Due to the intimate contact of the liquid with the heating surface, these evaporators are sensitive to fouling from precipitating solids; liquor velocity, typically low at liquor inlet (see above) is usually not sufficient to perform an effective self-cleaning of the tubes. Falling film evaporators are therefore used in clean, non-precipitating liquids. A typical application, in chemical industry, is for concentration of caustic soda.

An evenly thin film then enters the heating area with the help of a distribution apparatus in the evaporator. It starts flowing in the downward direction at boiling temperature and gets partially evaporated. The liquid that needs to be evaporated is then uniformly distributed on the inside of the glass tube. The liquid will start to flow down, building a thin film on the inner surface, from where the evaporation process will commence with the help of the heat generated by the steam. The steam will start condensing and will flow down on the outer surface of the glass tube. Some of the tubes are constructed together beside each other. Both the ends of the tubes are fixed to tube plates, and finally, the tube bundle is enclosed by a shell made either of steel or Glass depending upon the steam pressure. The steam is then introduced via shell. The heating section is then formed in the space between the tubes. The inner wall of the glass tubes is known as the boiling section. The vapor and the concentrated liquid collected at the bottom of the evaporator enter the consecutive separator in a tangent position where the concentrated liquid is released via a pump at the bottom. The vapor then leaves the system from the top. Advantages of Falling Film Evaporators Falling film evaporators can also work, keeping a very slight temperature difference between the boiling liquid and the heating media. They also possess a short time for product contact that lasts only a few seconds per pass. Such characteristics help the falling film evaporator become suitable, especially for all the heat-sensitive products, and nowadays, it is acclaimed as the most commonly used evaporator type. Nonetheless, the design of falling film evaporators is done carefully that is suitable for various operating conditions, respectively. If sufficient water is not sprinkled on the heating surface, it will result in having incrustations and plenty of dry patches; and in the worst-case scenario, the heating tubes will get entirely clogged. Falling film evaporators are greatly responsive to all sorts of adjustments of the parameters, including the energy supply, feeding rate, vacuum, concentrations, etc. When you design an automatic control system with the evaporator, they are capable of producing a consistently concentrated product. Designing An ideal design of the liquid distribution system can be crucial to achieving to the fullest, and it can be hard for the product to wet the tubes. Because of its low liquid holding capacity, the falling film evaporator starts its working quickly and easily changes its working mode. Operating Principle In falling film evaporators, the vapor and the liquid flow in the downward direction in a parallel manner. To get the highly concentrated liquid as the product, it must be preheated to the boiling temperature. The evaporated liquid is then uniformly distributed in the glass tube on its inner surface. The liquid tends to flow in the downward direction forming a delicate film, where the process of evaporation takes place due to the heat generated by the hot oil. This hot oil is then brought in through the shell. Size and Available Models Falling Film Evaporator are available in the Heat Transfer Area of 2 Sq. Mt to 20 Sq. Mt. and from 4″ to 12″ in diameter and larger sizes available on request. Final Thoughts We are Ablaze Export Pvt. Ltd., the leading Falling Film evaporator manufacturer in Vadodara, Gujarat.

Falling Film Evaporators, water is boiled in a sequence of vessels, each held at a lower pressure than the last. Because the boiling point of water decreases as pressure decreases, The vapour boiled off in one vessel can be used to heat the next, and only the first vessel (at the highest pressure) requires an external source of heat. This is called multiple effect and no of stages / effects is depend on quantity of vessel / calandria in sequence.Theoretically, one kg of steam evaporates one kg of water. In multiple effect evaporator, one kg of steam evaporates up to 6 kg of water by no of effects and vapour recirculation by thermo vapour recompressor. It is called as steam economy 1:6. Feed is preheated to nearby boiling temperature in Pre heater that connected with all calandria. All calandria are operated at stage by stage vacuum with reduced temperature. So feed is preheated by stage wise from lower temperature to higher. Then it is passed via first calandria tube bundles as fine film layer over the tube surface area. In shell side fresh Steam is given via Thermo Vapour Compressor. Feed is heated and evaporated in calandria. Evaporated Vapour is separated in Vapour Separator, vapour is sent to second calandria Shell side. Un evaporated feed is transferred to second calandria tube side.Here further evaporation is done. So each calandria evaporates feed and concentrate coming out from last calandria. In this system, concentration is achieved by stage by stage and each calandria have higher concentration as stage increases. A part of evaporated vapour is recycled to first calandria via thermo vapour recompressor. In Thermo Vapour Compressor, Fresh Steam with pressure is passed via steam nozzle. Steam produce high velocity and produce a venturi Effect.This will recirculation a part of evaporated vapour.

