oil and water mixing fryer: this type of frying equipment. Because the specific gravity of water and oil is different, the water is below, the oil is fried in the upper layer, and the residue is directly deposited in the water. The oil does not emit black smoke, which greatly prolongs the life cycle of the oil and greatly reduces the cost. The oil temperature is precisely controlled, thus ensuring the quality and taste of the potato chips. After the work is finished, the water is released and the residue will flow out along with the water.
