Description

Technical Field

[0001] This utility model relates to the field of rapeseed processing technology, and in particular to an automatic rapeseed stir-frying device. Background Technology

[0002] Rapeseed is an oilseed crop. The main processing method is to roast the rapeseed and then press it to obtain rapeseed oil.

[0003] A search revealed an automated rapeseed oil roasting device (publication number: CN219079412U), comprising a support base and a roasting pan for roasting seeds. The top of the support base has a groove, and a heating plate is fixedly installed in the groove. The roasting pan is slidably installed in the groove on the top of the support base. A discharge mechanism is provided on one side of the roasting pan. A sealing plate is fixedly installed on the top of the support base through two protrusions. A through-type rotating shaft is rotatably installed on the sealing plate. Three arrayed stirring rods are fixedly installed on the bottom side wall of the rotating shaft. A drive mechanism for driving the rotating shaft to rotate is provided on the top of the sealing plate.

[0004] Existing technology mainly uses a motor to drive a stirring rod to rotate and turn the rapeseed. However, the rapeseed has poor vertical flow and is prone to local overheating, resulting in a bitter taste. The stirring rod can only rotate in a circumferential direction and cannot promote the vertical flow of the rapeseed. Therefore, the efficiency and effect of roasting are not good, and there is room for optimization.

[0005] Therefore, we propose an automatic rapeseed stir-frying device. Utility Model Content

[0006] The present invention mainly solves the technical problem of poor vertical flow of rapeseed and provides an automatic rapeseed stirring device.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: an automatic rapeseed stir-frying device, comprising:

[0008] The outer casing has a liftable sealing cover on its top and a stirring structure below the sealing cover. The stirring structure includes a stirring rod, dynamic stirring blades, and static stirring blades. Several static stirring blades are fixedly installed on the inner wall of the outer casing. The stirring rod is rotatably connected to the sealing cover. The sealing cover is equipped with a motor-driven stirring rod, and several dynamic stirring blades are fixedly installed on the stirring rod.

[0009] In a preferred embodiment of this utility model, the outer shell has a double-layer structure, with a heating cavity formed between the inner and outer layers of the outer shell. The heating cavity is provided with a plurality of heating rods, which are fixedly connected to the inner layer of the outer shell.

[0010] In a preferred embodiment of this utility model, a bushing is fixedly installed at the bottom of the sealing cover, the stirring rod is rotatably connected to the bushing, the stirring rod is fixedly connected to the output shaft of the motor, and the motor is fixedly installed on the top surface of the sealing cover.

[0011] In a preferred embodiment of this invention, the dynamic stirring blades are formed into a spiral plate, and at least three dynamic stirring blades are provided on the circumferential surface of the stirring rod.

[0012] In a preferred embodiment of this invention, the static stirring blade forms a spiral plate with the same spiral direction as the dynamic stirring blade, and the static stirring blade does not come into contact with the dynamic stirring blade.

[0013] In a preferred embodiment of this utility model, a push rod and a telescopic rod are fixedly installed on the outer wall of the outer shell, and the output shafts of the push rod and the telescopic rod are both fixedly connected to the sealing cover.

[0014] In a preferred embodiment of this invention, a pipe for feeding is fixedly installed on the top of the sealing cover, and a window for discharging is provided at the bottom of the outer shell.

[0015] Beneficial effects

[0016] This utility model provides an automatic rapeseed stir-frying device. It has the following beneficial effects:

[0017] 1. This automatic rapeseed stir-frying device uses a liftable sealing cover to drive a motor and stirring rod to move inside the outer shell. Simultaneously, the motor also drives the stirring rod and multiple dynamic stirring blades in a circular motion. The dynamic stirring blades propel the material flow in both radial and horizontal directions around the outer shell. Combined with multiple static stirring blades, this significantly improves the fluidity of the rapeseed within the outer shell, ensuring uniform stir-frying. The spiral-shaped dynamic and static stirring blades reduce shear force on the rapeseed, preventing damage to the outer layer during stir-frying. Furthermore, the spiral-shaped static stirring blades increase the contact area between the rapeseed and the heating element, enhancing the heating effect.

[0018] 2. This automatic rapeseed stir-frying device uses a push rod to push the sealing cover upward, which in turn drives the output shaft of the telescopic rod to extend, thereby ensuring the stable vertical displacement of the sealing cover. The sealing cover drives the stirring rod and multiple dynamic stirring blades to move radially along the outer shell, thereby turning the rapeseed inside the shell up and down. The turning position is continuously adjusted to ensure that the rapeseed is heated evenly, avoiding local overheating that produces bitterness, and also inhibiting the rapeseed from clumping during the stir-frying process.

