Description

Rotary type vacuum loosening steam conditioner and remoistening process thereof
Technical field
The present invention relates to a kind of cryogenic vacuum and add damp loose equipment and technique thereof, particularly relate to a kind of rotary type vacuum loosening steam conditioner and remoistening process thereof.
Background technology
Existing, add in damp technology; vacuum humidifying device effect is better; but in current this vacuum conditioning technique, its material remains static; because material is through overcompaction and through long-term storage; through getting damp again by often there will be the moisture regain degree of material top layer and materials inside uneven; and adding tidewater component can not one-time-reach-place; and its to add damp process temperature higher; for reaching technological requirement, also need through other forms of equipment for damping, to add again tide and loose again; so just strengthened equipment investment and operating cost, and effect neither be best.
Lamina bale before moisture regain is carried out to one of loose formula tobacco productive corporation main technique link in fiber tow production process.Lamina bale is carried out loose in, improving under the prerequisite of loosening ratio, avoid smoked sheet to produce making broken as far as possible; Meanwhile, the smoked sheet fragrance loss that also will avoid the variation of Yin Wendu etc. to cause.But there is following point in the existing device for loosening and gaining moisture of cigarette enterprise in the especially high-grade pipe tobacco of processing cut tobacco:
One, keep this perfume of tobacco and complete between loose task and have contradiction.For making smoked sheet reach better loose effect, existing device for loosening and gaining moisture return air temperature mostly is 65 degree left and right, with this understanding, can destroy the fragrance of raw tobacco material, therefore, raw tobacco material need to, in lower Temperature Treatment condition, could more effectively be brought into play potential fragrance and use value.But loose effect and regain are poor with this understanding, tobacco flake loosening rate is many between 80% ~ 90%, can not be fine the task of completing loosening and gaining moisture.
Two, in loosening and gaining moisture process, smoked sheet is heated inhomogeneous.Raw tobacco material is pressed into fast shape vanning accumulating after redrying, lump material enters loosening and gaining moisture cylinder, material center has sub-fraction tobacco leaf and can not effectively scatter, this part tobacco leaf cannot thermally equivalent in loosening and gaining moisture process, and the variation of steam flow is that smoked sheet after scattering is heated inhomogeneous.
Three, existing device for loosening and gaining moisture broken rate is high.When cigarette piece enters drum-type tobacco leaf conditioner, block material is difficult to moisture regain at short notice, rotation due to cylinder, in cylinder, harrow nail and stir-fry plate take up cigarette piece at spiral, constantly so turn over and pound, cause tobacco leaf larger make brokenly, therefore traditional loosening and gaining moisture mode tobacco leaf broken rate in drum-type tobacco leaf conditioner is high.
