Thin Film Distillation and Wiped Film Evaporator. Pope Scientific Short Path/ Wiped-Film Stills (WFS) and Wiped-Film Evaporators (WFE) successfully separate. For certain wiping systems (fixed clearance) a wiped film evaporator is also called thin film evaporator. Short residence time and low evaporation temperature. The model used is a wiped film one and the heat transfer is supposed to be J.R. FerronTransport processes in thin liquid film during high-vacuum distillation.
Thin film, wiped film, short film Distillation:
Typical applications are high molecular weight organic compounds particularly from the fields of chemistry, pharmaceutical, agro and food industry. Generally different distillation processes are applied for a partial separation of product mixtures. The most important requirement for all distillation processes is the boiling point difference of the two fractions that have to be separated. With wiped film and short path distillation, a substantial decrease of boiling temperature is obtained by reducing the operating pressure.
It is a continuous process with very short residence time. In wiped film and short path evaporators, the crude material is heated up on the internal surface of a heated tube. A special rotating wiping system inside the evaporator is generating a very thin and turbulent film on the heated surface.
Out of the heated and thin film, the evaporation of the light boiling component takes place. The generated vapors are condensed on a condenser. The position of the condenser is the main difference between wiped film external condenser and short path evaporators internal condenser. In wiped film and short path evaporators, the wiping system is crucial. It has to generate a high turbulent film at a short residence time to enable a high evaporation rate with optimum separation efficiency.
Depending on application, the desired product is either the distillate or the residue fraction. For high solvent loads, an optional external condenser may be installed immediately downstream of the still. YHCHEM 6 inch continuous working wiped thin film molecular evaporator with only 2 weeks fast delivery.
The separation of effective components from the biological extracting solution. The price is two to three times that of similar domestic equipment. We will replace any failed components at no charge to the customers for parts or shipping. Glass Lined Evaporator Wfe TFE high efficient energy saving wiped film evaporator. Stainless steel 2 square meter rotary vacuum wiped thin film evaporator price. Or you can send your technician to our company to learn techniques.
The company is the national high and new technology enterprise. Stock available short path wiped film evaporator for cbd oil. Cost-effective thin layer evaporator scraped surface climbing falling wiped agitated thin film. Slap-up rotary falling wiped agitated thin film evaporator. Stainless steel scraper type wiped film evaporator. The rotary evaporator has advantages of large contact area, high evaporation efficient, easy to handle, low noise, good sealing performance.
Easy, straight-forward visual operation with digital speed and temperature display. The rotating sealing components are made of the latest materials domestic and overseas to enhance sealability, corrosion resistance and wear resistance. A wiping system spreads the feed material onto the heated internal evaporator surface just like in a wiped film evaporator. Unlike in a wiped film evaporator, in a short path evaporator the vapors are condensed on a condenser located inside the evaporator.
MD may take only few tens of seconds to finish a separation on short path distillatory when it takes hours on a normal evaporation apparatus.