We are also betrothed in offering to our clients, a consignment of Falling Film Evaporator. Features : User friendly Effective performance Energy competent Low Operation Cost High Product Quality Compact Design falling film evaporator is an industrial device to concentrate solutions, especially with heat sensitive components. Details : In falling film evaporators, liquid and vapors flow downwards in parallel flow. The liquid to be concentrated is preheated to boiling temperature. An even thin film enters the heating tubes via a distribution device in the head of the evaporator, flows downward at boiling temperature, and is partially evaporated. This gravity-induced downward movement is increasingly augmented by the co-current vapor flow. Falling film evaporators can be operated with very low temperature differences between the heating media and the boiling liquid, and they also have very short product contact times, typically just a few seconds per pass. These characteristics make the falling film evaporator particularly suitable for heat-sensitive products, and it is today the most frequently used type of evaporator. This type of evaporator is generally made of 48 m (1326 ft) tubes enclosed by steam jackets. The uniform distribution of the solution is important when using this type of evaporator. The solution enters and gains velocity as it flows downward. This gain in velocity is attributed to the vapor being evolved against the heating medium, which flows downward as well. This evaporator is usually applied to highly viscous solutions, so it is frequently used in the chemical, food, and fermentation industries.

One can avail Falling Film Evaporators from us at the most nominal prices in the market. Description : Falling film evaporators based on shell & tube heat exchangers are available for the evaporation of temperature sensitive substances and those tend to form useless residues by condensation or polymerization. In falling film evaporators, liquid and vapors flow downwards in parallel flow. The liquid to be concentrated is preheated to boiling temperature if require. An even thin film enters the heating tubes via a distribution device in the head of the evaporator, flows downward at boiling temperature, and is partially evaporated. The liquid to be evaporated is evenly distributed on the inner surface of a Glass tube. The liquid will flow downwards forming a thin film, from which the boiling/evaporation will take place because of the heat applied by the steam. The steam will condense and flow downwards on the outer surface of the glass tube. A number of tubes are built together side by side. At each end the tubes are fixed to tube plates, and finally the tube bundle is enclosed by a shell made either of steel or Glass depending upon the steam pressure. The steam is introduced through the shell. The space between the tubes is thus forming the heating section. The inner side of the glass tubes is called the boiling section. The concentrated liquid and the vapour leave the evaporator at the bottom part, enters the subsequent separator tangentially from where the concentrated liquid is discharged (usually by means of the pump) from the bottom and vapor leave the separator from top. Falling film evaporators can be operated with very low temperature differences between the heating media and the boiling liquid, and they also have very short product contact times, typically just a few seconds per pass. These characteristics make the falling film evaporator particularly suitable for heat-sensitive products, and it is today the most frequently used type of evaporator. However, falling film evaporators are designed very carefully for each operating condition; sufficient wetting of the heating surface by liquid is extremely important for trouble-free operation of the plant. If the heating surfaces are not wetted sufficiently, dry patches and incrustations will occur; at worst, the heating tubes will be completely clogged. The proper design of the liquid distribution system is critical to achieve full and even product wetting of the tubes. This is specially designed by ‘Super’. Because of the low liquid holding volume in this type of unit, the falling film evaporator can be started up quickly and changed to cleaning mode or another product easily. Falling film evaporators are highly responsive to alterations of parameters such as energy supply; vacuum, feed rate, concentrations, etc. When equipped with a well-designed automatic control system they can produce a very consistent concentrated product.
