Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sunflower seed production equipment, specifically a drying device for producing large-plate sunflower seeds. Background Technology
[0002] Large-shelled watermelon seeds, also known as "black watermelon seeds" or "black melon seeds," are the seeds of the watermelon variety, specifically the seed watermelon, a member of the Cucurbitaceae family. They are primarily produced in certain regions of China, such as Minqin County in Wuwei City, Gansu Province, and the suburbs of Lanzhou City, as well as Gaolan, Yongdeng, Jingyuan, and Huining counties. These regions, with their unique soil, sunlight, and climate conditions, are ideal for the growth of large-shelled watermelon seeds. These seeds are characterized by their large size, thin skin, flat surface, loose kernel, thick flesh, glossy black color, and lingering aroma. Large-shelled watermelon seeds can be eaten directly or processed into various types of seed products, such as roasted seeds and boiled seeds. Spiced melon seeds, among others, require drying after boiling during the production process. This is to prevent the seeds from sticking together, to prevent mold and spoilage due to excessive residual moisture, and to make the seeds crispier and improve their texture as the moisture evaporates during drying. Currently, most sun-drying is done in the shade, but this method is inefficient for large-scale production, requires a large area, and sometimes results in sticking, necessitating regular manual turning. Therefore, there is a need to invent a drying device for boiled melon seeds. Utility Model Content
[0003] To address the above technical problems, this utility model provides a drying device for the production of large-format sunflower seeds.
[0004] To solve the above-mentioned technical problems, the present invention provides a drying device for producing large-format sunflower seeds, comprising a box body. A feeding hopper is fixedly connected to the top of the box body, and a support leg is fixedly connected to the bottom. Two interlocking towel rollers are rotatably connected to the lower part of the feeding hopper. One of the towel rollers is drivenly connected to the output end of a second motor. An air outlet is also fixedly connected to the top of the box body. A first motor is fixedly connected to one side of the box body. The output end of the first motor extends through the box body and is fixedly connected to a main shaft. A stirring rod is fixedly connected to the main shaft. A mesh funnel is fixedly connected to the bottom of the box body. An airlock and an auger are fixedly connected to the bottom of the box body. The output end of the airlock corresponds to the input end of the auger. A hot air blower is also fixedly connected to the bottom of the box body. The output end of the hot air blower extends through the box body and is located between the mesh funnel and the bottom of the box body. The bottom of the box body has a structure that is high in the center and low around the edges.
[0005] Furthermore, the mesh size of the mesh funnel is 0.5 cm.
[0006] Furthermore, a drain pipe is fixedly connected to the bottom of the box, and a valve is fixedly connected to the drain pipe.
[0007] This utility model has the following advantages compared with the prior art:
[0008] 1. This utility model uses a towel roller to initially dry the large sunflower seeds added to the chamber. Then, the motor drives the main shaft and stirring rod to rotate and turn the large sunflower seeds to prevent them from sticking together. At the same time, the hot air output from the hot air blower dries the large sunflower seeds from bottom to top, which is more efficient. By setting a drain pipe at the bottom of the chamber, the accumulation of liquid at the bottom of the chamber is prevented and excess liquid can be discharged in time. Attached Figure Description

[0012] The present invention will be further described below with reference to the accompanying drawings.
[0013] like Figures 1 to 2 The drying device for producing large-sized sunflower seeds shown includes a housing 1. A feeding hopper 2 is fixedly connected to the top of the housing 1, and four support legs 12 are fixedly connected to the bottom. Two towel rollers 3, which are meshed with each other by gears, are rotatably connected to the lower part of the feeding hopper 2. One of the towel rollers 3 is connected to the output end of a second motor 14. Two air outlets 13 are also fixedly connected to the top of the housing 1. A first motor 4 is fixedly connected to one side of the housing 1. The output end of the first motor 4 extends through the housing 1 and is fixedly connected to a main shaft 5. A stirring rod 6 is fixedly connected to the main shaft 5 to stir and tumble the large-sized sunflower seeds inside the housing 1. The mixing chamber 1 has a mesh funnel 7 fixedly connected to the bottom, which serves to drain water and ventilate. A windproof device 9 and an auger 10 are fixedly connected to the bottom of the chamber 1. The output end of the windproof device 9 corresponds to the input end of the auger 10. The windproof device 9 serves to unload and lock air. A hot air blower 8 is also fixedly connected to the bottom of the chamber 1. The output end of the hot air blower 8 passes through the chamber 1 and extends inward. The output end of the hot air blower 8 is located between the mesh funnel 7 and the bottom of the chamber 1. The bottom of the chamber 1 has a structure that is high in the center and low around the edges to prevent liquid from flowing into the auger 10 through the windproof device 9. Both the windproof device 9 and the auger 10 are driven by their own motors.
[0014] In order to drain the large sunflower seeds while preventing them from falling into the lower part of the mesh funnel 7, the mesh size of the mesh funnel 7 is 0.5cm.
[0015] In order to drain the liquid accumulated at the bottom of the box 1 due to water leakage in a timely manner, a drain pipe 11 is fixedly connected to the bottom of the box 1, and a valve is fixedly connected to the drain pipe 11.
[0016] It should be noted that the hot air blower 8, airlock 9, and auger 10 in this embodiment are existing devices, and their specific structures will not be described in detail.
[0017] The working process of this embodiment is as follows:
[0018] During operation, the first motor 4, the second motor 14, and the hot air blower 8 are turned on. At this time, the airlock 9 and the auger 10 are not running. After cooking, an appropriate amount of large-sized sunflower seeds are scooped out and enter the chamber 1 through the feed hopper 2. During feeding, the surface moisture of the large-sized sunflower seeds is initially wiped dry by two relatively rotating towel rollers 3. Then, the large-sized sunflower seeds enter the chamber 1, where the stirring rod 6 stirs and turns them. At the same time, the hot air blower 8 continuously outputs hot air into the chamber 1. The hot air passes through the mesh funnel 7 to continuously dry the large-sized sunflower seeds above the mesh funnel 7. The air is finally discharged from the air outlet 13. After the surface of the large sunflower seeds is dried, the airlock 9 and the auger 10 are operated. The large sunflower seeds enter the auger 10 through the airlock 9 and are finally sent to the next process by the auger 10. During this period, the valve on the drain pipe 11 is opened to discharge the liquid accumulated at the bottom of the box 1 due to drainage. After the feeding is completed, during the drying process of the large sunflower seeds, the hot air generated by the hot air blower 8 can dry the towel roller 3 so as to play a preliminary drying role for the next batch of large sunflower seeds and realize the reuse of the towel roller 3.
