A Suppressed Boiling EvaporatorSBE also called as Forced Circulation Evaporator FCE has a vertical shell and tube heat exchanger as the calandria a separator and a circulation pump for circulation of slurry though the tubesUse of axial flow pumps ensures good velocity in the tubes.
Another type of evaporator used for this type of separation is a falling film evaporator where the product mix flows down through the tubes instead of upwardA forced circulation reboiler is typically a vertically mounted exchanger with the product entering the tube side of the unit through the bottom head.
Price Rs 5 Lakh Unit Get Latest Price Product BrochureForced Circulation Evaporator is recommended for the concentration of high viscosities solutionsslurries which have a tendency to crystallize or produce scalesThe circulating product is heated when it flows through the heat exchanger and then partially evaporated when the.
Aug 17 2015 Evaluation of a MVR versus TVR heated falling film finisher Posted on 17th August 2015 in Articles Dryers Falling Film Evaporators Finishers Other Steam Infusion by John Real GLM Hydro MVR vs.
Falling Film Evaporators offer distinct operating advantages to concentrate many materials such as certain food products fruit juices pharmaceuticals and similar materials which are particularly suited to evaporation in this type of equipmentOur Falling Film Evaporators are unique as they utilize a novel operating principle from other types.
Falling film evaporators Vertical shellandtube heat exchanger with integrated wraparound monobloctype or laterally arranged separator Functional principle The liquid to be concentrated is fed to the top of the heating tubes and distributed so that it flows down as a thin film on the inside of the tube walls.
Feb 19 2020 In the normal circular evaporator the velocity of liquid flow is 03 to 1ms but forced circular evaporator increases the velocity of liquid flow to 2 to 6msIt contains a circulation pump and because of this it is used for both heat exchanger and flash separation.
FilmVap evaporators and forcedcirculation evaporator provide reliability as well as savings on both energy and cleaning in certain applications that include vinasseThe liquid distributor is the most critical component in any fallingfilm evaporator.
Forced circulation evaporator can be used when dealing with solutions with high viscosity easy scaling or easy crystallizationFeatures of forced circulation evaporator 1The advantages of forced circulation evaporator large heat transfer coefficient antisaltingout antiscaling strong adaptability easy to clean.
Forced Circulation Evaporator CharacteristicsOperates with extremely low temperature differencesVelocity mechanically produced and controlledGives high rate of heat transfer rapid evaporation and high concentration without requiring high temperatures or large heating surface.
Forced circulation evaporator is commonly used for concentration of caustic and brine solutions and also in evaporation of corrosive solutionAgitated Thin Film Evaporator Agitated thin film evaporator consists of a vertical steamjacketed cylinder and the feed solution flows down as a film along the inner surface of large diameter jacket.
Forced circulation type evaporator utilizing mostly tube type heating surface fullyThese requirements have converged modern new evaporators into a design using falling film technology with 7 or 7 thermal effects and multiple 1st effect concentrator bodies 39.
h are longtube vertical evaporators that rely upon gravity flow of a thin fluid layer from the top of the tubes where the liquid is introduced to the bottom of the unit where the concentrate is collectedEvaporation takes place on the surface of the falling liquid film which.
May 01 2021 In falling film devices this process happens at the liquidvapor interfaceIt means that the device can use a lower temperature meaning less energy use and some other benefitsFor example as there is no nucleate boiling on the tube walls the solution in the evaporator will not crystalizeThese longtube devices are very energy efficient.
Oct 09 2019 A falling film evaporator can be an extremely efficient and effective type of heat exchanger.
Shachi Engineering has established itself as Indias leading forced circulation and falling film evaporator manufacturer over the last two decadesOther products designed built and installed by ShachiWe are focused on providing customized for maximum benefit to the customerTo date we have manufactured a wide range of solutions including.
Such evaporators differ from tubular evaporators mainly in the shape and form of the heating surface which consists of an assembly or assemblies of corrugated platesThese evaporators are available in four configurations risingfallingfilm fallingfilm forcedcirculation with suppressed boiling and agitated thinfilm.
The falling film evaporator with multieffects designed by RITEK has excellent reliability and gentleness in product treatmentAs the plant is working under vacuum conditions the boiling temperatures are low and the stress of the product is reduced to minimumThe use of several effects reduces the steam consumption.
The forced circulation evaporator comprises a heat exchanger a separator and a circulation pumpThe product is sent to the exchanger where it is heated and then sent to the separatorAfter evaporation the liquid portion is pumped again to be resent to the exchanger.
The function of the evaporator is to absorb the heat from the space or surrounding medium which is to be cooled by means of refrigerationThe process of heat removal from the substance to be cooled or refrigerated is done in the evaporatorThe liquid refrigerant is vaporized inside the evaporator coil or shell in order to remove heat from a.
The temperature of the weak solution rises by passing through the heat exchangerThen the solution flows into the generator for spray falling film heating evaporatorThe thermal energy required by the generator is supplied by the solar simulatorTo improve the absorption efficiency there is forced falling film absorption in the absorber.
There are two main types of longtube vertical evaporators climbingfilm and fallingfilmIn both types feed enters the evaporators through tubes is heated and part of it evaporatesIn climbing film evaporators the liquid enters from the bottom while in falling film types it enters from the top.
THOR is widely used in the tomato industry to concentrate natural tomato juice up to 1012 BrixThe product obtained can be further concentrated in a forced circulation evaporators or it can be used for the tomato puree production as topping for peeled or diced and chopped tomatoesThanks to its modular concept the THOR preconcentrator.
Three types rising film falling film and forced circulation flashRising Film Evaporator In a typical rising film evaporator the heat exchanger is mounted vertically and the evaporator liquid flows in an upward direction through the tubesWater in the evaporator liquid boils as the liquid rises in the tubes.
Types of evaporators There are several types of evaporators available in the market depending on their use we can choose from the comprehensive list mentioned below.
