[0039] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0040] The embodiment of the present invention provides an agricultural product processing and drying device, such as Figure 1-16 As shown, the agricultural product processing and drying device includes: a drying box 1, a discharge box 2 and a chili paste storage barrel 5. A through port 3 is opened on one side of the drying box 1. The discharge box 2 is fixedly installed on the side of the through port 3 of the drying box 1. The bottom of the discharge box 2 away from the drying box 1 has a discharge port 4 for discharging the dried chili particles. The chili paste storage barrel 5 is fixedly installed on the top of the drying box 1, and is used to discharge the chili paste into the drying box 1 for drying; a drying conveyor belt 6 is installed in the drying box 1 for conveying chili paste, and the same discharge conveyor belt 7 is installed in the drying box 1 and the discharge box 2. The discharge conveyor belt 7 is located below the discharge side of the drying conveyor belt 6, and is used to receive the dried chili particles on the drying conveyor belt 6. The drying conveyor belt 6 and the discharge conveyor belt 7 rotate synchronously. Skirts 8 are fixedly installed on both sides of the conveyor belt 6 to shield the chili paste being conveyed; a closed material baffle plate 9, which is fixedly installed in the drying box 1, and is located below the drying conveyor belt 6 to close the excess space in the drying box 1, one end of the closed material baffle plate 9 extends to the top of the material receiving end of the discharge conveyor belt 7 and contacts with the upper surface of the discharge conveyor belt 7 to prevent material from being scattered; an infrared drying radiator 10, which is fixedly installed on the top inner wall of the drying box 1, and an infrared radiator 11 is installed at the bottom of the infrared drying radiator 10 to dry the chili paste transmitted through the drying conveyor belt 6; an air spiciness removal mechanism, which is installed on the drying box 1 and the discharge box 2 to remove the spiciness of the spicy air generated by drying.

[0041] In this embodiment, first, the chili paste is poured into the chili paste storage barrel 5. Then, the drying conveyor belt 6 and the discharge conveyor belt 7 are started to ensure that the two rotate synchronously. At this time, the chili paste flows out of the storage barrel 5 and is evenly applied to the drying conveyor belt 6.

[0042] As the drying conveyor belt 6 moves, the chili paste enters the drying box 1. The infrared drying radiator 10 dries the chili paste efficiently through the infrared radiating element 11 at its bottom. At the same time, the skirt belt 8 blocks the transmitted chili paste to prevent it from splashing. The closed baffle plate 9 closes the extra space in the drying box 1, reduces heat loss, and ensures the stability of the drying environment.

[0043] The dried chili particles move to the discharge end along the drying conveyor belt 6, at which time they fall on the discharge conveyor belt 7 and are transferred to the discharge box 2. The dried chili particles are discharged at the discharge port 4 of the discharge box 2. At the same time, the air spiciness removal mechanism is started to remove the spiciness of the air generated during the drying process to ensure a safe and comfortable working environment.

[0044] This solution uses precise heating of the infrared drying radiator 10, and this device significantly improves the drying efficiency of the chili paste and shortens the production cycle.

[0045] The design of the skirt belt 8 and the closed baffle plate 9 effectively prevents the chili paste from splashing and contaminating during the drying process, thereby ensuring the cleanliness and quality of the product.

[0046] The application of air spiciness removal mechanism effectively reduces the diffusion of spiciness air during the drying process, reduces the irritation and harm to production personnel, and improves the working environment.

[0047] This device reduces energy consumption and environmental pollution through efficient and environmentally friendly drying methods, conforms to the concept of green production, and helps promote the sustainable development of the agricultural product processing industry.

