Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of a food-grade degradable environment-friendly filter rod comprises a filtering section and a cooling section, wherein a porous bar rod prepared from konjac mannan is arranged in the cooling section in a matched mode, and the porous bar rod comprises a plurality of cooling channels for smoke to pass through. The porosity of the porous bar is 50-85%, and the cooling channel is a nonlinear bending channel formed by the pores of the porous bar. The food-grade degradable environment-friendly filter tip rod can be applied to heating non-burning electronic cigarettes or traditional cigarettes. The length of the cooling section is 20-80% of the total length of the food-grade degradable environment-friendly filter rod.
The invention also provides a preparation method of the food-grade degradable environment-friendly filter rod, which comprises the following steps:
s1) selecting 1 kg of fine konjac mannan, placing the fine konjac mannan in a high-speed stirring container, adding alkali accounting for 0.3% of the mass of the fine konjac mannan, adding 3 kg of warm water, adding water, starting stirring equipment, stirring for 30 minutes to form a transparent colloid, wherein the stirring temperature is 30-40 ℃;
s2) preparing a primary forming cylindrical mold, injecting colloid into the mold, putting the mold into steam equipment after injection, and steaming for 40 minutes by high-temperature steam;
s3), after cooking, the colloid expands in a mould to form an elastic paste, the elastic paste is naturally placed for 10 minutes and then taken out, and the elastic paste is put into a refrigeration house with the temperature of minus 40 ℃ for freezing for 48 hours;
s4) after freezing, putting the raw materials into a freeze-drying device for dehydration and freeze-drying, controlling the water content after freeze-drying to be 9-12%, and obtaining a cylindrical porous semi-finished material with regular pore diameter after freeze-drying;
s5) putting the porous semi-finished product material into rolling equipment, and performing compression rolling according to the required diameter to obtain a compressed semi-finished product;
s6), spraying a setting agent into the semi-finished product after compression, then pushing the semi-finished product sprayed with the setting agent into a setting pipe by using reciprocating equipment, and standing for 60 minutes after setting is completed;
s7) finally taking out, putting the bar into drying equipment, and drying to obtain the multi-pore bar with the required specification, wherein the drying temperature is controlled at 50-80 ℃.
And then the obtained porous bar and the filter segment are coated by the plug wrap to form an integral filter rod. The working process of the invention is as follows: according to the invention, the porous material prepared from konjac mannan is applied to the cooling section in the filter tip, and as the material is a porous material, a plurality of continuous and nonlinear zigzag cooling channels for smoke to pass through are naturally formed in the pore space of the porous material, and the zigzag cooling channels have larger contact area and are more beneficial to cooling. When a smoker smokes and heats the unburnt electronic cigarette or the traditional cigarette, high-temperature smoke generated by the smoke bomb enters the cooling section, the aperture space of each cooling channel plays a role in reducing the temperature of heat flow smoke, and the porous material prepared from the konjac mannan has a good heat adsorption effect, can adsorb a large amount of heat carried by the smoke, so that moisture in the smoke is condensed, and the temperature of the smoke is reduced. The flue gas after the cooling gets into the filter segment, and the filter segment adopts macromolecular material silk system to form, can reduce the inhaling of flue gas and hinder and hold back to further improve flue gas filter effect and cooling effect. In addition, the porous material has strong filtering and adsorbing capacity, can well reduce tar content and reduce the harm of cigarettes to human bodies, and the porous material filter tip rod prepared from the pure natural konjac mannan can be naturally degraded after being used, does not cause harm to the environment, and is healthy and environment-friendly.
