Description

Technical Field

[0001] This utility model relates to a conveying device for processing fresh fruit, and in particular to a novel conveying device for drying green plums. Background Technology

[0002] Green plums are rich in nutrients and have a unique taste. They can be eaten fresh or used as a high-quality raw material for processing dried fruit, candied fruit, and plum wine. After harvesting, the surface of green plums often has dust, insect eggs, and pesticide residues attached to it, making washing an essential pre-processing step. However, the surface of washed green plums retains a large amount of free water, which, if not dried in time, will directly jeopardize the quality of subsequent processing and storage safety. Currently, green plum drying commonly uses traditional hot air circulating drying equipment. Its working principle is to use an electric or coal-fired hot air furnace to heat air, and then blow the hot air into the drying chamber through a fan, causing the green plums conveyed by the conveyor belt to gradually lose moisture in a high-temperature environment. Although this type of equipment is widely used, it has many shortcomings in actual production. First, the hot air distribution is extremely uneven, with the temperature near the fan outlet being too high and the temperature too low further away, resulting in uneven drying within the same batch of green plums. Second, the hot air only passes over the surface and cannot penetrate the deeper layers of the stacked green plums, causing a "dry outside, wet inside" phenomenon, which not only prolongs the drying time but also increases energy costs. Therefore, we propose a novel conveying device for drying green plums. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a new type of conveying device for drying green plums.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a novel conveying device for drying green plums, comprising a conveyor belt for conveying green plums, several sets of spaced drying mechanisms mounted above the conveyor belt, each drying mechanism comprising a support frame, a mounting base, an air outlet, a fan assembly, and a heating assembly, the two ends of the support frame spanning the left and right sides of the conveyor belt, the mounting base being fixedly mounted on the support frame, the air outlet being connected to the lower end of the mounting base, the fan assembly and the heating assembly being respectively mounted on the left and right sides of the mounting base, the fan assembly comprising a drive motor and a fan wheel, the fan wheel being disposed within the inner cavity of the mounting base, the heating assembly comprising a hot wire support, a heating wire wound around the hot wire support, the hot wire support being disposed at the middle air inlet of the fan wheel.

[0005] To elaborate further, the heating assembly also includes a limiting connector for fixing the hot wire support. The hot wire support includes a plurality of mica sheets, which are interlocked with each other. The limiting connector is provided with a plurality of limiting grooves for locking the mica sheets.

[0006] To further elaborate, the limiting connector is provided with connecting feet and a partition, and a partition is provided between two adjacent connecting feet. The limiting groove is provided with a locking inlet at the partition.

[0007] To further elaborate, the heating assembly also includes a mounting plate, the connecting foot of the limiting connector is fixedly connected to the mounting plate, and the hot wire bracket is clamped between the mounting plate and the limiting connector.

[0008] To elaborate further, the number of mica sheets is at least three, and each mica sheet has several wire-holding openings on both sides for winding heating wires.

[0009] To elaborate further, the fan assembly also includes a motor mounting bracket, which has several extensions for fixed connection with the mounting base.

[0010] To further elaborate, the air outlet is triangular in shape, with its upper end connected to the mounting base and its lower end perpendicularly facing the conveyor belt.

[0011] To elaborate further, the drying mechanism also includes an outer cover that covers the drive motor on the left side of the mounting base.

[0012] The beneficial effects of this utility model are as follows: By integrating the heating component into the middle air inlet of the impeller, the cold air is preheated before entering the impeller. Then, through the high-speed stirring and forced mixing of the impeller, regardless of whether there are local hot spots on the surface of the heating wire, the air blown out by the air outlet is hot air with a highly uniform temperature. This avoids local overheating or insufficient drying from the source, reduces heat loss, significantly improves thermal efficiency, and effectively solves the problem of uneven drying of the same batch of green plums.

Detailed Implementation

[0019] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0020] Combined with appendix Figure 1 To be continued Figure 5 As shown, a novel conveying device for drying green plums includes a conveyor belt 10 for conveying the green plums. The conveyor belt 10 is made of food-grade stainless steel mesh material, which ensures sufficient support strength and allows hot air to penetrate freely from bottom to top or top to bottom, ensuring that the bottom of the green plums can also be evenly exposed to air. Several sets of spaced drying mechanisms are installed above the conveyor belt 10. These drying mechanisms are equidistantly arranged along the conveying direction. The spacing between adjacent sets can be flexibly adjusted according to the conveying speed and drying temperature, thereby achieving segmented and precise drying of green plums with different moisture contents and avoiding excessive heating at one time that could cause the fruit skin to crack.

