Description

Technical Field

[0001] This invention relates to the field of wolfberry pretreatment technology, and in particular to a wolfberry pretreatment device based on wolfberry paste production. Background Technology

[0002] Goji berry paste is a traditional tonic made from goji berries through boiling and concentration. It is convenient to consume and has a high absorption rate of its active ingredients. In the production process of goji berry paste, raw material pretreatment is a crucial step in determining product quality, mainly including two processes: washing and drying. Washing removes mud, dust, and some microorganisms from the surface of the goji berries, while drying removes some moisture from the surface and interior of the goji berries, creating conditions for the subsequent boiling process.

[0003] During pretreatment, the goji berries are thoroughly contacted with water using a washing device to remove surface impurities. After washing, the goji berries are transferred to a drying device via a conveyor belt for hot air drying.

[0004] However, existing goji berry washing and drying processes lack an effective moisture transition step. After washing, the surface of the goji berries is covered with a large amount of free water, resulting in excessively high surface moisture content when directly introduced into the drying equipment. In the initial drying stage, the evaporation of this large amount of water requires significant heat energy, leading to prolonged drying time and high energy consumption. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a goji berry pretreatment device based on goji berry paste production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A goji berry pretreatment device based on goji berry paste production includes a machine body, on which a washing tank, a draining assembly and a drying chamber are sequentially arranged, and materials are conveyed between them by a conveyor belt. The drain assembly includes a drain cylinder, a conveying shaft is rotatably arranged inside the drain cylinder, a spiral blade for conveying materials is arranged on the conveying shaft, hook plates for tumbling materials are arranged on both sides of the conveying shaft, and an air seat for blowing air toward the materials is arranged on one side of the drain cylinder. The conveyor shaft rotates via a driven shaft, which in turn rotates via a drive shaft, and the drive shaft is used to drive the transmission belt to rotate. Multiple synchronously rotating annular push blocks are sleeved on the driven shaft. The annular push blocks are provided with a flat surface, a transition surface and an arc surface. The push plate moves vertically back and forth through the rotation of the annular push blocks to repeatedly compress and release the bellows to supply air to the air seat.

[0007] In addition, a preferred structure is that the draining tube is fixedly installed inside the machine body, one end of the draining tube is provided with a feed inlet, the other end is provided with a discharge outlet, and a water leakage mesh plate is provided at the bottom of the draining tube.

[0008] In addition, a preferred structure is that an inclined conveyor belt for conveying materials to the feed inlet is provided on the machine body behind the washing tank, the inclined conveyor belt is driven by a drive shaft, and a flat conveyor belt for conveying materials to the drying chamber is provided on the machine body below the discharge outlet.

[0009] Furthermore, in a preferred configuration, the driven shaft is connected to the driving shaft via a sprocket and chain transmission mechanism, and the conveying shaft is connected to the driven shaft via a worm gear transmission mechanism.

[0010] In addition, a preferred structure is that an air seat is installed on one side of the drain cylinder, a distribution chamber is opened inside the air seat, multiple one-way valves communicating with the distribution chamber are installed on the outside of the air seat, and multiple air blowing ports communicating with the distribution chamber are opened on the air seat.

[0011] In addition, a preferred structure is that the body has multiple top plates fixedly connected to the body above the driven shaft, each top plate is equipped with an air nozzle, and each air nozzle is connected to a one-way valve through an air pipe.

[0012] In addition, a preferred structure is that the bottom of the top plate is provided with a bellows, the bottom of the bellows is fixedly provided with a base, a push plate is movably provided below the base, multiple through holes are vertically opened on the base, and a sealing element is provided for each corresponding through hole on the push plate.

[0013] In addition, a preferred structure is that multiple guide columns are fixedly and vertically arranged at the bottom of the top plate, each guide column has a lower side block fixedly arranged on its outer side, and each guide column has an anti-fall plate fixedly arranged at its bottom.

