AI Technical Summary

Technical Problem

Traditional gas-fired fryers suffer from slow oil temperature rise, high energy consumption, and uneven oil temperature distribution due to single-point heating, which affects processing efficiency and product quality.

Method used

A dual heating method is adopted, which heats the bottom of the oil cylinder through the burner and uses the high-temperature exhaust gas in the vent pipe to assist in heating the oil. Combined with the gas supply hood and cylindrical vent pipe, the heat utilization rate and uniformity are improved.

Benefits of technology

Accelerate the oil temperature rise, improve processing efficiency, ensure consistent frying of food, reduce gas consumption, and lower operating costs.
