[0034] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0035] like Figure 1-3 As shown, the utility model provides an oatmeal baking machine, which comprises: a heating box 1, a pneumatic mixing and stirring component and a dehumidifier 5;

[0036] The pneumatic mixing and stirring assembly comprises: a stirring shaft 2, a gas heater 3 and a stirring blade 4; wherein,

[0037] A stirring shaft 2 with an internal hollow structure is vertically and rotatably arranged inside the heating box 1, and a plurality of stirring blades 4 with an internal hollow structure are evenly and vertically fixedly arranged on the stirring shaft 2 and connected with the interior thereof. A plurality of air outlet holes 7 connected with the interior thereof are evenly opened on both sides of each stirring blade 4. A gas heater 3 for continuously conveying hot air to the interior of the stirring shaft 2 is also fixedly arranged on the heating box 1. The air inlet end of the dehumidifier 5 extends into the interior of the heating box 1 from the top thereof and is connected with the interior thereof, and the air outlet end thereof is connected with the air inlet pipe 6 of the gas heater 3, and a switch valve 15 is also fixedly arranged on the air inlet pipe 6.

[0038] In the above scheme, a heating element for heating the material is fixedly arranged in the heating box 1 (the heating element can be a heating resistance wire or a heating resistance rod fixed on the inner wall of the heating box 1).

[0039] At the initial stage of heating, the switch valve 15 is opened to connect the air inlet pipe 6 with the external environment so that the gas heater 3 heats the external environment. After the external air is heated by the gas heater 3, it enters the stirring shaft 2 and is discharged into the heating box 1 through the air outlet 7 on the multiple stirring blades 4 on the stirring shaft 2. When the multiple stirring blades 4 on the stirring shaft 2 stir the material, the heating box 1 can heat the material uniformly. At the same time, when the pneumatic mixing and stirring component mixes the material in the heating box 1, it can also transport hot air into the heating box 1 to assist the heating box 1 in heating the material, so as to improve the heating efficiency.

[0040] In addition, since the gas heated by the gas heater 3 is discharged through the stirring shaft 2 from the multiple stirring blades 4 on its shaft body, the material and the gas can be fully mixed during the mixing and stirring process, thereby improving the heating effect and efficiency.

[0041] The heated gas rises to the top of the heating box 1 and enters the dehumidifier 5. The dehumidified gas returns to the gas heater 3 for heating again. Since the gas just coming out of the heating box 1 still has residual heat, the time it takes for the gas heater 3 to heat the dehumidified gas can be shortened, thereby improving the heating efficiency.

[0042] In the above scheme, the top and bottom of the heating box 1 are respectively fixedly connected with a feed end and a discharge end, and a pressure relief pipe is fixedly provided on the top of the heating box 1, and a pressure relief valve is fixedly provided on the pressure relief pipe to prevent the gas pressure in the heating box 1 from being too high and causing an explosion.

[0043] In a preferred embodiment of the present invention, the baking machine further comprises: an air pump 8; wherein,

[0044] An air pump 8 is fixedly installed on the side wall of the gas heater 3, and the input end of the air pump 8 is connected to the interior of the gas heater 3, and the output end thereof extends into the interior from the bottom end of the heating box 1 through a connecting pipe 9 and is fixedly connected to the end of the stirring shaft 2 through a hose 10.

[0045] In the above scheme, the gas heater 3 includes a shell and a resistance heating wire arranged in the shell. When the gas enters the gas heater 3, the gas is heated so that the heated gas enters the stirring shaft 2 through the connecting pipe 9 and finally blows into the heating box 1 from the air outlet 7 on each stirring blade 4 to stir the material in the heating box 1 while uniformly heating the material through the gas to improve the heating efficiency.

[0046] During use, the outside air is sucked into the gas heater 3 through the air pump 8, and the heated gas enters the heating box 1. When the gas entering the heating box 1 is sufficient, the switch valve 15 is closed to isolate the air inlet pipe 6 from the outside environment. The gas entering the heating box 1 passes through the dehumidifier 5 and then enters the gas heater 3 again to be reheated and returns to the heating box 1 after being heated.

[0047] When the stirring shaft 2 rotates in both directions, the hose 10 is made of flexible material and can rotate in both directions together with the stirring shaft 2. During the rotation in both directions, the hose 10 will undergo a slight deformation and then rotate in the opposite direction until it is restored. Therefore, the gas can still enter the stirring shaft 2 through the deformed hose 10.

[0048] Of course, the above-mentioned hose 10 can also be replaced by a hard pipe. When it is replaced by a hard pipe, the bottom end of the rotating shaft 2 is open, and a rubber pad is fixedly provided at the open position, and the hard penetration can pierce the rubber pad at the open position of the rotating shaft 2 and extend into its inner wall. In this way, the hard pipe will not rotate with the rotating shaft 2 during the rotation process.

[0049] In a preferred embodiment of the present utility model, the dehumidifier 5 is fixed above the heating box 1, and the dehumidifier 5 includes: a drying box 501 and a water-absorbing sponge 502; wherein,

[0050] A plurality of absorbent sponges 502 are horizontally arranged at equal intervals in the height direction of the drying box 501. An opening communicating with the interior of the drying box 501 is provided on one side wall thereof, and a sealing plate capable of covering the opening is detachably provided on the side wall.