[0048] In a further preferred embodiment of the present invention, the air spiciness removal mechanism includes an air inlet pipe 12, an air outlet pipe 13, a drainage shell 14, a fan blade assembly 15, an aeration main pipe 16, a spiciness removal aeration box 17, an aeration branch pipe 18, a conduction main pipe 19 and a conduction branch pipe 20, the air inlet pipe 12 and the air outlet pipe 13 are fixedly mounted on the top of the drying box 1, the drainage shell 14 is mounted on the exhaust end of the air outlet pipe 13, the fan blade assembly 15 is mounted on the drainage shell 14, the fan blade assembly 15 rotates synchronously with the drying conveyor belt 6 and the discharge conveyor belt 7, and the aeration The main pipe 16 is installed on the drainage shell 14, the spicy aeration box 17 is fixedly installed on the top of the drying box 1, the aeration branch pipe 18 is installed on the aeration main pipe 16, the exhaust end of the aeration branch pipe 18 extends into the spicy aeration box 17, the spicy aeration box 17 is filled with a solution, and a discharge port is opened on the top of the spicy aeration box 17, the conduction main pipe 19 is installed on the air outlet pipe 13, the conduction main pipe 19 extends to the top of the discharge box 2, and the conduction branch pipe 20 is fixedly installed on the top of the discharge box 2 and is connected to the conduction main pipe 19.

[0049] In this embodiment, when the drying conveyor belt 6 and the discharge conveyor belt 7 start to rotate synchronously, the fan blade assembly 15 is also started. The fan blade assembly 15 is connected to the air outlet pipe 13 through the drainage shell 14, and uses the airflow power generated inside the drying box 1 to achieve automatic rotation. The conduction main pipe 19 is provided with a check valve, so that the hot air in the discharge box 2 can also flow into the air outlet pipe 13.

[0050] The air containing spicy smell enters the drying box 1 from the air inlet pipe 12. After the drying process, the spicy air is sucked into the fan blade assembly 15 and distributed to the aeration branch pipe 18 through the aeration main pipe 16. The aeration branch pipe 18 guides the spicy air into the aeration box 17 for removing spicy smell, and reacts with the solution therein to effectively remove the spicy smell.

[0051] The air treated with heat removal is discharged through the discharge port at the top of the heat removal aeration box 17.

[0052] The synchronous rotation design of the fan blade assembly 15, the drying conveyor belt 6 and the discharge conveyor belt 7 fully utilizes the airflow power during the drying process without additional energy consumption, thus reflecting the design concept of energy saving and environmental protection.

[0053] In a further preferred embodiment of the present invention, a raking plate 21 is fixedly installed at the bottom of the infrared drying radiator 10, and the raking plate 21 extends to the top of the drying conveyor belt 6 and is provided with a plurality of raking openings 22 for raking the transmitted chili paste. The raking plate 21 and the infrared radiator 11 are both provided with a plurality of raking openings 22 and are staggered.

[0054] In this embodiment, when the drying conveyor belt 6 starts to rotate, the chili paste is evenly spread on the conveyor belt. At the same time, the infrared drying radiator 10 is started, and the infrared radiating element 11 at the bottom thereof starts to emit infrared radiation to heat and dry the chili paste.

[0055] The raking plate 21 raks the transferred chili paste through a plurality of raking openings 22. This design not only helps to evenly distribute the chili paste, but also increases its contact area with infrared radiation, thereby improving drying efficiency. At the same time, since the raking plate 21 and the infrared radiation element 11 are staggered, it can be ensured that the chili paste is continuously and evenly dried during the transfer process.

[0056] After a period of drying, the chili paste gradually loses moisture and becomes dry chili particles. At this time, the drying conveyor belt 6 continues to transmit the chili particles to the discharge end to complete the whole drying process.

[0057] Through the design of the raking plate 21, the chili paste is evenly raked during the transmission process, increasing the contact area with the infrared radiation, thereby improving the drying efficiency. At the same time, the staggered raking plates 21 and infrared radiation elements 11 ensure that the chili paste is continuously and evenly dried during the transmission process, further improving the drying effect.

[0058] The use of the rake plate 21 not only helps to evenly distribute the chili paste, but also prevents it from agglomerating or sticking during the drying process, thereby optimizing the drying quality. In addition, since the infrared radiation emitted by the infrared radiator 11 is penetrating, it can penetrate deep into the chili paste for drying, so the dried chili particles are looser and more uniform.

