The food delivered into the frying chamber is fried in the frying box and finally discharged through the discharge pipe, thereby completing the automatic loading, frying and automatic unloading operations of the food.

[0017] The beneficial effects of the present invention are: 1. When the present invention is working, it can automatically complete the feeding, frying, oil draining and cooling, and centralized unloading operations of fried food. By realizing the above functions, the automation degree of the production line is effectively improved.
