Humidifying and dampening method for tobacco processing

Abstract

The invention relates to a humidifying and dampening method for tobacco processing. The tobacco processing humidifying and moisture regaining method comprises the following steps that tobacco baking is conducted, wherein a high-pressure micro-mist humidifying and dampening machine is arranged in front of a draught fan at an air inlet of a tobacco baking machine, the high-pressure micro-mist humidifying and dampening machine is started when tobacco curing is finished and the tobacco temperature is reduced to 40-60 DEG C, the draught fan works, and the spraying amount of the high-pressure micro-mist humidifying and dampening machine reaches 40-60 L so that the moisture regain in the tobacco baking machine can be kept 10-12%; and (2) sorting is conducted, specifically, an ultrasonic industrial humidifying and dampening machine is arranged at a sorting storehouse, the ultrasonic industrial humidifying and dampening machine adopts electronic overclocking oscillation to atomize water into water particles of 1-10 microns, and the water particles are introduced into the sorting storehouse through a pipeline; (3) recycling and storing are conducted, specifically, a humidifier water tank isarranged at the smoke station, the humidifier water tank supplies water to a high-pressure water pump, and the water pressure is increased to 4-7 Mpa through the high-pressure water pump. The moistureregaining speed is high; tobacco blackening caused by excessive humidification is not easily caused; the water content of tobacco leaves is increased and reaches the national standard.

Description

technical field [0001] The invention relates to the field of humidification, in particular to a method for humidifying and restoring moisture in tobacco processing. Background technique [0002] According to the "National Standards for Flue-cured Tobacco", the appropriate moisture content in the grading process of tobacco leaves is 16%-18%, that is, the tobacco leaves have a certain oily feeling, are not dry, the tendons are slightly soft and not easy to break, and the leaves are slightly soft when held. The leaves are not fragile, and the tobacco leaves that meet this requirement can highlight and enhance the identity of the tobacco leaves themselves during grading, meeting industrial needs. [0003] Tobacco humidification and rehydration is the process of regaining moisture in freshly cured tobacco through methods such as artificial rehydration and natural rehydration. The dryness and wetness of the water during the moisture resurfacing process will greatly affect the qua...

AI Technical Summary

Problems solved by technology

This method of moisture recovery is inefficient and the moisture recovery cycle generally takes 24 hours to get out of the kang, and it may take longer to regain moisture in the dry season of autumn; it is not conducive to improving the use efficiency of the tobacco kang and the problems of long sales cycle of tobacco leaves; There is a general technology to regain moisture through steam humidifiers, but due to the high humidity requirements, portable transportation and high power problems, the moisture regain rate of small (28L / H) equipment of this type is not enough, and the transportation of larger equipment (56L) is large. It is not conducive to activities, the power is also large, and it is inconvenient to move; the general high-pressure moisture resurgence equipment is poorly matched with the water treatment system, which leads to blockage of the nozzle, and the particles of the high-pressure equipment are relatively large, the tobacco room is relatively airtight, and the mist is not easy to spread and absorb
