Abstract
Description
Technical Field
[0001] This utility model belongs to the field of seasoning stir-frying technology, and in particular relates to a seasoning stir-frying device. Background Technology
[0002] Seasonings are flavoring agents composed of various ingredients, including naturally grown plants such as star anise and fennel. Seasonings need to be stir-fried or cooked to bring out their flavor components. Currently, most stir-frying methods utilize drum-type stir-frying machines.
[0003] Its main structure includes a frying machine body and a frying drum installed inside the frying machine body. The frying drum is equipped with a blade structure for frying materials. By changing the blade structure, it can serve as a frying plate for frying materials. At the same time, during the frying process, the materials are pushed by the arranged blades. After the frying is completed, the frying drum is rotated in the opposite direction by the frying machine body, and the materials in the frying drum are pushed out of the discharge port of the frying drum by the push of the blades.
[0004] During the stir-frying process of seasonings, especially when stir-frying materials with pungent odors, such as chili powder and mustard, a large amount of pungent dust escapes from the opening of the stir-frying drum while the powders (especially highly pulverized powders) are being stir-fried. This is especially true when the stir-frying drum rotates at a high speed to prevent the materials from gelatinizing.
[0005] Therefore, existing technologies use exhaust hoods or other dust removal devices installed above the cooking drum. However, the vertical exhaust hood has a large gap with the horizontal cooking drum, and the exhaust direction is vertical. As a result, the dust removal effect is not good, and some of the loose powder (irritating) can still easily disperse into the workshop.
[0006] Therefore, in actual production, the fan hood is designed to face the opening of the frying cylinder. However, the space is limited when adding or dispensing ingredients due to the fan hood's obstruction. Furthermore, there is still a gap between the air inlet of the fan hood and the opening of the frying cylinder, so light powders (such as chili powder) can still easily escape during the frying process. Utility Model Content
[0007] Based on the above background, the purpose of this utility model is to provide a seasoning stir-frying device.
[0008] To achieve the above objectives, the present invention adopts the following technical solution:
[0009] A seasoning stir-frying device includes a drum stir-fryer, the drum stir-fryer including a stir-fryer body and a stir-frying cylinder rotatably connected inside the stir-fryer body, characterized in that it further includes a pushing and dust extraction mechanism;
[0010] The dust extraction mechanism includes a movable exhaust pipe, which is equipped with and connected to a hood structure. The air outlet of the hood structure is connected to a retractable spring tube, and the air outlet of the spring tube is connected to an external exhaust pipe.
[0011] The exhaust pipe is fixedly installed with a touch wheel structure that rolls against the outer wall of the stir-frying cylinder. During the stir-frying process, the exhaust pipe is pushed into the stir-frying cylinder; the touch wheel structure rolls against the outer wall of the stir-frying cylinder.
[0012] Preferably, the end of the exhaust pipe facing the stir-frying cylinder has a concave structure, and during the dust extraction process, the concave structure of the exhaust pipe extends into the stir-frying cylinder.
[0013] Preferably, the contact wheel structure includes an annular bracket fixedly installed on the exhaust pipe. Several circumferentially distributed contact rollers are installed on the side of the annular bracket facing the stir-frying cylinder. Each contact roller includes a roller and a roller bracket rotatably connected to the roller. The roller bracket is fixedly installed on the annular bracket.
[0014] Preferably, a fixing ring is fixedly connected to the opening of the stir-frying cylinder, and the abutment roller rolls against the outer wall of the fixing ring.
[0015] The inner side of the fixing ring is integrally formed with an annular partition boss.
[0016] Preferably, the wind shroud structure includes a wind shroud;
[0017] The air inlet end of the hood is integrally formed with a connecting pipe, which is fixedly installed on the exhaust pipe by a flange.
[0018] The exhaust pipe is fixedly connected to a mounting base, which has an exhaust port. The connecting flange is fastened to the mounting base with bolts.
[0019] Preferably, the air outlet of the hood is connected to a spring tube via a flange, and the air outlet of the spring tube is connected to an external exhaust pipe via a flange.

[0023] Preferably, the pushing structure further includes hydraulic cylinders respectively installed on both sides of the roasting machine body, the piston rod of the hydraulic cylinder being fixedly mounted with a pull rod, and the pull rod being fixedly mounted on the pushing bracket.
[0024] Preferably, an air hood is installed inside the air inlet end of the exhaust pipe;
[0025] The air hood is conical in shape, and the cross-section of the air outlet end of the air hood is smaller than the cross-section of the air inlet end.
