Single effect, climbing film evaporators are simple evaporators which can be used under vacuum at lower temperatures. The single effect evaporator is designed as a forced circulation evaporator. Designs are available in a wide range of capacities from 0.1 m2 heat transfer area to 10 m2. In terms of water evaporation capacity, the capacity ranges from 10 kg to 1000 kg water evaporation per hour.


Wide variation in the configuration is possible. The evaporator can be operated as natural circulation evaporator, if the viscosities involved are not very high. Positive displacement pumps like lobe or gear pumps could be provided for product recirculation when high viscosities are involved. Surface condenser or semi barometric condenser can be provided as required. Suitable condensate receivers can be provided whenever surface condensers are used. Condensers can be horizontal or vertical and with countercurrent or co current cooling arrangement. Dry or wet vacuum pump is provided depending upon the vacuum to be maintained. Dry vacuum pumps help creation of very low pressures resulting in low product temperatures, which may be required for certain heat sensitive products.


A wide range of materials of construction, including different grades of SS and MS for some components, depending on the requirement of the customer is possible. Extent of instrumentation can also vary. Simple indicating instrumentation with manual operation of the plant or fully automatic operation plants are available. Multiple effect evaporators with different feed strategies are also available.

Scraped Surface Evaporator having heating area from 0.1 to 1.0 square meter, with or without accessories like pre-heater and condenser are available. The vertical model Scraped surface evaporator is normally provided with variable speed motor drive, Teflon scraping elements, jacketed barrel, complete with frame work and necessary instrumentation.

Evaporators are fabricated out of accurately honed, seamless tubular shells and include accurately scraping elements, driven by geared motor. The whole assembly of rotor along with motor drive system can be taken out for cleaning, maintenance and repairs.

Built in vapour separators and product receivers are provided. If required separate vapour separator and product receiver can be provided for larger units.

The unit can be designed as horizontal unit if there are limitations in building height.

These evaporators can be used for demonstration/training and small capacity commercial applications. The system has proved useful in concentrating a wide range of food products including fruit juices, plant extracts and glucose solution.
The falling film version of the long tube evaporator eliminates the problems associated with hydrostatic head. Liquid is fed at the top of long tubes and allowed to fall down the walls as a film. Evaporation occurs on the surface of the highly turbulent film and not on the tube surface. This requires that temperature differences be relatively low.
With suitable preheating arrangement the evaporator can function as once through system, giving high quality concentrates. These can be used for heat sensitive fruit juices and plant extracts.
Falling film evaporators can also be designed as multiple effect evaporators employing falling film system at the final effect.

MURHOPYE ROTARY FLASH EVAPORATOR is a Buchi type evaporator. It provides an efficient means of evaporating liquids without contamination, at a faster rate under controlled temperature and vacuum. These evaporators can also be used for degassing the solutions, extraction of solids and/ or liquids, crystallization, drying of powder & granules, mixing of solids and preparation of stationary phase for chromatography. The evaporating flask containing the solution, rotates in the temperature controlled, Stainless steel water bath. The rotation of the flask eliminates bumping and foaming of the liquid while increasing the rate of evaporation.

FEATURES:

Evaporating Flask :50 ml to 2000 ml with standard joints
Receiving flask :50 ml to 2000 ml with standard joints
