90 – 95 Removal efficiency Dependent upon input material andor SOP50176c – 85176c Operational evaporator temperatureWith its unique design the FFESeries Falling Film Evaporator greatly increases the throughput of botanical oil production boasting an impressive 4560 gallons per hour of alcohol recovery.
Falling film evaporation on the horizontal tube is a new technology for seawater desalinationBecause the phase changes occur on both sides of film evaporation and the film flow of the liquid outside the tube contributes to speed up the separation of vapor and liquid its heat transfer coefficient is high.
Falling Film Evaporator Operation.
Falling film type plate evaporator each group is composed of two plates in different formsThe material enters from the left and right openings of the upper end of the plate and the soda mixture goes out from the middle of the lower end2 Have deep experience in the design of plate heat exchanger.
Falling film evaporators allows following advantages when compared to conventional rising film evaporatorsOperates at low exhaust pressure and temperatureOperates at smaller delta t and higher vapour temp which results in steam savingShort retention time minimizing inversion losses and colour formationHigher heat transfer coefficient.
Falling film evaporators are used extensively in chemical process industry food and paper industryDue to the absence of static static head effect caused by liquid column as in other types of evaporators evaporation can take place at very small effective mean temperature differencesThe temperature diffference are tipically between 3 8C.
Falling film evaporators are widely used in the evaporation and concentration of water or organic solvent solutions of falling film evaporator manufacturers in the pharmaceutical food chemical light industry and other industries and can be widely used in the treatment of waste liquids in the above industriesIt is especially suitable for heatsensitive materials.
Wasteheat fallingfilm evaporator uses waste heat from a dryer as a heat source often reusing steam in multiple stages forSo that the material can be circulated back to the dryer for effective recovery.
Jun 05 2019nbsp018332A falling film evaporator should be used for materials with relatively high concentration and viscosityIt is suitable for materials with small evaporation capacityWhat are the Advantages of a Falling Film Evaporator A falling film evaporator can be widely used in industrial chemical biochemical and other fields.
LH Falling Film Evaporator Working PrincipleThe material is added from the top of the evaporator and flows along the tube wall under the action of gravityDuring the process the solvent is continuously evaporated so that the solute concentration is increasedThe finishing liquid is obtained at the bottom of the heat exchanger.
Mar 18 2022nbsp018332Falling film type plate evaporator each group is composed of two plates in different formsThe material enters from the left and right openings of the upper end of the plate and the soda mixture goes out from the middle of the lower end.
May 01 2021nbsp018332In 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.
Nov 07 2018nbsp018332Now falling film heat transfer coefficient for evaporation can be calculated by applying EqsThe material resistance is neglected due to very thin tube wall less than 05 presents the calculation process for falling film heat transfer coefficient.
Structure of falling film evaporator The main body of the equipment is composed of Ⅰ Ⅱ Ⅲ effect heaters separators heat pumps condensers sterilizers insulation pipes material pumps water pumps and instrument cabinetsThis equipment is made of stainless steel in contact with materialsThe scope of application of falling film.
The advantages of falling film evaporators are that it is a relatively low cost low product hold up small space requirement good heat transferThe common disadvantages of falling film evaporators are it requires high headroom not good for salting and scaling materials recirculation is required.
The Falling Film Evaporator FFE has its own take on the technology incorporating improved features that keep the operator in mindAs a large portion of the tincture processed using a falling film evaporator is coming from a cold ethanol extraction the design takes advantage of the cooling power that is already a sunken cost in the form of the electricity used to generate it.
The Falling Film Evaporator with capacity ranges of up to 150th and relatively small floor space requirement is the most widely used evaporator in the process industryParticularly well suited for temperaturesensitive products liquids containing small quantities of solids and with a low to moderate tendency to form incrustations.
