MVR Falling Film Evaporator

The MVR falling film evaporator combines Mechanical Vapor Recompression (MVR) technology with the falling film evaporation process and is widely applied. Henan Jiuye Chemical Equipment Co., Ltd. has rich experience and significant achievements in this field.

The MVR falling film evaporator utilizes Mechanical Vapor Recompression (MVR) technology. The essence of this technology lies in compressing the secondary steam produced by the evaporator using a compressor, which raises the temperature and pressure of the steam, restoring its ability to act as a heat source and thus achieving the recycling of heat. During the falling film process, the material is evenly distributed to the top of the heating tubes by a distributor. Under the influence of gravity and the surface tension of the liquid film, a continuous liquid film flows down along the inner wall of the heating tube. At the same time, the steam in the shell side (secondary steam pressurized by the compressor) heats the liquid film inside the tubes, promoting the rapid evaporation of the material. Throughout this process, secondary steam is continuously generated and recycled by the compressor, and the entire evaporation system requires only a small amount of fresh steam for startup and maintaining system stability, significantly reducing energy consumption.

High Efficiency and Energy Saving

Relying on MVR technology, the demand for external fresh steam has been significantly reduced, resulting in remarkable energy-saving effects. Compared to traditional multi-effect evaporators, it can save a substantial amount of energy costs, with energy saving rates significantly improved, especially when compared to three-effect and lower evaporators.

Excellent Adaptability to Heat-Sensitive Materials

The falling film design allows the material to stay in the evaporator for an extremely short time, typically only a few seconds to several tens of seconds, which greatly reduces the risk of decomposition of heat-sensitive materials at high temperatures, perfectly meeting the evaporation needs of temperature-sensitive organic substances, ensuring product quality is unaffected.

Compact Structure

The overall structure of the equipment is compact, significantly reducing the floor space compared to traditional evaporators, effectively saving factory space, particularly suitable for production sites with limited space.

Easy and Stable Operation

With a high degree of automation and a user-friendly interface, operators can easily use the system. The system operates stably, capable of running continuously for long periods, reducing downtime caused by equipment failures, and improving production efficiency.

Low Maintenance Costs

Due to the relatively simple structure of the equipment and the careful design and strict selection of key components, reliability is high, resulting in low daily maintenance workload and maintenance costs, thereby reducing the operational costs for enterprises.

The food and beverage industry

Used for juice, milk concentrate, syrup production, and sugar manufacturing, it can evaporate at low temperatures to maintain product quality.

Pharmaceutical industry

Suitable for concentrating drug intermediates, crystallization, and solvent recovery, ensuring the stability of heat-sensitive drug components and reducing costs.

Chemical industry
