Sunflower Seed Oil Press Solvent Extraction Refining Equipment

Sunflower oil is the non-volatile oil pressed from the seeds of sunflower (Helianthus annuus). Sunflower oil is commonly used in food as a frying oil, and in cosmetic formulations as an emollient. The world's total production of sunflower oil in 2014 was nearly 16 million tonnes, with Ukraine and Russia as the largest producers.

Sunflower oil is a monounsaturated (MUFA)/polyunsaturated (PUFA) mixture of mostly oleic (omega-9)-linoleic (omega-6) group of oils. The oil content of the seed ranges from 22% to 36% (average, 28%): the kernel contains 45-55% oil. The expressed oil is of light amber color with a mild and pleasant flavor; refined oil is pale yellow. Refining losses are low and the oil has good keeping qualities with light tendency for flavor reversion. The oil contains appreciable quantities of vitamin E, sterols, squalene, and other aliphatic hydrocarbons.

Genome analysis[2] and development of hybrid sunflowers to increase oil production are occurring to meet increased demand for sunflower oil.

Our Technology Features:

The whole plant adopts waste heat utilization technology. In every section, set energy-saving heat exchanger, finished oil at high temperature to do heat exchanging with bleaching oil, dry oil and crude oil in turn from high to low according to different process temperatures, which can make maximum use of waste heat of deodorization finished oil,reduce steam consumption. All steam condensate water of heating equipment is recycled into hot water tank for reuse.

Drying of water washing oil adopts vacuum drying technology, compare with traditional technology, not only reduce steam consumption, but also prevent oil from contacting air,reduce oil oxygenation efficiency, keep the maximum inherent nutrition value.

When blow bleaching clay,design odor trapping device, use circulating water cooling to catch odor of blowing steam, remove odor pollution in the decolorization process, meet environmental requirement.

Set self-spraying device in waste bleaching clay room, spray cooling water when discharging cake from filter, ensure effective cooling of bleaching clay, avoid spontaneous combustion of bleaching clay, play a role safe production.

The crystallization tank adopts vertical structure internal stirring system,with advantages of long crystallization time, large crystal particles and good dewaxing effect.

The entire workshop is fully automated, and all key control points such as temperature, pressure and liquid level are displayed on the computer and automatically controlled.
