Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable sorting technology, specifically to a fruit and vegetable sorting device that can be dried. Background Technology

[0002] In the fruit and vegetable processing industry, sorting and drying are pre-treatment steps to ensure product quality. Traditional fruit and vegetable sorting devices mostly use a single fixed screen structure, relying on gravity or simple vibration for screening, which makes it difficult to perform multi-level precise sorting based on differences in particle size and shape. Moreover, sorting and drying functions are independent, requiring sorted fruits and vegetables to be transferred to separate drying equipment, making the process cumbersome and prone to damage. In addition, static drying methods result in uneven evaporation of moisture from the surface of fruits and vegetables, affecting quality, while screen replacement requires disassembling the entire structure, which is complex, time-consuming, and difficult to adapt to the sorting needs of different batches. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides the following technical solution: A fruit and vegetable sorting device capable of being dried, comprising a shell, a sieving section, a drying section, and a support; the support is mounted on the shell; the sieving section is mounted on the support and is used for sorting; the sieving section includes a sieving bearing ring rotatably mounted on the support, and multiple sieving guide rods are fixedly mounted axially on the sieving bearing ring 1, sieving mesh 1, sieving mesh 2, sieving mesh 3, sieving mesh 4, and sieving bearing ring 2 detachably mounted on the sieving guide rods via sieving bolts; the sieving bearing ring 1 and sieving bearing ring 2 are in frictional engagement with sieving rollers rotatably mounted on the support; the drying section includes a drying guide column fixedly mounted on the shell, and a drying shell is adjustablely mounted on the drying guide column via drying limiting bolts; a drying resistance wire 1 and a drying resistance wire 2 are mounted inside the drying shell, and a drying fan blade is rotatably mounted on one side of the drying resistance wire 1 and the drying resistance wire 2, and the drying fan blade is fixedly mounted on the output shaft of the drying motor.

[0004] Furthermore, a screening hopper 1 is provided below the screening screen 1, a screening hopper 2 is provided below the screening screen 2, a screening hopper 3 is provided below the screening screen 3, and a screening hopper 4 is provided below the screening screen 4.

[0005] Furthermore, a screening feed hopper is rotatably mounted on the screening support ring, and the screening feed hopper is fixedly mounted on the support.

[0006] Furthermore, the inner walls of screening mesh one, screening mesh two, screening mesh three, and screening mesh four are each provided with multiple screening guide plates. The screening guide plates are distributed in a spiral pattern along their inner walls, and when they rotate, the surface of the screening guide plates generates an oblique thrust on the material. According to the spiral direction, the material is controlled to move towards the front end of screening mesh one.

[0007] Furthermore, each of the screening meshes 1, 2, 4, and 3 is provided with sorting holes, and the diameter of the sorting holes increases sequentially from the screening support ring 1 to the screening support ring 2.

[0008] Furthermore, screening collection boxes are provided below screening hoppers one, two, three, and four, and collection bins are provided on the screening collection boxes. The collection bins correspond one-to-one with screening hoppers one, two, three, and four.

[0009] Furthermore, air inlets are provided on both bottom surfaces of the drying shell, and the drying shell is made of metal.

[0010] The advantages of this utility model compared with the prior art are:

[0011] 1. This utility model adopts a multi-layer screening mesh structure, with the mesh apertures of each layer designed in a gradient manner. Combined with the spiral guide plates on the inner wall, the mesh rotates, propelling fruits and vegetables axially. This allows fruits and vegetables of different particle sizes to fall through the corresponding mesh apertures, solving the problem of insufficient sorting precision in traditional single-mesh systems. This design not only extends the contact time between the material and the mesh apertures but also adapts to the movement characteristics of fruits and vegetables of different shapes, enabling fine grading of various fruits and vegetables.

[0012] 2. The screening and drying sections are integrated into the same device. During the sorting process, the position of the drying shell can be adjusted, and the fruits and vegetables in the screening mesh can be dried simultaneously using the hot air circulation system, eliminating the need to transfer them to separate equipment. Dynamic hot air penetrates the material layer, making moisture evaporation more uniform, while reducing the number of material transfers, lowering the damage rate, shortening the process flow, and achieving highly efficient "sorting and drying simultaneously" operation.

[0013] 3. The screens are modularly installed using guide rods and bolts, eliminating the need to disassemble the entire structure for replacement. This allows for quick switching between screens of different apertures, adapting to the sorting needs of multiple batches and sizes of fruits and vegetables. The drying outer shell's height can be adjusted via guide pillars and limit bolts, precisely matching the number of screen layers and material stacking thickness to meet the drying requirements of fruits and vegetables with varying moisture contents.

[0014] 4. The screening hopper and the collection bin of the collection box correspond one-to-one, allowing sorted fruits and vegetables to fall directly into their respective bins, reducing manual sorting workload. The drying shell and fan blades are made of high-temperature resistant metal materials, maintaining structural stability in high-temperature environments and preventing component deformation and damage. At the same time, the hot air circulation system improves drying efficiency and ensures long-term stable operation of the equipment. Attached Figure Description

These guide plates 102 are spirally distributed along their inner walls. When screening mesh 101, screening mesh 2 109, screening mesh 3 110, and screening mesh 4 111 rotate, the surface of the guide plates 102 exerts an oblique thrust on the material. Based on the spiral direction, the material is controlled to move towards the front end of screening mesh 101.

[0033] like Figures 1 to 10 As shown, the working principle of the fruit and vegetable sorting device that can be dried is as follows:

[0034] The fruits and vegetables to be sorted are fed into the screening mesh 101 through the screening hopper 116. The screening motor 117 is turned on, which drives the screening roller 107 to rotate. The rotation of the screening roller 107 causes the screening support ring 103, screening mesh 101, screening mesh 2 109, screening mesh 3 110, screening mesh 4 111, and screening support ring 2 104 to rotate together. When screening mesh 101, screening mesh 2 109, screening mesh 3 110, and screening mesh 4 111 rotate, the screening devices inside them... The guide plate 102 drives the fruit and vegetable products to move from the screening screen 101 to the screening support ring 204. During this process, the sorting holes of different apertures on the screening screen 101, screening screen 2 109, screening screen 4 111, and screening screen 3 110 sort and screen the fruits and vegetables inside. The screened fruits and vegetables fall into the corresponding collection bins on the screening collection box 108 through the screening hopper 112, screening hopper 2 113, screening hopper 3 114, and screening hopper 4 115.

[0035] During the screening process, the drying shell 205 is raised to a predetermined position, and the position of the drying shell 205 is restricted by the drying limit bolt 206, so that the drying shell 205 is in the predetermined position. The drying motor 201, drying resistance wire one 203, and drying resistance wire two 204 are turned on. The rotation of the drying motor 201 drives the drying fan blades 202 to make air flow from the direction of the drying motor 201 to the direction of the drying shell 205. The drying resistance wire one 203 and drying resistance wire two 204 are connected to the power supply to generate heat. The flowing air carries the heat through the screening bearing ring two 104 into the screening screen one 101, screening screen two 109, screening screen three 110, and screening screen four 111, so as to quickly dry the fruits and vegetables inside.

[0036] When replacing the screening mesh 101, screening mesh 2 109, screening mesh 3 110, and screening mesh 4 111 with different sorting hole diameters according to different products, the specific operation is as follows: First, loosen the screening bolt 105 to remove it. Then, remove the screening bearing ring 2 104, screening mesh 4 111, screening mesh 3 110, screening mesh 2 109, and screening mesh 101 from the screening guide rod 106 for replacement.
