Embodiment 1
[0026] like figure 1 , a cereal drying device, comprising a bracket 1 and a drying cylinder 2 arranged on the bracket 1, the top of the drying cylinder 2 is provided with a feed port 3 and an air outlet 4, and the bottom of the drying cylinder 2 is provided with an outlet Material port 5. In this embodiment, the feeding port 3 is in the shape of a trumpet whose upper opening diameter is larger than that of the lower opening. In the cereal drying device of the present invention, there can be 3-5 air outlet holes 4, and the diameter of the air outlet holes 4 is 1.5-3.5 mm. In this embodiment, there are 5 air outlet holes 4, all of which are located in the drying cylinder. 2, and the aperture of the air outlet hole 4 is preferably 2 mm to ensure that the air flows out while preventing the oatmeal from being blown out thereupon. Simultaneously, the joint between the discharge port 5 and the side wall of the drying cylinder 2 is set on a downward slope, so as to increase the spee...
Embodiment 2
[0032] This embodiment is roughly the same as Embodiment 1, except that the drying cylinder 2 is mainly made of the following materials: 30 parts of aluminum nitride, 18 parts of nickel-cobalt alloy, 25 parts of magnesium oxide, and 10 parts of aluminum oxide , 8 parts of silicon carbide, 1 part of borax, 0.8 part of titanium dioxide, 0.1 part of antioxidant, and 0.5 part of binder. Wherein, the antioxidant is formed by mixing boron oxide and tin oxide at a ratio of 1:1, and the binder is a composition of sodium silicate and gypsum. Due to its high stability, good thermal conductivity, and small thermal expansion coefficient, aluminum nitride can be used as a good thermal shock resistant material, and its ability to resist molten metal erosion is strong, and it is also an electrical insulator. It is combined with nickel-cobalt alloys and magnesium oxide , alumina, silicon carbide, borax, titanium dioxide and other high temperature resistant, high hardness, high strength and re...
Embodiment 3
[0034] This embodiment is roughly the same as Embodiment 1, except that the drying cylinder 2 is mainly made of the following materials: 25 parts of aluminum nitride, 15 parts of nickel-cobalt alloy, 30 parts of magnesium oxide, and 5 parts of aluminum oxide , 5 parts of silicon carbide, 4 parts of borax, 0.5 part of titanium dioxide, 0.4 part of antioxidant, and 0.3 part of binder. Wherein, the antioxidant is tin oxide, and the binder is a composition of sodium silicate, clay and gypsum. Due to its high stability, good thermal conductivity, and small thermal expansion coefficient, aluminum nitride can be used as a good thermal shock resistant material, and its ability to resist molten metal erosion is strong, and it is also an electrical insulator. It is combined with nickel-cobalt alloys and magnesium oxide , alumina, silicon carbide, borax, titanium dioxide and other high temperature resistant, high hardness, high strength and refractory materials are fully combined, and th...