[0051] In the above scheme, when the gas entering the heating box 1 rises and passes through the dehumidifier 5, the water in the gas is absorbed by multiple absorbent sponges 502 to dry the gas. The dried gas enters the gas heater 3 again through the air inlet pipe 6 for heating. The heated gas can enter the heating box 1 again and continue to heat the material.

[0052] In addition, support bars are fixedly arranged horizontally on both sides of the drying box 501, and both sides of the water-absorbing sponge 502 are attached to the support bars by Velcro.

[0053] When the water-absorbing sponge 502 needs to be replaced, the sealing plate is removed from the open opening of the drying box 501 to replace the water-absorbing sponge 502 .

[0054] In a preferred embodiment of the present invention, the baking machine further comprises a driving assembly 12 for driving the stirring shaft 2 to rotate, wherein the driving assembly 12 comprises: a gear 1201, a rack plate 1202, a piston plate 1203 and a guide housing 1204; wherein,

[0055] A gear 1201 is coaxially fixed on the end of the stirring shaft 2, and a guide shell 1204 is horizontally fixedly provided on the side wall of the heating box 1 next to the gear 1201, and a piston plate 1203 is horizontally and movably provided inside the shell, and a rack plate 1202 that can extend into the heating box 1 and mesh with the gear 1201 is horizontally fixed on the piston plate 1203.

[0056] In the above scheme, the piston plate 1203 is made of rubber material, so that during the movement, it can ensure the sealing of the heating box 1 and prevent the hot air entering the inner side of the heating box 1 from escaping from the guide shell 1204.

[0057] When in use, the piston plate 1203 is driven to drive the rack plate 1202 to move in the horizontal direction, and the rack plate 1202 can drive the gear 1201 meshing with it to rotate during the movement, thereby driving the stirring shaft 2 and the plurality of stirring blades 4 on the shaft body to rotate alternately clockwise and counterclockwise to mix and stir the materials in the heating box 1, so as to improve the uniformity and reliability of the heating of the materials by the heating box 1 and improve the heating efficiency.

[0058] In a preferred embodiment of the present invention, the roasting machine further comprises an actuator for driving the piston plate 1203 to move in the guide housing 1204, wherein the actuator comprises: a cylinder 13 and a power rod 14; wherein,

[0059] A power rod 14 capable of passing through the guide housing 1204 is horizontally fixedly arranged on the side of the rack plate 1202 facing away from the piston plate 1203, and a vertical plate is vertically fixedly arranged on the free end of the power rod 14. The cylinder 13 is horizontally fixed on the top of the heating box 1, and the free end of the piston rod of the cylinder 13 is fixed on the vertical plate.

[0060] In the above scheme, it is difficult to drive the piston rod of the cylinder 13 to extend from or retract into the cylinder part, so as to drive the power rod 14 to move in the horizontal direction. During the movement, the piston plate 1203 can be driven to move in the guide shell 1, thereby driving the rack plate 1203 to move in the horizontal direction, and then driving the gear 1201 and the stirring shaft 2 meshing with it to rotate alternately in the forward and reverse directions, thereby driving the several stirring plates 4 on the shaft to move to mix and stir the materials in the heating box 1, so as to improve the uniformity and reliability of the heating of the materials by the heating box 1, and improve the heating efficiency.

[0061] In addition, the cylinder 13 is a well-known technical means, so its specific structure and use principle will not be repeated here.

[0062] In a preferred embodiment of the present invention, a dustproof mesh cover 16 is fixedly provided at the port of the air inlet pipe 6 .

[0063] In the above scheme, dust or other impurities are prevented from entering the gas heater 3 through the air inlet pipe 6 and then entering the heating box 1.

[0064] In a preferred embodiment of the present invention, a filter cloth or a filter screen is fixedly arranged on each of the air outlet holes 7 .

[0065] In the above solution, the filter cloth or filter screen plays a blocking role to prevent the material from entering the stirring blade 4 through the air outlet 7 during the baking process.

[0066] In a preferred embodiment of the utility model, a plurality of inverted L-shaped support legs 11 are horizontally fixedly arranged at equal intervals along the circumferential direction of the bottom of the stirring shaft 2, and a ball that can be rotatably arranged on the bottom end of each of the support legs 11 and can abut against the heating box 1.

[0067] In the above scheme, the support legs 11 are used to support the stirring shaft 2 to improve the mechanical strength of the stirring shaft 2. In addition, the sliding friction between the support legs 11 and the bottom of the heating box 1 is converted into rolling friction through ball bearings to reduce the friction between the two and extend the service life.

[0068] In summary, the oatmeal baking machine provided by the utility model overcomes the poor sealing effect of the baking machine in the prior art, so that the heat generated inside it can easily escape from the feed hopper, resulting in heat loss and energy waste. During use, the heating tube is driven by the mixer to make it contact with the material in the baking machine. Since the heating area of ​​the heating tube is small, the temperature around it is higher than other areas, and heat stratification is likely to occur, resulting in uneven heating.

[0069] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0070] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.

[0071] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
