue of the furniture factory and wood chips are the quality raw materials for making fuel pellets.