[0026] This utility model has the following beneficial effects:
[0027] 1. By pushing the dust extraction mechanism; during the frying process, the exhaust end of the pushing dust extraction mechanism is extended into the frying cylinder to extract the dust generated during the frying process, thereby minimizing the escape of irritating dust outside the cylinder.

[0040] Example 1
[0041] like Figure 1-4 As shown, a seasoning frying device includes a drum frying machine. The drum frying machine is a conventional drum frying machine disclosed in the prior art. Its main structure includes a frying machine body 1 and a frying cylinder 11 rotatably connected inside the frying machine body 1. During the frying process, the operator puts the frying material into the frying cylinder 11, and the rotating frying cylinder 11 stirs the material.
[0042] Similar to the existing drum roasting machine, several roasting blades are installed on the inner wall of the roasting cylinder 11. The roasting blades are used to turn the material over. After roasting, the material is fed out by changing the rotation direction of the roasting cylinder 11 under the push of the roasting blades.
[0043] Those skilled in the art can understand the specific structure and working principle of the drum roasting machine disclosed in this utility model by consulting technical manuals and dictionaries.
[0044] In the process of stir-frying ingredients, especially when stir-frying ingredients containing irritating substances (such as chili powder and mustard powder), in order to prevent irritating dust from escaping into the workshop, this utility model makes the following improvements:
[0045] The seasoning frying device also includes a dust extraction mechanism 3; through the dust extraction mechanism 3, the exhaust end of the dust extraction mechanism 3 is extended into the frying cylinder 11 during the frying process, so as to extract the dust generated by the frying process inside the frying cylinder 11, thereby minimizing the escape of irritating dust outside the cylinder.
[0046] Specifically, the dust extraction mechanism 3 includes a movable exhaust pipe 31 (the exhaust pipe 31 can be moved away for easy operation during feeding or unloading). The exhaust pipe 31 is equipped with a hood structure, and the air outlet of the hood structure is connected to a retractable spring pipe 36. According to the existing exhaust method, the air outlet of the spring pipe 36 (the air outlet position is equipped with a flange 361) is connected to an external exhaust pipe (specifically, the same as the existing exhaust structure, an external exhaust pipe is installed in the workshop, and a fan such as an axial flow fan is installed at the air outlet of the external exhaust pipe to realize the extraction of dust. The external exhaust pipe is not shown in the figure).
[0047] A touch wheel structure is fixedly installed on the exhaust pipe 31, which rolls against the outer wall of the stir-frying cylinder 11. During the stir-frying process, the exhaust pipe 31 is pushed into the stir-frying cylinder 11; the touch wheel structure rolls against the outer wall of the stir-frying cylinder 11.
[0048] The stability of the exhaust pipe 31 is maintained by the contact wheel structure. When the exhaust pipe 31 is inserted into the roasting cylinder 11, the contact wheel structure rolls against the roasting cylinder 11. Therefore, the contact wheel structure limits the exhaust pipe 31 so that it does not easily shake. This solves the problem of the exhaust pipe 31 shaking during the exhaust process (affected by airflow, the exhaust pipe 31 is prone to slight shaking during the exhaust process. In order to increase the dust removal effect and greatly reduce the dust from escaping outside the roasting cylinder 11, the exhaust pipe 31 is inserted into the roasting cylinder 11. Although a certain safety gap is maintained between the exhaust pipe 31 and the inner wall of the roasting cylinder 11, the gap is designed to be small) causing it to touch the inner wall of the rotating roasting cylinder 11 and thus cause mechanical collision.
[0049] Example 2
[0050] like Figure 1-4 As shown, in this embodiment, based on the structure of embodiment 1, the exhaust pipe 31 is provided with a concave structure 311 at one end (left end) facing the stir-frying cylinder 11. During the dust extraction process, the concave structure 311 of the exhaust pipe 31 extends into the stir-frying cylinder 11.
[0051] The contact wheel structure includes an annular bracket 32 fixedly installed on the exhaust pipe 31. Several circumferentially distributed contact rollers are installed on the side of the annular bracket 32 facing the stir-frying cylinder 11. The contact rollers include rollers 34 and roller brackets 33 rotatably connected to the rollers 34. The roller brackets 33 are fixedly installed on the annular bracket 32 (specifically, fixed on the annular bracket 32 by bolts).
[0052] Meanwhile, a fixing ring 21 is fixedly connected to the opening of the stir-frying cylinder 11, and the abutting roller 34 abuts and rolls on the outer side wall of the fixing ring 21; an annular partition protrusion is integrally formed on the inner side of the fixing ring 21.
