[0002] Flour is a powder made from wheat. According to the protein content in the flour, it can be divided into high-gluten flour, medium-gluten flour, low-gluten flour and gluten-free flour. Flour is the staple food in most parts of northern China. There are many kinds of food made from flour, with various styles and different flavors. Generally, flour is ground from wheat during production. Wheat needs to be cleaned and dried before grinding. Wheat containing a lot of water cannot meet the requirements of grinding, so it needs to be dried by a drying device.

[0003] For example, a high-gluten wheat flour drying and processing equipment disclosed in a Chinese patent with the publication number CN219995750U belongs to the technical field of drying and processing equipment, and includes a base, a top shell is fixedly connected to the top of the base, bearings are arranged on the opposite inner walls of the top shell, and a rotating shaft is penetrated inside the two bearings. Its beneficial effect is that by setting a first motor, a heating wire, a blower and an elastic guide plate, the first motor drives the rotating shaft to rotate, so that the rotating shaft drives the screen drum to rotate, so that the screen drum continuously turns the wheat through the spiral plate, and the heating wire heats the air inside the drying shell, so that the blower inputs the hot air into the top shell through the ventilation duct, so as to facilitate the rapid drying of the wheat in the screen drum, and at the same time, the screen drum is convenient for sieving out impurities in the wheat to ensure the purity of the wheat flour, so that the impurities fall onto the elastic guide plate, and the elastic guide plate is driven to vibrate by the vibration motor, so as to facilitate the collection of impurities on the elastic guide plate into the inside of the collection shell;

[0004] Some problems were found during the use of the above-mentioned existing high-gluten wheat flour drying and processing equipment. First, after the wheat was added into the screening cylinder, the wheat was evenly distributed in the screening cylinder, and it was difficult to be discharged from the narrow inlet and outlet later. Secondly, the impurities contained in the wheat, such as wheat bran shells, which are relatively light, will enter the drying shell with the hot air, and it is very easy to catch fire after contacting the heating wire, causing a fire.

[0023] In this embodiment, the wheat raw material is delivered from one end of the conveying cylinder 5 to the interior thereof, and then the conveying cylinder 5 is rotated. The auger blades 502 will drive the wheat raw material to move inside the conveying cylinder 5, and finally transport it away from the other side. The internal exhaust device of the blower head 3 is started, and the air can be delivered to the inside of the blower head 3 through the air duct 301. The blower head 3 fits the conveying cylinder 5 to avoid, and then the air will be delivered to the inside of the conveying cylinder 5 through the sieve hole 501. The heating wire 302 will heat the passing air, so that the hot air will dry the wheat raw material. At the same time, the first filter 204 and the second filter 303 will prevent the impurities in the wheat from entering the inside of the blower head 3 with the hot air, thereby effectively avoiding the problem of contact between the heating wire 302 and the impurities in the wheat raw material and causing a fire.

[0024] Among them, in order to achieve the purpose of air circulation, the present device is implemented by adopting the following technical solutions: an installation groove 101 is opened on the front of the dryer shell 1 and located below the fan shell 2, and a collection box 102 is slidably installed in the installation groove 101, a discharge inclined plate 103 is fixedly connected to one side of the dryer shell 1, and a steam exhaust port 104 is fixedly connected to the top of the dryer shell 1, and the steam exhaust port 104 is located below the air guide 301. An exhaust motor 201 is fixedly connected to the fan shell 2 through a mounting frame, and a transmission shaft 202 is fixedly connected to the output end of the exhaust motor 201, and an exhaust blade 203 is fixedly connected to the transmission shaft 202. The transmission shaft 202 passes through the first filter screen 204, and a brush 205 is fixedly connected to the end of the transmission shaft 202, and the brush 205 cooperates with the first filter screen 204.

[0025] The collecting box 102 can receive the sieved impurities, which is convenient for collecting the sieved impurities. The discharging inclined plate 103 is used to collect the discharged wheat raw materials. The steam outlet 104 is located above the dryer shell 1. The water vapor evaporated in the wheat raw materials will be discharged upward through the steam outlet 104. At the same time, since the air duct 301 is located above the steam outlet 104, the discharged water vapor will contact the air duct 301, heat the air duct 301, and thus preliminarily heat the circulating air, saving a certain amount of energy and starting. The exhaust motor 201 can drive the transmission shaft 202 to rotate. The rotation of the transmission shaft 202 will synchronously drive the exhaust blades 203 and the brush 205 to rotate. The rotation of the exhaust blades 203 will draw air into the air duct 301 and then discharge it from the blower head 3, so that a stable air duct is formed inside the dryer shell 1. The brush 205 cooperates with the first filter 204. The rotation of the brush 205 will scrape off impurities adsorbed on the surface of the first filter 204 to avoid the accumulation of impurities on the first filter 204, which will cause the problem that air cannot be inhaled.

[0026] Among them, in order to achieve the purpose of breaking up the wheat raw materials in a cohesive state, the present device adopts the following technical solutions: a power motor 403 is fixedly connected to a side bracket 105, the output end of the power motor 403 is fixedly connected to the support shaft 4, a number of connecting support rods 402 are fixedly connected to the support shaft 4, a number of sieve holes 501 are opened in the conveying cylinder 5, and a flip plate 503 is fixedly connected to the inner wall of the conveying cylinder 5.

[0027] The power motor 403 can drive the support shaft 4 to rotate, and the rotation of the support shaft 4 will drive the conveying cylinder 5 to rotate. The rotation of the conveying cylinder 5 will drive the flip plate 503 to rotate. The flip plate 503 is tilted so that the rotation of the flip plate 503 will lift the internal wheat raw materials to the highest point and slide down, so that the wheat raw materials will contact with the connecting support rod 402 on the support shaft 4. The connecting support rod 402 will break up the wheat raw materials in a cohesive state, thereby avoiding the problem that the inside of the cohesive wheat raw materials cannot be effectively dried.

[0028] The working principle and use process of the utility model are as follows: when using, the device needs to be placed in a suitable position, and the wheat raw materials are delivered from one end of the conveying cylinder 5 to the inside thereof, and the power motor 403 is started to drive the conveying cylinder 5 to rotate.