[0025] An automatic rapeseed stir-frying device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes:

[0026] The outer casing 10 has a retractable sealing cover 11 on its top. Below the sealing cover 11 is a stirring structure, which includes a stirring rod 12, dynamic stirring blades 13, and static stirring blades 14. Several static stirring blades 14 are fixedly installed on the inner wall of the outer casing 10. The stirring rod 12 is rotatably connected to the sealing cover 11. A motor-driven stirring rod 12 is mounted on the sealing cover 11. Several dynamic stirring blades 13 are fixedly installed on the stirring rod 12. The outer casing 10 has a double-layer structure, with a heating chamber formed between the inner and outer layers. The heating chamber contains several... The heating rod 15 is fixedly connected to the inner layer of the outer shell 10. A bushing is fixedly installed at the bottom of the sealing cover 11. The stirring rod 12 is rotatably connected to the bushing. The stirring rod 12 is fixedly connected to the output shaft of the motor. The motor is fixedly installed on the top surface of the sealing cover 11. The dynamic stirring blade 13 forms a spiral plate. At least three dynamic stirring blades 13 are provided on the circumferential surface of the stirring rod 12. The static stirring blade 14 forms a spiral plate with the same spiral direction as the dynamic stirring blade 13. The static stirring blade 14 does not contact the dynamic stirring blade 13.

[0027] In this design, the motor, heating rod 15, and push rod 16 need to be connected to a controller. A temperature sensor should also be installed on the top of the sealing cover 11 to monitor the temperature inside the outer shell 10 to ensure effective stir-frying of the rapeseed. The liftable sealing cover 11 drives the motor and stirring rod 12 to move within the outer shell 10. Simultaneously, the motor drives the stirring rod 12 and multiple dynamic stirring blades 13 in a circular motion. The dynamic stirring blades 13 push the material to flow in both radial and horizontal directions within the outer shell 10. Combined with multiple static stirring blades 14, this significantly improves the fluidity of the rapeseed within the outer shell 10, ensuring uniform stir-frying. The spiral dynamic stirring blades 13 and static stirring blades 14 reduce shear force on the rapeseed, preventing damage to the outer layer during stir-frying. Furthermore, the spiral static stirring blades 14 increase the contact area between the rapeseed and the heating rod 15, enhancing the heating effect.

[0028] like Figure 3 As shown, a push rod 16 and a telescopic rod 17 are fixedly installed on the outer wall of the outer casing 10. The output shafts of the push rod 16 and the telescopic rod 17 are fixedly connected to the sealing cover 11. A pipe for feeding is fixedly installed on the top of the sealing cover 11, and a window for discharging is opened at the bottom of the outer casing 10.

[0029] Pushing the sealing cover 11 upward by the push rod 16, the sealing cover 11 drives the output shaft of the telescopic rod 17 to extend, thereby ensuring the stable displacement of the sealing cover 11 in the vertical direction. The sealing cover 11 drives the stirring rod 12 and multiple dynamic stirring blades 13 to move radially along the outer shell 10, thereby turning the rapeseed inside the outer shell 10 up and down. The turning position is continuously adjusted to ensure that the rapeseed is heated evenly, avoids local overheating and bitterness, and can also inhibit the rapeseed from clumping during the roasting process.

[0030] The working principle of this utility model is as follows: the push rod 16 pushes the sealing cover 11 to rise, and the sealing cover 11 drives the output shaft of the telescopic rod 17 to extend, thereby ensuring the stable displacement of the sealing cover 11 in the vertical direction. The liftable sealing cover 11 drives the motor and the stirring rod 12 to move inside the outer shell 10. At the same time, the motor can also drive the stirring rod 12 and multiple dynamic stirring blades 13 to move in a circular motion. The dynamic stirring blades 13 push the material to flow, and the flow direction includes the radial and horizontal directions of the outer shell 10. With the help of multiple static stirring blades 14, the fluidity of the rapeseed inside the outer shell 10 is greatly improved, thereby ensuring the uniformity of stir-frying. After stir-frying, the rapeseed is discharged from the window at the bottom of the outer shell 10. A valve needs to be installed at the window to control its opening and closing.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
