To ensure the extraction of high-quality walnut oil, the walnut oil production equipment needs to pay attention to several factors, such as cleaning and crushing, shelling, controlling moisture and temperature, pressing, refining, and other steps. First, the walnuts need to be pre-processed by cleaning them thoroughly and then crushing them into small pieces or particles. Next, the shelling process is carried out to obtain the walnut kernels. Then, the moisture and temperature of the walnut kernels are controlled through roasting, which facilitates better oil pressing. After that, an oil press machine is used to extract the crude oil, which is further refined using refining equipment to remove impurities, acids, colors, odors, and wax, ensuring that the walnut oil is of good quality and safe for consumption.