[0059] In a further preferred embodiment of the present invention, a hanging plate 23 is fixedly installed on one side of the drying box 1 located at the through port 3, and the hanging plate 23 extends to above the discharge side of the drying conveyor belt 6. A soft stopper 24 is fixedly installed on the bottom of the hanging plate 23, and the soft stopper 24 is in contact with the drying conveyor belt 6.

[0060] In this embodiment, a hanging plate 23 is fixedly installed on one side of the through opening 3 of the drying box 1, ensuring that it extends above the discharge side of the drying conveyor belt 6. A soft stopper 24 is fixedly installed at the bottom of the hanging plate 23, so that the soft stopper 24 is in close contact with the surface of the drying conveyor belt 6, but does not generate excessive resistance, so as to ensure the smooth operation of the conveyor belt.

[0061] When the drying conveyor belt 6 starts to run, the chili paste and other materials are evenly spread on the conveyor belt and dried by the infrared drying radiator 10 or other drying devices in the drying box 1. During the transmission process, the soft stopper 24 plays a certain blocking and guiding role, preventing the material from falling from the edge of the conveyor belt during the transmission process, and also ensuring that the material can be smoothly transmitted to the discharge end according to the predetermined path.

[0062] The material after drying gradually reaches the discharge end along with the operation of the drying conveyor belt 6. At this time, due to the blocking effect of the soft stop 24, the material can be neatly piled up on the discharge side of the conveyor belt, which is convenient for subsequent collection and processing.

[0063] In a further preferred embodiment of the present invention, a stabilizing frame 25 is fixedly installed on the top of the drying box 1 , and the input shaft of the fan blade assembly 15 extends outside the drainage shell 14 and is rotatably connected to the stabilizing frame 25 .

[0064] In this embodiment, the stabilizing frame 25 is fixedly installed on the top of the drying box 1. Its main function is to provide stable support for the input shaft of the fan blade assembly 15. The input shaft of the fan blade assembly 15 extends to the outside of the drainage shell 14 and is rotationally connected to the stabilizing frame 25.

[0065] In a further preferred embodiment of the present invention, a synchronous sprocket 26 is fixedly installed on any power shaft of the drying conveyor belt 6 and the discharge conveyor belt 7 and the input shaft of the fan blade assembly 15, and the three synchronous sprockets 26 are sleeved with the same chain 27. A drive motor 28 is fixedly installed on one side of the discharge box 2, and the output shaft of the drive motor 28 is fixedly connected to the corresponding power shaft of the discharge conveyor belt 7.

[0066] In this embodiment, the drive motor 28 fixedly installed on one side of the discharge box 2 is started. The output shaft of the drive motor 28 is fixedly connected to the power shaft of the discharge conveyor belt 7, so when the drive motor 28 is started, it will drive the discharge conveyor belt 7 to start running.

[0067] Due to the linkage between the synchronous sprocket 26 and the chain 1 27, when the discharge conveyor belt 7 starts to operate, it will drive the power shaft of the drying conveyor belt 6 and the input shaft of the fan assembly 15 to rotate synchronously through the chain 1 27. In this way, the drying conveyor belt 6, the discharge conveyor belt 7 and the fan assembly 15 can operate at the same speed to achieve an efficient drying and discharge process.

[0068] In a further preferred embodiment of the present invention, a guide ramp is fixedly installed at the entrance of the discharge port 4 , and the top of the guide ramp extends to below the discharge end of the discharge conveyor belt 7 .

[0069] In this embodiment, the top of the guide ramp extends to below the discharge end of the discharge conveyor belt 7, forming a natural connection with the discharge conveyor belt 7. When the discharge conveyor belt 7 transports the dried material to the discharge end, the material will slide onto the guide ramp and then slowly slide into the discharge port 4 along the inclined surface of the guide ramp, ensuring that the material can enter the discharge port 4 smoothly and orderly.

[0070] In a further preferred embodiment of the present invention, the top of the chili paste storage barrel 5 is provided with a filling hopper, the top of the filling hopper is provided with a top cover, and the bottom of the chili paste storage barrel 5 is a funnel-shaped structure.

