Technical Field
[0001] The utility model relates to the technical field of flour, in particular to a drying device for flour processing. Background Art
[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. Wheat flour is divided into special flour (such as bread flour, dumpling flour, biscuit flour, etc.), general flour (such as standard flour, enriched flour), and nutritionally fortified flour (such as calcium-enriched flour, iron-enriched flour, "7+1" nutritionally fortified flour, etc.) according to its performance and use; it is divided into special first-class flour, special second-class flour, standard flour, ordinary flour, etc. according to its precision; it is divided into high-gluten flour, medium-gluten flour and low-gluten flour according to the strength of the gluten.
[0003] In the process of flour processing, wheat needs to be pretreated, among which drying is particularly important. Drying refers to the process of removing solvents and retaining solid content in some way. It usually refers to the process of introducing hot air to evaporate and take away the moisture in the material. The degree of drying determines the quality of the flour. For example, a drying device for flour processing disclosed in Chinese patent application No. 202022479331.1. The utility model relates to the technical field of flour processing and discloses a drying device for flour processing, including a body, a feed pipe is fixedly connected to the top of the body, a stirring mechanism is fixedly installed on the inner top wall of the body, a sieve plate movably connected to the inner wall of the body is provided at the bottom of the stirring mechanism, and a block fixedly connected to the inner wall of the body is provided at the bottom of the sieve plate. The flour processing drying device achieves the purpose of high drying efficiency of the flour processing drying device, solves the problem of low drying efficiency of the general flour processing drying device, prevents the accumulation of wheat, and causes the situation that the surface wheat is dried first and then the wheat in the center is slowly dried. During the stirring process, impurities with a relatively large internal volume can fall to the bottom of the machine body through the sieve holes, reducing their space occupation and heat absorption, improving the work efficiency of the drying work, thereby improving the productivity of users, and meeting the use needs of users.
[0004] Although the above patent solves the problem of low drying efficiency of general flour processing drying devices, reduces its space occupancy and heat absorption, improves the efficiency of drying work, and thus improves the productivity of users, but in actual use, since the stirring blade area in the patent is small and there is a large gap between the stirring blade and the machine body, and the blowing angle of the fan is from left to right, the wheat is easily accumulated on the right side of the top of the sieve plate, which reduces the drying efficiency of the accumulated wheat. At the same time, the heating plate of the device is located inside the machine body, which makes it easy for the wheat to come into direct contact with it, causing part of the wheat to burn due to continuous heating, creating a safety hazard.
[0005] Therefore, it is necessary to modify the flour processing drying device in the above patent to effectively prevent the large gap between the stirring blade and the machine body from causing wheat accumulation, reducing the drying efficiency and effect of the wheat, and preventing the wheat from directly contacting the heating plate.
