Multi-Effect Falling Film Technology Solves the Maillard Reaction Challenge in Sugar Concentration

Why Does the Maillard Reaction Occur in Sugar Concentration?

In sugar alcohol production, concentrating low-concentration sugar solutions is a critical step for improving efficiency and product quality. However, a persistent challenge exists: the Maillard reaction.

This non-enzymatic browning reaction is triggered when sugar solutions are exposed to high temperatures for extended periods, leading to:

🔸Darkened color 

🔸Nutrient degradation 

🔸Reduced product grade 

🔸Significant annual financial losses across the industry 

Traditional evaporation systems often prolong liquid residence time, unintentionally creating the perfect conditions for this reaction.

How Myande Solves the Problem

Myande addresses this issue with its multi-pass falling film evaporation system integrated with MVR (Mechanical Vapor Recompression) technology.

Key Innovation: Multi-Pass Falling Film Design

Instead of repeated circulation through high-temperature zones, Myande’s system:

🔸Uses an N-pass integrated design 

🔸Enables one-way flow through multiple evaporation stages 

🔸Forms a uniform thin liquid film under gravity 

🔸Achieves instant evaporation and separation under vacuum 

What This Means in Practice

🔸Significantly reduced residence time 

🔸Minimized risk of Maillard reaction and caramelization 

🔸Improved final product quality 

🔸Higher thermal efficiency 

Customer Success Story

A sugar plant retrofit project demonstrated:

🔸Processing capacity: 150 tons/hour 

🔸Final concentration: 72% 

🔸Steam consumption: as low as 0.1 tons/hour 

🔸Annual cost savings: over RMB 40 million (~USD 5.5M) 

Additional benefits include:

🔸One-click startup and shutdown 

🔸Automated cleaning (CIP) 

🔸Compact system layout reducing footprint and CAPEX