[0014] In addition, a preferred structure is that an upper side block is adapted to be provided on each of the lower side blocks on the base, and an upper guide cavity and a lower guide cavity are respectively opened on the base and the push plate corresponding to the guide post.

[0015] In addition, a preferred structure is that an anti-lock plate is fixedly provided on one side of each push plate, and each anti-lock plate is provided with a slope. An anti-lock post is provided on the surface of the driven shaft through a fixed seat, and the anti-lock post is adapted to the anti-lock plate.

[0016] The beneficial effects of this invention are as follows: the washing tank and drying chamber inside the machine can realize the washing and drying of goji berries in the pretreatment process. By setting a drain tube between the washing and drying processes and using the drive shaft of the inclined conveyor belt to drive the driven shaft and the conveyor shaft to rotate, the goji berries can be pre-drained before the drying process, which reduces the surface moisture content of the goji berries before they enter the drying chamber, shortens the subsequent drying time, and reduces energy consumption.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] See Figure 1-2 The machine body 1 is provided with a washing tank 11, a draining assembly and a drying chamber 14 in sequence. An inclined conveyor belt 12 for conveying materials to the feed inlet 51 is provided behind the washing tank 11 on the machine body 1, and a flat conveyor belt 13 for conveying materials to the drying chamber 14 is provided below the discharge outlet 52 on the machine body 1.

[0021] In the pretreatment of goji berries, the berries are first poured into the washing tank 11. After washing, they are conveyed to the draining assembly via the inclined conveyor belt 12 for draining. After draining, the berries fall through the discharge port 52 onto the flat conveyor belt 13, and finally pass through the drying chamber 14 to achieve drying. It is worth noting that the washing tank 11, inclined conveyor belt 12, flat conveyor belt 13, and drying chamber 14 are all existing technologies, and therefore will not be described in detail.

[0022] See Figure 2-5 The inclined conveyor belt 12 is driven by the drive shaft 2, which is driven by a motor. The driven shaft 3 is connected to the drive shaft 2 via a sprocket and chain transmission mechanism 21, and the conveying shaft 4 is connected to the driven shaft 3 via a worm gear transmission mechanism 22. The inclined conveyor belt 12 is driven by the drive shaft 2.

[0023] In this way, the rotation of the drive shaft 2 can drive the inclined conveyor belt 12 to rotate, and in turn drive the driven shaft 3 and the conveyor shaft 4 to rotate. All of the above are existing technologies, and therefore will not be elaborated further.

[0024] See Figure 3-13Multiple synchronously rotating annular push blocks 31 are sleeved on the driven shaft 3. Each annular push block 31 has a flat surface 311, a transition surface 312, and an arc surface 313. When the flat surface 311 contacts the push plate 65, the push plate 65 is at its lowest position due to gravity. When the transition surface 312 contacts the push plate 65, the push plate 65 is continuously pushed upwards. When the arc surface 313 contacts the push plate 65, the push plate 65 is at its highest position.

[0025] The machine body 1 contains multiple top plates 6 fixedly connected to the machine body 1, located above the driven shaft 3. Each top plate 6 is equipped with an air nozzle 61, and each air nozzle 61 is connected to a one-way valve 541 via an air pipe. This allows the gas ejected from the air nozzle 61 to be delivered to the air seat 54 through the one-way valve 541, thereby supplying air to the air seat 54. In practical applications, multiple air supply components can be set up, ensuring that there is a certain angle between the annular push blocks 31 between them, so that the air supply components can alternately supply air to the air seat 54.

[0026] The top plate 6 has a bellows 63 at its bottom, a base 64 is fixedly mounted at the bottom of the bellows 63, and a push plate 65 is movably mounted below the base 64. The base 64 has multiple through holes 643 vertically extending through it, and the push plate 65 is fitted with a sealing element 653 corresponding to each through hole 643.

[0027] When the push plate 65 moves upward, it pushes the base 64 to move upward simultaneously, and at this time, the seals 653 block the through holes 643. At this time, the movement of the base 64 compresses the bellows 63, thereby allowing the gas inside the bellows 63 to be ejected from the air nozzle 61.