[0053] During operation, when the exhaust pipe 31 extends into the roasting cylinder 11, the contact roller 34 abuts against the fixing ring 21 installed at the opening of the roasting cylinder 11. As the roasting cylinder 11 rotates, the contact roller 34 rolls. During exhaust, dust and airflow enter from the air inlet of the exhaust pipe 31. Because the contact roller 34 is engaged and stopped, the relative posture between the exhaust pipe 31 and the roasting cylinder 11 remains unchanged, thus preventing the outer wall of the exhaust pipe 31 from contacting the rotating roasting cylinder 11 and causing mechanical friction.
[0054] In this method, dust is removed by drawing air from inside the stir-frying cylinder 11 during the working process, which greatly improves the dust removal effect.
[0055] Example 3
[0056] like Figure 1-4 As shown, in this embodiment, based on the structure of embodiment 2, the above-mentioned hood structure includes a hood 35; the air inlet end of the hood 35 is integrally formed with a connecting pipe 351, and the connecting pipe 351 is fixedly installed on the exhaust pipe 31 by a flange.
[0057] Meanwhile, a mounting base is fixedly connected to the air outlet end of the exhaust duct 31, and an air outlet is provided on the mounting base. The connecting flange is fastened to the mounting base with bolts. The air outlet end of the hood 35 is connected to the spring tube 36 (the spring tube 36 is a conventional spring tube 36 disclosed in the prior art) via a flange, and the air outlet end of the spring tube 36 is connected to an external exhaust duct via a flange. The spring tube 36 enables the hood 35 structure and the exhaust duct 31 to move horizontally.
[0058] Specifically, a pushing structure is fixedly installed at the bottom of the pushing dust extraction mechanism 3; the pushing structure includes a pushing bracket 41 (mounting columns 411 are fixedly installed on both sides of the top of the pushing bracket 41, and the mounting columns 411 are fixedly installed at the bottom of the hood 35 and the exhaust pipe 31), and rail wheels 42 are rotatably connected to both sides of the pushing bracket 41, and rails are fixedly installed on both sides of the roasting machine body 1; the rail wheels 42 roll on the rails.
[0059] Meanwhile, the pushing structure also includes hydraulic cylinders 43 respectively installed on both sides of the main body 1 of the stir-frying machine. The piston rod of the hydraulic cylinder 43 is fixedly installed with a pull rod 431, and the pull rod 431 is fixedly installed on the pushing bracket 41 (a boss is fixedly installed on the pushing bracket 41, and the pull rod 431 is installed on the boss).
[0060] During operation, once the material feeding and roasting cylinder 11 is completed, the operator opens the hydraulic cylinder 43. Driven by the hydraulic cylinder 43, the wind hood 35 structure and the exhaust pipe 31 are moved to the left until the exhaust pipe 31 extends into the roasting cylinder 11 for ventilation and dust removal.
[0061] During this process, the spring tube 36 is stretched. Conversely, during the frying process, the hydraulic cylinder 43 pushes the wind cover 35 structure and the exhaust pipe 31 to detach, facilitating material discharge.
[0062] This method enables the heavy wind shield 35 structure and exhaust pipe 31 to be moved by hydraulic propulsion.
[0063] Example 4
[0064] like Figure 1-4 As shown, in this embodiment, based on the structure of embodiment 3, an air duct 5 is installed inside the air inlet end of the above-mentioned exhaust pipe 31; the air duct 5 is conical in shape, and the air outlet section of the air duct 5 is smaller than the air inlet section.
[0065] An annular seat 51 is fixedly connected to the opening of the air hood 5. The annular seat 51 is fixedly installed on the inner wall of the exhaust pipe 31 by several bolts.
[0066] The structural design of the air hood 5 enables airflow and dust to enter the exhaust duct 31. Under the guidance of the air hood 5, the airflow and dust are discharged from the inner end (right end air outlet) of the air hood 5. At this time, since the air hood 5 is conical, when the airflow reaches the inner end of the air hood 5, the airflow is accelerated (determined by the fluid properties of the airflow, the airflow velocity increases when the airflow is discharged from the small diameter air outlet). By increasing the airflow velocity, the airflow carries the dust (irritating substances) and accelerates its introduction into the air hood 35 structure, thus further preventing the escape of irritating dust.
[0067] Example 5
[0068] like Figure 1-4 As shown, this embodiment is based on the structure of embodiment 4. In order to facilitate the discharge of materials after the roasting drum 11 has finished roasting, a material collection hopper (not shown in the figure) is placed below the roasting machine body 1. During the discharge process, since the hood structure is far away from the roasting machine body 1, it is convenient for the operator to collect the materials.
[0069] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