[0071] In this embodiment, the chili paste storage barrel 5 is a key component for storing chili paste, and a filling hopper is designed on the top to facilitate users to fill the chili paste into the barrel. The top of the filling hopper is also equipped with a top cover. When filling is not needed, the top cover can be closed to prevent dust, impurities, etc. from entering the storage barrel, thereby ensuring the cleanliness of the chili paste. In addition, the bottom of the chili paste storage barrel 5 adopts a funnel-shaped structure design, which makes the chili paste more smooth when discharged, and is not easy to block the discharge port, and is also convenient for subsequent cleaning and maintenance.

[0072] In actual operation, the user only needs to open the top cover of the filling hopper, pour the chili paste into the storage barrel through the filling hopper, and then close the top cover. When the chili paste needs to be used, just open the discharge port at the bottom of the storage barrel, and the chili paste will flow out smoothly along the funnel-shaped structure.

[0073] In a further preferred embodiment of the present invention, the rotational speed ratio of the drying conveyor belt 6 and the discharge conveyor belt 7 is 1:1, and the rotational speed ratio of the drying conveyor belt 6 and the fan blade assembly 15 is 1:6-10.

[0074] In this embodiment, the speed ratio of the drying conveyor belt 6 and the discharge conveyor belt 7 is set to 1:1, which means that they run at the same speed, ensuring the continuity and synchronization of the material during the drying and discharge process. At the same time, the speed ratio of the drying conveyor belt 6 and the fan blade assembly 15 is set to 1:6-10. This ratio range is intended to optimize the drying efficiency and ensure that the material can be fully affected by the airflow generated by the fan blade assembly during the transmission process, thereby achieving a more efficient drying effect.

[0075] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0076] In another embodiment of the present invention, the drying box 1 and the chili slurry storage barrel 5 are connected by a discharging slurry spreading mechanism for evenly spreading slurry on the drying conveyor belt 6. The discharging slurry spreading mechanism includes a chili slurry distributing box 29, a slurry discharging pipe 30, an electric telescopic rod 32, a suspension plate 33, two assembly side plates 34, a rectangular guide plate 35, a connecting tube plate 36, a plurality of slurry distributing pipes 37, a plurality of telescopic hoses 38, a reciprocating screw 39 and a slurry spreading reciprocating drive mechanism. The chili slurry distributing box 29 is fixedly installed on the drying On the top inner wall of the box 1, the chili slurry distribution box 29 is located below the chili slurry storage barrel 5 and above the feeding side of the drying conveyor belt 6. The width of the chili slurry distribution box 29 is equal to the drying conveyor belt 6. The slurry discharge pipe 30 is connected to the bottom of the chili slurry storage barrel 5 and the top of the chili slurry distribution box 29. A valve is provided on the slurry discharge pipe 30. The electric telescopic rod 32 is fixedly installed on the top of the drying box 1. The output rod of the electric telescopic rod 32 extends into the drying box 1. The suspension The plate 33 is fixedly mounted on the output rod of the electric telescopic rod 32, the suspension plate 33 is located above the drying conveyor belt 6, the two assembly side plates 34 are fixedly mounted on the bottom of the suspension plate 33, the rectangular guide plate 35 is fixedly mounted between the two assembly side plates 34, the connecting tube plate 36 is slidably sleeved on the rectangular guide plate 35, and the plurality of slurry pipes 37 are fixedly mounted on the connecting tube plate 36 for evenly distributing the chili slurry on the drying conveyor belt 6, the plurality of telescopic hoses 38 are respectively fixedly mounted on the top ends of the plurality of slurry pipes 37, and the plurality of telescopic hoses 38 are fixedly connected to the bottom of the chili slurry equalizing box 29, the reciprocating screw 39 is rotatably mounted on the two assembly side plates 34, the reciprocating screw 39 threadably penetrates the connecting tube plate 36, and the slurry spreading reciprocating drive mechanism is arranged on the two assembly side plates 34, for driving the reciprocating screw 39 to rotate reciprocatingly, so that the connecting tube plate 36 drives the plurality of slurry pipes 37 to slide reciprocatingly.

