What is a Wipe Film Evaporator?

A Wipe Film Evaporator is a type of thin-film evaporator that employs a rotating wiper to spread the feed liquid as a thin film over the heated surface. The film is then evaporated and condensed as it moves through the evaporator in a spiral path, thanks to the centrifugal force generated by the rotating wiper blades.

This design allows for highly efficient heat transfer, rapid evaporation, and excellent separation of the components. The Wipe Film Evaporator can handle a wide range of feed materials, including highly viscous, heat-sensitive, and foamy liquids. It is also suitable for use with solutions containing solids, crystals, or suspensions.

Features and Benefits of Wipe Film Evaporator

Our Wipe Film Evaporator boasts several key features and benefits that set it apart from other types of evaporators available in the market. These include:

1. High Efficiency

The Wipe Film Evaporator offers high rates of liquid evaporation, resulting in higher product yields, reduced processing time, and lower operating costs. It achieves this by maximizing the surface area of contact between the feed and the heated surface, thanks to the low liquid depths and the wiper's continuous contact.

2. Superior Heat Transfer

With its spiral flow path, the Wipe Film Evaporator enables excellent control of the heating temperature and distribution, resulting in minimal heating imbalances or hotspots. Moreover, the rotating wiper blades help to scrape and mix the feed, further enhancing the heat transfer and minimizing fouling or scaling.

3. Versatility

Our Wipe Film Evaporator is highly versatile and can be used for different applications, including concentration, distillation, stripping, evaporation, and crystallization. It is suitable for various feed materials, including chemicals, pharmaceuticals, food and beverage, petrochemicals, and many more.

4. Low Maintenance

The Wipe Film Evaporator has a minimal number of moving parts, making it easy to maintain and service. Moreover, it has self-cleaning properties, thanks to its rotating wiper blades, which help to remove any fouling or scaling and ensure consistent performance over time.

5. Eco-Friendly

The Wipe Film Evaporator is designed to minimize waste and environmental impact. It requires less energy to operate than most conventional evaporators, reducing the carbon footprint and energy costs. Additionally, its gentle evaporation process preserves the feed's quality and reduces product degradation, minimizing the need for additional chemicals or processing steps.

Applications of Wipe Film Evaporator

Our Wipe Film Evaporator is suitable for different applications, such as:

- Concentration of heat-sensitive and viscous liquids, such as syrups, juices, amino acids, and antibiotics.

Introduction

Scraper evaporator, which is a highly adaptable new type of evaporator, for example for high viscosity, heat sensitive and easy to crystallize and scale materials. It is mainly composed of a heating jacket and a scraper. The jacket is heated by steam. The scraper is mounted on a rotatable shaft. The scraper and the inner wall of the heating jacket are kept at a small gap, usually 0.5 to 1.5 mm. After the preheating, the liquid is added from the upper part of the evaporator in the tangential direction. Under the action of gravity and rotating scraper, the lower rotating film is distributed on the inner wall, and is continuously evaporated and concentrated during the descending process, and the finished liquid is discharged from the bottom. The secondary steam escapes from the top. In some cases, this evaporator evaporates the solution to give a solid product directly at the bottom.

Scraper evaporator use characteristics

1. The scraper evaporator has high efficiency and high capacity.

2. The material of the scraper evaporator is short on the evaporation surface, about ±10 seconds, no coking, no scaling.

3. The squeegee evaporator enables low temperature evaporation under vacuum conditions.

4. The scraper evaporator is suitable for continuous production, with large operation flexibility, simple structure, easy maintenance, and self-control.

5. The squeegee evaporator changes the inclination angle of the groove outside the squeegee, and the time during which the material stays in the evaporator can be adjusted to meet the needs of evaporation of different viscosity materials.

6. The scraper evaporator uses stainless steel for all parts and equipment that contact the liquid to keep the liquid from contamination.

7. The top of the squeegee evaporator is equipped with a quick opening cover for easy brushing of the heating tube. Light holes and mirrors are installed on both sides of the top for easy observation during operation.

Scraper evaporator application range

Scraper evaporator is widely used in petroleum, chemical, pharmaceutical and other industries, especially for high viscosity (such as silicone, honey, etc.) and materials that are easy to crystallize, scale, and heat sensitive.
