Winterization is a narrow process, it same as that of dewaxing. This process is applied to remove small quantities of solids from oil that would normally cause cloudiness of the oil when keep at refrigeration temp, these substances can be saturated glycerides or waxes. Waxes are esters of fatty alcohol and fatty acid, which have a very low solubility in oil. There quantity is different in different oils. Generally varies in between 48-2000 ppm. In order to obtain oil with good cold stability, the waxes contain needs to reduce to the level of about 10 ppm. In this process cooling rate & agitation are carefully controlled to promote the formation of nuclei that will serve as the sites for crystal growth.

Vegetable oil is properly refined for complete removal of waxes, gums (phosphatides) and free fatty acid. After refining. The oil is filtered from various impurities, odor and viscous pigments, thus gets a uniform color. In the plant, there can be batch refining or continuous refining as per the requirements of the applications. Incorporated with latest technology, the vegetable oil refining plant is specially designed with different processes, all integrated in a single compact unit. The plant is assembled with a bleacher, neutralizer, heat exchanger, and deodorizer, filters and high & low vacuum equipments.   We are the forerunner in the industry for introducing advanced distillative deacidification technique (physical refining) in the vegetable oil refining. This is an innovative technique introduced that has the capability to totally eliminate the caustic treatment with all its attendant disadvantages. We also hold expertise in manufacturing pressure leaf filtration system that is specially engineered for flow rates. FEATURES  Energy efficient operation  Optimum consumption of chemicals  Continuous operation with automatic loading  Desolventizer toaster is used as standard equipment  Integration with advanced process control system and efficient plant performance  Ensure high flow rate  Wet bleaching for lower earth cost  Consistent product quality and output

Generally used as the alternative to ghee due to its cheap price, Vanaspati is vegetable cooking oil, fully or partially hydrogenated. Our expertise lies in manufacturing and developing hi-tech vanaspati plants for complete processing and production of oil. The vanaspati is either used for cooking food or as the raw compound in soap making. We have a reputed track record in the industry with successful installation,We are equipped with advanced technology that facilitates us to develop special types of industrial hard oil plants, attached with hydrogenation gas generation system. This system produces hydrogen gas by the electrolysis of water. Required for the hydrogenation reaction the gas is compressed in storage cylinders in which high pressure is maintained from where It is drawn for use in the processing plant.

The solvent extraction plants are used where oil is extracted from oil seeds like Rice bran, soybean, sunflower, cottonseed. Other oil cakes like groundnut cake, mustard cake.  Preparatory section  Extraction section  Conditioning section  Distillation section  Recuperation section PLANT CAPCITY The plants are ergonomically designed and are energy efficient, consistent in output quantity and quality, operator friendly and generate less effluent. The level of plant automation depends upon client requirement. PROCESS The process of solvent extraction results into a solution of the oil in solvent by diffusing solvent into the oil-bearing of raw material. Different types of solvents can be used for this purpose, but among all those, hexane is extensively used in the solvent extraction due to its low boiling point.

SES AGROTECH PROJECT ENGINEERS PVT LTD new generation physical refinery plants are ideal solution for minimizing processing cost & processing loss. For high FFA oils such as palm oil & Rice bran oil this process is most common.    

Deodorizing is nothing but the Distillation process, in which fatty acid is distilled from oil. Under high temperature conditioning and in presence of high vacuum, with the help of sparging & agitation steam. Further this fatty acid in vapors form, is condensed & recovered in liquid form by the vapors scrubbing system. De-waxed/Bleached oil from intermediate storage tank is pumped by to primary heating plate heat exchanger, which is used only in startup conditions. To heat the incoming cold de-waxed oil. Further it will be travel from oil to oil heat exchanger. Where de-waxed oil is getting heated by the outgoing hot refined oil. Then this oil is going to the pre-heater via. Peripheral coils of the regenerative heat exchanger which is the bottom compartment of the multipurpose deodorizer. In regenerative heat exchanger de-waxed oil flows through the coils & refined oil flows through the open space of the exchanger. In counter current manner, continuous steam agitation at open steam side assures continuous and maximum heat exchange. After recovering maximum final heater this heater is equipped with agitation and sparging steam, continuous flow of superheated steam through this assures effective primary vaporization of fatty acid.   Further this overflows to the multi-compartment DEODORIZER, Deodorizer is multi-compartment vertical vessel, where each and every trays are specially designed which ensures uniform distillation of odoriferous substances. Oil is overflows from tray to tray. Specially designed trays provide sufficient mass transfer surface for effective removal of volatile matters. Flow control system at the outlet of the deodorizer, ensures the maintenance of required level at the bottom tray. The steam used for stripping off volatile matters in the oil is distributed evenly and intensively the steam meets the deodorized oil. Stripped off the volatile matters and rises through the vacuum. Stripping the volatile matter form the oil. The counter-current flow of steam and oil like this in specially designed trays lower steam consumption, than the conventional deodorizers. The deodorized oil leaving regenerative heat exchanger and finally cooled by water in heat exchanger finally this oil is passed through the alternatively operating se of polishing filters. VAPOUR SCRUBBING The volatile matters consisting of free fatty acid and other odoriferous substances stripped from the deodorizer are led to the vapor scrubber located at the outside of the deodorizing column. In the scrubber volatile material rises through the bed of pall rings and meets liquid fatty acid sprayed from the top. Vapors are condensed, cooled and then recalculated to condensed fresh vapors. Excess distillate collected is led to the storage tank, whenever high level reached in storage space below the scrubber. Fatty acid scrubber is specially designed for minimum carryover of fatty materials, to the vacuum system.

The acid oil plant ensue a continuous and automated operation.