[0077] In this embodiment, the discharging and spreading mechanism can evenly spread the chili paste from the chili paste storage barrel 5 to the drying conveyor belt 6. The specific method of use is as follows:

[0078] First, the chili paste is stored in the chili paste storage barrel 5. When the chili paste needs to be spread, the valve on the discharge pipe 30 is opened, and the chili paste flows into the chili paste distribution box 29 through the discharge pipe 30. The chili paste distribution box 29 is located above the feed side of the drying conveyor belt 6, and its width is equal to that of the drying conveyor belt 6 to ensure that the chili paste can be evenly distributed.

[0079] Next, the electric telescopic rod 32 is started, and its output rod extends downward, driving the suspension plate 33 and the assembly side plate 34, rectangular guide plate 35, tube plate 36 and slurry pipe 37 and other components below it to descend, so that the slurry pipe 37 is close to the drying conveyor belt 6. At the same time, the slurry spreading reciprocating drive mechanism is started to drive the reciprocating screw 1 39 to reciprocate on the two assembly side plates 34. Since the reciprocating screw 1 39 thread penetrates the tube plate 36, the tube plate 36 will reciprocate and slide with the rotation of the reciprocating screw 1 39, driving multiple slurry pipes 37 to reciprocate above the drying conveyor belt 6.

[0080] During the reciprocating movement of the slurry distributing pipe 37, the chili slurry flows from the chili slurry distributing box 29 into the slurry distributing pipe 37 through the telescopic hose 38 and is evenly distributed on the drying conveyor belt 6. The telescopic movement of the electric telescopic rod 32 and the reciprocating rotation of the slurry distributing reciprocating driving mechanism can work together to adjust the thickness and uniformity of the slurry distributing.

[0081] By introducing the slurry discharging and spreading mechanism, especially the reciprocating movement of the slurry distributing pipe 37 and the telescopic function of the electric telescopic rod 32, it can be ensured that the chili slurry is evenly distributed on the drying conveyor belt 6, thereby improving the drying efficiency and product quality. The design of the slurry discharging and spreading mechanism automates the slurry spreading process, reduces the complexity and labor intensity of manual operation, and improves work efficiency.

[0082] In another embodiment of the present invention, a slurry guard plate 31 is fixedly installed on the top inner wall of the drying box 1 , and the bottom of the slurry guard plate 31 is in contact with the feeding side of the drying conveyor belt 6 .

[0083] In this embodiment, when the chili slurry is evenly spread on the drying conveyor belt 6 through the slurry discharging and spreading mechanism, the slurry baffle 31 can ensure that the chili slurry can move smoothly along the predetermined path of the drying conveyor belt 6 to avoid overflowing in other directions.

[0084] In another embodiment of the present invention, the slurry-laying reciprocating drive mechanism comprises a power conversion shaft 40, a belt pulley 41, a pulley 42, a synchronous belt 43, a circular gear 44, an intermediate connecting plate 45, a T-shaped guide plate 46, a reciprocating rack 47, an intermediate connecting plate 2 48, a driving motor 49, an eccentric slat 50 and a hinge plate 51, wherein the power conversion shaft 40 is rotatably mounted on the two assembly side plates 34, the belt pulley 41 is fixedly sleeved on the power conversion shaft 40, the pulley 42 is fixedly sleeved on the reciprocating screw 39, the synchronous belt 43 is sleeved on the belt pulley 41 and the pulley 42, and the circular gear 44 is fixedly sleeved on the two assembly side plates 34. The power conversion shaft 140 is fixedly mounted on the intermediate connecting plate 145 between the two assembly side plates 34, the T-shaped guide plate 146 is fixedly mounted on the intermediate connecting plate 145, the reciprocating rack 147 is slidably mounted on the T-shaped guide plate 146, the reciprocating rack 147 is meshed with the circular gear 144, the intermediate connecting plate 248 is fixedly mounted between the two assembly side plates 34, the driving motor 49 is fixedly mounted on the intermediate connecting plate 248, the eccentric strip plate 50 is eccentrically fixedly mounted on the output shaft of the driving motor 49, and the hinged plate 51 is hingedly mounted on the eccentric strip plate 50 and the reciprocating rack 147.

