Drying and screening integrated production line

Abstract

The invention belongs to the technical field of automated production and provides a drying and screening integrated production line. The drying and screening integrated production line comprises a feeding mechanism, a first dryer, a hot-blast stove, a second dryer, a material conveying machine and a material screening machine. The feeding mechanism and a feeding port of the first dryer are arranged in a corresponding manner. A temperature sensor is arranged in the first dryer. The hot-blast stove communicates with the first dryer through a hot air pipe. Additionally, the hot air pipe is equipped with an electromagnetic valve electrically connected with the temperature sensor. The downstream of the first dryer is provided with a second dryer. A feeding end of the second dryer and a discharge port of the first dryer are arranged in a corresponding manner. The downstream of the second dryer is provided with the material conveying machine. A feeding end of the material conveying machine and a discharge end of the material conveying machine are arranged in a corresponding manner. Integral automated processing such as material drying, conveying and screening is achieved. Therefore, processing efficiency and processing quality of material are increased.

Description

technical field [0001] The invention relates to the technical field of automatic production, in particular to an integrated drying and screening production line. Background technique [0002] An automated production line generally refers to a production system that can automatically complete all or part of the manufacturing process of a product. It can effectively replace manual labor, and has the advantages of high efficiency and high quality. It is the development direction of modern industries; at present, automated production is widely used In the integrated processing of drying and screening of materials, such as the processing and production of Chinese herbal medicines and daily-use ingredients; in the process of processing Chinese herbal medicines, it usually involves drying the raw materials of the medicinal materials, which is for long-term preservation. Drying of Chinese herbal medicines is the process of dehydrating Chinese herbal medicines and maintaining their o...

Problems solved by technology

[0004] However, the inventors have found in practice that the drying equipment in the prior art is difficult to achieve precise regulation of the drying temperature, and cannot achieve uniform drying of materials. It is difficult to ensure the drying of materials while realizing the drying of materials The taste, nutritional elements or medicinal properties will not be destroyed. The drying efficiency and drying quality still need to be further improved, and most of them do not have the functions of automatic feeding filler and automatic discharging. When feeding, it is necessary to manually transport the Chinese medicinal materials to the In the drying equipment, manual auxiliary discharge operation is still required when discharging materials, which is labor-intensive, low-efficiency, and time-consuming, which greatly reduces the drying and processing efficiency of materials. At the same time, for traditional Chinese medicinal materials or Materials such as wakame, after the drying process, often appear to be entangled into agglomerates. Most of the existing material conveying equipment only has the function of conveying, which cannot effectively handle the agglomerated materials. The dried materials are directly When transported to the screening equipment for screening, the entangled materials are difficult to screen, which will affect the subsequent screening work, thereby affecting the screening efficiency and screening quality of the materials. In addition, the existing material screening equipment has a complex structure. , and it is impossible to realize the classification and screening of materials, the screening efficiency is low, and the screening effect still needs to be further improved. After the materials are screened, it is not convenient to sort and collect