[0021] The drying mechanism includes a support frame 20, a mounting base 30, an air outlet 40, a fan assembly 50, and a heating assembly 60. The two ends of the support frame 20 span the left and right sides of the conveyor belt 10. The mounting base 30 is fixedly installed on the support frame 20. The air outlet 40 is connected to the lower end of the mounting base 30. The fan assembly 50 and the heating assembly 60 are respectively installed on the left and right sides of the mounting base 30. The fan assembly 50 includes a drive motor 51 and a fan wheel 52. The fan wheel 52 is located in the inner cavity of the mounting base 30. The fan wheel 52 adopts a multi-blade centrifugal impeller structure with between twenty and thirty blades.

[0022] Combined with appendix Figure 3 and attached Figure 4As shown, the heating assembly 60 includes a heating wire support 61, with a heating wire 62 wound around it. The heating wire support 61 is located at the central air inlet 521 of the impeller assembly 52. ​​Because the heating wire support 61 is located at the central air inlet 521 of the impeller assembly 52, cold air first passes through the heating wire 62 in the center of the impeller assembly 52 to complete heat exchange, and is then sucked in by the impeller assembly 52 and thrown out at high speed, greatly reducing heat loss and significantly improving thermal efficiency. The hot air thrown out by the impeller assembly 52 is blown out through the air outlet 40, and the temperature of the blown hot air is uniform, effectively solving the problem of uneven drying of the same batch of plums.

[0023] The heating assembly 60 also includes a limiting connector 63 for fixing the hot wire support 61. The hot wire support 61 includes a plurality of mica sheets 611, which are interlocked with each other. The limiting connector 63 is provided with a plurality of limiting grooves 631 for holding the mica sheets 611 in place. The mica sheets 611, with their excellent high-temperature resistance and electrical insulation properties, serve as the supporting substrate for the heating wire 62. They can maintain dimensional stability in high-temperature working environments for extended periods, without deformation or loosening due to thermal expansion and contraction, ensuring a constant winding spacing of the heating wire 62 and thus maintaining a uniform heating density. The number of mica sheets 611 is at least three, and each mica sheet 611 has a plurality of wire-holding openings 6111 on both sides for winding the heating wire 62.

[0024] The wire clamp 6111 is specifically a U-shaped or V-shaped groove, the opening width of which is slightly smaller than the wire diameter of the heating wire 62. The heating wire 62 is firmly clamped by the elastic deformation of the mica sheet 611 itself, preventing the heating wire 62 from loosening due to thermal expansion and contraction during long-term use. At the same time, the wire clamp 6111 is equidistantly arranged along the length of the mica sheet 611, ensuring that the spacing between each coil of the heating wire 62 is uniform and consistent, and the heating density is balanced.

[0025] The limiting connector 63 is provided with connecting feet 632 and a partition 633. A partition 633 is provided between two adjacent connecting feet 632. The limiting groove 631 is provided with a locking inlet 634 at the partition 633.

[0026] The heating assembly 60 also includes a mounting plate 64. The connecting feet 632 of the limiting connector 63 are fixedly connected to the mounting plate 64, and the hot wire bracket 61 is clamped between the mounting plate 64 and the limiting connector 63. The mounting plate 64 is a disc-shaped metal component. The surface of the mounting plate 64 is parallel to the air inlet end face of the impeller 52. The connecting feet 632 of the limiting connector 63 are locked to the end face of the mounting plate 64 by screws, so that the hot wire bracket 61 is reliably limited in both the axial and radial directions, and will not be displaced even under the vibration environment generated by the high-speed rotation of the impeller 52.

[0027] The fan assembly 50 also includes a motor mounting bracket 53, which has several extensions 531 for fixed connection with the mounting base 30.

[0028] The air outlet 40 is triangular in shape, with its upper end connected to the mounting base 30 and its lower end perpendicularly facing the conveyor belt 10. This triangular design allows the hot air to gradually decrease in speed and gradually recover in static pressure as it enters the large-section outlet from the small-section inlet, forming a wide and gentle laminar flow curtain. This avoids physical damage to the plum pulp caused by high-speed direct airflow and ensures that the hot air can evenly cover the entire width of the material on the conveyor belt 10 without leaving any dead zones.

[0029] The drying mechanism also includes an outer cover 70, which covers the drive motor 51 on the left side of the mounting base 30. The outer cover 70 is a cylindrical protective shell with one open end, which completely encloses the drive motor 51 inside. This not only prevents water vapor overflowing during the plum drying process from corroding the motor housing and wiring terminals, but also reduces the transmission of noise generated by the motor during high-speed operation to the external environment. At the same time, the outer cover 70 has several waist-shaped heat dissipation holes on its cylindrical wall, which takes into account the ventilation and heat dissipation needs of the motor itself while ensuring the protective effect.
