1. Overview

This advanced evaporation system is designed for concentrating mannitol solutions (up to 45% concentration) with high energy efficiency. It combines Multi-Effect Evaporation (MEE), Mechanical Vapor Recompression (MVR), and Thermal Vapor Recompression (TVR) technologies to optimize steam consumption and reduce operational costs.

2. Key Specifications

Application: Mannitol solution concentration (pharmaceutical/food grade)

Evaporation Capacity: 5 tons/hour

Final Concentration: 45% (adjustable based on process needs)

Construction Material: SS316L (corrosion-resistant, suitable for high-purity applications)

Energy Efficiency: Utilizes MVR + TVR to recover latent heat, reducing energy consumption by up to 60–80% compared to traditional evaporators.

Location: Deployed in French-funded enterprises (indicating compliance with EU standards).

3. Technology Integration

Multi-Effect Evaporation (MEE)

Multiple evaporation stages (effects) reuse vapor from the previous effect as heating steam, improving thermal efficiency.

Typically 3–5 effects for mannitol, depending on energy optimization.

Mechanical Vapor Recompression (MVR)

A centrifugal compressor recycles secondary vapor, boosting its pressure/temperature for reuse as heating steam.

Advantage: Lowers steam demand by 90% compared to single-effect evaporators.

Thermal Vapor Recompression (TVR)

A steam ejector mixes live steam with secondary vapor to enhance thermal efficiency.

Synergy with MVR: TVR handles high-load phases, while MVR maintains baseline efficiency.

4. Process Flow

Feed Preheating: Mannitol solution is preheated using waste heat.

Evaporation: Sequential concentration through multiple effects.

Vapor Reuse: MVR/TVR recovers and recompresses vapor.

Condensate Recovery: Clean condensate is recycled or discharged.

Product Discharge: Concentrated mannitol (45%) is cooled and stored.

5. Material & Design Features

SS316L Construction: Ensures resistance to mannitol’s mild corrosivity and meets hygiene standards (FDA/CE compliant).

Automated Controls: PLC system for real-time monitoring of temperature, pressure, and concentration.

Anti-scaling Measures: Optional CIP (Clean-in-Place) system for fouling prevention.

6. Advantages

Energy Savings: MVR + TVR reduces operating costs significantly.

Compact Footprint: Integrated design saves space vs. traditional multi-effect systems.

High Purity: SS316L prevents contamination, critical for pharmaceutical applications.

7. Typical Applications

Pharmaceutical: Mannitol crystallization for injectables/tablets.

Food Industry: Natural sweetener production.

This system represents a high-efficiency, sustainable solution for mannitol processing, aligning with modern industrial standards for energy conservation and product quality.
