What Processes Coffee Bean Peeling Will Be

A coffee bean husking machine undergoes several processes to remove the outer husk (such as parchment or silver skin) from the beans. The key steps involved are:
Feeding:
Coffee beans are loaded into the machine through the feeding hopper for processing.
Husking (Peeling):
Mechanical Friction: The machine uses rollers, grinding plates, or rubber drums to create friction, which removes the outer husk.

Impact Husking: High-speed rotating hammers or impact mechanisms crack and separate the husk from the beans.
Separation:
Airflow Separation: A fan or air-blowing system removes the lighter husks, while the heavier coffee beans continue to the next stage.
Sieving Separation: A vibrating or rotating sieve sorts and separates the husked beans from the remaining husks.
Collection & Discharge:
Husk Collection: The removed husks are collected in a dust bag or container to prevent environmental pollution.
Bean Discharge: The cleaned coffee beans are discharged through an outlet, ready for further processing like sorting, grading, or roasting.
Dust Removal & Cleaning:
Dust Extraction System: Some machines feature dust removal systems to minimize airborne particles and maintain a clean working environment.
Machine Cleaning: Regular cleaning of the husking chamber and air ducts ensures optimal performance and prevents husk buildup.
