Complete Equipment List for Large-Scale Rapeseed Oil Production Line

图片
Large-scale rapeseed oil pressing production line (suitable for daily production capacity of 50-500 tons/day, meeting large-scale industrial production), is divided into four sections: pretreatment section, oil pressing section, refining section, finished product storage and filling section. The equipment in each section operates linked to ensure the automation and high efficiency of the whole process from rapeseed raw materials to qualified edible oil. The following is a detailed description of each equipment (including function, specification and function, adapting to the needs customers): Pretreatment section Function: removing impurities, optimizing billets, improving efficiency for subsequent pressing and reducing equipment loss. Pretreatment is the basis of large-scale production line, which directly affects the oil output rate and the service life of subsequent equipment. The complete set of equipment according to the process is as follows: 1. Vibrating Cleanin...

Advantages and Disadvantages of Screw Oil Presses

图片
In the edible oil processing sector, screw oil presses have become the preferred equipment for small and medium-sized oil mills due to their high efficiency in continuous operation and broad applicability. Through the rotational advancement of the screw shaft within the pressing chamber, it utilizes progressively increasing pressure and friction-generated heat to rupture oilseed cells and extract lipids.   Combined with vacuum filtration technology, it achieves integrated processing from raw materials to finished oil.   Whether processing common crops like peanuts and rapeseed or premium nuts such as walnuts and flaxseeds, these machines accommodate diverse extraction methods (hot/cold pressing). This flexibility solidifies their significant market position. ​ Advantages   High and Stable Oil Yield: Compared to older oil extraction equipment , the screw oil press employs a multi-stage progressive pressure design.   Pressure within the chamber gradually increases, all...

How To Choose The Right Oil Production Line

图片
The growth and maturity of different oils are not the same, according to the season and the most suitable maturity of oil, most oil extraction plants do not produce only one kind of oil. Therefore, in the purchase of oil press, a set of versatile oil press production line is worthy of the oil plant owner's love. According to the characteristics of oil crops and oil content are distinguished: Oil with low oil content and similar texture: such as soybeans and peanuts, the oil content of soybeans is generally 18%-22%, and the oil content of peanuts is 40%-50%, although the oil content of peanuts is relatively high, but both are more common oil crops, and the texture is relatively moderate. They can all be pre-treated (such as cleaning, peeling, rolling, etc.) and pressed by the same set of oil pressing equipment. Pretreatment equipment such as cleaning screens can remove impurities, a sheller (peanuts need to be shelled, soybeans may also need to be treated in some cases), a billet mi...

Production Process of Flaxseed Oil

图片
The production process of linseed oil mainly includes pressing method and special solvent extraction method. The pressing method involves applying pressure to the raw material to extract the oil from the oilseeds. The main advantage of this technology is that it does not require the use of chemical solvents and can produce a more natural product. All polyunsaturated fatty acids, proteins, food fiber, vitamins, trace elements and other useful substances are stored in flaxseed oil. 1. Oil Pressing method: Oil screening: The harvest of flax seed is cleaned, and the raw material is screened with a vibrating screen to remove the debris, so that the impurity rate is less than 0.5%. This step is to ensure the smooth progress of the subsequent pressing process and the quality of the oil. Roasting (hot pressing required) : If the hot pressing method is used, the flaxseed should be baked and fried, and the temperature and moisture of the pan should be strictly controlled. Roasting can improve th...

Edible Oil Dewaxing Equipment: In-Depth Study Of Its Composition And Principle

图片
First, edible oil dewaxing equipment overview. Edible oil dewaxing equipment plays a vital role in the process of edible oil refining. Its main function is to remove the wax components in edible oil and improve the quality and stability of edible oil. The wax in edible oil will affect the transparency, taste, digestion and absorption rate of oil, and reduce the edible quality and nutritional value of edible oil. By dewaxing treatment, edible oil can maintain good fluidity in low temperature environment to avoid turbidity and solidification phenomenon. Dewaxing is an indispensable step in the refining of edible oil. Only after dewaxing treatment, edible oil can reach higher quality standards, such as first and second class oil standards. Different kinds of edible oil, such as sunflower oil, rice bran oil, corn oil, etc., have different wax content, and the demand for dewaxing equipment and process requirements are also different. To sum up, edible oil dewaxing equipm...

Working Principle Of Oil Press Equipment

图片
  1. Hydraulic Oil Press Machine The hydraulic oil press mainly uses the hydraulic principle to inject high pressure liquid into the oil press room, so that the oil crops such as peanuts are squeezed out from the cells under the action of high pressure liquid. The hydraulic oil press is simple to operate, but its adaptability to oil is poor. For oil crops with low oil content or too thick hard shell, the oil pressing effect of the hydraulic oil press will be affected to a certain extent. 2. Screw Oil Press Machine The screw oil press mainly uses the principle of screw extrusion, through the extrusion of the rotating screw shaft and the inner wall of the press chamber, the oil crop is broken under high temperature and high pressure, and the oil is squeezed out from the cell. The screw oil press can work continuously, with high efficiency, strong adaptability, and higher oil yield than the hydraulic oil press. 3. Oil Extraction Method Oil extraction method m...

Analysis Of The Function Of Soybean Puffing Machine

图片
What is the role of Soybean puffing machine? As one of the important equipment of oil extraction plant. The main function of Soybean puffing machine is to treat oil by high temperature and high pressure , so that it reaches high temperature and high pressure state in an instant, and then produce swelling effect in the process of decompression, thus changing the physical and chemical structure of raw materials. Second, what is the processing process of Soybean puffing machine? In the processing process of Soybean puffing machine , the oil will be heated to a certain temperature, and then after a moment of high pressure treatment, so that the starch particles containing water inside will quickly form bubbles in the process of high temperature and high pressure and pressure reduction, resulting in puffing effect . The expanded oil is larger in volume, lighter in weight, better in taste, easy to digest and absorb, and can also strengthen the nutrients of the oil, such as dietary fiber and...
