Flakes nom the preperation section are fed into an Extractor
with stainless steel belt. Level in hopper is controlled through
an ultrosonic level controller which regulates the speed of
the extractor.
Miscella is filtered through special wedgewire filters.
Distillation comprises of a series of heat exchangers
for heat recovery and evaporation of hexane. The oil is finally
stripped in a special stripper operating under low vacuum.
Series of specially designed condensors in tubes of stainless
steel are used for condensing the hexane vapours for recirculation.
The vent gases are specially scrubbed with mineral oil before
Discharge into the atmosphere. The hexane content of the gases
leaving the system are well below the lower explosion limits.
The solvent wet meal is fed through a vapour tight conveyor
into Desolventiser Toaster equipped with special level controllers.
Here the meal is desolventised in a series of stages and subsequently
toasted to remove the antinutritional factors.
The meal is subsequently dried and cooled for bagging.
