High-efficiency energy-saving threshing air separation new process and equipment

Abstract

The invention relates to a high-efficiency energy-saving threshing air separation new process and equipment, and particularly relates to a threshing redrying process which carries out air separation on tobacco flakes and tobacco stalks and belongs to a tobacco processing industry and the technical field of equipment. The threshing redrying process sequentially comprises the following steps of: a scraping plate feeding machine, a bin type feeding machine, a proportional distributor, a first-level threshing machine set, a conveying belt, a first-level air separation machine set (double-bin air separator), a stalky leaf conveying belt, a second-level threshing machine set, the conveying belt, a second-level air separation machine set (three-bin air separator), the stalky leaf conveying belt, a third-level threshing machine set, the conveying belt, a third-level air separation machine set (three-bin air separator), the stalky leaf conveying belt, a fourth-level threshing machine set, the conveying belt and a fourth-level air separation machine set (three-bin air separator), wherein the first-level air separation machine set is provided with an air pressure type double-bin air separator which only separates qualified tobacco flakes; and the second-level air separation machine set, the third-level air separation machine set and the fourth-level air separation machine set are provided with air pressure type three-bin air separators which can separate qualified tobacco flakes and tobacco stalks.

Description

Technical field [0001] The present invention involves a new process and equipment for high -efficiency energy -saving and beating leaves.Specifically, the wind sorting of tobacco slices and smoke stalks, which belongs to the leaf compound roasting process and equipment technology field of the tobacco processing industry. Background technique [0002] The chump wind division of the bearing leaves of the beating leaves has the characteristics of classification of leaf and multiple wind divisions. The tobacco leaves are separated by the tears of the chopping machine and the tobacco stalks., Tobacco stalk mixture was transported to the wind split machine for cigarette films. [0003] At present, the domestic production process in China is: After the cigarette slices and cigarette stem mixtures are summarized by the first level (four) leaf machine, the five winds and slices are connected in series to the fifty wind scores.If the ingredients are not separated from the tobacco leaves th...

Problems solved by technology

[0004] In this process, the temperature of the tobacco leaves drops greatly and the moisture loss is large during the process of wind conveying and winnowing, which leads to a decrease in the large and medium slice rate of the tobacco sheet, and an increase in the dryness rate. The material is discharged only after the air separation machine, which reduces the availability of tobacco stems

Moreover, the pipe span of the air delivery device is large, the energy consumption of the fan is high, the noise is large, the transportation stability is poor, and the phenomenon of material blocking is easy to occur
