A rising film or vertical long tube evaporator is a type of evaporator that is essentially a vertical shell and tube heat exchanger.

Moreover, rising film evaporators requires a driving force to move the film against gravity and this causes a limitation because there is a requirement for a sufficient temperature difference between the heating surfaces to provide the driving force.

High heat transfer coefficients: Residence time indicates the time taken for the product to undergo the entire procedure.

Semi kestner, also known as semirising film evaporator, is widely used in sugar industries. Email to friends Share on Facebook – opens in a new window or tab Share on Twitter – opens in a new window or evsporator Share on Pinterest – opens in a new window or tab.

Various researchers define parametric modeling and design in their own way. Representative APR variable Archived from the original on This evaporating system is based on the theory that when in a tube, no matter what may be its position and its diameter.

Equipment has been developed in an attempt to overcome one or more of these problems. Feed ring design feed distribution pattern the distribution of feed within an evaporator has a great impact on the flow pattern within the robert evaporator pennisi et al.

As such to assess the performance of a rising film evaporator, the capacity and thermaleconomy of the evaporator is measured. Powered by eBay Turbo Lister. Report item – opens in a new window or tab.

In the evaporator assembly i employ a series of connected falling film type evaporator units, each unit including a vertical tubular evaporator having a shell ii and a nest of tubes such as l2 which are retained in the upper and lower tube sheets l3 and l4. The vaporliquid mixture travels down the remaining tube length and into the vapor head.

In general, the greater the temperature difference, the better evaporrator driving force of the steam. Juice kester and food processing: My invention evaporatoor to concentrating or evaporating apparatus, and has reference to an improved evaporator to be used for concentratin liquids and is especially useful for such liquids as cause scaling on the heating surfaces and alsofor such liquorsfor example, glue, gelatin, extracts of various kinds and even sugar juices, which are likely to be injuriously ‘afiected if allowed to remain for any length of time in stationary contact with a heated surface.

This factor will determine the capacity of the rising film evaporator. The limitations for these can be in terms of the cost per unit area as increasing the area would mean increasing the length of the tubes and also the shell of the evaporator which can significantly increase the cost of construction and maintenance.
