Embodiment 1

[0027] (1) The tobacco stem expands step by step (such as figure 1 shown): after the tobacco stem passes through the feeding device 1 and the flow metering device 2, it is fed to the screening and vibrating tank device 3, and after dust and impurities are removed, it is put into the drum heating device 4 for the first heating of the tobacco stem At about 15°C, the temperature of the tobacco stems is 35°C, and then the tobacco stems enter the heating and humidifying equipment (HT) 5 for the second heating of the tobacco stems, and the temperature is 140°C, and the tobacco stems are pretreated for 10 minutes. Increase the temperature by about 15°C. After the second heating of the tobacco stems, the temperature of the tobacco stems is about 50°C, and the moisture content is controlled at about 13%. The exchanged tobacco stems are released from high pressure to normal pressure to obtain pre-expansion and third temperature increase. The temperature of the pre-treated tobacco stems ...

Embodiment 2

[0032] (1) The tobacco stem expands step by step (such as figure 1 shown): after the tobacco stem passes through the feeding device 1 and the flow metering device 2, it is fed to the screening and vibrating tank device 3, and after dust and impurities are removed, it is put into the drum heating device 4 for the first heating of the tobacco stem At about 10°C, the temperature of the tobacco stems is 30°C, and then the tobacco stems enter the heating and humidifying equipment (HT) 5 for the second heating of the tobacco stems, and the temperature is 120°C, and the tobacco stems are pretreated for 30 minutes. The temperature is increased by about 10°C. After the tobacco stems are heated twice, the temperature of the tobacco stems is 40°C, and the moisture content is controlled to about 14%. Then it enters the heat exchange equipment 6 filled with saturated steam, and is heated by saturated steam so that the heat exchanged The tobacco stems are released from high pressure to norm...

Abstract

The invention provides a comprehensive utilization technology of microwave-expanded tobacco stems. The comprehensive utilization technology comprises the following steps that 1, tobacco stems are subjected to three stages of preheating and microwave expanding treatment; 2, air cooling is conducted, wherein the microwave-expanded tobacco stems are blown forwards by a draught fan and subjected to air cooling dedusting through a dust collecting bag; 3, the expanded tobacco stems are subjected to stem slice forming processing; 4, the expanded tobacco stems are subjected to cut stem forming processing. According to the method, stem core carbonization is significantly reduced, uniform expanding is achieved, the material liquid absorption capacity is enhanced, little natural tobacco aroma is lost, scorched and woody smell is reduced, the cigarette smoking quality is obviously improved, and the effect of fully utilizing the tobacco stems is achieved.

Description

technical field [0001] The invention relates to a process for comprehensive utilization of microwave-expanded tobacco stems, which belongs to the technical field of tobacco processing. Background technique [0002] In order to improve the quality and utilization rate of tobacco stems, a variety of tobacco stem processing and application technologies have been developed in the industry. At present, the overall research direction is towards functionalization, morphological silking, improvement of filling effect, and increase of cigarette blending ratio. . Although the processing technologies all have their own characteristics, the advantages and disadvantages of these tobacco stem processing technologies are equally obvious. For example, the high-temperature and high-humidity expansion technology has a relatively simple process and low processing cost, but the processing strength is weak, the expansion rate is low, and the uniformity of blending with the cut leaves is poor; a...
