Peanut Oil Production Line

Huatai Group focuses on the overall integration and optimization of the peanut oil production line. From the input of raw materials to the output of finished peanut oil. Each device is seamlessly connected. Through advanced automatic control systems, the temperature, pressure, flow, and other parameters in the production process are monitored and precisely controlled in real time.

We can ensure the efficient and stable operation of the production line, greatly improving production efficiency and reducing labor costs and energy consumption.

Huatai Group develop a new oil extraction technology can greatly increase the oil yield of peanuts while ensuring the quality and flavor of the oil. The unique filtering and refining technology can further remove impurities and undesirable ingredients in the oil, making it meet the highest international standards.

The Process of Peanut Pretreatment

The peanut pretreatment processes include cleaning and separating of hull & kernels. According to pressing temperature, there are two groundnut oil pressing technologies: hot pressing and cold pressing.

  • Peanut Cleaning

    Impurity removal: Remove stones, straw, metal impurities, etc., from peanuts through vibrating screens and magnetic separators.

    Color sorting: Moldy, discolored or damaged peanut kernels are removed using photoelectric sorting technology.

  • Peanut Shelling and
    Separating of Hull & Kernels

    Sheller: Removes peanut shells through mechanical friction or centrifugal force, retaining peanut kernels (kernel yield is about 70-75%).

    Kernel-shell separation: Wind selection or screening technology completely separates the shell from the kernel to reduce subsequent pressing interference.

  • Peanut Crushing &
    Softening, Flaking, Cooking

    Crushing: Crush the peanut kernels into small particles (2-4mm) to increase the surface area for subsequent pressing efficiency.

    Softening: soften the cell structure and reduce the pressing resistance through steam heating or moisture adjustment (moisture content of 5-8%).

    High-temperature steaming and frying: In a rotary steaming and frying pan, the peanut kernels are heated to 110-130°C, and the moisture content is controlled (3-5%).

    Function: destroy the cell wall and promote the release of oil; adjust the degree of protein denaturation (affecting the texture of the pressed cake).

PRESSING PROCESS

Peanut Oil Pressing Process

Pre-pressing: The peanut kernels steamed and fried at high temperature are directly put into the screw press, and the oil is squeezed out by mechanical pressure (pressure up to 100-200MPa).

  • High oil yield (cold pressing about 40-45%, hot pressing can reach 45-50%).
  • The oil cake has low residual oil (about 6-8%), which is suitable for further oil extraction by subsequent leaching method.
  • The oil product is darker in color and has a strong flavor (suitable for traditional cooking).

Cold pressing process (low temperature physical pressing)

Oil yield (about 35-40%), but retain more natural flavors and nutrients (such as vitamin E, sterols).

The oil product is light in color and has a high smoke point, which is suitable for low-temperature cooking or health products.

Peanut Oil Refining Process

After a long period of precipitation, the crude peanut oil can be filtered by a filter and sent to a refining plant. The pressed cake can be crushed and sent to an extraction plant for secondary extraction, extraction oil is refined and sold as ordinary oil.

Refining is to remove impurities, odors, and pigments from groundnut oil and improve the quality and taste of the oil. The refining process mainly includes steps such as degumming, deacidification, decolorization, and deodorization.

Groundnut oil refining process

Degumming: Add hot water or phosphoric acid to remove phospholipids and soluble impurities.

Deacidification: Alkali refining method to neutralize free fatty acids (reduce acid value).

Decolorization: White clay or activated carbon adsorbs pigments (such as chlorophyll, carotenoids).

Deodorization: High-temperature vacuum distillation to remove odor substances (such as aldehydes and ketone compounds).
