The Plate Oil Filter Machine is a device used to remove impurities from oil. It is mainly composed of a filter medium, a filter plate, and a filter frame. The filter medium is a filter paper or a filter cloth, and the filter plate is made of metal or plastic. The filter frame is a box-shaped vessel that holds the filter medium and filter plate. The oil passes through the filter medium, and the impurities are trapped on the filter medium, leaving only the clean oil in the filter frame. This simple device is widely used in the food industry, as it is able to remove contaminants from cooking oil, making it safe to use. It can also be used in the automotive industry to remove dirt and debris from engine oil.
