Kumar Solvent Extraction Plant

Kumar Solvent Extraction Plants are continuous and fully automatic intended for medium and large scale processing. A modern desolventizer  Toaster has always been standard equipments in the  plant for better de- solventization and biological value of metal is achieved by the Desolventizer toaster apart from incorporation more stable moisture

Kumar Solvent Extraction Plants are known for efficiency, modern design and a continuous process of up gradation and other sales service at par with international standards

We have a joint venture with Crown Iron works USA and Europa Crown, UK to manufacture Solvent Extraction Plant of higher capacity based on their Technical backup.

Salient Features for Kumar Extraction Plant

1.   Extraction :  

 §  Circulation system is developed to have better solvent meal contact to have   optimum recovery  of oil.

§  Better draining time is provided to reduce solvent contains in the extracted meal which will reduce the load on the D.T.

§  Special rinsing and back washing system to keep the band conveyor clean which will provide better percolation and avoid flooding i.e. better extraction.

§  Special fines separation system is provided to reduce fines in the final miscella which ultimately help to reduce load on the distillation system and will give solvent free oil with minimum fines and sludge.

This also help to avoid scale formation in the distillation system and help to minimize over heating of the oil and reduce utility consumption.

§  Specially designed condensation and recovery system help in maximum heat utilization and reduce load on condensation, which ultimately reduce solvent loss.

§  New vent vapour recovery system help in better recovery of solvent from vent vapours.

§  Provision of special cooling system to help to produce final oil at 10-15°C above the ambient temperature, which will prevent  oxidation and colour fixation of the oil.

• Desolventiser toaster is to be provided with hollow shaft steam connections to the blades to facilitate injection of steam in the material through moving blades. This ensures the intimate contact of steam with meal and effective transfer of latent heat to accelerate evaporation of hexane. This system ensures the highest contact ratio between sparge steam and meal to be Desolventised per unit area
• Another advantage of sparge steam through blades is, it reduces the number of steam injection nozzles and free working space and operator friendly system, which allows precise controlling of quantity of steam by one valve
• DT outlet duct is designed to get the vapor velocity sufficient to cyclonic separation. Wet dust catcher is specially designed with incorporated cyclone separator and Vapors thoroughly washed with water sprays for removal of dust particles. This high efficiency cleaning provides trouble free running of heat exchangers
• The provision of plug-o-seal conveyor with variable speed drive at outlet of desolventiser ensures sealing of system. Thus eliminating the possibility of air entry into the desolventiser toaster
• DT vapor outlet is routed through various heat exchangers. The condensers and economizer are so designed to achieve minimum pressure drop (across shell)
• Zero vent system is a unique feature of Kumar system to minimize the loss of hexane to the atmosphere through final vent. In this system additional in line steam jet ejector is incorporated to provide pull to the vapors, which allows the vacuum in DT Vapor outlet duct up to 25mm of water column. This ensures the effective removal of vapors from DT without any reflux. Exhaust of final vent steam jet ejector is passed to extractor through direct contact type condenser and exhausted to atmosphere through feed bin of extractor. This reduces the amount of hexane going to atmosphere along with air
