The invention discloses a threshing, re-drying and impurity removing device and an impurity removing method. The impurity removing device comprises a discharging gathering belt, an infrared spectrum detection mechanism and an air blowing mechanism. The discharging gathering belt comprises a first belt body and a second belt body, the conveying surface of the first belt body and the conveying surface of the second belt body are coplanar, and an impurity removing gap is formed between the tail end of the first belt body and the starting end of the second belt body. The infrared spectrum detection mechanism is set to be used for detecting infrared spectrum data of the materials on the first belt and / or infrared spectrum data of the materials passing through the impurity removing gap; the airblowing mechanism comprises at least one air blowing opening corresponding to the impurity removing gap. According to the threshing, re-drying and impurity removal device, the types of materials can be judged through the infrared spectrum detection mechanism, impurities are blown out of the impurity removing gap through the air blowing mechanism to be discharged out of the discharging gathering belt, the impurity removal efficiency is high, and the working efficiency of the threshing and re-drying process is not prone to affection.
Description
technical field [0001] The invention relates to the field of threshing and re-roasting, and more specifically, to a device and method for removing impurities from threshing and redrying. Background technique [0002] As the first workshop of cigarette production, threshing and redrying plays a vital role in the quality of tobacco leaf raw materials. With the development of refinement, scale and purification of cigarette production, tobacco companies pay more attention to the quality of tobacco leaf raw materials, especially the purity of tobacco leaf raw materials, which directly affects the use of cigarette formula and the stability of brands. [0003] The purity of tobacco leaves in the threshing and redrying process mainly refers to the impurities in the tobacco leaves and the stem content rate in the leaves. For the sundries in the tobacco leaves, the sundries are usually screened out by sieving. However, the impurity removal efficiency of the sieving and impurity remo...
