Low-flow speed steam nozzle for processing tobacco

Abstract

The invention discloses a low flow speed steam nozzle for tobacco processing, which comprises a steam pipeline (1), wherein the steam pipeline (1) is connected with a straight cylinder type nozzle (2) of which the diameter is multiple times larger than that of the steam pipeline (1); and the outer layer of an outlet of the straight cylinder type nozzle (2) is provided with a second level mesh choke plate (4), the inner layer thereof is provided with a first level mesh choke plate (3), the aperture of meshes on the first level mesh choke plate (3) is larger than that of the meshes on the second level mesh choke plate (4), and the number of the meshes on the second level mesh choke plate (4) is more than that of the meshes on the first level mesh choke plate (3). The low flow speed steam nozzle for tobacco processing can achieve loosening and dampening precision processing of tobacco flakes in a common loosening and dampening machine, can effectively improve the stability and evenness of the loosening and dampening precision processing of the tobacco flakes, and achieve the fine processing of tobacco leaves; besides, the low flow speed steam nozzle has the advantages of simple structure, convenient manufacture and reliable performance.

Description

technical field [0001] The invention relates to a tobacco processing device, in particular to a low-flow-rate steam nozzle for tobacco processing, which applies steam to the tobacco sheet accurately and uniformly during the process of loosening, rehydrating and feeding the tobacco sheet. Background technique [0002] Tobacco sheet loosening and remoisturization and filling treatment are indispensable links in the cigarette processing process. The treatment effect has a great impact on the sensory quality of cigarette products. The main reason is that the tobacco sheet passively absorbs the heat in the steam to change the chemical composition of tobacco. Improving the stability, uniformity and controllability of steam application is an urgent problem to be solved in the industry. The opportunity of passive heating of the smoke sheet material during the passage in the equipment is uneven. The original device has a part of the smoke sheet that is instantly blown to the discharg...

AI Technical Summary

Problems solved by technology

The opportunity of passive heating of the smoke sheet material during the passage in the equipment is uneven. The original device has a part of the smoke sheet that is instantly blown to the discharge end of the equipment during the processing process due to the excessive steam flow rate, and the radiation surface is small, causing the smoke sheet to accept Obstacles such as inconsistency of steam heat energy make it impossible to effectively control the change of tobacco chemical components during the heating process. At the same time, traditional processing has the problem of poor uniformity
