Description

Technical Field

[0001] This invention relates to the field of longan fruit soaking and washing and shaking and rubbing technology, specifically to an integrated device for soaking and washing longan fruit and shaking and rubbing and its application method. Background Technology

[0002] Dried longan is a popular and nutritious food with a large consumer market throughout my country. Longan ripens in the hot summer months, has a short harvest period, and is not very durable, leading to high sales pressure and volatile prices. Compared to fresh longan, dried longan can be stored for a longer time, is easier to transport, expands the sales reach, and can be processed into various value-added products, further increasing farmers' income. Currently, there are few dried longan processing enterprises in my country, and they are mostly small-scale, scattered in longan-producing areas such as Guangdong, Guangxi, and Fujian. Processing is still largely done by individual, decentralized farmers, resulting in a disorganized and haphazard approach. The amount processed varies depending on the sales of fresh longan; less is processed when sales are good, and more is processed when sales are poor.

[0003] The processing steps for dried longan are: fruit selection, cutting, soaking, rubbing off sand and peeling, drying, yellowing, grading, and packaging. Soaking and rubbing off sand and peeling are preliminary steps for drying fresh longan. Their functions are to soften the peel and remove surface impurities, remove surface wax to increase the capillary channels for water evaporation, and powder the surface of the fruit, providing the prerequisites and guarantees for efficient drying to produce high-quality, excellent-looking dried longan.

[0004] Currently, while drying, grading, and packaging equipment are in use in enterprises, the soaking, especially the sand-washing and peeling process, still largely relies on traditional bamboo-woven shaking baskets, entirely manual labor. This results in serious problems such as outdated production equipment, difficulty in controlling processes and technical standards, low efficiency, and high costs, significantly hindering technological progress and industry development in longan drying. Therefore, we provide a longan fruit soaking and sand-washing equipment and its application method to solve these problems. Summary of the Invention

The electrical control box 11 is electrically connected to the drive mechanism 5, the automatic sand-adding mechanism 7, and the automatic water-injecting mechanism 9, respectively.

[0059] S3: Water immersion: Water is injected into the rotating barrel structure 3 through the automatic water injection mechanism 9, and the barrel is soaked for a specified time;

[0060] S4: After soaking, start the drive mechanism 5 to drive the rotating barrel structure 3 to rotate 180 degrees to drain the water and enter the water tank. After draining, the rotating barrel structure 3 rotates 180 degrees to return to its original position.

[0061] S5: Adding sand: The automatic sand adding mechanism 7 rotates 180 degrees to add sand into the rotating barrel structure 3. After the sand adding is completed, the automatic sand adding mechanism 7 returns to its original position.

[0062] S6: Shaking and rubbing: Start the drive mechanism 5 to drive the rotating barrel structure 3 to rotate at the set frequency and time to shake and rub the skin;

[0063] S7: Stop and unload: Open the lid of the rotating barrel structure 3, unload the fresh longan fruit and let it fall into the discharge hopper assembly with screen holes, separate the sand and longan fruit and put them into baskets, wait for drying, complete the soaking and shaking of the fresh longan fruit and wait for the next cycle.

[0064] A specific embodiment of the present invention is applied as follows:

[0065] Please refer to Figure 1 and Figure 5 As shown: A device integrating soaking, washing, shaking, and peeling of fresh longan fruit includes a base plate 1. First mounting frames 2 are symmetrically fixed to opposite sides of the top of the base plate 1. A rotating barrel structure 3 is rotatably connected between the two sets of first mounting frames 2. A mounting plate 4 is fixed between the two sets of first mounting frames 2. A drive mechanism 5 is fixed to the top of the mounting plate 4. The drive mechanism 5 is connected to the rotating barrel structure 3 and drives the rotating barrel structure 3 to rotate. Second mounting frames 6 are fixed to the top of the first mounting frames 2. A rotatable automatic... The sand-adding mechanism 7 is located above the rotating barrel structure 3 and adds sand to the rotating barrel structure 3 at regular intervals. A water tank 8 is provided on the top of the bottom plate 1 and is located below the rotating barrel structure 3. The water tank 8 is connected to an automatic water-filling mechanism 9, which is located on one side of the rotating barrel structure 3 and fills the rotating barrel structure 3 with water at regular intervals. A discharge hopper assembly 10 is installed on the top of the mounting plate 4. The discharge hopper assembly 10 is located below the rotating barrel structure 3 and in front of the water tank 8. The discharge hopper assembly 10 is provided with sieve holes.

