Problems solved by technology

However, there are still some problems that need to be further improved in the high-temperature and high-pressure steam expansion process. For example, the process uses a Venturi tube, and the length of the tobacco stem is required to be no more than 30 mm, so the application of the tobacco stem in my country is limited to a certain extent; at the same time, the technology is for intermittent production, etc. Wait

Embodiment 1

[0023] 100g of dried tobacco stems are used as raw material, 19g of water is added, sealed in a container and evenly moistened. Weigh 0.8 g of the pectin bulking agent, prepare a 0.6%-0.8% aqueous solution, spray evenly on the tobacco stems, and turn the tobacco stems to make the bulking agent fully contact with the tobacco stems. The pretreated tobacco stems are evenly spread in the glass vessel, and the layer thickness is 20mm. Place the glassware with tobacco stems in the microwave, turn on the microwave (2450MHz), power 400w, during the microwave puffing process of the tobacco stems, the temperature is controlled at 90°C, and the puffing time is about 90s. When the time is up, the puffed tobacco stems No carbonization phenomenon, turn off the microwave, stop puffing. The tobacco stem is puffed to 3.1 times of the original volume, and the puffed tobacco stem has no carbonization phenomenon.

Embodiment 2

[0025] 100g dry tobacco stems are used as raw material, 18g water is added, sealed in a container and evenly moistened. Weigh 0.9 g of the pectin bulking agent, prepare a 0.6%-0.8% aqueous solution, spray evenly on the tobacco stems, and turn the tobacco stems so that the bulking agent and the tobacco stems are in full contact. Spread the pretreated tobacco stems evenly in the glass vessel, and the layer thickness is 30mm. Place the glassware with tobacco stems in the microwave, turn on the microwave (2450MHz), power 400w, during the microwave puffing process of the tobacco stems, the temperature is controlled at 80°C, and the puffing time is about 80s. When the time is up, the puffed tobacco stems No carbonization phenomenon, turn off the microwave, stop puffing. The tobacco stem is expanded to 2.7 times the original volume, and the expanded tobacco stem has no carbonization phenomenon.

Embodiment 3

[0027] Take 100g of dried tobacco stems as raw material, add 21g of water, seal it in a container and evenly moisten it. Weigh 1.0 g of the pectin bulking agent, prepare it into a 0.6%-0.8% aqueous solution, spray it evenly on the tobacco stems, and turn the tobacco stems so that the bulking agent and the tobacco stems are in full contact. Spread the pretreated tobacco stems evenly in the glass container, and the layer thickness is 25mm. Place the glassware with tobacco stems in the microwave, turn on the microwave (2450MHz), power 400w, during the microwave puffing process of the tobacco stems, the temperature is controlled at 85°C, and the puffing time is about 85s. When the time is up, the puffed tobacco stems No carbonization phenomenon, turn off the microwave, stop puffing. The tobacco stem is puffed to 3.3 times of its original volume, and the puffed tobacco stem has no carbonization phenomenon.

Abstract

The present invention relates to utilization of by-product tobacco stems obtained in tobacco industry, in the concrete, it relates to a technological process for puffing tobacco stems by utilizing microwave. Said technological process includes the following steps: raw material pretreatment: uniformly spraying pectin puffing agent on the dried tobacco stems; charging: making the pretreated tobaccostems be uniformly laid in a glassware; placing the glassware into a microwave oven and utilizing microwave to puff the tobacco stems, microwave frequency is 2450MH2, power is 400w and temperature is85-95deg.C, so that the puffed tobacco stems can be obtained.

Description

technical field [0001] The invention relates to a process method for preparing puffed tobacco stems by using tobacco stems, a by-product of the tobacco industry. Background technique [0002] Tobacco stem is a by-product of tobacco production, which consists of skin and core, and contains a certain degree of lignified fiber. At present, the utilization of tobacco stem waste at home and abroad is mainly concentrated in the manufacture of activated carbon, board making, extraction of chemical raw materials and papermaking. [0003] Tobacco stem expansion granulation technology is a new tobacco processing technology that has emerged in foreign countries in recent years. Adding about 20% stem particles to cigarettes can effectively improve the filling volume and combustion performance, reduce woody odor and tar, and improve cigarette quality. At present, this technology mainly uses high-temperature and high-pressure steam (12bar, about 300°C) to expand the short stems and stems...
