Description

Technical Field

[0001] The invention relates to the technical field of draining and air-drying equipment, and more specifically to a draining and air-drying equipment for processing fruit agricultural products and dried fruit finished products. Background Art

[0002] The processing of dried fruit products is to remove moisture from fruit products and reduce the moisture content inside the fruit, thereby extending the shelf life of the fruit. At the same time, dried fruit products are easier to store and transport than fresh fruits, or to increase the flavor and taste of the fruit. After the fruit is dried, the taste and flavor will change, usually becoming richer and sweeter. At the same time, dried fruit products are more expensive than fresh fruits. Processed dried fruit products can often add added value to agricultural products and improve the economic benefits of agricultural products.

[0003] At present, when fruit agricultural products are dried, the main method of draining and air-drying is to use a vibrating screen. Fresh fruits are placed on the vibrating screen, and then the vibrating screen is started. Through the left and right shaking of the vibrating screen, the moisture on the surface of the fresh fruits passes through the shaking of the vibrating screen, so that the moisture is separated from the surface of the fresh fruits through the water filtering holes on the surface of the vibrating screen. The surface of the fresh fruits is air-dried by the air-drying fan above the vibrating screen. However, since the left and right shaking of the vibrating screen cannot turn the fresh fruits over, only one side of the fresh fruits is air-dried by the air-drying fan, which results in that the fresh fruits cannot be air-dried evenly, resulting in a decrease in the taste of the finished dried fruits. For this reason, the prior art uses multiple vibrating screens and conveyor belts arranged in a stepped manner. A drying fan is arranged above each vibrating screen. The vibrating screen is shaken left and right in cooperation with the drying fan to dry the fresh fruits on the conveyor belt, thereby ensuring that moisture is removed from the fresh fruits. The stepped conveyor belt can turn the fruits over when conveying the fruits, so that the side of the fresh fruits that is in contact with the conveyor belt is turned upward, thereby making the fresh fruits evenly dried and avoiding uneven drying that affects the taste of the dried fruits. However, the stepped conveyor belt cannot ensure that the fresh fruits are completely turned over during the conveying process, resulting in over-drying or under-drying of the fresh fruits, making the dried fruits unevenly dried, reducing the shelf life of the dried fruits and affecting the quality of the products.

[0004] In view of the above situation, the present invention designs a drainage and air-drying device for processing fruit agricultural products and dried fruit products, which solves the above technical problems. Summary of the invention

[0019] Beneficial effects of the present invention:

[0020] 1. The present invention provides a drainage and air-drying device for processing fruit agricultural products and dried fruit products. The device drives a driving mechanism to move synchronously through a power device, so that a drying plate rotates on a support seat. During the drying process, the drying plate cooperates with the rotation of an inner cylinder to turn the fresh fruit over in the inner cylinder, thereby ensuring that the surface of the fresh fruit is dried evenly, avoiding the phenomenon of over-drying or under-drying of the fresh fruit during the drying process, thereby affecting the taste of the dried fruit after drying, and further reducing the quality of the dried fruit product.

[0021] 2. The present invention provides a drainage and air-drying device for processing finished dried fruit products of fruit agricultural products. The device cooperates with a circulation component through an air-drying component. Since hot air is passed through the air-drying plate, the hot air dries the fresh fruit through the air-drying holes during the air-drying process, thereby ensuring that the surface of the fresh fruit can be evenly dried. After the fresh fruit has been dried with hot air for a period of time, the air bag in the circulation component continues to expand with the rotation of the inner cylinder, pushing the rotating shaft to move, and the ventilation holes coincide with the openings of the circulation blades on the circulation cavity, thereby discharging the gas in the air bag through the circulation holes, and performing cold air drying on the fresh fruit. Furthermore, during the air-drying process, the fresh fruit is dried respectively by the hot air on the air-drying plate and the cold air on the circulation blades, thereby accelerating the drying of the fresh fruit, thereby improving the production efficiency of the dried fruit.

[0022] 3. The present invention provides a drainage and air-drying device for processing finished dried fruit products of fruit agricultural products. The device rotates the inner cylinder so that the spiral scraper on the outer surface of the inner cylinder fits against the inner side of the outer cylinder for scraping, and collects the moisture on the surface of the fresh fruit inside the outer cylinder when the inner cylinder rotates, to prevent the moisture from condensing into water droplets and falling on the surface of the dried fruit to cause moisture. At the same time, the spiral blades arranged on the inner side of the inner cylinder can prevent the fresh fruit from piling up inside, so that the fresh fruit is evenly dispersed, to avoid uneven air-drying.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0035] refer to Figure 1-3As shown, a drainage and air-drying device for processing finished fruit and agricultural products is used for air-drying and forming agricultural products and dried fruits, comprising a device body 1, an outer cylinder 11 is arranged on the device body 1, and a conical water collecting tank 111 is arranged at the bottom of the outer cylinder 11, the outer cylinder 11 is divided into a movable end 112 and a fixed end 113, a power device 2 is arranged on one side of the fixed end 113, an inner cylinder 12 is coaxially installed inside the outer cylinder 11, and an air-drying component 3 is arranged inside the outer cylinder 11, the air-drying component 3 comprises a driving mechanism 31, a supporting seat 32, and an air-drying plate 33, the driving mechanism 31 is installed through the inner cylinder 12, and the driving mechanism 31 is connected to the power device 2, the driving mechanism The structure 31 drives the inner cylinder 12 to move synchronously through the power device 2. A drying plate 33 is installed on one side of the driving mechanism 31, and there are multiple drying plates 33. One side of the drying plate 33 is connected to the driving mechanism 31 through a support seat 32, and the other side of the drying plate 33 is rotatably connected to the inner cylinder 12 through the support seat 32; a plurality of drying holes 331 are arranged in an array on the drying plate 33, and the inner diameter of the drying hole 331 is smaller than the outer diameter. The power device 2 drives the driving mechanism 31 to move synchronously, and the driving mechanism 31 drives the drying plate 33 and the inner cylinder 12 to move synchronously. The inner cylinder 12 and the drying plate 33 move synchronously to change the position of the dried fruit inside the inner cylinder 12.

[0036] During the working process, the staff first removes the movable end 112, places the fresh fruit inside the inner cylinder 12, and then starts the power device 2, which drives the driving mechanism 31 to move synchronously. Since the support seat 32 on one side is connected to the driving mechanism 31, the support seat 32 on the other side is rotatably connected to one side of the inner cylinder 12, and the air-drying plate 33 is installed between the two support seats 32, the movement of the driving mechanism 31 drives the inner cylinder 12 and the air-drying plate 33 to move synchronously. The inner cylinder 12 rotates, and the fresh fruit inside it rotates with the rotation of the inner cylinder 12. When the fresh fruit rotates to the top with the rotation of the inner cylinder 12, the fresh fruit falls on the air-drying plate 33 due to its own gravity, and passes through the hot air duct before the draining and air-drying work begins. (Not shown in the figure) Hot air is continuously input to the air-drying plate 33. When fresh fruits fall on the air-drying plate 33, the hot air passing through the air-drying holes 331 can dry the surface of the fresh fruits. When the air-drying plate 33 rotates, the fresh fruits can be turned over to ensure that the surface of the fresh fruits is heated evenly. At the same time, the rotation of the inner cylinder 12 can throw out the moisture on the surface of the fresh fruits using the principle of centrifugal force, thereby removing excess moisture on the surface of the fresh fruits and collecting it through a conical water collection tank 111 set at the bottom of the outer cylinder 11. The water inside the water collection tank can be reused later. The air-drying time of different fruits is different. When the fresh fruits are dried, the operator can remove the movable end 112 to take out the dried fruits inside, thereby completing the air-drying of fruit and agricultural products.

[0037] A plurality of water filtering holes 122 are arranged in an array on the circumferential surface of the inner cylinder 12, and the shape of the water filtering holes 122 is truncated cone-shaped. When the inner cylinder 12 rotates, the centrifugal force principle is utilized to make the excess water on the surface of the fresh fruit be thrown out of the inner cylinder 12 through the water filtering holes 122 and adhere to the inner surface of the outer cylinder 11. At the same time, the truncated cone-shaped water filtering holes 122 can prevent the water on the inner side of the outer cylinder 11 from condensing into water droplets and dripping into the inner cylinder 12, thereby causing the dried fruit to become damp after being air-dried, thereby affecting the taste of the dried fruit. Such an arrangement can reduce the dampness phenomenon of the dried fruit after being air-dried.

[0038] The outer circumferential surface of the inner cylinder 12 is provided with a spiral scraper 121, and the spiral scraper 121 is in contact with the inner circumferential surface of the outer cylinder 11. The inner circumferential surface of the inner cylinder 12 is provided with a spiral blade 123, and the spiral blade 123 forms a spiral channel with the inner cylinder 12. When the inner cylinder 12 rotates, the spiral scraper 121 fixedly arranged on the outer side rotates with the rotation of the inner cylinder 12, and the spiral scraper 121 rotates closely against the inner surface of the outer cylinder 11. At this time, the moisture on the surface of the fresh fruit adhering to the inner side of the outer cylinder 11 is removed by the spiral scraper 123. The rotation of the spiral scraper 121 gathers the water together. When the spiral scraper 121 passes through the conical water collecting tank 111, the gathered water falls into the conical water collecting tank 111 due to its own gravity. After the dried fruit processing is completed, the water in the conical water collecting tank 111 can be reused. By arranging the spiral blades 123 on the inner side of the inner cylinder 12, when the inner cylinder 12 rotates, the spiral channel formed by the spiral blades 123 and the inner cylinder 12 is used. During the rotation process, the accumulated fresh fruits are evenly dispersed to avoid the phenomenon of uneven drying caused by accumulation.

[0039] The power device 2 includes a motor 21, a driving wheel 22, a tensioning belt 23, a driven wheel 24, a transmission gear 25 and a rotating gear 26. The motor 21 is arranged below the equipment body 1, and the output end of the motor 21 is provided with a driving wheel 22, the driving wheel 22 is connected to the driven wheel 24 through the tensioning belt 23, the driven wheel 24 is arranged below the central axis of the outer cylinder 11, a transmission gear 25 is arranged on one side of the driven wheel 24, the transmission gear 25 is coaxially installed with the driven wheel 24, a rotating gear 26 is arranged above the transmission gear 25, and the rotating gear 26 is meshed with the transmission gear 25, and the rotating gear 26 is fixedly arranged on one side of the inner cylinder 12.

[0040] During operation, when the operator starts the motor 21, the motor 21 rotates to drive the driving wheel 22 set at its output end to move at the same frequency. Since the driving wheel 22 and the driven wheel 24 are connected by the tensioning belt 23, the rotation of the driving wheel 22 drives the driven wheel 24 to rotate. The driven wheel 24 is coaxially installed with the transmission gear 25, so that the driven wheel 24 and the transmission gear 25 move synchronously. During the rotation of the transmission gear 25, it meshes with the rotating gear 26, thereby driving the rotating gear 26 to rotate. Since the rotating gear 26 is installed on one side of the inner cylinder 12, the inner cylinder 12 rotates along with the rotation of the rotating gear 26.

[0041] The driving mechanism 31 includes a rotating shaft 311, a rotating frame 312, a fixed gear 313 and a driven gear 314. The rotating shaft 311 passes through the inner cylinder 12 and is fixedly arranged on one side of the outer cylinder 11. The inner cylinder 12 is rotatably mounted on the rotating shaft 311. The rotating frame 312 is rotatably arranged on the rotating shaft 311, and the fixed gear 313 is fixedly arranged on the end of the rotating shaft 311 away from the inner cylinder 12. The rotating frame 312 is cross-shaped, and a driven gear 314 is arranged at each end of the cross. The driven gear 314 is meshed with the fixed gear 313, and the driven gear 314 is connected to the support seat 32.

[0042] When the inner cylinder 12 rotates with the rotation of the rotating gear 26, and the rotating shaft 311 is rotatably installed with the inner cylinder 12, the smooth rotation of the inner cylinder 12 can be ensured by the support of the rotating shaft 311. A rotating frame 312 is provided on one side of the inner cylinder 12, and the rotating frame 312 is fixedly connected to the inner cylinder 12, and the rotating frame 312 is rotatably installed with the rotating shaft 311. The rotation of the inner cylinder 12 drives the rotating frame 312 to rotate accordingly. Since the fixed gear 313 is fixedly provided at one end of the rotating shaft 311, a driven gear 314 is rotatably provided on the rotating frame 312, and the driven gear 314 is fixedly installed with the support seat 32. The rotation of the inner cylinder 12 drives the rotating frame 312 to rotate accordingly. At this time, the driven gear 314 is meshed with the fixed gear 313, thereby realizing the self-rotation of the driven gear 314, and at the same time, the support seat 32 and the driven gear 314 move synchronously.

[0043] The circulation assembly 4 includes a limit frame 41, a limit block 42, a turbine blade 43, an airbag 44, a rotating shaft 45, a circulation blade 46 and a ventilation mechanism 47. The limit frame 41 is arranged on one side of the movable end 112. The limit block 42 is arranged at the central axis of the limit frame 41. The limit block 42 is stepped. A guide cavity 421 is opened inside the limit block 42. The inner side of the guide cavity 421 is provided with a turbine blade 43. The turbine blade 43 is coaxially installed with the limit frame 41. The limit block 42 is An airbag 44 is provided on one side, and the outlet of the guide cavity 421 is connected to the air inlet of the airbag 44. A rotating shaft 45 is connected to the other side of the airbag 44. A circulation cavity 451 is provided inside the rotating shaft 45, and a plurality of circulation blades 46 are arranged in an array on the outer circumferential surface of the rotating shaft 45. The circulation blades 46 are hollow and communicate with the circulation cavity 451. A plurality of circulation holes 461 are provided on the circulation blades 46. The rotating shaft 45 is connected to the rotating shaft 311 through a ventilation mechanism 47.

[0044] During operation, when the inner cylinder 12 rotates to drain and air-dry the fresh fruit, the rotation of the inner cylinder 12 drives the coaxially arranged limit frame 41 to rotate, and the rotation of the limit frame 41 drives the turbine blades 43 to rotate. The turbine blades 43 rotate through the air suction holes 1121 provided on the outer shell, and the cold air from the outside flows into the air bag 44 from the guide cavity 421. The expansion of the air bag 44 pushes the ventilation mechanism 47. The ventilation mechanism 47 allows the cold air inside the air bag 44 to flow from the flow cavity inside the rotating shaft 45 to the circulating blades 46. At this time, the hot air in the air-drying plate 33 forms convection with the cold air from the outside to accelerate the drying speed of the fresh fruit and improve the drying efficiency of the equipment. Since the rotating shaft 45 does not rotate with the rotation of the inner cylinder 12, the circulating blades 46 can avoid the phenomenon of uneven drying caused by excessive accumulation of fresh fruit, thereby ensuring the drying quality of the dried fruit product.

[0045] A guide ring 124 is provided on the inner side of the inner tube 12. The width of the guide ring 124 is greater than the width of the airbag 44 in the initial state, and the airbag 44 is installed close to the guide ring 124. The guide ring 124 limits the expansion direction of the airbag 44, so that the airbag 44 expands along the direction of the guide ring 124, while being able to give the airbag 44 sufficient expansion distance.

[0046] The movable end 112 is rotatably connected to the limit frame 41, and the limit frame 41 is fixedly connected to the limit block 42. The movable end 112 is connected to the fixed end 113 by threads, and the limit block 42 is detachably connected to the guide ring 124. The diameter of the limit block 42 is consistent with the diameter of the airbag 44. This arrangement can ensure the overall sealing and avoid leakage of internal hot air. By ensuring that the movable end 112 is tightly connected to the fixed end 113, the smooth operation of the equipment is guaranteed. By setting the diameter of the limit block 42 consistent with the diameter of the airbag 44, the deviation of the airbag 44 during expansion is avoided, and the stability of the equipment during movement is avoided.

[0047] The ventilation mechanism 47 includes an offset plate 471, a ventilation hole 472 and a spring 473. The rotating shaft 45 is fixedly connected to the rotating shaft through the spring 473. The offset plate 471 is arranged in the circulation cavity 451, and the offset plate 471 is slidably connected to the rotating shaft. The offset plate 471 is provided with a ventilation hole 472. The shape of the ventilation hole 472 is consistent with the shape of the circulating blade 46 communicating with the circulation cavity 451.

[0048] During operation, the airbag 44 expands and pushes the rotating shaft 45 to move. When the rotating shaft 45 moves, the spring 473 is squeezed. At this time, the ventilation hole 472 on the offset plate 471 and the hole communicating with the circulation blade 46 and the flow cavity 451 gradually overlap. The cold air in the airbag 44 flows out from the circulation hole 461 on the circulation blade 46 to dry the surface of the fresh fruit. When the inner cylinder 12 no longer rotates and the airbag 44 cannot expand, the rotating shaft 45 returns to its original position due to the elastic potential energy of the spring 473.

[0049] The circulation blades 46 are perpendicular to the central axis of the rotating shaft 45, and the angle formed is less than 45°, so as to prevent the circulation blades 46 from damaging the softer fresh fruits when the inner cylinder 12 rotates, thereby avoiding affecting the taste of the dried fruits. The circulation holes 461 on the circulation blades 46 are in the shape of an inverted cone. Such an arrangement can expand the circulation range of the cold air, thereby increasing the contact area between the cold air and the fresh fruits.