[0066] Please refer to Figure 5 , Figure 6 , Figure 8 and Figure 9As shown: The rotating barrel structure 3 includes a rotating barrel 31. The outer wall of the rotating barrel 31 has a longan-shaped inlet, and a barrel cover assembly 32 is installed at the longan-shaped inlet. The outer wall of the rotating barrel 31 has a sand inlet 33 that cooperates with the automatic sand-adding mechanism 7. Fixed shafts 34 are symmetrically fixed to opposite ends of the rotating barrel 31. A first bearing 35 with a seat is installed on the top of the first mounting bracket 2. The fixed shafts 34 and the first bearing 35 are rotatably connected. The sand inlet on the rotating barrel can also be used as a drainage hole. The opening size of the sand inlet 33 gradually decreases from the outer wall of the rotating barrel 31 towards the inner wall, and the opening size of the inner wall of the sand inlet 33 is 3-5mm. The inner wall of the rotating barrel 31... Several sets of ribs 36 are fixed at equal angles along the axial direction of the rotating barrel 31. The ribs 36 are made of silicone strips and have a rectangular cross-section. The two corners of the ribs 36 away from the inner wall of the rotating barrel 31 are chamfered at 45 degrees. The 45-degree chamfer of the adjacent ribs 36 can improve the friction of the longan during the shaking and rubbing process, reduce the rotation speed of the rotating barrel 31, and avoid damage to the longan due to excessive centrifugal impact. There are gaps between the two ends of the ribs 36 and the two ends of the rotating barrel 31. There is a gap 37 between two adjacent sets of ribs 36. The gap 37 is 1-2mm in size, so that during the drainage process, the soaking water accumulated at the chamfer of the lower ribs can be completely discharged through the gap, thus making the soaking water drain more thoroughly.

[0067] Please refer to Figure 1 and Figure 5 As shown: The drive mechanism 5 includes a drive motor 51, a reducer 52, a drive sprocket 53, a driven sprocket 54, and a chain 55. The reducer 52 is mounted on the mounting plate 4. The input shaft of the reducer 52 is connected to the drive motor 51, and the output shaft of the reducer 52 is connected to the drive sprocket 53. The driven sprocket 54 is mounted on the outer wall of the fixed shaft 34. The drive sprocket 53 and the driven sprocket 54 are connected by a chain 55.

[0068] Please refer to Figure 1 , Figure 4 and Figure 10 As shown: The automatic sand-adding mechanism 7 includes two sets of second mounting frames 6 arranged symmetrically. The automatic sand-adding mechanism 7 includes two sets of second bearings 71 with seats. The two sets of second bearings 71 with seats are symmetrically mounted on the top of the second mounting frames 6. A hollow rotating shaft 72 is rotatably connected between the two sets of second bearings 71. A sand-collecting port is opened on the top of the rotating shaft 72. An L-shaped bracket 74 is mounted on the top of one set of second mounting frames 6. A rotary cylinder 73 is mounted on the top of the second mounting frame 6 through the L-shaped bracket 74. A connecting shaft 76 is connected to the output end of the rotary cylinder 73. The connecting shaft 76 is connected to one end of the rotating shaft 72 through a coupling 75.

[0069] Please refer to Figure 1 , Figure 2 and Figure 3As shown: The automatic water filling mechanism 9 includes a water pump 91, which is fixed to the top of the water tank 8 and connected to the water tank 8. The water pump 91 is connected to a water hose 92. A telescopic cylinder 93 is installed on the top of the second mounting bracket 6. A water inlet block 94 is fixed to the telescopic end of the telescopic cylinder 93. One end of the water hose 92 is connected to the water inlet block 94. A leak-proof rubber block 95 is installed on the side of the water inlet block 94 near the rotating barrel structure 3 by bolts. A water inlet pipe assembly 96 is provided on the side wall of the rotating barrel structure 3, which is in close contact with the leak-proof rubber block 95.

[0070] Please refer to Figure 7 As shown: The water inlet pipe assembly 96 includes four sets of guide screws 961. A limiting disk 962 is fixedly connected to the outer wall of the four sets of guide screws 961. A water inlet pipe 963 is slidably connected through the inner cavity of the limiting disk 962. One end of the water inlet pipe 963 passes through the side wall of the rotating barrel structure 3. The limiting effect of the guide screws and the limiting disk enables the water inlet pipe to move in a straight line, so as not to deviate.

