Frying line (or frying production line) refers to an automated production system used for continuous batch frying of food. It typically consists of feeding, frying, de-oiling, cooling, and conveying stages. Frying lines are widely used in processing potato chips, chicken nuggets, spring rolls, puffed snacks, and other food products. The core equipment is a continuous fryer, which controls oil temperature, frying time, and de-oiling performance to ensure consistent product quality.
