Energy-Efficient Sugar Alcohol Concentration with Myande MVR Evaporators

Boost Productivity, Improve Quality, and Reduce Energy Consumption

Concentrating low-strength sugar solutions into high-strength syrups is a key step in sugar alcohol production. Traditional evaporation methods often consume excessive energy, extend processing times, and may compromise product quality.

Myande’s MVR (Mechanical Vapor Recompression) multi-stage falling film evaporators provide a revolutionary solution—optimizing energy use, shortening processing time, and delivering superior product quality across a wide range of sugar and sugar alcohol products, including sucrose, sorbitol, erythritol, glucose, and fructose.

Advanced MVR Evaporation Technology

Myande’s MVR energy-saving evaporation technology maximizes energy utilization through a near-closed-loop system. The process captures secondary vapor generated during evaporation, compresses it using high-efficiency vapor compressors, increases its enthalpy, and returns it as a heat source to the evaporator. This reduces dependency on fresh steam, improves energy efficiency, and minimizes operational costs.

For example, in the concentration of white sugar, sorbitol, and erythritol, traditional multi-effect evaporators consume large amounts of fresh steam. Long retention times in the evaporator can trigger Maillard reactions, negatively affecting product color and purity. Myande’s solution addresses these challenges with its single multi-stage falling film evaporator, where multiple evaporator stages are integrated into one shell. Sugar syrup passes through all chambers sequentially, significantly reducing retention time, preventing Maillard reactions, and ensuring high product quality. This design also enhances heat transfer efficiency while reducing energy consumption.

Proven Results and Case Studies

Myande’s MVR evaporators have demonstrated significant results in industrial applications:

• Sugar Industry Group: Steam consumption in the concentration stage was reduced by over 90%, while product quality improved, earning high customer satisfaction.

• Biotech Company (Erythritol Production): A 39 t/h continuous erythritol evaporator using multi-stage falling film technology achieved syrup concentrations above 68%, reducing fresh steam consumption by over 90% compared to traditional five-effect evaporators.

These cases highlight the technology’s ability to deliver low-energy, high-stability, and high-quality production, meeting both operational and market demands.

Comprehensive Advantages

Myande MVR evaporation solutions provide more than energy savings:

1. High Product Quality: Low-temperature, short-residence-time evaporation prevents sugar degradation, delivering superior color and purity for high-end markets.

2. Process Efficiency: Integrated design and intelligent control systems minimize manual intervention and reduce operational errors.

3. Compact & Cost-Effective: The equipment footprint is small, automation is high, and long-term labor and infrastructure costs are reduced.

4. Sustainability: Reduced steam consumption leads to lower fuel use and carbon emissions, supporting environmental responsibility.

In today’s industrial landscape, where energy efficiency, sustainability, and product quality are critical, Myande MVR energy-saving evaporation technology empowers sugar and sugar alcohol producers to achieve higher efficiency, improved product quality, and reduced environmental impact. By combining advanced process engineering, smart automation, and energy recovery, Myande helps the industry transition toward cleaner, smarter, and more competitive production.
