Castor oil has a mild flavor and a light yellow color. It has the characteristics of non-drying, non-volatile, and viscous. Castor oil is widely used in industries such as industry, medicine, and cosmetics. It can be used to produce industrial products such as lubricants, paints, resins, plasticizers, and polyurethanes. It is also used in the production of cosmetics, skin care products, drug excipients, and special chemicals. Compared with other oils, castor oil is less prone to oxidation when not exposed to extremely high temperatures.
As a manufacturer, AGICO Group has helped many domestic and international customers set up oil mill plants. We are happy to provide solutions and oil mill machinery for a castor oil processing plant.
Why invest in castor oil processing plant
High Value
Compared with ordinary vegetable oils, castor oil belongs to industrial special oils. Its product value is high and the profit margin is greater.
Immense Markets
The global castor oil market size reached 812.1 Kilo Tons in 2025. Looking forward, it is expected the market to reach 891.0 Kilo Tons by 2034, exhibiting a growth rate (CAGR) of 1.03% during 2026-2034.
Advanced production technology
AGICO is a professional and experienced manufacturer of castor oil equipment. Our production line and equipment adopt mature and advanced technology, ensuing high output, high automation levels, and guarantee product quality.
Castor oil processing plant process
1.Cleaning
First, remove the outer fruit skin from the castor seeds. After removing the seed shells, the castor seeds are sent to a cleaning machine.
2.Cooking
After cleaning, the seed is sent to a cooking machine to remove water.
3.Drying
Then it should be placed in a oven for further drying for at least seven hours.
4.Pressing
The castor seeds are crushed by a screw pressing machine to obtain oil. The oil extracted after pressing is filtered, and the filtered material is mixed with fresh new seeds for repeated extraction. In this way, a large amount of filtered material is continuously collected and repeatedly combined with new materials in the process cycle. Eventually, the castor cake is discharged from the press.
5.Refining
The extracted oil needs a refining process. The refining process includes steps such as degumming and deacidification to produce pure oil.
Advantages of AGICO castor oil processing plant
Castor seeds have characteristics such as hard shells, high fiber content, and significant variations in oil content. When customers invest in a castor oil processing plant, they usually face many production difficulties.
Difficulty 1. Insufficient adaptability of raw materials
The castor seeds grown in different regions vary in terms of oil content, moisture content, and impurity content. If the design of the equipment does not match the different seeds, resulting in an unstable oil yield rate.
AGICO castor oil processing plant is equipped with professional cleaning, crushing, shell removal, and cooking pre-treatment systems. It can also adjust processing parameters according to different production areas. It can efficiently reduce impurity content, improve pressing performance, and increase raw material utilization rate.
Difficulty 2. Difficult raw material processing
The castor seed has a special structure. If equipment pressure control is unreasonable or the spiral structure design is insufficient, it will lead to insufficient oil extraction. A large amount of oil remains in the cake, increasing raw material loss.
AGICO castor oil processing plant adopts a high-quality stainless steel high-strength screw oil pressing machine and has optimized the pressing chamber. By reasonably controlling pressure, temperature, and the retention time of the materials, the oil in the castor seeds is fully released. This reduces the residual oil in the castor oil cake and maximizes the oil yield.
Difficulty 3.Unstable oil quality
Castor oil is widely used in high-value fields such as chemical engineering, medicine, and cosmetics.and has strict requirements for the purity, color, acid value and impurity content of the oil.
AGICO castor oil processing plant adopts a PLC intelligent temperature control system. It can adjust the cooking and pressing temperature according to production needs, avoiding oxidation or color deepening due to excessive temperature. At the same time, it is equipped with an efficient filtration system to remove impurities. This avoid leading to not suitable for high-value fields.
Castor oil processing plant cost
Castor oil equipment cost

By-products in castor oil production
Castor Cake
The cake residue obtained after pressing castor seeds is rich in protein and organic matter, and is the main by-product in castor oil production. After detoxification treatment, it can be used to produce organic fertilizers, soil conditioners, and biomass resources. Due to the high nitrogen content in the castor cake residue, it can improve soil fertility, increasing agricultural added value.
Castor bean shell
Castor shells and the waste materials generated during the cleaning process can be used as biomass fuel for heating boilers or generating electricity, reducing energy consumption. At the same time, they can be processed into biomass pellet fuel to achieve resource utilization of waste materials.
Refining By-products
The by-products, such as soap residue and fatty acids generated during the refining process of castor oil, can be further processed into industrial fatty acids, surfactants, lubricants, and chemical raw materials, increasing the overall economic benefits of the oil processing chain.
