Tobacco leaf moisture regaining and water adding control device and method

Abstract

The invention relates to a tobacco leaf moisture regaining and water adding control device and method, and belongs to the technical field of tobacco leaf moisture regaining processes. The device mainly comprises a water inlet valve, a blow-down valve, an electromagnetic valve, a water inlet pressure regulator, a first pressure detector, a second pressure detector, a plunger pump, an automatic pressure release valve, a sewage collection box, an atomization nozzle, a water inlet pipe, a water outlet pipe and a pressure controller. The water inlet pipe and the water outlet pipe are installed on the sewage collection box and connected to an inlet and an outlet of the plunger pump respectively, and the water inlet valve, the blow-down valve, the electromagnetic valve, the water inlet pressure regulator and the first pressure detector are sequentially arranged on the water inlet pipe; and the second pressure detector and an automatic pressure release valve are sequentially arranged on the water outlet pipe, and the atomizing nozzle is arranged at the tail end of the water outlet pipe. The water supply pressure is stable, the water adding atomization amount is kept consistent, the control precision is high, the tobacco leaf moisture regaining effect and the tobacco shred making quality are guaranteed, and the uniformity of the moisture content after tobacco leaves are loosened and regained is improved; and the equipment maintenance period is prolonged and the moisture regain treatment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of tobacco leaf moisture regain equipment, in particular to a tobacco leaf moisture regain control device and method. Background technique [0002] In the tobacco industry, threshing and redrying is the basic process of tobacco leaf processing. Among them, before the tobacco leaves enter the packaging box, in order to improve the storage and aging effect of the tobacco leaves, it is necessary to control and adjust the moisture content of the tobacco leaves. process. [0003] In the prior art, the water supply pressure is low during moisture regain treatment, the diameter of atomized water droplets is large, and the water pressure is unstable, and the amount of water atomized by adding water is inconsistent, which seriously affects the moisture regain effect and the quality of shredded (tobacco leaves). Improving the uniformity of the moisture content of loose tobacco sheets after moisture resurgence is cruc...

Problems solved by technology

[0003] In the prior art, the water supply pressure is low during moisture regain treatment, the diameter of atomized water droplets is large, and the water pressure is unstable, and the amount of water atomized by adding water is inconsistent, which seriously affects the moisture regain effect and the quality of shredded (tobacco leaves)

Improving the uniformity of the moisture content of the loose tobacco sheets after moisture resurgence is crucial to the control of process quality stability. The existing equipment has frequent failures in the moisture resurgence and water adding system during work, frequent equipment maintenance, and the moisture resurgence treatment efficiency is not ideal.
