Description

Technical Field

[0001] The utility model relates to the technical field of wheat storage equipment, in particular to a wheat storage dryer. Background Art

[0002] Wheat is a general term for wheat plants. It is a monocotyledonous plant and a kind of gramineous plant widely planted all over the world. The caryopsis of wheat is one of the main foods of humans. After being ground into flour, it can be used to make foods such as bread, steamed buns, biscuits, and noodles. After fermentation, it can be made into beer, alcohol, liquor, or biofuel. Wheat is rich in starch, protein, fat, minerals, calcium, iron, thiamine, riboflavin, niacin, vitamin A, vitamin C, etc. Before wheat storage, it is necessary to dry it in time to remove the moisture in it. Traditional drying is affected by the weather, occupies a large amount of space, and requires a large amount of manpower and time to complete the drying work. The workload is huge and the work efficiency is low. Most factories use dryers to dry wheat. The existing dryers place wheat inside a drying box and blow hot air into the drying box for drying.

[0003] A dryer refers to a mechanical device that uses heat energy to reduce the moisture content of materials and is used for drying operations on objects. The dryer vaporizes and overflows the moisture in the materials by heating to obtain solid materials with a specified moisture content. The purpose of drying is for the use of materials or further processing needs.

[0004] Publication No. CN208817917U: A wheat dryer, including a base. The utility model can make each part of wheat evenly heated, timely release moisture, which helps to improve the drying efficiency, can filter and remove impurities in wheat, which helps to improve the quality of wheat, can achieve intermittent feeding, which helps to improve the phenomenon that wheat accumulation affects the filtering effect and drying efficiency, can make wheat enter the inside of the filtering cylinder for repeated drying, and can effectively ensure the drying effect.

[0005] This patent uses a stirring device to flip and disperse wheat and evenly dry each wheat. However, the moisture generated during the wheat drying process cannot be timely discharged and will accumulate in the drying box, thus affecting the drying effect of wheat. At the same time, in order to completely dry the wheat, this patent will repeatedly dry the wheat. Since the humidity of each batch of wheat is different, the drying time of each batch of wheat is different. Because there is no humidity detection device for the humidity generated during drying in this patent, it is impossible to intelligently adjust the wheat drying time. Moreover, the temperature of the wheat after drying is relatively high and needs to be placed for a period of time to cool down before it can be stored at the storage temperature. Therefore, a wheat storage dryer that can monitor the wheat humidity in real time during the wheat drying process and can directly store the wheat after drying is needed. Content of the Utility Model

[0006] In view of the above, after the existing wheat drying is completed, it needs to cool naturally before it can be put into the warehouse for storage. At the same time, the wheat drying needs to be repeatedly lifted to the top of the drying equipment, which greatly reduces the problem of heat concentration during wheat drying. The present utility model is proposed.

[0007] Therefore, the purpose of the present utility model is to provide a wheat storage dryer, and its purpose is to improve the existing wheat dryer that has no rapid cooling function, is prone to accumulate high-temperature moisture during the drying process, and needs to repeatedly lift the wheat to the top of the drying equipment during the drying process to fully dry.

The right end of the rotating shaft penetrates through the drying tank and extends into the interior of the drying tank. The right end of the rotating shaft is fixedly connected with the left end of the main pipe.

[0012] As a preferred scheme of the wheat storage dryer of the present utility model, wherein: the rotary drying mechanism further includes a stirring component arranged on the outer surface of the main pipe.

[0044] Embodiment 2

[0045] Refer to Figures 2-4 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the angle adjustment mechanism 3 includes a first fixed frame 31 and a second fixed frame 32. The inner surface of the first fixed frame 31 is rotatably installed with a hydraulic rod 33 through a rotating rod, and the inner surface of the second fixed frame 32 is rotatably installed with a hydraulic cylinder 34 through a rotating rod. The output end of the hydraulic cylinder 34 is fixedly connected to the outer surface of the hydraulic rod 33 through a piston. The bottom of the second fixed frame 32 is fixedly connected to the ground. The hydraulic cylinder 34 can rotate within the second fixed frame 32, and the hydraulic rod 33 can rotate on the first fixed frame 31. The first fixed frame 31 is fixed to the bottom of the drying tank 1. At the same time, there is a matching drying tank 1 fixer at the other end of the drying tank 1, so that during the use of the angle adjustment mechanism 3, one end of the drying tank 1 can be lifted.

[0048] During use, wheat will be discharged into the drying tank 1 through the feeding pipe 5. The moisture generated during the drying process of the wheat will be discharged through the discharge pipe 41. During the discharge process, the moisture detector 42 will detect the content of water molecules in the gas, thereby controlling the start and stop of the heater 216. During the stirring process, the hydraulic cylinder 34 and the hydraulic rod 33 can be controlled. The hydraulic cylinder 34 drives the first fixing frame 31 to move up and down through the hydraulic rod 33. The first fixing frame 31 drives one end of the drying tank 1 to move up and down, adjusting the inclination angle inside the drying tank 1 to control the flow of wheat in the drying tank 1, so that the wheat can be evenly dried and stirred by the stirring rod 232.
