Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of millet processing equipment, specifically a drying device for millet processing. Background Technology
[0002] Yellow millet generally refers to the hulled grains of millet or sorghum. Millet grains are typically smaller and glutinous; after hulling, they become what we commonly call yellow millet or large yellow millet, mainly used for making cakes and brewing wine. Sorghum grains are typically slightly larger and come in both non-glutinous and japonica varieties; after hulling, they are often called millet or sorghum rice (non-glutinous), and sometimes also generally referred to as yellow millet (glutinous). Both have similar harvesting and processing processes. After threshing and cleaning, both require drying for subsequent storage. The traditional method involves spreading the grains thinly on a clean, well-ventilated drying ground (cement floor, canvas, etc.) and air-drying them for several days in sunny weather, taking care to protect them from rain, birds, and livestock. Nowadays, grain dryers are used for drying. Rapidly reducing moisture under controlled temperature and humidity is efficient and unaffected by weather, but it is costly and can affect quality, especially when dealing with glutinous millet. Glutinous millet is almost entirely composed of amylopectin, which has a large molecular weight and loose structure. When using a grain dryer for rapid drying, high temperatures and strong ventilation are often used, causing the outer layer of moisture to evaporate and shrink quickly, while the internal moisture remains high. The starch granules on the surface of the grain expand, rupture, and partially gelatinize. After cooling, the gelatinized starch rearranges into a denser, harder structure (retrogradation), resulting in a harder texture, reduced water absorption, and decreased gloss. Therefore, there is a need to invent a device suitable for drying millet to meet this requirement. Utility Model Content
[0003] To address the above technical problems, this utility model provides a drying device for processing millet.
[0004] To solve the above-mentioned technical problems, the present invention provides a drying device for millet processing, comprising a frame, with casters fixedly connected to the bottom of the frame, the frame being divided into a front frame and a rear frame, the top of the front frame and the rear frame being fixedly connected by a top rod, the bottom of the front frame and the rear frame being fixedly connected by a bottom rod, the front frame having a plurality of front grooves spaced apart, the rear frame having a plurality of rear grooves correspondingly provided, a support rod being fixedly connected between the bottom of the front groove and the corresponding rear groove on the same side, a limit plate being fixedly connected to the rear side of the rear groove, the outer side of the frame being covered with gauze, the top of the gauze at the front end of the frame being fixedly connected to the front frame, and a pull rod being fixedly connected to the bottom end, a grain tray of corresponding size being provided in the space formed by the front groove and the corresponding rear groove, and a separating device being provided on the front frame.
[0005] Furthermore, the dispensing device includes a plurality of toothed rods and dispensing teeth. The toothed rods are spaced apart at the top of the front groove and connected to the front frame. A plurality of dispensing teeth are spaced apart at the bottom of the toothed rods. The dispensing teeth are made of rubber.
[0006] Furthermore, the vertical spacing between the front grooves is not less than 30cm.
[0007] Furthermore, the bottom of the grain tray is made of mesh with a mesh count of less than 20.
[0008] Furthermore, the frame is square with the same length and width, and the grain drawer is also square.
[0009] This utility model has the following advantages compared with the prior art:
[0010] This invention, by incorporating a separating device, automatically separates the millet into a wave-like shape during the grain drawer placement process. This increases the contact area between the millet and air within the drawer, allowing for faster drying and preventing the millet in the center from drying too slowly. The multi-layer design increases the amount of millet that can be dried at one time without affecting air circulation, making it more practical. The gauze covering the outside of the frame serves to protect against birds and livestock during the drying process, while also preventing larger debris from entering the millet.

[0015] The present invention will be further described below with reference to the accompanying drawings.
[0016] like Figures 1 to 3The drying device for millet processing shown includes a frame with casters 9 fixedly connected to the bottom for easy movement. The frame is covered with gauze 10 on both sides. The frame is divided into a front frame 1 and a rear frame 2. The tops of the front frame 1 and the rear frame 2 are fixedly connected by a top rod 6, and the bottoms of the front frame 1 and the rear frame 2 are fixedly connected by a bottom rod 7. The front frame 1 has several front grooves 101 spaced apart, and the rear frame 2 has several corresponding rear grooves 201. In this embodiment, four sets of grooves are used. A support rod 3 is fixedly connected between the bottom of the front groove 101 and the bottom of the corresponding rear groove 201 on the same side. The bottom of the lowest front groove 101 and the bottom of the rear groove 201 can be connected by the bottom rod 7 instead of the support rod 3. A limiting plate 202 is fixedly connected to the rear side to limit the grain drawer 8 and prevent damage to the gauze 10 when the grain drawer 8 is pushed in too much. The top of the gauze 10 at the front end of the frame is fixedly connected to the front frame 1, and the bottom end is fixedly connected to a pull rod 11, so that the gauze 10 at the front end is curtain-like, making it easy to put in and take out the grain drawer 8. At the same time, the columnar pull rod 11 plays a load-bearing role, so that the gauze 10 at the front end can be laid flat at the front end, preventing it from blowing up under the action of wind and allowing large-volume debris to enter. The space formed by the front groove 101 and the corresponding rear groove 201 is provided with a grain drawer 8 of the corresponding size to hold millet. A separating device is provided on the front frame 1 to separate the millet when the grain drawer 8 is put in.
[0017] The separating device includes several toothed rods 4 and separating teeth 5. The toothed rods 4 are spaced apart at the top of the front groove 101 and connected to the front frame 1. Several separating teeth 5 are spaced apart at the bottom of the toothed rods 4. The lowest point of the separating teeth 5 is no more than 5cm away from the bottom of the grain tray 8. The separating teeth 5 are made of rubber, which avoids obstructing the grain tray 8 when it is placed in.
[0018] To ensure sufficient ventilation between each layer of grain drawer 8, the vertical spacing of the front groove 101 is no less than 30cm.
[0019] To increase the contact between the millet at the bottom of the grain tray 8 and the air, the bottom of the grain tray 8 is made of mesh with a mesh count of less than 20, which prevents the millet from falling out.
[0020] The frame is square with the same length and width, and the grain tray 8 is also square. This makes it convenient to remove the grain tray 8 after the millet has been dried for a period of time, and put it back into the frame with the side of the grain tray 8 as the front end. During the process of putting it in, the separating teeth 5 are used to separate the millet again, so that the millet in the grain tray 8 is separated in a cross shape, which speeds up the drying process and makes the millet in the grain tray 8 dry more evenly, avoiding the situation of local incomplete drying.
[0021] The working process of this embodiment is as follows:
[0022] First, spread the millet evenly in the grain tray 8. Then, the operator picks up the pull rod 11 and places the pull rod 11 and the gauze 10 at the front of the frame on the top of the frame. Then, push the grain tray 8 into the frame along the front groove 101 until the front of the grain tray 8 hits the limiting plate 202. During the placement of the grain tray 8, the separating teeth 5 automatically separate the millet into a wave shape, increasing the contact area between the millet and the air in the grain tray 8. After the grain trays 8 are placed in order, lower the pull rod 11 so that it hangs naturally at the front of the frame, causing the gauze at the front of the frame to spread out and hang down. Then, push the frame to a place with good air circulation. In addition, multiple drying devices can be set up and placed at intervals according to the drying capacity requirements. After drying for a period of time, take out the grain tray 8 and put it into the frame again with the side of the grain tray 8 as the front. During the placement process, the separating teeth 5 are used to separate the millet again, so that the millet in the grain tray 8 is separated in a cross shape, making the millet in the grain tray 8 drier evenly.
