Description

Technical Field

[0001] The present invention relates to the technical field of seasoning drying equipment, in particular to solid seasoning drying equipment. Background Art

[0002] Solid seasonings usually refer to seasonings that exist in solid form. They are generally made from natural or synthetic spices, spices, salt, sugar, flavor enhancers and other ingredients. They have the functions of enhancing food flavor, improving freshness, and removing fishy smell.

[0003] Currently, seasonings are typically dried for purposes such as extending their shelf life. Existing seasoning drying equipment typically requires the use of a tray. This means the seasonings (to be dried) are directly stacked on the tray, which is then placed in the dryer for drying. This process makes it difficult to ensure uniform drying of the stacked materials. For example, the seasoning particles on the upper layer may be dry, while those on the lower layer may still be damp, resulting in poor drying results. Summary of the Invention

[0004] The main purpose of the present invention is to provide a solid seasoning drying device, which aims to solve the problem of poor drying effect caused by seasoning stacking in the related art.

[0005] To achieve the above object, the technical solution of the present invention is as follows: A solid seasoning drying device includes a drying tank, which is provided with a feed inlet and a discharge port. The drying tank is provided with a lifting mechanism for lifting the seasoning; the lifting mechanism includes a lifting pipe, a lifting auger, and a drive motor for driving the lifting auger to rotate; the lifting pipe is provided with a circulation feed inlet and a circulation discharge port.

[0006] Furthermore, a stirring mechanism is provided in the drying tank, and the central axis of the lifting tube coincides with the rotation axis of the stirring mechanism.

[0007] Furthermore, the stirring mechanism includes a stirring paddle, which includes a driving ring, a connecting ring column, and a plurality of stirring blades. A first connecting rod for fixedly connecting the two is provided between each stirring blade and the driving ring, and each stirring blade is fixedly connected to the connecting ring column. The driving ring and the connecting ring column are both rotatably connected to the lifting tube, and the lifting tube is located in the inner ring of the connecting ring column. The circulating discharge port is located between the connecting ring column and the driving ring.

[0008] Furthermore, a drainage ring is provided on the lifting pipe, and the drainage ring is located between the circulation discharge port and the connecting column ring. The outer ring diameter of the drainage ring is larger than the outer ring diameter of the connecting ring column.

[0009] Furthermore, a second connecting rod for fixedly connecting the stirring blades and the connecting ring column is provided between each of the stirring blades and the connecting ring column, and a disturbing body is provided on each of the second connecting rods, and each of the disturbing bodies is rotatably connected to each of the second connecting rods.

[0010] Furthermore, each of the flow-disturbing bodies includes a rotating ring column and, if any, flow-disturbing blades. The rotating ring column is rotatably connected to the second connecting rod, and each of the flow-disturbing blades is fixedly connected to the rotating ring column and evenly distributed around the rotating ring column.

[0011] Furthermore, the drive ring and the lifting auger are linked to each other.

[0012] Furthermore, the lifting tube runs through the drying tank itself, the discharge port is located at the end of the lifting tube away from the driving motor, and is symmetrically distributed on both sides of the lifting tube with the circulating feed port. The lifting tube is provided with a discharge baffle for blocking the discharge port, and the discharge baffle is detachably connected to the lifting tube.

[0013] Furthermore, one end of the discharge baffle close to the lifting auger is tangent to the inner wall of the lifting pipe; and the discharge baffle is provided with a sealing ring.

[0014] Furthermore, there are several circulating discharge ports, and each of the circulating discharge ports is evenly distributed around the lifting pipe. The horizontal height of the bottom surface of each circulating discharge port close to the end of the lifting auger is higher than the horizontal height of the bottom surface of the circulating discharge port away from the end of the lifting auger.

[0015] The working principle and beneficial effects of the present invention are: The technical solution of the present invention adopts a lifting mechanism provided inside the drying tank, so that the powder located at the bottom of the drying tank can be lifted to the top of the drying tank through the lifting mechanism, and so on. This can ensure that the powder in the drying tank is always at the top of the drying tank (the top of the powder pile), thereby ensuring that the powder can be dried evenly, thereby ensuring the powder drying effect.

[0016] Specifically, the lifting mechanism in the present invention mainly includes a lifting pipe, a lifting auger, and a driving motor. The lifting auger is rotatably connected to the lifting pipe, and the lifting auger itself is linked to the output shaft of the driving motor. The lifting pipe is provided with a circulation inlet and a circulation outlet. The circulation inlet is located at the bottom of the drying tank, and the circulation outlet is located at the top of the drying tank. In this way, during the rotation of the lifting auger, the powder (seasoning) can be continuously driven along the circulation inlet to the circulation outlet, and discharged from the circulation outlet, thereby realizing the circulation movement of the powder.

