Tobacco shred screening and shortening equipment

Abstract

The invention discloses novel tobacco shred screening and shortening equipment which belongs to the technical field of mechanical equipment. The novel tobacco shred screening and shortening equipment comprises an air material separation box and a blanking box body, wherein the air material separation box and the blanking box body are fixedly connected; a winnowing impurity removal box is fixedly connected to the lower part of the blanking box body; and a discharge air lock is arranged on the lower part of the blanking box body, and the blanking box body is fixed on a bracket. The novel tobacco shred screening and shortening equipment also comprises a tobacco shred poking device, an electromotor and a baffle plate, wherein the electromotor is arranged on a side part of the blanking box body; the tobacco shred poking device is arranged in the blanking box body; the electromotor and the tobacco shred poking device are connected in a transmission mode; the tobacco shred poking device consists of a cut-off device and a plurality of loosing devices; the cut-off device is arranged sideward above the loosing devices, and the plurality of loosing devices are simultaneously rotated; the rotation speed of the various loosing devices are different, and the cut-off device is reversely rotated; and the baffle plate is arranged on a side part of the cut-off device. The novel tobacco shred screening and shortening equipment has the advantages that tobacco shred rolls can be more easily loosed, and meanwhile, long tobacco shreds can be cut off so as to improve the uniformity of the tobacco shreds and the efficiency of winnowing impurity removal.

Description

Technical field [0001] The invention relates to a shredded tobacco processing equipment, in particular to a shredded tobacco screening and shortening equipment, belonging to the technical field of mechanical equipment. Background technique [0002] Roasting is an indispensable process in the cigarette process, and the moisture of the leaves after cutting is generally about 18%. It is necessary to dry and dehumidify, remove excess moisture, and make the moisture of the cut tobacco uniform to meet the requirements of the cigarette process. After cutting, the leaf shreds will stick to each other. After the silk is dried, the tobacco can be fully loosened, and a certain degree of curling can be produced, which increases the filling capacity of the tobacco. In addition, during the silk drying process, as the moisture of the cut tobacco evaporates, part of the impurities and volatile nicotine can be eliminated, and the smoking quality of the cut tobacco can be improved. After drying,...

Problems solved by technology

[0003] However, no matter whether you use a drum dryer or air-flow drying equipment, because there are many filaments in the shredded tobacco, they will be entangled with each other during the drying process to form silk clusters, resulting in local uneven temperature and moisture, and the drying equipment will also be affected by temperature. Higher burnt tobacco shreds need to be removed

Existing winnowing equipment cannot loosen the filament clusters very well, shorten the filaments, make the shredded tobacco uneven, and it is difficult to remove coke flakes, stem sticks and other sundries in the shredded tobacco, and consumes a lot of energy at the same time
