Vapor tight construction in carbon steel, for de-solventising as well as toasting, specially designed for oilcake and comprising of a number of stages with bottoms jacketed for the purpose of indirect heating. Centrally rotating shafts provided with scrappers along with sparge steam distribution to ensure uniform heating and movements of the materials in the stages. Fitted with indicators to indicate the level of material in the stages. Final discharge door is later connected with the feeding, complete with driving mechanism. With Pneumatic Meal Level Controlling arrangement.
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.

To correctly cook and condition the material prior to Flaker. Vertical, multi-stage unit with fabricated shell and trays where heating is carried out by indirect steam. The gates operated by mechanical level system automatically control the flow of material and the level in each stage. A central shaft driven by a gearbox carried agitator blades to ensure a good mix, a homogenous treatment of the material and prevents burning on the stage bottoms. A vertical duct extracts exhaust vapors from each stage. Provision is made to adjust final moisture levels of the material by injecting water or direct steam.
As a Refinery Plant, Vegetable Oil Processing Plant etc.
The suction load data of each steam jet ejector is precisely calculated which ensures lowest possible consumption of steam, thus reduction in recurring expenses along with reduction in heat load on condensation system.
Distillation is carried out in three stages of vacuum. There by achieving incremental concentration of miscella at predetermined rate. Further more each stage is differentiated by incorporation of precisely designed U type siphon pipe, eliminating the use of centrifugal pump. This ensures continuous flow of miscella, & reduces power consumption.
Economizer is specially designed having built in flasher, which provides the compact design, Minimum plant space and reduction in unwanted piping. This design itself provides the high efficiency flashing which increase the miscella concentration up to 75%.
The final stage striping is carried out in presence of steam under higher vacuum of 700 mmHg. This allows the lower temperature distillation and they’re by ensuring undamaged crude oil without color fixation.
