Spiral oil press for processing corn germ oil

Processing corn germ oil

Corn oilis yelow,transparent oil with has a aint smel and faint taste. ti is an easly absorbed vegetable olwhichisnot areasy.ti is qute stable when frying at a hich temperature，and can kep the color and favor ofveetables and fds without losing the nutritive value. Blended wih a cold dish，it couid lend a faint senttothe dish, Com cerm also has a long shelf life.

Corn Oil Has a High Content of Unsaturated Fatty Acid

Corn oilis a rich source of unsaturated fatty acid,especially,linoleic acid. While it doesn’t contain cholesterol itself. it can also lower thecholesterol in the blood, thus reducing the hardening inluence on the blood vesel. Long-term consumption can beneft patients suffering fromhypertension, adiposis, hyperlipidemia, diabetes, coronary heart disease, etc.

How to Make Corn Oil?

corn ol is also called corn germ ol. lt is made from corn germ, which is at the base of the corn kernel. The most fat of corn kerelis in the cor germCor germ can be pressedby inlegraled screw oil press This machine is one ofthe advanced oil presses.t can squeeze and flter ol at the same time with high oilyield and laroecapacity, labor-saving and energy-saving. The temperature is controlled automatically.

smaller type screw oll press can also be used to press corn germ. it is with small sze thatcoveria ltte sace.Screw oil presses are more suitable formedium-sized and small-sized grain and cooking oil processing factories or specialized households. The capacity ranges from 1-20 ton per day.After pressed by screw oil press, we get crude oil, which contains a large number of impurities, and it will become turbid at low temperature,not edibleAter the relning process includina deoumming, neutralization, bleaching and deodorzation, we getthe reined corn oil with low turbidity point. lowmellina point and can be stored in a stable state, Further processed corn oi can be used in humanized milk powder health food. and medicine forthildren and the elder,as wellas high grade cosmelic. The by-product ol cake can be used for making a nutritional supplement of various foods or addedin animal feeds Corn oilcan also be used as feedstock for biodiesel. rubber substilutes, rust preventalives, inks soaps textiles, and insecticides etc.

The spiral oil press can achieve high oil yield and stable production efficiency in the corn oil pressing process through reasonable pressure control, temperature regulation, and feed management. At the same time, the pressed oil residue and cake slices also need to be properly processed to ensure the quality and safety of the final product.

Corn hydraulic pressing production line

Before pressing, corn germ needs to undergo appropriate drying treatment to ensure its moisture content is below 4%, and the pressing temperature should be controlled above 100 ℃ to facilitate oil separation. During the pressing process, the temperature of the embryo should be maintained at 30-40 ℃, and the initial feed should be small. After the press is running normally, the feed should be evenly distributed to ensure the stability of the oil and cake discharge. During pressing, the embryo is pressed in the chamber for 2.5 minutes, and the thickness of the cake is 5-6 millimeters.

In the process of extracting corn oil, the first step is to extract the corn germ, which is a crucial step in the entire pressing process. Corn germ is usually separated by dry dehulling or wet milling to ensure the physical properties of the germ and endosperm are different, thereby flattening and sieving the germ. The extracted corn germ needs to go through steps such as moistening, peeling, crushing, and rolling to ensure that its moisture content is appropriate for subsequent pressing.

What are the specific requirements for the moisturizing and drying steps of corn germ before pressing?

The moistening and drying steps of corn germ before pressing are key steps to ensure the pressing effect and oil yield. The following are specific requirements:

Moisturizing treatment

• Objective: To increase the toughness and elasticity of corn husks and germ by making them absorb water, facilitating subsequent peeling and crushing operations, and improving the extraction rate and purity of germ.
• Operation method: The soaking time is generally 5-8 minutes, and the soaking temperature is controlled between 60~90 ℃ to ensure that the corn fully absorbs water but does not soften excessively.
• Effect: After moistening, the moisture content of corn will increase, making it easier for subsequent peeling and crushing operations, while improving the separation efficiency of germ.

drying process

• Objective: To reduce the moisture content of corn germ to meet the requirements of pressing process, prevent oil spoilage and rancidity, and improve pressing efficiency.
• Moisture requirement: The moisture content of dried corn germ should be controlled below 4% to ensure the oil separation effect during the pressing process.
• Drying methods: Common drying methods include fire drying, steaming and frying to remove water, and mechanical drying. Usually, a three-stage drying process is used, with the first stage drying to 35% moisture, the second stage drying to 10%, and the third stage drying to below 4%.
• Drying effect: The dried corn germ has a high oil content (45-50%) and a uniform texture, making it easy for subsequent embryo rolling, steaming, frying, and pressing operations.

Moisturizing and drying are important pretreatment steps before pressing corn germ, which optimize the physical and chemical properties of the germ by increasing and decreasing moisture, respectively, thereby improving pressing efficiency and oil yield.

Corn Oil Contains Rich Vitamin A, D, and E

• The vitamin A in corn oil can promote the growth of epithelial tissue and reduce the break out of dermatitis.
• The vitamin D in corn oil can promote the absorption of Ca and is of great beneft to the growth of the bones of children.
• The Vitamin E in corn oil is an antioxidant that can obviously prevent and cure xerophthalmus nyctalopia,dermaiis,thrombophlebilis, muscular atrophy, and trophism Encephalomalacia etc. The vitamin E has also an-aoin elect.! can improvethe endurance or exercis and chil. Adding to milk powder, it can help the growth of retina and cerebral cortex of infants.

Corn oil processing equipment can achieve efficient processing of corn germ, from extraction, pressing to refining, with a high degree of automation in the entire process, greatly improving production efficiency and yield per unit time. Choosing reliable corn oil processing equipment can ensure hygienic conditions during the oil extraction process, avoid oil contamination, and ensure the safety and health of the final product. The professionalism and reliability of Zhengzhou Fude Machinery in the field of corn oil processing equipment make it an important reference for oil factories in equipment procurement. By selecting appropriate equipment, enterprises can not only improve production efficiency and product quality, but also achieve a win-win situation of economic benefits and social responsibility.
