What Are the Energy Savings and Costs of a Stork 4-Effect MVR Evaporator?

Suppose you operate or plan to implement a large-scale dairy or food processing line. In that case, you may be wondering how cost-effective the Stork 4-Effect MVR Evaporator Concentrator is compared to traditional evaporation systems. Understanding operational costs and potential energy savings is essential before investing in equipment of this scale. This blog examines energy consumption, efficiency factors, long-term cost benefits, and the impact of MVR technology on total production costs.

Before evaluating investment returns, it is essential to understand how this system operates and why it differs from conventional steam-dependent evaporators.

How MVR Technology Helps Reduce Energy Use

Mechanical Vapor Recompression is the key efficiency advantage in the Stork 4-Effect MVR Evaporator Concentrator. Instead of continuously feeding fresh steam into the system, the generated vapor is compressed, heated, and reused as the primary heat source. This closed-loop operation significantly reduces the demand for external steam.

Traditional evaporators rely heavily on boilers, whereas MVR systems utilize mechanical compression in conjunction with a multi-effect process to achieve high evaporation output at a fraction of the energy requirement.

Consumption and Operational Cost Expectations

To estimate cost, reviewing energy demand is essential. In the Stork 4-Effect MVR Evaporator Concentrator, power draw includes:

●      Approximately 350 kW for the mechanical compressor

●      Around 69 kW for pumps and supporting equipment

While this appears substantial, it must be compared to the total water removal rate. This system evaporates around 23,965 kilograms of water per hour while concentrating skim milk from 8.8 percent solids to 50 percent solids. Achieving this level of concentration using conventional methods would require considerably higher steam consumption and energy spent.

Over time, the reduction in fuel and steam usage results in significantly lower operating costs.

Throughput and Performance Efficiency

Another factor affecting cost is throughput efficiency. The Stork 4-Effect MVR Evaporator Concentrator can process approximately 29,084 kilograms of skim milk per hour, resulting in roughly 5,119 kilograms per hour of concentrated product. High throughput helps shorten production time and lowers the cost per liter processed.

The falling-film design paired with vacuum assistance supports product quality and heat sensitivity management, especially important when processing nutritional or dairy products.

Long-Term Return on Investment

While the initial price may feel substantial, the Stork 4-Effect MVR Evaporator Concentrator offers long-term operational savings due to energy efficiency, reduced steam dependency, and high automation. Over multiple production cycles, reduced utility costs and consistent concentration performance support a strong ROI.

Conclusion

When evaluating operational cost and energy performance, the Stork 4-Effect MVR Evaporator Concentrator stands out as a cost-efficient choice for high-volume food and dairy concentration. Its ability to recycle energy, reduce steam demand, and process large volumes quickly makes it a substantial long-term investment for facilities focused on operational savings and sustainable performance.
