Description

Technical Field

[0001] This utility model relates to the field of dehydrated carrot granule production technology, and in particular to a screening device for dehydrated carrot granule production. Background Technology

[0002] Dehydrated carrot granules are a type of carrot product made by washing, peeling, dicing, and drying (dehydrating) fresh carrots. The key is to remove more than 90% of the water from fresh carrots (usually reducing the moisture content to below 10%), while retaining the main nutrients and flavor of carrots, significantly extending the shelf life and reducing the volume. During the production process, a screening device is needed to remove unqualified granules to ensure product consistency and avoid "mixing of sizes" that may affect the consumer experience.

[0003] However, current traditional screening devices only provide screening through vibration screening, lacking lateral force, resulting in poor screening effect. Furthermore, carrot granules may slightly stick together due to moisture, easily forming small clumps that clog the screen holes. Utility Model Content

[0004] The purpose of this invention is to provide a screening device for the production of dehydrated carrot granules, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screening device for producing dehydrated carrot granules, comprising a housing and a working component. The working component is installed inside the housing. The working component includes a fixed isolation plate fixedly connected to the upper part of the inner wall of the housing. A first electric telescopic rod is installed on the lower top surface of the fixed isolation plate. A blower is fixedly connected to the telescopic end of the first electric telescopic rod. A fan is connected to one side of the blower via a hose. A heating box is connected to the other side of the fan via a pipe. An electric heating rod is installed inside the heating box. A dust filter is installed on the outside of the heating box.

[0006] Preferably, a second electric telescopic rod is installed in the middle of the inner wall of the box, and a movable isolation plate is fixedly connected to the telescopic end of the second electric telescopic rod. The surface of the movable isolation plate is embedded with an isolation filter screen.

[0007] Preferably, sleeve rods are fixedly connected to the top of both sides of the box body, springs are installed at the top of the inner wall of the sleeve rods, extension rods are slidably connected to the inner side of the sleeve rods through slots, the top of the extension rods abuts against the springs, a connecting frame is fixedly connected to the bottom of the extension rods, a screen is fixedly connected to the bottom inner side of the connecting frame, and a first arc-shaped block is fixedly connected to the bottom outer side of the connecting frame.

[0008] Preferably, brackets are fixedly connected to the lower sides of the box body, a drive motor is installed at the top of the bracket, the output end of the drive motor is connected to a turntable via a shaft key, a transmission rod is rotatably connected to one side of the turntable via a shaft, and a C-shaped rod is rotatably connected to the other end of the transmission rod via a shaft.

[0009] Preferably, a limiting frame is slidably connected to the outer side of the C-shaped rod via a slot, the bottom of the limiting frame is fixedly connected to the housing, an auxiliary frame is slidably connected to one end of the C-shaped rod via a slot, the bottom of the auxiliary frame is fixedly connected to the housing, and a second arc-shaped block is fixedly connected to the top of the C-shaped rod. Multiple sets of the second arc-shaped blocks are provided, and the upper surface of the second arc-shaped block abuts against the first arc-shaped block.

[0010] Preferably, a feed inlet is fixedly connected to the upper surface of the box, a first guide plate is fixedly connected to the lower inner wall of the box, and a second guide plate is fixedly connected to the bottom of the first guide plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The working components provide a transverse hot air structure, which improves particle flowability and accelerates screening through airflow. The hot air can quickly remove trace amounts of moisture from the particle surface, breaking down the stickiness of the particles and dispersing clumps into individual particles, ensuring that the screen holes are not blocked. The fan provides power to drive outside air into the heating chamber. The dust filter screen isolates dust and impurities from entering the device with the airflow. After the electric heating rod is powered, it generates heat radiation to heat the air. The hot air is introduced by the fan through the hose and sprayed out from the nozzle. The extension and retraction of the first electric telescopic rod drives the nozzle to move vertically, improving the flexibility of the hot air. The fixed isolation plate and the movable isolation plate form an isolation structure to prevent material from falling out. The isolation filter screen blocks the material while ensuring the passage of hot air.

[0012] 2. The drive motor provides power to rotate the turntable, which causes the transmission rod to drive the C-shaped rod to move horizontally back and forth in the slot of the limit frame. The auxiliary frame provides auxiliary support, which causes the second arc-shaped block to follow the back and forth movement. During the process of abutting against the first arc-shaped block, the connecting frame moves vertically in the slot of the box, which drives the screen to throw the material up to enhance the screening effect. The sleeve rod, spring and extension rod form an elastic structure to provide a certain top elasticity effect to prevent the connecting frame from being thrown too high and causing damage.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 As shown, a screening device for producing dehydrated carrot granules includes a housing 1 and a working assembly 2. The working assembly 2 is installed inside the housing 1. The working assembly 2 includes a fixed isolation plate 201 fixedly connected to the upper part of the inner wall of the housing 1. A first electric telescopic rod 202 is installed on the lower top surface of the fixed isolation plate 201. A blower head 203 is fixedly connected to the telescopic end of the first electric telescopic rod 202. A blower 204 is connected to one side of the blower head 203 through a hose. A heating box 205 is connected to the other side of the blower 204 through a pipe. An electric heating rod 206 is installed inside the heating box 205. A protective shield is installed on the outside of the heating box 205. The dust filter 207 provides a transverse hot air structure through the working component 2. The airflow enhances the flowability of the particles and accelerates the screening. The hot air can quickly remove trace amounts of moisture from the surface of the particles, breaking down the stickiness of the moisture and dispersing the clumps into individual particles, ensuring that the screen holes are not blocked. The fan 204 provides power to drive outside air into the heating box 205. The dust filter 207 isolates dust and impurities from entering the device with the airflow. After being powered, the electric heating rod 206 generates heat radiation to heat the air. The hot air is introduced by the fan 204 through the hose and sprayed out by the nozzle 203. The extension and retraction of the first electric telescopic rod 202 drives the nozzle 203 to move vertically, improving the flexibility of the hot air.

