A dampening machine capable of improving the uniformity of temperature and humidity of tobacco leaves and reducing crushing

Abstract

The invention relates to a dampening machine capable of improving the uniformity of temperature increase and humidification of tobacco leaves and reducing crushing. By adding a hot air piping system, a moisture exhausting piping system and a circulating air piping system to the drum tobacco leaf dampening machine, a hot air outlet pipe is installed. There are fins and rakes, through the fins and staggered arrangement of rakes, the cigarettes can be loosened better, and the problem of insufficient loosening of the cigarettes at the exit of the roller blade moisture conditioner can be solved. The fin divides the falling distance of the material into two sections to reduce the impact force of the falling material. The cross flow of the hot air and the material is used to form an "air cushion" effect, which plays a buffer role in the falling of the material. Loosen and support the falling material to achieve the uniformity of material temperature increase and humidification, and improve the comprehensive quality and processing resistance of the smoke sheet as a whole.

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
