High Oil Coffee Bean Roller Miller
Introduction
The High Oil Coffee Bean Roller Mill is specially designed for grinding oily and sticky materials such as coffee beans.
It effectively overcomes common issues like clogging, sticking, and overheating that occur in conventional grinding equipment.
Using a unique roller extrusion and shearing mechanism, the machine ensures smooth operation, uniform particle size, and stable performance even when processing high oil content materials.
Material Characteristic
This is the powder produced by grinding two types of coffee beans using a High Oil Coffee Bean Roller Miller. We tested the machine with two types of coffee beans - one with high oil content and the other with slightly lower oil content. It can be seen that the coffee beans with higher oil content produce finer powder with a darker color. The fineness of the ground coffee powder is approximately 30 mesh. We can also control the grinding fineness by adjusting the gap between the rollers.
FAQ
1. What fineness can be achieved?
A: The final particle size can typically reach 20–40 mesh, depending on the material condition and machine adjustment.
In this test, the coffee beans were ground to approximately 30 mesh.
2. Q: Will oily materials cause blockage during grinding?
A: Oily materials may cause clogging in conventional machines.
However, the roller mill uses a shearing and extrusion mechanism, which minimizes heat generation and reduces sticking issues.
3. Q: Is temperature increase a concern during grinding?
A: No significant temperature rise occurs during the process.
The low-speed rolling design helps protect the material properties, making it suitable for heat-sensitive materials.