[0085] In this embodiment, when in use, the driving motor 49 is first started, and its output shaft drives the eccentric strip 50 to rotate. Since the eccentric strip 50 is hingedly connected to the hinge plate 51, the hinge plate 51 will swing left and right with the rotation of the eccentric strip 50. This swinging motion is transmitted to the reciprocating rack 1 47 through the hinge plate 51, so that the reciprocating rack 1 47 slides back and forth on the T-shaped guide plate 1 46.

[0086] At the same time, the reciprocating rack 47 drives the meshing circular gear 44 to rotate, thereby driving the power conversion shaft 40 to rotate as well. The power conversion shaft 40 uses a belt pulley 41, a pulley 42 and a synchronous belt 43 to drive the reciprocating screw 39 to reciprocate. This reciprocating linear motion is then transmitted to the slurry distribution pipe 37 through the connecting tube plate 36, causing the slurry distribution pipe 37 to move back and forth to achieve uniform slurry spreading.

[0087] In another embodiment of the present invention, a fixed strip 52 is fixedly installed at the bottom of the middle connecting plate 48 , and a slurry pressing plate 53 is fixedly installed at the bottom of the fixed strip 52 . The slurry pressing plate 53 is located on the discharge side of the slurry distribution pipe 37 .

[0088] In this embodiment, a fixed strip 52 is fixedly installed at the bottom of the middle connecting plate 2 48, and a slurry pressing plate 53 is fixedly installed at the bottom of the fixed strip 52. The slurry pressing plate 53 is cleverly designed at the discharge side of the slurry distributing pipe 37, that is, the position where the chili slurry is discharged from the slurry distributing pipe 37 and falls on the drying conveyor belt 6.

[0089] When the driving motor 49 is started and drives the pulp distributing pipe 37 to move back and forth to spread the pulp, the squeezing plate 53 also moves accordingly. Since the squeezing plate 53 is located on the discharge side of the pulp distributing pipe 37, it can timely slightly compact the chili pulp just discharged, ensuring that the chili pulp forms a uniform and compact thin layer on the drying conveyor belt 6. This design not only helps to improve the drying efficiency, but also prevents the chili pulp from cracking or deforming due to looseness during the drying process.

[0090] In another embodiment of the present invention, the chili slurry distribution box 29 and the drying box 1 are provided with a slurry entering and spreading mechanism, and the slurry entering and spreading mechanism includes a reciprocating screw rod 2 54, a material scraper 55, a power conversion shaft 2 56, a large chain plate 57, a small sprocket 58, a chain 2 59, a T-shaped guide plate 2 60, a reciprocating rack 2 61, a recoil spring 62, a guide wheel 63, a push cam 64 and a circular gear 2 65. The reciprocating screw rod 2 54 is rotatably installed in the chili slurry distribution box 29, the material scraper 55 is slidably installed in the chili slurry distribution box 29 and is threadedly sleeved on the reciprocating screw rod 2 54, the power conversion shaft 2 56 is rotatably installed on one side of the drying box 1, the large chain plate 57 is fixedly sleeved on the power conversion shaft 2 56, and the small sprocket 58 is fixedly sleeved on the small sprocket 58. The fixed sleeve is arranged at one end of the reciprocating screw rod 54, the chain 59 is sleeved on the large chain plate 57 and the small sprocket 58, the T-shaped guide plate 60 is fixedly installed on the side of the drying box 1, the reciprocating rack 61 is slidably sleeved on the T-shaped guide plate 60, the recoil spring 62 is installed in the chamber of the reciprocating rack 61 and conflicts with the T-shaped guide plate 60, the guide wheel 63 is installed at one end of the reciprocating rack 61 by a wheel frame, the push cam 64 is arranged on one side of the guide wheel 63 and contacts therewith, the push cam 64 is fixedly connected to the corresponding input shaft of the drying conveyor belt 6, the circular gear 65 is fixedly sleeved on the power conversion shaft 56, and the circular gear 65 is meshed with the reciprocating rack 61.

