The oil press can process various oil crops, seeds, nuts, and grains. The oil content, texture, and pressing requirements of different raw materials are different, and the suitable oil pressing machines and operating methods also vary. This article summarizes the mainstream oil pressing materials on the market and attaches corresponding equipment usage points.
peanut
Oil content: 40% -50%. Features: Soft texture, high oil yield, suitable for both cold and hot pressing, with a stronger aroma of hot pressed peanut oil.
Equipment adaptation: Suitable for household, commercial, and industrial oil presses, with simple pre-treatment.
rapeseed
Oil content: 35% -42%. Characteristics: Fine particles, hard texture, hot pressing is commonly used in the industry, resulting in better oil quality and oil extraction effect.
Equipment adaptation: Fully automatic spiral oil press is preferred, and it is recommended to use a dedicated feeding device for large-scale production.
sesame
Oil content: 45% -55%. Features: Extremely high oil content, rich oil aroma, mainly using cold pressing technology.
Equipment adaptation: Small and medium-sized oil presses have good adaptability, and it is recommended to screen before pressing to prevent material blockage.
soybean
Oil content: 16% -22%. Characteristics: Conventional oilseeds have low oil content and high protein content, and are mostly used for large-scale industrial oil extraction.
Equipment adaptation: We specialize in large-scale industrial oil pressing equipment, often used in conjunction with hot pressing and leaching processes.
sunflower seeds
Oil content: 40% -48%. Features: The shell is light and thin, the oil taste is light, and it can be pressed cold or hot.
Equipment adaptation: The vast majority of spiral oil presses are universal, and early hulling can improve the purity of the oil.
cottonseed
Oil content: 18% -25%. Characteristics: Strict pre-treatment is required to remove harmful substances, mainly through industrial scale processing.
Equipment adaptation: Professional industrial oil pressing production line, not suitable for household or small equipment.
walnut
Oil content: 55% -65%. Features: High oil nut category, walnut oil has high nutritional value, and is often cold pressed to lock in nutrients.
Equipment adaptation: High end commercial oil presses require the raw materials to be shelled and crushed first.
flaxseed
Oil content: 38% -45%. Features: Rich in linolenic acid, the standard process is cold pressing, and the effective ingredients are maximally retained.
Equipment adaptation: Cold press type oil presses are preferred, and high-temperature pressing is prohibited.
Perilla seeds
Oil content: 40% -50%. Characteristics: With outstanding nutritional value and a focus on the healthy edible oil market, cold pressing technology must be used.
Equipment adaptation: Small commercial cold press oil presses are preferred.
Palm kernels
Oil content: 48% -52%. Characteristics: Widely used in the food and daily chemical industries, with a high demand for industrial processing.
Equipment adaptation: Large integrated oil pressing production line.
summary
The oil content and processing requirements of different oil raw materials vary significantly. When choosing an oil press, priority should be given to determining the main processing materials: household preferred peanuts and sesame; Small workshops are suitable for rapeseed and sunflower seeds; Large factories are suitable for soybeans, cottonseeds, palm kernels, etc. Accurate matching of raw materials and equipment is necessary to ensure oil efficiency and extend the service life of equipment.
