A method and device for improving the moisture uniformity of tobacco leaves at the outlet of a burley tobacco curing machine

Abstract

The invention discloses a method and a device capable of improving outlet tobacco moisture uniformity of a burley tobacco parching machine. The device comprises a water tube and a steam tube which are parallel, wherein a guide tube is crossly spanned on the water tube and the steam tube at a certain distance, and a spray nozzle is arranged on the cross guide tube; the spray nozzle is an adjustable spray nozzle. The method comprises the following steps: estimating humidifying capacity of a moisture regaining region of the parching machine; estimating parameters of the spray nozzle on the original installation position of the moisture regaining region of the parching machine, wherein the parameters include a spraying angle and a spraying distance; re-selecting a moisture regaining spray nozzle according to the data. The parching machine is re-designed and re-selected on the spray nozzle of the moisture regaining region; the used spray nozzle is adjustable, so that the atomizing effect of the spray nozzle can be regulated, the atomizing effect of the spray nozzle on the same pipeline is consistent, the stable uniformity of the outlet tobacco moisture uniformity of the burley tobacco parching machine is improved. Meanwhile, the spray nozzle cleaning period is effectively prolonged, and equipment production efficiency is improved.

Description

technical field [0001] The invention relates to a method and a device for improving the moisture uniformity of tobacco leaves at the outlet of a burley tobacco curing machine. Background technique [0002] The working principle of the burley tobacco roasting machine equipment in the silk workshop is that the burley tobacco slices processed to 34% moisture will be heated by the hot air in the roasting machine after entering the roasting machine and traveling with the grilling machine mesh belt Drying and removal of ammonia therein; then, the dried leaves are cooled down in the cooling zone and adjusted to about 16% moisture in the rewetting zone by atomizing airflow. [0003] The nozzles in the moisture resurgence area of ​​the Burley tobacco roasting machine can be sprayed downwards or upwards. The structural diagram of the existing nozzles in the moisture recovery area of ​​the Burley tobacco roasting machine is shown in the following figure: figure 1 As shown, this nozzle...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to solve the above problems, to provide a method and device for improving the moisture uniformity of the tobacco leaves at the outlet of the Burley tobacco curing machine, and to solve the problem of the change of the atomization state of the five nozzles on the series pipeline due to the fluctuation of the pressure of the fluid medium. Adjust the five nozzles so that the atomization effect is consistent, so that the moisture on the tobacco leaves passing through the moisture resurgence zone is even