[0091] In this embodiment, when in use, due to the rotation of the drying conveyor belt 6, its input shaft will drive the push cam 64 to rotate, and the push cam 64 will push the guide wheel 63, so that the reciprocating rack 2 61 slides along the T-shaped guide plate 2 60 and compresses the return spring 62. At this time, the reciprocating linear motion of the reciprocating rack 2 61 drives the meshing circular gear 2 65 to rotate, so that the power conversion shaft 2 56 drives the large chain plate 57 to rotate synchronously. Since the large chain plate 57 is connected to the small sprocket 58 through the chain 2 59, the small sprocket 58 will also rotate, thereby driving the reciprocating screw 2 54 to rotate in the chili paste distribution box 29. The material scraper 55 is threadedly sleeved on the reciprocating screw 2 54, so it will reciprocate in the chili paste distribution box 29 with the rotation of the reciprocating screw 2 54, so that the chili paste is evenly scraped in the chili paste distribution box 29.

[0092] The material scraper 55 is driven by the reciprocating screw 54 to reciprocate in the chili paste distribution box 29, thereby ensuring uniform scraping of the chili paste and avoiding accumulation and clogging of the chili paste.

[0093] In summary, compared with the relevant technology, the device significantly improves the drying efficiency of the chili paste and shortens the production cycle through the precise heating of the infrared drying radiator 10. The application of the air spiciness removal mechanism effectively reduces the diffusion of spicy air during the drying process, reduces the irritation and harm to production personnel, and improves the working environment.

[0094] A process for processing and drying agricultural products, using the agricultural product processing and drying device as claimed in claims 1 to 9 for processing, comprising the following steps:

[0095] Step 1: Dry the chili paste after sterilization and residue removal, high-pressure spray cleaning, color sorting machine sorting, seed and meat separation, crushing and granulation to eliminate the waxy film. Before drying, first pour the chili paste into the chili paste storage barrel 5;

[0096] Step 2: During drying, the infrared drying radiator 10 is started, and the infrared radiator 11 is started at the same time, so that the drying conveyor belt 6, the discharge conveyor belt 7 and the fan assembly 15 are synchronously driven under the action of the synchronous sprocket 26 and the chain 27, and the chili paste is discharged into the drying conveyor belt 6 of the drying box 1 through the chili paste storage barrel 5. The drying conveyor belt 6 transmits the chili paste through the infrared drying radiator 10 and the infrared radiator 11 for drying. During the transmission process, the rake plate 21 adopts the rake mouth 22 cooperates to turn the pepper slurry. At this time, air enters through the air inlet pipe 12. Since the heated hot air is lighter, it will carry the pungent spicy taste of the pepper on the top. After passing through the interior of the drying box 1, the air is discharged into the drainage shell 14 through the air outlet pipe 13, and then discharged into the aeration main pipe 16 after being rotated and drained by the fan blade assembly 15, and finally discharged into the aeration box 17 for removing the spicy air through the aeration branch pipe 18. The spicy air is mixed with the solution in the aeration box 17 for removing the spicy air, and the air after the spicy air is removed is discharged from the aeration box 17;

[0097] Step three: When the chili paste has completely passed through the drying conveyor belt 6 and reaches its tail section, it is dried into chili particles with a moisture content of 5 to 10%. At this time, the material pushes open the soft stopper 24 and falls onto the discharge conveyor belt 7 below, and is finally discharged from the discharge port 4. Since the chili particles contain heat and continue to evaporate to produce spicy taste, when the chili particles are transmitted on the discharge conveyor belt 7, the air in the discharge box 2 is introduced into the air outlet pipe 13 by the conduction branch pipe 20 and the conduction main pipe 19, and then merged to remove the spicy taste.