[0020] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0022] like Figure 1As shown, this embodiment proposes a solid seasoning drying device, including a drying tank 1. The drying tank 1 in this embodiment is preferably a drying mechanism that dries by hot air, that is, this embodiment quickly removes moisture by forced circulation of hot air, thereby completing the drying of the seasoning. The specific method of drying the seasoning should depend on the actual equipment model selected, and will not be described in detail in this embodiment.

[0023] The drying tank 1 is provided with a feed port 11 and a discharge port 12 to ensure that the staff can add the seasoning to be dried into the drying tank 1 and take the dried seasoning out of the drying tank 1. The feed port 11 is equipped with a feed hopper to facilitate the adding work of this embodiment.

[0024] The drying tank 1 is provided with a lifting mechanism 2 for lifting the seasoning, that is, the seasoning in the drying tank 1 can continuously change its horizontal height position. Specifically, the lifting mechanism 2 mainly includes a lifting pipe 21, a lifting auger 22, and a drive motor 23 for driving the lifting auger 22 to rotate. The lifting auger 22 is rotatably connected to the lifting pipe 21, and the lifting auger 22 itself is linked to the output shaft of the drive motor 23. The drive motor 23 is fixedly connected to the drying tank 1 to ensure that the drive motor 23 can stably provide driving force; the lifting pipe 21 is provided with a circulating feed port 211 and a circulating discharge port 212. The circulating feed port 211 is located at the bottom of the drying tank 1, and the circulating discharge port 212 is located at the bottom of the drying tank 1. 212 is located at the top of the drying tank 1, that is, under the action of the lifting auger 22, the seasoning in the drying tank 1 can enter the lifting tube 21 along the circulation inlet 211, and then move along the axial direction of the lifting tube 21 until it is discharged from the circulation outlet 212, and fall back into the drying tank 1 under the action of gravity, so that the seasoning at the bottom of the accumulated powder moves to the top of the accumulated powder in turn, and this cycle is repeated, so that the seasoning inside the drying tank 1 can be evenly dried, thereby ensuring the drying effect of this embodiment.

[0025] At the same time, if Figure 4 As shown, the drying tank 1 in this embodiment is further provided with a stirring mechanism 3. The stirring operation of the stirring mechanism 3 causes the material in the drying tank 1 to flow, thereby breaking the static air layer (boundary layer) on the surface of the material, enhancing the contact efficiency between the hot air and the material, accelerating the diffusion of moisture, and improving the material drying efficiency. Moreover, since each material particle is in a state of continuous tumbling and flow, all surfaces of the material particles are exposed to the hot air in turn, further reducing the probability of uneven drying.

[0026] The central axis of the lifting tube 21 coincides with the rotation axis of the stirring mechanism 3 , thereby conveniently avoiding interference between the stirring mechanism 3 and the lifting tube 21 during rotation.

[0027] Specifically, such as Figure 4 、 Figure 6As shown, the stirring mechanism 3 includes a stirring paddle 31 and an interfering fluid 32, wherein the stirring paddle 31 mainly includes a driving ring 311, a connecting ring column 312, and a plurality of stirring blades 313. The driving ring 311 and the connecting ring column 312 are both rotatably connected to the lifting tube 21. The annular structure of the driving ring 311 and the connecting ring column 312 can effectively avoid the structural structure of the lifting tube 21, thereby avoiding mutual interference between the stirring mechanism 3 and the lifting mechanism 2, and ensuring the feasibility of this embodiment.

[0028] A first connecting rod 314 is provided between each stirring blade 313 and the driving ring 311 for fixedly connecting the two, and each stirring blade 313 is fixedly connected to the connecting ring column 312. That is, when the driving ring 311 rotates, it drives each stirring blade 313 to rotate, and then stirs the material with the help of the movement of the stirring blade 313 to complete the stirring of the material. Moreover, due to the fixed connection between each stirring blade 313 and the connecting ring column 312, when one part of the stirring paddle 31 moves, the entire structure of the stirring paddle 31 will also produce relative movement. And as the overall structure of the stirring paddle 31 rotates, it can also drive the material in the drying tank 1 to quickly approach the circulation inlet 211, so that the material quickly fills the lifting tube 21, ensuring the continuity of the up and down circulation movement of the material. Preferably, one end of each stirring blade 313 close to the bottom of the drying tank 1 (the discharge port 12) abuts against the bottom of the drying tank 1, and the circulation inlet 211 is opened below the stirring blade 313, and a guiding surface is provided between the circulation inlet 211 and the drying tank 1, thereby ensuring that as the stirring paddle 31 moves, the material in the drying tank 1 can be accurately swept into the circulation inlet 211, ensuring that all the powder in the drying tank 1 can enter the lifting mechanism 2 for lifting and lowering circulation; The lifting tube 21 is located in the inner ring of the connecting ring column 312. By virtue of the rotational connection between the connecting ring column 312 and the lifting tube 21, the lifting tube 21 can provide a certain area of ​​contact surface for the connecting ring column 312, thereby supporting and stabilizing the stirring paddle 31, making the rotational movement of the stirring paddle 31 more stable. The circulating discharge port 212 is located between the connecting ring column 312 and the driving ring 311 to prevent the circulating discharge port 212 from being blocked by the connecting ring column 312 or the driving ring 311, ensuring that the lifting mechanism 2 can circulate the material normally (discharge the seasoning from the lifting tube 21).