[0028] When the annular pusher 31 stops pushing the pusher plate 65, the pusher plate 65 and the base 64 fall synchronously under gravity. At this time, the bellows 63 is stretched, and the base 64 and the pusher plate 65 separate. The seal 653 no longer blocks the through hole 643, and new gas can enter the bellows 63 through the through hole 643.

[0029] The top plate 6 has multiple guide posts 62 fixed vertically downward at its bottom, and the base 64 and push plate 65 have corresponding upper guide cavities 642 and lower guide cavities 652 respectively. The guide posts 62 enable the base 64 and push plate 65 to move vertically and stably.

[0030] Each guide post 62 is fixedly equipped with an anti-detachment plate 622 at its bottom to prevent the push plate 65 from falling off the guide post 62.

[0031] Each guide post 62 has a lower side block 621 fixedly installed on its outer side, and an upper side block 641 is fitted on the base 64 to correspond to the lower side block 621. The support of the upper side block 641 by the lower side block 621 ensures that when the base 64 and the push plate 65 are both moved to the bottom, there is a certain gap between the base 64 and the push plate 65 to ensure smooth ventilation of the through hole 643.

[0032] Among them, an anti-lock plate 651 is fixedly installed on one side of the push plate 65. The anti-lock plate 651 is provided with a slope. The surface of the driven shaft 3 is provided with an anti-lock post 321 through the fixing seat 32. The anti-lock post 321 is adapted to the anti-lock plate 651, and each anti-lock plate 651 corresponds to one anti-lock post 321.

[0033] When the push plate 65 falls to the bottom, it should automatically disengage from the base 64 under normal circumstances due to its own weight. However, occasionally, the push plate 65 may fail to disengage due to the negative pressure inside the bellows 63 or the friction of the seal 653.

[0034] At this time, as the driven shaft 3 rotates, the anti-locking pin 321 can be rotated to the slope on the anti-locking plate 651. Then, the connection between the push plate 65 and the base 64 can be released by the push of the anti-locking pin 321 on the anti-locking plate 651, so as to ensure that the through hole 643 can be normally air-intake.

[0035] See Figure 14-17 The drain cylinder 5 is fixedly installed inside the machine body 1. One end of the drain cylinder 5 is provided with a feed inlet 51 and the other end is provided with a discharge outlet 52. A water-permeable mesh plate 53 is provided at the bottom of the drain cylinder 5. The water-permeable mesh plate 53 is existing technology, and its opening is small, which can only ensure the water flow through without affecting the normal movement of the goji berries.

[0036] The drain cylinder 5 has an air seat 54 installed on one side, and a distribution chamber 542 is opened inside the air seat 54. Multiple one-way valves 541 connected to the distribution chamber 542 are installed on the outside of the air seat 54. The one-way valves 541 ensure that gas can only enter the air seat 54 and will not leak out.

[0037] The air seat 54 has multiple air inlets 543 that communicate with the distribution chamber 542. Gas can enter the distribution chamber 542 through the one-way valve 541 for distribution, and then be blown into the drain cylinder 5 through the air inlets 543.

[0038] The conveyor shaft 4 is equipped with spiral blades 41 for conveying materials, and hook plates 42 for tumbling materials are located on both sides of the conveyor shaft 4. During the rotation of the conveyor shaft 4, the spiral blades 41 facilitate the conveying of materials within the drain cylinder 5. The hook plates 42 cause the materials to be continuously lifted and tumbled by the hook plates 42 as the conveyor shaft 4 rotates, and then fall from the top of the drain cylinder 5 through the hook plates 42, thus achieving the purpose of draining the materials.

[0039] In this embodiment, during the pretreatment of goji berries, the user simply pours the goji berries into the washing tank 11, where the water flow cleans them. The goji berries are then conveyed to the feed inlet 51 via the inclined conveyor belt 12, where they are drained by the draining assembly. After draining, the goji berries fall onto the flat conveyor belt 13 through the discharge outlet 52, and finally, they are dried in the drying chamber 14, thus completing the cleaning and drying processes in the pretreatment.

