Description

Technical Field

[0001] This utility model relates to the field of steaming and frying technology for rapeseed oil production, and in particular to a steaming and frying device for rapeseed oil production that can heat evenly. Background Technology

[0002] Rapeseed oil production mainly includes pretreatment, pressing / extraction, and refining. Steaming and roasting is one of the core processes in the pretreatment stage. This process involves precise control of temperature, moisture, and time to induce physical and chemical changes in the rapeseed, such as protein denaturation, cell structure destruction, and reduced oil viscosity. These changes can significantly improve the oil yield, while also deactivating harmful substances such as lipases and reducing the risk of rancidity. The quality of steaming and roasting directly affects the subsequent pressing efficiency and extraction effect, and provides a more stable crude oil quality for the refining process. It is a key link in ensuring both the yield and quality of the oil.

[0003] Existing steaming and frying equipment for rapeseed oil production has significant drawbacks in the stirring process. Traditional layered steaming and frying pans use fixed stirring fins, which leads to the formation of stirring dead zones at the edges and bottom of the pan, resulting in uneven heating of the rapeseed. This, in turn, causes some rapeseed to be over- or under-cooked, significantly increasing the burden on subsequent refining processes.

[0004] Therefore, in view of the existing problems of poor stirring effect and poor processing effect of rapeseed, there is a need for a steaming and frying device for rapeseed oil production that can uniformly heat the rapeseed and solve the above problems. Utility Model Content

[0005] To address the problems of poor stirring and processing effects of rapeseed in existing technologies, this application provides a steaming and frying device for rapeseed oil production that can be heated evenly.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A steaming and frying device for rapeseed oil production capable of uniform heating includes a processing chamber, a heating chamber fixedly connected to the outer wall of the processing chamber, a connecting shell fixedly connected to the top of the processing chamber, a drive motor fixedly connected to the right end of the connecting shell, a stirring plate two and a stirring plate one connected to the drive end of the drive motor via a material turning assembly, both stirring plates one and two having a plurality of shearing holes on their outer walls, a heating wire installed on the inner wall of the heating chamber, a fixing shell fixedly connected to the right end of the heating chamber, and a circulating fan connected to the inner wall of the fixing shell via a heating assembly.

[0008] As a further improvement of this utility model, the material turning assembly includes a reciprocating lead screw fixedly connected to the heating wire drive end, and a slider is sleeved on the outer wall of the reciprocating lead screw.

[0009] As a further improvement of this utility model, a movable plate is fixedly connected to the outer wall of the slider, a toothed groove is provided at the top of the movable plate, the bottom end of the movable plate is slidably connected to the top of the processing chamber, a driven gear is meshed with the toothed groove at the movable plate, and a bevel gear is fixedly connected to the front end of the driven gear.

[0010] As a further improvement of this utility model, a transmission pipe is fixedly connected to the top of the second stirring plate, and a second bevel gear is fixedly connected to the top of both the transmission pipe and the transmission rod. The second bevel gear and the first bevel gear are meshed together.

[0011] As a further improvement of this utility model, a transmission rod is fixedly connected to the top of the first stirring plate through the second stirring plate.

[0012] As a further improvement of this utility model, the heating group includes a dust filter screen fixedly connected to the right end of the fixed shell, an air supply pipe fixedly connected to the top of the heating chamber, and the other end of the air supply pipe fixedly connected to the outer wall of the top of the processing chamber.

[0013] As a further improvement of this utility model, a pull rod is slidably connected to the right end of the fixed shell, and a cleaning wheel is rotatably connected to the inner wall of the pull rod.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0015] In this invention, after rapeseed is placed into the processing chamber, the drive motor is started to rotate the reciprocating screw, which in turn causes the moving plate to move back and forth via the slider, driving the driven gear to rotate back and forth. The driven gear drives bevel gear one and bevel gear two, causing the transmission rod and transmission tube to rotate synchronously in opposite directions, which in turn causes stirring plates one and two to rotate and tumble the rapeseed. This design significantly improves the uniformity of heating of the rapeseed, optimizes the physicochemical changes, reduces energy consumption, and improves the oil yield and oil quality.

[0016] In this invention, after the heating wire is activated, its heat directly heats the rapeseed in the processing chamber for the first layer of heating. Simultaneously, a circulating fan is activated, drawing in air filtered through a dust filter and delivering it into the heating chamber. This air mixes with the hot air from the heating wire to form a high-temperature airflow, which is then introduced into the processing chamber through an air supply pipe, achieving the second layer of heating. This dual-layer heating mechanism significantly improves the uniformity of heating the rapeseed, optimizes physicochemical changes, reduces energy consumption, and increases production efficiency.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0025] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] Example 1: A steaming and frying device for rapeseed oil production that can be heated evenly includes a processing chamber 1, a heating chamber 2 fixedly connected to the outer wall of the processing chamber 1, a connecting shell 4 fixedly connected to the top of the processing chamber 1, a drive motor 18 fixedly connected to the right end of the connecting shell 4, a stirring plate 17 and a stirring plate 16 connected to the drive end of the drive motor 18 via a material turning assembly, the material turning assembly includes a reciprocating screw 9 fixedly connected to the drive end of the heating wire 8, a slider 19 sleeved on the outer wall of the reciprocating screw 9, a moving plate 10 fixedly connected to the outer wall of the slider 19, a toothed groove provided at the top of the moving plate 10, and a sliding connection at the bottom end of the moving plate 10 to the top of the processing chamber 1, a bevel gear 13 fixedly connected to the top of the transmission pipe 15 and the transmission rod 14, a driven gear 11 meshing with the toothed groove at the moving plate 10, a bevel gear 12 fixedly connected to the front end of the driven gear 11, and a meshing connection between the bevel gear 13 and the bevel gear 12.

