In the world of specialty coffee, flavor purity begins the moment the cherry leaves the branch. Wet processing is at the heart of this flavor alchemy. As a professional provider of coffee processing equipment solutions, we deliver more than just machines—we provide an integrated precision system from washing, sorting, and fermenting to drying, ensuring every batch of coffee beans expresses its most elegant flavor potential.
Step 1: Precision Cleaning – Laying the Pure Foundation
The flavor journey starts with absolute cleanliness. Our production line begins with an efficient Impurity Removal and Grading System:
Floatation Separator: Accurately utilizes density differences to automatically separate and remove immature beans and impurities, eliminating off-flavors at the source.
Combined Washing Unit: Employs gentle spray washing combined with drum friction technology to thoroughly yet delicately remove dust, sand, and partial mucilage from the coffee cherry surface without damaging the fruit, preparing a “clean canvas” for fermentation.
Step 2: Intelligent Color Sorting – Selecting Only the Finest Cherries
Maturity is key to flavor concentration. Our High-Performance Intelligent Color Sorter uses multispectral recognition technology and AI learning algorithms to accurately identify skin color, size, and even minor defects at speeds of thousands of beans per second.
Removes unripe, overripe, and defective cherries, allowing only fully ripe, red cherries with optimal sugar content and flavor development to proceed.
Significantly enhances raw material uniformity, the essential prerequisite for achieving a balanced, clean cup profile, directly boosting your product’s performance in quality evaluations.
Step 3: Controlled Fermentation – The Flavor Transformation Laboratory
Fermentation is the core stage of flavor development. We provide a Complete Range of Intelligent Fermentation Solutions, including whole-cherry fermentation tanks and mucilage fermentation systems for pulped beans.
Precise Temperature & Humidity Control: Our PLC automated control system enables real-time monitoring and adjustment of temperature, duration, and pH levels, ensuring the fermentation process follows the ideal profile.
Uniform Fermentation Design: Unique tank circulation and agitation designs ensure every coffee bean undergoes consistent microbial action, preventing local over- or under-fermentation. This results in a layered, clean, bright acidity and complex aroma.
Step 4: Gentle Drying™ Heat Pump Drying – Preserving the Flavor Essence
Drying is the final stage of flavor definition. Our innovative Gentle Drying™ Low-Temperature Heat Pump Drying System revolutionizes traditional drying methods.
Low-Temperature Precision Drying: Gently dehydrates beans at 35-40°C, perfectly preserving hundreds of precious volatile aromatic compounds within the bean, preventing the premature “roasted” notes caused by high heat.
Efficient, Energy-Saving, and Reliable: Unaffected by weather, operates 24/7, reducing energy consumption by up to 60% compared to traditional dryers. Uniform airflow circulation ensures consistent batch drying, eliminates mold risk, and precisely controls moisture content to the target value (e.g., 11-12%).
