The oil palm is truly a “golden crop” bestowed upon humanity by nature. As the most economically valuable oil-producing plant in the world, it is widely cultivated in tropical Africa, Latin America, and Southeast Asia, nourishing hundreds of millions of people. To efficiently and stably extract high-quality oil from palm fruits, advanced and reliable processing equipment is essential.

Huatai Intelligent Equipment Group – a NEEQ-listed enterprise, a national-level green factory, and a national-level “Specialized, Sophisticated, and Innovative” Little Giant enterprise – is a professional grain and oil machinery manufacturer with 38 years of experience. We provide turnkey palm oil mill solutions from factory layout design and equipment manufacturing to on-site commissioning and installation.

 I. Full Range of Capacities for Different Scales

Whether you are a start-up or a large oil and fat group, Huatai can match you with the ideal capacity solution:

– Small production line: from 3 tons per hour

– Large plant: up to 120 tons per hour

From single machines to complete plants, Huatai provides a full range of palm oil processing equipment to meet different investment scales and production requirements.

 II. [Pressing Process] From Fresh Fruit Bunches to Crude Oil

 Step 1: Raw Material Receiving

Palm fruit bunches are unloaded, cleaned, and temporarily stored through a fully hydraulic unloading platform. The platform uses segmented hydraulic control for smooth and efficient unloading, serving as the starting point of the entire palm oil production line.

 Step 2: Sterilization

High-temperature steam is used for sterilization treatment of the fruit bunches. This critical step effectively inactivates enzyme activity, prevents oil rancidity, and ensures the excellent quality of crude oil. Huatai’s sterilizer tanks (vertical or horizontal) are equipped with automatic steam control systems to ensure uniform heat distribution.

 Step 3: Threshing

After sterilization, the fruit bunches are fed into a thresher via a bucket elevator, where strong vibration perfectly separates palm fruits from empty fruit bunches. The empty bunches can be recycled as fertilizer or biomass fuel.

 Step 4: Oil Pressing

The fruit is cooked at high temperature to disrupt cell structures, and then the palm fruit press machine squeezes out the oil-rich crude oil. Huatai’s patented twin-screw press features counter-rotating screw design to maximize oil recovery.

 Step 5: Crude Oil Clarification

The press liquor enters the clarification section for sedimentation and separation, and the purified crude oil is transferred to storage tanks for temporary holding. Huatai provides an integrated clarification station equipped with vibrating screens, heating units, and centrifugal separators.

 Step 6: Palm Kernel Recovery

The press cake (a mixture of fiber and palm nuts) enters the fiber separation system. The separated palm kernels are sent to dedicated storage bins for subsequent palm kernel oil extraction. This step allows the mill to obtain two oils from the same batch of fresh fruit bunches, significantly increasing economic returns.

 III. [Refining Process] From Crude Oil to High-Quality Edible Oil

Freshly pressed crude oil contains impurities and requires further refining. Huatai offers three refining solutions:

Solution	Daily Capacity	Suitable Scenario
Batch refining	1-20 TPD	Small production lines
Semi-continuous refining	20-50 TPD	Medium to large production lines
Full-continuous refining	50-600 TPD	Large oil mills

The four core refining steps:

1. Degumming/Deacidification: Uses washing methods to effectively separate soapstock from the oil mixture, preparing for subsequent processes. Core equipment includes degumming tanks, alkali refining reactors, and centrifugal soap separators.

2. Bleaching (Decolorization): Removes pigments, residual soap, and metal ions from palm oil to improve oil color. Uses activated clay adsorption, equipped with bleaching towers and leaf filters.

3. Deodorization: A critical quality enhancement step that uses high-temperature, high-vacuum steam stripping to remove off-odors, producing edible oil with a pure flavor. Core equipment includes deodorization towers and vacuum systems.

Choosing a complete set of palm oil refining equipment is key to ensuring stable finished oil quality that meets international standards.

 IV. [Fractionation Process] The Key to Maximizing Value

Palm oil has unique multi-melting-point characteristics. Through fractionation technology, refined oil can be separated into products with different melting points (such as olein, mid-fraction, and stearin), greatly enhancing economic value.

Huatai fractionation line capacity: 1-500 TPD

Three main steps:

1. Heating: Heats refined oil to approximately 60°C to fully liquefy the oil

2. Cooling crystallization: Precisely controlled cooling causes high-melting-point solid oils to crystallize and precipitate

3. Membrane filtration: Uses advanced membrane filters to efficiently separate solid and liquid fractions

Huatai advantage: Advanced crystallization equipment and filtration equipment, combined with precise temperature automatic control software, ensure stable and reliable fractionation results. Palm oil fractionation equipment is core machinery for deep processing of palm oil and enhancing product added value.

 V. [Palm Kernel Oil Production] Processing the Hard Nuts

Palm nut shells are extremely hard. If pressed directly without separation, they would cause severe equipment wear. Huatai provides specialized palm kernel cracker and separator to efficiently crush and separate kernels from shells.

The complete palm kernel oil pressing process includes:

Cleaning screen → Destoner → Magnetic separator → Cracker → Kernel-shell separator → Dryer → Oil press → Crude oil filter

This complete set of palm kernel oil pressing equipment can efficiently process hard palm nuts, extracting high-value palm kernel oil and creating a second profit source for the mill.
