corn germ oil processing supplier

Corn germ is a kind of high oil-containing oilseed. Corn oil is a healthy cooking oil which can be used for deep frying. Corn oil is rich in linoelic acids and other PUFAs ( polyunsaturated fatty acids )，corn germ oil is good for heart health.

Corn germ oil process includes corn germ, cleaning and weighing, softening, flaking, pressing, cake, cooling, extraction plant, crude oil, filtration, filtered oil, refinery plant.

Henan Huatai undertook corn germ oil project,Henan Huatai Cereals&Oils Machinery Company Limited is a large scale oil machinery manufacture enterprise integrated R&D, design,manufacture and installation.and have created a number of science and technology achievements and patented technology products in oil machinery field.our products sell well in more than 30 provinces, cities and districts, and are exported to Bolivia,Sudan, kazakhstan,Tajikistan, Malaysia, Russia, Zambia,Vietnam,Thailand,Indonesia and other countries and regions, and now we have developed into a major oil machinery manufacturing base in China.

corn germ oil extraction

Corn/maize germ is the raw materials of the oilseed press. There is germ 8-10 kg in every 100 kg of maize, the corn germ oil that squeezing from the corn germ is called corn oil, also called corn germ oil.Corn oil has good effect to cardiovascular disease, eat corn oil, easy be absorbed by human body, the digestive rate is more than 97%.Corn germ oil, is a refined vegetable oil obtained from the germ of corn plant, corn germ oil is one of the plant oils that accumulate the highest levels of unsaturated fatty acids in the triacylglycerol fraction.

Basic step for all the processes is inspection and cleaning. The shipments are inspected for contamination and cleaned thrice to remove cob parts, dust, chaff and other materials before steeping, the first processing step begins. In this step of steeping, clean corn grains are soaked at 50°C water in big steel tanks . During this process the grains swell and soften. After steeping, the corn is coarsely ground to break the germ loose from other components. The ground corn, in water slurry, flows to the germ separators. In this process of germ separation, cyclone separators spin the low density corn germ out of the slurry. The germs are pumped into a screen and washed separately to remove stray amount of starch in the mixture. Oil is recovered from corn germ by expelling, solvent extraction or a combination of expelling and solvent extraction. Wet milled germ is preferably expelled from an oil content of 50-60% down to 20-25% and finally extracted with hexane to a residual oil content of 1-2% in the spent corn germ flakes. The oil is then refined and filtered into finished corn oil.

Crude corn oil contains 95% triglycerides besides containing minor compounds like free fatty acids, waxes, phospholipids, pigments, and odourous compounds. Before making the corn oil acceptable to the consumers these components are removed from the crude oil through a refining process. This process involves several steps:formation of sodium soaps of the free fatty acids,  removal of the emulsion containing the soaps and phospholipids by centrifugation,  removal of waxes by chilling, removal of pigments by contact with bleaching clays,  removal of odours by high-vacuum distillation.

corn germ oil extraction plant

Corn oil is extracted from the germ of corn. Its main use in cooking, where its high smoke point makes refined corn oil a valuable frying oil.

The germ, which constitutes 8-14% of the total weight of the corn grain, includes 84-86% of the total oil content of the corn. The germ is the primary product for making corn oil and one of the important ingredients of animal fodder.

The germ oil contains unsaturated fatty acids (linoleic 56%, oleic 30%, linolenic 0.7%) and 14% of saturated fatty acids. Its protein part includes about 37% globulins, 51% glutelin, 5% zein, and 7% of non-soluble oils. Maize germ also carries a wide range of amino acids and is rich in vitamin Е (tocopherol), beta-sitostiron and phytin.

Cornoil refining process contains corn crude oil, degumming, alkali refining, washing, drying, alkali refining oil, declorizing, filter, decolorizing oil, crystallization, maturing, dewaxing oil, deodor, cooling.

The main equipment are disc oil separator, decolorizing tower, filter, crystallization tank, maturing tank, deodor tower. In the deodor section, the temperature in the tower is need to controlled about 230 centigrade. The finished oil after deodor section must be cooled, avoid corn oil color reversion. In order to improve corn oil yield, low product cost, the alkali oil acid value must be control a certain range. The filter aid adopt diatomite can improve dewax effect.

Vegetable oil refining equipments

Deacidification tower is an important oil refining equipment, its main function is to remove free fatty acid of crude oil. Upper is packing layer, the lower plate is a layer structure. The tower is the most suitable for physical refining of soft modular tower; spray steam mode or using the bottom of the bubble Montmartre pump, direct steam and oil more evenly mixed, direct steam higher utilization, lower deodorizing process the formation of trans fatty acids.

Crystallization tank maturing tank mainly used to oil dewax section. Main feature is convenient operation and maintenance, easy clean, stable operation, low energy consumption.

Deodorization tower is mainly used for removing the small molecule odor organic matter in oil, need be equipped with vacuum distillate ,capture, high temperature heat exchange system, etc.

Deodorization tower main technical characteristics : deodorization tower is main equipment of deodorization section, divided into the tower type, packing type, combined type, etc, all stainless steel is fully closed structure, long service life, less steam consumption, deodorization time is short, oil quality is good.

Decolorizing tower,major equipment of decolorization, full removal of oil pigment, reduce oil color.
