Description

Technical Field

[0001] The utility model relates to the technical field of sweet potato preservation devices, in particular to a device for prolonging the storage period of sweet potatoes. Background Art

[0002] Sweet potato is an important food and cash crop. Its storage and preservation as well as extended shelf life are of great significance to ensuring food supply and industrial development. At present, the common method to extend the shelf life of sweet potato is to spray chitosan solution on the surface of sweet potato. Chitosan solution has good antibacterial and preservation effects, and can inhibit the growth of microorganisms on the surface of sweet potato to a certain extent, thereby extending the shelf life of sweet potato.

[0003] However, this method has obvious defects. On the one hand, it is difficult to ensure that the chitosan solution fully covers the surface of the sweet potato by spraying, and uneven spraying is prone to occur, resulting in the failure to fully protect the surface of some sweet potatoes. On the other hand, the solution needs to be naturally dried after spraying. This process is inefficient, time-consuming, and greatly affected by environmental factors, which is not conducive to large-scale sweet potato preservation. In order to solve these problems, there is an urgent need for a device that can more efficiently and comprehensively treat sweet potatoes to extend the shelf life. Utility Model Content

A rotating shaft 4 is rotatably arranged on the upper end connecting the front and rear side walls of the immersion tank 1. A motor 5 for driving the rotation of the rotating shaft 4 is fixedly arranged on the side surface of the immersion tank 1. A plurality of rectangular frames 6 are fixedly arranged on the rotating shaft 4. The size of the rectangular frame 6 matches the arc-shaped inner bottom surface of the immersion tank 1. A number of rake teeth 7 are fixedly arranged on the inner side of the side of the rectangular frame 6 away from the rotating shaft 4. A gantry 8 is fixedly arranged at the upper end of the belt discharging mechanism 3, and a drying mechanism is arranged at the upper end of the gantry 8.

[0030] In this embodiment, as a preferred technical solution, the drying mechanism includes a hot air blower 9 fixedly arranged at the upper end of the gantry 8. One end of the air outlet of the hot air blower 9 extending into the interior of the gantry 8 is fixedly connected and provided with a number of air outlet pipes 10, and a number of air outlets 11 are arranged at the bottom of the air outlet pipes 10.

[0031] It should be noted that both the belt feeding mechanism 2 and the belt discharging mechanism 3 in this embodiment are mature existing technologies. Their structures generally include brackets, rollers, driving motors and belts. Due to their structural relationships and usage scenarios being relatively common and mature, they will not be described in detail in this solution.

[0032] In this embodiment, as a preferred technical solution, rubber deflector plates 12 for correcting the conveying position of sweet potatoes are fixedly arranged on both inner side walls at one end of the gantry 8 close to the immersion tank 1. Both rubber deflector plates 12 are inclined inward. A cross bar 13 is fixedly arranged at the center of the interior of the gantry 8 connecting both side walls, and a number of rubber deflector plates two 14 for tumbling sweet potatoes are fixedly arranged at the bottom of the cross bar 13.

[0033] The working principle of the device for extending the storage period of sweet potatoes of the present utility model is as follows: The device for extending the storage period of sweet potatoes mainly conveys sweet potatoes to the immersion tank 1 through the belt feeding mechanism 2, so that the sweet potatoes are immersed in the chitosan solution. After soaking for a certain period of time, the motor 5 drives the rotation of the rotating shaft 4, driving the rectangular frame 6 and the rake teeth 7 fixed on the rotating shaft 4 to rotate. The rake teeth 7 fish out the soaked sweet potatoes from the immersion tank 1 and place them on the belt discharging mechanism 3. Subsequently, the sweet potatoes are conveyed to the gantry 8. The hot air blower 9 blows hot air through the air outlet pipes 10 and the air outlets 11 to quickly dry the sweet potatoes. The rubber deflector plates 12 correct the conveying position of the sweet potatoes, and the rubber deflector plates two 14 at the bottom of the cross bar 13 tumble the sweet potatoes to make the drying more uniform.

[0034] The working process of the device for extending the storage period of sweet potatoes of the present utility model is as follows:

[0035] 1. Equipment preparation: The motor 5, the hot air blower 9, the belt feeding mechanism 2 and the belt discharging mechanism 3 are connected to an external power supply.

[0036] 2. Conveying sweet potatoes: Place the sweet potatoes on the belt feeding mechanism 2, and the sweet potatoes are conveyed to the soaking pool 1 as the belt moves.

[0037] 3. Soaking treatment: After the sweet potatoes enter the soaking pool 1, soak them in the chitosan solution for a period of time to ensure that the surface of the sweet potatoes is fully in contact with the solution.

[0038] 4. Fishing out and discharging: After the soaking is completed, the motor 5 drives the rotating shaft 4 to rotate, and the rake teeth 7 on the rectangular frame 6 fish out the sweet potatoes from the soaking pool 1 onto the belt discharging mechanism 3.

[0039] 5. Air-drying treatment: The sweet potatoes are conveyed by the belt discharging mechanism 3 to the gantry 8. During the process of passing through the gantry 8, the rubber flap 12 corrects the conveying position of the sweet potatoes, and the hot air blown out by the hot air blower 9 passes through the air outlet pipe 10 and the air outlet 11 to quickly air-dry the sweet potatoes. At the same time, the rubber flap two 14 at the bottom of the cross bar 13 tumbles the passing sweet potatoes, causing the sweet potatoes to turn over and making the surface drying more uniform.

[0040] 6. Collection and preservation: The air-dried sweet potatoes are conveyed to the designated position for collection and preservation.

[0041] The above describes the present utility model and its implementation manners. This description is not restrictive.
