    Description

    MVR Evaporation plant delivers substantial operational cost savings in areas with an ample supply of low-cost electrical energy.

    Once an MVR evaporation plant is running, little or no additional steam is required. In the MVR evaporation plant, a centrifugal fan is used to recompress the vapour to a higher pressure, resulting in a temperature rise. This means that the recompressed vapour can be used as the evaporation plant heating medium, while the condensate is ideal for preheating of the feed product.

    For low boiling point increases, a single-stage compressor can be used to fulfill the requirements of the design.

    For high boiling point increases, we will provide two designs: multiple-stage compressors, single stage compressors combined with multiple-effect.

    The MVR evaporation plant almost doesn't use steam, but electric energy is required as the main energy source.

    The power consumption of the main motor of MVR is due to the heat exchange area and the evaporating temperature of the evaporation plant. The Heat exchange area is bigger, and as a result, power consumption is lower, but the investment in equipment is increased.

    Evaporating temperature is higher and as a result, power consumption is lower, but fouling in the calandria is therefore increased; Evaporating temperature is lower and as a result, power consumption is higher.

    MVR can be powered by an electric motor, the rotary speed of an MVR can be controlled by a frequency converter, and the rotary speed of an MVR may control the evaporation rate and final concentration of the MVR evaporation plant.

    Frequently Asked Questions
    Q
    What is an MVR Evaporation Plant and how does it work?
    An MVR (Mechanical Vapour Recompression) Evaporation Plant uses a centrifugal fan to recompress the vapour generated during evaporation to a higher pressure, which raises its temperature. This recompressed vapour is then recycled as the heating medium for the evaporation process, dramatically reducing the need for external steam. The result is a highly energy-efficient system powered primarily by electricity.
    Q
    How much energy can an MVR Evaporation Plant save compared to a traditional multiple-effect evaporation plant?
    The savings can be substantial. For example, with an evaporation rate of 50T/h and running 8,000 hours per year, a 4-effect evaporation plant may cost 14,080,000 RMB annually in energy, while an MVR plant costs only 6,400,000 RMB — saving approximately 7,680,000 RMB per year. The exact savings depend on local electricity and steam pricing.
    Q
    What industries are MVR Evaporation Plants best suited for?
    MVR Evaporation Plants are particularly well-suited for the food and beverage industry (e.g., evaporation of milk, whey, and sugar solutions), the chemical industry (evaporation of aqueous solutions), the salt works industry (evaporation of saline solutions), and environmental protection applications such as concentration of wastewater.
    Q
    What factors affect the power consumption of an MVR Evaporation Plant?
    Two main factors influence power consumption: (1) Heat exchange area — a larger heat exchange area results in lower power consumption but increases equipment investment cost. (2) Evaporating temperature — a higher evaporating temperature lowers power consumption but increases the risk of fouling in the calandria, while a lower evaporating temperature increases power consumption.
    Q
    Can the evaporation rate of an MVR plant be controlled?
    Yes. The MVR can be driven by an electric motor, and its rotary speed can be precisely controlled using a frequency converter. By adjusting the rotary speed of the MVR, operators can effectively control both the evaporation rate and the final concentration of the product in the evaporation plant.
    Q
    What information is needed to select the right type of evaporation plant?
    Selecting the right evaporation plant requires detailed information across several categories: capacity and operation data (product name, feeding and final concentration, evaporation rate), product properties (viscosity, foaming tendency, boiling point, fouling behavior), utility requirements (steam pressure, cooling water temperature, voltage/frequency, energy prices), waste heat parameters, material selection requirements, and the preferred energy efficiency technology (MVR, TVR, multiple-effect, or waste heat evaporation).