[0071] Please refer to Figure 7 As shown: A limiting sleeve is fixed to the outer wall of the water inlet pipe 963, and a spring 964 is sleeved on the outer wall of the water inlet pipe 963. The spring 964 is located between the limiting sleeve and the side wall of the rotating barrel structure 3, so that the water inlet pipe can automatically reset under the action of the spring's restoring force after water is filled.

[0072] Please refer to Figure 7 As shown: The water inlet pipe 963 has a water inlet on its side wall and the end of the water inlet pipe 963 is a sealed structure. The rotating barrel structure 3 has an insertion interface on its side wall that matches the end of the water inlet pipe 963, so that when the water inlet pipe is separated from the rotating barrel structure, the end of the water inlet pipe can seal the rotating barrel structure.

[0073] Please refer to Figure 7 As shown: Two nuts are screwed onto the outer wall of the guide screw 961, and the limiting plate 962 is set between the two nuts to lock and fix the limiting plate, ensuring the stability of the limiting plate;

[0074] Please refer to Figure 1 As shown: An electrical control box 11 is installed on the right side of the base plate 1 via a connecting rod. The electrical control box 11 is electrically connected to the drive mechanism 5, the automatic sand adding mechanism 7, and the automatic water injection mechanism 9, respectively. The automatic control and efficient production of batch production are achieved through the control system inside the electrical control box.

[0075] When using the equipment:

[0076] 1) Power on and set the operating parameters, and check whether the sand inlet 33 of the rotating barrel 31, the rotating cylinder 73 and the telescopic cylinder 93 are in their original positions;

[0077] 2) Open the barrel cover assembly 32 of the longan inlet of the rotating barrel 31, then pour fresh longan fruit into the rotating barrel 31, and then add a certain amount of sand into the rotating shaft 72 through the sand inlet;

[0078] 3) Water immersion: The controller in the electrical control box 11 controls the telescopic cylinder 93 to start working. The piston rod of the telescopic cylinder 93 drives the water inlet block 94 and the leak-proof rubber block 95 to extend from their original positions and press against the water inlet pipe 963. The water inlet pipe 963 moves along the limit plate 962 to start compressing the spring 964 and inserting into the side wall of the rotating barrel 31. Then the water pump 91 starts working, pumping water through the water hose 92 into the water inlet block 94 and the leak-proof rubber block 95 and into the water inlet pipe 963, thereby injecting water into the rotating barrel 31. After a predetermined water injection period, the water pump 91 is turned off, and the water inlet block 94 and the leak-proof rubber block 95 are retracted to their original positions by the telescopic cylinder 93, so that the water inlet pipe 963 returns to its original position under the restoring force of the spring 964.

[0079] 4) After soaking for a period of time, start the drive motor 51. The drive motor 51 rotates and drives the drive sprocket 53 to rotate after being reduced by the reducer 52. This drives the rotating barrel 31 to rotate 180 degrees through the chain 55 and the driven sprocket 54, thereby draining the soaking water into the water tank 8. After the drainage is completed, the drive motor 51 drives the rotating barrel 31 to return to its original position.

[0080] 5) Adding sand: Start the rotary cylinder 73, which drives the rotating shaft 72 to rotate 180 degrees, thereby pouring the fine sand in the rotating shaft 72 into the rotating barrel 31 through the sand inlet 33; after the sand is added, the rotary cylinder 73 drives the rotating shaft 72 back to its original position, completing the sand adding operation;

[0081] 6) Shaking and rubbing: After sanding is completed, the drive motor 51 is started. The drive motor 51 drives the active sprocket 53 to rotate through the reducer 52, and drives the driven sprocket 54 to rotate through the chain 55. This drives the rotating barrel 31 to rotate at the set frequency and time to shake and rub the longan. During the shaking and rubbing process, the friction of the ribs 36 and gaps 37 inside the rotating barrel 31 is enhanced, making the longan fruit turn more quickly and thoroughly, thus improving the shaking and rubbing effect of the longan.

[0082] 7) Stop and unload: After the peeling is completed, rotate the longan inlet of the rotating barrel 31 to the top of the discharge hopper assembly 10, and then open the barrel cover assembly 32 of the rotating barrel 31 to discharge the longan and sand into the discharge hopper assembly 10. The discharge hopper assembly 10 is set at a downward tilt angle and has sieve holes to separate the sand and longan particles and pack them into baskets for drying, thus completing the washing and peeling of the fresh longan fruit.