[0029] Preferably, each first connecting rod 314 is tiltedly arranged between the drive ring 311 and each stirring blade 313, which can not only prevent each first connecting rod 314 from blocking the circulation discharge port 212 after moving a certain distance, but also can use the design of its tilt angle to convert part of the torque into axial and radial components rather than pure torsional force, so that the load can be dispersed in multiple directions, reducing the direct impact of the torque on the overall structure of the stirring paddle 31, and effectively ensuring the overall structural strength and stability of the stirring paddle 31.

[0030] In order to enable each disrupting body 32 to cooperate with the stirring paddle 31, a second connecting rod 315 for fixedly connecting the two is provided between each stirring blade 313 and the connecting ring column 312. Each disrupting body 32 is rotatably connected to each second connecting rod 315. That is, the second connecting rod 315 not only serves to fixedly connect the stirring blade 313 and the connecting ring column 312, but also provides a point on the stirring paddle 31 for the stirring paddle 31 to be installed.

[0031] The rotation axis of each disturbing body 32 is perpendicular to the rotation axis of the stirring paddle 31 , so as to avoid the flow and mixing path of the material being too single under the stirring action of the stirring mechanism 3 .

[0032] Specifically, each disruptor body 32 in this embodiment mainly includes a rotating ring column 321 and, if there are disruptor blades 322, the rotating ring column 321 is rotatably connected to the second connecting rod 315, and each disruptor blade 322 is fixedly connected to the rotating ring column 321 and evenly distributed around the circumference of the rotating ring column 321. Each disruptor blade 322 is preferably fixed to the rotating ring column 321 by welding to the rotating ring column 321 to ensure the connection strength between the two.

[0033] As the stirring paddle 31 rotates, the disturbing bodies 32 on the stirring paddle 31 will rotate together due to the reaction force generated by the material in contact with it, actively performing a disturbing flow operation. Since the rotation axis of each disturbing body 32 is perpendicular to the rotation axis of the stirring paddle 31, the horizontally rotating disturbing body 32 will disrupt the flow of the material in the radial direction of the stirring paddle 31, thereby generating multiple turbulent vortices inside the drying tank 1, further optimizing the powder mixing operation; and breaking up sticky material clumps when the seasoning particles have too high a moisture content and stick to each other.

[0034] A drainage ring 213 is provided on the lifting pipe 21, and the drainage ring 213 is located between the circulation discharge port 212 and the connecting ring column 312. The outer ring diameter of the drainage ring 213 is larger than the outer ring diameter of the connecting ring column 312, that is, the existence of the drainage ring 213 plays a role of physical drainage, effectively preventing the material from falling on the end face of the connecting ring column 312 when being discharged from the circulation discharge port 212, causing the material to accumulate on the end face of the connecting ring column 312.

[0035] Preferably, the longitudinal section of the drainage ring 213 is an isosceles triangle structure. In this way, not only can the material particles falling on the drainage ring 213 be guided by the structure of the inclined surface of the drainage ring 213 and the influence of gravity to ensure that they can fall to the bottom of the drying tank 1, but the structural strength of the drainage ring 213 itself can also be ensured by the stable and firm characteristics of the triangular structure.

[0036] Similarly, the end of each stirring blade 313 connected to the first connecting rod 314 (the end of the stirring blade 313 close to the feed inlet 11 ) is also an isosceles triangle structure to prevent falling materials from accumulating on the end surface of the stirring blade 313 .

[0037] like Figures 3 and 4 As shown, the drive ring 311 and the lifting auger 22 in this embodiment are linked to each other, thereby avoiding the existence of the stirring mechanism 3, and requiring additional drive elements in this embodiment, thereby effectively reducing the operating cost of this embodiment.

