Complete crude vegetable oil refinery for the production of edible oil General: Complete factory for sale because of strategic decision to outsource the production. Production stopped in 2014. For sale per direct. Lines are still mounted in their original position in Bratislava, Slovakia. Dismantling and transport is excluded in the price but can be offered separately. Offer is based including all interconnecting piping, valves, control panels and instruction manuals/electric schemes, whatever is available. Technical details: - Degumming line Degumming, by passing hot water through the oil to precipitate out gums and proteins that are soluble in water but not in oil, then discarding the water along with the impurities (eliminate Lectine from the oil). The crude oil is initially heated to the optimum process temperature and a small quantity of fosforic acid is added. Following intensive mixing and a brief reaction time, after them some of the acid is neutralized with dilute caustic soda. After mixing in a centrifugal mixer, the gums are separated from the oil in a centrifuge. Because very fine phosphatide particles cannot be separated, a certain amount of water is again added to the oil. Following a brief reaction time, the mixture is conveyed to a high-performance clarifier – separator, which is able to generate an extremely high g-force thanks to its special design. This enables the fine particles to be continuously separated with the water. In order to avoid oil losses, this phase is recycled into the feed of the first centrifuge, where the fine gum particles are separated together with most of the phosphatides. The oil which is degummed in this way is subsequently dried. Lecithin - phosphatide is a side-product, which is used in animal feed. Raw oil is pumped out of the tanks via a plate exchanger where it is heated to a required temperature. Quantity of oil flow is measured by a flow meter. Behind an exchanger, a diluted phosphoric acid is dosed into oil, consequently dispersed in a special mixer. Oil with the acid is pumped via an acid reaction tank where phosphatides are being flaked. Behind the tank, the part of acid is neutralized by diluted caustic soda. Behind a centrifugal mixer providing perfect hydroxide dispersion in oil, the oil is transported to a special separator where phospholipids, slimes and impurities are separated from oil. Washing water is dosed into slime-free oil and mix through a mixer and a tank is transported onto the second jet filtering separator. Water with soft phosphatide parts is separated on this separator; a part of oil leaves partly through the separator jets too. This mixture is diverted into a tank under the separator from where it is pumped ahead of the first separator. Oil from the washing separator is pumped through a vacuum drier into a tank onto slime-free oil. Slime-free oil is pumped from an operation tank via a flow meter and an automatic sampler into storage tanks in the oil store room. Benefits of this process: • P-content < 10 ppm possible • Short retention times • Very compact installation

2x Refineries with winterization and pre-esterification In the refinery operation technologic processes are carried out and in oil dissolvent substances are removed from edible oils and fats (free fatty acids, natural colors, waxes, aromatics and non-food flavors). Other technologic processes follow, and oil physical characteristics are changed. Neutralization The oil is initially heated to the optimum process temperature. Following step - dilute caustic soda is added in order to neutralize the free fatty acid in oil. After mixing with the oil, the mixture is either conveyed directly to the first self-cleaning separator used for separating the sodium soap. However, the residual soap content in the neutral oil is still too high for the subsequent process stages, and it must therefore be further reduced by washing step. For this purpose, hot water is added to the oil and intensively mixed. The soapy wash water is removed in a further separator. Depending on the subsequent bleaching method, the neutralized and washed oil is subsequently vacuum-dried. Soapstock splitting Processing of by-products, during the chemical neutralization of oils and fats, so-called soapstock (sodium soaps of the free fatty acids) is obtained as a by-product. This by-product must be split into fatty acids and water by means of acidification with strong acids (sulphuric acid). After this process, two phases are formed - fatty acids and acid water. Fatty acids are a valuable product in the animal feed, soap and oleochemical industries. Acid water after end the process must be and cooled off and neutralization with sodium hydroxide Deodorization Most oils, even after refining, have characteristic flavours and odours. The deodorization process consists of blowing steam through heated oil held under a high vacuum. Deodorization is a high-temperature, high-vacuum steam-distillation process to remove volatile, odoriferous materials and free fatty acids present in edible fats and oils. Lurgi deodorization is a semi - batch process, Krupp deodorization is continuous system. In the deodorization plant, bleached oil is usually heated progressively to deodorization temperature using hot refined oil and high pressure steam. The hot oil is then fed to the stripping section of the U-Column; where free fatty acids are stripped off from the oil by steam over the large surface area. Deodorization temperature of 175°– 235° C is

common. About 0.01 percent of citric acid is commonly added to deodorized oils to inactivate trace-metal contaminants such as soluble iron or copper compounds that otherwise would promote oxidation and the development of rancidity. The vapour from the stripping section is condensed and collected in the scrubbing section while pre-stripped oil is transferred to the deodorization section. In this section, the oil flows by gravity through a series of trays, where steam is injected through mammoth pumps or sparger pipes. After deodorization, the oil comes out neutral, without any taste or smell remaining from the source plant and free fatty acids content is very low. Edible oil refining can be broadly divided into two routes: chemical refining and physical refining. Deodorization is needed in both of these routes, but for slightly different reasons: 1. For Physical Refining, the role of a deodorizer is:

Stripping of Free fatty Acids

Deodorization

Heat bleaching

By-products of the distillation are fatty acids ( by – product ) 2. For Chemical Refining, the role of deodorizer is:

Deodorization

Heat bleaching The different stages in deodorising are :

Deaeration Heating Deodorising / steam stripping Heat recovery / cooling Final cooling Polishing filtration

Following refining methods are available: 1. Alkali refinery ( or classic chemical refining ) – the standard steps in this process are: – neutralization ( acid conditioning, refining with caustic lye, washing with water, drying under vacuum); – bleaching under vacuum for improving the color of oils and fats and remove many impurities; – deodorizing; – splitting – soap stocks acidulation. 2. Physical refining: – bleaching under vacuum for improving the color of oils and fats and remove many impurities; – deodorizing. 3. Winterization of sunflower oils is a process of removing the higher melting point parts from the oil like waxes or triglycerides by slowly cooling vegetable oils and felling saturated glycerides from the solvent, dewaxing: – wet winterization / dewaxing – acid conditioning, hot refining or using of surfactants, cooling, dewaxing, washing, vacuum dying; – dry winterization / dewaxing – cooling, filtration.

Winterization Krupp winterisation - for this purpose, the sunflower oil is cooled and allowed to crystallize for several hours. It is then filtered using filter aid ( cellulose ).The basis of winterization is the cooling down of oil, which causes unwanted wax to crystallize. This process occurs in several steps: first, the oil is pumped into the initial crystallizer, equipped with a cooling system. Then the oil flows downstream into the second crystallizer, where crystal cores form. Afterwards, the oil flows further into the last crystallizer, where a cooling system maintains constant temperature, at which the remaining wax particles aggregate with the crystal cores. In the final phase of the process, the crystals that have formed are separated out on a horizontal filter by using filter aid ( cellulose ).. What flows through is pure, winterized oil; wax fixed on cellulose falls out in a discontinuous manner. Main items:
