Pilot-scale Thin Film Evaporation

Laboratory Thin Film Evaporation

Product Description

In the thin film evaporator, the material is evenly distributed into a thin film by the scraper or rotor on the inner wall of the evaporator. Due to the high heat transfer efficiency of the liquid film, the light components are evaporated in a very short time, and the light components after vaporization are evaporated. The components are condensed and liquefied in an external condenser, thereby realizing the separation of the two components. The wiped film evaporator is mainly used for the separation of heat-sensitive and high-boiling products.

Product Introduction

The aishengke series of agitated thin film evaporators have proven their efficiency as equipment for distillation and evaporation processes, where a scraper system is used for forced liquid film formation processes. It can successfully carry out multiple unit operations simultaneously, such as defoaming reaction, deodorization, cooling, heating and so on. Also, you can use it in the recovery process of organic solvents found in industrial waste. Agitated thin film evaporators are commonly used in food industry, pharmaceutical industry, light industry, environmental protection industry, petrochemical industry, etc.

How does a glass wiped film evaporator work?

In glass scraper (or thin film) evaporators, a rotating scraper system distributes the coarse product onto a thin film on the inner surface of the heating tube. The wiping system then accelerates the evaporation process by maintaining a turbulent flow of the product film to ensure optimal mass and heat transfer.

Low boiling point evaporation of the raw material in the evaporator; quickly ensures a very short residence time in the product wall. The vapor is then condensed on an external condenser and the concentrate is continuously drained from the bottom of the evaporator.

The wiping system guarantees uniform laminar mixing of the film over the entire evaporator surface. Dead space can be eliminated by wiping the unheated area and overlapping the rollers. At the same time, the liquid film on the drum is constantly renewed.

The glass thin film evaporator system completely avoids the build-up or clumping of material on the evaporator surfaces and drums that can occur with other wiping systems. The high wiping frequency and resulting boundary layer renewal rate ensures high evaporation rates.

Centrifugal force drives the wipers against the evaporator wall. Heated with hot oil or steam, the viscosity of the liquid will determine the rotational speed of the drive.

The device operates intermittently, and the feeding volume is generally designed at 0.1~3L/h. Please refer to the equipment specification table for purchase.

The characteristics of glass wiped film evaporator

Due to the nature of the materials that make up the glass wiper evaporator, all contact parts are made of glass and PTFE to ensure minimal corrosion and degradation. Since they are designed for high vacuum distillation, these evaporators must be equipped with efficient condensers.

Any good glass wiped film evaporator should have all fire rated electrical and instrumentation. It is a device that should work at the lowest possible temperature to ensure little dwell time. A key feature that differentiates a glass evaporator from other types is that it allows visual inspection.

The use of mechanical or magnetic seals is an additional measure to eliminate any risk of leakage. The modular system of all glass components allows flexible design and quick assembly of the evaporator unit. Most wiped film evaporators offer digital control of motor speed. Others have more advanced levels of automation.

In addition, suitable glass thin-film evaporators have a smooth evaporation surface, are easy to clean, and come with reliable, long-lasting drives

1.The scraper system pushes the liquid from a thin film through the rotation process, and hence it provides the appropriate evaporation efficiency and also reduces its operating time.

2.The high-precision pipe made from glass allows the liquid to create a unified thin film over the hot surface.

3.The Scraper system is built of SUS 316L and PTFE; all the other parts that come in contact with the liquid or gas are usually created from high borosilicate glass 3.3 and PTFE, as both the elements have an excellent corrosion resistance properties.

4.The principle evaporation compartment is built from high borosilicate glass 3.3, which allows you to observe the process closely and clearly.

5.You can control the temperature and keep it to the absolute level. The Agitated Thin Film Evaporator can reach up to 260°c temperature.

6.We can make the most significant size up to DN300, which can help you reach an effective evaporation area of 0.6 meters Sq.

7.A Self-cleaning roller Model, as well as the Scraper Model film-forming systems, are available with us.

8.We also have Stainless steel material used in manufacturing the distillation barrels.
