Energy and water saving
MVR evaporators save more than 80% of energy, save more than 90% of condensate, and reduce floor space by more than 50% compared to traditional evaporators.
High steam utilization
Secondary steam is fully utilized, and the economy of live steam is equivalent to 30 effects of multi-effect evaporation, reducing the need for external heating and cooling resources, reducing energy consumption and reducing pollution.
Gentle evaporation
Due to the use of compressor to provide heat source, the temperature difference is much smaller than that of traditional evaporators, which can achieve gentle evaporation, greatly improve product quality and reduce fouling.
Simple and reliable
No need for a condenser or only a small area of condenser, the structure and process are very simple, fully automatic, continuous operation, safe and reliable.
Low denaturation of heating
The evaporator is the material evaporated at low temperature (evaporation temperature 40 °C-100 °C), the material liquid is uniform, the material does not run away, it is not easy to coke, and the material is heated and denatured with minimal progress.
Scraper heater structure
The structure of the scraper heater has a high heat transfer coefficient value, large evaporation capacity, and the evaporation intensity can reach 200kg/m2·hr, and the thermal efficiency is high.
Shorter heating time of materials
The heating time of the material is short, about 5-10 seconds, and it works under vacuum conditions, which is more beneficial to heat-sensitive materials, keeping various components without any decomposition and ensuring product quality.
Wide Range of Viscosity Adaptability
It can adapt to a wide range of viscosity changes, both high and low viscosity can be processed, and the viscosity of materials can be as high as 100,000 centipoise (CP).
Lower vacuum resistance
Due to its unique evaporation form, the treated material only forms a film on the evaporation surface and does not accumulate on the evaporation surface, therefore, there is no problem of the liquid column static pressure in other evaporation forms to offset the vacuum degree (the vacuum degree in other evaporation forms only reflects the vacuum degree on the surface of the liquid phase body in the system), and the vacuum degree displayed by the system is the vacuum degree of material evaporation.
High evaporation intensity
The improvement of vacuum degree reduces the boiling point of the treated material, increases the driving force of the temperature difference between cold and hot medium, the forced action of the scraper makes the liquid film turbulent and becomes thinner, the self-cleaning effect of the scraper inhibits the formation of the scale layer on the heating surface, increases the heat transfer coefficient, and improves the evaporation intensity.
Short heating time
Since the scraper evaporator is a special falling film evaporator, the residence time of the material on the heating surface is very short, about 10-60 seconds (depending on the specification), which is especially suitable for handling heat-sensitive materials.
Good flexibility
The amount of material entering the evaporator per unit time determines the thickness of the liquid film formed on the heating surface, because the liquid film of the scraper evaporator is formed by the scraper, so the feed amount can be adjusted in a wide range.
