Problems solved by technology

[0007] First, the material enters the drum a1 along the B' direction, and moves forward under the rotation of the drum a1, and the atomized water and steam applied to the drum a1 from the steam injection pipe a3 and the steam mixing nozzle a4 fill the entire In the inner space of the drum a1, under the action of the exhaust fan a9, the atomized water and steam are discharged from the drum a1 along the direction of the arrow indicated by A', which is opposite to the direction B' of the material, and the atomized water and steam are in contact with the material The time is short, the material cannot be soaked in a short time, the soaking rate is low, and the internal temperature and moisture content cannot meet the requirements of the process, resulting in poor processing resistance of the material and low conversion rate of cut stems.
[0008] Second, the temperature of the process hot air with steam and atomized water discharged from the drum a1 along the direction of the arrow indicated by A' is above 75°C. The discharge of the process hot air will cause a lot of energy waste and cause environmental pollution to the outside world. Not economical and not environmentally friendly
Due to the fluctuation of the tidal air volume of the back-end moisture exhaust cover a11 and the changes of the surrounding environment temperature and humidity, there is an irregular deviation between the actual processing temperature of the material in the drum a1 and the feedback temperature detected by the temperature detection mechanism a13, which affects the quality of the product Stable, and the temperature detection mechanism a13 is set near the material outlet of the discharge hood a10, affected by high temperature and moisture, the detection temperature has deviations

Embodiment Construction

[0051] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0052] The specific embodiments of the present invention are for the convenience of further description of the concept of the present invention, the technical problems to be solved, the technical features constituting the technical solution and the technical effects brought about. It should be noted that the description of these embodiments does not constitute a limitation of the present invention. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0053] Because the flow direction of the atomized water and steam in the existing barrel-type moistening machine is opposite to the direction of material travel, the contact time between the atomized water and steam and the material is shor...

Abstract

The invention relates to a cylindrical stalk moistening machine and a stalk moistening method of the cylindrical stalk moistening machine. The cylindrical stalk moistening machine comprises a rotary drum, a steam and moisture spraying mechanism, a first air returning pipe and a circulating fan. The discharging end of the rotary drum is communicated with the circulating fan through the first air returning pipe, and under the effect of the circulating fan, the flow direction of technological hot air with steam and moisture in the rotary drum is coincident with the advancing direction of materials in the rotary drum. By means of the cylindrical stalk moistening machine and the stalk moistening method, the time spent when the materials absorb steam heat energy and atomized water is lengthened to the maximum degree, the time is enough for the steam and the moisture to seep into the materials, and the material moistening rate, the tobacco stalk processing resistance, the stalk converting rate and the finished-product physical quality are improved. Further, the technological hot air is fed into the rotary drum from the feeding end of the rotary drum through the circulating fan to be recycled, the use rate of the technological hot air is improved, a large amount of energy is prevented from being wasted, and meanwhile the environment pollution, caused by exhausting the technological hot air, to the external is avoided.

Description

technical field [0001] The invention relates to the field of tobacco machinery, in particular to a barrel-type stemming machine and a stemming method thereof. Background technique [0002] Cut stems are an important part of cigarette products. Adding cut stems in cigarette manufacturing is beneficial to reduce the consumption of cigarette raw materials, improve the burning speed of cigarettes, and reduce the amount of tar in cigarettes. As the pre-cutting process, the internal and external moisture balance of the moistening treatment process is crucial to the quality of cut tobacco stems, which directly affects the physical quality and sensory properties of cut stems such as whole shred rate, shredded shred rate, filling value, etc. quality. [0003] The cylinder type stemming machine is the most commonly used stemming equipment in domestic and foreign cigarette production lines. Its main function is to treat the material at high temperature and increase the moisture conten...
