It can greatly improve the cooking efficiency of dishes while reducing people's workload during the cooking process, freeing people from heavy kitchen labor and having broad application prospects.

[0003] During the stir-frying process, the stir-frying mechanism of the stir-frying machine needs to continuously stir the ingredients in the pot so that the ingredients in the pot are evenly heated and mixed. This is also the main mechanism for whether the stir-frying machine can stir delicious dishes. The stirring device of the stir-frying machine usually includes a main stirring shovel and a side scraper. The stir-frying mechanism usually drives the stir-frying shovel to rotate and revolve simultaneously through a motor to achieve stirring of the ingredients in the pot. The existing stir-frying mechanism of the stir-frying machine has a complex structure, a large volume, and a small stir-frying range. In addition, due to the unreasonable angle setting of the main stirring shovel and the side scraper, the bottom end of the main stirring shovel and the side scraper is not sufficiently fitted to the pot body during the revolution or rotation process. The unbalanced force distribution leads to unstable rotation, which causes the machine to jump, affecting the stir-frying effect of the dishes, and is also easy to cause damage to the stir-frying mechanism after long-term use.
