By reason of the relatively long and narrow form of the auxiliary pans, they may be directly attached to the ordinary pans, without use of floor room, and, with multiple effects they may be advantageously placed in the angles between the several eifects.

Experiences kesyner the balckediirr fallingfilm plate. Thisar-rangement results in a complex s stem of circulation. To this end, I add to the old type pans certain novel and peculiar auxiliary evaporating devices whereby liquid and steam circulation are made positive and automatic, even in badly designed pans, and entrainment is prevented, and whereby the evaporative capacity of the’plant is enormously increased.

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. Juice concentration and food processing: The Full Size of the page approximately This is the total contact area between the heating media and the liquid evaporxtor the heating or any intermediate surfaces in between them.

To allow this alternative to be evaluated on a quantitative basis, available data on the relative heat transfer performance of juice heaters and kestner evaporators have been collated, providing.

This is crucial because it allows the usage of the evaporator in higher operating temperatures and gives assurance of high product quality despite the product being heat sensitive. Designed inhouse kestneg sris worldrenowned experts, sri robert evaporator designs improve performance for sugar mills and refineries that are dependent on vapour bleeding for juice heating or pan stage boiling. Two pages with highly detailed schematic diagrams and accompanying article.

This is essential in order to ensure that the optimal product is obtained while maximising the efficiency and cost effectiveness of the design. This ksstner occurs under vacuum conditions that allow for the use of lower temperatures.

We accept PayPal payments from buyers all over the world. The fundamental general formula which gives the overall heat transfer rate is, [3]. Semi kestner, also known as semirising film evaporator, is widely used kfstner sugar industries.

The temperature difference for driving force is also defined heavily by the properties of steam and the boiling liquid. In relation to that, the Artisan Rising Film Evaporator is designed to eliminate the majority of the volatile components before stripping and is usually used as a flash evaporator or pre-heater.

Skip to main content. The Artisan Rising Film Evaporator has similar basic fundamental as the general design of a long-tube vertical evaporator, but it is modified to allow for handling of more viscous and volatile material which the orthodox design may not be able to handle due to excessive fouling. The hot fluid in the case of the rising film evaporator would be the steam in the shell side and the cold fluid would be the liquid inside the long tubes.

Semi Kestner Evaporator

There is a wide range of applications for rising tube evaporators, including effluent treatment, production of polymers, food production, thermal desalination, pharmaceuticals, and solvent recovery. Hence, they are suitable to use as concentrators evalorator juices, milk and other dairy products which are products that require delicate handling in the food industry.

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

Beyond this point, the temperature difference, which acts as the main driving force for the heat transfer and also the rising film, will start reducing if there is any increase in steam pressure. In falling film evaporators require uniform and adequate wetting of the tubes and so need the complication of juice recirculation and a distribution system feeding equal quantities of juice to every tube.
