Efficient vertical type pneumatic separation equipment and application technology thereof

Abstract

The invention discloses efficient vertical type pneumatic separation equipment and an application technology thereof. Through double and three positive pressure pneumatic separation machines, the efficient vertical type air separation equipment has a simple structure, is liable to maintain and shortens the pneumatic separation process of materials, so that loss of the temperature and the moisture of the materials is reduced, and material breaking is lowered. Through adoption of the technology, the technological layout and flow of the traditional threshing and pneumatic separation equipment are changed, a matching mode of a threshing machine and a pneumatic separation machine can be flexibly designed, and threshing times of stem-containing leaves are reduced; and meanwhile, as feeding is uniform, the large and medium flake rates of discharged tobacco flakes are increased, and the availability of tobacco stems is improved. The equipment and the applied technology have the advantage of small technological transmission power, so that the energy consumption is greatly lowered, and the place utilization ratio is greatly optimized.

Description

technical field [0001] The invention relates to a high-efficiency vertical air separation equipment and its application process, in particular to the vertical threshing and air separation treatment equipment and process for tobacco leaves and tobacco stems, belonging to the technical field of leaf threshing and redrying process and equipment in the tobacco processing industry . Background technique [0002] At present, in the production and processing process of threshing and redrying generally adopted in China, the tobacco leaves are separated from the tobacco flakes and tobacco stems under the action of the leaf thresher, and the separated tobacco flakes and tobacco stems are transported to the air separator for tobacco flakes. wind sorting. [0003] The domestic production process of leaf threshing air separation is: after the mixture of tobacco sheets and tobacco stems after the first-level (four) leaf threshing machines is collected, five air separation machines connec...

AI Technical Summary

Problems solved by technology

Since such an air bin can only be used as a first-level sorting, it often requires at least two air bins in series for multi-level sorting, and then enters the next level of sorting. The number and number of bins are large, which has a direct impact on the moisture content and large piece rate of the material
