Rotary vacuum loosening and dampening machine and its loosening and dampening method

Abstract

The invention relates to a rotary-type vacuum loose moisture regain machine and a loose moisture regain method thereof. The moisture regain machine comprises an incoming material conveying device, an outgoing material conveying device, a loose moisture regain barrel, a barrel body driving device, a humidifying device, a vacuum device, a rotary sealing device and a control device, a barrel body is connected with the barrel body driving device through a power transmission mechanism, the power transmission mechanism, of the barrel body driving device, arranged on the barrel body is connected with a power machine output shaft of the driving device, rotary sealing units communicated with an inner cavity of the barrel body are arranged at two ends of the barrel body, at least one sealing door for feeding and discharging is arranged on the barrel body, and a door frame is arranged around each sealing door. By the rotary-type vacuum loose moisture regain machine and the loose moisture regain method thereof, equipment and a process material thereof are in a rolling state during moisture regain, tobacco leaf moisture regain qualification rate is increased, a humidifying medium is ensured to be fully sprayed on the material, humidifying and loosening quality is improved, and the material is in a vacuum environment in the whole process, so that material return penetration rate is increased.

Description

technical field [0001] The invention relates to a low-temperature vacuum humidifying and loosening equipment and its technology, in particular to a rotary vacuum loosening and dampening machine and a loosening and dampening method thereof. Background technique [0002] In the existing humidification technology, the effect of the vacuum resurfacing device is better, but at present, the material in this vacuum resurfacing process is in a static state. Because the material is compacted and stored for a long time, the surface and interior of the material often appear after rehydration. The degree of moisture regain of the material is uneven, and the amount of moisture added cannot be in place at one time, and the temperature of the moisture addition process is relatively high. In order to meet the process requirements, it is necessary to add moisture and loosen again through other forms of moisture addition devices, which increases the Increased equipment investment and operatin...

AI Technical Summary

Problems solved by technology

However, under this condition, the loosening effect and the moisture regain rate are poor, and the loosening rate of the smoke sheet is mostly between 80% and 90%, which cannot complete the task of loosening and regaining moisture very well.

[0005] 2. In the process of loosening and regaining moisture, the smoke sheet is heated unevenly

Tobacco raw materials are pressed into fast boxes for storage and transportation after rebaking, and the bulk materials enter the loosening drum, and a small part of the tobacco leaves in the center of the material cannot be effectively dispersed. This part of the tobacco leaves cannot be heated evenly during the loosening process, and the steam The change of the flow rate is the uneven heating of the dispersed smoke sheet

[0006] 3. The current loose moisture regain equipment has a high breakage rate

When the cigarette block enters the drum-type tobacco leaf moistening machine, it is difficult for the blocky material to regain moisture in a short time. Due to the rotation of the drum, the rake nails and the frying plate in the drum will lift the cigarette block in a spiral, and keep turning it over like this, resulting in tobacco leaves Larger crushing, so the traditional loose moisture regaining method has a high tobacco leaf crushing rate in the drum-type tobacco leaf moisture conditioning machine
