• MVR thin film evaporator

• Product advantages：

1. MVR evaporators save over 80% of energy, over 90% of condensate water, and reduce footprint by over 50% compared to traditional evaporators.
2. The secondary steam is fully utilized, and the economy of steam production is equivalent to 30 effects of multi effect evaporation, reducing the demand for external heating and cooling resources, lowering energy consumption, and reducing pollution.
3. Due to the use of a compressor as the heat source, the temperature difference is much smaller compared to traditional evaporators, which can achieve mild evaporation, greatly improve product quality, and reduce scaling.
4. No need for a condenser or only a small area of condenser is required. The structure and process are very simple, fully automatic operation, continuous operation, and safe and reliable.
5. The evaporator is used to evaporate materials at low temperatures (evaporation temperature of 40 ℃ -100 ℃), with uniform material distribution, no material leakage, low coking, and minimal material deformation during heating.
6. The scraper heater structure has a high heat transfer coefficient value, a large evaporation capacity, an evaporation intensity of up to 200kg/m2 · hr, and high thermal efficiency.
7. The heating time of the material is short, between about 5 seconds and 10 seconds, and it works under vacuum conditions, which is more advantageous for thermosensitive materials, keeping various components from decomposing and ensuring product quality.
8. It can adapt to a wide range of viscosity changes and handle both high and low viscosity materials. The material viscosity can reach up to 100000 centipoise (CP)
9. The equipment has a small footprint, simple structure, easy maintenance, and easy cleaning.
10. Reduced vacuum resistance: Due to its unique evaporation form, the processed material only forms a film on the evaporation surface and does not accumulate on the evaporation surface. Therefore, there is no problem of liquid column static pressure offsetting the vacuum degree in other evaporation forms (in other evaporation forms, the vacuum degree only reflects the vacuum degree on the surface of the liquid phase in the system). The vacuum degree displayed by the system is the vacuum degree of material evaporation.
11. High evaporation intensity: The increase in vacuum degree reduces the boiling point of the processed material, increases the temperature difference driving force of the cold and hot media, and the forced action of the scraper makes the liquid film turbulent and thinner. The self-cleaning effect of the scraper suppresses the formation of scale layers on the heating surface, increases the heat transfer coefficient, and improves the evaporation intensity.
12. Short heating time: Due to the fact that the scraper evaporator is a special type of falling film evaporator, the residence time of the material on the heating surface is very short, about 10-60 seconds (depending on the specifications), making it particularly suitable for handling heat sensitive materials.
13. High operational flexibility: The amount of material entering the evaporator per unit time determines the thickness of the liquid film formed on the heating surface. As the liquid film in the scraper evaporator is forcibly formed by the scraper, the feeding amount can be adjusted within a large range.
