Moisture regain machine capable of improving warming and humidifying uniformity of tobacco leaves and reducing breakage

Abstract

The invention relates to a moisture regain machine capable of improving the warming and humidifying uniformity of tobacco leaves and reducing breakage. A hot air pipeline system, a moisture removal pipeline system and a circulating air pipeline system are additionally arranged in the roller tobacco leaf moisture regain machine, a hot air outlet pipeline is provided with fins and rake nails, and through the fins and the rake nails arranged in a staggered mode, tobacco blocks can be better loosened, and the problem that the tobacco blocks which are not fully loosened still exist at an outlet of the roller type tobacco leaf moisture regain machine is solved. The material falling distance is divided into two segments through the fins of the hot air pipeline, and the material falling impact force is decreased; the 'air cushion' effect is formed through cross flowing of hot air and the materials, and the buffering effect on material falling is achieved; the falling materials are loosened and supported through conical shoveling nails arranged on the pipelines, and the purpose of improving the warming and humidifying uniformity of the materials is achieved, and the comprehensive quality and processing resistance of the tobacco leaves are integrally improved.

Description

technical field [0001] The invention relates to the field of tobacco processing, in particular to a dampening machine capable of improving the uniformity of temperature and humidification of tobacco leaves and reducing crushing. Background technique [0002] The drum-type blade dampening machine is the key process equipment for tobacco thread making. The principle is that the tobacco leaves are loosened during the turning and conveying process in the drum. The inner wall of the drum is equipped with rake nails. The main function is to fully loosen the tobacco block. The rake nails on the inner wall of the drum are used to guide and loosen the blades. There is an insulation layer outside the drum to reduce the loss of heat in the drum. The blades are sent into the drum of the drum blade dampening machine by a vibrating conveyor, and the drum is driven by a transmission device to rotate. , the blade rolls forward under the action of the axial inclination of the drum and the gu...

AI Technical Summary

Problems solved by technology

[0003] During actual use, the following deficiencies were found: First, the flow rate of the incoming tobacco material was relatively continuous and stable, but in the process of throwing and falling in the cylinder, because the lifting board and the nailing were arranged at intervals, the material throwing process was discontinuous, which easily caused Tobacco leaves are heated unevenly

Second, due to the thick material layer of the tobacco leaves, some of the tobacco leaves are trapped in the middle and cannot be fully heated

Third, the moisture content of the incoming tobacco leaves is relatively small. After the tobacco leaves are thrown up, due to the long falling distance, the hard contact between the tobacco leaves and the tube wall will easily cause the tobacco leaves to be broken.

Fourth, in the actual production and operation process, there are still insufficient loose cigarettes at the outlet of the existing tubular blade moisture conditioner

The drum-type blade dampening machine cannot fully loosen the cigarettes. According to the analysis, because the specific gravity of the cigarettes is larger than that of the tobacco leaves, the falling speed of the cigarettes after being picked up is faster than that of the tobacco leaves. Poor moisture content uniformity
