Stainless Steel Oil PressBefore oilseeds are pressed, they should undergo pre-treatment, as the quality of pre-treatment directly affects the oil extraction results. Good pre-treatment can achieve:a. Increased oil yield;b. Higher quality oil and oil cake;c. Improved equipment processing capacity and reduced energy consumption;d. Ensured equipment safety.General oilseed pre-treatment includes:1. Cleaning: Cleaning removes dirt, stones, and metal objects from the oilseeds. Poorly cleaned oilseeds will accelerate parts wear and even damage the oil press, as well as reduce oil yield.2. Shelling and Separation: To fully utilize the oil press’s production capacity and reduce oil loss, shelled oilseeds like peanuts, tung seeds, cottonseeds, and tea seeds should be shelled and separated before pressing. This is an essential step.3. Crushing and flaking: rapeseed and soybeans(cold pressing) can generally be pressed in a whole condition, but crushing and flaking the seeds will improve oil yield. Other oil seeds also perform better when crushed and flaked before pressing.4. Steaming and cooking: the quality of steaming and cooking oilseeds is the key point of increasing oil yield. Steaming and cooking control the moisture content and increase the temperature of oilseeds before pressing. Users can choose suitable steaming and drying equipment to match with the oil press. (Hongyang Company produces the YHCZ series cylindrical cooker, which is available for user selection)

Hydraulic Oil PressXinxiang Hongyang Machinery Co., Ltd. (formerly Xinxiang Hongyang Oil Machinery Factory), located in the National Economic and Technological Development Zone of Xinxiang City, Henan Province, China, is a long-established manufacturer of oil processing equipment. As a member of the China Cereals and Oils Association and the China Feed Industry Association, and a governing unit of the Xinxiang Charity Federation, the company successfully transformed from an old factory in 2004 into a modern oil engineering technology enterprise that integrates product research and development, manufacturing, sales, service, and import and export trade.

Rapeseed oil equipment, also known as rapeseed pressing equipment, is developed and produced by Xinxiang Hongyang Company. Its significance lies in extracting high-nutrient edible oil from rapeseed.Pressing MethodThe pressing method, also known as the "physical pressing method," uses external force to squeeze the oil out of the oilseeds without using other chemical solvents, thus avoiding residual organic solvents in the oil. Xinxiang Hongyang Company's pressing process largely retains the effective components in rapeseed—such as polyunsaturated fatty acids, proteins, dietary fiber, vitamins, and trace elements—which are beneficial to human health and suitable for targeted nutritional supplements.Production ProcessHarvesting and screening rapeseed → Rapeseed → Cleaning impurities → Drying → Roasting → Pressing → Pressed rapeseed crude oil → Coarse filtration → Fine filtration → Rapeseed oilRapeseed oil, commonly known as vegetable oil, also called canola oil or fragrant vegetable oil, is a type of edible oil pressed from rapeseed. The oil is golden yellow or brownish-yellow in color and has a certain pungent odor, known as "green odor" among the people, which is due to the presence of glucosinolates. However, premium varieties of rapeseed do not contain this substance.Rapeseed oil is one of the main edible oils in China, primarily produced in the Yangtze River Basin, and in the southwest and northwest regions, with the highest production in the world. The human body can absorb up to 99% of rapeseed oil. It has the effects of softening blood vessels and delaying aging.Since the raw materials for pressing oil are plant seeds, they generally contain a certain amount of seed phospholipids, which are crucial for the development of blood vessels, nerves, and the brain.Rapeseed oil contains very little or almost no cholesterol, making it a safe choice for those who need to control their cholesterol intake.Rapeseed oil has a particularly high content of erucic acid, and there is still debate on whether it can cause myocardial fat deposition and heart damage. Therefore, patients with coronary heart disease and high blood pressure should consume it with caution.According to traditional Chinese medicine, rapeseed oil is sweet, pungent, and warm in nature. It can moisten dryness, kill parasites, reduce fire, and relieve swelling and toxicity.

Basic Concept of Oil Press1. Compression Curve of the Pressing Chamberin the pressing chamber of Xinxiang Hongyang Brand screw oil press, due to the increasing width of pressing screw threads, the decreasing screw pitch and the thickening spiral diameter, etc, after raw material enters to feeding section, the material is propelled and compressed as the pressing screw rotates. The degree of compression changes as the material moves through the pressing chamber. Depicting the variation in the compression degree of raw material as it was propelled through the pressing chamber into a drawing, which is called compression curve of pressing chamber. The compression curve of pressing chamber runs as Figure 5-1Figure 5-1 Compression Curve of the Pressing ChamberFrom Figure 5-1, it can be seen that the compression process of the material in the pressing chamber is divided into three sections, analyzed as follows:1. Feeding Section: In the feeding section, the material starts to be compressed, expelling air and moisture, undergoing plastic deformation, and beginning to release oil. Therefore, a small amount of oil droplets and bubbles can be seen at the front end of the pressing cage.2. Pressing Section: The space in the pressing chamber in the pressing section decreases rapidly and regularly. The material is subjected to intense pressure, causing the particles to combine and form a continuous porous mass that expels a large amount of oil. During this process, the material also experiences various types of friction while being compressed.Specifically, pressing screw interrupt, pressing chamber’s knife bar, pressing rod edge’s shearing action cause raw material displacement, breakage and mixing, which continually open oil pathway, allowing for rapid and thorough oil extraction3. Cake Forming Section: In the cake forming section, the material has formed into tile-shaped cakes that advance almost as a single unit, resulting in significant axial compression resistance. At this stage, the compressibility of the tile-shaped cakes is minimal, but it is necessary to maintain high pressure to ensure thorough oil drainage. This process should be extended for an appropriate amount of time, and the axial resistance should be reduced (the geometric dimensions of the screw change very little at this point). If the pressure is reduced too early, the hot cake will expand and loosen, reabsorbing oil, which is detrimental to pressing. The discharged cakes generally expand slightly due to elasticity or expansion.2. Compression Ratio and Total Compression Ratio1. Free Volume of the Screw: The free volume of the screw refers to the space volume enclosed by the screw in each lead (pitch) within the pressing chamber.2. Compression Ratio: The compression ratio is the ratio of the free volumes of the screw in two adjacent leads. If the free volumes of the screw in two adjacent leads are Vn and Vn+1, respectively, then the compression ratio is:3. Total Compression Ratio: The total compression ratio is the ratio of the free volume of the first lead where the material enters to the free volume of the lead at the cake discharge end. If the free volume of the first lead is V_in and the free volume of the lead at the cake discharge end is V_out, the total compression ratio ε is:

Vertical Oil Rendering PotRendering method: Typically used in the processing of animal fats, where animal fats are heated at high temperatures to destroy all fat and oxidative enzymes in the tissue. Even with residual solids present after rendering, the fats do not spoil. therefore the rendering method developed by Xinxiang Hongyang Machinery CompanyExtraction process is considered a more advanced processing method in terms of hygiene. However, the temperature during rendering should not be too high, and the duration should not be too long to prevent partial fat decomposition and increase in free fatty acids in the oil. Excessively high temperatures can also cause animal tissues to char, affecting the sensory characteristics of the products.This vertical oil rendering pot is suitable for refining various edible-grade animal fats such as edible lard, edible chicken fat, edible duck fat, and edible beef fat.Extraction ProcessWith the scale of pig farming becoming increasingly large-scale in the market, many large-scale pork processing enterprises have substantial amounts of pig fat that need to be processed and utilized. currently, Xinxiang Hongyang Machinery Co.