[0040] Furthermore, the inclined conveyor belt 12 is driven by the drive shaft 2, the driven shaft 3 is connected to the drive shaft 2 via a sprocket and chain transmission mechanism 21, and the conveying shaft 4 is connected to the driven shaft 3 via a worm gear transmission mechanism 22. This ensures that when the inclined conveyor belt 12 is running, the driven shaft 3 and the conveying shaft 4 are also driven to rotate.

[0041] During the rotation of the conveyor shaft 4, the spiral blades 41 transport the material in the drain cylinder 5 from the inlet 51 to the outlet 52. The hook plate 42 lifts and flips the material during transport, allowing it to fall from a height within the drain cylinder 5. As the material falls under gravity, the airflow from the air seat 54 further drains the material, significantly removing surface moisture. The drained water then flows out through the drain screen 53.

[0042] During the rotation of the driven shaft 3, it drives the annular push block 31 to rotate synchronously. The annular push block 31 is provided with a flat surface 311, a transition surface 312, and an arc surface 313. When the flat surface 311 contacts the push plate 65, the push plate 65 is at its lowest position due to gravity. When the transition surface 312 contacts the push plate 65, the push plate 65 is continuously pushed upward. When the arc surface 313 contacts the push plate 65, the push plate 65 is at its highest position.

[0043] When the push plate 65 moves upward, it pushes the base 64 upward simultaneously, and at this time, the seals 653 block the through holes 643. The movement of the base 64 compresses the bellows 63, thus expelling the gas inside the bellows 63 from the air nozzle 61. The gas then passes through the air pipe and one-way valve 541 before entering the air seat 54, and finally is sprayed onto the material falling from the drain cylinder 5 after being lifted by the hook plate 42.

[0044] When the plane 311 of the annular pusher 31 faces the pusher plate 65, it stops pushing the pusher plate 65 upward. The pusher plate 65 and the base 64 fall synchronously under gravity. At this time, the bellows 63 is stretched, and the base 64 and the pusher plate 65 separate. The seal 653 no longer blocks the through hole 643. At this time, new gas can enter the bellows 63 through the through hole 643, thereby realizing the next jet cycle.

[0045] Furthermore, the guide post 62 is provided with a lower side block 621 and an anti-drop plate 622, so that the base 64 and the push plate 65 fall to different heights at the bottom, so that when they fall to the bottom, the base 64 and the push plate 65 can be automatically separated.

[0046] When the push plate 65 falls to the bottom, it should automatically disengage from the base 64 under normal circumstances due to its own weight. However, occasionally, the push plate 65 may fail to disengage due to the negative pressure inside the bellows 63 or the friction of the seal 653.

[0047] At this time, as the driven shaft 3 rotates, the anti-locking pin 321 can be rotated to the slope on the anti-locking plate 651. Then, the connection between the push plate 65 and the base 64 can be released by the push of the anti-locking pin 321 on the anti-locking plate 651, so as to ensure that the through hole 643 can be normally air-intake.

[0048] Furthermore, in other embodiments, a jacket can be provided in the inner wall of the drain cylinder 5, and a gas or liquid heat exchange channel can be provided in the jacket. In this way, the temperature inside the drain cylinder 5 can be maintained through heat exchange, so as to further enhance the draining effect on the goji berries.

[0049] In this invention, the washing tank 11 and drying chamber 14 provided in the machine body 1 can realize the washing and drying of goji berries in the pretreatment process. By setting up a drain tube 5 between the washing and drying processes, and using the drive shaft 2 of the inclined conveyor belt 12 to drive the driven shaft 3 and the conveyor shaft 4 to rotate, the goji berries can be pre-drained before the drying process, which reduces the surface moisture content of the goji berries before entering the drying chamber 14, shortens the subsequent drying time, and reduces energy consumption.

[0050] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
