Wet grinding system for coffee flavor preservation
Achieve unparalleled coffee flavor and aroma by integrating a low-temperature wet grinding technique that maximizes yield and enhances taste, setting your instant and freeze-dried coffee products apart in the competitive market.
Processes Coffee for Optimal Flavor Preservation
The GEA MicroWet Grinding System is a specialized solution for coffee producers seeking to maintain coffee essence while increasing production efficiency. This system uniquely employs a low-temperature wet grinding process that integrates into coffee extract lines, ensuring optimal flavor and aroma retention. Starting with pre-ground coffee, it mixes with coffee extract, cooling before undergoing double grinding via corundum stone mills to produce fine particles around 20 μm. This method enables coffee solutions for spray or freeze drying, enhancing mouthfeel and flavor while utilizing 100% of the coffee bean’s potential. Operationally, the system handles up to 3,000 kg/h of extract with adjustable roast coffee dosing up to 100 kg/h, making it a versatile choice for both spray-dried and freeze-dried coffee products.
Its continuous, low-temperature processing is designed to fit seamlessly into existing coffee production setups or work independently, offering increased dryer capacity and product quality improvements. Constructed with industrial compatibility in mind, it ensures efficiency and reliability, minimizing energy waste and maintaining operational standards for food safety. The system supports customizable integration with existing processes, providing the scalability and engineering support necessary for modern coffee production facilities.
