Scraped Surface
Scrapped surface Evaporator is used for evaporating the heat sensitive material under high vacuum using thin/scraped film technology. Thin film yields high heat transfer coefficients, making the process highly effective.
Our evaporators are ideally suitable for concentrating a range of solutions / suspentions including highly heat sensitive liquids where original properties of the product have to be preserved and the stability of the product is vital.
We offer custom built plants, which can be specially designed and sized to optimize the operation cost vis-a-vis the initial investment. Single or multiple effect system using falling film, scraped surface and forced circulation either alone or in combination can be offered to meet product requirements.
The system can be offered as a package unit inclusive of pre-heaters, thermo compressors, vapour separators, transfer pumps, vacuum pumps and condensers and solvent stripping units.
Full Array of Evaporators
We build our evaporators with meticulous design and manufacturing procedures to suit each and every specific application in mind. May it be highly temperature sensitive product or highly fouling and sealing product. Or, it may be a specific requirement of reducing operating costs. All requirements are assessed and need fulfillment is incorporated at the design stage itself.
The appropriate combination of Falling Film, Forced Circulation, Scrapped Surface type Evaporators along with Thermo vapour Re-compressor, Condensate and Product Flashing designed optimally, delivers the best efficiencies and ensures least operating cost.
Accessories
Condensate and product Flashing
By flash pulling the outgoing streams like product and condensate, maximum heat recovery within the system is ensured and that accounts for substantial steam reductions.
Thermo vapour Re-compressor
They ensure reuse of evaporated vapours and thereby account for a good reduction in steam requirement, almost equivalent to one additional effect.
