Soya Solvent Extraction Plant
 
 
Soya Seed Preperation
 
A good seed preparation is very critical to good extraction. Oil seeds are first cleaned and the destined before processing. The cleaned seeds are then cracked in cracking mills having specially designed rolls.

The rolls are grooved and have surface hardness. The cracked beans are then carefully cooked and flaked in hydraulic flakers to produce uniform flakes. These flakes are then transported to the extraction plant for further processing.

 
 
Solvent Extraction
 
Soya flakes from the preparation section are fed into an Extractor with stainless belt. Level in hopper is controlled through an ultrasonic level controller which regulates the speed of the extractor.

Miscella is filtered through special wedgewire filters.

Distillation comprises of a series of heat exchanges for heat recovery and evaporation of hexane. The oil is finally stripped in a special stripper operating under low vacuum. Series of specially designed condensers with tubes of stainless steel are used for condensing the hexane vapors for recirculation.

The vent gases are 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 vapor 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 anti nutritional factors.

The meal is subsequently dried and cooled for bagging.
