To provide a properly reasoned op inion on the advisability of using clear juice heaters, it is.

Find your liquid evaporator easily amongst the 44 products from the leading brands bronkhorst, ika, horiba stec. This design is created to re-concentrate a diluted solution to its desired concentration by evaporation while also allowing evaporated water evaporayor condense simultaneously and be recovered for either recirculation or other purposes.

With the-liquid fed into the base of t e auxiliarypan B,’as ‘ is preferably done, it receivesits first neatmg and evaporation therein, and deposits v whatever scale forming bodies it carries in which is impossible with the ordinary type of vacuum an, as -for instance’ an A.

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. The fundamental general formula which gives the overall heat transfer rate is, [3].

As shown in the equation, the heat transfer area is one of the chief factors that affect the rate of conductive heat transfer. If the tube be vertical and the circulation takes place from the bottom toward the top, the phe. Contact the seller – opens in a new window or tab and request a postage method to your location.

Semi Kestner Evaporator

Although no conclusive correlation for the optimum. This is accentuated by the fact that the components, which consist of a shell and kestnee, are easily obtainable with customized designs making them cost effective for construction and ideal for simple evaporation requirements.

People who viewed this item also viewed. Rising film evaporators can operate quickly and efficiently enough to avoid having to expose the product to evaporatorr temperatures which may damage or undermine its quality.

Parametric design and modeling of semi kestner evaporator for. Some of the problems arising during evaporation include.

USIPL – Semi Kestner

Semi kestner, also known as semirising film evaporator, is widely used in sugar industries. This would give higher heat transfer coefficients and overall heat transfer rate. Additionally, having a high temperature evaproator will also increase the flow rate of the liquid and vapour within the tube.

Competitive process designs like plate-type evaporators can handle liquids that are more viscous with higher fouling tendencies because fvaporator inner parts are more easily accessible for cleaning and maintenance.

See all condition definitions – opens evaoorator a new window or tab. Juice concentration and food processing: This phenomenon of the rising film gives the evaporator its name.


In the present application of this system the liquid and vapor evpaorator returned to the main pan. The improved form of evaporator which I have combined with the old type of concentrating apparatus employing vacuum pans in single or multiple effect, relates to preferably in the form of steam is admitted to reduce the water content of the liquid under process of treatment.


Evaporators visual encyclopedia of chemical engineering. We do not deal in facsimiles or reproductions of any kind. This evaporating system is based on the theory that when in a tube, no matter what may be its position and its diameter.

The umzimkulu uk and sezela sz kestner design data, together with the current operating data, are given in table 1. This factor will determine the capacity of the rising film evaporator. This can be solved in various ways such as having a pre-heating system prior to the main evaporator with the function of heating the liquid feed until the temperature almost approaches the boiling point. In order to maximise the thermal economy it is generally acceptable to maximise the heat transfer area as a larger area would give a higher heat transfer rate.

Shanghai College of Textile Technology, China. This is the total contact area between the heating media and the liquid requiring the heating or any intermediate surfaces in between them.

To all whom it may concern: Hence, they are suitable to use as concentrators for juices, milk and other dairy products which are products that require delicate kestber in the food industry.
