Key Technical Sections & Specifications:

1. Green Coffee Handling & Roasting

• Cleaning Section: Includes bucket hoisters, pneumatic conveying (400kg/h), magnetic separation, and storage silos (11m³) to prepare green beans.
• Roasting Section: Equipped with a gas combustion roaster (200-320kg/h capacity) featuring a cooling device, destoner, and chaff collector.
• Bean Preparation: Includes a bean breaking section with a granulator (300kg/h) and pre-wetting devices to optimize extraction efficiency.

2. Extraction & Water Treatment

• Water System: Comprehensive treatment unit including Reverse Osmosis (RO) and Ion Exchange (5m³/h) with high-pressure feeding pumps (20bar).
• Extraction Battery: Seven (7) COL-350 extraction tanks with high-pressure capabilities, equipped with heat exchangers and continuous filters. This section utilizes a multi-stage process to maximize soluble solid recovery.
• Clarification: Features two disc separators (1500L/h) to remove insoluble solids and clarify the extract prior to concentration.

3. Concentration & Aroma Recovery

• Evaporation: A 3-effect Falling Film Evaporator (Evp-2.5-3000) capable of evaporating $3500kg/h$ of water. Includes thermal compression pumps and condensers to concentrate the coffee extract efficiently.
• Aroma Recovery Unit (ARO-200): A specialized system designed to capture and preserve volatile coffee aromatics. It includes a flash separator, rectifying column, and condenser array to reintegrate premium aroma into the concentrate.

4. Spray Drying System

• Drying Tower: Industrial spray drying tower featuring high-pressure nozzle atomization, steam heat exchangers, and a vibration fluid bed for secondary drying/cooling.
• Air Handling: Includes dehumidifiers, blast fans, and extensive filtration (60-mesh inlet filters) to ensure sanitary drying air conditions.
• Product Collection: Equipped with cyclones, rotary valves, and a fines return system to minimize product loss.

5. Automation & Control Architecture

• PLC System: Centralized control utilizing Siemens S7-300 and S7-200 PLCs for reliable logic processing.
• HMI/SCADA: Industrial PC (IPC) integration for real-time monitoring and data logging.
• Instrumentation: High-precision sensors including Endress+Hauser (E+H) vortex flowmeters, pressure transmitters, and temperature sensors.
• Drives: Variable Frequency Drives (Inverters) provided by Schneider/Telemecanique for energy-efficient motor control.

Additional Information
