How to Sort Coffee Beans?


Sorting coffee beans is a simple process, SG Sorting Equipment only includes two main processes:

Color Sorter Working Principle

Graphic: Coffee Beans Sorting Process

  1. Identification Process

Every original coffee bean will be imaged when it passes through the sorting room. Built-in CCD Sensors will read the color, size and shape information in the photos.

By comparing this optical information with regular coffee beans’, SG identification equipment will mark each target coffee bean a bad tag or good tag.

All these tags are actually electric signals and will be transferred to Rejection system.


  1. Rejection Process


Rejection Process is one of the most important parts of the coffee beans sorting process. After receiving the signals, the Rejection System will start the rejection process.

When receiving a bad signal, the ejector will open its spout and release the powerful air to change target coffee bean’s movement track.


Main Accessories:


Vibrator: Coffee Beans Sorting Process starts here. Unique Structure design allows the coffee beans to slide down into the chute in a single layer.


Chute: A smooth chute can make sure all coffee beans get the same speed when they leave off the chute. Coffee Beans slide down at a uniform speed, which helps to track and lock each coffee bean’s location.

Light Source: Stable LED light Source to provide constant brightness for the picture acquisition process, which is the benefit for images reading.

Camera: The high-pixel camera captures more details of coffee bean color differences. SG Sorting machine installs two sets of high-pixel cameras from both sides.

Ejector: SG adopts 12000+Hz High-frequency electromagnetic ejectors, which helps face the fast coffee beans and change their movement route.

CPU Board: As the brain of the entire coffee bean sorting process, the CPU Board rigorously calculates and issues commands that are culled or retained, driving the entire sorting process.
