Applications and industries for vegetable oil
The production process of vegetable oil is generally: select oil seeds, sunflower, soybeans, cottonseeds, peanuts, rapeseeds or other types of seeds, pretreat and press them to make crude oil, and finally refine them into refined oil.

Dingsheng Machine provides solutions for the entire refinery edible oil plant, covering the entire process line, the main equipment includes pretreatment equipment, oil pressing equipment, solvent extraction equipment, refining equipment, decolorization equipment, deodorization equipment, filtration equipment and filling equipment.

Technology Process
Solutions for vegetable oil processing

1, Oilseeds Pretreatment Equipment
Pretreatment is the first step in the process of extraction oil from oilseeds. Before oil extraction, the raw materials need to be cleaned, shelled, crushed, puffed, cooked and pressed to improve the structure of the oil plant for better oil extraction during the production process.
Dingsheng Machine offer professional pretreatment equipment, including shelling machines, steaming pans, vibrating cleaning screens, stone removers, crushers, flaking machines, and extruders, etc. The pretreatment part of the production line will be designed according to the type and features of the oil.

2, Oil Extraction Equipment
There are two types of common oil extraction processes: pressing and leaching. The oil extracted by the pressing process is of high quality and can maintain its own flavor and nutrition, but the residual oil rate of the pressing machine is high, which affects the yield of oil and the quality of the cake. For oils with low oil content, the leaching process is more suitable.

The leaching extraction process is to fully contact the pretreated oil with the solvent in the extraction equipment, and extract the oil from the oil cake. Dingsheng Machine provides solvent extraction technology and equipment with higher output, oil yield, higher economic efficiency, safety and ease of operation.

3, Crude Oil Refining Equipment
The oil obtained by pressing or solvent leaching is named crude oil. Crude oil contains various impurities such as phospholipids, proteins, water, free fatty acids (FFA), pigments, waxes and harmful substances. In order to ensure the quality of edible oil, the oil plant needs to refine the oil through refining equipment to remove these impurities and improve flavor, smell, color and stability.

Crude oil refining process includes degumming, deacidification, dehydration, decolorization, deodorization and dewaxing, etc. Dingsheng Machine offers two types of refining processes: chemical and physical refining. The main difference between the two refining processes is how the FFA is removed.
Chemical refining removes free fatty acids during neutralization, while physical refining removes free fatty acids during deodorization. Chemical refining removes phospholipids (gums) in two steps (degumming and neutralization) or in a single process (neutralization).

4, Filling Workshop Equipment
Qualified refined oil can be sold as self-owned brand edible oil after filling, sealing, coding, and labeling. Before selling, the acid value, peroxide value, moisture, aflatoxin, smell, taste, color, etc. of the oil should be checked to see if they meet the edible oil standards. The unqualified oil should be reprocessed and sold after being qualified.

Dingsheng Machine provide the complete sets of automatic filling production line equipment that can achieve filling of different volumes, 1liter, 2 liters, 3liters and 5liters of edible oil. A high-precision filling production line, including automatic bottle blowing machine, automatic filling machine, conveyor belt, stainless steel inspection light box, automatic labeling machine, laser engraving machine, automatic capping machine, and carton sealing machine.

Benefits

Benefits of our professional solutions for vegetable oil processing equipment

The complete set of pretreatment equipment is full continuously and mechanized operation, ensure advanced process indicators, while reduces equipment investment, such as land cost, operating and maintenance costs.
The leaching workshop adopts the international level leaching system and low temperature desolventizing machine, achieve higher mixed oil concentration and lower residual oil. Reduce the amount of solvent circulation, energy and dissolution consumption, thus ensuring the lowest level of residual oil and dissolution consumption.
The fully closed operation system of the leaching workshop, the full negative pressure evaporation avoids oil oxidation; the separation of crude oil and solvent can be realized at a lower temperature condition, which ensures the quality of leaching crude oil, improves the refining rate and significantly reduces energy consumption.
The advanced physical refining process reduces the loss of refining oil and improves the oil quality. The by-products – fatty acids can be directly obtained, helping factories realize the economic benefits of sustainable development. There is no waste water pollution during the process, while meeting the environmental and health requirements.
The edible oil filling production line adopts PLC control system, which has quick running speed and stable performance, and can realize flexible manual operation and automatic operation.