[0028] Specifically: In the steaming and roasting device for rapeseed oil production, after the rapeseed is put into the processing chamber 1, the drive motor 18 is started. The drive motor 18 drives the reciprocating screw 9 to rotate through the transmission mechanism. The rotational motion of the reciprocating screw 9 is converted into the reciprocating linear motion of the moving plate 10 through the slider 19. The reciprocating motion of the moving plate 10 further drives the driven gear 11 connected to it to rotate reciprocally. The rotation of the driven gear 11 drives the bevel gear 12 to rotate through the meshing action. The bevel gear 12 meshes with the bevel gear 13, so that the transmission rod 14 and the transmission tube 15 achieve synchronous rotation in opposite directions. The opposing rotations of the transmission rod 14 and the transmission pipe 15 respectively drive the stirring plate 16 and the stirring plate 17 to tumble the rapeseed in the processing chamber 1 in a multi-rotation manner. This multi-rotation tumbling mechanism can effectively break up rapeseed clumps, increase the contact area between rapeseed and the heat medium, and significantly improve the uniformity of rapeseed heating. Through this design, the steaming and roasting device not only optimizes the physicochemical changes of rapeseed (such as cell structure destruction and oil release), but also reduces the phenomenon of local overheating or insufficient steaming and roasting, thereby improving the oil yield and oil quality, while reducing energy consumption and creating more favorable conditions for subsequent pressing or leaching processes.

[0029] Example 2: Both stirring plate 16 and stirring plate 17 have several shearing holes on their outer walls. Heating wire 8 is installed on the inner wall of heating chamber 2. A fixed shell 3 is fixedly connected to the right end of heating chamber 2. A circulating fan 20 is connected to the inner wall of fixed shell 3 through a heating assembly. The heating assembly includes a dust filter 21 fixedly connected to the right end of fixed shell 3. An air supply pipe 5 is fixedly connected to the top of heating chamber 2. The other end of air supply pipe 5 is fixedly connected to the outer wall of the top of processing chamber 1. A pull rod 6 is slidably connected to the right end of fixed shell 3. A cleaning wheel 7 is rotatably connected to the inner wall of pull rod 6.

[0030] Specifically, in the steaming and roasting device for rapeseed oil production, after the heating wire 8 is activated, it begins to heat up, directly heating the rapeseed in the processing chamber 1 for the first layer of heating. Simultaneously, the circulating fan 20 is activated, drawing in outside air through the air intake. This air is filtered through the dust filter 21 before entering the heating chamber 2. Inside the heating chamber 2, the filtered air comes into full contact with the heat emitted by the heating wire 8 and is heated, forming a high-temperature airflow. This high-temperature airflow is then transported from the heating chamber 2 to the processing chamber 1 through the air supply pipe 5, providing a second layer of heating for the rapeseed. This dual-layer heating mechanism not only improves heat utilization efficiency but also ensures a more uniform temperature distribution within the processing chamber 1 through the continuous operation of the circulating fan 20, avoiding localized overheating or underheating. The air entering the heating chamber 2 is clean and dust-free thanks to the filtration effect of the dust filter 21, which avoids the impact of impurities on the rapeseed and heating wire 8, further improving the heating effect and the steaming and roasting quality of the rapeseed. This design significantly optimizes the physicochemical changes of the rapeseed (such as protein denaturation and oil release), providing higher quality raw materials for subsequent pressing or leaching processes, while reducing energy consumption and improving production efficiency.

[0031] As one of the optimized structural designs for Example 1, such as Figures 1-4 As shown, a transmission tube 15 is fixedly connected to the top of the second mixing plate 17, and a transmission rod 14 is fixedly connected to the top of the first mixing plate 16 through the second mixing plate 17. A pull rod 6 is slidably connected to the right end of the fixed shell 3. A cleaning wheel 7 is rotatably connected to the inner wall of the pull rod 6. By pulling the pull rod 6, the cleaning wheel 7 cleans the dust filter 21 and maintains the dust filtering effect of the dust filter 21.

[0032] Working principle: When rapeseed is put into processing chamber 1, the drive motor 18 is started to drive the reciprocating screw 9 to rotate. The reciprocating screw 9 drives the moving plate 10 to move back and forth through the slider 19. The moving plate 10 drives the driven gear 11 to rotate back and forth. When the driven gear 11 rotates, the first bevel gear 12 drives the second bevel gear 13, causing the transmission rod 14 and the transmission pipe 15 to rotate synchronously in opposite directions. The second stirring plate 17 and the first stirring plate 16 tumble the rapeseed in processing chamber 1 through multiple rotations, improving the uniformity of rapeseed heating. After the heating wire 8 is started, it generates heat to heat the rapeseed in processing chamber 1. When the circulating fan 20 is started, it can draw in air filtered by the dust filter 21 and fill the heating chamber 2. The hot air emitted by the heating wire 8 in the heating chamber 2 is poured into the processing chamber 1 through the air supply pipe 5, forming double-layer heating and improving the heating effect of rapeseed.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
