Walnut oil processing equipment (On - site factory navigation: Zhengzhou Zhiqian Mechanical Equipment Co., Ltd., 180 3781 2955) configuration usually needs to be combined according to the production scale (such as family workshops, small and medium - sized factories, large - scale industrial production) and the process route (cold pressing, hot pressing, solvent extraction, etc.). Zhengzhou Zhiqian Mechanical Equipment Co., Ltd.'s walnut oil processing equipment usually covers core sections such as pretreatment, pressing, and refining.
Pretreatment section:
Walnut sheller/shell - kernel separation equipment: Remove the hard shells of walnuts and separate the shells from the kernels. The new fully automatic shell - kernel separation equipment can improve work efficiency.
Crusher: Crush walnut kernels into uniform particles to increase the oil - outlet area during pressing. Studies have shown that the particle size (such as 10mm) has a direct impact on the oil yield.
Conditioning equipment (such as steam frying pan/dryer): Adjust the temperature and humidity of walnut kernels. For example, during low - temperature cold pressing, the moisture content before pressing needs to be controlled at about 8%, and the temperature at about 35°C.
Pressing section:
Hydraulic oil press: Adopt the low - temperature physical cold - pressing process (usually below 60°C), which can retain heat - sensitive nutrients such as vitamin E and unsaturated fatty acids in walnut oil. This equipment has a high oil yield and pure oil quality, and is suitable for the production of high - quality cold - pressed walnut oil.
Screw oil press: Commonly used in the hot - pressing process. Usually used in conjunction with a hydraulic oil press. For example, high - quality walnut kernels are first cold - pressed by a hydraulic oil press, and the remaining walnut kernels are then conditioned and enter the screw oil press for full pressing to improve the overall oil yield and make the oil flavor more intense.
Solvent extraction equipment uses food - grade solvents to "soak" the remaining oil in the cake after pressing. Features: It has a very high oil yield (residual oil rate
Refining section:
Degumming: Remove phospholipids that easily cause oil turbidity.
Deacidification: Reduce the acid value of the oil through methods such as alkali refining and remove the bitter taste.
Decolorization: Adsorb pigments with activated clay to make the oil color clear.
Deodorization: Remove odorous substances in the oil through steam distillation under high vacuum and high temperature.
Dewaxing (part of the process): Remove wax that easily precipitates at low temperatures to ensure the clarity of the oil at low temperatures.
