The equipment configuration for a copra oil processing plant depends on the chosen processing method-mechanical pressing or solvent extraction-as well as the target production capacity and refining grade. For enterprises intending to invest in coconut oil processing, understanding the core equipment components is the first step toward project implementation. Drawing on the practical project experience of Henan Huatai Cereals & Oils Machinery Co., Ltd., the following outlines the key equipment needed for a complete copra oil processing line.
A complete set of equipment for a copra oil processing plant is typically divided into three main sections: pretreatment, oil extraction (pressing or solvent extraction), and refining. For small-to-medium capacities (e.g., 20 TPD), hydraulic or screw pressing is the mainstream choice; for large-scale production (over 100 TPD), solvent extraction allows for more thorough oil recovery. In a 40 TPD copra pressing and 20 TPD refining project delivered in Indonesia, Henan Huatai optimized the press chamber structure based on the specific characteristics of copra, helping the client increase oil yield and reduce residual oil in the press cake.
1. Copra Pretreatment Section Equipment
Before entering the oil press, copra must undergo processes such as cleaning, crushing, and steaming/roasting; these steps directly impact the oil yield.
Key equipment includes:
Cleaning and crushing equipment: Raw copra may contain impurities and requires magnetic separation and crushing into small particles to facilitate more complete oil release during subsequent pressing or extraction.
Steaming and roasting equipment: Crushed copra usually needs to be steamed and roasted at 70–90°C for 20–30 minutes to soften fibers and adjust moisture content, thereby improving oil yield.
2. Copra Oil Extraction Section Equipment
This is the core stage of the copra oil processing plant, with equipment selection based on capacity and processing method.
1) Screw oil press (suitable for small-to-medium capacities)
The screw oil press uses a continuous screw shaft to push copra into the press chamber, gradually compressing the raw material to extract the oil. For raw materials with high oil content (60%–70%) like copra, a double-pressing process is typically employed to minimize residual oil in the cake. In the 40 TPD copra oil project in Indonesia, Huatai designed a specialized press chamber structure tailored to copra's characteristics to help the client maximize oil yield.
2) Copra Oil Solvent Extraction Equipment (Suitable for Large-Scale Production)
Solvent extraction is the more economical choice for daily processing capacities exceeding 100 tons. This process utilizes organic solvents to extract oil from copra, achieving extremely low residual oil levels in the meal. Key equipment in the extraction section includes:
Continuous Extractor: Ensures thorough contact between copra and the solvent.
DTDC System: Performs desolventizing, drying, and cooling on the wet meal, ensuring the copra meal is safe, non-toxic, and suitable for use as animal feed.
Solvent Recovery System: Recovers solvent through multi-stage evaporation, thereby reducing operating costs.
3. Copra Oil Refining Section Equipment
Crude coconut oil contains free fatty acids, phospholipids, pigments, and odor-causing substances; it requires refining to become a finished product that meets market standards. Huatai's intelligent coconut oil refining process focuses on controlling critical stages such as alkali refining, bleaching, and deodorization. It effectively removes impurities while preserving the coconut oil's natural flavor, ensuring the finished product meets quality requirements for premium edible oils.
Key equipment in the copra oil refining section:
Degumming/Alkali Refining Equipment: Removes phospholipids and free fatty acids.
Bleaching Equipment: Uses activated bleaching earth to adsorb pigments, resulting in clear, bright oil.
Deodorization Equipment: Removes odor-causing substances under high-temperature and high-vacuum conditions to produce colorless, odorless RBD coconut oil.
Filtration and Storage Equipment: Finished oil undergoes precision filtration before being stored in stainless steel tanks.
4. Why Choose Henan Huatai Oil Machinery?
Since its inception in 1988, Henan Huatai Cereals & Oils Machinery Co., Ltd. has accumulated 38+ years of experience in manufacturing grain and oil machinery. It is a national-level "Little Giant" enterprise (recognized for specialization, refinement, uniqueness, and innovation) and is listed on the NEEQ (New Third Board).
