Mechanical mesh belt oil filter is one of the important auxiliary equipment in the production process of fried food, which can work synchronously with the frying machine. This machine uses physical methods to effectively filter out particulate impurities, carbonization, high molecular weight polymers, and other harmful substances generated during the high-temperature frying process of food, improving the frying environment of food, suppressing the increase of acid value and oxidation value, increasing the utilization rate of food oil, reducing enterprise costs, and improving enterprise efficiency and product quality.
