Our company launches an economical all-in-one sorting machine for coffee beans, integrating gravity density destoner and standard CCD optical color sorting unit. This combined model completes heavy impurity removal and defective bean separation in one single pass, eliminating the need to purchase two separate machines. Featuring stable performance, low maintenance cost and friendly entry price, the equipment targets small & medium coffee plantations, roasting factories and green coffee exporters. Mass shipments have been delivered to major coffee producing countries including Ethiopia, Indonesia, Vietnam and Brazil, solving three core production pain points: low manual sorting efficiency, roaster damage caused by stones, and high labor & processing costs.
Industry Pain Points for Global Small Coffee Processors
Most medium & small coffee manufacturers worldwide suffer from three common operational troubles:
Raw green coffee is mixed with stones, clods, metal fragments and twigs. Hard impurities directly scratch roaster drums and lead to frequent expensive maintenance. Buying separate destoner and color sorter requires extra conveyors, occupies larger workshop space and doubles overall investment.
Manual visual sorting for moldy, black, underripe and over-fermented beans brings rising labor costs year by year. Manual sorting cannot guarantee consistent quality between batches, failing basic grading standards for EU & North America coffee import.
High-end AI multi-spectrum sorters come with unaffordable price tags. For bulk commercial coffee processing, advanced intelligent functions are redundant and waste capital for startups and medium-scale factories.
To meet global market demand, our R&D team developed this integrated machine, combining front destoning and rear standard optical sorting in one cabinet, balancing sorting performance and procurement budget for commercial bulk coffee production.
Working Principle – Gravity Destoner + Standard Basic Color Sorter
The machine adopts serial integrated flow design. Coffee beans feed once and finish two processing stages with gentle conveying to minimize bean breakage rate:
Front Gravity Density Destoner Module
Based on wind vibration stratification technology, heavy contaminants like stones, metal and soil blocks are fully separated via density difference. Stone removal rate reaches above 99%, protecting roasters and grinders from abrasion. Compatible with washed, natural and honey processed green coffee beans.
Rear Standard CCD Optical Color Sorting Module ,Equipped with regular full-color CCD cameras, the system distinguishes good beans and discolored defective beans via color threshold analysis. It reliably removes moldy beans, black beans, pale immature beans, insect-damaged and fermented defective particles. Pre-set sorting programs for Arabica and Robusta are built into touch screen, requiring minimal training for operators without complicated parameter adjustment.
Core Competitive Advantages for Overseas Buyers
Integrated Design Cuts Cost & Floor Space
One machine replaces independent destoner and separate color sorter, saving over 30% workshop area, eliminating extra conveyors, frames and power distribution. Lower total power consumption reduces long-term electricity expense; combined purchase price is far lower than two individual units.
Full 304 Stainless Steel Food-Grade Construction
All bean contact parts adopt anti-rust stainless steel, adapting to humid Southeast Asia and dusty high-temperature Africa production environments. Standardized universal spare parts are easy to source locally overseas with low maintenance threshold.
Multiple Capacity Models for All Client Scales
Small models 50–300kg/h for roastery workshops & micro plantations; medium 500–1000kg/h for mid-sized factories and export traders. Equipped with movable casters, no civil foundation required for installation, ready to run after power connection.
Stable Output Meets International Export Grading
Beans processed by this machine are free of stones and obvious discolored defects, greatly reducing secondary manual re-sorting. Uniform batch appearance improves negotiation advantage for bulk coffee export.
Complete Foreign Trade Support
CE certified, customized voltage & plug types for global markets. Free raw bean test sorting video, on-site overseas installation & commissioning, 12-month full machine warranty. MOQ is 1 unit, supporting LCL single set shipment and full container bulk order.
Real Feedback from Global Overseas Clients
This combined sorter has been widely supplied to Vietnamese roasteries, Indonesian coffee plantations and Ethiopian green coffee exporters. Client feedback highlights: the machine replaces 6–10 manual sorters, recovering equipment investment within 3–8 months. The front destoner completely avoids roaster abrasion maintenance, while standard optical sorting fully satisfies daily bulk coffee processing without unnecessary premium high-cost intelligent functions, delivering superior cost performance compared with split equipment on the market.
Closing Call to Action
We keep developing full sets of coffee cleaning & sorting production lines customized according to client output and workshop dimensions. Global coffee buyers may contact us via website message, WhatsApp or email to obtain full technical datasheets, sorting demo videos and FOB quotation. Remote factory test sorting observation is available upon reservation.
