Built-in chaff collector

Functions of the Built-in Silver Skin Collection Box

Maintaining Equipment Cleanliness

During the roasting process, a large amount of silver skin (chaff) detaches from the coffee beans. The collection box prevents the chaff from scattering inside the machine, which could otherwise affect equipment operation or clog the ventilation system.

Improving Coffee Roasting Quality

If silver skin remains in the roasting chamber, it may carbonize under high temperatures, producing a smoky or bitter taste that affects coffee flavor. The collection box ensures timely removal of chaff, guaranteeing uniform roasting.

Easier Cleaning and Maintenance

The centralized collection of silver skin allows for convenient periodic cleaning, reducing downtime for maintenance.

Environmental Sustainability & Recycling

Some high-end roasters repurpose collected chaff for composting or other sustainable uses (e.g., as a biofuel feedstock).

Maintenance Recommendations

Clean the collection box after each roasting session to prevent chaff buildup, which could impact heat dissipation or even cause combustion.
