Preferably, a pot cover is arranged at the pot opening of the roller pot to reduce heat loss.

The working principle of the electromagnetic heating roller cooker of the embodiment of the utility model is as follows:

When high-frequency current generated by the electromagnetic heating power supply 11 flows through the electromagnetic heating coil 13, eddy currents are induced in the wall of the roller pan 3, the eddy currents enable the roller pan 3 to generate heat, and materials in the roller pan 3 are heated; in the frying process, the roller pan 3 rotates, the diameter of the middle part of the roller pan is large, the diameter of the middle part of the roller pan is reduced towards the direction of the pan opening and the pan bottom, the material is fried in the middle part of the roller pan 3, the electromagnetic heating coil 13 mainly heats the middle part of the roller pan 3, the thickness of the material in the middle part is large, the heating power density is correspondingly large, so that the heating is uniform, the firepower is concentrated, and the quick frying is facilitated; the temperature near the contact line between the material and the pan wall of the roller pan 3 is low, the material is not easy to be burnt, and the moisture in the material can not be vaporized and exploded drastically to splash oil out of the pan; after the pot is washed, the water attached to the wall of the pot is relatively less because the inner surface area is relatively smaller, and the pot frying time is short when the pot is fried again.

The diameter of the middle part of the roller pot is large, the diameters of the two ends of the roller pot are gradually reduced, and the materials stay in the middle part for stir-frying. Because the electromagnetic heating coil is formed by winding the lead back and forth, the lead passes through the middle part twice and only passes through two sides once respectively, obviously, the power density of the middle part is large, the power density of the two sides is small, and the power distribution is particularly suitable for Chinese food cooking. Therefore, the material is concentrated in firepower when being fried in the middle part of the roller pot, and the effect is better.

The stirring shaft 8 drives the stirring blade 1 to rotate in the roller pan 3, and the stirring blade 1 has the function of scattering food and avoiding food agglomerating; the roller rotating system drives the roller pot 3 to rotate, so that the food is stir-fried; the roller turnover frame 12 drives the roller pot 3 to turn back and forth, which is convenient for stir-frying and feeding and discharging. The fan cooling 14 cools the electromagnetic heating coil 13.

Example 2

Fig. 3 shows another embodiment of the present utility model, which is different from embodiment 1 in that the longitudinal wall of the drum pot is arc-shaped, the middle diameter is large, the diameters of the two ends are gradually reduced, and the drum pot is similar to olive shape and is also suitable for Chinese meal frying. During stir-frying, the materials are concentrated in the middle, the heating power is high, the thickness of the materials is also high, the firepower is concentrated, and the stir-frying is facilitated. Meanwhile, the surface area of the inner cylinder is reduced, and after the pot is washed, the attached water is less, and the pot is quickly cooked. In the frying process, the temperature is low near the contact line between the material and the pan wall of the roller pan 3, the material is not easy to be burnt, and the moisture in the material can not be vaporized and exploded violently to splash the oil out of the pan.

The utility model also has other variants, such as a cover arranged at the opening of the roller pan to reduce heat loss.

In order to achieve the purpose of rapid heat dissipation, the thickness of the intermediate layer is more than 2 mm, for example, 3, 4, 5, 6 mm, etc. The specific thickness can be designed according to the diameter of the cylinder, the thickness of the inner pot and the outer heating layer, etc.
