Defatted White Soya flakes required for manufacture of Textured Vegetable Protein, Protein Concentrates and Protein Isolate manufacture can be manufactured only in a Flash Desolventising System. The flash desolventising system is capable of achieving the highest possible Protein Dispersibility Index at the upper end of the desired range.

In the FDS a dry dehydrating temperature prevails and the temperature of the flakes is no higher than the boiling point of the solvent and the retention time is a few seconds.

The least denaturation of the flakes takes place and PDI levels upto 95% of that of the incoming material are achieved.

The flash loop consists of carefully designed transport tube where superheated hexane vapous are circulated by means of a special blower in sparkproof design and equipped with special labyrinth seals.

The temperature and pressures in the system are carefully controlled by a fully automated system.
The Solvent wet flakes from the extractor are metered into the desolventising tube using special rotary valves.

The desolventised white flakes are seperated in a specially designed cyclone nom where they are removed to a stripper and then transported for bagging.

The hexane vapours are scrubbed in special scrubbers to avoid fouling and then passed to the distillation section.