[0017] Furthermore, a second electric telescopic rod 208 is installed in the middle of the inner wall of the housing 1. A movable isolation plate 209 is fixedly connected to the telescopic end of the second electric telescopic rod 208. An isolation filter screen 210 is embedded on the surface of the movable isolation plate 209. The fixed isolation plate 201 and the movable isolation plate 209 form an isolation structure to prevent materials from falling out. The isolation filter screen 210 blocks the materials while ensuring the passage of hot air. The telescopic control of the second electric telescopic rod 208 moves the movable isolation plate 209, which facilitates the falling of materials that have not been screened and prevents accumulation.

[0018] Furthermore, sleeve rods 211 are fixedly connected to the top of both sides of the box 1. Springs 212 are installed at the top of the inner wall of the sleeve rods 211. An extension rod 213 is slidably connected to the inner side of the sleeve rods 211 through a slot. The top of the extension rod 213 abuts against the spring 212. A connecting frame 214 is fixedly connected to the bottom of the extension rod 213. A screen 215 is fixedly connected to the bottom inner side of the connecting frame 214. A first arc-shaped block 216 is fixedly connected to the bottom outer side of the connecting frame 214. The sleeve rods 211, springs 212, and extension rods 213 form an elastic structure that provides a certain top elasticity effect to prevent the connecting frame 214 from being thrown too high and causing damage.

[0019] Furthermore, brackets 217 are fixedly connected to the lower sides of the housing 1. A drive motor 218 is installed at the top of the bracket 217. The drive motor 218 and its output end are connected to a turntable 219 via a shaft key. A transmission rod 220 is rotatably connected to one side of the turntable 219 via a shaft. A C-shaped rod 221 is rotatably connected to the other end of the transmission rod 220 via a shaft. The drive motor 218 provides power to drive the turntable 219 to rotate, so that the transmission rod 220 drives the C-shaped rod 221 to move horizontally back and forth in the slot of the limit frame 222. The auxiliary frame 223 provides auxiliary support, so that the second arc-shaped block 224 follows the back and forth movement.

[0020] Furthermore, the outer side of the C-shaped rod 221 is slidably connected to the limiting frame 222 via a slot. The bottom of the limiting frame 222 is fixedly connected to the box body 1. One end of the C-shaped rod 221 is slidably connected to the auxiliary frame 223 via a slot. The bottom of the auxiliary frame 223 is fixedly connected to the box body 1. The top of the C-shaped rod 221 is fixedly connected to the second arc-shaped block 224. Multiple sets of the second arc-shaped block 224 are provided. The upper surface of the second arc-shaped block 224 abuts against the first arc-shaped block 216. The second arc-shaped block 224 follows the reciprocating movement. During the process of abutting against the first arc-shaped block 216, the connecting frame 214 is continuously moved vertically within the slot of the box body 1, which drives the screen 215 to throw the material up to enhance the screening effect.

[0021] Furthermore, a feed inlet 3 is fixedly connected to the upper surface of the box 1, a first guide plate 4 is fixedly connected to the lower inner wall of the box 1, and a second guide plate 5 is fixedly connected to the bottom of the first guide plate 4. Material is introduced through the feed inlet 3, and the material screened by the screen 215 is discharged through the first guide plate 4, while the material not screened falls onto the second guide plate 5 and is discharged.

[0022] Working principle: In operation, firstly, material is introduced through the feed inlet 3, and the material screened by the screen 215 is discharged through the first guide plate 4. Secondly, the blower 204 provides power to drive outside air into the heating box 205. The dust filter 207 isolates dust and impurities from entering the device with the airflow. After being powered, the electric heating rod 206 generates heat radiation to heat the air. The hot air is guided by the blower 204 through the hose and sprayed out by the nozzle 203. The extension and retraction of the first electric telescopic rod 202 drives the nozzle 203 to move vertically, improving the flexibility of the hot air. The fixed isolation plate 201 and the movable isolation plate 209 form an isolation structure to prevent material from falling out. The isolation filter 210 blocks the material while ensuring the passage of hot air. Thirdly, the drive motor 218 provides power to drive the turntable 219 to rotate, causing the transmission rod 2 to rotate. 20 drives the C-shaped rod 221 to move horizontally back and forth in the slot of the limiting frame 222. The auxiliary frame 223 provides auxiliary support, causing the second arc-shaped block 224 to follow the back and forth movement. During the process of abutting against the first arc-shaped block 216, the connecting frame 214 moves vertically in the slot of the box 1, driving the screen 215 to throw the material up to enhance the screening effect. The sleeve rod 211, spring 212, and extension rod 213 form an elastic structure to provide a certain top elasticity effect, preventing the connecting frame 214 from being thrown too high and causing damage. In the fourth step, the second electric telescopic rod 208 extends and retracts to control the movement of the movable isolation plate 209, which facilitates the falling of unscreened material and prevents accumulation. The unscreened material falls onto the second guide plate 5 and is discharged. This completes the use of a screening device for the production of dehydrated carrot granules.
