[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] Please refer to Figures 1-3 , an embodiment provided by the present utility model: a rotary drum type electromagnetic heating automatic separation hot medium hulled barley roasting machine, including a machine body 1, a feed hopper 2 is provided at one end of the machine body 1, the bottom of the feed hopper 2 is connected to a drum 4 through a feed auger 3, a discharge hopper 5 is provided below the feed hopper 2, a heat dissipation cover 6 is provided above the drum 4, an electromagnetic heating coil 7 is provided below the drum 4, and an electric control box 8 is provided at the rear of the drum 4;

[0020] The drum 4 is a three-layer drum structure, and the drum 4 is divided into an outer layer drum 11, an intermediate layer drum 12, and an inner layer drum 13 by a first partition 9 and a second partition 10. The feed auger 3 is connected to the inner layer drum 13, the discharge hopper 5 is connected to the outer layer drum 11, a first baffle 14 is provided between the ends of the outer layer drum 11 and the intermediate layer drum 12, a second baffle 15 is provided between the ends of the intermediate layer drum 12 and the inner layer drum 13, and spiral blades 16 are provided on the inner side walls of the outer layer drum 11, the intermediate layer drum 12, and the inner layer drum 13.

[0021] Furthermore, the length of the first partition 9 is shorter than the length of the second partition 10; so that the medium always circulates in the cylinder.

[0022] Further, the spiral blade directions of the inner layer drum 13 and the middle layer drum 12 are the same, while the spiral blade direction of the outer layer drum 11 is opposite to those of the middle layer drum 12 and the inner layer drum 13; this will lengthen the frying process and separate the materials more thoroughly.

[0023] Further, the second partition plate 10 is a perforated plate; this facilitates the outflow of the medium.

[0025] Further, the feeding auger 3 is driven by a motor 17.

[0026] The working principle of the present utility model is as follows: Materials enter the outer layer drum 11 from the feeding hopper 2, and are heated by the electromagnetic heating coil 7. The materials are conveyed inward through the spiral blade 16, enter the inner layer drum 13 through the first baffle 14, and are output to the discharging hopper 5 through the reverse spiral blade 16 of the inner layer drum 13. The medium is output to the middle layer drum 12 through the perforated plate of the second partition plate 10, and is conveyed back to the material inlet through the reverse blade of the middle layer drum 12, repeatedly mixing and heating with the materials, so as to achieve the purpose of minimizing heat energy loss.

[0027] The drum of the present utility model is provided with a three-layer structure, and the materials are heated in a cycle within the drum, so that the thermal efficiency is effectively utilized.
