Glass Laboratory Continuous Wiped Film Evaporation Equipment
Glass wiped film evaporators are suitable for distillation, separation, concentration, stripping, dehydration and deodorization of heat-sensitive or viscous products. Glass wiper evaporators excel at thermal separation due to their jacketed glass and corrosion-resistant tube sections.
Wiped film evaporators are ideal for handling difficult, heat sensitive and sticky materials. Often equipped with rotating wipers, it accelerates the evaporation process by maintaining turbulent flow of the product film, thereby optimizing heat and mass transfer.
The glass evaporator unit is equipped with a heating/cooling circulator as well as a vacuum pump for better functionality. These evaporators were developed due to the need to purify temperature-sensitive products by evaporation.
Pressure sensitive glass evaporators can be operated at medium or low evaporation temperatures to minimize product residence time in the evaporation chamber.

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
