Embodiment 1

[0058] Weigh 10g of shredded tobacco and fill it into the body of quartz reaction tube 4, weigh 3 parts of 1g of alumina and add them to two straight sand core tubes 10 and sand core funnel 12 respectively, and measure 2 parts of 25ml absorption solution into the wide mouth In the bottle 13, add an amount of ice cubes and water in the ice bath 14, and insert a thermometer so as to observe its temperature. Apply vacuum silicone grease to the instrument interface. After the instrument is installed, turn on the condensed water of the all-solid induction heater 2, the transformer 3, the copper hollow coil 7 and the straight condenser tube 11, and turn on the switch of the high-pressure gas source 6 to provide a cracking atmosphere. Nitrogen, the gas flow rate is 50ml / min, then turn on the power switch of the intelligent regulator 1 and the all-solid induction heating device 2, and set the temperature rise program as follows: the initial temperature is 20°C, after 1.5min reaches 550...

Abstract

The invention discloses a method and application for selectively adsorbing aroma components in high-temperature pyrolysis flue gas of tobacco by using solid adsorption materials. In the shaped sand core tube and the sand core funnel, the absorption liquid is added in the absorption bottle, ice cubes and water are added in the ice bath and a thermometer is inserted; (2) the heating device is turned on, and the cracking atmosphere is introduced into the quartz reaction tube, and the flow rate is controlled to The gas flow rate is 30-50ml / min, connect condensed water, set the heating program of the heating device to reach 600-800°C within 1-2 minutes, keep warm at 600-800°C for 1.5-2.5 minutes, then cool to room temperature, and take out the straight sand The solid adsorption material in the core tube and the sand core funnel absorbs the aroma components in the pyrolysis flue gas of tobacco. The invention can be used to process tobacco to obtain a solid-phase material adsorbed with smoke components, which can be applied to new tobacco products to improve their sensory properties, increase the market acceptance of new tobacco products, and promote the transformation of consumption patterns.

Description

technical field [0001] The invention relates to the field of novel tobacco, in particular to a method for selectively adsorbing aroma components in high-temperature pyrolysis flue gas of tobacco by using a solid adsorption material. Background technique [0002] The "Framework Convention on Tobacco Control" formulated by the World Health Organization stipulates that the spread of tobacco smoke in public places is prohibited. The promulgation of this ban has brought a strong impact on the development of traditional cigarettes; on the other hand, new tobacco products are reducing environmental pollution. It has obvious advantages in reducing the potential risks of smoking. In addition, with the change of people's consumption concept and lifestyle, the rapid development of science and technology and the continuous acceleration of commodity upgrading, the needs and concerns of tobacco consumers are also constantly changing. In this era, countries around the world The tobacco in...
