Embodiment Construction

[0031] The present invention will further describe leaf silk feeding process and equipment below in conjunction with accompanying drawing:

[0032] Such as figure 1 Shown: the shredded leaf feeding process of the present invention comprises four operations such as shredding, warming and humidification loosening, winnowing loosening and feeding, and the concrete steps of each operation are as follows:

[0033] 1. Shred: Send the raw tobacco sheet (moisture content 18.0% to 19.0% ± 1.0%) into the shredder for shredding. Low knife door pressure shredding machine (knife door pressure is 0.12-0.15MPa) for shredded, shredded width of 1.0±0.1mm.

[0034] 2. Warming and humidification loosening: In order to loosen the shredded leaves, pass the shredded leaf shreds through a quantitative feeder (the flow fluctuation of the quantitative feeder is less than 1.0%, and the electronic scale in the quantitative feeder measures Accuracy is less than 1.0%) transported to the vibrating fluidi...

Abstract

The invention relates to a leaf thread material feeding process and equipment, which belong to the technical field of tobacco processing. The invention is characterized in that the leaf thread feeding process sequentially comprises the working procedures of thread cutting, temperature increasing and humidifying loosening, air separation loosening and material feeding. The equipment applicable to the process comprises a thread cutting machine, a quantitative material feeding machine, a vibration vulcanization bed, an air separation loosening device and a vertical material feeding machine whichare sequentially ranged, wherein each equipment is connected through material conveying mechanisms, the vertical material feeding machine comprises a material feeding cavity, a material inlet airlockand a material outlet airlock are respectively arranged on the top and the bottom of the material feeding cavity, a material scattering mechanism is fixed on the upper part of the material feeding cavity, a material liquid atomizing system is communicated with the material feeding cavity through an air inlet pipe and a air return pipe of a hot air circulation system, and a sealed cyclic feeding system is formed. The process and the equipment can solve the problems of large thread cutting pulverization products of low-water-content tobacco flakes and material feeding aggregation of tobacco threads, the material liquid atomizing effect is good, the material liquid absorption velocity by the tobacco threads is high, the material feeding uniformity and the effectiveness are improved, in addition, the material storing time after the material feeding is shortened, and the production efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a shredded leaf feeding process and equipment. Background technique [0002] Feeding is one of the key processes in the silk-making process. Feeding is directly related to the sensory quality of cigarette products, the physical quality and chemical composition changes of in-process products during processing. Defects of tobacco leaves and the improvement of the effective utilization rate of feed liquid and the production efficiency of shredded silk have a direct impact. [0003] The existing feeding process generally adopts the screening and feeding of loose leaves after moisture resurgence, and the feeding equipment is a drum-type leaf feeding machine (see "Cigarette Technology Specification", page 14 and Appendix F). This process and equipment exist The following problems: First, the feeding accuracy is poor, because the blades are prone to "bridge and o...