[0038] Preferably, a linkage external gear is provided on the lifting auger 22, and a linkage internal gear is provided on the drive ring 311, and the linkage external gear and the linkage internal gear are engaged with each other. In this way, the linkage relationship between the lifting auger 22 and the drive ring 311 can be confirmed by simply fixing the drive motor 23 after ensuring that the linkage external gear and the linkage internal gear are engaged. There is no need to set up an additional fixing structure for fixing the two, which facilitates the use of this embodiment.

[0039] like Figure 2 、 Figure 4 As shown, the lifting pipe 21 in this embodiment passes through the drying tank 1 itself, and the discharge port 12 is located at the end of the lifting pipe 21 away from the driving motor 23, and is symmetrically distributed on both sides of the lifting pipe 21 with the circulating feed port 211. The lifting pipe 21 is provided with a discharge baffle 4 for blocking the discharge port 12 to ensure that when the present embodiment is in working state, the material will not leak out from the discharge port 12; and to avoid the existence of the discharge port 12 destroying the conveying path structure of the lifting pipe 21, causing material leakage; and because the discharge port 12 is also opened on the lifting pipe 21, the direction of the lifting auger 22 can be used to rotate to achieve control of the amount of discharged material, thereby improving the accuracy of the discharge work of this embodiment.

[0040] The discharge baffle 4 is detachably connected to the lifting tube 21, ensuring that when the material in the drying tank 1 needs to be taken out, the discharge baffle 4 can be removed from this embodiment to proceed with the discharge operation. Preferably, the discharge baffle 4 is provided with a plurality of fixed matching holes, and the lifting tube 21 is provided with a plurality of connecting holes. Connectors are provided between each of the fixed matching holes and the connecting holes, and the connecting members are threadedly connected to the fixed matching holes and the connecting holes. That is, the detachable connection between the discharge baffle 4 and the lifting tube 21 is achieved through the threaded connection between each of the connecting members and the connecting holes and the fixed matching holes, which not only ensures the reliability of the connection, but also ensures the convenience of disassembly and assembly of the discharge baffle 4.

[0041] And because the circulation inlet 211 and the discharge port 12 are symmetrically distributed on both sides of the lifting pipe 21, when the circulation inlet 211 is blocked, the discharge port 12 can be opened and an external stick-like structure (such as a broom, etc.) can be used to poke the circulation inlet 211 to destroy the blockage and ensure the normal material conveying path of the lifting mechanism 2.

[0042] If necessary, during the discharge process, a conveying mechanism such as a belt conveyor should be set below the discharge port 12 to directly transport the dried seasoning away from the bottom of this embodiment and send it to the next processing equipment. The specific conveying mechanism to be selected should be determined according to the actual production line situation and will not be described in detail in this embodiment.

[0043] One end of the discharge baffle 4 close to the lifting auger 22 is tangent to the inner wall of the lifting tube 21, that is, a gap is avoided between the discharge baffle 4 and the lifting tube 21 (material entering the gap will leave the conveying range of the lifting auger 22, resulting in a conveying and drying dead corner in this embodiment), ensuring the drying effect of this embodiment.

[0044] The discharge baffle 4 is provided with a sealing ring 5, which is preferably made of elastic materials such as silicone. That is, during the installation of the discharge baffle 4, the sealing ring 5 is deformed by the force applied to it to ensure the sealing between the discharge baffle 4 and the lifting tube 21 and cover the connection gap between the discharge baffle 4 and the lifting tube 21.

[0045] like Figure 5 As shown, there are several circulating discharge ports 212, and each circulating discharge port 212 is evenly distributed around the lifting pipe 21. That is, through the redundant design of the circulating discharge port 212, not only the risk of abnormal discharge from the lifting pipe 21 is reduced, but also the lifting pipe 21 can realize multi-angle discharge, effectively avoiding the occurrence of deviation flow or local accumulation caused by unilateral discharge.

[0046] The horizontal height of the bottom surface of each circulation discharge port 212 close to one end of the lifting auger 22 is higher than the horizontal height of the bottom surface of the circulation discharge port 212 away from the one end of the lifting auger 22, that is, the bottom surface of each circulation discharge port 212 is inclined so that the seasoning at the moving circulation discharge port 212 can be quickly discharged from the lifting pipe 21.

[0047] The same or similar numbers in the drawings of this embodiment correspond to the same or similar parts; in the description of this application, it should be understood that if the terms "upper", "lower", "left", "right", etc. indicate an orientation or position relationship, they are based on the orientation or position relationship shown in the drawings. This is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0048] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
