castor oil processing plant

AGICO Castor oil processing plant

Castor oil is a vegetable oil extracted from the castor seed. Its main ingredient is ricinoleic acid (approximately 80% – 88%). Castor oil can be used internally to treat constipation caused by dry intestines, and externally to alleviate skin inflammation or burns. It is used as a high-temperature lubricant in the industrial field and as a raw material for producing nylon. In the cosmetics industry, it serves as a moisturizer and a solvent for makeup remover, which can repair hair scales and reduce hair breakage. The extraction of castor oil has recently shown significant economic potential. If you plan to establish a castor oil processing plant, AGICO can provide a comprehensive oil extraction plan.

The process of castor oil processing plant

RStep 1 Cleaning: Castor seed removes big impurities with a vibrating screen and magnetic separator. Washing or air-cleaning removes light impurities.
Step 2 Shelling: The outer shell of castor seeds accounts for 20% to 30% of the seed weight. It contains a small amount of oil and also contains toxins (such as ricin). The shell is separated from the kernel by an impact-type shelling machine or grinding machine.
Step 3 Crushing: The castor seed is crushed into small pieces, then it is pressed into thin sheets by a rolling machine （0.2-0.4mm）, broken cellular structure and an increased oil rate.
Step 4 Pressing: Cold press: the temperature is below 60 degrees. It could retain more nutrition, and the oil rate is low. Hot press: After steaming and stir-frying the seeds until they reach a temperature of 100-120℃, the pressing process is carried out. The oil yield can be increased to 40%-45%, but high temperature may affect the quality of the oil.
Step 5 Refining: The extracted oil needs to be refined. Refining involves steps such as degumming and deacidification to produce a pure oil.

the features of castor oil processing equipment

The entire workshop has a high degree, full computer display, and automatic control.
Make full use of the residual heat in the production line to reduce the consumption of steam.
When making the white clay pancakes, a device for capturing odors was designed to eliminate odor pollution during the decolorization process and meet environmental protection requirements.
The vacuum system adopts a frozen vacuum or chilled water vacuum system, which greatly reduces stream consumption and wastewater discharge amount.
It has high yield, excellent performance in various indicators of the oil product, and low consumption, etc.

The advantage of castor oil processing plant

Value-added product

Castor bean meal: The residue after pressing contains 35% - 50% crude protein. After detoxification (through heat treatment or solvent extraction of castor alkaloids), it can be used as organic fertilizer or feed additive.
Castor shell: it could serve as biomass fuel or cellulose raw materials.
Soap residue: it is used for the production of fatty acids or biodiesel

Lower maintenance cost

Suitable and easy-to-operate equipment

the market of castor oil processing plant

The global castor oil market size was valued at $943.65 in 2024 and is anticipated to reach around $1,345.33 by 2034, growing at a CAGR of 3.61% over the forecast period from 2025 to 2034.
Because of the special fatty acid structure, castor oil has an advantage compared with other vegetable oils. The applications of cottonseed oil, coconut oil, soybean oil, corn oil, rapeseed oil, etc. are mostly limited to the food industry. But castor oil is renewable, natural, and has wide applications in terms of physical and chemical properties. So these products serve as raw materials including lubricants, grease chemicals, medicine, cosmetics, pharmaceuticals, bioenergy, and many other fields are preferred. Due to the increasing global recognition of the importance of green chemicals, the market will keep increasing steadily in the coming years.
